Abstract

This valve relates to a valve capable of temporarily draining a fluid.

The valve of the valve is configured such that the first outlet of the housing, through which the fluid introduced into the housing is allowed to flow out, is blocked or opened by the movement of the plug, and the first outlet is opened by moving the plug through the plug moving means. The first outlet may be blocked by the stopper when the stopper is moved to open the first outlet, so that the force of the fluid generated by opening the first outlet is applied to the stopper or the stopper moving means.

The valve of the present valve may selectively open the first outlet port to draw out the fluid, but may only draw a small amount of fluid at a moment, but may not allow the fluid to be drawn out continuously.

Description

Valve {THE VALVE}

This valve relates to a valve installed in the middle of a pipeline, a container, or the like to control the flow of fluid.

Various types of valves have been developed to control the flow of the fluid, the basic shape of which depends on how to control the flow of the fluid.

In controlling the flow of the fluid, there is a case where the selective flow of the fluid occurs in a direction different from the normal flow direction, but the flow of the fluid occurs only for a short time.

For example, it may be necessary to secure a small amount of tap water samples to check the condition (eg, contamination) of tap water flowing through a specific point of a water pipe.

For this purpose, a valve may be installed at a specific point of the water pipe, and the tap water in the water pipe may be selectively discharged through the valve.

However, if the tap water can be continuously drawn out through the valve as described above, it can be a considerable loss in terms of the operator of the water supply business.

In other words, the user must use only the tap water that has passed through the water meter and pay for the amount used so that the water supply business can operate normally.

Therefore, it is possible to flow the fluid in a direction different from the normal flow direction, but it is necessary to allow the fluid to flow only for a short time.

In other words, temporary fluid outflow is required.

This necessity is more urgently needed if the effluent fluid is expensive, such as oil.

As another example, there is a case where foreign matter mixed in the fluid is filtered at a specific point, and the filtered foreign matter is selectively discharged.

Even in this case, the valve may be installed on the flow path of the fluid, and the fluid may be selectively discharged through the valve.

However, if a large amount of fluid, such as tap water, oil, natural gas, etc. can be taken out through the valve installed to remove foreign substances as described above, considerable damage may occur.

Therefore, even in the above case, it is possible to flow the fluid in a direction different from the normal flow direction, but it is necessary to allow the fluid to flow out only temporarily for a short time.

Korean Utility Model Application No. 20-2006-0020839 discloses a technique for installing two valves and allowing the two valves to move together to prevent unauthorized extraction of fluid through the valve.

However, the prior art as described above has a problem that the valve can be disconnected in a simple manner because the core components are exposed to the outside, and in such a case, the fluid can be withdrawn.

In addition, in order for the fluid to flow in a direction different from the normal flow path, the normal flow path must be blocked, and two valves have to be installed, which causes a problem of high manufacturing cost.

This valve is intended to solve the above problems, more specifically, it is possible to flow out the fluid, but only for a short time can be flowed out temporarily to minimize the loss of the fluid, and the valve that can not withdraw the fluid for fraudulent purposes The purpose is to provide.

In particular, it has an object to place various components inside the valve to prevent the unauthorized extraction of the fluid by modifying the valve from the outside of the valve.

In this valve, the inlet fluid forms a first outlet for outflow, and the first outlet can be selectively opened and closed by the movement of the stopper. When the stopper moving means moves the stopper to open the first outlet, it is applied to the stopper. The first outflow is caused by blocking the first outlet by returning the stopper by a force in a direction different from that of the stopper, or by a force applied to the stopper moving means (fluid flow force or the weight of the stopper moving rotor). Keep the fluid out of the sphere continuously.

In addition, it is difficult to continuously open the first outlet by changing the valve, and the manufacturing cost is also saved.

The valve of the valve has a force in a direction different from the movement direction of the stopper applied to the stopper when the stopper moving means moves the stopper so that the first outlet of the housing is opened and closed selectively by the movement of the stopper. Alternatively, the stopper is retracted by the force (fluid force of the fluid or the weight of the stopper moving rotor) due to the force applied to the stopper moving means, and the first outlet is automatically shut off, so that the first outlet can be selectively opened to remove the fluid. Only a small amount of fluid can be withdrawn temporarily but not continuously.

In addition, it is difficult to continuously open the mold-type first outlet of the valve to deformation, and the configuration is simple, so that the manufacturing cost is low and the failure rate is very low.

The valve relates to a valve capable of only temporarily draining fluid, wherein the first outlet of the housing, through which the fluid introduced into the housing is allowed to flow out, is blocked or opened by the movement of the stopper, and the stopper moves through the stopper. It is structured so that the first outlet can be opened by moving.

In addition, when the user operates the stopper moving means, when the first outlet is opened, the stopper is automatically returned so that the first outlet is blocked by the stopper again. The force causing the stopper to be returned is generated by opening the first outlet. It is made by the force of the fluid or the weight of the plug moving rotor which is a component of the plug moving means.

The technique of this valve will be described in more detail using the accompanying drawings.

This valve relates to a valve which is installed in a pipe or a container to allow the fluid to flow out.

Accordingly, the valve of the valve has a housing 10 in which a fluid inlet 11 is formed and a first outlet 13 formed so that the fluid flowing into the fluid inlet 11 can flow out.

In Figures 1 to 3 there is further formed a second outlet 12 through which the fluid flowing into the fluid inlet 11 flows out so that the fluid may flow out through the second outlet and also flow in the direction of the first outlet. It shows a structure that can be.

In particular, when the fluid inlet 11 and the second outlet 12 of FIG. 1 are directly connected to the pipe, the fluid can be normally flowed, and the fluid thus flowed can be discharged in a small amount through the first outlet. .

However, the valve is intended to allow the fluid to flow out, but only for a short time to flow out the fluid temporarily to minimize the loss of the fluid, it is not intended to continuously withdraw the fluid.

For this reason, the first outlet 13 of this valve is made to be selectively opened.

However, the fact that the first outlet 13 can be selectively opened does not mean that the purpose of the valve can be achieved.

The user of the valve may open the first outlet 13, but the opening does not last long, but immediately (or after a certain point) the first outlet 13 should be shut off automatically.

In the present application, the stopper 20 moves to open the first outlet 13 so that the force of the fluid generated by opening the first outlet 13 is applied to the stopper 20 or the stopper moving means 30. And a structure in which the first outlet 13 is blocked and some components of the plug moving means 30 are moved by their own weight so that the plug 20 blocks the first outlet 13.

There are two ways in which the stopper 20 moves so that the first outlet 13 is automatically shut off by the force of the fluid generated by the opening of the first outlet 13.

First, as shown in FIGS. 1 to 8, the force of the fluid generated by opening the first outlet 13 is directly applied to the stopper 20 so that the stopper 20 moves so that the first outlet 13 is again blocked. to be.

Second, as shown in Figs. 9 to 14, the force of the fluid generated by opening the first outlet 13 is applied to the stopper moving means 30, which causes the stopper 20 to move to block the first outlet 13 again. This is how you do it.

First, a method in which the force of the fluid is directly applied to the stopper 20 so that the stopper 20 moves to block the first outlet 13 again.

The valve of the present application is selectively opened and closed of the first outlet 13 by the stopper 20, but when the stopper 30 is moved to open the first outlet 13, the stopper 20 is the first outlet 13 ) Was stopped and moved to the first outlet 13 by the force (flow velocity, etc.) directed to the first outlet 13 so that the first outlet 13 was blocked.

That is, the stopper 20 which opens or blocks the first outlet port is located between the first outlet port 13 and the fluid inlet port 11 in the flow path of the fluid to move or block the first outlet port 13. It is to open the outlet (13).

In addition, by moving the stopper 20 through the stopper moving means 30, the first outlet 13 that was blocked by the stopper 20 can be opened, but the stopper 20 so that the first outlet 13 is opened. When the movement of the stopper 20 applied to the stopper 20 and the force in the other direction is greater than the set value when the stopper 20 is moved, the stopper 20 is separated out of the area affected by the stopper moving means 30 to the first outlet By moving to the position to block 13, the stopper 20 is to block the first outlet 13 again.

1 to 3, a stopper 20 is located between the first outlet 13 and the fluid inlet 11 of the fluid flow path, and the stopper 20 moves in the direction of the first outlet 13. When the first outlet 13 is blocked, the stopper 20 is moved in the direction of the fluid inlet 11, the first outlet 13 is opened.

In addition, the stopper 20 is provided with a stopper moving means 30 capable of being separated and coupled with the stopper 20. When the stopper moving means 30 is coupled with the stopper 20, the stopper 20 moves to the first outlet 13. To open the door.

1 to 3, the coupling force of the stopper 20 and the stopper moving means 30 is that the stopper 20 can move together when the stopper moving means 30 is moved, but is applied to the stopper 20. When the force in the direction of the outlet 13 is greater than the set value (coupling force of the stopper 20 and the stopper moving means 30) is the degree to which the stopper 20 and the stopper moving means 30 are separated.

In the above description, the force in the direction of the first outlet 13 applied to the stopper 20 is generated by the flow rate of the fluid flowing in the direction of the first outlet 13, the weight of the stopper 20 itself, and the like.

Separating the stopper 20 and the stopper moving means 30 in the above structure is achieved by implementing the stopper 20 to be affected by the force (flow rate, etc.) of the fluid flowing to the first outlet 13. Can be.

At this time, the force applied to the plug 20 by the fluid flowing in the direction of the first outlet 13 varies depending on how much the plug 20 is affected by the fluid flowing into the first outlet 13.

That is, the degree to which the stopper 20 is affected by the fluid is determined according to how much the fluid flowing into the first outlet 13 hits the stopper 20, and if the area where the fluid collides with the stopper 20 is large, 20 is subject to a lot of influence of the fluid (force), and if the area hit is small, the plug 20 is less affected by the fluid (force).

Therefore, the stopper 20 and the stopper moving means 30 is separated and coupled in the above structure, the coupling force of the stopper 20 and the stopper moving means 30 to achieve the purpose of the valve, that is, the stopper moving means 30 In response to the movement of the stopper 20 is moved to the first outlet 13 is instantaneously opened to the fluid outflow, but when the first outlet 13 is opened and the fluid outflow stopper 20 is plug movement means 30 The coupling force of the stopper 20 and the stopper moving means 30 which are separated from the first outlet 13 to block the first outlet 13 is a stopper 20 to the force of the fluid flowing to the first outlet 13 and the force of the fluid. Is determined in consideration of the degree of influence, the weight of the stopper 20, the degree to open the first outlet 13 by the movement of the stopper movement means 30, such matters are determined in the technical field of the valve It can be obtained by those skilled in the art through well-known design techniques calculation The detailed description of this part is omitted.

While explaining the stopper moving means 30, the stopper 20 can be moved to open the first outlet 13, which was blocked by the stopper 20, but the stopper 20 so that the first outlet 13 is opened. When the movement of the stopper 20 applied to the stopper 20 and the force in the other direction is greater than the set value when the stopper 20 is disengaged so that the stopper movement means 30 is unable to move the stopper 20 Has been described.

The term 'set value' refers to a force exceeding the force described above that can be obtained through the above calculation technique.

That is, in the condition that the force applied to the stopper 20 is weaker than the coupling force of the stopper 20 and the stopper moving means 30, the first outlet 13 is opened, but if a force greater than the coupling force is applied, the stopper ( 20 and the stopper moving means 30 is separated so that the stopper 20 blocks the first outlet 13 so that the fluid can not flow to the first outlet (13).

When the stopper 20 is moved by the stopper moving means 30 and the first outlet 13 is opened, the fluid is discharged to the first outlet 13, and the stopper is driven by the force of the fluid discharged to the first outlet 13. The stopper 20 and the stopper moving means 30 for separating the moving means 30 and the stopper 20 and blocking the first outlet 13 by the stopper 20 may be implemented in various forms. have.

Referring to a specific example, it can be implemented to be a combination of the plug 20 and the plug moving means 30 by a magnetic force.

1 to 3, the magnet 31 is positioned at a portion of the plug moving means 30 that is in contact with the plug 20 so that the stopper 20 contacts the magnet 31 of the plug moving means 30. When the combination of the 20 and the stopper moving means 30 is made, and the force in the direction of the first outlet 13 applied to the stopper 20 is greater than the coupling force of the stopper 20 and the stopper moving means 30 ( Occurs when the first outlet 13 is opened. The stopper 20 and the stopper moving means 30 are separated.

Portion and the stopper of the stopper moving means 30 in contact with the fluid is preferably implemented by a material such as brass or stainless steel, which is highly corrosion-resistant, there are some materials that do not respond to magnetic forces.

In this case, it is possible to use a method of attaching a strong corrosion-resistant magnetic material to the magnet and the portion to be attached.

If a magnet is provided to the stopper moving means 30, the magnetic body is attached to the stopper. On the contrary, if a stopper is provided to the stopper, the magnetic body is attached to the stopper moving means 30.

In the structure in which the stopper 20 and the stopper moving means 30 are coupled by magnetic force, it is necessary to prevent the magnetic force acting on the outside of the housing 10 from being transmitted to the stopper 20 inside the housing 10. .

This is to prevent the movement of the stopper 20 by placing a separate magnetic force generating means on the outside of the housing 10 in an unintended intention.

To this end, it is preferable to implement the housing 10 with a nonmagnetic material, and thick.

Of course, in implementing the housing 10, it is more preferable to implement the material to which magnetic force does not pass or to post-process so that magnetic force does not pass after the housing is manufactured.

1 to 3, the stopper 20 is separated from the stopper moving means 30 by a force applied in a direction opposite to the moving direction for the opening of the first outlet 13.

However, the release of the coupling force of the stopper 20 and the stopper moving means 30 need not be limited to the opposite direction to the movement direction of the stopper.

In the case of FIG. 6, the stopper 20 and the stopper moving means 30 are coupled by magnetic force, and when the stopper is moved and opened, the fluid 20 stops at the side of the stopper 20 so as to flow out of the first outlet. While hitting toward the first outlet, the stopper 20 and the stopper moving means 30 can be separated.

Therefore, the stopper 20 may be separated from the stopper moving means 30 by a force in a direction other than the direction in which the stopper moving means 30 moves.

1 to 3 is coupled to the stopper 20 and the stopper moving means 30 by the magnetic force, but the coupling structure of the stopper 20 and the stopper moving means 30 is not limited to such a form.

As a further coupling structure of the stopper 20 and the stopper moving means 30, the groove 32 having the locking jaw 32a and the groove 32 are fitted to the locking jaw 32a, but not to the stopper 20. When the force in the direction of the first outlet 13 is greater than the set value can be implemented in the form as shown in Figure 4 having a locking projection 33 is separated from the groove (32).

The shape of the locking protrusion having the above structure may be implemented in various ways.

In FIG. 4, the stopper 20 has a groove 32 having a catching jaw 32a, and the stopper moving means 30 has a catching protrusion 33 that is fitted into the groove 32 and is caught by the catching jaw 32a. have.

In addition, the locking protrusion 33 is formed into a plurality of parts, so that when the force in the direction of the first outlet 13 applied to the stopper 20 is strong, each part of the locking protrusion 33 (of the split shape) Part), the locking projection 33 is separated from the locking groove 32.

When engaging, it may be inserted into the locking groove 32 because the locking projection 33 is retracted.

The structure having the locking projection 33 and the locking groove 32 as described above has the advantage that it is more difficult to apply a deformation to the valve, that is, to apply a deformation to the valve so that the fluid is continuously discharged through the first outlet (13). .

As another coupling structure of the stopper 20 and the stopper moving means 30, there is a form that the coupling is made by the friction force between the stopper 20 and the stopper moving means (30).

That is, when the stopper 20 and the stopper moving means 30 are coupled to each other, a protrusion is inserted into the groove or the hole to be coupled, but is rigidly coupled to generate a strong frictional force, and the frictional force is the first outlet 13. While the stopper 20 can be moved to open, a strong force is applied to the stopper 20 so that the stopper 20 and the stopper moving means 30 can be separated. (Not shown)

That is, when a force of fluid directed toward the first outlet 13 is applied to the stopper 20 while the first outlet 13 is open, frictional force generated between the stopper 20 and the stopper moving means 30 Is to be released.

In this case, a method for tightly coupling the protrusion when the protrusion is inserted into the groove or the hole may be implemented in various forms known in the art.

However, it is preferable that the grooves or holes have elasticity like rubber or the outer diameter of the protrusions have elasticity like rubber so that separation and coupling can be easily and tightly fitted.

In the above-described structure, the stopper moving means 30 can be implemented in various forms.

However, it is preferable to implement in the form as shown in Figures 1 to 4 because the structure is simple and fewer failures.

In FIG. 1, the housing 10 has a packing installation space 16 extending in the opposite direction of the first outlet 13 and a packing installation hole 17 formed at an upper portion of the packing installation space 16.

In addition, the stopper moving means 30 has a cover 34 which is movable in the direction of the first outlet 13 in the outer side of the packing installation space 16 or in the opposite direction, one side is connected to the cover 34 It is configured to include a moving rod 35 having a portion that moves with the cover 34 and is separated from the stopper 20, the coupling is made.

In addition, the packing installation space 16 of the housing 10 is blocked to prevent leakage, but the packing 50 is further provided with a moving rod 35 is inserted into the two rod installation hole 51 formed inside.

Therefore, when the cover 34 is pulled in the opposite direction of the first outlet 13, the moving rod 35 is moved in the opposite direction of the first outlet 13 without leaking.

Of course, the moving rod 35 may be moved in the direction of the first outlet, and even in this case, no leakage occurs.

Such a structure does not require complicated processing at the time of fabrication of the component, has a small number of components, and has a very low probability of failure.

The stopper moving means 30 may be implemented in the form of having a bolt that is spirally coupled to move in the direction of the first outlet 13 or in the opposite direction when the screw is rotated.

That is, the spirally coupled bolts are rotated forward or reversely so that the bolts move in the stopper 20 direction or the opposite direction, and the bolts move in the stopper 20 direction so that the bolts are coupled with the stopper 20 and the bolts. It may be implemented in the form of moving the stopper 20 by moving in the opposite direction.

In FIGS. 1 to 4, the stopper 20 moves together by the stopper moving means 30 in a state where the stopper 20 and the stopper moving means 30 are coupled, but the technical spirit of the valve is limited to such a form. It doesn't happen.

The stopper 20 is moved by the stopper moving means 30 so that the first outlet 13 is opened, but the stopper moving means 30 and the stopper 20 are not completely contacted by the stopper moving means 30. 20) may move.

For example, the moving rod 36 which can be moved in the direction of the plug 20 or vice versa in implementing the plug moving means 30;

A moving button 37 capable of moving the moving rod 36 in the stopper 20 direction;

When the moving rod 36 is moved by more than a set point when the moving rod 36 moves in the stopper 20 direction by the moving button 37, the moving rod 36 may be embodied in a structure having a home position means 38 for moving in the opposite direction. (See Figure 7).

In this structure, the magnetic force is generated in any one of the movable rod 36 and the stopper 20, so that the stopper 20 moves in the direction of the stopper moving means 30 when the movable rod 36 moves in the stopper direction. (13) is opened, the movable rod 36 is moved to the position before the movement by the original position means 38 after moving in the stopper direction, the stopper 20 is the force generated by opening the first outlet (13) By moving in the direction of the first outlet 13 by the gap between the stopper 20 and the moving rod 36 is to prevent the magnetic force from affecting the stopper 20 to block the first outlet (13).

The home position means 38 may be implemented by applying a known technique applied to various industrial fields.

For example, it can be implemented in the same manner as the in-situ means provided in the four blood needle device.

As described in Korean Utility Model Application No. 20-2002-0012172, the bleeding needle mechanism is mainly used for the purpose of draining dead blood. This bleeding needle is moved backwards after the pointed part is momentarily advanced by pressing the move button. It is a structure that is in place.

1 to 3 are attached to the stopper 20 for opening and closing the first outlet 13 is located inside the valve, the part controlling the movement of the stopper 20 is also most of the stopper 20 Since it is located inside, the fluid cannot be drawn out continuously through the valve of this valve.

In particular, the structure having the movable rod 35 and the cover 34 as shown in FIG. 1 is difficult to deform the part controlling the blocking of the first outlet 13 in order to continuously drain the fluid to the first outlet 13. Because it is very stable.

In implementing the stopper moving means 30 in the above-described structure, it is implemented to be movable in the coupling direction with the stopper 20 (the direction in contact with the stopper 20 in the state blocking the first outlet 13) In the state where no external force is applied, it is preferable that the stopper moving means 30 moves naturally in the engagement direction with the stopper 20 by the spring 40.

That is, by removing the force applied to the stopper moving means 30 in the state in which the stopper 20 is moved by moving the stopper moving means 30, the stopper moving means 30 is returned to its original position by a spring.

The above-described structure is a structure in which the force of the fluid generated by opening the first outlet 13 is directly applied to the stopper 20 so that the stopper 20 moves to block the first outlet 13 again.

Next, a force of the fluid generated by opening the first outlet 13 is applied to the stopper moving means 30, which causes the stopper 20 to move so that the first outlet 13 is again blocked. This will be described with reference to FIGS. 9 to 14.

The stopper moving means 30 of FIGS. 9 to 14 have a stopper rotating body 39 which is rotated to block and open the first outlet, and the stopper moving body 39 is located from the center of rotation to the vicinity of the edge. The distance has a point relatively close to the point 39a.

In addition, when the stopper moving rotor 39 is placed at a point 39a, which is far from the center of rotation, is set (a point where the stopper 20 can contact the stopper 20 and push the stopper 20 upward). 20 is moved to open the first outlet 13, and when the deviation from the set point the stopper 20 is in place to the first outlet 13 is blocked.

In addition, it is made by the operator's operation that the point 39a, which is far from the center of rotation of the stopper moving rotor 39, is set at the point set for the opening of the first outlet, and is set in the state set at the set point. Deviation from the point is caused by the force of the fluid generated by opening the first outlet.

That is, in the state as shown in FIG. 9A, the point 39a far from the center of rotation of the plug moving rotor 39 faces downward, so that the movement of the plug is not affected by the plug moving rotor 39. It is a state.

However, when the stopper moving rotor 39 is rotated so that a point 39a far from the center of rotation is directed toward the stopper 20, the stopper moves in contact with the stopper moving rotor 39, and in this state, the stopper moving rotor When the 39 is further rotated, as shown in FIG. 9C, the stopper 20 moves upwards to open the first outlet 13.

However, when the stopper moving rotary body 39 is further rotated, the point farthest from the center of rotation of the stopper moving rotating body 39 is in contact with the stopper 20 so that the stopper 20 moves to the highest point in FIG. 9. The stopper 20 is moved downward as shown in D. (In FIG. 9, the stopper 20 hits the fluid flowing when the load of the stopper 20 itself and the first outlet 13 are opened. It is the original structure.)

In addition, the first outlet port is closed when it is in the same state as in FIG. 9 and A, which is further rotated so that the point 39a far from the center of rotation of the stopper moving rotor 39 faces downward.

The stopper moving means 30 in FIG. 9 has a rotating shaft 36b which is rotated by a user's manipulation.

In addition, the stopper movement rotating body 39 and the rotating shaft 36b is connected so that the stopper moving rotating body 39 can rotate together when the rotating shaft 36b rotates, but the locking projection 36c formed on the rotating shaft 36b is The stopper moving rotor 39 is rotated together by being caught by the locking jaw 39c formed at a portion of the stopper moving rotor 39.

However, as shown in FIG. 9D, when the first outlet 13 is opened in a predetermined amount, the fluid flowing through the stopper 20 hits the stopper moving rotor 39 and flows out, thereby causing the stopper moving rotor 39 to be discharged. Since the stopper 36c is not rotated because the rotational force is generated, the stopper moving rotor 39 is rotated so that the stopper moving rotor 39 does not affect the movement of the stopper 20, such as A of FIG. 9. Return flammably to

Therefore, unless the user forcibly rotates the rotary shaft 36b so as to be in a state as shown in FIG. 9C, the stopper 20 blocks the first outlet 13 to maintain a state in which the fluid cannot flow out.

That is, the deviation from the set point in a state in which the point 39a far from the rotation center is set at the set point (a point at which the stopper 20 can be moved to open the first outlet 13) is out of the first outlet ( 13) is to be made by the force of the fluid generated by the open.

10 and 11 exemplarily illustrate a structure for connecting and connecting the rotating shaft 36b and the stopper moving rotor 39 in the structure having the locking protrusion 36c and the locking step 39c. In addition to the connection method of FIGS. 10 and 11, various methods may be applied and connected.)

FIG. 9 illustrates a case in which the stopper moving body 39 is forcibly moved because the locking protrusion 39c is continuously rotated while the locking protrusion 36c is caught by the locking step 39c.

However, in addition to the structure having the locking projection 36c and the locking projection 39c as described above, the purpose of the valve may be achieved through a structure using friction force or magnetic force.

In detail, the frictional force or the magnetic force is generated between the stopper movable rotating body 39 and the rotating shaft 36b.

FIG. 13 illustrates an example of a method using a friction force. In FIG. 13, an elastic rubber 31b is positioned between the rotation shaft 36b and the stopper moving rotor 39.

Therefore, when the rotating shaft 36b is rotated, the stopper movement rotating body 39 is rotated.

However, when a force stronger than the friction force is applied to the stopper moving rotor 39, the stopper moving rotor 39 is rotated regardless of whether the rotating shaft 36b is rotated, thereby forming a cycle as shown in FIG. 9.

The magnetic force may also be implemented in the same structure as the friction force.

However, the means for securing the magnetic force is installed in place of the means for securing the friction force.

By the way, the method using the friction force may occur a phenomenon that can not maintain its original function over time due to the wear phenomenon.

In addition, the method using the magnetic force has a number of disadvantages.

In addition, the method using the friction force or the magnetic force is the weight of the fluid or plug movement rotating body 39 flowing when the plug movement rotating body 39 is rotated in the same state as in FIG. When a strong rotational force is generated in the stopper moving rotating body 39 by the center, it may not be maintained in the state as shown in A of FIG. 9 but may be in the same state as in C of FIG. have.

Therefore, as shown in FIGS. 9 to 11, the method using the locking projection 36c and the locking step 39c has a low failure rate and high accuracy.

That is, in the case of FIG. 9 to FIG. 11, even when a strong rotational force is generated in the stopper moving rotor 39 in the same state as in FIG. 9, since the locking jaw 39c is caught by the rear of the stopping protrusion 36c, the stopper movement meeting The whole 39 is no longer rotated and will remain in the state as shown in FIG.

In FIG. 9, the fluid flowing through the stopper 20 hits the stopper moving rotor 39 by opening the first outlet 13, thereby securing the rotational force of the stopper moving rotor 39, but the rotational force by the fluid. It may be implemented in a structure that is not secured.

However, it is preferable that the fluid flowing as shown in FIG. 9 impinges upon the stopper moving rotor 39. In this case, the point 39a, which is far from the center of rotation, is set (opening of the first outlet 13). It is necessary to ensure that a strong rotational force is secured by hitting the plug moving rotor 39 so as to reliably deviate from the point).

To this end, in Fig. 9, a rotational force generating groove 39b is formed on the side of the stopper moving rotor 39.

That is, when the fluid hits the rotational force generating groove (39b) is not hitting the curved surface, but a stronger rotational force is secured by hitting the plane.

The first outlet 13 is opened so that the fluid flowing through the plug moving rotor 39 flows, and the plug moving rotor for securing a strong rotational force of the plug moving rotor 39 due to the fluid colliding. It is more preferable that the structure of 39 is an impeller shape as shown in Fig. 12 rather than a cam shape which is approximately circular as shown in Fig. 9. (Of course, when the fluid impinges on each wing formed in the impeller, the fluid is winged. Hit at an angle close to the vertical to get a stronger torque.)

12, the drip tray space 39e is formed in the plug moving rotary body 39 having an impeller shape.

According to this structure, when the stopper 20 moves finely and a small amount of fluid leaks out, the spilled fluid is collected in the drip space 39e, and the stopper moving rotor 39 is formed due to the weight of the collected fluid. Is rotated and the stopper closes automatically.

It has a locking projection 36c and a locking jaw 39c in order to rotate the plug movement rotating body 39 by the rotation of the rotary shaft 36b, the fluid moving against the plug moving rotating body 39, the plug moving rotating body In the structure in which the rotational force of 39 is secured (see Fig. 9), it is preferable that the rotational force of the stopper movement rotating body 39 generated by the fluid does not become opposite to the direction in which the locking projection 36c is rotated.

This is because the opening state of the first outlet 13 can be maintained when the rotational force of the stopper moving rotor 39 generated by the fluid becomes in the opposite direction to the direction in which the locking projection 36c is rotated.

Therefore, it is preferable that the rotational force of the stopper moving rotor 39 generated when the fluid hits the stopper moving rotor 39 matches the direction in which the locking projection 36c is rotated.

In the above-described structure, the force of the fluid generated by opening the first outlet 13 may correspond to the flow force of the fluid being flown.

However, the first outlet may be blocked by the weight of the fluid, not by the flow force of the fluid.

Specifically, the fluid flowing out when the first outlet 13 is opened to fill the container 36d, and when the fluid is filled in the container 36d, the first outlet 13 is blocked.

At this time, the fluid filled in the container 36d is removed from the container 36d after a predetermined time point to enable the repeated operation.

In Fig. 17, a hole is drilled in the lower portion, and the fluid filled in the container 36d is gradually discharged, and the container 36d is emptied so that repeated operation is possible.

In FIG. 17, when the rotating shaft 36b is rotated, the container 20 is rotated together by the frictional force with the rotating shaft 36b to move the stopper 20 so that the first outlet 13 is opened and the fluid is filled in the container 36d. A force stronger than the frictional force between the rotating shaft 36b and the container is generated (force due to the weight of the fluid), so that the container rotates regardless of whether the rotating shaft 36b is rotated.

However, the method of using the weight of the fluid may be variously modified in addition to the structure shown in FIG. 17.

Up to now, the structure in which the force of the fluid generated when the first outlet 13 is opened is applied to the stopper 20 or the stopper moving means 30 to block the first outlet 13 again.

Next, a structure in which the first outlet 13 is blocked by the weight of the plug moving means 30 when the first outlet 13 is in the open state will be described.

In this structure, the stopper moving means 30 has a stopper moving rotor 39 which is rotated for the blocking and opening of the first outlet 13, and the stopper moving rotor 39 has a first outlet 13. When rotated so as to block the first outlet 13 in a state of being rotated to open, it is a structure that is rotated by the weight of the stopper movement rotating body 39 itself even if no external force is applied.

In this structure, the plug moving rotor 39 is rotated regardless of whether the rotating shaft 36b is rotated by the force of the fluid flowing when the first outlet 13 is opened. Corresponding to the structure that the weight of the stopper moving rotating body 39 itself.

Specifically, the structure as shown in Figure 9, but the frictional force is applied between the stopper movement rotating body 39 and the rotating shaft 36b can be rotated together with the rotating shaft 36b and the stopper moving rotating body 39, The stopper moving rotor 39 is in a space not in contact with the fluid and may be described as a case where the stopper moving rotor 39 is heavily implemented.

In this case, since the frictional force between the rotating shaft 36b and the stopper moving rotor 39 is not large, when the rotating shaft 36b is slowly rotated, the heavy stopper moving rotor 39 can be rotated in a state as shown in C or D of FIG. 9. none.

However, when the rotary shaft 36b is momentarily rotated rapidly, it becomes a state as shown in C or D of FIG. 9 due to the action of acceleration, etc., and then becomes the same as A of FIG. .

At this time, the stopper moving rotor 39 is the same as A in FIG. 9 in a state such as C or D of FIG. 9 that a point 39a far from the center of rotation is relatively heavier and heavier than other parts. This is because of the principle of rotation to the bottom.

In the valve, the stopper 20 moves in the direction of the first outlet 13 to block the first outlet 13 may be implemented in various forms known in the art.

However, the structure using the packing, that is, the structure in which the first outlet 13 is blocked through the leak-proof structure in which the packing is located between the housing 10 and the stopper 20 has a high failure rate.

The reason for this is that over time, the packing cannot fully perform its function, and damage to the packing occurs during operation.

Therefore, the hard stopper 20 (the stopper made of metal or synthetic resin) is in direct contact with the housing 10 so that the first outlet 13 is blocked, but the stopper 20 and the housing 10 are in close contact with each other so that a gap does not occur. It is desirable to have a structure that can.

That is, it is possible to reliably block the flow of the fluid without using a packing that frequently causes damage.

To this end, an inclined surface 18 is formed at a point of contact with the stopper 20 to block the first outlet 13 of the housing 10 or to block the first outlet 13 of the stopper 20. For example, the inclined surface 21 may be formed at a point of contact with the stopper 20.

That is, the manner in which the plane and the plane contact each other is likely to generate a gap in the contact surface.

However, when the stopper 20 has the inclined surface 20 or the housing 10 has the inclined surface 18 as shown in the drawing, the housing 10 and the stopper 20 may be in close contact with each other.

The inclined surface of the plug 20 as described above can be obtained by processing in the form of a truncated pyramid or a truncated cone.

However, machining a pyramid with the top cut off is not as easy as precision machining with a cone with the top cut off.

Machining an object in the shape of a pyramid cut off at the top is a method of cutting through a milling machine or the like after grinding, which is a significant difficulty in ensuring that multiple surfaces have the same angle or a set angle.

In addition, there is a significant difficulty in precisely treating the edges to such an extent that fluid cannot flow out.

On the other hand, processing into the shape of a truncated conical column means that the object is fixed on a lathe, rotated, cut, or cut and polished, so that not only edges are formed on the sides, but also the same slope in all directions. .

Therefore, the processing of the cone in the form of the top cut off is not only easy to process, but also more likely to be in close contact to prevent leakage.

Of course, as shown in the figure, the inclined surfaces 18 and 21 are formed on both the stopper 20 and the housing 10, so that the inclined surface 18 and the inclined surface 21 may be implemented in close contact.

In this valve, the foreign matter mixed in the fluid in the process of the fluid via the flow paths (14, 15) can be implemented to be discharged to the first outlet (13).

To this end, on the flow path from the fluid inlet 11 to the second outlet 12 is provided with a strainer (60) for filtering foreign matter mixed in the fluid, foreign matter filtered by the strainer (60) from the fluid inlet (11) It may be implemented to collect on the flow path 15 toward the first outlet (13).

When implemented in this manner, foreign substances filtered together with the fluid may be discharged when the first outlet 13 is opened.

In particular, when the first outlet 13 is opened by the stopper 20, the valve is strongly discharged to the first outlet 13 due to the pressure, so that foreign matters flow out cleanly.

In this valve, when the first outlet 13 is blocked by the stopper 20, the stopper 20 is moved to open the first outlet 13 without using the stopper moving means 30. It is desirable to make it impossible.

In the case of FIG. 1, the stopper 20 may move by pushing the wire in the stopper 20 direction through the first outlet 13, thereby allowing the first outlet 13 to be opened.

Therefore, it is preferable to implement so that the stopper 20 can not be moved through the first outlet (13).

To this end, in implementing the housing 10, when the straight object without bending is pushed in the direction of the stopper 20 through the first outlet 13, the straight object without bending does not come into contact with the stopper 20. It can be implemented in the form

In FIG. 4, when the straight object 2 that is not bent into the first outlet 13 is pushed in, the straight object that is not bent is blocked by the inner wall of the housing 10 before contacting the stopper 20. It may not be in contact with the stopper 20 through.

In addition, even if the flexible wire is pushed in the direction of the plug 20 through the first outlet 13, the flexible wire is blocked by the inner wall of the housing 10, so the flexible wire cannot move in a direction different from the direction in which the plug 20 is installed. The stopper 20 cannot be moved even through the wire.

In the accompanying drawings, a flow path 15 directed to the first outlet 13 is formed perpendicular to the flow path 14 directed to the second outlet 12.

However, in the structure in which the plug 20 is moved by the force of the fluid flowing by opening the first outlet 13, the flow path 15 toward the first outlet 13 is directed toward the second outlet 12. It is preferably formed to be inclined to.

According to such a configuration, the plug 20 can receive a large pressure of the fluid directed to the second outlet 12.

In the valve of the present valve, when it has a rotary shaft which projects and rotates outward from the inside of the housing 10, a packing for preventing leakage may be located between the rotary shaft and the housing 10.

However, the use of packing has a high rate of failure.

In order to solve this problem, the present valve proposes a structure that can prevent leakage without the packing.

For example, as shown in FIG. 9, the rotating shaft 36b rotated by the user to open the first outlet 13 among the plug movement means 30 of the valve is projected outward from the inside of the housing 10. When the structure is present, the packing can be installed so that no leakage occurs due to the rotary shaft 36b.

However, it is necessary to have a structure that prevents leakage without using the packing because there is a disadvantage of high failure rate using the packing.

As a method for this, in the valve, the housing 10 and the rotating shaft 36b have close contact portions 19 and 36e in close contact with each other, and the close contact portion 19 and the rotating shaft 36b of the housing are caused by the elastic force of the elastic body 70. The close contact portion 36e of the to propose a structure to prevent leakage between the housing 10 and the rotating shaft 36b.

The close contact portion 19 formed on the housing 10 or the close contact portion 36e formed on the rotating shaft 36b has a circular cross section and is narrowed to form an inclination or a shape corresponding thereto (for example, an upper portion). Is the shape of the hole corresponding to the shape of the truncated cone).

The close contact portion 19 of the housing 10 or the close contact portion 36e of the rotation shaft 36b has a circular cross section, which is narrowed to form a slope or a corresponding shape. This is because the rotation shaft 36b can be rotated.

The shape having a circular cross section and narrowing to form an inclination means a shape having a cone or a spherical surface cut in the upper portion thereof (see FIG. 15).

In addition, the shape corresponding to the shape of narrowing and inclining while having a circular cross section means the shape of a cone whose top is cut off or the shape of a hole corresponding to a spherical surface.

If the close contact portion 19 of the rotating shaft 36b has a circular cross section and is narrowed to form an inclination, the rotating shaft 36b may be formed even if the close contact portion 36e of the housing 10 is in the form of a hole having no inclination. When the close contact portion 36e of the housing 10 is pressed against the close contact portion 19, the gap between the close contact portion 36e of the rotary shaft 36b and the close contact portion 19 of the housing 10 does not occur.

On the contrary, if the close contact portion 10 of the housing 10 has a circular cross section as described above and is in the form of a hole corresponding to a shape that forms a slope, the close contact portion 19 of the rotating shaft 36b does not have an inclination. Although the cylindrical portion 19 of the housing 10 is pressed against the tight portion 36e of the rotary shaft 36b, the tight portion 19 of the rotary shaft 36b and the tight portion 19 of the housing 10 may not be cylindrical. There is no gap between).

Of course, when both the close contact portion 36e of the rotary shaft 36b and the close contact portion 19 of the housing 10 form the inclination as described above, the close contact portion 36e of the rotary shaft 36b or the close contact between the housing 10 is formed. Less wear occurs between the sections 19, there is a feature that can increase the stability of the leakage prevention.

Machining the contact portion 36e of the rotating shaft 36b or the contact portion 19 of the housing 10 to have the shape described above can be performed by various methods.

First, the processing to have the shape as described above can be implemented by fixing the housing 10 or the rotating shaft 36b to a lathe, a kind of machine tool, and processing it with a bite (cutting cutter, grinding wheel, etc.).

If the housing 10 having a structure that is difficult to enter the bite to the contact point to be formed, the hole for entering the bite can be drilled, and the finishing work for sealing by inserting the finishing material into the hole can be performed separately.

As another method, in implementing the housing 10 as shown in FIG. 12 or 14, the main body 10b except for the close contact part forming body 10a and the close contact part forming body 10a in which the close contact part 19 is formed. It can be made of).

In other words, by processing the close contact portion forming body (10a) easy to process is coupled to the main body (10b).

As a method of combining the main body 10b and the close contact body 10a or the holes for entering the bite and combining the finishing material so as to prevent leakage, the fitting method, the welding method after the fitting, Various methods may be used, such as bonding through a chemical binder.

The close contact portion 36e of the rotating shaft 36b and the close contact portion 19 of the housing 10 are brought into close contact with each other by the elastic force of the elastic body 70. It is for maintaining the close contact portion 19 in a close state.

In particular, even if abrasion occurs in the close contact portion 36e of the rotary shaft 36b and the close contact portion 19 of the housing 10 due to the rotation of the rotary shaft 36b, the close contact portion of the rotary shaft 36b is worn by the amount of worn. It is to ensure that the adhesion force is secured by moving in the direction of the contact portion of (). Of course, the contact portion of the housing 10 is preferably in the form of a hole corresponding to the shape of the truncated cone.)

The elastic body 60 includes high elastic rubber, coil springs, and leaf springs, and the like, in order to provide a valve having a low failure rate and a long service life, the elastic body 60 may be implemented in the form of a metal spring.

The leaf spring can be implemented in various forms known in the art. The upper and lower portions (parts in contact with the object) that transmit the elastic force are flat, and the elastic force is generated by the shape between the upper and lower portions, but a torsion phenomenon occurs between the upper and lower portions. It is preferable to implement in the form of a leaf spring that is not, because the smooth rotation of the rotating shaft 36b is possible.

That is, since the rotating shaft 36b is to be rotated, it is not preferable if there is difficulty in the rotation of the rotating shaft 36b due to the elastic body 60.

In the case of the coil spring, if the upper end and the lower end are in direct contact with the housing 10 and the rotating shaft 36b, the rotation of the rotating shaft 36b may not be smooth.

In the case of the coil spring, even if the upper end and the lower end have a flat surface, the rotation of the rotation shaft 36b is not smooth because the twist between the upper end and the lower end is caused by the rotation of the rotation shaft 36b. There is a tendency to go back)

However, if the upper part and the lower part contacting the object form a plane and the shape between the upper part and the lower part is not twisted, the upper part and the lower part of the spring are in direct contact with the object (rotating shaft 36b or rotating object with rotating shaft 36b) to be rotated. Even if it is, the rotation of the rotating shaft 36b is smooth.

In FIGS. 16A and 16B, the spring has a flat shape, and the top and the bottom are flat, and the top and bottom of the spring are not twisted even when the rotating shaft 36b is rotated.

In the case of the leaf spring shown in FIG. 16C, there is no twist between the upper end and the lower end.

Of course, in the structure using the coil spring, high elastic rubber, or the like as the elastic body 60, by installing a separate sliding member 80 between the rotating shaft 36b and the elastic body 60 to smoothly rotate the rotating shaft 36b. It may be. (See FIG. 14)

The sliding member 80 is to enable a smooth rotation of the rotating shaft 36b, the surface is made of a smooth material or has a form in which the contact area with the rotating body 14 is minimized.

Preferably, the sliding member 80 may be implemented in a bearing form such as a thrust bearing.

1 to 7 when the stopper 20 is caught by an object (a sieve 60 in the drawing) in the process of moving the stopper 20 by the stopper moving means 30 in the structure as shown in FIG. 1 to FIG. And stopper moving means 30 is more reliably separated, the stopper 20 is to block the first outlet (13).

The valve of this valve may be provided in objects, such as a water meter.

Reference numeral 1 is a pipe connected to the fluid inlet 11 and the second outlet 12 of the valve.

In addition, reference numeral 22 is an area that is coupled to the stopper moving means 30.

That is, the portion indicated by the oblique line in FIG. 5 indicates a region coupled with the stopper moving means 30.

Therefore, the outer side of the region 22 coupled with the stopper moving means 30 among the upper portions of the stopper 20 shown in FIG. 5 corresponds to a portion subjected to a force hit by the fluid flowing toward the first outlet 13.
