The present invention relates to an on / off valve device for opening and closing a fluid by pneumatic pressure, and more particularly, because the opening and closing operation by a variety of simple methods, precise control of the opening and closing operation, and the transfer of the fluid, such as the fluid can be made quickly and smoothly. The on-off valve device for fluid transfer to maximize the reliability of the.

In general, the valve for opening and closing the fluid transfer is widely used as a means for controlling the flow of the fluid by the opening and closing operation of the pipe is provided on the pipe installed for the transfer of the fluid and the like.

Such a conventional opening and closing valve has an inlet hole 13a and an outlet hole inside the main body 10 to which the left and right split bodies 11 and 12 are mutually coupled, as shown in FIGS. 1 and 2. 13b) and an inner flow passage 13 forming a curved guide groove l3c toward the exit hole 13b, and an opening and closing surface 22 on one side with a flow hole 21 inside the center thereof. The opening and closing operation side 20 is formed to be inserted into the reciprocating movement operation of the predetermined distance, the inner side of the guide groove (13c) to form a through-hole 31 in the circumference and on one side of the opening and closing operation side 20 The disk 30 to which the opening and closing surface 22 is pressurized is fixedly installed.

In this case, the opening and closing operation side 20 protrudes the pressurizing operation protrusion 25 along the outer circumference to form the pneumatic chambers 15a and 15b, but each of the pneumatic chambers 15a and l5b is a closed air injection hole. 16a and an open air injection hole 16b are formed.

Looking at the operation of the on-off valve, first, in the opening operation, as shown in Figure 1 by injecting air pressure through the open air pressure injection hole (16a) to pressurize the pressing operation projection 25 of the opening and closing operation valve 20 In operation, the opening / closing operation side 20 moves toward the inlet hole 13a, and at the same time, the opening / closing surface 22 at the tip of the opening / closing operation side 20 is spaced apart from the disk 30 to open the flow path 13. do.

In this way, while the opening and closing operation side 20 opens between the disk 30 and the fluid introduced through the inlet portion 13a and the inner flow passage 13, the fluid guide groove 13c on the flow passage l3 is provided. Guided to be continuously conveyed through the through hole 31 and the outlet hole (13b) of the disk (30).

In addition, when the closing operation of the valve as shown in Figure 2 when the air pressure is injected through the closed air injection hole (16b) to pressurize the pressing operation projection 25 of the opening and closing operation valve 20, the opening and closing operation valve ( As the 20 moves toward the exit hole 13b, the opening / closing surface 22 at the tip end of the disk 30 is pressed against the disk 30 to close the flow path 13.

In this way, the opening and closing operation side 20 is closed between the disk 30, so that the fluid flowing through the inlet 13a and the inner passage 13 is no longer the through hole 31 and the outlet of the disk 30 Will not be transported through the ball (13b) is to block the flow of the fluid.

However, such an open / close valve is controlled only by the air pressure injected into the open and closed air pressure injection holes 16a and 16b. By the pressure of the air pressure injected to move the), the fine adjustment operation of the opening and closing operation valve is difficult, and in the case of the emergency difficult to provide the air pressure is not provided with a separate means for opening and closing control has a problem that opening and closing adjustment is difficult. do.

Furthermore, the opening and closing operation side 20 may cause smooth operation due to friction with the inner circumferential surface during the reciprocating movement operation on the inner flow path 13.

In addition, the opening and closing valve is located in the outside of the flow path 13 in the process that the fluid flowing through the inner flow path (l3) is guided through the curved guide groove (13c) of the flow path 13 and transported. The fluid is transported relatively quickly through the curved guide groove 13c, but the fluid located inside thereof requires a frictional force with the disk 30 and a process of guiding the guide groove 13c, so that the fluid is quickly There is a problem that does not provide a smooth movement.

The present invention has been made to solve the problems that the prior art has as described above has the following object.

A preferred embodiment for achieving the above object of the present invention will be described in detail with reference to the accompanying drawings.

That is, the present invention, as shown in Figures 3 to 5, the inlet hole (13a) and the outlet hole (13b) and the outlet to both sides in the main body 10 coupled to the left and right partitions (11, 12) Opening and closing operation side to form an inner flow passage 13 having a curved guide groove 13c toward the ball 13b side, and to form a distribution hole 21 in the center of the inner flow passage 13 ( 20 is installed to reciprocate a certain distance, and the inside of the guide groove (13c) by installing a disk 30 in the pneumatic chamber through the opening, closing the pneumatic injection hole (16a) (6b) of the main body (10) Since the air pressure injected into the (l5a) (15b) pressurizes and moves the pressurizing actuating protrusion 25 of the opening / closing operation side 20, the front end pressurizes or spaces the disk 30 to open or close the inner flow passage 13. To be

The disk 30 is assembled to install the guide bar 45 coupled to the rotating body 40 to form a plurality of inclined blades 42 forming a twisted inclined state on the inlet side,

The opening and closing operation side 20 forms an adjustment groove 26 in the center of the pressurizing operation protrusion 25 ′ having a wide contact area, and an assembly groove of the main body 10 as an upper center of the adjustment groove 26. Insert the control rod 52 of the control lever 50 is installed rotatably assembled to the (27), the control rod 52 is installed at a predetermined angle on the horizontal line on the outer periphery of the control lever 50 of the control lever 50 The opening and closing operation side 20 is made to move by the same distance in the same moving direction with respect to the rotating direction and the rotating movement distance.

At this time, the adjustment lever 50 is inserted into the support rod 53 to prevent the flow of the lever while contacting the pressing operation projection (25 ') during the rotation operation of the control lever 50 in one position of the control rod (52). Done.

In addition, the opening / closing operation side 20 is supported by the elastic springs 63 at equal intervals on the outer periphery of the front and rear as shown in FIG. Is provided with an elastic support means 60 to adjust the elastic force by the adjustment bolt 64 screwed to the bearing case 65 of the outer side.

In addition, the disk 30 is formed in the form of a single or assembly inclined guide portion 34 inclined in the inner circumferential direction to guide the flow of the fluid, the inclined guide portion 34 is shown in FIG. As described above, the concave surface 34a, the flat surface 34b, and the convex surfaces 34c and 34d can be implemented in various ways.

As shown in the diagram of FIG. 9, the inclined guide part 34 may have a different flow coefficient for each opening, and may be selectively used depending on the amount of fluid to be transferred from the pipe to which the valve of the present invention is applied. For example, in the state where 50% is opened, the flow coefficient of the concave surface 34a is about 80%, the flow coefficient of the plane 34b is about 50%, and the flow coefficient of the convex surface 34c is about 35%, Since the flow coefficient of the convex surface 34d forms about 20%, the inclined guide portion 34 is more convex than the concave shape, so the amount of fluid to be transferred increases.

In addition, the present invention is to prevent the oxidation due to the contact of the fluid by the Teflon coating process to the contact area with the fluid while passing through the fluid.

As the reference numerals, 5 denotes a packing member, 7 denotes a fastening bolt, and 9 denotes a Teflon ring.

Looking at the operating relationship of the present invention configured as described above, first, in the operation of opening the valve, as shown in Figure 3 when the air pressure is injected into the open air pressure injection hole (15a) of the main body 10 is the air pressure chamber (6a) Pressurizes the pressing operation projection 25 'of the opening and closing operation side 20 toward the inlet hole (13a) to move through.

At this time, the pressure actuating projection 25 ′ smoothly moves because it forms a wide contact area with the inner surface of the main body 10 to prevent flow.

As described above, the opening and closing operation side 20 moving toward the inlet hole 13a is spaced apart from the disk 30 by the opening and closing surface 22 at the tip thereof to open the flow path 13.

In this way, while the opening and closing operation side 20 opens between the disk 30 and the fluid introduced through the inlet portion l3a and the inner flow passage 13, the fluid guide groove 13c on the flow passage 13 is connected to the curved guide groove 13c. Guided to be continuously conveyed through the through hole 31 and the outlet hole (13b) of the disk (30).

At this time, the fluid has a centrifugal force in the outward direction while passing through the twist-type rotary blade 42 of the rotating body 40 installed on the inlet (13a) side of course

Guided to the guide bar 45 provided on the inner flow path 13 to move the inner flow path 13 quickly, and also to guide the inclination of the disk 30 located on the inner side of the outlet (13b) side Since the frictional resistance with the part 34 is minimized, it is easily moved through the guide groove l3c.

In addition, as described above, the inclined guide portion 34 of the disc 30 selectively applies the concave surface 34a, the flat surface 34b, and the convex surface 34c, 34d according to the fluid transfer amount of the valve. It is possible to more effectively control the transport of fluid and the like.

As a result, the fluid passing through the inner passage 13 can be easily and quickly moved to pass through.

In addition, during the closing operation of the valve as shown in Figure 4 when the air pressure is injected through the closed air pressure injection hole (16b) to pressurize the pressing operation projection (25 ') of the opening and closing operation valve 20 opening and closing operation As the side 20 moves to the opposite exit hole 13b side, the opening and closing surface 22 at the front end of the disk 30 presses the disk 30 to close the flow path 13.

In this way, the opening and closing operation side 20 is closed between the disk 30, so that the fluid flowing through the inlet 13a and the inner passage 13 is no longer the through hole 31 and the outlet of the disk 30 Will not be transported through the ball (13b) is to block the flow of the fluid.

In addition, when the opening and closing operation of the valve described above, the opening and closing operation side 20 is elastically supported by the pneumatic spring 63 by the plunge 62, as shown in FIG. Since the frictional force between the opening and closing operation side 20 and the inner circumferential surface of the inner flow path 13 during the movement operation of the opening and closing operation side 20 by the air pressure is to provide the opening and closing operation more smoothly.

At this time, the elastic force of the plunge 62 is to be adjusted by adjusting the adjustment bolt 64 on the bearing case 65, so that it is possible to control the movement of the opening and closing operation valve 20 according to the air pressure.

In addition, the opening and closing valve of the present invention is to rotate the control lever 50 in the open or closed direction, as shown in Figure 6, when fine adjustment of the opening and closing operation valve 20 or when the air pressure can not be supplied in emergency When the control rod 52 of the control lever 50 is rotated about the control lever 50 by the control rod 52 is guided along the adjustment groove 26 of the opening and closing operation valve 20, opening and closing operation The side 20 is moved by pressing in the direction of rotation.

At this time, the moving distance of the opening and closing operation side 20 is determined according to the rotational moving distance of the control rod 52 by the control lever 50.

In addition, the control lever 50 is provided with a support rod 53 on one side of the control rod 52 to prevent the flow of the control lever (50 ') while in contact with the pressure actuating projection (25') during the rotation operation of the control lever ( 50) accurate operation is possible.

In addition, the control lever 50 is a manual lever by the lever (LEVER) and the override handwheel (OVERRIDE HAND WHEEL), as well as the position of the position proximity contact (LIMITS) SWITCH) and proximity sensor are used to enable accurate and precise operation.

Meanwhile, the present invention can be implemented differently as shown in the accompanying drawings, FIGS. 10 to 12. In FIG. 10, the guide bar 45 and the rotating body 40 are excluded from one side of the disk 30. The opening and closing operation side 20 simply shows a simple structure that is used to control the opening and closing of the flow of fluid, such as pressurized or spaced disk 30, the operation relationship is the same as the above-described preferred embodiment.

In addition, in Figure 11 as another embodiment of the manual operation of the opening and closing operation valve 20, the operating hole (26 ') is formed on the pressing operation projection (25') of the opening and closing operation valve 20, and adjusted on the upper Inserting the adjusting rod 57, which is assembled on one side of the lever 56, through the long hole 17 formed on the main body 10, the other side of the adjusting lever 56 is fixedly installed on the hinge shaft 58 that rotates. By rotating the hinge shaft 58 in the opening or closing direction of the valve, the control lever 56 rotates the hinge shaft 58 to the point, and the adjusting rod 57 is guided to the long hole 17. The opening and closing operation 20 is to be adjusted in the opening direction or the closing direction, the opening and closing operation is the same as the above-described preferred embodiment.

In addition, in FIG. 12 is a fluid line in each of the open and closed pneumatic injection holes 16a and 16b as another embodiment of the operation of the opening / closing operation valve 20, which is operated hydraulically by a fluid, not pneumatic or mechanical. (71) (72) is connected, and the fluid lines (71) (72) connect the fluid line (73) connected to the inlet (13a) side with a three-way valve (75) to open the inlet ( The fluid on the 13a side is injected into the open air pressure injection hole 16a through the fluid lines 73 and 71, and the pressurized actuating protrusion 25 'of the open / close operating valve 20 is opened in the open direction by the injected fluid. Pressurized operation, on the contrary, in the closing operation of the valve, the fluid on the inlet (13a) side is injected into the closed air injection hole (16b) through the fluid lines (73) (72) to open and close the operation valve ( By pressing the pressing operation projection 25 of the 20 in the closing direction to control the opening and closing of the valve.

This method is to simply control the opening and closing of the valve by the fluid and the like transported in a state in which a separate air pressure is excluded.

In addition, the present invention, as shown in Figure 13, the degree of rotation of the control lever 50 or the hinge shaft 56 rotates in accordance with the opening and closing degree of the opening and closing operation valve 20 in one valve installed on the pipe (T) It detects this and transmits the rotation degree to other valves by actuator, oil, pneumatic, etc., so that many valves can be opened and closed in the same state.
