Description

Water level control device {DEVICE FOR WATER LEVEL CONTROLLING}

The present invention relates to a water level control device that moves up and down according to the height of water to be filled in a water tank, and supplies or blocks water, and more particularly, when water is filled to a water level set in the water tank, the valve is closed. It is fixed to the water supply is completely shut off, and when the water level is less than the set level, the closed state of the valve is released and relates to a water purification device capable of supplying water.

In general, a water level adjusting device is used in a water tank among piping facilities for the purpose of automatically adjusting the height of water to be filled inside without external power.

The water level control device is mainly used to open the valve so that the buoyant body with buoyancy is installed in the water tank and moves up and down according to the water level and water is supplied, or the valve is closed so that the water supply is cut off at a set level. do.

At this time, the water level control device includes a water level sensor that detects that the water filled in the water tank has reached a set level, and a pump that receives the information detected by the water level sensor and compares and analyzes it with a preset input value to supply water to the water tank.

However, in the conventional water purification level control device, the water surface fluctuates in the process of discharging and supplying water to the set water level, so even when water is filled to the full water level, opening and closing of the valve alternately repeats the supply and shut-off of water in the water tank. It caused a repetitive phenomenon.

In the case of repeating water supply and shut-off, it becomes the main cause of malfunction and failure of the pump as the pump for supplying water must repeat ON/OFF operation. In the case of repeating this supply and shut-off, it increases the fluctuation of the water surface, which shortens the service life of the overall water level control device.

Hereinafter, an apparatus for adjusting a water purification level according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in Figs. 1 and 2, the apparatus for adjusting the water purification level according to an embodiment of the present invention provides a water supply pipe 2 for supplying water into the water tank 1 when the water filled in the water tank 1 reaches a set level. ) Is opened or closed, and the operation of the pump 3 is turned ON/OFF depending on whether the water supply pipe 2 is opened or closed to supply or block water, and the main body 10, the fixing member 20, and It is configured to include the eastern part 30, the sub-sphere 40, and the elastic support part 50.

Here, the water tank 1 includes an electronic water level detection unit 5 that electronically detects the water level of the water tank 1 by sensors installed at two or more different heights, and the water supplied above the full water level overflows and discharges. The overflow water discharge part 6 and the water discharge part 7 formed to use the water stored in the water tank 1 as needed may be provided.

The body 10 is installed at a set height in the water supply pipe 2 inside the water tank 1, and of course, it firmly supports the state in which the fixing member 20 to be described later is installed, and the rotating part 30 is It serves to support it so that it can operate stably when it rotates in the vertical direction.

The fixing member 20 is installed to be fixed to one side under one side of the body 10, and the fixing member 20 at this time is formed to have a length longer than the side width of the body 10 so that the fixing member 20 One side of the body 10 is firmly fixed to the body 10 by a known method such as welding, riveting, screwing, etc., and the other side of the fixing member 20 is preferably installed to protrude from the side of the body 10.

In addition, the fixing member 20 may be installed to be horizontal to the body 10 as shown in the accompanying drawings, but may be installed to be inclined upward or downward at a set angle.

Here, the reason why the other side of the fixing member 20 is installed to protrude from the side of the body 10 is, by increasing the vertical rotation range of the rotating part 30 to be described later, the subsidiary body 40 corresponds to the set full or low water level. It is intended to be able to ascend and descend to height.

The rotating part 30 is installed in a plurality of joint structures so that the upper one side of the body 10 and the other side of the fixing member 20 can be connected to each other to rotate in the vertical direction, and such a rotating part 30 is The water supply pipe 2 is formed to be closed or opened as it rotates upward or downward to the set position.

The rotating part 30 at this time is composed of a rotating inner member 31, a rotating inner piece 32, a support member 33, an opening/closing member 34, a connecting member 35, and an opening/closing valve 36. desirable.

The rotating inner member 31 is installed to be rotated up and down around the rotating shaft 31a on the other side of the fixing member 20, and the rotating inner member 31 has a rotating shaft 31a as shown in the accompanying drawings. It may be formed in a shape bent at a certain angle based on the installation point, and unlike this, it may be formed in a straight line, curved or zigzag shape.

The rotational inner piece 32 is installed to protrude toward the subsphere 40 on one side of the rotational inner member 31, and the rotational inner piece 32 is installed upward or downward based on the rotational shaft 31a. However, as shown in the accompanying drawings, in the case where the rotation inner member 31 is bent, it is installed on one side of the rotation inner member 31 to reinforce the strength of the rotation inner member 31, and the elastic support part It is desirable not only to smoothly rotate by 50, but also to stably fix the rotated state beyond the critical point.

The support member 33 is installed to rotate up and down around the support shaft 33a at the lower end of the rotating inner member 31, and a subsidiary body 40 is installed at the end, such a support member 33 Even if the position of the subsphere 40 is moved up and down within a certain section due to the fluctuation of the water surface, the inner part 31 does not rotate, so that the entire pivot 30 is minimally affected by the fluctuation of the water surface. It is possible to receive.

The opening/closing member 34 is installed to be rotated vertically around the opening/closing shaft 34a on one upper side of the body 10.

The connecting member 35 is installed so that the opening and closing member 34 and the rotating inner member 31 are connected to each other so that the opening and closing member 34 can be rotated in the vertical direction in connection with the rotational motion of the rotating inner member 31. It was formed to be.

The opening/closing valve 36 is installed on one side of the body 10 so as to rotate together with the opening/closing shaft 34a, and when rotating upward based on the critical point at which the tensile force of the elastic support 50 is maximized, the water supply pipe ( It is formed to close 2) and open the water supply pipe (2) when rotating downward based on the critical point.

The floating body 40 is formed to be floated on the water surface by buoyancy and installed in the rotating part 30, and is raised or lowered to a height corresponding to the water level in the water tank 1 by buoyancy, and the elevation In conjunction with the operation, the rotation unit 30 is installed to rotate in the vertical direction.

It is preferable that the weight of the subsphere 40 is formed to overcome the tensile force of the elastic support part 50 to be described later, which is, when the water level gradually decreases in the full water level, the subsphere 40 corresponds by its own weight. This is to make it possible to descend to the height of the water level.

This reason will be described in detail later, but if the tensile force of the elastic support unit 50 exerts a stronger force than the weight of the subsphere 40, the water level is gradually lowered and the elastic support unit 50 ), the floating body 40 in an elevated state cannot descend, and this is because water cannot be supplied because the water supply pipe 2 cannot be opened anymore in a closed state.

The elastic support part 50 is installed to connect between at least one of the body 10 and the rotating part 30 or the fixing member 20 and the rotating part 30 to exert a tensile force.

When the elastic support part 50 exceeds the set critical point, the rotation part 30 maintains an upwardly rotated state, and the water supply pipe 2 maintains a closed state to block water supply. Conversely, the elastic support part When (50) falls below the set threshold, the rotation unit 30 remains rotated downward, and the water supply pipe 2 remains open so that water can be supplied into the water tank 1 Formed.

At this time, the elastic support 50 is a main rotation limiting spring 51 that exerts a tensile force by installing both ends of the fixing member 20 and the rotating inner piece 32 with the rotation shaft 31a interposed therebetween, and opening and closing It is preferable that both ends are respectively installed on the body 20 and the opening/closing member 34 with the shaft 34a interposed therebetween, and configured with a sub-rotation limiting spring 52 that exerts a tensile force.

Through this, when the rotational part 30 is rotated upward based on the critical point at which the tensile force of each of the main rotation limiting spring 51 and the sub rotation limiting spring 52 is exerted to the maximum, the rotation inner member 31 and the opening and closing member ( The water supply pipe 2 can be kept closed by the opening/closing valve 36 by maintaining the state where 34) is rotated upward, and when the rotating unit 30 rotates downward based on the critical point, the internal member ( 31) and the opening/closing member 34 may maintain a downwardly rotated state so that the water supply pipe 2 is opened by the opening/closing valve 36.

Looking at the effects on the water purification level control device configured as described above is as follows.

When the height of the water filled in the water tank 1 reaches a low water level, as shown in FIG. 3A, the float 40 floats at a height corresponding to the water level in the low water level, and the rotating part 30 is the float 40 It is rotated downward to a height floating on the water surface, and the elastic support part 50 is in a state below the critical point and exerts a tensile force to maintain the pivoting part 30 in a downwardly pivoted state.

In this way, when the rotating part 30 is rotated downward, that is, when the floating body 40 is located at a height below the full water level, the water supply pipe 2 is in an open state, and the pump 3 is turned ON and the water tank ( 1) Water is supplied inside.

When the water supply pipe (2) is opened and the pump (3) is turned on and the water level is gradually filled in the water tank (1), the water level rises, the float body (40) rises to a height corresponding to the water level, The rotating part 30 is rotated upward at an angle corresponding to the height at which the floating body 40 rises, and the upward rotation operation of the floating part 40 and the floating part 30 is a height corresponding to the full water level. It continues until the water tank 1 is filled with water.

When the water tank 1 is filled with water and reaches the full water level, the rotating part 30 reaches a critical point at which the tensile force of the elastic support part 50 is maximized as shown in FIG. 3B, and the rotating part 30 When the critical point is reached, the water supply pipe 2 is still opened and water supply is continued.

Thereafter, when the water filled in the water tank 1 reaches the full water level, as shown in FIG. 3C, the floating body 40 rises to the maximum water level, and the rotating part 30 rises above the critical point of the elastic support part 50. It rotates, and the water supply pipe 2 at this time is in a closed state, and the pump 3 is operated OFF, so that water is no longer supplied into the water tank 1.

Here, the rotation unit 30 maintains the upward rotation state by the tensile force of the elastic support unit 50 until the full water level state is released and the rotation unit 30 rotates to a state below the critical point, so that the water surface in the full water level is Even if the floating body 40 moves up and down due to fluctuations, not only can the water supply pipe 2 be kept closed, but the operation of the pump 3 can be maintained in an OFF state.

In addition, when the water level in the water tank 1 is discharged through the water outlet 7 at the full water level, and the water level decreases, the float 40 gradually descends according to the reduced water level. Since 40) is formed with a weight that is heavier than the tensile force exerted by the elastic support part 50, the water level decreases and as the subsphere 40 descends, the rotation part 30 naturally rotates downward past the critical point.

From the moment the rotation unit 30 rotates downward past the critical point, the water supply pipe 2 is opened, and the pump 3 operates to supply water to the water tank 1 through the water supply pipe 2 do.

At this time, since the pivoting unit 30 rotated downward past the critical point is maintained in a lowered state by the tensile force exerted by the elastic support unit 50, after the pivoting unit 30 rotates downward after passing the critical point, As a result, even if the floating body 40 moves up and down, it is possible to stably maintain the open state of the water supply pipe 2, and the ON operation state of the pump 3 is continuously maintained so that the water tank 1 is stably Water can be supplied.

Looking at this in detail, when the water filled in the water tank 1 is in a low water level, the float 40 is in a state that is lowered to a height corresponding to the low water level, and the inner member 31 is It rotates downward by an angle corresponding to the lowered height, and the connecting member 35 moves forward toward the subsphere 40 by a distance corresponding to the angle at which the upper side of the rotation inner member 31 rotates downward.

In addition, the opening/closing member 34 rotates downward by an angle corresponding to the distance the connecting member 35 has moved forward, and the opening/closing valve 36 rotates the opening/closing shaft 34a by the angle at which the opening/closing member 34 rotates downward. It rotates to the center to open the water supply pipe (2).

Here, the support member 33 rotates around the support shaft 33a in the rotational inner member 31, and the movement of the floating body 40 ascending and descending to a height corresponding to the water level, and the rotational inner member 31 Is adjusted to smoothly rotate to a position corresponding to the elevation of the floating body 40.

Thereafter, when water is filled in the water tank 1 and the water level rises, the height of the float 40 is gradually increased due to buoyancy, and as the float 40 rises, the inner member 31 and the opening and closing member 34 ) Is rotated upwardly around the rotation shaft 31a and the opening/closing shaft 34a, respectively, and when the water level in the water tank 1 reaches full water level, the rotation inner member 31 and the opening/closing member 34 are the main Each of the rotation limiting spring 51 and the sub rotation limiting spring 52 is in a state of upward rotation so as to simultaneously reach a critical point at which the tensile force is maximized.

At this time, since the water supply pipe 2 is open, water is continuously supplied to the water tank 1. When the water supplied to the water supply pipe 2 reaches the full water level, the inner member 31 and the opening and closing member 34, the main rotation limiting spring 51 and the sub rotation limiting spring 52 are rotated upward in excess of each critical point, and the opening/closing valve 36 is the main rotational inner member 31 and the opening/closing member 34 The water supply pipe 2 is closed from the moment when each of the rotation limit spring 51 and the sub rotation limit spring 52 exceeds the critical points.

As such, the rotation inner member 31 and the opening/closing member 34 rotated upward beyond the critical point are rotated upward by the tensile force exerted by the main rotation limit spring 51 and the sub rotation limit spring 52, respectively. Thus, the water supply pipe 2 is maintained in a closed state by the on-off valve 36, and the pump 3 is in an OFF operation state, and water supply to the water tank 1 is cut off.

At this time, the pump 3 is a pressure type pump 3A or a relay contact type pump 3B may be used in order to accurately operate ON / OFF depending on whether the water supply pipe 2 is opened or closed.

The relay contact type pump 3B includes a switch unit 3B-1 installed in the body 10 to rotate clockwise or counterclockwise along an opening/closing shaft 34a, as shown in FIG. 4, and the switch unit (3B-1) is provided with a contact portion (3B-2) installed in the body 10 so as to be in contact or spaced apart according to the rotational position, the rotation portion 30, that is, the opening and closing member 34 is a sub-rotation limiting spring When the switch unit 3B-1 is rotated upward so as to deviate from the critical point of 52, the switch unit 3B-1 contacts the contact unit 3B-2 and operates to supply water to the water supply pipe 2, while the opening/closing member 34 is When the rotation limiting spring 52 rotates downward so as to deviate from the critical point, the switch unit 3B-1 is separated from the contact unit 3B-2, and the water supply is cut off.

As described above, in the case where the pump 3 is a pressure type pump 3A as well as a relay contact type pump 3B, the water supply pipe 2 is accurately opened or closed by the opening/closing valve 36. As ON / OFF operation is performed, water level can be adjusted through accurate water supply control.

As described above, the apparatus for regulating the water purification level according to an embodiment of the present invention maintains a state in which water supply is blocked when water is filled to the set water level in the water tank, thereby stably blocking water supply regardless of whether the water surface fluctuates. In addition, failure and malfunction of the pump 3 can be prevented by allowing the pump 3 to not repeat the ON/OFF operation due to the fluctuation of the water surface.

In addition, as the water supply pipe 2 has a structure in which the opening or closing operation of the water supply pipe 2 can be performed simply and accurately, the cost required for manufacturing and maintenance can be greatly reduced, as well as the reliability of the product can be greatly increased.

Hereinafter, a water purification apparatus according to another embodiment of the present invention will be described.

As shown in FIG. 5, a water purification apparatus according to another embodiment of the present invention includes a support 60, a movable part 70, a buoyancy body 80, and a movable limiting member 90.

Here, since the support body 60 and the buoyancy body 80 correspond to the configurations of the body 10 and the subsidiary body 40 described in the above-described embodiment, a description thereof will be omitted.

However, the buoyancy body 80 is formed with a weight that can overcome the restoring force exerted by the movable limiting member 90.

The movable part 70 is installed to be rotated vertically on one side of the support body 60, and is rotated upward or downward to a set position to close or open the water supply pipe 2.

It is preferable that the movable part 70 includes a main movable member 71, a sub movable member 72, and a casement valve 73.

One side of the main movable member 71 is installed to rotate up and down around the main movable shaft 61a on the support body 60, and the buoyant body 70 is installed on the other side.

One side of the sub-moving member 72 is installed to rotate up and down around the sub-moving shaft 62a on the support body 60, and the other side is rotated around the hinge axis 72b on the main movable member 71. Installed.

At this time, the sub movable shaft 72a is preferably installed on the support body 60 so as to be located below the main movable shaft 71a and closer to the buoyancy body 80 compared to the main movable shaft 71a, which is the main movable member 71 ) And the sub movable member 72 are smoothly rotated, and when the main movable member 71 and the sub movable member 72 are rotated upward or downward, This is to ensure that the state rotated in the direction can be maintained.

The hinged valve 73 is installed to rotate together with the main movable shaft 71a on one side of the support 60, so that the main movable member 71 has a critical point at which the restoring force of the movable limiting member 90 is maximized. If the main movable member 71 rotates downward based on the critical point at which the restoring force of the movable limiting member 90 is maximized, the water supply pipe 2 is closed. It is formed to open.

The movable limiting member 90 has both ends installed on the support 60 and the movable part 70 to exert a restoring force so that the movable part 70 can be rotated at a set angle.

Through this, when the movable part 70 is rotated upward beyond the critical point at which the restoring force of the movable limiting member 90 is maximized, the movable part 70 maintains the upwardly rotated state and the water supply pipe 2 is maintained in a closed state. On the contrary, when the movable part 70 is rotated downward to a state below the critical point at which the restoring force of the movable limiting member 90 is maximized, the movable part 70 maintains the downward-rotated state and the water supply pipe 2 is opened. Will be maintained.

It is preferable that one side of the movable limiting member 90 is installed on the sub movable shaft 72a, and the other side is installed on the main movable member 71 so as to be located between the sub movable shaft 72a and the hinge shaft 72b, This is because the main movable member 71 rotated upward or downward by the restoring force of the movable limiting member 90 can be stably maintained in the rotated direction.

At this time, the movable limiting member 90 is preferably made of either a compression spring or a gas shock absorber capable of exerting a restoring force out of a critical point at which restoring force is maximized.

It will be described the effect of the water purification apparatus according to another embodiment of the present invention having the above configuration.

When the water filled in the water tank 1 reaches a low water level, the buoyancy body 80 is in a state that descends to a height corresponding to the low water level as shown in FIG. 6A, and the movable part 70 is the height corresponding to the buoyancy body 80 At this time, the water supply pipe 2 is opened to enable water supply, and the pump 3 is turned ON to supply water into the water tank 1.

When water is filled in the water tank 1 and the water level gradually rises to reach the full water level, the buoyancy body 80 rises to the level of the water level, and the movable part 70 is buoyant. The sieve 80 is rotated upward at an angle corresponding to the raised height to reach a critical point at which the restoring force of the movable limiting member 90 is maximized.

When the movable part 70 reaches the critical point of the movable limiting member 90, the water supply pipe 2 is still open, and the pump 3 is in the ON operation state, so that the water supply into the water tank 1 is continued. .

Thereafter, when the water tank 1 reaches the full water level, the movable part 70 is rotated upward beyond the critical point of the movable limiting member 90 by the buoyant body 80 that has risen to a height corresponding to the full water level. The movable part 70 rotated upwardly in excess is maintained in a state rotated upward by the restoring force exerted by the movable limiting member 90.

In addition, the water supply pipe 2 is closed from the moment when the movable part 70 rotates upward beyond the critical point of the movable limiting member 90, and the pump 3 is in an OFF operation state.

On the other hand, when the water level in the water tank 1 is discharged at the full water level and the water level decreases, the buoyancy body 80 gradually descends as shown in FIG. 6C, and the movable part 70 descends as the buoyancy body 80 descends. As the buoyancy body 80 at this time is formed with a weight that can overcome the restoring force of the movable limiting member 90, it is maintained to rotate upward by the restoring force of the movable limiting member 90 at a height corresponding to the full water level. Not only can the state that is being released, but also can rotate downward past the critical point at which the restoring force of the movable limiting member 90 is maximized.

Here, the movable part 70 rotated downward past the critical point of the movable limiting member 90 is maintained in a downwardly rotated state by the restoring force exerted by the movable limiting member 90 again.

To explain this in detail, when water is supplied to the water tank 1 in a low water level and the water level gradually rises, the buoyancy body 80 gradually rises as the water level rises, and the main movable member 71 The body 80 is rotated upwardly around the main movable shaft 71a at an angle corresponding to the rising height, and the sub movable member 72 is a main movable member by the sub movable shaft 62a and the hinge shaft 72b. It turns upward with (71).

At this time, when the water filled in the water tank 1 reaches full water level, the main movable member 71 and the sub movable member 72 reach a critical point at which the restoring force of the movable limiting member 90 is maximized. , In this state, the water supply pipe 2 is open, and the pump 3 is also in a state of ON operation to supply water into the water tank 1.

Thereafter, when the water filled in the water tank 1 reaches the full water level, the main movable member 71 and the sub movable member 72 rotate upward to a height that exceeds the critical point at which the restoring force of the movable limiting member 90 is maximized. In this case, the hinged valve 73 closes the water supply pipe 2 from the moment the main movable member 71 exceeds the above threshold, and the pump 3 is operated OFF to block the water supply.

Here, the main movable member 71 maintains a state of upward rotation by the restoring force exerted by the movable limiting member 90 unless the buoyant body 80 moves downward so that the main movable member 71 rotates downward beyond the critical point. do.

Accordingly, even if the buoyant body 80 moves up and down due to the fluctuation of the water surface in the full water level state, the water supply pipe 2 is the opening valve 73 by the main movable member 71 that maintains the upward rotational state. ), the closed state is maintained, and the pump 3 can be kept in an OFF operating state.

Conversely, when the water level decreases in the full water level and the buoyancy body 80 descends, the main movable member 71 and the sub movable member 72 are rotated downward below the critical point of the movable limiting member 90, and the movable limiting member ( The downwardly rotated state is maintained by the restoring force exerted by 90), and the opening valve 73 maintains the water supply pipe 2 in an open state by the main movable member 71 which is maintained in such a downwardly rotated state. , The pump 3 is able to maintain the ON operation state again.

Here, as shown in Figure 7, the main movable member 71 has a rotating body 74 that is rotated up and down by a rotating shaft 74a, and a buoyant body 80 is provided at the end of the rotating body 74. It is installed, the movement of the buoyancy body 80 ascending and descending according to the water level, and the movement of the main movable member 71 and the sub movable member 72 to a position corresponding to the lifting height of the buoyancy body 80 It is desirable to make it smooth.

Even at this time, the pump 3 may be a pressure pump 3A or a relay contact pump 3B.

First, when the pressure pump 3A is formed, water is supplied or blocked as the pressure in the water supply pipe 2 changes while the opening and closing valve 63 opens and closes the water supply pipe 2.

Next, when formed with a relay contact pump (3B), the switch part (3B-1) installed to rotate clockwise or counterclockwise along the main movable shaft (71a) inside the support body (60), and installed on the support body (60). When the movable part 70 is rotated upward so as to deviate from the critical point of the movable limiting member 90, including the contact part 3B-2, which is turned ON/OFF depending on whether it is in contact with the switch part 3B-1, the switch When the part 3B-1 and the contact part 3B-2 are kept in contact with each other to supply water to the water supply pipe 2, the switch is turned ON. The part 3B-1 is operated OFF by maintaining the state separated from the contact part 3B-2.

As described above, the water purification level control device according to another embodiment of the present invention prevents the water supply pipe 2 from being opened and closed repeatedly or the pump 3 does not repeat the ON/OFF operation even if a fluctuation occurs on the water surface filled in the water tank 1. , A state in which water is supplied or a state in which water supply is blocked can be stably maintained, and there is an effect of preventing failure and malfunction of the pump 3 as well as the water purification level control device through this.

In addition, as the water supply pipe 2 has a structure in which the opening or closing operation of the water supply pipe 2 can be performed simply and accurately, the cost required for manufacturing and maintenance is greatly reduced, and the reliability of the product can be greatly increased.
