Description

[0001] DESCRIPTION [0002] VALVE CONTROLLER STRUCTURE FOR SPEED OPEN AND CLOSE [0003]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a valve opening / closing controller capable of rapidly opening and closing a valve in a pipeline through which a high-pressure fluid flows, and more particularly, to a valve opening / closing controller capable of doubling fluid supply and exhausting capacity for opening / closing a valve of a high- Pressure piping valve for rapid opening and closing of the valve so that the valve can be quickly opened and closed.

The conduit for transferring the high-pressure gas is provided with a shielding valve for quickly shutting off the gas supply in preparation for emergency situations.

Since the shielding valve is installed in a large-sized pipe, a large-sized valve should be installed. In order to drive a large-sized valve, the actuator should also have a performance suitable for the valve.

Particularly, in the case of emergency, the actuator installed for shutting off the valve uses compressed air to enable quick operation, and the performance of the controller for rapidly supplying and discharging a large amount of compressed air is very important.

In other words, the opening and closing performance of the valve of the large pipe is determined by the actuator (driving cylinder), and the performance of the actuator is determined by the performance of the controller.

The performance of the controller is determined by the amount of fluid that can be supplied to the actuator per unit time as much as possible and the ability to discharge the fluid supplied to the actuator per unit time.

As a conventional example of such a valve opening / closing controller, in Korean Patent Registration No. 283611, a technique related to a pilot valve-mounted speed controller for controlling the flow rate of a fluid has been proposed.

However, in the above-described conventional art, it is difficult to expand the size of the fluid movement path formed inside the pilot valve constituting the controller, so that the operation of the opening and closing cylinder for opening and closing the valve of the high- It could not be operated quickly.

In other words, it is necessary to prevent the secondary damage by urgently shutting off the supply of gas when an emergency such as fire, leakage or leakage occurs. As the supply of fluid and the exhaustion of the fluid are delayed, If you can not do it quickly, it will lead to an accident that is as long as the delayed time, or it will cause huge economic loss due to gas loss.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above problems of the prior art, and an object of the present invention is to provide a pilot valve for supplying a fluid to a high- So that the high-pressure pipe can be cut off more quickly and precisely.

According to an aspect of the present invention, there is provided a pilot valve for supplying a fluid to a valve cylinder for controlling opening and closing of a high-pressure pipe open / close valve, including: a fluid inlet through which fluid is introduced from the outside; A fluid supply port through which the fluid is supplied to the valve cylinder side via the internal flow path and a fluid exhaust port for discharging the fluid discharged from the valve cylinder side to the outside, Wherein the pilot valve is constituted by a driving piston in which a fluid inlet and a fluid outlet are selectively and reversely driven to communicate with a fluid supply port; An elastic spring for transmitting an elastic pressing force to the driving piston is provided at the front end of the driving piston; A guide passage is formed in the pilot valve for guiding the fluid introduced through the fluid inlet to the rear end of the driving piston so that a forward driving force is applied to the driving piston; The guide passage is characterized in that the solenoid valve controls opening and closing of the passage.

In addition, the inner wall surface of the pilot valve has symmetrical inclined surfaces on both sides of the center to reduce the inner diameter of the central portion as compared with both ends, and a tapered surface is formed on the driving piston so as to make surface contact with the inclined surface. And a packing material for preventing fluid leakage is provided on each of the tapered surfaces of both sides.

The present invention has the effect that the operation of the shielding valve driving cylinder can be performed more quickly by increasing the supply amount of the fluid through the structure change of the pilot valve for supplying and exhausting the fluid from the controller to the valve cylinder side.

Accordingly, since the controller improves the performance, the high-pressure valve can be shut down more quickly in an emergency, thereby reducing the risk of a secondary accident such as fire or explosion.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, a characteristic configuration of a controller for rapidly opening and closing a high-pressure pipe valve according to an embodiment of the present invention will be described with reference to FIGS. 1 to 3. FIG.

The controller in this embodiment has a structure in which a solenoid valve 200 is connected to one side of the pilot valve 100, and controls the supply of fluid to the valve cylinder 300 side.

That is, the pilot valve 100 is provided with a fluid inlet 101 through which fluid (high pressure air, oil, etc.) flows from the outside, and a fluid supplied through the fluid inlet 101 through a valve cylinder 300 and a fluid outlet 103 for discharging the fluid discharged from the valve cylinder 300 side to the outside.

A drive piston 110 is formed in the pilot valve 100 so that the fluid inlet 101 and the fluid outlet 103 are selectively connected to the fluid supply port 102, The elastic spring 120 for transmitting an elastic pressing force to the driving piston 110 is provided at the tip of the solenoid valve 200 and the fluid flowing through the fluid inlet 101 is supplied to the solenoid valve 200 It is confirmed that the guide passage 130 is guided to the rear end of the drive piston 110 by the operation and the forward drive force is applied to the drive piston 110. [

In addition, the inner wall surface of the pilot valve 100 is formed with symmetrical inclined surfaces 104 on both sides with respect to the center thereof so as to have a structure in which the inner diameter of the central portion is reduced as compared with the both end portions, and surface contact is made with the inclined surface 104 The drive piston 110 is provided with a tapered surface 114 symmetrically on both sides thereof and a packing material 115 for preventing fluid leakage is provided on each of the tapered surfaces 114 on both sides.

The fluid inlet 102 is formed at the center of the reduced pilot valve 100 and the fluid inlet 101 and the fluid outlet 103 are formed so that the inner diameter increases with respect to the fluid inlet 102 And the amount of movement of the fluid can be maximized.

The solenoid valve 200 for controlling the opening and closing of the guide passage 130 includes a coil 210 to which power is supplied from a power supply unit 240 and a coil 210 which is wound around the coil 210 And a valve spring 240 for supporting the one end of the moving core 230 with a predetermined elastic force is provided on the outer circumferential surface of the movable core 230 And a feed control seal 231 for opening and closing the channel by contact with the valve body 132 provided at the inlet side of the guide passage 130 is provided at the distal end of the moving core 230, An exhaust guide hole 221 for guiding the exhaust of the fluid supplied to the guide passage 130 is formed in the guide passage 220. The fluid of the guide passage 130 is guided to the exhaust guide hole 221 of the exhaust inducing hole 221, An exhaust control seal 232 is formed which is in contact with the valve body 222 provided on the side of the valve body.

Particularly, the movable core 230 is provided with an inner through hole 235 penetrating the inside of the moving core 230 so that the supply control seal 231 and the exhaust control seal 232 can flow from both sides, A sealing support spring 233 for supporting the supply control seal 231 and the exhaust control seal 232 of the valve body 132 and 222 with a constant elastic force to maintain a stable contact state with the valve bodies 132 and 222, It can be confirmed that the auxiliary exhaust hole 234 is formed at one side of the core 230 so that the fluid can be exhausted quickly and the auxiliary exhaust hole 234 is formed at a position not interfering with the exhaust control seal 232 . That is, in the present invention, the supply control seal 231 and the exhaust control seal 232 can flow in a certain range, and thus the shock generation with the valve bodies 132 and 222 during the up / And a stable watertight state can be maintained due to the elastic action by the seal supporting spring 233. [

The operation and effect of the controller according to the present invention will be described with reference to FIGS. 4 to 9. FIG.

4 and 5, since the fluid supply passage in the pilot valve 100 is connected to the driving piston 110 (see FIG. 4) So that the supply of gas to the high-pressure pipe is blocked.

When the shutoff valve 310 is restored and gas supply is resumed, the valve cylinder 310 is closed by the valve cylinder 310 so that the shutoff valve 310 can be released from the high- 300) side.

6 and 7, when the power is supplied from the power supply unit 250 to the solenoid valve 200, the movable core 230 is lifted up toward the stationary core 220 by an electromagnetic force, The supply control seal 231 blocking the inlet valve body 132 of the guide passage 130 is spaced apart so that the fluid introduced through the fluid inlet port 101 is moved through the guide passage 130, (110) in the forward direction.

Since the fluid inlet 101 communicates with the fluid inlet 102 due to the movement of the driving piston 110, the fluid flowing through the fluid inlet 101 can be quickly discharged through the fluid inlet 102 Pressure piping by the on-off valve 310 so that the supply of gas to the high-pressure pipeline can be resumed.

Particularly, the path from the fluid inlet 101 to the fluid inlet 102 in the pilot valve 100 is formed in the space between the inclined surface 104 and the tapered surface 114 to allow a large amount of fluid movement It can be seen that the shut-off operation of the opening and closing valve 310 can be performed more quickly.

On the other hand, when an urgent situation such as fire, leakage, leakage, or the like occurs and the supply of gas to the high-pressure pipe is to be urgently interrupted, the exhaust drive for cutting off the fluid supply to the valve cylinder 300 side is performed.

8 and 9, when the power supply to the solenoid valve 200 is interrupted, the electromagnetic force is released, and the movable core 230 is moved downward by the elastic force of the valve spring 240 And the fluid supply to the guide passage 130 side is blocked.

The driving force of the driving piston 110 is released and the driving piston 110 is returned to its original position by the elastic force of the resilient spring 120. By the operating pressure of the driving piston 110, The exhaust control seal 232 blocking the valve body 222 is lowered as the gap between the fixed core 22 and the moving core 230 is spaced apart from each other so that the fluid remaining in the main body of the solenoid valve 200 The fluid is moved through the gap between the inner wall surface and the moving core 230, and then exhausted through the exhaust guiding hole 221.

As a result, the fluid supply to the valve cylinder 300 is interrupted and the fluid supply port 102 communicates with the fluid discharge port 103. As a result, The elastic fluid of the elastic body 320 is transmitted to the opening and closing valve 310 so that the working fluid remaining in the valve cylinder 300 is moved in the reverse direction through the fluid supply port 102 and then flows through the fluid outlet 103 It is evident that the emergency shut-off drive of the high-pressure pipe is performed by the action of the elastic body 320 of the opening / closing valve 310. [

Accordingly, when the controller of the present invention is applied, the supply amount of the fluid is increased, so that the operation of the shielding valve driving cylinder can be performed more quickly with the high-pressure pipe.

Although specific embodiments of the present invention have been illustrated and described above, it is obvious that the controller device structure of the present invention can be variously modified by those skilled in the art.

For example, in the above embodiment, one solenoid valve is mounted in the controller. However, as shown in FIG. 10, two or more solenoid valves may be connected through the exhaust port pipe 260 When the plurality of solenoid valves 200 are connected to the pilot valve 100, if an error occurs in the power supply of the first solenoid valve, alternate driving can be performed in the second or third solenoid valve So that the problem caused by the malfunction of the controller can be improved.

Therefore, it should be understood that such modified embodiments should not be individually understood from the technical spirit and scope of the present invention, and such modified embodiments should be included in the appended claims of the present invention.
