Description

Switch-gear of super high pressure compressed gas}

The present invention relates to an ultra-high pressure compressed gas switchgear, and more particularly, to an ultra-high pressure compressed gas switchgear for leaking the compressed gas for extinguishing by opening the valve automatically and manually in response to the operation signal of the fire monitoring system. In museums, galleries, underground spaces, engine rooms and chemical plants of ships, when a fire occurs, the fire monitoring system operates to generate an alarm sound and the fire extinguishing device operates to compress the high-pressure carbon dioxide or extinguishing gas stored inside the pressure vessel. The gas is injected through the pipe to extinguish the fire.

Such conventional techniques include U.S. Patent Nos. 2,466,750 (named control device) (hereinafter referred to as `` prior art ''). The prior art is schematically made up of a link system consisting of a solenoid, a latch, a support and a spring.

However, this conventional technique is complicated in structure, the locking jaw and the connection is weak, the device is expected to be damaged by severe impact force during operation, the support plate supporting the force of the strong compressed spring is advanced, the thin pressure plate connected to the pressure vessel It is configured to cut, but the end of the support is sharpened so that the cutting edge plate and the cut pressure plate overlaps at the time of cutting, so that a part of the pressure often does not leak out, which is why the fire extinguishing function in case of fire May not perform correctly

Fire damage is increased. In addition, the solenoid operates in the market

There is a device that opens and closes the valve of the compressed gas cylinder by the opening and closing shaft fastened to the rotating shaft, but it is inconvenient to use, and the structure is complicated, causing the cost increase, and the lever that rotates the rotating shaft is weak. There is a case of separation. In addition, it is inconvenient to use because a lot of force is required to rotate the rotating shaft to its original position when restarting. In addition, the method of cutting the pressure plate must be replaced with a new plate when restarting, and the replacement of such consumables brings inconvenience of disassembling and assembling the system.

As described above, it can be said that it is a weak point to dualize the driving part to open the pressure plate of the valve and the driven part to open the high pressure pressure vessel. In addition, Utility Model Registration No. 0232387 secures the above disadvantages, and uses a high-pressure solenoid as a drive unit, and the follower unit has a connection portion connecting the drive unit and the follower by configuring a valve attached to the pressure vessel as the follower unit. . The characteristic is that the pressure valve plate is removed from the driven portion, and the poppet in the driven portion retreats due to the pressure discharged from the driving portion to the atmosphere, so that the gas of the high pressure pressure vessel flows out to the desired place.

After the inventor registered the above No. 0232387 and made a product dozens of experiments and found some problems, the causes are as follows. Since the above design is provided with a connector for connecting the body 10 and the casing 30, the path of the working fluid is lengthened, and the plunger in the cylinder is pressed well while the chattering phenomenon occurs. And leaks of high pressure compressed air at the

Defects and disassembly are complicated problems.

The present invention is to solve the above-mentioned problems, by moving the plunger in accordance with the electrical signal is a small amount of the ultra-high pressure compressed gas existing in the closed space flows out through the instantaneous discharge port. Due to this outflow, the pressure balance inside the device is broken and the piston-type poppet is moved, thereby providing an ultra-high pressure compressed gas switchgear in which a large amount of compressed gas flows out to a desired place through an outlet.

The present invention improves the noise and operation instability caused by chattering by shortening the path of working fluid by maximizing the registered No. 0232387, and controlling the ultra high pressure pressure that is easy to disassemble and assemble. It is to provide a switchgear.

The present invention integrates what was divided into four parts of body, connecting part, casing, and cylinder in Utility Model Registration No. 0232387 into two parts of body and cylinder, thereby fundamentally blocking the problem of ultra high pressure leakage from the connecting part, and instantaneous discharge. By shortening the path, the operating pressure from the poppet is rapidly transmitted to the plunger in the cylinder, thereby preventing the chattering of the plunger and providing an ultra-high pressure compressed gas switchgear to stabilize an unstable operating state.

In order to achieve the above object, the present invention is largely divided and connected to the body 15 with the high pressure gas cylinder 22 as an axis, and is composed of a cylinder 4 and a solenoid 8 thereon. In detail, the inlet 21 is connected to the high-pressure gas cylinder 22, and the body 15 has a spring 17, a poppet 18, an outlet 14, a manually operated valve 11, and a protrusion 9. ) And the instantaneous discharge port 12. Moreover, the inside of a cylinder is comprised with the plunger 7, the spring 6, and the core 3, and the outside is comprised with the solenoid 8 and the cover 2. As shown in FIG.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, in describing the present invention, if a detailed description of a related known function or configuration may obscure the subject matter of the present disclosure, the detailed description thereof will be omitted.

1 is a perspective view showing the ultra-high pressure compressed gas switchgear according to the first embodiment of the present invention, Figure 2 is an exploded perspective view showing the ultra-high pressure compressed gas switchgear according to the first embodiment of the present invention separated . 3 and 4 are cross-sectional views showing the ultra-high pressure gas opening and closing device cut in the center. As shown in Figure 1, the ultra-high pressure gas opening and closing device according to the present invention is the inlet 21 formed in the lower body 15 is connected to the high-pressure gas cylinder 22, the body is a manual operation valve 11, discharge ( 14) and the instantaneous discharge port 12, and the upper part of the body is composed of a solenoid (8), a cover (2) and a screw (1). As shown in FIG. 2, the separated perspective view of FIG. 1 includes a piston-type poppet 18 that opens and closes the discharge portion 14, and a spring 17 that is installed on one side of the poppet. The upper part of the body 15 is configured with a protrusion 9 and an instantaneous outlet 12 through which stagnant ultra-high pressure escapes through a small hole. There is also a cylinder 4 and a solenoid 8 above the upper body, and a core 3, a spring 6 and a plunger 7 inside the cylinder. The manual actuated valve 11 to enable the operation of the other side of the body 15 due to electrical and mechanical defects is impossible in case of the explosion of the high pressure gas cylinder 22 due to external causes. It also has the effect of playing a role. Poppet 18 inside the body of Figure 3 forms an inclined surface on one side and a sealing 10 is bonded to the end surface. In addition, the other side of the poppet is concavely recessed and a spring is inserted.

By the force of the spring, the poppet is in close contact with the protruding portion of the protrusion 20 on one side of the discharge portion 14, thereby preventing the compressed gas from the inlet 21 toward the discharge port 19. Therefore, the high pressure gas in the high pressure gas cylinder 22 flows between the gap between the poppet and the body and flows into the space 16. The introduced compressed gas flows up through the connector 13 and flows into the cylinder 4. Within the cylinder is a core 3, a spring 10 and a plunger 7. The plunger is recessed so that the spring 6 can be inserted in the upper part, and the sealing 10 is attached to the lower part. The upper part of the body has a protrusion 9 is configured to be in close contact with the sealing of the lower plunger (7). Therefore, the ultra-high pressure gas inside the cylinder is caused by the weight of the plunger and the force of the spring loaded on the protrusion 9 connected to the instantaneous discharge port.

Since the bottom surface is in close contact, the flow of gas is blocked. Therefore, by the manually operated valve 11 connected to the protrusion 9, the protrusion 20 and the connector 13, the ultra-high pressure gas is a system that is completely blocked outflow.

Figure 4 is a cross-sectional view of the operating state showing the operating state of the ultra-high pressure gas opening and closing device according to the present invention. As shown in FIG. 4, when the solenoid 8 is powered and operated, the plunger 7 is moved upward by the strong force of the electromagnet to open the hole of the instantaneous discharge port 12. Then, as the compressed gas in the cylinder and the compressed gas in the connector 13 and the space 16 flow out to the outside through the instantaneous discharge port 12, the pressure in the space 16 is lowered. At this time, a small gap between the body 15 and the piston-type poppet 18 serves as an orifice, causing a pressure drop. Therefore, the pressure of the space portion 16 is lowered, and the pressure on the protrusion 20 side is greater than the space portion 16 side, so that the poppet 18 retreats toward the space portion 16 and the passage of the connector 13 Is blocked, and the poppet is separated from the protrusion 20 so that the outlet 19 is opened. When the outlet 19 is opened, the ultra high pressure gas in the high pressure gas cylinder can flow out toward the outlet through the inlet 21.

In addition, the connector 13 has a manual operation valve 11 inside the space 16 and the connector 13 by simply moving the handle of the manual operation valve by the manager when an emergency occurs due to electrical and mechanical defects. High pressure gas in can flow out. Therefore, the pressure of the space 16 decreases due to this outflow. At this time, the body 15 and the piston type gun

The small gap between the pet 18 serves as an orifice, and the pressure of the space 16 drops. Therefore, since the pressure on the side of the protrusion 20 is greater than that of the space 16, the poppet 18 retreats toward the space 16 and the passage of the connector 13 is blocked. At this time, the poppet is separated from the protrusion 20 so that the outlet 19 is opened. When the outlet 19 is opened, the ultra high pressure gas in the high pressure gas cylinder can flow out toward the outlet through the inlet 21.

As described above, the outlet 19 is automatically opened by the manager when the power failure and emergency occurs automatically by the electrical signal, so that the ultra-high pressure gas in the high-pressure gas cylinder can be sent to a desired place.

As described above, the ultra-high pressure compressed gas switchgear according to the present invention is automatically operated by a manager and a manual discharge outlet so that the compressed gas can be quickly moved to a desired place. Compared with the existing products, this product has a simple structure, robust structure, easy disassembly and assembly, no chattering, superior performance, and excellent product reliability. In addition, the present invention can reduce the unit cost of the product because the configuration of the product is simple to reduce the production cost.

In case of using the present invention, if compressed gas for extinguishing is used instead of high pressure gas, initial extinguishing can be performed by supplying compressed gas for extinguishing fire quickly.

It has a great effect in minimizing the lives and property damage caused by fire.
