Description

[0001] The present invention relates to an ultra-high pressure compressed gas opening / closing apparatus having a lever type manual opening mechanism,

The present invention relates to an ultra-high pressure compressed gas opening and closing apparatus having a lever type manual opening mechanism, and more particularly, to an apparatus for opening and closing an ultra high pressure compressed gas opening / Pressure compressed gas opening / closing apparatus having a lever-type manual opening mechanism capable of manually discharging compressed gas to the outside.

In the event of a fire in a museum, an art gallery, an underground space, a ship, a factory, or a building, a fire detection system is activated to generate an audible alarm, while a fire extinguishing device operates to pressurize the high pressure carbon dioxide gas or digestive compressed gas By spraying, the fire is suppressed.

U.S. Patent No. US2466750 discloses a technique related to an opening and closing apparatus for opening and closing a pressure vessel storing a high-pressure carbon dioxide gas or a compressed gas for extinguishing gas. The US Patent No. 2466750 discloses a method of operating a solenoid, a latch, . However, the U.S. Patent No. US2466750 has a problem in that the structure is complicated and the engagement jaw and the connection portion are weak, so that they are easily damaged due to a severe impact force during operation.

 In addition, US Patent No. 2466750 discloses that a thin pressure plate connected to a pressure vessel is cut while a support for supporting a force of a spring to be strongly compressed is advanced. The end of the support is sharpened so that the end of the support and the cut- It often occurs that the outflow of pressure to the outside is not performed smoothly. Accordingly, there is a problem that the fire damage is increased because the fire extinguishing function can not be performed properly.

 In addition, an open / close device has been conventionally proposed in which a solenoid is operated to rotate a rotary shaft, and an opening / closing shaft engaged with a rotary shaft opens a valve of the compression gas cylinder. However, such an opening / closing device is inconvenient to use, , The lever which rotates the rotary shaft is weak, so that the welding part is separated. In addition, since the pressure plate is cut, it is necessary to disassemble / assemble the system according to the replacement of the consumables.

As a technique for improving this, the inventor of the present invention has proposed a method of using a high-pressure compressed gas opening / closing device of Korean Registered Utility Model No. 20-0232387 entitled " High Pressure Compressed Gas Opening and Closing Device for Fire Extinguishing ", Registered No. 20-0321512, Pressure compressing gas opening and closing device for fire extinguishing, "" ultra-high pressure compressed gas opening and closing device, "and" manual opening device. "However, Gas switching device "is a device in which a plunger is moved by the operation of a solenoid by an electrical signal to cause the ultra-high pressure compressed gas in the closed space to flow out to the outside through the instantaneous discharge port. As a result, So that the plunger of the valve body to be opened and closed moves so that the ultra high-pressure gas of the ultra-high pressure gas tank is discharged through the gas main discharge passage It was made to the configuration.

Since the gas main discharge passage is opened and closed according to the ON / OFF operation of the solenoid by the electrical signal, the above "high pressure compressed gas opening and closing apparatus for fire fighting" and " However, there is a problem that when the power supply is not smooth or the electric circuit is damaged, the operation becomes inoperable state. In particular, in the case of an ultra-high pressure compressed gas opening / closing apparatus, there is a problem that a fire accident can not be performed because the fire extinguishing function can not be performed when a solenoid can not be operated due to a power failure.

In addition, the above-mentioned two utility models and one patented device all discharge a large amount of high-pressure gas to the main discharge path when the plunger of the valve body is moved, and at the same time, a small amount as the "instant discharge port", but the solenoid is turned ON ), The high-pressure gas continues to flow out. Therefore, a small amount of high-pressure gas continuously flows out to the 'instant discharge port', resulting in a decrease in efficiency. Even though a small amount of the high-pressure gas may contaminate the surrounding environment in some cases, it is necessary to compensate.
