Equipment opening and shutting superhigh pressure compressed gas with manual opening device}

The present invention relates to an ultra-high pressure compressed gas switchgear having a manual opening mechanism, more specifically, when the operation of the solenoid (solenoid) to automatically open and close the compressed gas by the on-off operation, the operator simply and easily manual compression It relates to an ultra-high pressure compressed gas switchgear having a manual opening mechanism that can open the gas to the outside.

In case of fire in museums, art galleries, underground spaces, ships, factories, and various buildings, a fire detection system operates to generate an alarm sound, while a fire extinguishing device operates to connect high pressure carbon dioxide gas or compressed gas for extinguishing inside a pressure vessel. Spraying puts out the fire.

Here, US Patent US 2466750 has been issued as a technology related to the opening and closing device for opening and closing the pressure vessel in which high-pressure carbon dioxide gas or extinguishing compressed gas is stored, the US Patent US 2466750 was driven by a link method consisting of a solenoid, a latch, a support and a spring. .

However, the US patent US2466750 has a problem that the structure is complicated, the locking jaw and the connection is weak and easily damaged due to severe impact force during operation. In addition, the US patent US2466750 is a thin pressure plate connected to the pressure vessel while the support for supporting the force of the spring is strongly compressed to be cut, the end of the support is sharply formed so that the end of the support and the cut pressure plate In some cases, overlapping pressure discharge to the outside did not occur smoothly. Accordingly, there was a problem that the fire damage is increased due to failure to properly perform a fire extinguishing function.

In addition, the solenoid is operated to rotate the rotating shaft, and the opening and closing device for opening and closing the valve of the compressed gas cylinder coupled to the rotating shaft has been conventionally conceived, but such an opening and closing device was inconvenient to use, the structure is complicated, the manufacturing cost has been increased. In this case, the welding part is separated because the lever that rotates the rotating shaft is weak. In addition, since the pressure plate was cut, it was necessary to replace it with a new pressure plate when restarting, and it was inconvenient because it required disassembly / assembly of the system due to replacement of consumables.

As an improved technology, the inventors of the Republic of Korea Utility Model Registration No. 20-0232387 "high pressure compressed gas switchgear for fire extinguishing", registration number 20-0321512 "ultra high pressure compressed gas switchgear" was devised, the "High pressure compressed gas switchgear for fire extinguishing" and "ultra-high pressure compressed gas switchgear" are operated by solenoid by electric signal to move the plunger so that the ultra-high pressure compressed gas in the sealed space flows to the outside. When the pressure balance is broken, a poppet that opens and closes the gas outlet is moved so that the compressed gas of the compressed gas tank is discharged through the gas outlet.

Such "digestion high pressure compressed gas switchgear" and "ultra high pressure compressed gas switchgear" is a structure that the gas outlet is opened and closed in accordance with the on-off operation of the solenoid by the electrical signal, there is an advantage that no replacement of consumables However, there was a problem in that the power supply is not smooth or inoperable when the electrical circuit is damaged. In particular, in the case of a compressed gas switchgear for extinguishing, there is a problem in that it does not perform a fire extinguishing function for a fire accident and thus aids in a fire accident.
