Active-and-passive dual-mode instant pressure energy storage unsealing device

Abstract

The invention discloses an active-and-passive dual-mode instant pressure energy storage unsealing device. According to the device, unsealing and opening of an air flow channel within 15 ms can be realized by means of explosion type external force, opening of the channel within 5 ms can also be realized by means of electric signal starting, active and passive dual-mode millisecond unsealing is integrated, energy storage pressure is released, and the device has wide popularization and application values. A high-pressure gas tank is transversely arranged in an explosion suppression medium storage cavity, a diaphragm is arranged at a gas outlet of the high-pressure gas tank, a medium outlet of the explosion suppression medium storage cavity is sleeved with a cover body, the cover body covers the diaphragm, a firing pin is transversely arranged on the front side of the diaphragm, a gap is reserved between the firing pin and the diaphragm, a diaphragm seat is arranged on the outer side of a gas outlet of the high-pressure gas tank, an electronic trigger is obliquely arranged on the diaphragm seat, the trigger end of the electronic trigger faces one side of the diaphragm, the electronic trigger can be in signal connection with an external control end in a wired or wireless communication mode, and the external control end controls the electronic trigger to act to damage the diaphragm.

Description

technical field [0001] The present invention is an active-passive dual-mode instantaneous pressure energy storage unsealing device, which is suitable for use in places where flow passages such as pressure storage containers and fluid pipelines are opened in milliseconds at the millisecond level, especially for safety protection fields such as high-speed opening and rapid suppression of explosions. use. Background technique [0002] At present, whether it is natural gas, gas, coal bed methane, hydrogen, combustible dust, chemical gas and other flammable and explosive media pipelines, there are potential explosion hazards. In order to effectively control the explosion, it is necessary to release the fire extinguishing medium instantly, thereby realizing fire suppression and explosion suppression. security protection needs. [0003] Existing explosion protection mostly uses dry flame arresters, explosion vents, anti-tempering, explosion suppression devices, explosion isolation...

AI Technical Summary

Problems solved by technology

[0004] 1. At present, the opening time of solenoid valve products, especially the valves larger than DN25, is at the second level, and the high-speed solenoid valve is also close to 100 milliseconds. The speed is relatively slow, and the suppression against explosion will fail

[0005] 2. At present, there are mechanical structures that use external impact force to realize the displacement of the mechanical structure to realize the pressure release of the internal pressure storage energy storage, but once there is no external pressure to push, the device will be in a failure state

For example, the automatic explosion-proof device can be activated passively when the shock wave is generated by the explosion, but it cannot be activated automatically when a burning fire occurs, nor can it be activated remotely
