Embodiment 1

[0032] see figure 1 , a quick-opening valve, including a bursting disc 7 and a valve body, as well as an impact rod 4 and a trigger device arranged in the valve body; one end of the valve body is provided with an inlet channel 602 for the detonation agent, and the other end is provided with an inlet channel 602 for the detonation agent Diffusion channel 101, the impact rod 4 is provided with an outflow channel 401 of antiknock agent, the diffusion channel 101 communicates with the inlet channel 602 through the outflow channel 401; the bursting disc 7 is covered on the inlet channel 602, and the impact rod 4 is slidingly connected with the valve body, The impact rod 4 moves toward the bursting disc 7 under the action of the triggering device to pierce the bursting disc 7, so that the inlet channel 602 communicates with the outflow channel 401 .

[0033] The valve body includes a valve upper cover 1, a valve middle section 3 and a valve lower section 6 arranged in sequence; the ...

Embodiment 2

[0047] An explosion suppressor, comprising an explosion suppressant storage tank and a quick-open valve arranged thereon, wherein the quick-open valve applies the quick-open valve in Embodiment 1; the explosion-suppressant storage tank has a flange, and the quick-open valve in the The third stepped hole is sealed and fixedly connected with the flange.

[0048] In order to increase the connection strength between the valve body and the anti-knock agent storage tank, the connection between the lower section of the valve and the anti-knock agent storage tank is full welding.

Abstract

The invention relates to a quick-opening valve and a prepared explosion suppressor applying the quick-opening valve and belongs to the technical field of valves. The quick-opening valve comprises a rupture disk and a valve body and an impact rod and a trigger device which are arranged inside the valve body, wherein one end of the valve body is provided with an inlet passage of an explosion suppressant, the other end of the valve body is provided with a diffusion passage of the explosion suppressant, the rupture disk is arranged on the inlet passage, and the impact rod is provided with an outflow passage of the explosion suppressant, is slidably connected with the valve body and moves to the inlet passage to puncture the rupture disk under the action of the trigger device to make the inletpassage communicate with the outflow passage. According to the quick-opening valve and the prepared explosion suppressor applying the quick-opening valve, by means of the manner that the impact rod ispushed to move to puncture the rupture disk utilizing the trigger device, the problem of poor safety performance existing in existing quick-opening valves is solved.

Description

technical field [0001] The invention belongs to the technical field of valves, and relates to a quick-opening valve and an explosion suppressor prepared by using the same. Background technique [0002] Quick opening valve refers to a valve that can be opened quickly by puncturing the diaphragm. It is used in mines, chemical companies and other environments, and is used in automatic explosion suppression devices to block or suppress flames and explosion propagation. [0003] When combustible gas or dust explodes, the current suppression or blocking method is to quickly spray solid dry powder fire extinguishing agent or liquid fire extinguishing agent through the explosion suppression device. The key technology of the explosion suppression device is a device that can quickly open the explosion suppressor (quick opening valve). [0004] However, the current rapid opening device (quick opening valve) at the outlet of the explosion suppressor has problems such as small opening d...
