Embodiment Construction
[0012] Below in conjunction with accompanying drawing, the present invention is described in detail.
[0013] In order to make the object, technical solution and advantages of the present invention clearer, the technology of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0014] like figure 1 and 2 As shown, a high-speed release valve for explosion suppression and fire extinguishing includes a valve body 1 and a gas generator 2, and the valve body 1 is provided with a fire extinguishing agent inlet 3 and a fire extinguishing agent outlet 4, and the fire extinguishing agent inlet 3 and the fire extinguishing agent The outlet 4 is coaxially arranged to improve the spraying speed and smoothness of the fire extinguishing agent in the valve body. A p...

The invention discloses an explosion-suppressing fire-extinguishing high-speed release valve. The release valve comprises a valve body and a gas generator, the valve body is provided with a fire extinguishing agent inlet and a fire extinguishing agent outlet which are coaxially arranged, a flow path of the valve body is internally provided with a piston cavity and a fire extinguishing agent channel for being communicated with the fire extinguishing agent inlet and the fire extinguishing agent outlet, a piston is arranged in the piston cavity and connected with a valve plate arranged at a valveopening in the valve body through a piston rod, springs are arranged among the outer circumference of the piston rod, the valve plate and the valve body, the valve plate is pressed at the valve opening in the valve body under the action of the springs, and the gas generator is communicated with an upper chamber of the piston in the piston cavity through an air inlet hole formed in the valve body.By means of the explosion-suppressing fire-extinguishing high-speed release valve, existing conventional fire-fighting equipment can achieve a millisecond-level response, and the problems are bettersolved that the response time of the conventional fire-fighting equipment is long, and explosion suppressing and fire extinguishing cannot be conducted in the initial stage of combustion and explosion.
Description
technical field [0001] The invention belongs to the technical field of fire safety, in particular to a high-speed release valve for explosion suppression and fire extinguishing. Background technique [0002] Scientific research shows that combustible gas explosion is a typical transient process, and the explosion pressure wave front and flame are coupled with each other, and there is a development process from weak to strong, that is, from deflagration to detonation (DDT process). In the early stage of the explosion, not only the low speed propagation of the deflagration flame is low (the initial propagation speed is less than 40 m / s), but also there is a gap between the explosion pressure wave front and the flame propagation surface in the initial stage of the combustion explosion, and the development is relatively slow. With the continuous progress of the DDT process, once the distance between them disappears, a strong explosion (detonation) is formed. At this time, any me...
