Embodiment Construction

[0013] In order to gain a deep understanding of the structure of pyrotechnic blasting valves, combined with Figure 1 to Figure 6 described as follows:

[0014] The pyrotechnic blasting valve includes a valve body 1 and a valve cover 11. The valve cover 11 is arranged on the upper end surface of the valve body 1. There are left and right horizontal through holes in the valve body 1. The left and right horizontal through holes are divided into left and right parts. , the left part is the inlet pipe a of the valve body, and the right part is the outlet pipe b of the valve body; there is a through hole c in the vertical direction in the valve body 1, and the through hole c in the vertical direction is located above the outlet pipe b of the valve body and is connected with the valve body The body outlet pipe b communicates with the valve body 1, and a piston is arranged in the through hole c in the vertical direction. The piston is convex, including the protruding end 6 and the cy...

Abstract

The invention relates to a firer explosion valve, in particular to a safety device which completes flow channel communication through powder bursting force. The firer explosion valve comprises a valve body and a valve cover. An up-down vertical-direction through hole is formed in the valve body. A piston is arranged along the up-down vertical-direction through hole downwards. A protruding end of the piston extends into a valve body outlet pipeline. The piston is connected with the valve cover through a pulling force bolt. An explosion unit is arranged in the valve cover and is communicated with the up-down vertical-direction through hole above the piston. A shearing cap is arranged in a valve body inlet pipeline. A cap body of the shearing cap is a hollow pipe. A cap top cover of the shearing cap is matched with the valve body inlet pipeline and extends into the valve body outlet pipeline. The cap top cover is arranged below the protruding end of the piston. The valve body, the valve cover and the piston are fixed pieces, and the explosion unit, the pulling force bolt, the buffering device and the shearing cap are replacing pieces. After action is completed each time, the fixed pieces need to be detected, if the fixed pieces are qualified, the qualified replacing pieces are used by replacing, and then the explosion valve can be repeatedly used.

Description

technical field [0001] The invention relates to a pyrotechnic blasting valve, in particular to a safety device which utilizes the blasting force of propellant to complete flow channel communication. Background technique [0002] The blasting valve is a new type of valve, which is completely different from the conventional gate, cut-off, and stop structure and principle. The blasting valve is mainly composed of a valve body and a blasting unit. The main parts are valve body, valve cover, piston, shear Caps, lag bolts, cartridges, igniters, etc. The control unit provides the minimum full ignition current intensity to the igniter, ignites the propellant, and the propellant quickly generates gas, which generates pressure in the middle cavity of the valve body, pulls off the tension bolt, and the piston accelerates and impacts to shear the shear cap and open the valve. Due to the increased flow requirements of the valve in some working conditions, the existing blasting va...
