Embodiment Construction

[0024] After cutting the diaphragm with a cutter, the design idea of ​​forming a passage inside the cutter, but directly changing the start-up electric explosion valve in the prior art into a large-diameter structure, there is an instantaneous high pressure when the gas and liquid circuits are connected, and the cutting Knife bounces back, blocks again the defect of gas, liquid path, and valve volume increases obviously simultaneously, and negative mass is bigger, and this is the technical problem that must be solved in the design of the present invention. The invention adopts the structural design of the passage formed inside the cutter, and the pressure leaks from the inside of the cutter after starting, which will not cause the rebound of the cutter, and at the same time, the product has a small volume under the requirement of a large diameter.

[0025] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0026] The presen...

Abstract

The invention provides an electric blasting valve. According to the structure of the electric blasting valve, the upper portion of a shell is provided with an end cap, an air path channel and an installation channel vertically penetrate through the inside of the shell and the inside of the end cap, the end cap is the inlet of the electric blasting valve, the lower end of the shell is provided with the outlet of the electric blasting valve, a limiting check ring is arranged on the upper portion of the shell and is limited by the shell, a membrane is arranged above the limiting check ring, cutters are arranged in the shell channels, the insides of the cutters are communicated, and an igniter is connected with the shell. The air path channel is opened in a mode that the membrane is cut by the cutters and can be in serial connection with pipelines, and the electric blasting valve can be applied to air path and liquid path systems with large drift diameters and large flow, can stabilize work and is high in reliability.

Description

technical field [0001] The invention relates to an electric explosion valve, in particular to an electric explosion valve of gas circuit and liquid circuit system, and belongs to the technical fields of gas circuit and oil circuit. Background technique [0002] With the development of modern industry, higher requirements are placed on electric explosion valves. It is required to be able to work stably in large diameter, large flow gas and liquid systems without affecting the overall performance of the system. At present, the start-up electric explosion valve is a reverse pressure-bearing structure, which is mainly composed of a shell, a snap ring, a piston, a diaphragm, etc. Due to its structural limitations, it can only be used in the general diameter and flow range, and cannot be used in Datong It can work stably in gas and liquid systems with large diameter and large flow. Contents of the invention [0003] The purpose of the present invention is to overcome the defi...
