Abstract

The invention relates to a propellant gas water hammer cutting electric explosion valve. The purpose is to solve the problems of slow cutting speed, low efficiency and small pressure bearing capacity of the plugging existing in the prior art. The invention comprises a valve body, an adapter cap, an electric squib, and a plug; the side wall of the valve body is provided with a through hole; the electric squib is installed on the side wall of the valve body through the adapter cap; The working end corresponds to the through hole, and its special feature is that it also includes a cover and a diaphragm; a diaphragm is set between the through hole and the working end of the electric squib; the diaphragm is used to isolate the electric squib from the liquid medium; the inside of the valve body Equipped with liquid medium; the selection of the liquid medium requires measures to control the compatibility of the explosive gas of the electric squib tube and the liquid medium to ensure the safety of the product; the cover is installed in the valve body and is located on the left side of the through hole; the blocking cover is installed in the valve body And it is located on the right side of the through hole; the cover body and the blocking cover are both conical components with the small end facing left; a tapered ring cavity is formed between the cover body and the blocking cover, and the tapered ring cavity communicates with the through hole.

Description

technical field [0001] The invention relates to a cutting valve, in particular to a powder gas water impact cutting electric explosion valve. Background technique [0002] The electric explosion valve is one of the important automatic components in various systems of aerospace models, and plays a role in fluid control in the system. [0003] The valve body of the existing electric explosion valve is a gas medium, and the gas medium is pressurized by the explosion impact of the electric explosion tube connected with the inside of the valve body, and the pressurized gas medium cuts through the blocking cover to realize fluid control. However, the existing electric explosion valve has the following problems: [0004] 1. The existing electric explosion valve cuts through the blocking cover through the gas transmission energy. Due to the high compressibility of the gas, the utilization rate of the energy output by the electric explosion tube explosion on the cutting piece is not...
