Abstract

The invention discloses a non-electrical explosion transmission redundant control chip-free high-reliability electric explosion isolation valve. The isolation valve is composed of a valve body, a nozzle, a retaining ring, a piston, a retaining ring, a rubber O-ring, and a cutter. Before detonation, the sealing part of the electric explosion isolation valve isolates the medium in the gas cylinder from the downstream passage; after receiving the system opening command, the non-electric detonation system detonates and generates high-pressure and high-temperature gas and shock waves to act on the piston, pushing the cutter to line the sealing part. Sleeves are cut to open the media and downstream pathways. The invention improves the working reliability of the valve through the redundant structural design of the double initiation device; adopts the single-side positioning structure at the rear end of the cutter to prevent the metal shavings from entering the downstream system, realizes the miniaturization of the valve and improves the reliability of the system; The non-electric explosion transmission system reduces the system power load and improves the valve opening synchronization.

Description

technical field [0001] The invention relates to an electric explosion isolating valve for a squeeze type liquid rocket engine storage system, in particular to a non-electric transmission explosion electric explosion isolating valve. Background technique [0002] The electric explosion isolation valve is one of the important components of the extrusion liquid rocket engine. With the continuous development of aerospace technology at home and abroad, in order to realize the miniaturization of the weapon system and save space size, the requirements for miniaturization, high performance and high reliability of each functional component are put forward. In the development of previous models, the electric explosion isolation valve usually adopts a single electric squib drive structure. When the medium passage is opened, a small amount of metal shavings may enter the downstream system and cause safety hazards. It brings a large load and is not suitable for the miniaturization and h...
