A Suspension Guidance Support Solenoid Valve

Abstract

The invention relates to a suspension guiding and supporting solenoid valve. The suspension guiding and supporting solenoid valve comprises a filler neck, a cylindrical valve spool, an outer shell, outer armatures, coil springs, a spring, a stop, an insulating layer, O-rings, coils, an inner armature, a shell and a valve seat. The valve spool is fixedly mounted in the filler neck, and provided with through holes communicated with a first cavity of the filler neck; the filler neck is mounted at one end of the outer shell through the shell; the stop is fixed at the other end of the outer shell; the inner and outer armatures, the valve seat, the coil springs and the coils are mounted in an inner cavity of the outer shell, the coil springs are clamped between the inner armature and the outer armatures, and the inner and outer armatures and the valve seat as a whole are suspended and supported in the outer shell through the coil springs; an inner cavity of the valve seat is communicated with an inner cavity of the stop, and can further be communicated or disconnected with the through holes in the valve spool. In the suspension guiding and supporting solenoid valve, the coil springs and armature components are combined into an integrated structure, so that the problems of clamping stagnation and failure of a solenoid valve due to the fact that a conventional guiding and matching pair moves repeatedly to cause wear and clamping stagnation are solved.

Description

technical field [0001] The invention belongs to the technical field of aerospace structures, and in particular relates to a suspension guiding and supporting solenoid valve. Background technique [0002] At present, in the solenoid valve used in the pressurized delivery system of the launch vehicle, when the solenoid valve is energized, the armature overcomes the spring force and the gas pressure of the valve core, and the live valve is separated from the valve seat to form a passage. At present, in order to meet the adjustment times of the gas circuit of the pressurized conveying system, the solenoid valve is required to have sufficient design margin, and its action life must reach more than 10,000 times. Such a long-life solenoid valve is a key technology for the design of the guide, and the traditional guide technology of the mating pair can easily cause the mating pair to wear out and get stuck after multiple movements, which may cause the solenoid valve to get stuck, so...
