Abstract

The invention provides a micro two-position two-way solenoid valve which is used in a high-pressure environment and is reliable in sealing and light. The two-position two-way solenoid valve comprises a valve body, a coil assembly, a valve element arranged in the valve body, a valve base, a spring applying force to the valve element and an air inlet connector. A polygon and rectangle combined irregular coil window structure is adopted for the coil assembly of the solenoid valve, redundant space in an electromagnet magnetic path is designed into an irregular coil window, the space in the electromagnet magnetic path is fully utilized to achieve the compact structure, the size is reduced, and the mass is reduced. A mushroom-shaped sealing mode with the flat end face and a trapezoidal boss in butt joint is adopted in the valve element and valve base sealing structure; an O-shaped sealing ring, a plastic check ring and a metal gasket are sequentially arranged at the connecting end of the valve base and the valve element to achieve multiple redundant sealing. It is guaranteed that miniaturization design is achieved during safe, reliable and lasting work in the high-pressure environment, and the production cost is greatly reduced.

Description

technical field [0001] The invention relates to a two-position two-way solenoid valve, in particular to a solenoid valve suitable for controlling the on-off of pipelines in a gas supply system in a high-pressure environment. Background technique [0002] Nowadays, the extrusion liquid rocket engine is more and more widely used because of its simple system and reliable operation. The high-pressure gas supply system is an indispensable system for the extrusion liquid rocket engine. One of the important components of the gas supply system, it is used for the on-off control of the gas supply pipeline. A certain type of liquid rocket engine gas supply system needs to be equipped with a miniature high-pressure two-position two-way solenoid valve. The working medium of the high-pressure solenoid valve is air or nitrogen, and it is required to work normally under the pressure of 0-40MPa. The medium is controlled by the high-pressure solenoid valve. circulation and disruption. The ...
