Double-coil drive air-lock bi-stable electromagnetic auxiliary valve

Abstract

The invention relates to a double-coil drive air-lock bi-stable electromagnetic auxiliary valve which consists of a valve body, an inlet valve seat, a valve core, a spring, an outlet valve seat, a coil A, a coil B, a socket, a gasket, a rubber O-shaped ring and a ventilation nozzle 10. By adopting the double-coil drive air-lock bi-stable electromagnetic auxiliary valve structure, the electromagnetic auxiliary valve can be independently opened and closed by independently and respectively powering the coil A and the coil B, so that the opening and closing response speed of the electromagnetic auxiliary valve can be increased. By adopting the bi-stable design, after the electromagnetic auxiliary valve is electrified for a short time to take relevant action, the electromagnetic auxiliary valve can be powered off and maintained at a stable state after the action, the electromagnetic auxiliary valve can be maintained opening without being continuously electrified, the power consumption can be effectively reduced, the energy-saving advantage is obvious when the electromagnetic auxiliary valve works stably for a long time and multiple electromagnetic auxiliary valves work simultaneously, and the low-energy-consumption design purpose can be easily realized.

Description

technical field [0001] The invention relates to a double-coil-driven air-lock bistable electromagnetic auxiliary valve, which is used in engine control valves, satellite on-orbit execution systems, ground test systems, and automated fluid pipeline systems that require low power consumption and long-range steady-state work. The bistable design can effectively reduce the power consumption of the system, and the double-coil drive design is conducive to improving the response speed of the valve. Background technique [0002] In the development of a terminal attitude control engine, for 4 engine control valves for final speed correction, the design requirements of continuous working time of 95s, low power consumption, and response time of no more than 30ms were proposed. The existing single-coil valve, which is opened when the power is on and closed when the power is off, requires continuous power supply in steady state operation, and the power load is relatively large, which doe...

Problems solved by technology

[0003] In order to solve the technical problem that the power supply load of the existing engine control valve is relatively large and does not meet the requirements of low power consumption, the present invention provides a double-coil-driven air-lock bistable electromagnetic auxiliary valve, which overcomes the shortcomings of the existing technology and structure , the valve is a bistable valve structure in which the air pressure self-locking force keeps it open in the open state and the spring force keeps it closed in the closed state.
