Abstract

The invention provides a double-circuit electromagnetic valve. The aim of receiving one electric signal for controlling two successive on-off actions can be achieved, so that one medium path of the double-circuit electromagnetic valve is firstly on and then off, and the other medium path is firstly off and then on. The double-circuit electromagnetic valve comprises an electromagnet, a valve body,a valve element I, a valve element II, a pull rope I, a pull rope II and elastic recovery mechanisms, wherein the electromagnet comprises an armature; two valve element installation holes are formed in the valve body; a group of medium runner is arranged at the lower end of each valve element installation hole; the valve element I and the valve element II are respectively arranged in the valve element installation holes; the upper ends of the valve element I and the valve element II are each provided with one group of elastic recovery mechanism; and when the valve element I and the valve element II are applied by elastic forces so as to seal the corresponding medium runners, and the pull rope II is at a tension state, the pull rope I is at a relaxed state.

Description

Technical field [0001] The present invention relates to the technical field of fluid attitude control, and more specifically, to a two-way solenoid valve, which is particularly suitable for use in a small-thrust liquid engine with strong oxidizer and strong corrosive fuel. Background technique [0002] In the field of fluid attitude control technology, the solenoid valve is the key executive component that controls the flow of the medium. The traditional two-way solenoid valve either uses two electrical signals to control two solenoid coils, and then controls the oxidizer and fuel, or uses one electrical signal to control a pilot two-position three-way solenoid valve, through the control of the gas circuit Control the on and off of the gas, drive the piston to drive the valve core to move, and then control the switch of the main valve core to achieve simultaneous control of the oxidizer and fuel. [0003] In some power systems, it is usually necessary to use an electrical signal t...
