Embodiment Construction

[0034] The following is attached figure 1 A preferred embodiment of the present invention will be described in detail.

[0035] Such as figure 1 As shown, the single-coil miniaturized self-unloading double-component solenoid valve structure of the present invention consists of valve body A3, adjusting gasket 2, valve body B1, coil 4, spring 5, disc spring 7, valve core 8 , Rubber seal 9, rubber O-ring 10, A medium inlet channel 6, B medium inlet channel 12 and so on. The A medium inlet passage is arranged on the valve body A3, and the B medium inlet passage is arranged on the valve body B1. A medium inlet channel and B medium inlet channel are respectively located at both ends of the valve core and are coaxial with the valve core; In body A3, the spool includes a sealing surface A81 and a sealing surface B82. The sealing surface B82 is set on the end surface of the front section of the spool. The sealing surface B82 and the valve body B1 are sealed by a conical surface. Th...

Abstract

The invention discloses a mono-coil miniaturized self-unloading type two-component electromagnetic valve structure. The mono-coil miniaturized self-unloading type two-component electromagnetic valve structure is composed of a base body (an integrated valve body), a valve element, a spring, a coil, a gasket, a magnetic isolation pad, rubber O-shaped rings and the like. The electromagnetic valve is used for controlling startup and shutdown of an engine. Through the optimal matching design of the sealing positions of two-channel propulsive agents, self-unloading is achieved through a coaxial valve element by means of the mutual differences of the two-channel propulsive agents in the directions of medium force on the valve element, the carrying capacity caused by the medium force can be substantially reduced, and it is beneficial to reduce driving loads of an electromagnet and achieve the quick-response design of the valve. According to the electromagnetic valve structure, the two-channel valve element and the unloading structure are highly integrated and the mono-coil drives two-channel supply so that the miniaturization degree of the two-component control valve can be greatly improved. The pressure adaptive capacity of the valve is greatly improved through the self-unloading structure, the improvement of the high-pressure adaptive capacity of the valve based on the theory also becomes very easy, and a new pressure working condition can be adapted only by matching the spring force with the working pressure.

Description

technical field [0001] The invention relates to a self-unloading double-component electromagnetic valve structure. Background technique [0002] In the development of the final attitude control engine for a certain type of weapon, aiming at the engine control valve for a certain medium-thrust level final speed correction, a low power, no drive circuit, miniaturization, high pressure (7MPa), and a response time of no more than 5ms were proposed. design requirements. [0003] The existing two-component fast-response control valve does not meet the system requirements, and its structure has the following characteristics: [0004] 1. Two electromagnetic coils are used to drive the on-off elements of the two medium circuits respectively, and the structure is heavy; [0005] 2. In the field of high-pressure and fast-response applications, in order to achieve unloading, it is necessary to set up unloading structures in the two channels. Many unloading structures bring about the p...
