Embodiment 1

[0041] In order to meet the development needs of miniaturization, light weight, and fast response thrust devices of weapon systems such as mobile warheads and interceptors, a single-coil, single-chuck, multi-channel parallel direct-acting device with small structure, light weight and fast response is proposed. Type multi-component solenoid valve program, see figure 1 . The solenoid valve is mainly composed of an electromagnetic drive coil 1, a disc armature 2, a valve body 3, multiple valve stems 4, multiple return sealing springs 5, multiple spring sleeves 6, multiple sets of screw sleeves 7 and multiple O Shaped seal 8 is composed. When the electromagnetic drive coil 1 is not energized, the magnetic poles on the end face do not produce attractive force. Under the action of the force of the reset sealing spring 5 of each path, the valve stem 4 of each path is pressed against the valve seat, and the medium is sealed upstream of the valve port. When the electromagnetic drive co...

Embodiment 2

[0043] The single-coil, single-chuck, multi-channel parallel direct-acting multi-element solenoid valve is the same as in Example 1. For the electromagnetic drive coil of the present invention, see figure 2 , Mainly composed of a coil bobbin 8, an enameled wire 9, a release ring 10 and a wire 11. Its characteristic is that the end surface of the coil bobbin 8 is a magnetic pole. In order to speed up the response performance of the electromagnetic drive coil 1, the 350 turns of enameled wire 9 wound on the coil bobbin 8 of the present invention constitutes an electromagnetic drive coil 1 with a small number of turns and low inductance. A release ring 10 is placed in the middle of the end surface magnetic poles, which protrudes magnetically. The height of the extreme surface is 0.1mm, and the non-working air gap between the pull-in rear disc armature 2 and the end surface magnetic pole of the electromagnetic drive coil 1 is increased, so that the suction force during release will ...

Embodiment 3

[0045] A single-coil, single-chuck, multi-channel parallel direct-acting multi-component solenoid valve is the same as in Example 1-2. For the sealing structure of the multi-channel medium channel of the present invention, see figure 1 , Each medium channel is mainly composed of the valve body 3, the valve stem 4, the return sealing spring 5, the spring sleeve 6 and the O-shaped seal 8. The multi-channel flow channels and the sealing structure are arranged independently and symmetrically on the valve body 3. Among them, the O-shaped seal 8 is installed in the sealing groove of the valve body 3, the valve stem 4 is inserted into the center holes on both sides of the valve body 3, the reset sealing spring 5 is sleeved on the upper part of the valve stem 4, and is screwed into the valve body 3 through the spring sleeve 6. Compress the reset sealing spring 5, and use the valve stem 4 to press on the valve seat to ensure the sealing of the medium passage.

Abstract

The invention discloses a single-coil single-sucker multi-channel parallel-connection direct-action multi-component electromagnetic valve used for a multi-component rocket engine. An electromagnetic driving coil is arranged on the upper portion of a valve body. An operating part and a medium channel part are arranged inside the valve body. Medium channels of all the components are formed in the valve body in a circumferentially symmetric mode. A release ring is arranged in the center of a magnetic pole of the end face of the electromagnetic driving coil, so that a non-working gas gap between an armature and the magnetic pole is guaranteed after the attraction force is increased, and fast release can be achieved easily; all valve rods are connected to step holes of the armature through thread sleeves, and the stroke can be adjusted by rotating threads; all the valve rods are pressed tightly onto a valve seat through reset sealing springs, and it is guaranteed that the medium channels are closed. According to the single-coil single-sucker multi-channel parallel-connection direct-action multi-component electromagnetic valve, a magnetic field is generated by energizing the electromagnetic driving coil, the magnetic pole on the end face of the coil attracts the disc type armature, and the multiple valve rods are pulled to open the medium channels. The direct-action multi-component electromagnetic valve structure is small in coil number, low in structural mass and high in reliability.

Description

Technical field [0001] The invention belongs to the technical field of engines, and relates to an electric control valve for a liquid rocket engine power system. Background technique [0002] The orbital attitude control power system is an important part of the missile weapon. The thrust device is the orbital attitude control power system power device, which is generally composed of a control valve and a thrust chamber. The new mobile penetration warhead technology puts forward lighter and faster requirements for the thrust device control valve; as a high-tech weapon with strategic influence in the new century, the micro kinetic interceptor is the most effective means of anti-satellite and ballistic missile defense today. The control valve is also required to have a small structure, light weight, fast response, and simplify the electrical control system. [0003] The existing direct-acting solenoid valves are generally single-channel. Each thrust device needs to be equipped with t...
