Embodiment Construction

[0024] Such as figure 1 with figure 2 As shown, the single-spool dual-channel solenoid valve of the present invention is composed of a valve body 1, a skeleton 2, a coil 3, a disc spring 4, a cylindrical spring 5, a spool 6, and a rubber O-ring 7. The valve core 6 is co-guided with the valve body 1 in the axial direction; the valve body 1 is provided with a first passage 11 and a second passage 12 which are independent of each other, and the first passage 11 includes a first inlet 16 and a first outlet 18 which communicate with each other. The second channel 12 includes a second inlet 17 and a second outlet 19 that communicate with each other; the valve core 6 is a stepped valve core, and the valve body is provided with a first valve seat 13 and a second valve seat 14, and the first valve seat 13 and the second valve seat 14 are arranged on the valve body. After the spool 6 cooperates, the first channel 11 can be sealed; the second valve seat 14 can seal the second channel 1...

Abstract

The invention relates to a single-valve core and double-channel solenoid valve, solving the technical problem that the two channels of the existing solenoid valve can not be easily or synchronously opened and closed, the structure is relatively complex and the weight is heavier. The single-valve core and double-channel solenoid valve comprises a valve body, a valve core and a coil, wherein, the valve core is matched with the valve body for guiding, the valve core generates electromagnetic attraction under the action of the magnetic field of the coil, an axially installed cylindrical spring is arranged between the valve core and the valve body, and a first channel and a second channel which are mutually independent are arranged on the valve body, and the first channel is sealed after a first valve seat is matched with the valve core; the second channel is sealed after a second valve seat is matched with the valve core; and the sealing between the first valve seat and the valve core as well as between the second valve seat and the valve core adopts a combined type soft-hard sealing structure. The invention has the advantages of rapid response, light weight, small volume and good consistency of the action.

Description

technical field [0001] The invention relates to a direct-acting dual-channel electromagnetic valve. Background technique [0002] The dual-component engine is a propulsion device that provides power for the maneuvering flight of various aerospace vehicles. It changes the direction of the aircraft multiple times in space according to the program, and realizes the orbit change and attitude adjustment of the aircraft. The solenoid valve is an important component of the dual-component engine. , used to control multiple starts and pulse work of the engine. Solenoid valves of existing bicomponent engines mainly include direct-acting solenoid valves and electric gas valves. The direct-acting solenoid valve is mainly composed of a single coil and a single spool, and is used to control a single channel. A dual-component engine needs to be controlled by two direct-acting solenoid valves, which increases the number of control circuits and improves the installation efficiency. Difficu...
