Problems solved by technology

[0004] Since the two-position three-way solenoid valve requires the valve stem (core) to work at the two valve ports to ensure the sealing performance of the two valve ports, it has high requirements for machining and assembly accuracy. This problem is often ignored by designers. It has brought great difficulties to the debugging and maintenance of the solenoid valve

Embodiment Construction

[0032] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0033] Such as Figure 1-9 Shown is the structural diagram of the high-voltage, high-reliability, multi-functional two-position three-way solenoid valve of the present invention. It can be seen from the figure that the high-pressure, high-reliability multi-function two-position three-way solenoid valve includes an electromagnet 1, an electromagnet housing 2, a return spring 3, and an armature. 4. Valve body 5, valve stem 6, upper valve seat 7, upper valve port gasket 8, middle valve sleeve 9, lower valve port gasket 10, lower valve seat 11, bottom valve sleeve 12, nut 13, anti-loosening rod 14. Jacking screw 15, adjusting screw 16, positioning pin 17, electromagnet locking bolt 18, spring adjusting pad 19, wire 20.

[0034] Among them, the electromagnet 1 is placed in the electromagnet housing 2 and fixed by the electromagnet locking bolt 18. T...

Abstract

A high-voltage multifunctional two-position three-way solenoid valve comprises an electromagnet (1), an electromagnet housing (2), a return spring (3), an armature (4), a valve body (5), a valve stem(6), an upper valve seat (7) and a lower valve seat (11). Three vent holes formed in the valve body (5) can be used as fluid inlet holes or fluid outlet holes. The valve stem (6) is mounted in an inner cavity E of the valve body (5) through the upper valve seat (7), an upper valve seat sealing gasket (8), a middle valve sleeve (9), a lower valve port sealing gasket (10), the lower valve seat (11)and a bottom valve sleeve (12). The diameter of the sealing portion of the valve stem (6) and the valve body (5), the diameter of the contact portion of the valve stem (6) and the upper valve seat sealing gasket (8) or the lower valve port sealing gasket (10) and the diameter of the sealing portion of the valve stem (6) and the bottom valve sleeve (12) are identical. One hole A is communicated with a circumferential hole formed in the middle valve sleeve (9). When the valve stem (6) and the upper valve seat sealing gasket (8) or the lower valve port sealing gasket (10) is sealed, the vent holeA is communicated with the other vent holes.

Description

technical field [0001] The invention belongs to the field of high-pressure air supply or oil supply systems for aviation, aerospace, and weapons, and relates to a two-position three-way solenoid valve, in particular to a high-pressure multifunctional two-position three-way solenoid valve. Background technique [0002] In aviation, aerospace, weapons and some special fields, the high-pressure two-position three-way solenoid valve is one of the important basic components of the air supply or oil supply system, which requires smaller volume, lighter weight, higher pressure, greater flow, and tight sealing. Better performance and higher reliability. At present, the existing high-pressure and high-flow two-position three-way solenoid valves often have disadvantages such as complex structure, poor manufacturing process, poor sealing performance, large volume, and heavy weight. [0003] As the control logic of the two-position three-way solenoid valve in the air supply or oil supp...
