Sliding vane type three-way electromagnetic valve

Abstract

The invention discloses a sliding vane type three-way electromagnetic valve. The sliding vane type three-way electromagnetic valve comprises a valve body, a sealing base, a valve element assembly andan electromagnetic driving assembly, wherein the valve body is provided with a valve cavity, an inlet, a first outlet and a second outlet; the sealing base is provided with a first valve port communicating with the first outlet and a second valve port communicating with the second outlet, the valve element assembly comprises a valve element, the valve element comprises a first slide piece and an elastic sealing element, and the face, facing the first sliding piece, of the elastic sealing element is provided with a first protruding part and a second protruding part; the first sliding piece is provided with a first protruding part penetrating hole and a second protruding part penetrating hole, and each protruding part penetrates through the corresponding protruding part penetrating hole correspondingly, and abuts against the sealing base; when the valve element assembly is in a first position, the second protruding part is used for blocking a second valve port, and the inlet communicateswith the first outlet through the first valve port; when the valve element assembly is in a second position, the first protruding part is used for blocking the first valve port, the inlet communicates with the second outlet through the second valve port. According to the valve, the closed outlet can be ensured to obtain a reliable fluid seal.

Description

technical field [0001] The invention relates to a solenoid valve, in particular to a sliding vane three-way solenoid valve. Background technique [0002] figure 1 and figure 2 A schematic cross-sectional structure diagram of an existing sliding vane three-way solenoid valve is shown. Such as figure 1 and figure 2 As shown, the sliding vane three-way solenoid valve includes a valve body 1a, a sealing seat 2a, a valve core assembly and an electromagnetic drive assembly. [0003] The valve body 1a has a valve chamber 10a, an inlet 13a, a first outlet 11a and a second outlet 12a. The inlet 13a, the first outlet 11a and the second outlet 12a communicate with the valve chamber 10a respectively. The sealing seat 2a is fixedly arranged in the valve cavity 10a, and blocks the first outlet 11a and the second outlet 12a. The sealing seat 2a defines a first valve port 21a communicating with the first outlet 11a and a second valve port 22a communicating with the second outlet 12...

AI Technical Summary

Problems solved by technology

[0008] The sliding piece 34a and the sealing seat 2a are usually made of stainless steel, and it is difficult to achieve a tight fit between the two, so it is easy to cause fluid leakage, resulting in fluid passing through the outlet that should be closed, thereby affecting the three-way solenoid valve. work
