Problems solved by technology

[0002] In the automobile air-conditioning system, the function of switching between circulation and throttling is realized by using the parallel connection of the solenoid valve and the short throttle tube; in this scheme, the flow direction of the fluid is controlled by controlling the opening and closing state of the solenoid valve Or the open and close state of the flow path involved; the pressure drop in the system is controlled through the throttle tube; this will inevitably lead to disadvantages such as many parts, complex structure, heavy weight, and high cost, which violates the current trend of automobile lightweight and cost reduction. requirements

Abstract

The invention discloses an electromagnetic valve with a throttling function. The electromagnetic valve comprises a valve body, a valve element assembly assembled in the valve body, a valve seat assembly is installed on the upper part of the valve element assembly, and an electromagnetic coil assembly is installed on the upper part of the valve seat assembly; an inlet hole is formed in one side ofthe valve body, an outlet hole is formed in the other side of the valve body, a valve body main cavity is formed between the inlet hole and the outlet hole, and the valve body main cavity is connectedwith the outlet hole through a channel; the joint of the valve body main cavity and the channel is a main valve opening; a damping hole is formed in the valve body main cavity, and the damping hole communicates with the valve body main cavity and the channel; and the valve element assembly comprises a valve element, the valve body main cavity and the lower half segment of the valve element are assembled to form an accommodating cavity, when the bottom of the valve element abuts against the main valve opening and the main valve opening is closed, the damping hole communicates with the accommodating cavity and the channel. The throttling electromagnetic valve has the characteristics of throttling depressurization.

Description

technical field [0001] The invention relates to the field of solenoid valves, in particular to a solenoid valve with throttling function. Background technique [0002] In the automobile air-conditioning system, the function of switching between circulation and throttling is realized by using the parallel connection of the solenoid valve and the short throttle tube; in this scheme, the flow direction of the fluid is controlled by controlling the opening and closing state of the solenoid valve Or the open and close state of the flow path involved; the pressure drop in the system is controlled through the throttle tube; this will inevitably lead to disadvantages such as many parts, complex structure, heavy weight, and high cost, which violates the current trend of automobile lightweight and cost reduction. requirements. [0003] In view of the above problems, the present invention designs a solenoid valve with throttling function, and this case arises from it. Contents of th...
