Abstract

The invention provides an electromagnetic valve comprising a valve body. The valve body is provided with a valve opening, an inlet and an outlet, wherein the inlet and the outlet communicate through the valve opening. A main valve element provided with a damping opening is slidably arranged at the valve opening. A guide tube is fixedly arranged on the valve body. An attractor is fixedly arranged on the upper portion of the guide tube. Core iron and a core iron cap fixedly connected with the core iron are slidably arranged inside the guide tube. An elastic mechanism is arranged between the attractor and the core iron. A one-way valve element is slidably arranged in the interior, corresponding to the damping opening, of the core iron cap. A pressure releasing channel is formed in the side wall of the core iron cap. The one-way valve element is provided with a first position located between the pressure releasing channel and the valve opening and a second position located on the side, far from the valve opening, of the pressure releasing channel. According to the electromagnetic valve, the problem that in the prior art, shaking occurs due to reverse air inlet of an electromagnetic valve, and noise is caused consequently can be solved.

Description

technical field [0001] The invention relates to the technical field of hydraulic valves, in particular to a solenoid valve applied to refrigeration systems such as air-conditioning, freezing and refrigeration. Background technique [0002] As an automatic control element, the solenoid valve mainly realizes the clutch of the valve body relative to the valve seat through the magnetic force generated by the electromagnetic coil, so as to achieve the purpose of opening / closing the valve body. [0003] The inlet pipe and outlet pipe of the existing solenoid valve are specific. When the air is reversed, the valve core is subjected to the upward momentum of the gas and the downward force of the spring. When the elastic force and the reverse air force are close to the same, it is easy to produce Resonance will produce jitter and cause noise. Contents of the invention [0004] The purpose of the present invention is to provide a solenoid valve to solve the problem in the prior art...
