Embodiment Construction

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] Such as figure 1 , 2 As shown, the solenoid valve for air system conversion includes a valve body 1 and an electromagnet 2 arranged on one side of the valve body 1. The valve body 1 is provided with an air inlet port 3 and a vent 4. The valve body 1 A first chamber 5, a second chamber 6, a third chamber 7 and a fourth chamber 8 are opened inside;

[0019] The first chamber 5 is provided with an iron core piston disc 9 driven by the electromagnet 2, and the front wall 5.1 close to the iron core piston disc 9 in the first chamber 5 is provided with a front hole communicated with the air inlet port 3 5.2, the rear wall 5.3 opposite to the front wall 5.1 is provided with a rear hole 5.4 communicating with the outside world, the front hole 5.2 and the rear hole 5.4 are respectively facing the two sides of the iron core piston disc...

Abstract

The invention discloses a solenoid valve for air system conversion. The solenoid valve is different from an existing solenoid valve. Three channels are arranged and connected with an air inflowing connector so that each channel can be thin, the temperature of air is greatly lowered after the air enters the solenoid valve and the heat of the air is dissipated, the influence on the internal components is small, the solenoid valve can not be damaged easily, and the service life of the solenoid valve is prolonged. The solenoid valve with double margins is adopted preferentially, and the stability is high.

Description

technical field [0001] The invention relates to a solenoid valve, in particular to a solenoid valve for switching an air system. Background technique [0002] The lubricating oil system of the engine is a very important system of the engine. It mainly lubricates the important parts of the engine, especially the rotating parts. The sealing of the lubricating oil system is a key issue. Once the seal fails, the lubricating oil will leak light and make the engine The entire oil system fails, causing engine failure and possibly engine shutdown. [0003] In the prior art, mechanical valves with springs are commonly used to seal the lubricating oil system. The existing mechanical air valves have poor thermal effect, short service life, poor sealing and stability. If electromagnetic valves are used as valve components It will be able to reliably seal the lubricating oil system, but the gas channel in the existing pneumatic solenoid valve has a large aperture. When working under hig...
