Solenoid valve provides service guarantee for high-speed rail trains
Dec 30, 2021
Solenoid valves are industrial equipment operated by magnetic induction, used in power monitoring systems to adjust the orientation, total flow, speed and other main parameters of substances. The stainless steel solenoid valve is operated by the utility of magnetic induction, and the key adjustment method is operated by the automobile relay. In that way, the solenoid valve can cooperate with different power circuits to complete the desired operation, and the precision of the operation and the flexibility of operation can be ensured. The 4 types of gate valves for high-speed trains developed by China Aerospace Science and Industry Co., Ltd. passed the approval of Beijing Saide High-tech Railway Electric Technology Co., Ltd. with a high score of 97.3. So far, the technical strength of products such as solenoid valves and pressure regulating valves developed for the supporting facilities of rail trains has long reached the level of similar products abroad. Factory 695 is a solenoid valve manufactured by rail train technology. It is the first two-position two-way solenoid valve with a snap-fit structure and has many technological innovations.
Technically, the traditional craftsmanship of pressing polyphenylene sulfide on metal seat cushions for imported products has been changed, and plastic materials have been changed to develop airtightness, which completely eliminates the leakage of imported products in terms of airtightness; in the main suspension plate The structure of the auxiliary valve has been improved to reduce the reaction time and increase the reaction rate of the solenoid valve.
In addition, the team has independently improved the magnetic density at work on the new solenoid valve based on the past work experience in the maintenance of common failures of solenoid valves manufactured by Alstom in France installed on Chinese rail trains. That way, for the regulation of response time, solenoid valve coils will no longer have to be repaired at the place of origin, and only need to adjust the magnetic density during work on the electric locomotive, which not only saves time, but also greatly reduces maintenance costs. Products such as solenoid valves and pressure regulating valves for rail train manufacturing technology have the development potential of their own imported products. At the same time, the research and development, production and processing and material testing capabilities of gate valves for rail train supporting facilities have already passed experimental testing.
