进口零压差启动电磁阀美国阿卡迪亚品牌


进口零压差启动电磁阀Product Description:

 

The utility model comprises a valve seat, a valve cover, a sleeve fixed with the valve seat and the valve cover through threaded connection, and a first seal is arranged between the sleeve and the valve seat for sealing; The upper part of the casing is provided with a static core iron, and the casing is welded with the static core iron; A moving core iron component and a pilot component are arranged below the static core iron, the pilot component is arranged in the internal cavity of the moving core iron component, and a return spring is arranged between the pilot component and the static core iron; The moving core iron part is provided with a second seal. When the valve is closed, the lower part of the second seal fits and seals with the valve port on the valve seat. The return spring is butted with the pilot component, which can reduce the load impact on the seal during the closing process of the valve body, prevent liquid hammer and prolong the service life of the valve body

 

进口零压差启动电磁阀characteristic:

 

The field of control valve often involves solenoid valve to control the on-off of medium in the system. According to different functional requirements in the system, it can be divided into normally open type and normally closed type. According to the internal structure of solenoid valve, it can be divided into direct acting type and pilot type. Pilot solenoid valve often needs to drive a small orifice (pilot valve) inside the solenoid valve through solenoid coil. When the pilot valve is opened, It will make the sealing moving parts sealed on the larger orifice open the larger valve port (main valve) under the action of pressure difference, so as to realize the medium on-off function in the control system. Then, for general pilot solenoid valves, the opening is often insufficient or the valve cannot be opened when the pressure difference between the inlet and outlet of the valve body is zero or the pressure difference is very small (below 1psi), while for direct acting solenoid valves, although zero pressure difference can be started, However, the larger the valve port, the greater the electromagnetic force of the supporting coil, so the coil is often large and the cost is high.

 

Principle:

 

Make the core iron quickly reach a certain initial speed of auxiliary valve opening without pressure difference force and spring force, and then continue to drive the pilot parts by the core iron to open the pilot hole, so as to reduce the pressure difference between the upper and lower parts of the seal sealed on the valve port and reduce the load of further opening the valve port; The seal is directly driven by the snap ring to open the valve port later, so as to realize zero differential pressure valve opening. The return spring is butted with the pilot component, which can reduce the load impact on the seal during the closing process of the valve body, prevent liquid hammer, prolong the service life of the valve body, greatly reduce the requirements for the electromagnetic force of the supporting coil and the manufacturing cost, inherit the characteristics of zero differential pressure opening of the direct acting solenoid valve, and the use is more stable and reliable.
