The direct -motion solenoid valve is a combination of direct -movement and pilot type. When there is no pressure difference between the entrance and the exit, the electromagnetic force directly lifts up the pilot valve and the main valve in turn, and the valve is opened.When the entrance and exit reaches the starting voltage difference, after the power is powered, the electromagnetic pioneering valve, the pressure of the lower cavity of the main valve rises, and the upper cavity pressure decreases, so as to use the pressure difference to push the main valve upward.Power or medium pressure push the closure part and move down to make the valve close.
Classification of direct movement solenoid valve
1. The nominal size of the small -caliber direct -motion electromagnetic valve small -caliber direct -motion electromaging valve is not greater than Divio. When the small -caliber direct -module electromagnetic valve coil is powered on, the magnetic circuit generates the electromagnetic suction power.So the working medium immediately circulated in the pipeline.When the coil is broken, the electromagnetic force disappears, and the moving iron core falls due to the weight and spring force.2. The two-way two-way solenoid valve and the two-valve seat of both parties. This type of solenoid valve is advanced and its performance is reliable. The work pressure can be from 0 (non-pressure difference)-4.0MPa, especially applicable to 1.33x10-7MPa conditional vacuum system.The valve can achieve the flow of the two direction media (two directions of the two directions), which is currently the worlds most advanced direct -movement solenoid valve.
Direct transmission solenoid valve price
The price of direct solenoid valve with a model of ZW-15 is about 40 yuan.The electromagnetic valve selection should first follow the four principles of security, reliability, applicability, and economy in turn. Secondly, according to the field conditions of the six aspects (that is, pipeline parameters, fluid parameters, pressure parameters, electrical parameters, action methods, ways of action, ways,, movement methods, movements, ways, and movements, action methods, movement methods, movement methods, ways,, movement methods, movements, and action methods, action methods, movement methods, movement methods, and action methods, movements, and action methods, movements, and action methods, movements, and movements, movements, and action methods, movements, and action methods, and movements, action methods, and action methods, and action methods, movements, and action methods.Special requirements for selection).
The principle of direct movement solenoid valve
After the direct -power electromagnetic valve product is powered on, a certain electromagnetic force will be formed on the electromagnetic coil. The closed parts in the valve will be lifted to turn on the solenoid valve. After the power is disconnected, the closing part will return to the original one at this time.Position, the solenoid valve will be closed.In the process of this action, because the upper and lower movements of the closed -piece moving iron core can realize the interruption of the solenoid valve medium, it is also called a direct solenoid valve.
