4WE6J61EG24NK4F6LS SUNNY Solenoid Valve Concrete Pump Truck Accessories
Product Description/Features:
Solenoid valve has a closed chamber, open a hole in different positions, each hole is connected to a different tubing, the middle of the cavity is a piston, two sides are two electromagnets, which side of the magnet coil energized valve body will be attracted to which side, by controlling the movement of the valve body to open or close different oil discharge holes, and the oil inlet hole is usually open, hydraulic oil will enter a different oil discharge pipe, Then through the pressure of the oil to push the piston of the cylinder, the piston in turn drives the piston rod, the piston rod drives the mechanical device. In this way, mechanical motion is controlled by controlling the current of the electromagnet.
Solenoid valves are divided into three categories in principle:
Direct acting solenoid valve
Principle: When energized, the electromagnetic force generated by the electromagnetic coil lifts the closing part from the seat, and the valve opens; When the power is off, the electromagnetic force disappears, the spring presses the closing part on the seat, and the valve is closed.
Features: It can work normally under vacuum, negative pressure and zero pressure, but the diameter is generally not more than 25mm.
Step direct acting solenoid valve
Principle: It is a combination of direct action and pilot principle, when there is no pressure difference between the inlet and the outlet, after the power is turned on, the electromagnetic force directly lifts the pilot small valve and the main valve closing part in turn, and the valve opens. When the inlet and outlet reach the starting pressure difference, after power, the electromagnetic force pilot small valve, the main valve lower chamber pressure rises, the upper chamber pressure drops, so as to use the pressure difference to push the main valve upward; When the power is off, the pilot valve uses spring force or medium pressure to push the closing part and moves downward to close the valve.
Features: It can also be operated at zero pressure difference or vacuum and high pressure, but the power is large, and it must be installed horizontally.
Pilot operated solenoid valve
Principle: When energized, the electromagnetic force opens the pilot hole, the pressure of the upper chamber drops rapidly, forming a low and high pressure difference around the closing part, the fluid pressure pushes the closing part to move upward, and the valve opens; When the power is off, the spring force closes the pilot hole, and the inlet pressure forms a low and high pressure difference around the valve closing part through the bypass hole rapidly, and the fluid pressure pushes the closing part to move down and close the valve.
Features: The upper limit of the fluid pressure range is high, can be installed arbitrarily (need to be customized), but must meet the fluid pressure difference conditions.
the solenoid valve is divided into six branch subclasses from the difference in valve structure and material and the difference in principle: direct acting diaphragm structure, step direct acting diaphragm structure, pilot diaphragm structure, direct acting piston structure, step direct acting piston structure, pilot piston structure.
solenoid valve according to the function classification: water solenoid valve, steam solenoid valve, refrigeration solenoid valve, low temperature solenoid valve, gas solenoid valve, fire solenoid valve, ammonia solenoid valve, gas solenoid valve, liquid solenoid valve, micro solenoid valve, pulse solenoid valve, hydraulic solenoid valve normally open solenoid valve, oil solenoid valve, DC solenoid valve, high pressure solenoid valve, explosion-proof solenoid valve, etc.
