ZCZG/ZCZH high-temperature and high-pressure solenoid valve is a pilot direct-acting solenoid valve. It can be used in water, light oil, heavy oil, non-corrosive gas and steam respectively. For example, in the drainage system of pumping pipe and the exhaust system of evaporator in power station, the medium in the pipeline can be adjusted automatically and controlled automatically by two positions. Remote control.
Structural characteristics
High temperature resistance: metal hard seal is used to improve the service temperature. Medium fluid temperature can reach 425 degrees centigrade.
Wear resistance: material selection is reasonable. Valve cup and guide sleeve make use of the lubrication of the fluid skillfully to reduce wear.
Using the lever principle to ensure the complete isolation of the coil and valve body.
Structure principle
When the solenoid valve is electrified, the connecting rod is raised, the rotating shaft is driven to rotate, and the secondary valve is opened. Since the vice valve is opened,
The pressure fluid in the upper part of the main valve cup is discharged, so the pressure in the lower part of the main valve cup is higher than that in the upper part, so the pressure in the lower part pushes the main valve cup upward. After the main valve is opened, the upper and lower pressures are equal. The valve cup is placed in a balanced state under the action of electromagnetic force and upper and lower pressures, and the valve is opened. When the power is cut off, the auxiliary valve is closed under the action of the armature weight and return spring. After the auxiliary valve is closed, the pressure on the upper part of the main valve cup rises and the main valve cup is pressed down to achieve the sealing effect of flow cut off and the valve is closed.
