ZCG high-temperature solenoid valve

Product Introduction: High temperature solenoid valve is a type of pilot direct acting solenoid valve, which is widely used in shipbuilding heavy industry, testing equipment, heating equipment, hydraulic equipment, etc. Its working temperature is above 300 ℃ in thermal conduction systems. In the drainage system of power station exhaust pipelines and the exhaust system of evaporators, the main function is to perform dual position automatic regulation and remote control of the medium in the pipelines. The valve cores are all stainless piston type, and the piston rings are made of special temperature resistant and wear-resistant materials; There is no direct friction between the piston and the metal valve chamber, and there is no restriction on the installation direction of the valve body; Specially designed coils with a heat dissipation structure, making them less prone to burning out; After a long pause, the action is restarted with the same sensitivity and a starting pressure of 0.2MPa.

Product Features:

1. High temperature resistance:

The sealing material is made of high temperature resistant material, the coil part is made of high temperature resistant electrical material, and a heat dissipation mechanism is added to the periphery.

2. Corrosion resistance:

The main components such as valve plug and valve body are made of stainless steel and copper alloy, with good anti-corrosion performance.

3. Wear resistance: Reasonable material selection, clever use of fluid lubrication between valve plugs and valves to reduce wear.

working principle

When the electromagnetic iron of the solenoid valve is energized, the connecting rod is lifted, which drives the shaft to rotate and opens the auxiliary valve. Due to the opening of the auxiliary valve, 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, which pushes the main valve cup upwards. After the main valve is opened, the upper and lower pressures are equal, and the valve cup is placed in a balanced state under the action of electromagnetic force and upper and lower pressure, and the valve is opened. When the power is cut off, under the self weight of the armature and the action of the return spring, the auxiliary valve is closed. After the auxiliary valve is closed, the pressure on the upper part of the main valve cup rises and presses the main valve cup down, achieving the function of cutoff sealing, and the valve is closed.
