Tanggu valve is a valve, and an electric head is an electric head. There are professional manufacturers. Generally, valve manufacturers do not produce electric heads. General valves can be equipped with electric heads. Therefore, professional electric valve manufacturers are relatively powerful!

The electric valve simply uses an electric actuator to control the valve, and then complete the opening and closing of the valve. It can be divided into upper and lower parts, the upper part is the electric actuator, and the lower part is the valve.

Advantages: good effect on liquid medium and large diameter gas, not affected by climate. Not affected by air pressure.

Disadvantages: high cost, not good in humid environment.

Daily maintenance of electric valve

1. The electric valve should be stored in a dry and ventilated room, and both ends of the passage must be blocked.

2. Electric valves stored for a long time should be checked regularly, the dirt should be removed, and anti-rust oil should be applied to the processing surface.

3. After installation, it should be checked regularly. The first check items are:

(1) The wear condition of the sealing surface.

(2) The wear condition of the trapezoidal thread of the stem and stem nut.

(3) Whether the packing is outdated and ineffective, if it is damaged, it should be replaced in time.

(4) After the electric valve is repaired and installed, the sealing function test should be carried out.

For electric valves in operation, all valve parts should be complete and intact. Flange threads and bolts on brackets should not be short, the threads should be intact, and no loosening is allowed. If the tightening nut on the handwheel is found to be loose, it should be tightened in time to avoid abrasion of the connection or loss of the handwheel and nameplate. If the handwheel is lost, it is not allowed to replace it with a live wrench, and it should be completed in time. Packing glands are not allowed to tilt or have no preload clearance. For electric valves in environments that are easily infected by rain, snow, dust, sand and other pollutants, the valve stem should be equipped with a protective cover. The scale on the electric valve should be kept intact, accurate and clear. The lead seals, caps, pneumatic accessories, etc. of the electric valve should be completely intact. The insulation jacket should be free of depressions and cracks.

It is not allowed to knock, stand or support heavy objects on the electric valve in operation; especially non-metal electric valve and cast iron electric valve, it should be stopped.

The electric valve is usually connected by an electric actuator and a valve, and becomes an electric valve after the device is debugged. The electric valve uses electric energy as power to connect the electric actuator to drive the valve to complete the opening and closing of the valve and the adjustment action. Then achieve the intention of switching or conditioning the pipeline medium.

Solenoid valve is a type of electric valve; it uses the magnetic field generated by the electromagnetic coil to pull the valve core, and then changes the on-off of the valve body.
