Main uses of dual flow solenoid valve, working principle of dual flow solenoid valve

Dual flow electromagnetic Main purpose of valve

Applicable media are steam, air, oil, water, gas and other fluids, dual flowSolenoid valveThe valve body is made of stainless steel, and all internal parts are also made of stainless steel. Adopting a double valve body and double flow channel design, the large valve enables fast refueling, and the small valve achieves precise refueling, thereby achieving refueling control of the dispenser. This valve has long been used in the automatic control of oil dispensers, precision filling and other systems.

Adopts a double valve body and double flow channel design, and the large and small flow channels are controlled by independent coils. When refueling, first open the small valve, then open the large valve to achieve rapid refueling, then close the large valve, and use the small valve to achieve precise refueling. When the oil is full, close the small valve again, and the gasoline will be cut off and no more oil will be discharged.

Working principle of dual-flow solenoid valve

When filling, open the large valve first. When the filling is almost completed, close the large valve and open the small valve so that the small valve Achieve the purpose of precise filling.

Explanation of advantages of dual-flow solenoid valve

1. Double flow solenoid valve, mainly including electromagnetic control device , main valve, auxiliary valve, pilot valve and main valve switching element. Its main feature is that the main valve switching element is composed of a piston mechanism, which solves the problem that the existing rubber diaphragm is easy to harden and break when used in a medium and low temperature environment in gasoline medium. It has the advantages of wide temperature range, reliable operation, long service life, etc. It is very suitable for solenoid control valves of oil dispensers in various temperature environments.

2. There are There are two channels, one is the main flow channel and the other is the auxiliary flow channel. The auxiliary flow channel is used for precise quantitative compensation. This dual-flow solenoid valve can easily control the size of the liquid in the pipeline, thereby meeting the requirements for accurate liquid measurement.

3. The waterproof hammer switch is graded to avoid water Hammer spawns.

Double flow solenoid valve installation precautions:

1. The pipeline should be flushed before use. If the medium is not clean, a filter should be installed to prevent impurities from hindering the normal operation of the solenoid valve. .

2. Solenoid The valve works in one direction and cannot be installed backwards. The arrow on the valve indicates the direction of movement of the fluid in the pipeline and must be consistent.

3. The solenoid valve should be installed horizontally with the valve body and coil Vertically upward to increase service life.

4. The steam solenoid valve needs to be connected after installation The medium test operation is performed several times, and it can be put into formal use only after it is confirmed to be normal.

5. Pressure needs to be installed on the pipes before and after the solenoid valve gauge to observe pipeline pressure.
