A valve is a device used to control the flow and direction of air or liquid. There are two types of valves, one is installed underground and the other is installed on the ground. Valves can also be divided into manual valves and electric valves according to their types. The manual valve technology we usually use for ordinary valves has a relatively small action torque, while the action torque of electric valves is relatively large. Do you know the working principle of electric valves?
1.Introduction to Electric Valves
Electric valve is a type of valve controlled by an electric actuator, which is mainly used to open and close the valve. Electric valves can be divided into two parts. One part is the upper part, usually composed of an electric actuator, and the lower part is the valve, just like ordinary valves, but using an electric device. The advantage of this valve is that it can better control the liquid medium and is not affected by climate or air pressure. However, the cost of electric valves is relatively high, and they cannot work in humid environments for a long time, which will affect the electric actuator.
2.Operating principle
Electric valves have two components, electric actuators and valves. Electric valves mainly use electric actuators as the main source of power. This device can be used to open and close valves, effectively achieving fast valve opening and closing, and smoothly completing the purpose of medium opening and closing in pipelines. Electromagnetic valves use the magnetic field of an electromagnetic coil to pull the valve core, so they can change the on/off of the valve body and the power-off of the coil.
3.purpose
Electric valves are generally used in pipelines of gas, liquid, and air systems as medium flow regulators, which can play an AO control role.
4.Operation method
Before operating the electric valve, carefully read the operation manual and do not use it casually. Before operation, it is necessary to clarify the gas flow direction for installing the electric valve, check the appearance of the electric valve, and see if it is damp or damaged,
moisture should be dried, and any problems should be repaired. Before starting an electric valve that has been inactive for 3 months, it is best to check the clutch to see if it can still operate and be used normally.
