Recently, many users have asked a question, we used solenoid valves before, and now want to change to the electric valve you said, but I want to know what is the difference between solenoid valves and electric valves? Today, Xiaobian will simply give you a reason for the difference between solenoid valve and electric valve.
The difference between electric valve and solenoid valve is as follows:
I. Introduction
1, solenoid valve: electromagnetic coil after the power generated magnetic attraction to overcome the pressure of the spring to drive the spool action, a solenoid coil, simple structure, cheap price, can only achieve switching;
2, electric valve: Ball valve is an integral body will not be affected by pipeline stress and bolts. The gear design of copper and stainless steel in the actuator can ensure the accuracy of the adjustment control and the output torque is large. Low running current, can use battery power supply, quick and convenient switching, as long as the stem rotates 90°, the ball valve will be fully opened or fully closed, to achieve fast opening and closing.
Ii. Use
1. Solenoid valve: driven by coil, it can only be opened or closed, and the action is short when switching; It is used for switching control of liquid and gas pipelines, and is generally used for controlling small pipelines.
2, electric valve: generally driven by a motor, the switch needs a certain time to complete, can also be adjusted; For the adjustment of liquid, gas and other media flow in the pipeline, electric valves are also used in the control of large valves and wind systems to do switch control, and there can be valve in place signal feedback.
Three, the role
1, the solenoid valve can be reset after the general power failure, the flow coefficient is very small, the working pressure difference is very small, and it is easier to be damaged by the voltage impact, which is equivalent to the switching effect, opening and closing two roles.
2, the electric valve power to reset the need to add a reset device (such as the actuator with a farrah capacitor), driven by the motor, more resistant to voltage impact, the solenoid valve is fast opening and fast closing, generally used in small flow and small pressure, requiring a large switching frequency of the electric valve vice versa. The opening of the valve can be controlled, and the state is open, closed, half-open and half-closed, which can control the flow of the intermediate quality of the pipeline and the solenoid valve can not meet this requirement.
The above is basically the difference between electric valve and solenoid valve, have you learned?
