Power valve is a device that controls the opening and closing of valves by electromagnetic force, and its working principle is to control the opening and closing of valves by utilizing the magnetic field generated by electromagnets. The electric power valve consists of an electromagnet, a valve and a control system. When the electromagnet is energized, the electromagnetic field generated attracts the valve and opens it; conversely, when the electromagnet is de-energized, the electromagnetic field disappears and the valve closes.
The working principle of the power valve can be simply summarized as follows: by controlling the electromagnet to energize and de-energize, to control the opening and closing of the valve. The control system can adjust the electromagnet's energizing time and de-energizing time according to the need, so as to control the opening and closing speed and opening degree of the valve. In this way, precise control and regulation of the fluid can be realized.
Power valves are widely used in industrial control systems, such as water treatment, heating systems, air conditioning systems, petrochemicals, automotive industry and other fields. It has the advantages of simple structure, fast response speed, high reliability, high degree of automation, etc. It can improve the control accuracy and efficiency of the system, and reduce energy consumption and labor costs. Therefore, power valves play an important role in modern industrial production.
