Classification of Electric Valves
The electric valve, as its name implies, is to drive the opening and closing of the valve by power supply. The valve is mainly composed of two parts: the upper part is the electric actuator, and the lower part is the valve. In the industrial process, it is used to control the travel and flow of various fluids, such as water, oil, chemical liquid. The electric valve is a kind of automatic control valve which is widely used in recent years. With its reliability and various control functions, it meets the working conditions that most common valves can not meet, and becomes an indispensable control equipment in process pipelines.
The electric valve has simple structure and long service life. And it is suitable for almost all media, and can greatly reduce the labor intensity of operators. What's more, it is suitable for the condition that the equipment cannot be operated manually or is difficult to approach. Also, this valve can be operated remotely.
Classification of electric valves:
1. Electric valves are generally divided into two categories according to different actuators, one is the rotary motion valve and the other is the linear motion valve. The former controls 90-degree rotation to make the valve on and off, and the latter is to realize the up and down movement of the valve plate so that it is usually used for equipment with a high degree of automation.
2. According to the function, the electric valve is divided into switch type, adjustment type, intelligent type and explosion-proof type. Among them, the switch-type valve can only be fully opened and closed, and the adjustment type can control any opening to achieve the function of regulating the flow.
3. According to the valve location, this valve can be divided into common electric ball valves, electric butterfly valves, electric regulating valves, electromagnetic valves, electric gate valves, electric stop valves, etc.
4. According to the shape of the valve body, the valve can be divided into ordinary electric valves and micro electric valves.
