What Is a Vent Valve Solenoid?
Solenoid valve is an industrial device controlled by electromagnetics. It is an automatic basic component used to control fluids. It belongs to actuators. Pneumatic solenoid valve is one of them. It controls or moves the valve body to block or leak different oil. Hole, and the oil inlet hole is always open, the hydraulic oil will enter different drain pipes, and then the piston of the cylinder is pushed by the oil pressure of the pneumatic solenoid valve. In this way, the current of the solenoid of the pneumatic solenoid valve is controlled. Mechanical movement of the entire solenoid valve. [1]
Pneumatic solenoid valve
- Solenoid valve is an industrial device controlled by electromagnetics. It is an automatic basic component used to control fluids. It belongs to actuators and pneumatic
- Solenoid valve is an automatic basic element used to control fluids and belongs to actuators; it is not limited to hydraulic and pneumatic. Solenoid valve is used to control the direction of hydraulic flow. The mechanical devices of the factory are generally controlled by hydraulic cylinders, so solenoid valves are used.
- It can work normally under vacuum, negative pressure and zero pressure, but the diameter generally does not exceed 25 mm.
- It can be operated under zero pressure difference, vacuum or high pressure, but the power is large, and it must be installed horizontally.
- The pneumatic solenoid valve has a closed cavity, and there are through holes in different positions. Each hole of the pneumatic solenoid valve leads to a different air pipe. The middle of the cavity is a valve. Two sides are two electromagnets. Which side of the magnet coil is energized. Which side the valve body will be attracted to;
- The pneumatic solenoid valve blocks or leaks different exhaust holes by controlling the movement of the valve body, and the air intake holes are always open, high pressure gas will enter different exhaust pipes, and then pushed by the air pressure of the pneumatic solenoid valve The piston of the cylinder controls the mechanical movement of the entire solenoid valve by controlling the current of the solenoid of the pneumatic solenoid valve.
- Operating principle of pneumatic solenoid valve
- When we talk about the working position of the pneumatic solenoid valve (solenoid valve on or off), it actually refers to the position of the spool of the pneumatic solenoid valve.
- The spool is in the A position when the coil is not energized and in the B position when the coil is energized. When the valve core of the pneumatic solenoid valve is in different positions, it plays a role of either opening or closing to each interface on the valve body. For example, a two-position solenoid valve means that the spool of the solenoid valve has two different working positions (on or off). For a pneumatic solenoid valve, it is the state of the solenoid valve that is powered on and off. It is the opening and closing of the valve. Two-way and three-way solenoid valves refer to two or three passage openings on the valve body of the pneumatic solenoid valve. The two-position two-way solenoid valve has two channels of one input and one output, which is the most common pneumatic solenoid valve; the two-position three-way solenoid valve is three channels of one input and two output, and the two output channels are corresponding. The connections are normally open and normally closed. Similarly, three-way, four-way and five-way all refer to the number of fluid channels on the valve body. [1]
