1. What is a two-position three-way solenoid valve?
1, 3-way solenoid valve is very common in practical application, usually used in conjunction with single-acting pneumatic actuator, which can be used to connect or cut off the gas source in production, thus switching the gas path of the gas control membrane head. Now let's see what a two-position three-way solenoid valve is.
2. The working position of the solenoid valve (whether the solenoid valve is on or off) actually refers to the position of the valve core of the solenoid valve. When the coil is not energized, the valve core is in position A, and when the coil is energized, the valve core is in position B.. When the valve core of the solenoid valve is in different positions, it plays the role of connecting or closing the interfaces on the valve body. For example, the two-position solenoid valve means that the valve core of the solenoid valve has two different working positions (on or off), which are charged and powered off for the solenoid valve; For the valve it controls, it is the opening and closing of the valve.
3. The two-way three-way solenoid valve means that there are two or three channels on the valve body of the solenoid valve. The two-position two-way solenoid valve has two channels, one in and one out, which is the most common solenoid valve. The two-position three-way solenoid valve is three channels with one inlet and two outlets, and the two outlet channels are normally open and normally closed respectively. Similarly, three-way, four-way and five-way also refer to the number of fluid channels on the wide body. The picture shows the gas path switching caused by the on/off state switching of the coil of the two-position three-way solenoid valve.
4. From the gas path, the two-position three-way solenoid valve has three ventilation channels. Generally, one channel is connected with a gas source, as shown in the figure, No.2 port; One of the other two channels is connected to the air inlet of the actuator, such as port 1, and the other is connected to the air outlet of the actuator. A muffler is usually added to eliminate noise, such as port 3.
