Solenoid valve diagram How to see it, a simple explanation of the solenoid valve schematic diagram
2. Look at how many connected or disconnected points there are in a single grid. Several points represent several ports (holes), including air intake, work, and exhaust holes. There are 5 in the picture. Therefore, the valve shown is a five-port, two-position valve.
3. The grid representing letters or numbers represents the initial position of the valve, that is, the initial working state. As shown in the figure, the grid on the left represents the initial working state of the valve, which is the state when no power is supplied.
4. Look at the grid at the initial position. The letters marked in the picture from left to right and from top to bottom are ABRPS (the second grid corresponds to the hole position of the first grid). AB is the working port, RS exhaust port, and P air inlet, which are industry standards. The direction of the arrow indicates connection, and the T-shaped point indicates difference. As shown in the figure, PA is connected, P hole inlets air, A hole exhausts air (working);SB is connected, B hole exhausts to S hole, and R exhaust port is blocked.
5. Look at the second grid, AR is open, hole A ventilates to hole R;PB is open, hole P is air in, hole B is air out, and hole S is blocked.
6. Look at the symbols next to the grid with text. This represents the initial control mode of the valve. The swaying top represents the spring, and the triangle below represents the air control. Therefore, the initial state of the valve body, or the reset state, is determined by Spring and air are controlled together, so-called spring and air reset.
7. Look at the symbol next to the other grid. In the same way, it represents the control mode of the valve when it is working. As shown in the figure, it can be divided into two rectangles. The left rectangle has a triangle, which represents air control. The right rectangle has a diagonal line in the middle. This represents the coil, that is, it is an electromagnetic air control valve.
In general, this valve is, Solenoid valve is controlled by air. After the power is turned on, it functions as shown in Article 5. When the power is turned off, the spring Under the action of Qi, the initial state is shown in line 4.
