Solenoid valve is a type of electric valve; it uses the magnetic field generated by the electromagnetic coil to pull the valve core, thereby changing the on-off of the valve body, the coil is de-energized, and the valve core is retracted by the pressure of the spring. The electric valve simply uses the electric actuator to control the valve, so as to realize the opening and closing of the valve. It can be divided in

The solenoid valve is a solenoid valve that generates a magnetic force to attract and overcome the pressure of the spring to drive the valve core to move after the solenoid coil is energized. It is only a solenoid coil, which has a simple structure and a low price, and can only be switched. The valve is divided into (shut-off valve) and regulating valve. The shut-off valve is a two-position type of work, that is, fu

When the gate valve is closed, the sealing surface can only rely on the medium pressure to seal, that is, only relying on the medium pressure to press the sealing surface of the gate to the valve seat on the other side to ensure the sealing of the sealing surface, which is self-sealing. Most gate valves are forcibly sealed, that is, when the valve is closed, the gate must be forced against the valve seat by external

The globe valve and the gate valve have some similarities in appearance, and both have the function of cutting off in the pipeline, so many friends who have little contact with the valve will confuse the two. different structure When the installation space is limited, attention should be paid to the selection. The gate valve can be tightly closed with the sealing surface by the medium pressure, so as to achieve the

Gate valve We all know that the gate valve is a very widely used valve, so how does the gate valve work? Let's find out together. The opening and closing part of the gate valve is the gate, and the movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate has two sealing surfaces. The two

While valves are probably a small part of your piping manner or gadget in phrases of area, they’re regularly a significant part of the layout and construct budget. They have a widespread effect on long-time period prices and standard gadget performance. The first issue to remember is the general length of the valve -- each in phrases of bodily dimensions and phrases of inner length and glide rates (CV). C
