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

1. Floating ball valve The main structural features of the floating ball valve are: (1) The valve is equipped with open and closed position indications; (2) Locking device; (3) Anti-flying structure of valve stem; (4) Anti-static device; (5) Fireproof structure; (6) Unique valve seat sealing structure; (7) The middle flange (the connecting part of the valve body and the left body) has no leakage structure.

The ball valve is evolved from the plug valve. Its opening and closing part is a sphere, which uses the sphere to rotate 90° around the axis of the valve stem to achieve the purpose of opening and closing. The ball valve is mainly used to cut off, distribute and change the direction of the medium flow in the pipeline. The ball valve designed as a V-shaped opening also has a good flow adjustment function. advanta
