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

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

The closing time of the electric head of the electric gate valve does not exceed 30S. What is the effect of the open closing time? The opening and closing time of the electric gate valve? Turning to the left is to close, and to the right is to open the valve. Pay attention to the arrow mark on the valve. The switching time of the electric head of the electric gate valve is determined by the speed, pitch, and forming

The strength test of the gate valve is the same as that of the stop valve. There are two methods for the sealing test of the gate valve. ① Open the gate to increase the pressure in the valve to the specified value; then close the gate and immediately take out the gate valve to check for leakage at the seals on both sides of the gate or directly inject the test medium into the plug on the valve cover to the specified
