1. Do a good job of cleaning Because the application environment of the knife gate valve is relatively special, it is generally used in industrial pipelines, so it is relatively easy to cause a lot of pollution. Once impurities enter it, the quality of the knife gate valve will also have a big problem. Therefore, it is recommended to do a good job of basic cleaning every once in a while, and check whether there are

Compared with ordinary gate valves, knife gate valves mainly highlight the following advantages: 1.U-shaped gasket has excellent sealing effect. 2.Full-bore design ensures strong medium passing capacity. At the same time, it is easy to install and disassemble under the working condition of dirty medium, and the maintenance is convenient and fast. The seal of the valve can be replaced without removing the gate v

Structural principle of Butterfly Valve 1. Butterfly valve principle The butterfly valve is a structure in which the valve plate rotates along the center line, and the valve plate is small in size. If the handle or worm gear is turned 90 degrees so that the valve is parallel to the medium flow, the valve will open. Therefore, the butterfly valve has the characteristics of simple structure, small size, light wei

The ball valve is evolved from the plug valve. Its opening and closing part is a sphere, which is opened and closed by rotating the sphere 90 degrees around the stem axis. The difference is that it is a sphere with a circular through hole or passage through its axis. The ratio of the sphere to the channel opening should be such that when the sphere is rotated 90 degrees, there should be a full sphere at the inlet and

Knife gate valve is also called knife gate valve, knife gate valve, slurry valve and mud valve. Its opening and closing parts are gate plates. The movement direction of the gate plate is perpendicular to the direction of the fluid. The medium is cut off by a knife edge gate which can cut fiber materials. The gate plate has two sealing surfaces. The two sealing surfaces of the most commonly used mode gate valve form w

The electric control valve is a hydraulically operated valve with a solenoid valve as a guide valve. It is often used for automatic control in water supply and drainage and industrial systems. The control response is accurate and fast, and the pipeline system is remotely opened and closed according to electrical signals to realize remote operation. Can replace gate valve and butterfly valve for large electric operati
