Detailed information on headless electric soft seal gate valve
Advantages of gate valve
1. After the gate valve is opened, the medium channel inside the valve body is straight, without any obstruction, and the flow resistance is very small.
2. When opening and closing, the movement direction of the gate valve is perpendicular to the flow direction of the medium, the pressure is small, and the opening and closing is labor-saving.
3. The height of the gate valve is large, so the opening and closing time is longer, and water hammer is not easy to occur.
4. The two sides of the gate valve channel are symmetrical, and the medium can flow in any direction on both sides, so the installation of the gate valve is very convenient.
5. The length of the structure is short, the manufacturing process is good, and the scope of application is wide.
The gate valve has two sealing surfaces, and the two sealing surfaces of the commonly used mode gate valve form a wedge shape. The wedge angle varies with the valve parameters, usually 50 degrees, and 2 ° 52 'when the medium temperature is not high. The gate of a wedge gate valve can be made as a whole, called a rigid gate; It can also be made into a gate that can produce slight deformation, with its processability, to compensate for the deviation of the sealing surface angle during the processing. This type of gate is called an elastic gate.
Headless electric soft seal gate valves are particularly suitable for domestic drinking water systems, food and pharmaceutical industries, industrial water supply and drainage and sewage treatment, natural gas and gas, etc. Soft seal gate valves can also be widely used in fluid pipelines such as tap water, sewage, construction, petroleum, chemical, food, medicine, textile, power, shipbuilding, metallurgy, energy systems, etc.
