Introduction to the characteristics of forged flange high-pressure ball valve and its scope of application
The main feature of the high-pressure ball valve is its compact structure, reliable sealing, simple structure, convenient maintenance, sealing surface and spherical surface are often in a closed state, not easy to be eroded by the medium, easy to operate and maintain, suitable for water, solvents, acid and natural gas and other general working media, but also suitable for working conditions of harsh media, such as oxygen, hydrogen peroxide, methane and ethylene, etc., in various industries have been widely used. The ball valve body can be monolithic or combined.
Forged flange high pressure ball valve features:
1. Among the various valves, the flow resistance of the ball valve is the smallest, when the full-diameter ball valve is opened, the ball channel, the valve body channel and the connecting pipe are equal in diameter and form a diameter, and the medium can flow through almost without loss
2. The ball valve can be fully closed and fully opened by rotating 90°, and the opening and closing are fast. Compared with gate valves and globe valves of the same specifications, ball valves are small in size and light in weight, which is convenient for pipeline installation
3. The switch indication of the forged flange high-pressure ball valve: the ball, stem and handle are the moving parts of the valve and are an assembly unit. The stem head adopts a square structure, which can easily identify the open or closed position of the valve from the position of the handle. When the handle or stem flat is parallel to the pipe axis, the valve is in the open position; When the handle or stem is flat with it
4. Valve locking device: In order to prevent misoperation of the valve, the valve can be locked with a lock in the fully open and fully closed position of the valve, especially when the valve installed in the field or when the process does not allow the valve to be opened or closed, in order to prevent other personnel from operating the valve incorrectly, it is very important to lock the valve position. Therefore, according to the needs of users, when designing valves, home decoration with keyhole positioning plates can meet the user's process requirements.
The main scope of application of forged flange high pressure ball valve:
Forged flange high pressure ball valve is mainly used in various high-pressure medium transportation pipelines in chemical, metallurgy, petroleum, pharmaceutical and other industries, applicable temperature: -196~450 °C; Drive mode: manual, pneumatic, electric, hydraulic, turbine, etc.; Nominal diameter: 1/2"~12"; Nominal pressure: 150LB~1500LB; Applicable medium: water, gas, oil, natural gas and acid and alkali corrosion media.
