Pneumatic Jacketed Wafer Type Ball Valve

Wafer type jacketed ball valve, as the name suggests, it has a thermal insulation function, it can keep the medium worm or cold. There is a layer of cavity outside the valve body, and hot water or steam can be injected to maintain the temperature of the channel medium and prevent the medium from freezing. Its media include grease, benzene, sulfur, chocolate,

Fatty alcohol, asphalt, wax, polyurethane, resin. Wafer type jecketed ball valve is a common type of valve, it has insulation performance and good sealing performance, widely used in petroleum, chemical, electric power, metallurgy and other industries.

The structures of wafer jacketed ball valve:

The wafer jacketed ball valve is composed of valve body, valve cover, valve ball, valve stem, sealing ring, insulation material, etc. Among them, the valve body and the valve cover are connected by a spherical surface, the valve ball is controlled by the valve stem, the sealing ring is made of elastic material, and the thermal insulation material is wrapped between the valve body and the valve cover to play a thermal insulation role.

The working principle of the wafer jacketed ball valve:

The working principle of the wafer jacketed ball valve is to control the switch of the valve ball by rotating the valve stem, so as to achieve fluid control. When the stem rotates, the ball also rotates, changing the size of the clearance between the ball and the seat, thereby controlling the flow of fluid. At the same time, the elasticity of the sealing ring can also ensure the sealing performance of the valve.

The advantages of the wafer jacketed ball valve:

1. Good thermal insulation performance: The wafer jacketed ball valve is wrapped in thermal insulation material between the valve body and the valve cover, which can effectively maintain the temperature of the fluid, so as to ensure the stability of the fluid.

2. Good sealing performance: The wafer jacketed ball valve uses the sealing ring as the sealing material, which has good elasticity and corrosion resistance, and can effectively prevent fluid leakage.

3. Easy to operate: The wafer jacketed ball valve uses the rotating stem control valve ball switch, simple and convenient operation, can quickly achieve fluid control.

4. Wide range of application: The wafer jacketed ball valve is suitable for a variety of fluid media, including corrosive media and high temperature and high pressure media.
