(Summary description)The pneumatic ball valve 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. Pneumatic ball valves are mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. The pneumatic ball valves designed with V-shaped openings also have a good flow adjustment function. The pneumatic butterfly valve is different from the pneumatic ball valve. It is a valve that uses a disc-type opening and closing member to reciprocate about 90° to open, close and adjust the fluid channel.

Information

The pneumatic ball valve 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. Pneumatic ball valves are mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. The pneumatic ball valves designed with V-shaped openings also have a good flow adjustment function. The pneumatic butterfly valve is different from the pneumatic ball valve. It is a valve that uses a disc-type opening and closing member to reciprocate about 90° to open, close and adjust the fluid channel.

    Pneumatic ball valve features: blockage and secretion: When the valve is closed, the upstream and downstream valve seats block the liquid, and the stagnant in the cavity of the valve body can be secreted through the secretion device. Automatic pressure relief structure: When the pressure in the side cavity is abnormally increasing, the medium in the middle cavity can rely on its own thrust to push the valve seat to automatically release the pressure, and then ensure the safety of the valve lift. Reliable sealing of the valve stem: The valve stem adopts a bottom-mounted structure with an inverted seal. The sealing force of the inverted seal increases with the increase of medium pressure, so the reliable sealing of the valve stem can be ensured. Moreover, when the valve stem is abnormally increased in pressure, The valve stem will not spray out. Fireproof structure: According to the working conditions and user needs, the ball valve can be planned as a fireproof structure. Anti-static structure: When the valve is operated, due to the friction between the ball and the valve seat, electrostatic charges will be generated and accumulated on the ball. In order to prevent the occurrence of static sparks, an electrostatic device is specially installed on the valve to prevent the accumulation of electricity on the ball. The charge is derived.

    The characteristics of the pneumatic butterfly valve: the circular butterfly plate that rolls with the valve can open and close, and the pneumatic valve that completes the activation action is mainly used as a shut-off valve. According to the structural characteristics of the pneumatic butterfly valve, it can also be planned to have the function of dispatching or segment valve and dispatching. , Nowadays, the use of butterfly valves in low-pressure large and medium-diameter pipelines is constantly increasing. In fact, many equipment have pneumatic butterfly valves, especially on pipelines, but we must not underestimate them. However, many people have heard of pneumatic butterfly valves for the first time, and they do not understand its advantages and disadvantages. But it doesn't matter, the editor will introduce us the advantages and disadvantages of pneumatic butterfly valves.
