Posted by Food and beverage industry has the characteristics of large output, wide market scope, complex sales network, and complex supply chain structure. In order to effectively monitor the circulation of food and beverage products and avoid large-scale product quality accidents, it is necessary to establish a complete product quality traceability system and a rapid early warning system.
Sanitary ball valves are widely used in petroleum refining, long-distance pipeline, chemical industry, paper making, pharmaceutical, water conservancy, power, municipal, steel, and other industries. It has the action of rotating 90 degrees, the cock body is a sphere, with a circular hole or passage through its axis.
Pneumatic ball valve has a compact structure, reliable sealing, simple structure, convenient maintenance, sealing surface and spherical surface are often in the closed state, not easy to be eroded by media, easy to operate and repair, suitable for milk, water, solvent, acid, and natural gas and other general working media, mainly used for cutting off or connecting the medium in the pipeline, also used for fluid regulation and control.
Compared with other types of sanitary valves, pneumatic ball valves have the following advantages: angular stroke output torque, fast opening, stability and reliability, wide application, etc.
1. Thrust bearing reduces the friction moment of the valve stem and makes the stem operate smoothly and flexibly for a long time.
2. Anti-static function: Spring is set between sphere, valve stem, and valve body, which can derive the static electricity generated during the switching process.
3. Long service life: Because PTFE and other materials have good self-lubrication and little friction loss with the ball, the service life of the pneumatic ball valve is long.
4. Low fluid resistance: Pneumatic ball valves are the least fluid resistance of all valve classifications, and even shrinkage pneumatic ball valves have relatively small fluid resistance.
5. Reliable Stem sealing: because the stem is only rotated but not lifted, the packing seal of the stem is not easy to be destroyed, and the sealing ability increases with the increase of the pressure of the medium.
6. Good seating performance of valve seat: The sealing ring made of elastic materials such as PTFE is easy to seal, and the sealing capacity of the pneumatic ball valve increases with the increase of medium pressure.
