The pneumatic three-way ball valve is usually with a rubber, nylon, and ptfe as seat sealing material, therefore its use temperature is limited by seat sealing material.As function of ball valve is on the metal sphere under the action of medium, the pressure to complete each other between the plastic seat (floating ball valves).Seat sealing under the certain contact pressure effect, elastic-plastic deformation of local region.The deformation can be made of the manufacturing precision and surface roughness of a sphere, to ensure that the ball valve sealing performance.
 
And as a result of the pneumatic three-way ball valve seat sealing usually adopt plastic, so in the choice on the structure and performance of the ball valve, want to consider the refractory of ball valve and fire prevention, especially in petroleum, chemical industry, metallurgy and other departments, the equipment and piping system of inflammable, explosive medium used in ball valve, more should pay attention to fire and fire prevention.
The common malfunction solutions pneumatic three-way ball valve
Pneumatic three-way ball valve can also be applied to light structure, low pressure by the (small) differential pressure, corrosive medium in the pipeline system.In low temperature, cryogenic device and also can choose ball valve in the pipeline system.Oxygen piping system in metallurgical industry, the need to use strict degreasing process of ball valve.Mains in the pipeline and gas transmission pipeline should be buried in the ground, the need to use full size welded ball valve.When in requires regulation performance, need to choose the special structure of ball valve with v-shaped opening.In the petroleum, petrochemical, chemical, electric power, city construction, the working temperature above 200 degrees of the piping system can choose metal to metal sealed ball valve.
 
In view of the common trouble how to solve?
 
Ball valve for a long time by material erosion, friction, causing severe impact wear, cannot meet the normal production, caused the equipment at the same time shortened lifespan.Present for ball valve wear more adopt wear-resisting material, such as ceramic materials, methods of polymer composite materials, applications have more beauty ka wah technology system.Polymer materials with excellent tackiness, super wear resistance, safe solve the disadvantages of the metal often wear, ensure the normal production of enterprise devices.And materials of ceramic materials and the unique surface enhancer, dry ground in the worst environment impact abrasion resistance and resistance to physical performance even better than that of any steel than ceramic tile, pneumatic three-way ball valve products and the types of coal is an ideal material to prevent coal product performance.
