How To Provide Sealing Performance For High Platform Ball Valves?

How to provide Sanitary Ball Valve sealing?
For high platform ball valves, sealing is an important guarantee for safe production. So how can we improve the sealing of high platform ball valves? High platform ball valve manufacturers will show you how.
The general preload pressure ratio of the sealing seat of the high platform ball valve is about 0.1 nominal pressure, but not less than 1.02mpa. The adjustment of the preload pressure ratio of the sealing seat is determined by adjusting the thickness of the gasket. The thickness error will affect the tightness of the entire high platform ball valve, so reasonable adjustment is the key. Therefore, in order to improve this situation, a sealing seat with elastic effect is used. The preload pressure ratio value does not need to be changed by adjusting the thickness, and the preload pressure ratio can be compensated within the elastic range to maintain the extension of the service life of the high platform ball valve.
The appropriate preload pressure ratio can extend the service life of the high platform ball valve and enhance the safety of the stainless steel high platform ball valve during operation. In a case where the working pressure of the medium is strong, it is necessary to accurately select the pre-tightening pressure ratio of the sealing seat. If the pre-tightening pressure ratio is low, the tightness of the high platform ball valve will be reduced; if the pre-tightening pressure ratio is high, it will cause the sealing seat to deform, affecting the kinetic energy of the high platform ball valve, resulting in a lack of tightness.
During the use of the high platform ball valve, the effect is affected by the sealing, so the sealing is very important for the valve, so how can we improve the sealing of the platform ball valve?
Generally speaking, the main factors affecting the sealing of the high platform ball valve are the selection of materials and the form of the mechanism.
1. The tightness of the high platform ball valve is also related to its structure. Different structures have different tightness effects. Selecting suitable tightness materials and reasonable structural requirements can obtain the high tightness of stainless steel high platform ball valves.
2. The general pre-tightening pressure ratio value of the sealing seat of the high platform ball valve is about 0.1 nominal pressure, but not less than 1.02mpa. The adjustment of the sealing seat preload specific pressure value is determined by adjusting the thickness of the gasket. The thickness error will affect the tightness of the entire stainless steel high platform ball valve, so reasonable adjustment is the key.
