How to solve the forged steel valve grease problem

Release date:2015-05-05    The number of clicks:

Grease gun refueling operation personnel, low temperature valve selection valve and grease coupling method after fat injection operation. There are two kinds of forged steel gate: on the one hand, less fat less grease, sealing surface accelerated wear due to lack of lubricant. On the other hand note fat too much, resulting in waste. Is not in accordance with the type of types of valves, the valve sealing capacity of different calculations. Can be calculated valve size and type of seal capacity, and then injected into a reasonable amount of grease.

The structure characteristics of forged steel valves

1) forged steel valve has good heat insulation properties, in addition to reducing insulation valve, the valve diameter and the diameter of one to medium linear flow resistance is small, can effectively reduce the heat loss of the medium in pipelines, therefore, liquid medium on easy solidification, high viscosity with excellent performance.

2) the self cleaning forged steel valve sealing structure. When the ball roll off the seat when the fluid in the pipeline along the sealing surface of the sphere into 360 degrees evenly through, not only eliminates the high speed fluid on the seat of local scour, also washed away the sediment on the sealing face, achieve the purpose of cleaning.

3) wedge-shaped seal structure. Forged steel valve stem is provided by the mechanical force, the ball seat on the wedge pressure to seal the valve seal from the impact of changes in pipeline pressure under various working conditions to ensure reliable sealing performance are.
