to review the working process of the stainless steel valve opening and closing

stainless steel valves can be used in various fields, also because of its special performance: the switch is lightweight, small size, compact structure, easy operation and maintenance, applicable to water, solvent, acid and gas, such as general work medium, but also is suitable for the working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene.

a, stainless steel valve opening process

1. In the closed position, stainless steel ball valve ball by stem pressure effect, so as to press on the seat.

2。 Stem continue to ascend, and valve stem guide pin of interaction in the spiral groove, the sphere began to rotate without some friction.

3。 To full open position, the stainless steel ball Industrial Valves stem ascending to limit position, the ball will spin to the full open position.

4。 When the handwheel counterclockwise rotation of cast steel ball valve, the movement direction of the Industrial Valves stem with its contrary, cast steel flange ball valve at the bottom of the angular plane make the ball off the seat.

2, stainless steel valve closing process

1. Is closed, a sphere has been without contact with the valve seat rotated 90 & deg; 。

2。 Closing, rotating the handwheel clockwise, stem began to drop and the ball left seat begin to spin.

3。 Continue to rotate the handwheel, the valve stem is embedded in the spiral groove on the role of the guide pin, make the stem and ball rotation at the same time 90 & deg; 。

4。 Hand wheel rotation of the last few laps, stem mechanically wedge Angle at the bottom of the plane to the oppression of a sphere, make its strong pressure on the seat, to completely seal.

stainless steel valve opening and closing process is important link when using, in the process of opening and closing should be pay attention to safety, guarantee the stability of the stainless steel valves and the safety of the operator.

There are many issues that affect cast iron valve, which has led to the need of getting specialists trained in certain areas so as to handle all issues that may arise as well as flow control valve products that can solve os gate valve problems.
