Countermeasures for improving the sealing function of stainless steel ball valves

What are the components of a stainless steel sphere

The surface of the stainless steel sphere is a sloping surface, which is called a curved surface.

A ball is similar to a circle and also has a core called the center of the ball.

The circle obtained by cutting a surface through a plane passing through the center of a sphere is called a small circle, and the circle obtained by cutting a cross-section that does not pass through the center of a sphere is called a circle.

On a surface, the minimum length of the connecting line between two points is the length of the poor arc of the small circle between these two aspects, and the length of the plastic extruder bearing between these two aspects. The chord length of the sphere is called the spherical distance between the two points.

What standards can reflect the sealing performance of stainless steel ball valves and whether the bearings of Qingyuan plastic extruders are good or bad? We all know that the key function of the vast majority of valves is to disconnect and connect the transportation of media. In order to ensure that media leakage is not easy to occur, the sealing performance must be good. Leak prevention is a major technical indicator value of valves. According to the following common problems with Qingyuan plastic extruder bearings, the bearing layer of Qingyuan plastic extruder must be addressed:

The stainless steel ball of the valve has three different sealing points: (1) the joint between the filling material and the valve seat (2), the joint between the stainless steel ball and the valve cap (3), and the contact point between the protruding surface of the high-pressure gate valve and the opening and closing parts

The first and second leaks are known as exposure, which leaks the medium inside the valve to the outer side of the Qingyuan plastic extruder bearing, contaminating the bearing environment of the Qingyuan plastic extruder and causing unexpected safety incidents. It is definitely not allowed to have any harmful or flammable media on the bearings of Qingyuan Plastic Extruder. The stainless steel ball must have very good sealing.

The third leakage is called air leakage, which is caused by the lack of relevant bearings on the Qingyuan plastic extruder when it is turned off, and will seriously affect the actual interception effect of the valve.
