Stainless steel ball valve to withstand different media and load, after passing the seal and flange valve float, a different pressure and the role of the medium can produce a certain displacement, the sealing point in the export side to meet the requirements of the health level valve A floating state can be, then the simple sealing effect can still be achieved.

The scene can carry out some tests, the workers do a good job of different media preparation, health level valve when the load reaches the original way, the ring followed by the media and pressure, will be the ball to bear the standard. Stainless steel ball valves and gate valves are of the same type, depending on the difference between the closed and rectangular centers, the rotation and the opening are different.

The special order of realization and maintenance is based on the sanitary piping of the sanitary valve as a way of changing the medium and the load can be carried out according to these three different transitions, widely used and structurally classified, stainless steel ball valve load intermediate and pressure density , As a way to filter, from the click to ensure the way.

Stainless steel ball valve design needs to consider the valve body groove and the seat of the bottom of the seal than the pressure

Stainless steel ball valve seat and the bottom of the valve body seal the pressure ratio should be on the spherical surface of the seal with the pressure than otherwise, even if the valve seat and the ball between the seal, the working fluid will be along the valve body groove and the valve seat The gap between the bottom edge of the leak.

To this end, the design of stainless steel ball valve, in addition to calculate the ball and the seat between the seal than the pressure, but also must be calculated valve seat and the bottom of the valve seat seal than the pressure. Such as the seal than the pressure is insufficient, can reduce the outer diameter of the valve seat to increase the diameter of the inside, but also in the bottom to open a few vertex angle of 60. , Explore the l-2mM triangular concentric groove to reduce the contact area, improve the sealing pressure. And the valve seat and the ball between the seal than the pressure, in general, so there is no relative movement, then the static seal, will not produce wear, it is easier to achieve the seal, the seal than the value of the former equal or slightly lower You can.
