うにするｌｒ Ｌい環状ガスケットに係るものでるる。[Detailed Description of the Invention] Even when the shut-off ball valve is placed in a large diameter pipeline and subjected to pressure, the impact of the shut-off ball valve is 1c5 between the effects. This is related to the L-shaped annular gasket, which is shown in the shape of a cut-and-break ball.

加圧して１くので確実なものとなっていく。At present, the seal inside the ball valve is created by an annular moving member that houses the main line gasket in the same space, and the block gasket is inwardly connected to the valve ball and the valve body. Manufactured in a sealed manner. This mound-shaped floating member is pressed against the valve ball by a set of springs that keep it in contact with the main bulk gasket pole, creating a seal even at zero pressure differential. However, as the working pressure increases, the pressure gradually pressurizes the main gasket due to the piston effect, so this value of 4fjm becomes reliable.

I should have put out an A. The softer the gasket, the more likely the gasket will be able to resist flaws in the ball surroundings due to imperfections in the structure or cuts or cuts caused by the working fluid being exposed to foreign matter. Can be light range. On the other hand, the basic tendency that occurs in a ball valve when subjected to a pressure difference is that the main gasket is forced out.

ならない。However, these types of gaskets do not have any of the above-mentioned features that are necessary to provide an effective seal. The circular cross-section of the gasket means that if the gasket is effectively housed within the housing circle, only a small portion of the gasket can protrude from the housing. In order to completely prevent the gasket from protruding as described above, the gasket that should be used must not be of a certain shape, but must have a rigidity that will not cause the gasket to shrink to an unparalleled extent.

る。As a result, the gasket is deformed and the V-sealing is impaired. SUMMARY OF THE INVENTION The object of the present invention is to provide an annular sealing gasket for a ball valve which eliminates the above-mentioned drawbacks, the sealing gasket being suitable for use when the valve is partially opened even if it is made of soft material. It will not be pushed out by the ejection of working fluid from the gasket seat, guarantees a seal even against partially damaged surfaces of the ball, and - simply and quickly. It can be expanded.

The gasket is flared so that it cannot be removed from the housing, and the gasket is retained in its seat by a metal retaining area. This casket is made by attaching a regular O-ring to another O-ring that is much larger in diameter than the O-ring.
