The optimized scheme is suitable for the condition that the non-sealing surface of the component is exposed, the operation of filling gas or liquid is convenient, the filling channel is short, and the processing is convenient.
Preferably, the side plane of the component is a sealing surface, and the opening of the through hole is located on the peripheral end surface of the component. The optimization scheme is suitable for the condition that the non-sealing surface of the component is not exposed, so that liquid or gas can be conveniently filled.
Preferably, the circumferential end surface of the component is a sealing surface, and the opening of the through hole is located on the side plane of the component. This optimization scheme is fit for the butterfly valve and uses, satisfies the sealed requirement of butterfly valve.
As optimization, the number of the through holes is 3-5 distributed along the circumferential direction of the sealing groove. This optimization scheme establishes the quantity of through-hole into 3~5, is favorable to improving to fill the operating efficiency who establishes liquid or gas, fills simultaneously from a plurality of through-holes and establishes, does benefit to the homogeneity of guaranteeing the sealing washer deformation.
The utility model has the advantages that: the sealing ring is inflated and deformed by filling gas or liquid into the filling cavity, so that sealing is realized, a good sealing effect is ensured, when the two components are separated, the filling pressure is discharged through the through hole, the sealing ring retracts after being pressed, and the extrusion damage is reduced, so that the service life of the sealing ring is prolonged.
