Abstract
The invention relates to a structure of a sealing surface of a valve clack (1), in particular to the valve clack (1) of a stop valve; a convex circle (2) is arranged in a sealing area on the bottom surface of the valve clack (1); the convex circle (2) takes on a ring shape or a round cake shape; the cross section of the convex circle (2) takes on a reversed T shape or a symmetrical L shape provided with a convex hole arranged outwards; and the convex circle (2) is sheathed with a rubber ring (3) with the shape matched with that of the convex circle (2), so that the rubber ring (3) closely clings to the sealing area of the valve clack (1) and is not needed to be fixed on the valve clack (1) by screws or in other ways. The structure of the sealing surface of the valve clack (1) is simpler in installation and implementation and lower in production and processing cost.
Description
Technical field
The present invention relates to a kind of structure of flap sealing surface, especially the flap of stop valve.
Background technique
The flap sealing surface of stop valve generally is copper material or PTFE material at present; And the latter need be fixed on the flap with screw or other fastening meanss; So the present invention provides a kind of structure of flap sealing surface, adopt the PTFE material, do not need screw or other instruments to be fixed on the flap.
Summary of the invention
For solving above-mentioned technical barrier, the invention provides a kind of structure of stop valve flap sealing surface, do not need screw or other instruments can the PTFE material be fixed on the flap.
In the sealing area of flap bottom surface, be provided with dome among the present invention, this dome is shape ringwise, and its cross section is inverted T-shaped; The rubber ring that is with on the dome; Cross section in this rubber ring is provided with the inverted T-shaped groove supporting with the dome cross section, on the flap bottom surface, is positioned at the rubber ring inboard, is provided with the convex surface of gibbosity form; Be close to rubber ring; What the cross section of said dome can also be a tang towards external symmetry in addition is L shaped, and the cross section of its rubber ring is provided with the L shaped groove supporting with the dome cross section, and its tang outwardly.
Another kind of scheme is provided in addition, and it is outside the sealing area of flap bottom surface, to be provided with dome, and this dome is round pie, and cross section is inverted T-shaped, and circle footpath, bottom is less than the internal diameter of valve seal seat.On this dome, be with rubber ring, the cross section of rubber ring is the L shaped of symmetry, and its tang inwardly.
The present invention is provided with dome at it in the sealing area of flap bottom surface; This dome is shape or round pie ringwise, and its cross section is outwardly symmetrical L shaped of inverted T-shaped or tang, the supporting rubber ring of this shape that on this dome, is with; Make rubber ring firm be close to the flap sealing area; Then need not be fixed on the flap with screw or other modes, installation is implemented simpler, and the flap cost of processing is lower.
