Abstract
The invention provides a construction of a valve clack sealing surface, and particularly relates to a construction of a valve clack (1) of a stop valve, a convex circle (2) is disposed in the bottom sealing area of the valve clack (1), the convex circle (2) is in the shape of a ring or a circular pie, and the cross section is in the shape of an inverted-T shape or a symmetrical L with a convex opening directed outward, a rubber loop (3) matched with the shape of the convex circle sleeves the convex circle, and firmly clings to the sealing area of the valve clack (1), and a screw or other modes are not needed to fix the valve clack (1), the construction of a valve clack sealing surface is advantaged by simpler installation implementation, and lower production processing cost.
Description
Technical field
The utility model 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 utility model provides a kind of structure of stop valve flap sealing surface, does 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 in the utility model, 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 utility model 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.
