Abstract

The utility model discloses a rubber sealing butterfly valve. The rubber sealing butterfly valve comprises a valve body and a valve plate, wherein a sealing pair consisting of a valve body rubber sealing ring and a valve plate rubber sealing ring is arranged between the valve body and the valve plate, the periphery of the valve plate is provided with a radial groove, a part of the valve plate rubber sealing ring is positioned in the radial groove, the inner walls of two side surfaces of the radial groove are machined to be in a sawtooth shape, the valve plate rubber sealing ring is positioned in the radial groove, two side surfaces of the valve plate rubber sealing ring, which contact with the inner walls of the two side surfaces of the radial groove, are machined to be sawtooth-shaped, two sawtooth-shaped side surfaces of the valve plate rubber sealing ring are matched with the inner walls of the two sawtooth-shaped side surfaces of the radial groove when the part of the valve plate rubber sealing ring is placed in the radial groove, one side surface of the radial groove is provided with a removable pressure plate, and a gap is reserved between the top of the inner side of the valve plate rubber sealing ring and the bottom of the radial groove. Due to the rubber sealing butterfly valve adopting the structure, the valve plate sealing ring can be assembled and disassembled conveniently.

Description

A kind of rubber seal butterfly valve
Technical field
The utility model relates to a kind of rubber seal butterfly valve.
Background technique
Butterfly valve is used for the particularly conveyance conduit of water of fluid, butterfly valve has valve body, rotatable valve plate is arranged in valve body, between valve body and valve plate, sealing pair is arranged, sealing pair is by the valve plate sealing ring and the valve seal ring mix proportion that is set on the valve body inner circumference that are set on the valve plate excircle, and the valve plate sealing ring of rubber seal butterfly valve is made with rubber material.In prior art, the valve plate rubber seal ring of rubber seal butterfly valve is that the location is connected on the valve plate excircle, the valve plate excircle is provided with radial groove radially, radial groove comprises bottom land and two sides, the part of valve plate rubber seal ring is placed in groove, the inside top of valve plate rubber seal ring contacts with the bottom land of radial groove, the problem that above-mentioned rubber seal butterfly valve of the prior art exists is: will be a bit larger tham the size of radial groove width due to the thickness of valve plate rubber seal ring, the installation and removal of valve plate rubber seal ring are all very difficult.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of valve plate rubber seal ring and mounts and dismounts all relatively easy rubber seal butterfly valve.
for solving the problems of the technologies described above, a kind of rubber seal butterfly valve of the utility model, comprise valve body, rotatable valve plate is arranged in valve body, has sealing pair between valve body and valve plate, sealing pair is by the valve plate rubber seal ring and the valve seal ring mix proportion that is arranged on described valve body inner circumference that are arranged on described valve plate excircle, described valve plate excircle is provided with radial groove, radial groove comprises bottom land and two sides, the part of described valve plate rubber seal ring is positioned at radial groove, a side of described radial groove is detachable pressing plate, this detachable pressing plate is loaded on described valve plate by clamping bolt.
Adopt the rubber seal butterfly valve of said structure, because a side of described radial groove is detachable pressing plate, this detachable pressing plate is loaded on described valve plate by clamping bolt, therefore be that installation valve plate sealing ring or dismounting valve plate sealing ring are all very convenient, as long as screw off clamping bolt, take off pressing plate and just be easy to mount and dismount valve plate sealing ring.
As further improvement of the utility model, two side inner walls of described radial groove are processed to zigzag fashion, described valve plate rubber seal ring is positioned at this radial groove and two side inner walls of this radial groove contacted two sides also are processed to zigzag fashion, when the part of described valve plate rubber seal ring was placed in described radial groove, two the zigzag fashion side inner walls in the side of two zigzag fashions of described valve plate rubber seal ring and described radial groove matched.
Further improve as of the present utility model, have the gap between the inside top of described valve plate rubber seal ring and the bottom land of radial groove.
The mode that adopts two of two of valve plate sealing rings zigzag fashion side and radial grooves zigzag fashion side to match more is conducive to the part of valve plate sealing ring in radial groove and locates.Has the gap between the inside top of described valve plate rubber seal ring and the bottom land of radial groove, when butterfly valve cut-off valve plate rubber seal ring is squeezed and can be radially during the medium punching press extends to the gap between the bottom land of the inside top of valve plate rubber seal ring and radial groove, can alleviate the elastic fatigue that the valve plate rubber seal ring uses generation for a long time, extend the working life of valve plate rubber seal ring.
Description of drawings
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the main sectional structure schematic diagram of a kind of rubber seal butterfly valve of the utility model.
Fig. 2 is I place structure enlarged diagram in Fig. 1.
Fig. 3 is II place structure enlarged diagram in Fig. 2.
Embodiment
referring to Fig. 1-Fig. 3, a kind of rubber seal butterfly valve of the utility model, comprise valve body 1, rotatable valve plate 2 is arranged in valve body 1, 2 of valve body 1 and valve plates have sealing pair, sealing pair is by the valve plate rubber seal ring 3 and valve seal ring 4 mix proportions that are arranged on described valve body 1 inner circumference that are arranged on described valve plate 2 excircles, described valve plate 1 excircle is provided with radial groove 5, radial groove 5 comprises bottom land 6 and two sides 7, 8, the part of described valve plate rubber seal ring 3 is positioned at radial groove, a side 7 of described radial groove 5 is detachable pressing plate, this detachable pressing plate is loaded on described valve plate 2 by clamping bolt 9.
Two sides 7 of described radial groove 5,8 inwalls can be to be processed to zigzag fashion, described valve plate rubber seal ring 3 is positioned at this radial groove 5 and this radial groove 5 two sides 7,8 inwalls contacted two sides 10,11 and also correspondingly is processed to zigzag fashion, when the part of described valve plate rubber seal ring 3 is placed in described radial groove 5 when interior, match with 5 two of described radial grooves zigzag fashion side, 7,8 inwalls in the side 10 of 3 two zigzag fashions of described valve plate rubber seal ring, 11.
Can leave gap 12 between the bottom land 6 of the inside top of described valve plate rubber seal ring 3 and radial groove 5.
