Abstract
The utility model relates to a butterfly valve, which includes a valve body, a valve rod and a butterfly plate, wherein a worm-gear case is connected with the top end of the valve rod, and is provided with an operation hand wheel thereof; a bottom cover is arranged at the valve body corresponding to the bottom end of the valve rod; and a seal ring is arranged on the circumference of the butterfly plate corresponding to the valve body. The butterfly valve is characterized in that an annular concave platform is arranged on the circumference of the butterfly plate corresponding to the valve body; the sealing ring is arranged in the annular concave platform; the butterfly plate is provided with an annular pressure plate fixedly connected with the butterfly plate; and the seal ring is clamped between the butterfly plate and the annular pressure plate. Through adopting the technical scheme provided by the utility model, the butterfly valve can be assembled more conveniently.
Description
Technical field
The utility model relates to a kind of butterfly valve.
Background technique
The butterfly valve open-shut device is a discoidal butterfly plate, and the axis around himself in valve body rotates, thereby reaches the purpose that opens and closes or regulate.Normally less than 90 °, butterfly valve and butterfly bar itself do not have self-lock ability to the butterfly valve standard-sized sheet to complete shut-down, for the location of butterfly plate, on valve rod, install worm speed reducer additional.Adopt worm speed reducer, not only can make butterfly plate have self-lock ability, butterfly plate is stopped on the arbitrary position, can also improve the operating characteristics of valve.Traditional butterfly valve generally includes valve body, valve rod and butterfly plate, and valve stem tip is connected with Worm gear case; Worm gear case is provided with its operation handwheel; The corresponding valve rod bottom position of valve body is provided with bottom, and the corresponding valve body of butterfly plate periphery position is provided with seal ring, and the corresponding valve body of its butterfly plate periphery position is provided with annular groove; Seal ring is embedded in annular groove, very inconvenience of its assembling.
Summary of the invention
To the deficiency that existing technology exists, the purpose of the utility model is to provide a kind of convenient butterfly valve of assembling.
For realizing above-mentioned purpose, the utility model provides following technological scheme: a kind of butterfly valve comprises valve body, valve rod and butterfly plate; Valve stem tip is connected with Worm gear case; Worm gear case is provided with its operation handwheel, and the corresponding valve rod bottom position of valve body is provided with bottom, and the corresponding valve body of butterfly plate periphery position is provided with seal ring; It is characterized in that: the corresponding valve body of said butterfly plate periphery position is provided with annular concave platform; Said seal ring is arranged in the annular concave platform, and said butterfly plate is provided with the annular pressing plate that is fixedly connected with it, and said seal ring is clamped between butterfly plate and the annular pressing plate.
Through adopting technique scheme, during assembling, earlier seal ring is placed in the concave station, stationary platen and annular butterfly plate again, seal ring just can make things convenient for firm being clamped between butterfly plate and the annular pressing plate.
The utility model further is set to: said annular pressing plate is arranged on butterfly plate fluoran stream surface one side.
Through adopting technique scheme, make that the sealing effect of seal ring is better.
The utility model further is set to: said butterfly plate is fixedly connected through nut with annular pressing plate.
The utility model further is set to: the corresponding valve body of said valve rod position is arranged with sliding bearing.
Through adopting technique scheme, make when valve rod rotates more steady.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the utility model butterfly valve example structure figure.
Embodiment
Referring to accompanying drawing 1, the disclosed butterfly valve of the utility model comprises valve body 1, valve rod 2 and butterfly plate 3; Valve rod 2 tops are connected with Worm gear case 4; Worm gear case 4 is provided with its operation handwheel 5, and valve body 1 corresponding valve rod 2 bottom positions are provided with bottom 6, and the corresponding valve body of butterfly plate 3 peripheries 1 position is provided with seal ring 7; The corresponding valve body of said butterfly plate 3 peripheries 1 position is provided with annular concave platform; Said seal ring 7 is arranged in the annular concave platform, and said butterfly plate 3 is provided with the annular pressing plate 8 that is fixedly connected with it, and said seal ring 7 is clamped between butterfly plate 3 and the annular pressing plate 8.The utility model technological scheme butterfly plate 3 can be fixedly connected with annular pressing plate 8 in several ways, and like pin or nut etc., present embodiment preferably is set to: butterfly plate 3 is fixedly connected through nut 9 with annular pressing plate 8.Through adopting technique scheme, during assembling, earlier seal ring 7 is placed in the concave station, stationary annular pressing plate 8 and butterfly plate 3 again, seal ring 7 just can make things convenient for firm being clamped between butterfly plate 3 and the annular pressing plate 8.
The utility model technological scheme annular pressing plate 8 can be arranged on butterfly plate 3 fluoran stream surfaces, one side or relative opposite side, and for making the sealing effect of seal ring 7 better, present embodiment preferably is set to: said annular pressing plate 8 is arranged on butterfly plate 3 fluoran stream surfaces one side.
Present embodiment is further: said valve rod 2 corresponding valve bodies 1 position is arranged with sliding bearing 10.Through adopting technique scheme, make when valve rod rotates more steady.
