Abstract
The invention discloses a butterfly valve with an O-shaped sealing ring and a bearing, comprising a valve body, a valve rod and a butterfly plate, wherein the butterfly plate is arranged in the valve; the valve rod is arranged on the valve body in a penetrating manner and is fixedly connected with the butterfly plate in the valve body; the O-shaped sealing ring and the bearing are arranged between the valve rod and the valve body; and the O-shaped sealing ring is adopted as a sealing structure between the valve rod and the valve body, and compared with the sealing structure formed by adopting flexible graphite and a packing gland, not only are the assembly and the disassembly of operators convenient, but also the rotating torque of the valve rod also can be reduced, and the sealing performance is more reliable. In addition, the bearing is added between the valve rod and the valve body, the rotating torque of the valve rod can be further reduced, and the labor intensity of the operators is greatly reduced.
Description
Technical field
The present invention relates to a kind of valve, be specifically related to a kind of butterfly valve with O-ring seals and bearing.
Background technique
Butterfly valve is a kind of common valve, and butterfly valve mainly comprises valve body, valve rod, butterfly plate, and butterfly plate is loaded in the valve body, and valve rod is arranged on the valve body; And constitute and to be fixedly connected with butterfly plate in the valve body, present, existing reed valve; The filler that sealing between its valve rod and the valve body adopts Expanded graphite to process is usually realized, after filler is filled into, compresses through Gland again; But in actual mechanical process, the tension that Gland is pressed then can increase the moment of torsion of valve rod; The too pine that Gland is pressed is easy to generate the space again, thereby causes valve leak, makes troubles and difficulty for user's practical operation.
Summary of the invention
To the deficiency of existing technology, the invention provides a kind of sealability is better and valve rod operation moment of torsion the is less band O-ring seals and the butterfly valve of bearing.
For realizing above-mentioned purpose, the invention provides a kind of butterfly valve with O-ring seals and bearing, comprise valve body, valve rod, butterfly plate; Butterfly plate is loaded in the valve body; Valve rod is arranged on the valve body, and is fixedly connected with butterfly plate in the valve body, is provided with O-ring seals and bearing between described valve rod and the valve body.
The invention has the beneficial effects as follows: adopt O-ring seals to be used as the sealing configuration between valve rod and the valve body; Than the sealing configuration of available technology adopting Expanded graphite and Gland formation, not only be convenient to operator's loading and unloading, can also alleviate the driving torque of valve rod; And sealability is more reliable; Between valve rod and valve body, set up bearing in addition, can further reduce the driving torque of valve rod, reduced labor intensity of operating personnel widely.
The present invention can further be set to offer on the circumferential surface of said valve rod the O shape ring recess of some ccontaining O-ring seals.
The bearing that the present invention also can further be set to be provided with between said valve rod and the valve body is a single-row radial ball bearing, and described single-row radial ball bearing is loaded on the valve rod through the bearing cap fixed cover.
Description of drawings
Fig. 1 is a section of structure of the present invention.
Embodiment
The butterfly valve that has provided a kind of with O-ring seals and bearing as shown in Figure 1; Comprise valve body 1, valve rod 2, butterfly plate 3; Butterfly plate 3 is loaded in the valve body 1, and valve rod 2 is arranged on the valve body 1, and an end of valve rod 2 is fixedly connected with valve body 1 interior butterfly plate 3; The other end of valve rod 2 is connected with carries out handwheel 4; Be provided with O-ring seals 5 and single-row radial ball bearing 6 between described valve rod 2 and the valve body 1, offer the O shape ring recess 21 of some ccontaining O-ring seals 5 on the circumferential surface of said valve rod 2, described single-row radial ball bearing 6 is loaded on the valve rod 2 through bearing cap 7 fixed covers.
Adopt O-ring seals 5 to be used as the sealing configuration between valve rod 2 and the valve body 1; Than the sealing configuration of available technology adopting Expanded graphite and Gland formation, not only be convenient to operator's loading and unloading, can also alleviate the driving torque of valve rod 2; And sealability is more reliable; Between valve rod 2 and valve body 1, set up single-row radial ball bearing 6 in addition, can further reduce the driving torque of valve rod 2, reduced labor intensity of operating personnel widely.
