Abstract
The utility model discloses a double eccentric sealing butterfly valve, which comprises a valve plate, a valve rod, elastic valve seats, glands and a valve body. The numbers of the glands and the elastic valve seats are both two; the valve rod penetrates through the valve plate; the valve plate is movably mounted on a guide rail of the valve body; and the glands are connected with the valve body through the elastic valve seats. The double eccentric sealing butterfly valve has the advantages of convenience and quickness in opening and closing, labor saving, small fluid resistance, simple structure, small outline dimension, short structure length, small size and light weight, can be frequently operated, and is applicable to a large-caliber valve.
Description
Technical field
The utility model relates to a kind of seal butterfly valve, relates in particular to a kind of two eccentric sealed butterfly valve.
Background technique
Present butterfly valve working pressure and operating temperature range are little, and sealing is relatively poor, and keying is inconvenient to mend rapidly, fluid resistance is large, adjusting function is relatively poor, and it is larger to open and close moment, because rotating shaft both sides butterfly plate is subjected to the medium effect substantially unequal, and the direction that produces torque is identical, thereby keying is more painstaking.
Summary of the invention
The purpose of this utility model provides a kind of two eccentric sealed butterfly valve with regard to being in order to address the above problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises valve plate, valve rod, elastic seat, gland and valve body, and described valve rod passes described valve plate, and on the guide rail that is installed on described valve body that described valve plate can move, described gland is connected by described elastic seat with described valve body.
Described gland and described elastic seat are two, and the two ends of described valve body are connected with described gland by described elastic seat respectively.
The beneficial effects of the utility model are:
The utlity model has that open-close convenient is rapid, laborsaving, fluid resistance is little, can often operate, simple in structure, boundary dimension is little, and structure length is short, and volume is little, and is lightweight, is applicable to bigbore valve.
Description of drawings
Fig. 1 is the sectional view of two eccentric sealed butterfly valves described in the utility model;
1-valve plate among the figure, 2-valve rod, 3-elastic seat, 4-gland, 5-valve body.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, the utility model the utility model comprises valve plate 1, valve rod 2, elastic seat 3, gland 4 and valve body 5, and gland 4 is two with elastic seat 3, and valve rod 2 passes valve plate 1, on the guide rail that is installed on valve body 5 that valve plate 1 can move, gland 4 is connected by elastic seat 3 with valve body 5.
