Description

Bidirectional pressure flange-type hard seal butterfly valve
Technical field
The utility model relates to a kind of butterfly valve, and it is specifically related to a kind of Bidirectional pressure flange-type hard seal butterfly valve.
Background technique
The metal hard-sealing butterfly valve of three eccentric two-way metal hard-sealing butterfly valve solution three eccentricity structure can not realize the problem of two way sealed; Butterfly plate adopts truss structure, good rigidly, and amount of deformation is little, and valve rod adopts axis, with excentric sleeve between valve rod and butterfly plate, is linked and packed together with zero clearance, and there have taper pin to locate to be fixing; Butterfly plate good rigidly, amount of deformation is little, the sealing caused because of the gap between butterfly plate and valve rod when can avoid reverse pressure-bearing departs from, three eccentric metal hard sealed butterfly damper can be made to realize two way sealed, the positive and negative bidirectional bearing of energy, just or reverse pressure-bearing time all there is not interior leakage, but the locations of structures of existing bidirectional metal hard-sealing butterfly valve is unreasonable poorly sealed close, so be badly in need of now solving the problem.
Summary of the invention
For the problems referred to above, the purpose of this utility model proposes a kind ofly to seal Bidirectional pressure flange-type hard seal butterfly valve tight, rational in infrastructure.
A kind of Bidirectional pressure flange-type hard seal butterfly valve, be provided with a base, described base top is by a divided ring and valve body fixing seal, described body top is provided with a turbine mechanism, be provided with one to be connected interlock valve rod with turbine mechanism in the middle part of described valve body, stem bottom is through divided ring and be connected with a bearing on divided ring top and link; Be provided with a dishful of plate in the middle part of described valve body, described dish plate two ends by hex screw and pressing plate fastening, be provided with a T-shaped seal ring, the T-shape head of described T-shaped seal ring and valve body one end inner wall sealing in the gap in the middle of described dish plate and pressing plate; Described valve rod is connected interlock by a straight pin with the dish plate of side.
Described valve body and turbine mechanism are connected and fixed by a support and nut, and described valve body is sealed by a filler coordinated with valve lever clearance and a Gland with turbine mechanism link position place.
The utility model is owing to taking above technological scheme, and it has the following advantages:
Set up bearing bottom the utility model Bidirectional pressure flange-type hard seal butterfly valve, effectively alleviate the wearing and tearing of valve rod, and overall structure is simple, reasonable in design, long service life.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view of the utility model Bidirectional pressure flange-type hard seal butterfly valve.
Fig. 2 is the main TV structure schematic diagram of the utility model Bidirectional pressure flange-type hard seal butterfly valve.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
As shown in Figure 1 and Figure 2, for the structural representation of the utility model Bidirectional pressure flange-type hard seal butterfly valve, be provided with a base 1, described base 1 top is by a divided ring 2 and valve body 3 fixing seal, described valve body 3 top is provided with a turbine mechanism 15, be provided with one to be connected interlock valve rod 6 with turbine mechanism 15 in the middle part of described valve body 3, be connected with a bearing 4 on divided ring 2 top link through divided ring 2 bottom valve rod 6; Be provided with a dishful of plate 7 in the middle part of described valve body 3, described dish plate 7 two ends are fastening by hex screw 9 and pressing plate 8, are provided with a T-shaped seal ring 5, the T-shape head of described T-shaped seal ring 5 and valve body 3 one end inner wall sealing in the gap that described dish plate 7 is middle with pressing plate 8; Described valve rod 6 is connected interlock by a straight pin 12 with the dish plate 7 of side.
Described valve body 3 and turbine mechanism 15 are connected and fixed by a support 14 and nut 13, and described valve body 3 and turbine mechanism 15 link position place are sealed by one and the filler 10 of valve rod 6 Spielpassung and a Gland 11.
Set up bearing 4 bottom the utility model Bidirectional pressure flange-type hard seal butterfly valve, effectively alleviate the wearing and tearing of valve rod, and overall structure is simple, reasonable in design, long service life.
The utility model is only described with above-described embodiment; the structure of each parts, setting position and connecting all can change to some extent; on the basis of technical solutions of the utility model; all improvement of carrying out individual part according to the utility model principle and equivalents, all should not get rid of outside protection domain of the present utility model.
