Description
Technical field
The utility model relates to a kind of butterfly valve, and it is specifically related to the special butterfly valve of a kind of explosion-proof type gas.
Background technique
Explosion-proof butterfly valve is simple with structure, and sealing is reliable, open light, the life-span long, the advantage such as easy to maintenance is widely used on the various pipeline of the system such as plumbing, structural fire protection, especially in fire main.Existing explosion-proof butterfly valve generally adopts triple eccentric seat sealing system, and valve seat and butterfly plate, almost without wearing and tearing, have the sealing function closing tighter and tighter.Seal ring selects stainless steel to make, and has the two-fold advantage of metal hard-sealing and elastic packing, no matter when low temperature and high temperature, all has excellent sealability, has the features such as corrosion-resistant, long service life.But also do not have at present a explosion-proof butterfly valve for gas tube particular design, 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 of special butterfly valve of explosion-proof type gas for improving gas tube or valve Security.
The special butterfly valve of a kind of gas, be provided with a base, described base is fixed by socket head screw and valve seal, a dishful of plate is provided with in the middle part of described valve body, described dish plate two ends by hex screw and pressing plate fastening, described dish plate and pressing plate are by seal ring and valve body one end inner wall sealing, and 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, 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:
The special butterfly valve overall structure of the utility model explosion-proof type gas designs for gas tube, and structure is simple, reasonable in design, long service life.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view of the special butterfly valve of the utility model explosion-proof type gas.
Fig. 2 is the main TV structure schematic diagram of the special butterfly valve of the utility model explosion-proof type gas.
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 special butterfly valve of the utility model explosion-proof type gas, be provided with a base 1, described base 1 seals fixing by socket head screw 2 and valve body 3, a dishful of plate 9 is provided with in the middle part of described valve body 3, described dish plate 9 two ends are fastening by hex screw 6 and pressing plate 5, described dish plate 9 and pressing plate 5 are by seal ring 4 and valve body 3 one end inner wall sealing, described valve body 3 top is provided with a turbine mechanism 15, be provided with one to be connected interlock valve rod 8 with turbine mechanism 15 in the middle part of described valve body 3, valve rod 8 is connected interlock by a straight pin 7 with the dish plate 9 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 8 Spielpassung and a Gland 11.
The special butterfly valve overall structure of the utility model explosion-proof type gas designs for gas tube, and 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.
