Abstract
The utility model relates to a take earhole butterfly valve structure, take earhole butterfly valve structure, including the valve body, in the top of valve body sets up flange portion, in flange portion still outwards extends with the junction of valve body and forms a pair of flange, in set up the earhole in the flange. The utility model discloses simple structure, convenient to use can realize hanging customer's description or engineering code through the design earhole, prevent that the design beauty and practicability of the unable model's of differentiation problem, earhole from appearing in the customer.
Description
Technical field
This utility model relates to valve body field, particularly relates to band earhole butterfly valve structure。
Background technology
Butterfly valve is again flap valve, it it is the adjustment valve of a kind of simple in construction, can be used for the butterfly valve of the on-off control of low pressure pipeline medium and refer to that closure member (flap or butterfly plate) is disk, rotate a kind of valve reaching to open and close around valve shaft, valve can be used for controlling the flowing of all kinds fluids such as sky gas and water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium。Current existing butterfly valve structure valve seat when life-time service is yielding, it is impossible to ensure sealing and the moment of torsion of butterfly valve structure, does not simply fail to hanging client's description or engineering code simultaneously at existing butterfly valve structure, also makes client cannot be distinguished by butterfly valve model。
Utility model content
The applicant is for above-mentioned existing issue, carry out Improvement, a kind of band earhole butterfly valve structure is provided, client's description and the hanging of engineering code is not only achieved by designing earhole, increase elastic backrest simultaneously, utilize elastic backrest to support to valve seat and fixing, make valve seat be unlikely to deform, substantially increase the service life of valve seat, it is ensured that stable sealing and moment of torsion。
The technical scheme that this utility model adopts is as follows:
Band earhole butterfly valve structure, including valve body, arranges flange portion in the top of described valve body, further extends outward formation pair of flanges in the junction of described flange portion Yu valve body, offer earhole in described flange。
Its further technical scheme is in that:
Valve seat is arranged in valve body, installs valve plate in described valve seat, and one end of upper valve shaft is connected with valve plate, and one end of lower valve shaft is also connected with described valve plate。
The beneficial effects of the utility model are as follows:
This utility model simple in construction, easy to use, hanging client's description or engineering code can be realized by designing earhole, prevent the problem that product type occurs cannot be distinguished by client, the practicality that is designed beautifully of earhole, additionally by increasing hard backrest on valve seat, utilize hard backrest to support to valve seat and fixing, make valve seat be unlikely to deform, substantially increase the service life of valve seat, it is ensured that stable sealing and moment of torsion。

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described。
As shown in Figure 1 and Figure 2, band earhole butterfly valve structure includes valve body 7, arranges flange portion 701 in the top of valve body 7, and flange portion 701 and valve body 7 are connected to form one。Further extend outward formation pair of flanges in the junction of flange portion 701 with valve body 7, in flange, offer earhole 14。Valve seat 8 is arranged in valve body 7, installs valve plate 9 in valve seat 8, and one end of upper valve shaft 1 is connected with valve plate 9, and one end of lower valve shaft 11 is also connected with valve plate 9。It is arranged symmetrically with centered by the above valve shaft 1 of above-mentioned flange。As in figure 2 it is shown, also install back-up ring 2 in flange portion 701, back-up ring 2 is fixed by screw 3。Also setting up V-type circle 4 and the first lining 6 between upper valve shaft 1 and valve body 7, the first lining 6 is sleeved on the periphery of valve shaft 1。As in figure 2 it is shown, also install the second lining 10 in the periphery of lower valve shaft 11, also setting up the first O 5 in the junction of lower valve shaft 11 with valve seat 8, the other end at above-mentioned lower valve shaft 11 is also connected with plug screw 12, and the junction of plug screw 12 and valve body 7 also sets up the second O 13。Also setting up hard backrest 15 on above-mentioned valve seat 8, this hard backrest 15 vulcanizes on valve seat 8。
Above description is to explanation of the present utility model, is not the restriction to utility model, and this utility model limited range is referring to claim, and when without prejudice to basic structure of the present utility model, this utility model can do any type of amendment。
