Abstract
The utility model relates to a biplate body butterfly valve structure of removable disk seat, include each other last valve body and lower valve body for connecting, in go up the valve body and install the disk seat down between the valve body, in the periphery suit elasticity back of disk seat, upper valve shaft 's one end runs through the valve body and is connected with the valve plate, lower valve shaft's one end with the valve body is connected down, lower valve shaft's the other end also is connected with the valve plate, in the top of going up the valve body still sets up flange portion, flange portion with it is integrative to go up valve body connection formation, in the top of flange portion is still opened slottedly, in dustproof sealing ring, axle sleeve, dish spring, drilled packing ring and sealing washer are still cup jointed in proper order to upper valve shaft, lower valve shaft's periphery. The utility model discloses simple structure, convenient to use, its cooperation that can satisfy different material disk seats and valve body utilizes the elasticity back to support and be fixed for the disk seat, makes disk seat non -deformable, has improved the life of disk seat greatly, has guaranteed stable sealing and the moment of torsion.
Description
Technical field
This utility model relates to valve body equipment, particularly relates to the biplate body butterfly valve structure of a kind of valve with changeable valve seat。
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。In current existing butterfly valve structure, the valve seat of a kind of size is only applicable to the valve body of single specification, in order to meet the valve body of the installation needs bearing different size of various sizes of valve seat, not only increases the labor intensity of workman, also add enterprise's production cost simultaneously。
Utility model content
The applicant, for above-mentioned existing issue, has carried out Improvement, it is provided that the biplate body butterfly valve structure of a kind of valve with changeable valve seat, and it achieves the installation of unlike material valve seat and valve body, reduces the labor intensity of workman, reduces the Productive statistics cost of enterprise。
The technical scheme that this utility model adopts is as follows:
The biplate body butterfly valve structure of a kind of valve with changeable valve seat, including the upper valve body connected each other and lower valve body, installs valve seat between described upper valve body and lower valve body, is set with elastic backrest in the periphery of described valve seat；One end of upper valve shaft is run through upper valve body and is connected with valve plate, and one end of lower valve shaft is connected with described lower valve body, and the other end of described lower valve shaft is also connected with valve plate；Also set up flange portion in the top of described upper valve body, described flange portion and described upper valve body are connected to form one, and also have groove in the top of described flange portion；Periphery also order in described upper valve shaft, lower valve shaft is socketed dust-proof seal ring, axle sleeve, disc spring, packing ring and sealing ring。
The beneficial effects of the utility model are as follows:
This utility model simple in construction, easy to use, it can meet coordinating of unlike material valve seat and valve body, utilizes elastic backrest to support to valve seat and fixing, makes 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 layout of disc spring makes to exist between itself and valve seat elastic compaction, substantially increases sealing。

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, Figure 2 and shown in Fig. 4, the biplate body butterfly valve structure of a kind of valve with changeable valve seat includes the upper valve body 11 that connects each other and lower valve body 13, and upper valve body 11 is affixed by bolt 12 with lower valve body 13。Installing valve seat 7 between upper valve body 11 and lower valve body 13, be set with elastic backrest 8 in the periphery of valve seat 7, valve seat 7 adopts PTFE material to make。One end of upper valve shaft 51 is run through upper valve body 11 and is connected with valve plate 10, and one end of lower valve shaft 52 is connected with described lower valve body 13, and the other end of described lower valve shaft 52 is also connected with valve plate 10。Also set up flange portion 2 in the top of upper valve body 11, flange portion 2 and upper valve body 11 are connected to form one, and also have groove 1 in the top of flange portion 2；Periphery also order socket dust-proof seal ring 3, axle sleeve 4, disc spring 6, packing ring 14 and sealing ring 9 in above-mentioned upper valve shaft 51, lower valve shaft 52。Also set up flange portion 2 in the top of upper valve body 11, flange portion 2 and upper valve body 11 are connected to form one, and also have groove 1 in the top of flange portion 2。
Concrete installation process of the present utility model is as follows:
As it is shown on figure 3, the valve seat 7 of above-mentioned PTFE material can be replaced by rubber valve seat 15, it is achieved thereby that the replacing of unlike material valve seat。
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。
