Abstract
The utility model relates to a built -in valve holder structure of eccentric butterfly valve, including the valve body, it has the through -hole to open in the valve body on, sets up the step along the inner wall of through -hole, the disk seat stretch into the through -hole of valve body interior and with the step butt, set up the valve plate in the disk seat, upper valve shaft 's one end stretches into the valve body cup joints with the one end of valve plate, and lower valve shaft's one end also stretches into in the valve body and cup joints in the other end of valve plate, makes the valve plate use upper valve shaft or lower valve shaft to make rotary motion as the point of rotation in the valve body, inner circle department in the disk seat still offers the recess, rabbets the PTFE who is used for with the valve plate is sealed in the recess. This sets up the step face through the inside at the valve body and has effectively realized disk seat and the cooperation of valve body and be connected, and the mounting means of disk seat and valve body step butt has been avoided need passing through a large amount of bolt fastening disk seats and valve body in the past, has not only reduced workman's intensity of labour, has still improved assembly efficiency, has shortened the assemble duration.
Description
Technical field
This utility model relates to valve body apparatus field, particularly relates to the built-in valve seat construction of eccentric-butterfly-valve.
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.The installation direction being related to valve seat at present in the assembling process of existing butterfly valve structure is to be embedded in from valve body, then a large amount of bolt is along the circumferential direction utilized to make valve seat be fixed on valve body, above-mentioned mounting means is wasted time and energy, not only increase the labor intensity of workman, also improve installation time, make efficiency of assembling be substantially reduced.
Utility model content
The applicant, for above-mentioned existing issue, has carried out Improvement, it is provided that a kind of built-in valve seat construction of eccentric-butterfly-valve, utilizes this structure to save the assembling mode in the past wasted time and energy, substantially increases efficiency of assembling.
The technical scheme that this utility model adopts is as follows:
A kind of built-in valve seat construction of eccentric-butterfly-valve, including valve body, has through hole on described valve body, and the inwall along described through hole offers step, and valve seat stretches in the through hole of valve body and abuts with step, arranges valve plate in described valve seat.
Its further technical scheme is in that:
Described valve body is stretched in one end of upper valve shaft and the one end with valve plate is socketed, and one end of lower valve shaft is also stretched in described valve body and is socketed in the other end of valve plate, and making the above valve shaft of described valve plate or lower valve shaft is that the point of rotation rotates in valve body；Also offering groove in the inner ring place of described valve seat, in described groove, interlocking is for the PTFE with valve plate sealing.
The beneficial effects of the utility model are as follows:
This utility model simple in construction, easy to use, by effectively achieving being connected of valve seat and valve body at the inside setting table terrace of valve body, the mounting means that valve seat abuts with valve body step avoids and requires over a large amount of bolt fixed valve base and valve body in the past, not only reduce the labor intensity of workman, also improve efficiency of assembling, shorten installation time, the sealing in order to realize valve shaft outer ring of the layout of disc spring, apply pressure when stress to filler.

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, the built-in valve seat construction of eccentric-butterfly-valve includes valve body 6, through hole is had on valve body 6, inwall along through hole offers step 601, valve seat 7 stretches in the through hole of valve body 6 and abuts with step 601, arranges valve plate 9 in valve seat 7, and valve body 6 is stretched in one end of upper valve shaft 12 and the one end with valve plate 9 is socketed, one end of lower valve shaft 11 is also stretched in valve body 6 and is socketed in the other end of valve plate 9, makes valve plate more than 9 valve shaft 12 or lower valve shaft 11 rotate in valve body 6 for the point of rotation；Also offering groove in the inner ring place of valve seat 7, in groove, interlocking is for the PTFE8 (PTFE is politef) with valve plate 9 sealing.Also coordinate gland 1 in one end of valve body 6, in the periphery of upper valve shaft 12, gland 1 is for realizing and the sealing of upper valve shaft 12.In the inside of valve body 6, also it is socketed upper neck bush 5 along the periphery of upper valve shaft 12, between the inwall and the periphery of upper valve shaft 12 of upper neck bush 5, also order arranges one group of disc spring 2, packing press ring 3, filler 4 and sealing ring 13, and above-mentioned packing press ring 3 is for providing carrying stress surface to the disc spring 2 of stress deformation.The sealing arranging upper valve shaft 12 outer ring of realization of disc spring 2, it is prevented that medium flows out from axis hole, applies pressure when stress to filler 4.
As in figure 2 it is shown, in valve body 6, be also provided with sealing ring 13 along the outer ring of upper neck bush 5.In valve body 6, the periphery along lower valve shaft 11 is also provided with multiple sealing ring 13.In the junction of lower valve shaft 11 and valve plate 9 other end, also set up lower neck bush 10 in the periphery of lower valve shaft 11.
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.
