Description
Technical field
The utility model relates to soft sealing butterfly valve, relates in particular to plate sealing double eccentric flange soft sealing butterfly valve.
Background technique
At present, butterfly valve, as a kind of parts that are used for realizing pipe-line system break-make and flow control, obtains applying very widely in many fields such as oil, chemical industry, metallurgy, water power.In pipe network, butterfly valve is with structure
Simply, volume is little, lightweight, open-close convenient, rapid, labour-saving advantage replacement Heavy Weight, and volume is large, the gate valve that hoisting capacity is large.
Existing butterfly valve generally all adopt body sealing and seal ring and the butterfly plate contact surface of valve seat very narrow, butterfly plate valve seat adopts welded seal seat, cannot regulate, once be contained on pipeline, closes not in place or closes excessively when running into, and all can produce leakage.Put in place even if close, in the time that concussion occurs water, valve plate swings to produce because of concussion and leaks.Make a large amount of tap water outflows, waste water source, cannot ensure the normal operation of pipe network.
Model utility content
The technical problems to be solved in the utility model is between existing butterfly plate and valve seat, sealing effect between butterfly plate and valve shaft, between valve body and valve seat is bad, run into concussion and easily produce and reveal, a kind of plate sealing double eccentric flange soft sealing butterfly valve of multistage soft seal is provided for this reason.
The technical solution of the utility model is: plate sealing double eccentric flange soft sealing butterfly valve, it comprises butterfly plate, valve shaft, valve seat and valve body, between described butterfly plate and valve shaft, be connected with taper pin nut by butterfly plate taper pin, between described butterfly plate taper pin and taper pin nut, be provided with taper pin trim ring, between described taper pin trim ring and butterfly plate taper pin, be provided with T-shaped taper pin seal ring, described butterfly plate top is provided with the butterfly plate seal ring that compresses valve seat, the surface of contact of described butterfly plate seal ring and valve seat is T-shaped, and described butterfly plate seal ring is conditioned pressing plate and regulates pressing plate clamping bolt to be pressed against butterfly plate side; Between described valve seat and valve body, be provided with valve seat and regulate trim ring, described valve seat regulates between trim ring and valve seat and is provided with T-shaped valve seat insert, and described valve seat regulates between trim ring and valve body affixed by trim ring clamping bolt.
The improvement of such scheme is between T-shaped taper pin seal ring and taper pin trim ring and T-shaped valve seat insert and valve seat regulate between trim ring and be provided with stage clip.
The beneficial effects of the utility model are that the sealing area by changing between butterfly plate seal ring and valve seat, between taper pin seal ring and butterfly plate taper pin, between valve seat insert and valve body makes it form super wide contact, butterfly plate still keeps sealing in 0～2 degree in closing process, for good sealing provides strong technical support.By regulating the degree of tightness of pressing plate clamping bolt, to butterfly plate seal ring, extruding regulates the width of butterfly plate seal ring and the contact surface of valve seat, thereby reduces valve opening and the moment of torsion of closing; In the situation that butterfly plate rubber sealing ring weares and teares, regulate the degree of tightness of trim ring clamping bolt, regulating valve seat regulates trim ring, thereby regulating valve seat, sealing is carried out to auto-compensation and realize online replacing, stage clip can alleviate between valve shaft and butterfly plate, valve seat regulates the interaction force between trim ring and valve seat, and entirety improves the working life of butterfly valve.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1 and Figure 2, the utility model comprises butterfly plate 1, valve shaft 14, valve seat 9 and valve body 13, between butterfly plate and valve shaft, be connected with taper pin nut 5 by butterfly plate taper pin 2, between butterfly plate taper pin and taper pin nut, be provided with taper pin trim ring 4, between described taper pin trim ring and butterfly plate taper pin, be provided with T-shaped taper pin seal ring 3, butterfly plate top is provided with the butterfly plate seal ring 8 that compresses valve seat, the surface of contact of butterfly plate seal ring and valve seat is T-shaped, and butterfly plate seal ring is conditioned pressing plate 6 and regulates pressing plate clamping bolt 7 to be pressed against butterfly plate side; Between valve seat and valve body, be provided with valve seat and regulate trim ring 11, valve seat regulates between trim ring and valve seat and is provided with T-shaped valve seat insert 10, and valve seat regulates between trim ring and valve body affixed by trim ring clamping bolt 12.
Butterfly plate, butterfly plate taper pin, T-shaped taper pin seal ring, taper pin trim ring, taper pin nut form transmitting assemblies; Regulate pressing plate, regulate pressing plate clamping bolt, butterfly plate seal ring and butterfly plate to form plate seal assemblies; Trim ring clamping bolt, valve seat regulate trim ring, T-shaped valve seat insert, valve seat and valve body organizator black box, have formed so multi-stage sealed system, make butterfly valve seal better effects if.By regulating the degree of tightness of pressing plate clamping bolt, to butterfly plate seal ring, extruding regulates the width of butterfly plate seal ring and the contact surface of valve seat.Regulate the degree of tightness of trim ring clamping bolt 12, regulating valve seat regulates trim ring, thus regulating valve seat and butterfly plate seal ring interface width, and then reach the object of the moment of torsion that reduces valve opening and close.
In the situation that butterfly plate rubber sealing ring weares and teares, regulate the degree of tightness of trim ring clamping bolt, regulating valve seat regulates trim ring, thus regulating valve seat carries out auto-compensation to sealing.This butterfly plate seal ring can be changed online.
