Specific implementation mode
To make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, below
In conjunction with specific implementation mode, the utility model is expanded on further.
As shown in Figs. 1-3, a kind of double eccentric flange butterfly valves, including valve body 1, upper valve rod 2, lower valve rod 3 and main valve plate 4, valve
The middle part on 1 top of body is mounted on the bottom end of 1 inner wall of valve body, the bottom of upper valve rod 2 with the interspersed connection in the middle part of upper valve rod 2, lower valve rod 3
Connection is interted in portion and the top of lower valve rod 3 with the top and bottom of main valve plate 4 respectively, and the both ends of valve body 1 are fixed with port
The both sides of flange 5, main valve plate 4 are fixedly connected with the side of two pieces of auxiliary valve plates 7 by four brute springs 6 respectively, main valve plate 4
Edge and the edges of two pieces of auxiliary valve plates 7 contacted with the inner wall of valve body 1, the inside of the inside of main valve plate 4 and two pieces of auxiliary valve plates 7
It is fixed with several reinforcing ribs 8.
Wherein, the middle part of valve body 1 is ball valve, prevents two pieces of auxiliary valve plates 7 from interfering the rotation of main valve plate 4.
Wherein, the both sides of 3 bottom of the both sides of 2 bottom of upper valve rod and lower valve rod are equipped with several keys 10,4 top of main valve plate
Middle part and the middle part of bottom end offer the mounting hole that the size of size and upper valve rod 2 and the size of lower valve rod 3 match respectively
11, the both sides of 11 inner wall of each mounting hole are provided with the keyway to match with key 10, several keys 10 are inserted into several keys respectively
The inside of slot improves the stability connected between upper valve rod 2 and lower valve rod 3 and main valve plate 4 by the cooperation of key 10 and keyway,
Prevent 4 stress of main valve plate is excessive from being slided between upper valve rod 2 and lower valve rod 3.
Wherein, the outside of two pieces of auxiliary valve plates 7 is fixed with wearing layer 9, and butterfly valve can be prevented for a long time by wearing layer 9
Abrasion occurs using rear auxiliary valve plate 7 to leak.
Wherein, four brute springs 6 have a rectangular shape arrangement, and four 6 stress of brute spring is made to keep balance.
It should be noted that the utility model is a kind of double eccentric flange butterfly valves, when specific works, end can be passed through first
Butterfly valve is mounted on pipeline by mouth flange 5, then can drive main valve plate 4 and two pieces of 7 turns of auxiliary valve plates by rotating upper valve rod 2
It is dynamic, when butterfly valve is in closing dress state, one of auxiliary valve plate 7 is first passed through at this time and stops high-pressure water body, when high-pressure water body pressure mistake
When big, elastic deformation occurs for brute spring 6, and then high-pressure water body is contacted with main valve plate 4, then stops high pressure water by main valve plate 4
Body, when main valve plate 4 for a long time by the impact failure of high-pressure hydraulic or fracture when, at this time can be after by another piece of auxiliary valve plate 7
Continuous blocking high-pressure water body, can then prevent butterfly valve from leaking, and leakproofness when butterfly valve is closed be improved, simultaneously because main valve
The inside of plate 4 and the inside of two pieces of auxiliary valve plates 7 are fixed with several reinforcing ribs 8, can reinforce main valve plate by reinforcing rib 8
4 and auxiliary valve plate 7 intensity, avoid main valve plate 4 and auxiliary valve plate 7 from damaging or fracture, extend the service life of butterfly valve, rotating
When upper valve rod 2, since the middle part of valve body 1 is ball valve, while elastic deformation can occur for brute spring 6, then can be to prevent
Only two pieces of auxiliary valve plates 7 interfere the rotation of main valve plate 4.
