Abstract
The utility model discloses a butterfly valve, including the valve body, and set up in the inboard butterfly plate of valve body, reach the valve shaft that cooperates the installation with the butterfly plate, through -hole and lower through -hole have been seted up respectively to valve body upper portion and lower part, it is provided with wear -resisting cover respectively with lower through -hole inboard to go up the through -hole, wear -resisting cover inboard is provided with wear -resisting sealing ring, the wear -resisting cover outside is provided with the bearing, the valve shaft passes the diaxon respectively and holds, the butterfly plate reaches the ceramic layer constitution of cladding in the inner panel outside by the inner panel. The utility model discloses a butterfly valve leads through the bearing, protects through wear -resisting cover, can protect the valve body, can seal up well under the circumstances that reduces wearing and tearing through the inboard wear -resisting sealing ring of wear -resisting cover, and the butterfly plate can stablize the water conservancy diversion when opening and shutting, guarantees its leakproofness when closing.
Description
Technical field
The utility model relates to a kind of valve, is specifically related to a kind of butterfly valve, belongs to valve technology field.
Background technique
Butterfly valve is Flap valve again, it is the simple modulating valve of a kind of structure, the butterfly valve that can be used for the switch control rule of low pressure pipeline medium refers to that closure member (flap or butterfly plate) is disk, rotate a kind of valve reaching open and close around valve shaft, valve can be used for the flowing controlling all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.On pipeline, main rising is cut off and throttling action; Butterfly valve open-shut device is a discoidal butterfly plate, rotates in valve body around the axis of himself, thus reaches the object opening and closing or regulate; Butterfly valve standard-sized sheet is normally less than 90 ° to complete shut-down, and butterfly valve and butterfly bar itself do not have self-lock ability, in order to the location of butterfly plate, will install worm speed reducer additional on valve rod; Adopt worm speed reducer, butterfly plate not only can be made to have self-lock ability, make butterfly plate stop on arbitrary position, the operating characteristics of valve can also be improved; The feature of the special butterfly valve of industry can be high temperature resistant, and applicable pressure range is also higher, and valve inside nominal diameter is large, and valve body adopts carbon steel manufacture, and the seal ring of valve plate adopts metal ring to replace rubber ring.Large high-temperature butterfly valve adopts Plate Welding manufacture, is mainly used in cigarette air channel and the gas pipe line of high temperature media.In existing butterfly valve using process, due to self-locking and the location of worm speed reducer, larger to valve body wearing and tearing, and after its use a period of time, inner seal is poor.
Model utility content
(1) technical problem that will solve
For solving the problem, the utility model proposes a kind of butterfly valve, valve body wearing and tearing can be reduced, and improve its overall tightness.
(2) technological scheme
Butterfly valve of the present utility model, comprises valve body, and is arranged at the butterfly plate inside valve body, and coordinates the valve shaft installed with butterfly plate, and described valve body upper and lower offers through hole and lower through-hole respectively; Wear-resistant sleeve is respectively arranged with inside described upper through hole and lower through-hole; Wear-resistant seal ring is provided with inside described wear-resistant sleeve; Described wear-resistant sleeve arranged outside has bearing; Described valve shaft is each passed through two bearings; Described butterfly plate is by inner panel, and the ceramic layer be coated on outside inner panel is formed.
As preferred embodiment, in the middle part of described ceramic layer outer shroud, offer an annular groove; A sealing O type circle is provided with in described annular groove.
Further, described surface ceramii layer is provided with many water conservancy diversion lines.
Further, described wear-resistant seal ring is made up of metal ring and O type rubber ring.
(3) beneficial effect

Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Embodiment
A kind of butterfly valve as shown in Figure 1, comprises valve body 1, and is arranged at the butterfly plate 2 inside valve body, and coordinates the valve shaft 3 installed with butterfly plate, and described valve body 1 upper and lower offers through hole 4 and lower through-hole 5 respectively; Wear-resistant sleeve 6 is respectively arranged with inside described upper through hole 4 and lower through-hole 5; Wear-resistant seal ring 7 is provided with inside described wear-resistant sleeve 6; Described wear-resistant sleeve 6 arranged outside has bearing 8; Described valve shaft 3 is each passed through two bearings 8; Described butterfly plate 2 is by inner panel (not shown), and the ceramic layer 9 be coated on outside inner panel is formed.
An annular groove is offered in the middle part of described ceramic layer 9 outer shroud; A sealing O type circle 11 is provided with in described annular groove.
Described ceramic layer 9 surface is provided with many water conservancy diversion lines 12.
Described wear-resistant seal ring 7 is made up of metal ring and O type rubber ring.
Butterfly valve of the present utility model; led by bearing; protected by wear-resistant sleeve; can protect valve body; can when reducing wearing and tearing by the wear-resistant seal ring inside wear-resistant sleeve; seal well, and butterfly plate can carrying out stable water conservancy diversion when folding, ensureing its sealing when closing.
Embodiment recited above is described preferred implementation of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from the utility model design concept; the various modification that related domain ordinary person makes the technical solution of the utility model and improvement; protection domain of the present utility model all should be dropped into; the technology contents of the utility model request protection, all records in detail in the claims.
