Description
Technical field
The utility model is related to a kind of ball valve, and specifically a kind of rubber sleeve wraps up the ball valve of spheroid.
Background technology
Ball valve (ball valve), standard GB/T21465-2008《Valve term》Defined in be：Opening and closing element (spheroid) by
Valve rod drives, and the valve rotated around ball valve axis.Also it can be used for the regulation and control of fluid, wherein hard valve V-type
There is very strong shearing force between its V-type core of ball valve and the metal seat valve of pile-up welding hard alloy, fibre-bearing is particularly suitable for use in, micro-
The medium of small solid particle etc..And multi-pass ball valve not only can flexibly control cutting for interflow, shunting and the flow direction of medium on pipeline
Change, while any passage also can be closed and two other passage is connected.This class valve should be typically horizontally mounted in the duct.
Ball valve is divided into according to type of drive：Pneumatic ball valve, electrical ball valve, manual ball valve.
Existing ball valve is all to rotate to realize closing between valve seat using valve, and then realizes valve, but this
Planting valve needs to rub between valve and valve seat, and the problem of so will result in serious wear, in order to solve the above problems, now carries
The ball valve of spheroid is wrapped up for a kind of rubber sleeve.
Utility model content
The purpose of this utility model is to provide the ball valve that a kind of rubber sleeve wraps up spheroid, to solve in above-mentioned background technology
The problem of proposition.
To achieve the above object, the utility model provides following technical scheme：
A kind of rubber sleeve is wrapped up to be coordinated in the valve cavity in the ball valve of spheroid, including valve body and ball body of valve, the valve body
Provided with ball body of valve, valve seat, ball body of valve upper end connection valve rod, ball body of valve and valve seat are provided with the valve body below ball body of valve
Valve face coated with hard alloy, valve body, the passage also coated with hard alloy of spheroid can thus improve overall wear-resisting of ball valve
Performance, so as to be favorably improved the service behaviour and service life of device, valve seat is surrounded by rubber sleeve, rubber with ball body of valve
Gum cover makes two semicircles.
It is used as further program of the utility model：The valve rod upper end is placed through the bonnet of valve body upper end.
It is used as further program of the utility model：Sealing structure is provided between the bonnet and valve rod.
It is used as further program of the utility model：The valve rod upper end is provided with handle.
It is used as further program of the utility model：The ball body of valve can be rotated in rubber sleeve.
Compared with prior art, the beneficial effects of the utility model are：The utility model is simple and reasonable for structure, by
The valve face coated with hard alloy of ball body of valve and valve seat, valve body, the passage also coated with hard alloy of spheroid, can thus be improved
The overall anti-wear performance of ball valve, so that the service behaviour and service life of device are favorably improved, valve seat and ball body of valve outside
Rubber sleeve is wrapped in, rubber is cased with two effects, and one can ensure the sealing of valve seat lower curtate, secondly prevent rubber sleeve from coming off,
Because rubber sleeve is coated with spheroid, when spheroid is rotated, the particle in medium can be prevented to enter in valve body.Effectively prevent particle from existing
Valve pocket heap, ties and influences the sealing property of valve, and if here in the later stage in use, rubber sleeve is damaged, only need list
Rubber sleeve is solely changed, without being changed to ball valve hardware, the service life of device is greatly improved.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein：Include valve body 1, rubber sleeve 2, valve seat 3, ball body of valve 4, valve rod 5.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Referring to Fig. 1, in the utility model embodiment, a kind of rubber sleeve wraps up the ball valve of spheroid, including valve body 1 and valve
Coordinate in valve cavity in spheroid 4, the valve body 1 and be provided with ball body of valve 4, valve seat 3 is provided with the valve body 1 of the lower section of ball body of valve 4,
The upper end of ball body of valve 4 connects valve rod 5, and the upper end of valve rod 5 is placed through the bonnet of the upper end of valve body 1, and the upper end of valve rod 5 is provided with handle, valve
The valve face coated with hard alloy of sealing structure, ball body of valve and valve seat, valve body, the passage of spheroid are provided between lid and valve rod 5
Also coated with hard alloy, can thus improve the overall anti-wear performance of ball valve, thus be favorably improved device service behaviour and
Service life, valve seat 3 is surrounded by rubber sleeve 2 with ball body of valve 4, and ball body of valve 4 can be rotated in rubber sleeve 2, rubber
Set 2 makes two semicircles, and elasticity during assembling by rubber is squeezed into valve support chamber, and rubber sleeve 2 has two effects here, and one can
,, can be with when spheroid is rotated because rubber sleeve is coated with spheroid secondly prevent rubber sleeve from coming off to ensure the sealing of valve seat lower curtate
