Description
Technical field
The utility model is related to a kind of ball valves, and in particular to a kind of ceramic ball valve.
Background technology
Metal valve has not adapted to high abrasion, strong corruption in the adverse circumstances industries such as many industry chemical industry, coal
The demand of the bad working environments such as erosion is mainly reflected in situations such as metal valve is easily revealed, torque is big, sealing surface is not corrosion-resistant, and ceramic
Material is constantly extended because of performances such as its higher strengths in tension and compression, elasticity modulus, hardness in the application range of industrial valve,
It especially faces severe use environment, the ceramic valves such as high abrasion, deep-etching, high temperature, high pressure and more shows superior performance, therefore
The seal member of valve is made using the wearability of ceramics, rotproofness and easily worn part replaces metal material, already becomes industry
Inside important development direction in recent years.
At present ceramic valve when in use between it is long after, abrasion is will produce between valve seat and sphere, gap may be will produce,
The material of conveying, which is possible to enter in gap, is deposited in spool position, causes very big resistance to the rotation of spool, be easy to cause
Stuck valve brings great insecurity, base if switch is possible to that valve body cracking can be caused even to burst by force to production
It is proposed that the ball valve equipped with filler avoids above-mentioned safety problem in a kind of in this application.
Utility model content
The purpose of this utility model is to provide a kind of interior ceramic ball valves for setting filler.
To achieve the above object, the utility model uses following technical scheme：
Set the ceramic ball valve of filler in a kind of, including the valve deck of the valve body of metal, metal, ceramic valve seat, spheres of ceramic,
Body and valve rod in ceramics, the valve deck are connected to the both ends of valve body by fastener, and the inner surface of the valve body is equipped with middle body, institute
It states ceramic valve seat and is divided into left ceramic valve seat and right ceramic valve seat, the left ceramic valve seat and right ceramic valve seat are close to both ends respectively
Valve deck extend at middle body, spheres of ceramic between left ceramic valve seat and right ceramics seat, the middle body, ceramic valve seat and
It is provided with filler in the space that spheres of ceramic is constituted.
The both sides of the upper and lower end face of the spheres of ceramic offset with ceramic valve seat respectively, and ceramic valve seat is resisted against spheres of ceramic
One side be the cambered surface to fit with spheres of ceramic surface, the extrados of the ceramic valve ball and the cambered surface kissing of ceramic valve seat
It closes, covers all the entire cambered surface of ceramic valve seat.
The filler is ceramic member, polytetrafluoroethylene (PTFE) or organic filler.
The shaft lower end of the valve rod circumferentially forms step.
After adopting the above technical scheme, the utility model compared with the background art, has the following advantages that：
1, the edge of spheres of ceramic through-hole of the utility model matches with the cambered surface edge of valve seat, avoids the object of conveying
Expect the bulk deposition in edge, only has minimal residue, material to be not easily accessible in the gap in valve chamber in valve chamber, and because chamber
Internal gap is small, and either crystallization or fragment are not easily accessed in gap, it is not easy to be freezed valve, will not be caused valve
Ball is stuck.
2, it is mutually fitted close between valve rod, middle body, ceramic valve seat and filler so that the bottom periphery of valve rod is not left a blank
Gap will not infilter medium in this way, avoid causing residual of the conveying material in valve chamber.
Description of the drawings
Fig. 1 is the schematic cross-section of the utility model；
Fig. 2 is the schematic cross-section of the utility model another embodiment.
Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
Embodiment one
Refering to Figure 1, the utility model discloses a kind of interior ceramic ball valves for setting filler comprising metal material
Valve body 1, the valve deck 2 of metal material, ceramic valve seat 3, body 6 in spheres of ceramic 4 and valve rod 5 and ceramics.
Wherein valve deck 2 is connected to the both ends of valve body 1 by fastener, and fastener is bolt etc., and ceramic valve is equipped in valve deck 2
Seat 3, the both sides of the Inner Constitution runner of ceramic valve seat 3, the upper and lower end face of spheres of ceramic 4 offset with ceramic valve seat 3 respectively, ceramics
The one side that valve seat 3 is resisted against spheres of ceramic 4 is the cambered surface to fit with spherome surface.The extrados and ceramic valve of ceramic valve ball 4
The cambered surface of seat 3 matches, and covers all the entire cambered surface of ceramic valve seat 3, and for such ceramic valve ball closer to spherical shape, sphere is logical
Gap is small between edge at hole and the edge of valve seat cambered surface, avoids bulk deposition of the material of conveying in gap, valve chamber
Interior only minimal residue.
The upper end of spheres of ceramic 4 connects valve rod 5, and the inner surface of valve body 1 is equipped with middle body 6, and ceramic valve seat 3 divides for left ceramic valve
The valve deck 2 that seat and right ceramic valve seat, left ceramic valve seat and right ceramic valve seat are close to both ends respectively extends at middle body 6, ceramics
Sphere 4 is between left ceramic valve seat and right ceramics seat, in the sky that middle body 6, the ceramic valve seat 3 of left and right and spheres of ceramic 4 are constituted
Interior to be provided with filler, filler is ceramic member 9.
Embodiment two
Fig. 2 show another embodiment schematic diagram of the utility model, the difference between this embodiment and the first embodiment lies in
Filler is different, and the material of filler 10 is polytetrafluoroethylene (PTFE) (PTFE), or can also select organic filler, polytetrafluoroethyl-ne
Alkene (PTFE) or organic filler have elasticity, when generated between valve ball and valve seat form gap when, can opposite joint radially
Gap compensates, and conveying material is avoided to pass through from gap, to ensure leakproofness, while also ensureing the anti-jamming effect of valve
Fruit improves security performance.
The shaft lower end of valve rod 5 circumferentially forms step, so that valve rod 5 is coordinated with periphery closer, can prevent valve rod 5 from flying
Go out, is equipped with packing seal component along the periphery of valve rod 5, packing seal component includes the pressing plate 81 from top to bottom set gradually, fills out
Material pressing sleeve 82 and filler group 83, filler group 83 are located between the lower part and valve body 1 of valve rod 5.
The sealing performance of ball valve can be improved in the setting of filler assembly, especially for the guarantee for providing sealing at valve rod 5, meets
The requirement of low leakage rate adapts to the job requirement of hot environment.
The preferable specific implementation mode of the above, only the utility model, but the scope of protection of the utility model is not
It is confined to this, any one skilled in the art within the technical scope disclosed by the utility model, can readily occur in
Change or replacement, should be covered within the scope of the utility model.Therefore, the scope of protection of the utility model should
It is subject to the protection scope in claims.
