Abstract
The utility model provides a ball valve which comprises a valve body, a ball body, a valve cover, a valve rod and a valve seat, wherein the ball body is connected to the lower end of the valve rod; the valve seat and the ball body are arranged in the valve body; the ball body and the valve seat are both in integrally formed structures; and the valve cover is fixed above the valve body by bolts. Because the ball body and the valve seat are in the integrally formed structures, the combined structure is of a top mounted type and the valve cover and the valve body are connected by the bolts, the valve cover can be directly dismounted from a pipeline after a seal is worn out, and then the ball body and the valve seat are directly taken out to be replace with a new valve seat and a new ball body. Therefore, the ball valve is convenient to disassemble, maintain and replace, and a great quantity of material cost, manpower cost and time cost can be reduced.
Description
Technical field
The utility model relates to a kind of valve, relates in particular to the ball valve that a kind of valve seat and spheroid are the global formation structure.
Background technique
Ball valve is a kind of valve with extensive use field; When in band granular operating mode medium, using; Spherome surface and valve base surface all the time with the media particle friction; At present ball valve sealing face major part all be with cemented carbide to cemented carbide (metal to metal), Rockwell hardness can't satisfy the operating mode that becomes increasingly complex about 40 degree.Hardness can not avoid again inadequately with medium to rubbing, in the course of time, thereby sealing surface can friction damage lose sealing effect.On pipeline, directly disassemble valve, not only time-consuming but also consume manpower, the cost of changing whole valve is very high again, is welded direct to the valve on the pipeline for some especially, can only cut down valve is whole during dismounting, loses time especially, increases cost.
Summary of the invention
The purpose of the utility model is to provide a kind of ball valve, to solve that valve that existing ball valve sealing surface hardness causes is inadequately changed and the problem of demolition and maintenance valve difficulty on pipeline.
To achieve these goals; The ball valve that the utility model provides comprises valve body, spheroid, valve gap, valve rod, valve seat; Said spheroid is connected in the lower end of said valve rod, and said valve seat and spheroid are located in the said valve body, wherein; Said spheroid and valve seat are the global formation structure, and said valve gap passes through bolt in said valve body top.
According to a kind of preferred implementation of above-mentioned ball valve, wherein, said valve seat and spheroid are respectively the valve seat and the spheroid of zirconium oxide material.
Through spheroid and valve seat are adopted the global formation structure, structurally adopt upper-mounting type ball valve, valve gap adopts bolt to be connected with valve body; After sealing wear, the valve gap of can directly on pipeline, dismantling directly takes out spheroid, valve seat; The valve seat that more renews, spheroid; Whereby, the utlity model has demolition, repair, replacement advantage easily, and can practice thrift a large amount of Material Costs, human cost and time cost.
Description of drawings
Fig. 1 is the sectional structure schematic representation of the utility model preferred embodiment.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is explained further details.
Fig. 1 shows the schematic structure of the utility model preferred embodiment; Shown in it, this preferred embodiment comprises connecting base 2, gland 3, bolt 4, valve gap 5, O type circle 6, valve rod 7, fire-resistant packing ring 8, spring 9, spheroid 10, valve body 11, valve seat 12, O type circle 13, lower valve rod 14 and the blowdown valve 15 of handle 1, handle installation 1.Valve rod 7 upper ends are connected in connecting base 2, and the lower end is connected in spheroid 10.Form a cavity in the valve body 11, spheroid 10 is arranged in this cavity with valve seat 12.For the ease of demolition and maintenance; The spheroid 10 and the valve seat 12 of this preferred embodiment are the global formation structure; Valve gap 5 is fixed in valve body 11 tops through bolt 4, also is the top of aforementioned cavity, is provided with a plurality of sealing configurations between valve gap 5 and the valve body 11; O type circle 6 for example is to strengthen the sealing effect of aforementioned cavity.
In order to increase wear resistance, the valve seat 12 and the spheroid 10 of this preferred embodiment are the zirconium oxide material.
This preferred embodiment adopts the zirconium oxide global formation with spheroid 10 and valve seat 12; Its hardness reaches more than 70 degree, structurally adopts and goes up dress formula structure, and valve gap 5 adopts bolt 4 to be connected with valve body 11; After sealing wear; The valve gap 5 of can directly on pipeline, dismantling takes out the valve seat that more renews, spheroid with spheroid 10, valve seat 12.Operation is very simple and convenient, can practice thrift human and material resources greatly.
To sum up, spheroid of the utility model and valve seat directly adopt the zirconium oxide global formation, structurally adopt and adorn dismantled and assembled bolt arrangement.Through the change of sealing surface material, and the improvement of structure, the utility model not only can effectively increase the service life, and on pipeline, can directly change valve seat, spheroid, and cost saving improves operating efficiency.
Can know that by technological general knowledge the utility model can be realized through other the embodiment that does not break away from its spirit or essential feature.Therefore, above-mentioned disclosed embodiment with regard to each side, all just illustrates, and is not only.All in the utility model scope or the change that is being equal in the scope of the utility model all comprised by the utility model.
Claims (2)
