Abstract
The utility model discloses a central cavity micro gap ball valve which comprises a valve body, a ball body, a valve cover, a valve seat and a valve rod. A hole identical with a channel of the valve body in size is formed in the ball body, the center of the hole passes through the axis of the channel, the distance between a central cavity of the valve body and the outer surface of the ball body is 0.5mm, the valve cover is installed on the outer portion of the valve body, the inner end of the valve rod is connected with the ball body, the valve seat is installed at the end of the central cavity of the valve body close to a pipeline, a groove is formed in the upper portion of the ball body, and a steel ball and a spring are connected in the groove. The gap between the central cavity and the outer surface of the ball body is small, no effusion or residue is accumulated in the central cavity, the surface of the ball body is not damaged, the service life of the ball body is prolonged, and loss of liquid media in the pipeline is less. The steel ball and the spring are used for preventing static, protecting the equipment and preventing the liquid media from being affected.
Description
Technical field
The utility model relates to the ball valve technical field, specifically the very little ball valve of a kind of spheroid and middle cavity gap.
Background technique
The open-shut device that revolves of ball valve is spheroid, manhole or passage is arranged by its axis.Ball valve is mainly used to cut off or change the flow direction of medium in pipeline, it only need just can be closed tightly with revolving the operation that turn 90 degrees and very little moment of rotation.The ball valve optimum uses as switch or cut-off valve, and recent development has become to have the effect of throttling and control flow with ball valve design.
But, present valve body lumen is the cast form face of non-processing, gap between valve body and the spheroid is big, make the granular solids deposition that contains in ducted liquid medium and the medium remain in the valve body lumen easily and form hydrops and residue, easily spherome surface is caused scuffing, reduce the working life of spheroid; And the loss of liquid medium in flowing is also big in the pipeline.
The model utility content
For solving the problems of the technologies described above, the utility model provides a kind of lumen microgap ball valve, its objective is the gap that reduces between valve body lumen and the outer surface of spheroid, makes to be difficult for forming hydrops and residue in the lumen.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of lumen microgap ball valve, comprise valve body, spheroid, valve gap, valve seat and valve rod, described valve gap is installed in the outside of described valve body, the inner of described valve rod connects described spheroid, described spheroid has a hole identical with the channel sized of described valve body, and the described hole center is on the axis of described passage, and described valve seat is installed in the nearly pipeline end of described valve body lumen, described lumen is shaped as sphere, and concentric with described spheroid.
Preferably, the distance between described outer surface of spheroid and the described lumen is 0.5mm.
Preferably, a groove is arranged at described spheroid top, and described groove one end is equiped with spring, and is provided with a steel ball between described spring and the described spheroid.
Preferably, the quantity of described valve seat is four.
By above technological scheme, a kind of lumen described in the utility model microgap ball valve has reduced the gap between valve body lumen and the outer surface of spheroid, makes that the impurity of larger particles is difficult to enter into lumen in the liquid medium, effectively reduce the scuffing to spherome surface, improved the working life of spheroid; After reduce in gap between middle cavity wall and the spheroid, just be difficult for residual liquid and residue in the lumen; And reduce the loss of liquid medium in flowing.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below.

Figure.
The represented corresponding part title of numeral among the figure:
1. valve body 2. valve gaps 3. spheroids 4. lumens 5. valve seats
6. valve rod 7. springs 8. steel balls
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model provides a kind of lumen microgap ball valve, and its principle is the distance that reduces between valve body lumen and the outer surface of spheroid, makes to be difficult for residual liquid and residue in the lumen.
Embodiment:
As shown in Figure 1, embodiment provides a kind of lumen microgap ball valve, and valve gap 2 is installed in the outside of valve body 1; Spheroid 3 has a hole identical with the channel sized of valve body 1, and the center of hole is on the axis of passage; Lumen 4 in the valve body 1 and the distance between spheroid 3 outer surfaces are 0.5mm, and four valve seats 5 are installed in four nearly pipeline ends of lumen respectively; One groove is arranged at spheroid 3 tops, and groove one end is equiped with spring 7, and between spring 7 and the spheroid 3 steel ball 8 is arranged; The inner of valve rod 6 connects spheroid 3.
A kind of lumen of the present utility model microgap ball valve, compared with ordinary ball valve, its lumen 4 is processing cast form faces, lumen 4 be shaped as sphere, and concentric with spheroid 3; Distance between spheroid 3 outer surfaces and the lumen 4 is 0.5mm, the impurity of the larger particles in the liquid medium can not remain in the lumen 4 like this, be difficult for residual liquid and residue in the lumen 4, like this can be to spheroid 3 surface tears, the loss of liquid medium in flowing also is micro-in the pipeline.Spring 7 and the steel ball 8 installed in the groove of spheroid 3 tops are used for preventing static, to reduce static to the harmful effect of equipment and liquid medium generation.
To disclosed a kind of lumen microgap ball valve embodiment's above-mentioned explanation, make related domain professional and technical personnel can realize or use the utility model.Multiple modification to these embodiments will be apparent concerning those skilled in the art, and defined General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments herein.Therefore, the utility model will can not be restricted to these embodiments shown in this article, but will meet the wideest scope consistent with principle disclosed herein and features of novelty.
