Abstract
The utility model discloses a novel connecting ball valve which comprises a valve body and a valve rod arranged on the valve body. A sealing ring is arranged between the valve rod and the valve body and buckled in a clamping groove of the valve rod. The novel connecting ball valve is simple and exquisite in structure, not prone to cracking, and capable of greatly prolonging service life of products and the sealing ring.
Description
Technical field
The utility model relates to a kind of novel conjoined ball valve.
Background technique
At present, China has been maximum in the world structural material producing country and country of consumption.Main building material product cement, sheet glass, construction sanitary ceramic, stone material and materials for wall Isoquant rank first in the world for many years.Simultaneously, the building material product quality improves constantly, and the energy and raw materials consumption descend year by year, and various building materials continue to bring out, and building material product constantly upgrades.
On existing ball valve, there are many deficiencies, between complex structure, especially valve body and the valve rod, under normal the use, the life-span and the phenomenon of splitting easily occurs generally between 1-2, causes seepage, and impact is normally used.
As from the foregoing, the problem that exists in the present product is badly in need of solving.
In view of this, the inventor has done deep research to this, and by feat of the experience of being engaged in for many years relevant industries and practice, design a kind of novel conjoined ball valve, can solve above-mentioned the deficiencies in the prior art part, exquisiteness simple in structure is not easy to occur the phenomenon of splitting, greatly prolong simultaneously the working life of product and seal ring, this case produces thus.
Summary of the invention
The purpose of this utility model is to provide a kind of novel conjoined ball valve, can solve above-mentioned the deficiencies in the prior art part, and exquisiteness simple in structure is not easy to occur the phenomenon of splitting, and greatly prolongs the working life of product and seal ring simultaneously.
To achieve these goals, the technical solution of the utility model is as follows:
Novel conjoined ball valve comprises valve body and is arranged on valve rod on the valve body, it is characterized in that: be provided with seal ring between valve rod and valve body, described seal ring is buckled in the draw-in groove on the valve rod.
The setting of this structure has improved usability and working life, and seal ring is buckled in the draw-in groove on the valve rod, good sealing effect, and under normal the use, the life-span nor easily occurs splitting probably in 5-10, greatly prolongs the working life of product.
Further, described seal ring is made with ternary one product glue material.
Further, the cross section of described seal ring is oval, and the length of major axis is D, and the length of minor axis is d, and the degree of depth of draw-in groove is h, wherein, 1.5≤D:h≤2,1≤d:h≤1.2, this D:h the best is 1.5, this d:h the best is 1.2.
The utility model is studied the ratio between seal ring and the draw-in groove, and adjust, compared with prior art, the seal ring tightness of this product is high, and the degree of adaptability between seal ring and the draw-in groove is good, and seal ring in use, suffered pressure so that seal ring extremely cooperate closely with draw-in groove, form interference fit, also form and cooperates closely simultaneously with between the valve body, greatly improve sealing.
If seal ring is too small, often can form sealing in the early stage, but service time one is of a specified duration, the gap will appear, cause seepage, to have under one's command also and can accelerate by the seal ring aging speed, working life is not long, and this client makes troubles.
The beneficial effects of the utility model: the utility model exquisiteness simple in structure, be not easy to occur the phenomenon of splitting, greatly prolong the working life of product and seal ring simultaneously.
In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Embodiment
As shown in Figure 1, the utility model relates to a kind of novel conjoined ball valve, comprises valve body 1 and is arranged on valve rod 2 on the valve body 1, it is characterized in that: be provided with seal ring 3 between valve rod 2 and valve body 1, described seal ring 3 is buckled in the draw-in groove 4 on the valve rod 2.
Further arrange, described seal ring 3 usefulness ternarys one product glue material is made.
Further arrange, the cross section of described seal ring 3 is oval, and the length of major axis is D, and the length of minor axis is d, and the degree of depth of draw-in groove 4 is h, wherein, 1.5≤D:h≤2,1≤d:h≤1.2, this D:h the best is 1.5, this d:h the best is 1.2.
As from the foregoing, the utility model exquisiteness simple in structure is not easy to occur the phenomenon of splitting, and greatly prolongs the working life of product and seal ring simultaneously.
The above only is an embodiment of the present utility model, is not the restriction to this case design, and all equivalent variations of doing according to the design key of this case all fall into the protection domain of this case.
