Abstract
The utility model provides a core adjustment type gate plate gate valve used on fluid pipelines, which is mainly composed of a valve body, a valve rod, a main gate plate, a subsidiary gate plate, and a core adjusting ball, wherein, the main gate plate and the subsidiary gate plate are connected with the valve rod through a T-shaped buckle; the core adjusting ball can be designed into the shape that both sides are of a ball shape or one side is of a ball shape; an inner chamber corresponding to the curved face of the core adjusting ball is arranged at both sides of a plate surface between the main gate plate and the subsidiary gate plate; the core adjusting ball is arranged in the inner chamber. Because the core adjusting ball is additionally provided, the utility model causes the main gate plate and the subsidiary gate plate to be well sealed with a sealing surface, and thereby, avoids the leakage phenomenon of the valve, and has the advantages of easy manufacturing, convenient operation, no damage of the sealing surface in use, and extension of the service life of the valve.
Description
The utility model relates to a kind of valve, particularly is suitable for the core-adjustable type flashboard gate valve that uses on the fluid pipe-line.Along with the fast development of oil, chemical industry, more and more higher to the requirement of valve mass, the especially interior leakage problem of the seepage of valve more and more causes the attention of valve manufacturing firm.Existing valve is owing to the deficiency of its structure, and easily there are error in the sealing surface of its body cavity and flashboard in course of working, thereby cause seepage, and this has not only wasted great amount of manpower and financial resources, and relates to people's life safety.In addition, valve body sealing surface easily is scratched and damages, and influences its working life.
The purpose of this utility model is to provide a kind of accent core flashboard gate valve of stopping seepage, increasing the service life, to overcome the deficiencies in the prior art part.
For achieving the above object, technical solution of the present utility model is: it mainly is made up of valve body, valve rod, major and minor flashboard and core-adjustable ball; Major and minor flashboard links to each other with valve rod by T shape button, is equipped with core-adjustable ball between major and minor flashboard.
Above-mentioned core-adjustable ball can be Ф shape, is provided with on the biside plate face between the major and minor flashboard and the corresponding inner chamber of core-adjustable ball curved surface, and core-adjustable ball places above-mentioned inner chamber.
It is spherical in shape that above-mentioned core-adjustable ball also can a side, is equipped with on the side plate face between the major and minor flashboard and the corresponding inner chamber of core-adjustable ball curved surface, and another lateral plates then is provided with and the corresponding rectangular inner cavity of core-adjustable ball, and core-adjustable ball places above-mentioned inner chamber.
The utility model makes major and minor flashboard and valve body sealing surface reach good sealing owing to set up core-adjustable ball, thereby has stopped the existing phenomenon of seepage of valve, and easy processing, does not cause sealing surface impaired during use, has prolonged the working life of valve.
Description of drawings:
Fig. 1 is the utility model embodiment's a structural representation.
Below in conjunction with accompanying drawing the utility model and embodiment are described in further detail:
The utility model mainly is made up of valve body 1, valve rod 5, major and minor flashboard 2,9 and core-adjustable ball 8; Major and minor flashboard 2,9 buckles 6 by the button of the T shape on it 4,7 with the inverted T-shaped of valve rod 5 ends and links to each other.Above-mentioned core-adjustable ball 8 is rectangular, and the one side is designed to the spherical crown shape; Then on the main gate-board 2 plate faces between the major and minor flashboard 2,9, be provided with and core-adjustable ball 8 corresponding rectangular inner cavity 3, be provided with and the corresponding curved surface cavity 10 of the spherical crown of core-adjustable ball 8 on the auxiliary gate-board 9 plate faces between the major and minor flashboard 2,9, core-adjustable ball 8 places above-mentioned inner chamber 3,10.
It is all spherical in shape that above-mentioned core-adjustable ball 8 also can be designed to both sides, and promptly Ф shape at this moment, then is equipped with on the plate face of major and minor flashboard 2,9 inboards and the corresponding inner chamber of core-adjustable ball 8 curved surfaces, and core-adjustable ball 8 places above-mentioned inner chamber.
When throttle down, firmly handling valve rod 5 makes it descending, the major and minor flashboard 2,9 and the core-adjustable ball 8 that link to each other with valve rod 5 are also descending thereupon, when major and minor flashboard 2,9 comes downwards to the sealing surface 11 of valve body 1, major and minor flashboard 2,9 stops descending, and core-adjustable ball 8 is owing to be subjected to the downward active force of valve rod 5, make major and minor flashboard 2,9 to the left and right the sealing surface 11 of the valve body 1 of both sides fit.Because the fine setting effect of core-adjustable ball 8, thereby the sealing surface 11 of major and minor flashboard 2,9 and valve body 1 reaches good sealing effect, stopped the leakage problems of valve.
During Open valve, firmly handle valve rod 5 and make it up, moment can make major and minor flashboard 2,9 break away from the sealing surface 11 of valve body 1, so it is impaired to be difficult for scratch, has prolonged the working life of valve; And, make the upper and lower cavity pressure of valve body 1 reach state of equilibrium, guarantee that unlatching moment is little, operate nimble.
