Abstract
The utility model discloses an eccentric half ball valve, including valve body and hemisphere case, the both sides of valve body are equipped with influent stream mouth, play stream outlet respectively, install hemisphere case through last semi-axis and lower semi-axis rotation in the valve body respectively, the last semi-axis is the step shaft, the both ends of step shaft are first polished rod axle, second polished rod axle, it has several beads to distribute on the connecting axle between first polished rod axle and the second polished rod axle, be equipped with the recess that several and bead mutually supported in the upper shaft cover of hemisphere case, sealed cooperation between last semi-axis and the valve body, the surface of hemisphere case is scribbled and is scribbled the corrosion resistant layer. The utility model discloses simple structure, installation convenient to use, through the special connection structure of valve body and hemisphere case, its stability is good, is difficult to not hard up, has guaranteed the long-time normal work of valve, and corrosion resisting property is good, long service life.
Description
Technical field
The utility model relates generally to pipeline control valve door field, relates in particular to a kind of eccentric half-ball valve.
Background technique
It is a lot of in pipeline, to work the ball valve kind of blocking medium, and hard seal eccentric ball valve and soft seal eccentric half-ball valve are arranged, and the sealing of hard seal eccentric semi ball valve is a metal to metal; The mutual friction of phase-contact surface meeting phase makes to be sealed with certain leakage after long-time the use, and the sealing of soft seal eccentric half-ball valve is a metal pair rubber; The long-time back phase-contact surface that uses can the phase mutual friction, and sealing can reach zero leakage, between existing in the market its valve body of eccentric half-ball valve and the hemisphere spool through spool being connected with independent fixed by nut; After long-time the use, nut is loosening easily, influences the proper functioning of valve; The hemisphere spool adopts general material to process; Be in for a long time in the working fluid, corroded easily, working life is short.
The model utility content
The purpose of the utility model is in order to remedy the deficiency of prior art, a kind of eccentric half-ball valve to be provided, and has solved to be connected with independent fixed by nut through axle between valve body and the hemisphere spool; After long-time the use, nut is loosening easily, influences the proper functioning of valve; The hemisphere spool adopts general material to process; Be in for a long time in the working fluid, corroded easily, problem such as working life is short.
The utility model is realized through following technological scheme:
A kind of eccentric half-ball valve; Include valve body and hemisphere spool, the both sides of said valve body are respectively equipped with inflow port, go out head piece, are rotatablely equipped with the hemisphere spool through last semiaxis and following semiaxis respectively in the said valve body; Said upward semiaxis is a multidiameter shaft; The two ends of said multidiameter shaft are the first polished rod axle, the second polished rod axle, are distributed with several fins on the coupling shaft between the said first polished rod axle and the second polished rod axle, are provided with the groove that several and fin cooperatively interact in the Upper shaft sleeve of said hemisphere spool; Said going up between semiaxis and the valve body is sealed and matched, and the outer surface of said hemisphere spool is coated with anti-corrosion layer.
Described eccentric half-ball valve is characterized in that: the diameter of the described first polished rod axle is greater than the diameter of coupling shaft, and the diameter of the said second polished rod axle is less than the diameter of coupling shaft.
The working principle of the utility model is to make valve unimpeded or inaccessible by rotary spool; Simultaneously between upper and lower semiaxis and the bearing support and adopt soft sealing structure respectively between hemisphere spool and valve flowing channel one side; Make that the ball valve switch is light; Sealing is reliable, and sealing surface and the sphere closed state of being everlasting is difficult by the medium erosion; And the connection between its each parts is simple, sealing, firm, can not use the unlatching freely of breaking down or having influence on valve because of the generation of scale formation because of long-term.
Cooperatively interact through the fin of last semiaxis and the groove of Upper shaft sleeve simultaneously; Avoided adopting independent fixed by nut loosening easily, influenced the proper functioning of valve, the structural design of the outer surface anti-corrosion layer through the hemisphere spool; Reduced working fluid spherical valve body corroded long service life.
The advantage of the utility model is following:
The utility model is simple in structure, easy to install, and through the special linkage structure of valve body and hemisphere spool, its good stability is not easy to become flexible, and has guaranteed the long proper functioning of valve, corrosion resistance and good, long service life.
