Abstract
The utility model provides a breach type antiscour spheroid, is including being equipped with the spherical body of latus rectum, open in the end edge of latus rectum department jagged, this breach be located with disk seat switching complex body lateral wall. The utility model discloses a rational in infrastructure, valve open with close instantaneous, the breach makes the medium of spheroid latus rectum mouth pass through the area fold increase, has obviously reduced the velocity of flow that the medium passes through, even the medium is the operating mode that contains granule, heavy pressure, also can significantly reduce to the abrasion of spheroid and disk seat, avoids the valve to damage at the excessive speed. And the breach makes spheroid latus rectum mouth have abundant truncated edge edge, is difficult to appear the coating line and splits.
Description
Technical field: the utility model relates to a kind of ball valve, particularly ball valve core.
Background technique: ball valve is instantaneous what open and close, the medium of spheroid latus rectum mouth is very little by area, makes the flow velocity of medium very high, if medium is the operating mode containing particle, high pressure, very large to the erosive wear of spheroid and valve seat instantaneously, is easy to damage valve.Further, because spheroid generally has surface coated treatment, the sharp edge edge of the spheroid latus rectum mouth also easy painting laminated striation that makes in washing away splits.
Summary of the invention: for the deficiencies in the prior art, the utility model provides a kind of breach type antiscour spheroid rational in infrastructure.
The utility model comprises the ball being provided with latus rectum, has breach at the end edge place of latus rectum, and this breach is positioned at on the body sidewall of valve seat opening and closing cooperation.
Of the present utility model rational in infrastructure, instantaneous in valve opening and closedown, breach makes the medium of spheroid latus rectum mouth be multiplied by area, significantly reduce the flow velocity that medium passes through, even if medium is the operating mode containing particle, high pressure, also can greatly reduce the erosive wear to spheroid and valve seat, avoid the too fast damage of valve.Further, breach makes spheroid latus rectum mouthpiece have abundant root face edge, is not easy to occur that being coated with laminated striation splits.
The utility model is further illustrated below in conjunction with drawings and Examples.
Accompanying drawing illustrates: Fig. 1 is the main structure schematic diagram of embodiment.
Fig. 2 is the schematic appearance of embodiment.
Embodiment: as depicted in figs. 1 and 2, is provided with latus rectum 2 in spherical body 1, has breach 3 at the end edge place of latus rectum 2, and this breach 3 is positioned at on body 1 sidewall of valve seat opening and closing cooperation.The shape of breach 3 according to circumstances can have multiple design, and the profile line shape complications of the breach 3 of the present embodiment are in " W " shape.
Actual use, spherical body 1 rotates and valve seat coordinates, instantaneous in valve opening and closedown, and breach 3 makes the medium of latus rectum 2 oral area be multiplied by area, obviously can reduce the flow velocity that medium passes through, minimizing erosive wear.
