Abstract
The utility model discloses an ellipsoidal ball valve, which comprises a valve body provided with a through hole. The interior of the valve body is provided with an installation hole, wherein the through hole and the installation hole are mutually perpendicular. An ellipsoidal valve core is arranged in the valve body. The upper end of the ellipsoidal valve core is provided with a valve rod. A graphite sealing ring module is arranged between the valve rod and the valve body. The long edge of the ellipsoidal valve core is provided with a channel matched with the through hole. The channel is formed at the center of the long edge. The inner and outer walls of the channel of the ellipsoidal valve core are provided with protective layers. The ellipsoidal valve core is subjected to the Co-W alloy plating treatment, thus is better in wear resistance, overpressure resistance and scouring resistance. The combination part of the valve rod and the valve body is sealed by graphite material, so that the ellipsoidal ball valve is good in sealing performance, corrosion resistance and lubricating property. Meanwhile, even if the ellipsoidal ball valve is not in use for a long period of time, the phenomenon that the ellipsoidal ball valve is difficult to use due to corrosion is avoided. The ellipsoidal ball valve is simple in structure and convenient to use, and the use value thereof is maximized under the same resource condition.
Description
Technical field
The utility model belongs to the ball valve technical field, is specifically related to a kind of spheroid shape ball valve.
Background technique
ball valve is widely used in industries such as petroleum refining, long-distance transport pipes, chemical industry, papermaking, pharmacy, water conservancy, electric power, municipal administration, iron and steel, its main feature is effective throttling, the wire drawing phenomenon is minimized thereby reduce the soaking of valve and valve seat (punching) erosion, and simple in structure, good seal performance, fluid resistance are little, a kind of ellipsoid core ball valve is disclosed in CN 202812281 U, comprise the valve body that is provided with through hole, described valve body is provided with the spool mounting hole perpendicular with described through hole, be arranged on the elliposoidal spool of valve body inner spool mounting hole, described elliposoidal spool vertically is arranged in the spool mounting hole, the top of described elliposoidal spool is provided with valve rod, be provided with Returnning spring between described valve rod and elliposoidal spool, the long limit of described elliposoidal spool is provided with the passage adaptive with described through hole, described channel setting is in Chang Biande center lower side, be provided with sealed department between described elliposoidal spool and described valve body.Of the present utility model simple in structure, easy to use, and good airproof performance.Yet its pressure at the ellipsoid core is subject to when sealing medium is even, its underpart thin location has been subject to the pressure same with the top thicker part, cause discontinuity to make its easy damage, it mainly plays reset role to adopt Returnning spring, yet for its Main Function of ball valve, be to play the effect of closing voluntarily, but to could open with very large power when opening, thus needs a kind of simple in structure, compression resistance good, the spheroid shape ball valve of long service life.
The model utility content
The purpose of this utility model be to provide a kind of simple in structure, compression resistance good, the spheroid shape ball valve of long service life.
Realize that the technological scheme that the purpose of this utility model adopts is: a kind of spheroid shape ball valve; comprise valve body; on described valve body, through hole is set; arrange and the orthogonal mounting hole of through hole in described valve body; the ellipsoid spool is set in described valve body; described ellipsoid spool vertically is arranged in valve body; described ellipsoid spool upper end arranges valve rod; the carbon seal ring module is set between described valve rod and valve body; described ellipsoid spool arranges on long limit and is provided with the passage that through hole matches; with outer wall, protective layer is set in described channel setting Zai Changbian center, described ellipsoid valve core channel.
Described carbon seal ring module comprises two carbon seal rings and belleville spring, and described belleville spring is arranged between two carbon seal rings.
Described protective layer is electrodeposited coating, and described electrodeposited coating is the cobalt base alloy electrodeposited coating.
Described cobalt base alloy is cobalt tungsten alloy.
Place, described passway is set to arc transition.
The utility model originally spool redesign of ball-shaped is the spheroid shape spool, increased the area of contact on spheroid shape spool pair and through hole direction, make under the effect of pressure medium its sealing better; Can not cause sealing gasket to lose efficacy because of sealing gasket on ellipsoid valve core channel top edge direct friction in closing course, so the seal ring in the valve hole setting is not mild because the long limit of ellipsoid spool radian is mild and at the place, passway, be set to the arc transition channel edge, is unlikely to the sealing gasket that causes in long-term using process and loses efficacy; With outer wall, electro-cladding is set all in the ellipsoid valve core channel, material is cobalt tungsten alloy, and the difficulty while making processing ellipsoid spool reduces, and is adopting the cobalt tungsten alloy plating that wear-resisting, withstand voltage, the resistance to erosion ability of ellipsoid spool are strengthened; Adopt the double-layer graphite sealing to prevent gap in valve rod and valve body junction, not only good seal performance and also corrosion-resistant, greasy property good, even and do not use for a long time and can not cause using because of corrosion the phenomenon of difficulty; The utility model is simple in structure, easy and simple to handle, has brought into play to greatest extent its use value under equal resources supplIes.
