Abstract
The utility model relates to an adjustable flowing ball valve core, comprising a circular valve core body made of ceramic material; wherein, a valve rod interface is arranged on the top end of the valve core body; a medium through hole is arranged on the middle of the valve core body, a side interface of which is abnormity; the abnormity port is formed by the combination of a semi-circle port and a V-shaped port. The utility model overcomes the shortcomings of low adjustment precision, weak wear and corrosion resistant capability in the common ball valve core of the prior art, and utilizes the combination design of the semi-circle port and the V-shaped port, so the highly precisely controlling adjustment on the medium flowing during the valve core is turned to be opened or closed is achieved; the utilization of the ceramic material further improves the wear and corrosion resistance performance. The valve core has the advantages of simple structure, highly adjusted precision, easy operation, wide application, long service life and strong reliability.
Description
Affiliated technical field
The utility model relates to a kind of ball valve spool of can regulate flow.
Background technique
Traditional ball valve spool all is circular and made by metallic material, and the top of valve core is the valve rod interface, and the middle part of valve core is a medium through hole, and two side interfaces of medium through hole generally all be circle.Though this ball valve also can reach certain Flow-rate adjustment with spool when rotating, but its precision is low, the occasion that is not suitable for having at some higher adjusting requirement is used, and wear-resisting, the decay resistance of traditional metallic spool a little less than, also be not suitable for controlling the transmission of some special pearl media.
Summary of the invention
Low in order to overcome ordinary ball valve in the prior art with the degree of regulation of spool, the problem wear-resisting, that decay resistance is more weak, the utility model provides a kind of ball valve spool of can regulate flow, the ball valve of this can regulate flow with spool simple in structure, degree of regulation is high, easy to operate, applied widely, long service life, good reliability.
The technological scheme that its technical problem that solves the utility model adopts is: comprise circular valve core, the top of valve core is the valve rod interface, the middle part of valve core is a medium through hole, and a side interface of medium through hole is an abnormity, and this heterointerface is engaged by semicircular opening and " V " shape mouth and constitutes.
Valve core is made by stupalith.
The utility model is by the bond layout of above-mentioned semicircular opening and " V " shape mouth, make spool when rotarily opening or close, can carry out high-precision regulating and controlling to rate-of flow, the use of its ceramic material has further improved wear-resisting, the decay resistance of spool again, have simple in structure, degree of regulation is high, the advantage of easy to use, applied widely, long service life, good reliability.
Description of drawings
Below in conjunction with drawings and Examples detailed content of the present utility model is described.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the right elevation of Fig. 1.
Embodiment
As shown in the figure, the utility model comprises circular valve core 1, valve core 1 is made by stupalith, as zirconium oxide, aluminium oxide, Zirconia reinforced alumina etc., the top of valve core 1 is a valve rod interface 2, by valve rod interface 2, valve core 1 links to each other with valve rod, and drive valve core 1 by valve rod and rotarily open or close, the middle part of valve core 1 is a medium through hole 3, a side interface of medium through hole 3 be special-shaped, this heterointerface is engaged by semicircular opening 4 and " V " shape mouth 5 and constitutes, the combined shaped of semicircular opening 4 and " V " shape mouth 5, the MEDIA FLOW port area when making valve core 1 rotarily open or close and between valve body constantly increases or reduces, thereby reaches the purpose of regulating and controlling flow.
Claims (2)
1, a kind of ball valve spool of can regulate flow, comprise circular valve core, the top of valve core is the valve rod interface, and the middle part of valve core is a medium through hole, a side interface that it is characterized in that medium through hole (3) is abnormity, and this heterointerface is engaged by semicircular opening (4) and " V " shape mouth (5) and constitutes.
2, the ball valve spool of can regulate flow according to claim 1 is characterized in that valve core (1) made by stupalith.
