Abstract
The utility model relates to the technology field of a quantitative regulator valve, in particular to a cone-arc-shaped valve core of a quantitative regulator valve. The utility model is characterized in that the bottom plane of the cone-shaped valve core is additionally provided with an arc-shaped bulge. Compared with the prior art, the utility model has the advantages that the bottom part of the cone-shaped valve core is designed into the arc-shaped bulge, so medium resistance is reduced in operation; the acting point of wearing is fallen on the arc-shaped bulge part, so the wearing to the flow regulating part of the cone-shaped valve core is reduced, and the service life of the valve core is prolonged.
Description
[technical field]
The utility model relates to quantitative modulating valve technical field, the quantitative regulation valve core of specifically a kind of awl arc.
[background technique]
The size of ducted fluid flow can be controlled by valve, and the key position of the adjusting flow section size of various valves is all different, these valves are in open degree from large to small the time, the shape of its flow-passing surface will change, when little open degree, flow section becomes a slit that width is very little.The taper valve core of general quantitative modulating valve, its conical lower portion are disk, and through the mill that dashes of long-time strong current, wear and tear easily in the corner of foundation ring, make its quantitatively deviation to some extent, and be accurate inadequately.
[summary of the invention]
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of spool that can reduce the quantitative modulating valve of resistance is provided.
In order to achieve the above object, the utility model proposes the quantitative regulation valve core of a kind of awl arc, it is characterized in that: arc-shaped convex is set up in the bottom plane at taper valve core.
The utility model is compared with prior art, with the bottom design of taper valve core projection in the arc-shaped, not only when operation, reduce resistance of medium, and the Point of Strength of wearing and tearing has dropped on the arc-shaped convex position, reduce the wearing and tearing of taper valve core being regulated the flow position, prolonged the working life of spool.
[description of drawings]
Fig. 1 is a structural representation of the present utility model.
Referring to Fig. 1,1 is valve rod; 2 is taper valve core, and its bottom is an arc-shaped convex.
[embodiment]
Below in conjunction with accompanying drawing the utility model is further described.
The taper valve core of quantitative modulating valve is done improvement, referring to Fig. 1, promptly set up arc-shaped convex in original quantitatively bottom of the taper valve core 2 of modulating valve, this arc-shaped convex, effectively dispersion medium pressure makes operation more smooth and easy, laborsaving, and has reduced the spool key position, be the taper valve core wearing and tearing of corner all around on plane bottom promptly original, thereby guaranteed the precision of quantitative modulating valve; Because spool is subjected to the relative minimizing of resistance, has also reduced the stressed of valve rod 1 and taper valve core 2 joints, thereby also prolonged the working life of valve rod and spool in addition.
