Abstract

The utility model discloses a single seat sleeve regulating valve comprising a valve body, a valve seat, a valve core, a valve rod, a valve cap, a sleeve and a filling component, wherein the valve core is H-shaped, both ends of the valve core adopt sealing surfaces, and the valve core and the valve rod adopt a detachable connecting structure. The service life of the valve core provided by the utility model is prolonged by two times correspondingly, and the cost of the valve is reduced as well.

Description

A kind of single seat sleeve adjusting valve
Technical field
The utility model relates to a kind of valve, is specifically related to a kind of single seat sleeve adjusting valve.
Background technique
The single seat sleeve adjusting valve is a kind of valve commonly used, is widely used in fields such as chemical industry, oil, metallurgy, power station and light textile at present.
Existing single seat sleeve adjusting valve mainly comprises valve body 1, valve seat 2, spool 3, valve rod 4, valve gap 5, sleeve 6 and filler assembly 7 referring to shown in the accompanying drawing 1~2, and sealing surface 8 is located at the spool bottom.Existing spool mostly is an inverted U-shaped, and generally adopts single sealing surface design.
Yet, because flowing medium is to the continuous erosion of sealing surface, particularly under bad working environments such as cavitation erosion, granule medium, sealing surface can be destroyed behind the operation certain hour, even the sealing surface weld deposit cemented carbide, also some time can only be prolonged a little, and after waiting sealing surface to destroy, must process or directly change spool again to spool, therefore, the working life of existing valve core structure is shorter, the also corresponding cost of production that improves the single seat sleeve adjusting valve.
Summary of the invention
The utility model purpose provides a kind of single seat sleeve adjusting valve, to improve the working life of spool.
For achieving the above object, the technical solution adopted in the utility model is: a kind of single seat sleeve adjusting valve, comprise valve body, valve seat, spool, valve rod, valve gap, sleeve and filler assembly, and described spool is H shape, the two ends of spool are sealing surface, and spool and valve rod are detachable linkage structure.
Further technological scheme, equal built-up welding has cemented carbide on the sealing surface at described spool two ends.
In the technique scheme, described spool is connected with threaded stem, and the bottom of valve rod is arranged with spring washer and nut successively, constitutes described detachable linkage structure.
Improvements of the present utility model only are spool and valve stem part, other still can adopt existing structure.Valve spool of the present utility model selects one of them sealing surface to install when mounted earlier arbitrarily, after operation a period of time, valve core sealed cover occurs wearing and tearing when needing to change, turn around to install after only needing to use general tool that spool is pulled down and get final product, without any need for extra machining and special tool(s), thereby make working life of spool correspondingly prolong 2 times.
Because the technique scheme utilization, the advantage that the utility model compared with prior art has is:
1, the utility model becomes H shape with spool design, and sealing surface all is set at its two ends, thereby after valve moves a period of time, a sealing surface of spool occurs wearing and tearing when needing to change, turn around to install after only spool need being pulled down and get final product, thereby the working life that makes spool is corresponding to have prolonged 2 times, has also reduced the cost of valve relatively.
2, the utility model becomes H shape with spool design, under the prerequisite that guarantees its intensity and sealing surface rigidity, reduced spool middle part metal solid thickness, when this adopts foundry goods at and spool big when valve aperture, seem especially outstanding, can reduce the weight and the cost of spool effectively.
3, the utility model is simple in structure, be convenient to produce preparation, and cost is lower, is suitable for applying.

Embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment one
Shown in Fig. 3~4, a kind of single seat sleeve adjusting valve, comprise valve body 1, valve seat 2, spool 3, valve rod 4, valve gap 5, sleeve 6 and filler assembly 7, described spool 3 is H shape, the two ends of spool are sealing surface 8, and equal built-up welding has cemented carbide on the sealing surface at spool two ends, and described spool is connected with threaded stem, the bottom of valve rod is arranged with spring washer 9 and nut 10 successively, constitutes described detachable linkage structure.
Improvements of the present utility model only are spool and valve stem part, other still can adopt existing structure.Valve spool of the present utility model selects one of them sealing surface to install when mounted earlier arbitrarily, after operation a period of time, valve core sealed cover occurs wearing and tearing when needing to change, turn around to install after only needing to use general tool that spool is pulled down and get final product, without any need for extra machining and special tool(s), thereby make working life of spool correspondingly prolong 2 times.
