Abstract
The utility model discloses a hydraulic stop valve, comprising a valve body and a spool; both ends of the valve body are provided with a pipe connector; the valve body is fixedly provided with a locating pin; an adjusting end and a limit ring are integrated on the spool; the limit ring is matched with the locating pin; the advantage is that the adjusting end and the limit ring are integrated on the spool, which eliminates the baffle ring and locating ring of the traditional stop valve, so that the structure of the stop valve is simple and reliable; the assembly is convenient.
Description
Technical field
The utility model relates to a kind of valve that is used in the hydraulic fluid pipeline, especially relates to a kind of hydraulic pressure stop valve.
Background technique
The hydraulic pressure stop valve is a kind of valve relatively more commonly used in the hydraulic pipe line.Chinese patent number is that 200810081033.8 utility model patent specification discloses the utility model patent that name is called " a kind of quick formula stop valve "; Has following structure: comprise by spool, pipe joint and valve body; Be provided with by spool in the middle of the valve body; Be provided with back-up ring, positioning ring and O type circle by spool, and have corresponding big or small cylindrical hole, be provided with positioning ring and locating stud at top by spool with pipeline at the stop valve in-core.This model utility is connected on through pipe joint in the hydraulic system that needs, rotates, can realize the Kai Heguan of stop valve by spool 90 degree.Locating stud can be controlled the dowelled spanner rotation angle; And two locating studs and the angle that is wired to 90 degree by the center of circle of spool; Open or closed the utility model in only need the angle at a right angle of rotation positioning spanner to get final product, two O type circles make the utility model in use can not reveal.There is following problem in the quick formula stop valve of this structure; Structure is complicated, assembling is cumbersome.
Summary of the invention
The utility model technical problem to be solved provides a kind of hydraulic pressure stop valve simple in structure, easy to assembly.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: a kind of hydraulic pressure stop valve; Comprise valve body and spool; Described two ends of valve body is provided with pipe joint; Be set with locating stud on the described valve body, be wholely set adjustable side and limited ring on the described spool, described limited ring cooperates with described locating stud.
Described limited ring is provided with arc notch, and described arc notch has two ribs, and when limited ring rotated, locating stud was in arc notch, and locating stud cooperates with described two ribs.Only need to adopt a locating stud to get final product.
Be provided with through hole in the described spool; Described two ribs comprise first rib and second rib, and when locating stud leaned against first rib, two pipe joints on valve core through hole and the valve body were connected; When locating stud leaned against second rib, spool was blocked two pipe joints on the valve body.
Described arc notch is slightly larger than 1/4 of circumference.
Be provided with seal ring between described spool and the described valve body.
The sectional shape of described seal ring is star-like.The sealing effect of star-like seal ring is better.
Described limited ring is located in the upper wall of valve body, and the lower end of described spool is provided with back-up ring, and described back-up ring leans against on the lower wall of described valve body.
Compared with prior art, the advantage of the utility model is that adjustable side and limited ring are wholely set on spool, has saved back-up ring and positioning ring on traditional stop valve, makes the simple and reliable for structure of stop valve, assembles more convenient.
