The on-off of big flow liquid is not necessarily to big torsion when switching valve body, improves convenience, can effectively solve asking in background technique
Topic.
To achieve the above object, the utility model provides the following technical solutions: a kind of high-pressure stop valve, including main body tube
Road, the left end of the main pipeline are water inlet, and the right end of main pipeline is water outlet, and two sides are equal up and down at the middle part of main pipeline
It is provided with circular through hole, sliding is provided with spool in circular through hole, and spool is cylindrical and the axis of central axes and main pipeline
Line is vertical, and lateral limbers is provided on the spool, and the upper circular through hole of main pipeline is welded with mounting shell, installation
It is transformation chamber inside shell, the effect both ends of mounting shell are respectively arranged with water inlet pipe and outlet pipe, and transformation chamber passes through water inlet pipe respectively
It is connected to outlet pipe with inlet and outlet, ball valve is installed on outlet pipe, mounting shell is internally provided with spring, spring
Lower end is welded on the upper surface of spool, and sealing cover is welded at the lower part circular through hole of the main pipeline, is to hold in sealing cover
Core cavity, holding core cavity is that cylindrical and central axes are overlapped with the central axes of spool.
As a kind of optimal technical scheme of the utility model, the quantity of the limbers is three, three limbers edge
Longitudinal direction is equidistantly positioned in spool.
As a kind of optimal technical scheme of the utility model, the lower end of the spool, which is located at, to hold in core cavity, outside spool
The distance between wall and the inner wall for holding core cavity are less than 0.1 millimeter.
Compared with prior art, the utility model has the beneficial effects that this high-pressure stop valve uses cylindrical spool, improve
The compressive property of spool, and then the service life of spool is improved, shut-off valve do not directly control main pipeline mesohigh liquid
Circulation, but utilize be arranged in small flow conduit ball valve control main pipeline in big flow liquid on-off, switch valve
It is not necessarily to big torsion when body, improves convenience.
