Time, rotation valve rod handwheel, make the first hole direction of principal axis of valve rod lower end deviate from the little pipeline at common factor, vallecular cavity and inner chamber will be connected
The little pipeline of front end disconnects, and makes the direction of the second hole axle little pipeline coaxially at common factor, will connect vallecular cavity and intracavity posterior end
Little pipeline connection, at this moment on front side of spool, pressure is more than the pressure of vallecular cavity on rear side of spool, and spool is retracted in vallecular cavity, makes liquid line
Conducting；3) when closing stop valve, rotation valve rod handwheel, make the first hole direction of principal axis of valve rod lower end tubule coaxially at common factor
Road, by connecting the little pipeline connection between vallecular cavity and inner chamber front end, makes the second hole axle reversely deviate from the little pipeline at common factor, will
Connecting the little pipeline disconnection of vallecular cavity and intracavity posterior end, at this moment the pressure on front side of spool is identical with the pressure of vallecular cavity on rear side of spool, valve
Core stretches out under the effect of back-moving spring in vallecular cavity, cuts off the conducting of liquid line.
The application has the beneficial effects that: 1) by being arranged on this internal roundabout little pipeline of stop valve by the groove after spool
Chamber is connected with the entrance and exit of liquid line, then controls being turned on or off of little pipeline by the hole axle on valve rod, controls successively
On front side of spool processed, the pressure with rear side changes, and at back-moving spring under coordinating, makes spool stretch out or retraction vallecular cavity, controls liquid successively
The on and off of body pipeline, has and realizes excellent to the control of the liquid line of bigger pressure with less strength rotation valve rod
Gesture.2) the application is simple and reasonable, Miniaturizable, effectively avoids tradition stop valve volume excessive, baroque asks
Topic.3) when liquid line opens and closes, valve rod stress I is convenient controls, and extends the service life of stop valve.
Below in conjunction with embodiment accompanying drawing, the application is described in further detail.

Numbering explanation in figure: 1 handwheel, 2 valve rods, 3 little pipelines, 4 spools, 5 inner chamber front ends, 6 bodies, 7 second hole axles, 8 the
One hole axle, 9 vallecular cavities, 10 back-moving springs, 11 intracavity posterior ends, 12 location spring assemblies
Detailed description of the invention
See accompanying drawing, liquid line stop valve structure, the valve rod 2 containing body 6 and being assemblied on body and spool 4,
The inner chamber of described body 6 can connect with liquid line, and this inner chamber front end 5 connects the entrance of liquid line, and intracavity posterior end 11 connects
The outlet of liquid line, the connection between inner chamber front end 5 and intracavity posterior end 6 is by the extension and contraction control of spool 4, and this spool 4 is by one
Individual back-moving spring 10 is embedded in intrinsic vallecular cavity 9, also has the little pipeline 3 of a built-in roundabout layout in body 6, and this is little
The front end of pipeline 3 connects with the inner chamber front end 5 of body, the rear end of little pipeline divide two-way respectively with intracavity posterior end 11 and vallecular cavity 9
Connection, described valve rod 2 is fixed on body 6 by bearing, and the upper end of valve rod 2 connects handwheel 1, and the lower end of valve rod 2 is with little
Occuring simultaneously respectively in the middle part of the front center of pipeline 3 and rear end, the lower end of valve rod 2 is provided with and can connect at little pipeline front center common factor
First hole axle 8 of little pipeline, the lower end of valve rod 2 can connect the second hole axle of little pipeline with being provided with at common factor in the middle part of little pipeline rear end
7, the first hole axle 8 is vertical with the second hole axle 7 direction.
During enforcement, for the ease of controlling the folding of stop valve, described valve rod is provided with hole, location, body is provided with
The location spring assembly corresponding with this hole, location.
During use, above-mentioned liquid line stop valve structure is arranged on liquid line, make the entrance of liquid line with
Stop valve chamber body front end 5 connects, and makes the outlet of liquid line connect with stop valve chamber body rear end 11；Open stop valve
Time, rotation valve rod handwheel 1, make the first hole axle 8 direction of valve rod 2 lower end deviate from the little pipeline 3 at common factor, vallecular cavity 9 will be connected
Disconnect with the little pipeline 3 of inner chamber front end 5, make the direction of the second hole axle 7 little pipeline 3 coaxially at common factor, will connect vallecular cavity 9 with
The little pipeline 3 of intracavity posterior end 11 connects, and at this moment on front side of spool 4, pressure is more than the pressure of vallecular cavity 9 on rear side of spool, and spool 4 is retracted into
In vallecular cavity 9, liquid line is made to turn on；When closing stop valve, rotation valve rod handwheel 1, the first hole axle 8 direction making valve rod lower end is same
The axle little pipeline 3 at common factor, connects the little pipeline 3 connected between vallecular cavity 9 and inner chamber front end 5, makes the second hole axle 7 direction inclined
From the little pipeline 3 away from common factor, disconnect connecting the vallecular cavity 9 little pipeline 3 with intracavity posterior end 11, the at this moment pressure on front side of spool 4
Identical with the pressure of vallecular cavity on rear side of spool 9, spool 4 stretches out under the effect of back-moving spring 10 in vallecular cavity 9, cuts off liquid line
Conducting.
The advantage of the application is simple and reasonable, Miniaturizable, effectively avoids tradition stop valve volume excessive,
Baroque problem.When opening and closing, valve rod stress I is convenient simultaneously controls.
