Embodiment
Preferred embodiment of the present utility model is described below in conjunction with the accompanying drawings.
As Figure 1-3, a kind of stop valve of the present utility model, including valve body 1, cut-off valve core is provided with valve body 1
2, cut-off valve core 2 includes valve core case 21, closure 22, closure bar 23 and spring 24, and valve core case 21 is U opening shape, close
Capping 22 and closure bar 23 are arranged in valve core case 21, and one end of closure bar 23 is connected with closure 22, closure bar
23 other end is each passed through valve core case 21U shapes bottom and valve body 1, and screw thread between the other end of closure bar 23 and valve body 1
Connection, spring 24 are set on closure bar 23, and valve opening 3, valve core case 21U shape openings are provided with valve core case 21U shapes two side
Both ends be also respectively provided with regulating bolt seat 4, regulating bolt 5 is movably set with regulating bolt seat 4, is set in regulating bolt 5
Baffle plate 6 is equipped with, the top of valve body 1 is additionally provided with liquid outlet 8.
Regulating bolt 5 passes through regulating bolt seat 4, and one end of regulating bolt 5 is arranged on valve core case 21U shape open interiors, adjusts
The other end of section bolt 5 is arranged on valve core case 21U shape open outsides, and screw thread connects between regulating bolt 5 and regulating bolt seat 4
Connect, 4 position in valve core case 21U shapes of adjustment regulating bolt seat can be reached by the position of controllable register 6, so as to limit and adjust
Throttling body is by ending the pressure of valve core 2, and closure bar 23 is slidably arranged in valve core case 21, with the increasing of Fluid pressure
Greatly, the compression spring 24 of closure 22 is promoted, the valve opening 3 for being easy to fluid different from valve core case 21U shapes two side flows out, valve opening 3
It is symmetricly set on valve core case 21U shapes two side, makes to keep the pressure of valve core case 21U shapes two side identical during flow of fluid, have
Stable beneficial to Fluid pressure, the diameter of valve opening 3 is less than the thickness of closure 22, and closure 22 can be prevented to be moved to the position of valve opening 3
When, shift and be caught in valve opening 3, one end of spring 24 is fixedly connected with valve core case 21U shapes bottom, the other end of spring 24 with
