Description
Technical field
The utility model relates to a kind of hydraulic control device, particularly relates to a kind of labour-saving hydraulic pressure stop valve.
Background technique
Usually use stop valve, ball valve to realize the function of cut-out pressure oil in the hydraulic system; In order not influence the operation of system; Need under the non-stop-machine situation of system, cut off action, close and open very effort, under the bigger situation of valve latus rectum even can't close and open; Need influence system works efficient greatly with operating behind the system-down.
Summary of the invention
The utility model has overcome deficiency of the prior art, and a kind of reasonable in design is provided, open and close labour-saving hydraulic pressure stop valve.
In order to address the above problem, the utility model adopts following technological scheme:
A kind of labour-saving hydraulic pressure stop valve comprises valve body, guiding valve, controlling device and locking device, and valve body one end passes through cover plate for sealing; Be provided with guiding valve in the valve body, spool valve end is provided with damping hole, and cover plate is provided with oil duct; The guiding valve inner space is connected with filler opening with oil duct through damping hole successively, and the valve body of guiding valve below is provided with filler opening and oil outlet, difference device for installing and adjusting and locking device on the valve body; Locking device is connected with guiding valve, and controlling device is vertical with locking device.
Described controlling device comprises regulating handle, cone valve, spring A, and regulating handle is connected with cone valve through spring A, and the valve body of cone valve side is provided with drain tap.
Described locking device comprises locking handle, indicating arm and spring B, and locking handle is connected with indicating arm, and the indicating arm front end is connected with guiding valve, mounting spring B between spool valve end and the valve body, and spring B is enclosed within on the indicating arm, and the valve body of indicating arm below is provided with form.
Described regulating handle is vertical each other with locking handle.
Compared with prior art, the beneficial effect of the utility model is:
The utility model reasonable in design adopts and regulates and the locking structure combining, makes the opening and closing of stop valve become easier, effectively raises working efficiency.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
A kind of labour-saving hydraulic pressure stop valve, as shown in Figure 1, comprise valve body 3, guiding valve 2, controlling device and locking device; Valve body 3 one ends are provided with guiding valve 2 through cover plate 1 sealing in the valve body 3, guiding valve 2 ends are provided with damping hole 14; Cover plate 1 is provided with oil duct 15; Guiding valve 2 inner spaces are connected with filler opening 13 with oil duct 15 through damping hole 14 successively, and the valve body 3 of guiding valve 2 belows is provided with filler opening 13 and oil outlet 12, difference device for installing and adjusting and locking device on the valve body 3; Locking device is connected with guiding valve 2, and controlling device is vertical with locking device.
Controlling device comprises regulating handle 5, cone valve 7, spring A6, and regulating handle 5 is connected with cone valve 7 through spring A6, and the valve body 3 of cone valve 7 sides is provided with drain tap 4.Locking device comprises locking handle 8, indicating arm 10 and spring B 11; Locking handle 8 is connected with indicating arm 10; Indicating arm 10 front ends are connected with guiding valve 2, mounting spring B11 between guiding valve 2 ends and the valve body 3, and spring B 11 is enclosed within on the indicating arm 10; The valve body 3 of indicating arm 10 belows is provided with form 9, and regulating handle 5 is vertical each other with locking handle 8.
The working principle of the utility model: pressure oil enters into cover plate 1 by filler opening 13 through oil duct 15, and the damping hole 14 of process guiding valve 2 gets into another chamber of guiding valves 2 and acts on the cone valve 7 again; Under the situation that does not have to open at cone valve 7, the hydraulic fluid pressure in 2 liang of chambeies of guiding valve equates, under the effect of spring force; Guiding valve 2 separates filler opening 13 and oil outlet 12, plays by function, for guaranteeing by reliable; Rotational lock handle 8 is pushed down guiding valve 2 thereby promote indicating arm 10, locks with locking nut then; Because the diameter of indicating arm 10 is smaller, the Driving force that therefore needs is smaller, mainly is to lean on oil pressure and spring force to work by function; Indicating arm 10 plays indication and secondary locking effect, so diameter can be smaller.When needing to use open function, at first the locking nut of locking handle 8 is opened, locking handle 8 screws out; Then regulating handle 5 is screwed out, trip spring A6, spring A6 are not by compression; Under very low pressure, just can cone valve 7 be backed down, fluid is from drain tap 4 oil sump tanks, because the throttling action of the mobile and damping hole 14 of fluid; Make 2 two end faces of guiding valve pressure difference occur, guiding valve 2 moves and makes oil suction chamber and go out oil pocket UNICOM, plays open function; Indicating arm 10 moves with guiding valve 2, can represent the opening degree of guiding valve 2.
