Abstract
The utility model discloses an anti-breakage valve belonging to a safety protective device of an oil cylinder and solving the defects of environmental pollution, difficult maintenance and large danger coefficient when the situation that an oil pipeline breaks occurs in the prior art. The anti-breakage valve comprises a valve body, wherein a plurality of oil holes are uniformly distributed on the valve body in which a valve core is arranged; the valve core in the valve body is provided with a compression spring; one end of the valve core is fixed in the valve body, and the other end is provided with two adjusting nuts; a valve is arranged on the valve core between the adjusting nuts and the valve body; and one end of the compression spring is fixed on the valve core, and the other end is fixed on the valve. The anti-breakage valve is mainly used for timely sealing oil ports to prevent the oil leakage in the oil cylinder when the pipeline of a hydraulic transmission system breaks.
Description
Technical field
The utility model belongs to a kind of Safeguard of oil cylinder, specifically, relates in particular to a kind of anti-disrumpent feelings valve.
Background technique
When hydraulic control system is worked, run into the situation that oil line pipe breaks through regular meeting, make fluid flash, thereby cause the phenomenon of environmental pollution and maintenance difficult because hydraulic oil has certain pressure this moment, when serious, even also can cause personal injury.At present, also there is not a kind of device when running into the situation that oil line pipe breaks, can convenient for maintaining, avoid environmental pollution and reduce risk factor.
Summary of the invention
In order to solve in the prior art when running into the situation that oil line pipe breaks, environmental pollution, maintenance difficult can occur and cause the big defective of risk factor, the utility model provides a kind of anti-disrumpent feelings valve.
The utility model is achieved through the following technical solutions:
A kind of anti-disrumpent feelings valve comprises valve body, and valve body is provided with several oilholes, and valve inner is provided with spool, and the spool of valve inner is provided with pressure spring; One end of spool is fixed on valve inner, and the other end is provided with the adjustment nut; The spool of adjusting between nut and the valve body is provided with valve.
Preferably be provided with outside thread on the described valve body.
Compared with prior art, the beneficial effects of the utility model are: be installed in the import and export of hydraulic jack, behind pipe breakage, valve moment closes, and makes band press fluid not spray, thereby brings convenience for the maintain and replace oil pipe, avoid environmental pollution simultaneously, improved safety coefficient greatly; Simple in structure, easy for installation.
Description of drawings
Fig. 1 is a plan view of the present utility model;
Fig. 2 is a plan view of the present utility model;
Fig. 3 is the phase diagram of the present utility model under hydraulic pipe line regular path state;
Fig. 4 is the phase diagram of the present utility model under the hydraulic pipe line breaking state.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Valve body in the drawings, 1; 2, spool; 3, pressure spring; 4, valve; 5, adjust nut; 6, outside thread; 7, oilhole; 8, cylinder tube arm; 9, the straight-through oil connection of end; 10, oil pipe.
Embodiment one: a kind of anti-disrumpent feelings valve, comprise valve body 1, and valve body 1 is provided with several oilholes 7, and valve body 1 inside is provided with spool 2, and the spool 2 of valve body 1 inside is provided with pressure spring 3; One end of spool 2 is fixed on valve body 1 inside, and the other end is provided with adjusts nut 5; The spool of adjusting between nut 5 and the valve body 12 is provided with valve 4.
The size of pressure spring 3 be must calculate during making, spring diameter, middle footpath and length accurately determined according to demand; The requirement on machining accuracy of valve 4 is very high, and surface roughness requires high.
During use, earlier valve body of the present utility model 1 top is connected with the oil inlet and outlet external stability of oil cylinder, and guarantees oil-proof.Valve 4 is in open mode when the hydraulic system proper functioning, and pressure oil flows through valve 4 along oilhole 7, the oil circuit proper functioning; When fracture took place in the oil line pipe somewhere of whole hydraulic system, this moment, the resistance of oil circuit suddenly disappeared, and in-oil cylinder oil pressure strengthens suddenly, collide valve 4, make the pressure spring 3 stressed back recompressions in the valve body 1, and pulling valve 4 closes it, pressure oil no longer flows out.At this moment, the maintenance man can change oil pipe easily, and has avoided spattering environmental pollution and the hazard to person that causes outward because of fluid.
Embodiment two: valve body 1 is provided with outside thread 6, and other is identical with embodiment one.
During use, earlier the utility model is screwed in the oil inlet and outlet inside of oil cylinder by the outside thread on the valve body 16.And then carry out one identical operations process, and reach the effect identical with embodiment one with embodiment.
Claims (2)
