Background technique
Oil cylinder or other oily drive apparatus are widely used in various machinery, for oily drive apparatus, conventionally need fuel tank to store, in when work along with the rising of oil temperature and sneaking into of gas, fuel tank just need to carry out exhaust, same situation also appears in the equipment such as gear-box, bearing housing, prevents again oily leakage when carrying out exhaust.
But existing gas permeable devices, has a large amount of fluid excessive when reaching ventilating performance, cause the oil loss of equipment, the full oil of general hydraulic equipment moves first trimester hydraulic oil loss amount up to 15%, and to environment.
Chinese patent 201020240758 discloses a kind of bearing housing Ventilated cap, it comprises ventilative cap, double-screw bolt and oil deflector, described ventilative cap connects described double-screw bolt, described oil deflector is arranged in described double-screw bolt, described oil deflector is mazy type oil deflector, and it is one and has the disk that San road breach is arranged in dislocation.
Although said structure can reduce to a certain extent, unload oil mass, its bad adaptability, can only realize by simple adjustment disk for different operating modes, can not be widely used in various device and operating mode.
Model utility content
The purpose of this utility model is for the technological deficiency existing in prior art, and a kind of antiseepage outlet valve that can effectively realize back liquid exhaust is provided.
For realizing the technological scheme that the purpose of this utility model adopts, be:
A kind of impermeable air valve, comprise at least two impermeable gas caps that connect successively and be fixedly connected with and offer the protective hat of exhaust port with the impermeable gas cap in outside, described impermeable gas cap comprises coupling bar and is connected mother, described coupling bar comprises bottom surface and cylindrical shell, described connection mother is fixedly connected with and is provided with the connection chamber that can allow coupling bar to insert and be fixedly connected with it with cylindrical shell, on described bottom surface, be formed with oil seepage hole and the air hole of perforation, the setting of staggering of the air hole of the two impermeable gas caps that are fixedly connected with.
On described cylinder body outer wall face and the internal face of connection chamber, be respectively arranged with corresponding screw thread.
Described impermeable gas cap is convex shape structure, and described cylindrical shell and connection chamber coaxially arrange, and described oil seepage hole is formed on bottom center place, and described protective hat and connection chamber are spirally connected, and described exhaust port is arranged on the top cover center of protective hat.
Described oil seepage hole is the cone shape hole that inside diameter is less than outside diameter.
Between described oil seepage hole and the internal face of cylindrical shell, be formed with transition inclined-plane.
The base angle on described inclined-plane is at 10-30 °.
Between the inner chamber of described cylindrical shell and connection chamber, be provided with the second transition inclined-plane.
Compared with prior art, the beneficial effects of the utility model are:
Impermeable air valve of the present utility model fuel tank water tank under can extensive use earthquake working environment etc., be applicable to the liquid closed container that hydraulic oil container is breathed freely or needed nature exhaust, it realizes the effect of oil return exhaust by combined and spliced formation mazy type overall structure.For different operating modes or specific environment, can the several impermeable gas caps of Optional assembling, individual layer can stop 70% fluid to overflow, adding one deck just can make more than 98% fluid intercept again, the spelling group of simple possible, significantly improved the performance of leakage proof, the backflow oil sump tank of splash fluid, has saved oil consumption and has avoided the pollution to environment.
