Abstract
The invention discloses an anti-permeation air valve, comprising at least two anti-permeation air caps which are sequentially connected, and protective caps which are fixedly connected with the outside anti-permeation air caps and are provided with vent holes, wherein each anti-permeation air cap comprises a connecting bolt and a connecting nut, each connecting bolt comprises a bottom surface and a barrel, each connecting nut is fixedly connected with the corresponding barrel and is provided with a connecting cavity for allowing the corresponding connecting bolt to insert and being fixedly connected with the corresponding connecting bolt, each bottom surface is provided with through oil permeating holes and through air vents, and the air vents of two fixedly connected anti-permeation air caps are arranged in a staggered manner. The anti-permeation air valve has the beneficial effects that a single layer can be used for blocking 70% of oil from overflowing, and two layers can be used for blocking over 98% of oil, so that the anti-permeation performance is obviously improved through simple and feasible assembly, and due to the arrangement of a backflow and oil return box for splashed oil, the oil consumption is reduced, and the pollution to the environment is avoided.
Description
Technical field
The present invention relates to field of mechanical technique, particularly relate to a kind of impermeable air valve that is applicable to be built-in with the casing of liquid.
Background technique
Oil cylinder or other oily drive apparatus are widely used in various machinery, usually need fuel tank to store for oily drive apparatus, 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, places again the leakage of oil when carrying out exhaust.
But existing gas permeable devices has a large amount of fluid excessive when reaching ventilating performance, causes the oil loss of equipment, and 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 the described double-screw bolt, described oil deflector is the mazy type oil deflector, and it is a disk with three road breach of dislocation layout.
Unload oil mass although said structure can reduce to a certain extent, its bad adaptability can only realize by the simple adjustment disk for different operating modes, can not be widely used in various device and operating mode.
Summary of the invention
The objective of the invention is for the technological deficiency that exists in the prior art, and a kind of antiseepage outlet valve that can effectively realize back the liquid exhaust is provided.
For realizing that the technological scheme that purpose of the present invention adopts is:
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 the outside, described impermeable gas cap comprises coupling bar and is connected mother, described coupling bar comprises bottom surface and cylindrical shell, the described mother of connection 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, be formed with oil seepage hole and the air hole of perforation on the described bottom surface, the setting of staggering of the air hole of the two impermeable gas caps that are fixedly connected with.
Be respectively arranged with corresponding screw thread on the internal face of described cylinder body outer wall face and connection chamber.
Described impermeable gas cap is the convex shape structure, the coaxial setting of described cylindrical shell and connection chamber, and described oil seepage hole is formed on the 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 that inside diameter is less than the cone shape hole of outside diameter.
Be formed with the transition inclined-plane between the internal face of described oil seepage hole and cylindrical shell.
The base angle on described inclined-plane is at 10-30 °.
Be provided with the second transition inclined-plane between the inner chamber of described cylindrical shell and connection chamber.
Compared with prior art, the invention has the beneficial effects as follows:
But the fuel tank water tank under the impermeable air valve extensive use earthquake working environment of the present invention etc. are applicable to the liquid closed container that hydraulic oil container is breathed freely or needed the nature exhaust, and 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 several impermeable gas caps of Optional assembling, individual layer can stop 70% fluid to overflow, adding one deck just can make the fluid more than 98% intercept again, the assembly group of simple possible, significantly improved the performance of leakage proof, the backflow oil sump tank of splash fluid has been saved oil consumption and has been avoided pollution to environment.
