Abstract
The invention discloses a breather valve. The breather valve comprises a valve body. A valve deck is arranged above the valve body. A valve cavity is formed in the middle of the valve body. A polytetrafluoroethylene film is arranged on the top of the valve body. In the working process of the breather valve, due to the oil repellence characteristic and the water repellence characteristic of polytetrafluoroethylene materials, oil in the valve cavity can be effectively blocked in the valve cavity through the polytetrafluoroethylene film and is prevented from seeping to the outer portion of the valve body, and therefore the oil seepage prevention capacity of the breather valve is effectively improved.
Description
Technical field
The present invention relates to retarder, gearbox corollary equipment technical field, particularly a kind of inhalation valve.
Background technique
Inhalation valve is a kind of significant components be widely used in retarder, gearbox class machinery, and along with improving constantly of user demand, the service behaviour of people to inhalation valve it is also proposed higher requirement.
Although inhalation valve kind comparatively common in current mechanical field is comparatively various, but its most structure is comparatively simple, and limit due to himself structure, although existing common inhalation valve can realize gas exchanges inside and outside equipment, but inhalation valve still exists oil impregnate phenomenon in equipment running process, and oil leakage problem cannot be solved well based on existing inhalation valve self structure.
Therefore, the stronger inhalation valve of a kind of seepage-proof oil ability how is provided to be the important technological problems that those skilled in the art need to solve at present.
Summary of the invention
The object of this invention is to provide a kind of inhalation valve, the seepage-proof oil ability of this inhalation valve is stronger.
For solving the problems of the technologies described above, the invention provides a kind of inhalation valve, comprising valve body, the top of described valve body is provided with valve gap, and the middle part of described valve body has valve pocket, and the top of described valve body is provided with poly tetrafluoroethylene.
Preferably, the inwall of described valve pocket is provided with baffle plate.
Preferably, described baffle plate is at least two, and each baffle plate is crisscross arranged on the inwall of described valve pocket along valve axis direction successively.
Preferably, described baffle plate and the intermembranous distance of described teflon increase to its free end gradually from the assembling end of described baffle plate and valve pocket inwall.
Relative above-mentioned background technology, inhalation valve provided by the present invention, in its working procedure, due to the oil and water repellent characteristic of polytetrafluoroethylmaterial material self, fluid in valve pocket effectively can be intercepted in valve pocket by described poly tetrafluoroethylene, avoid fluid to infiltrate into valve body outside, thus effectively improve the seepage-proof oil ability of described inhalation valve.
In another preferred version of the present invention, the inwall of described valve pocket is provided with baffle plate.In working procedure, described baffle plate can effectively prevent the fluid in valve pocket from causing structural impact to poly tetrafluoroethylene, thus avoids teflon film body to be caused structural damage because impacting.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
The assembly structure sectional view of the inhalation valve that Fig. 1 provides for a kind of embodiment of the present invention.
Embodiment
Core of the present invention is to provide a kind of inhalation valve, and the seepage-proof oil ability of this inhalation valve is stronger.
In order to make those skilled in the art person understand the present invention program better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Please refer to Fig. 1, the assembly structure sectional view of the inhalation valve that Fig. 1 provides for a kind of embodiment of the present invention.
In a specific embodiment, inhalation valve provided by the present invention, comprises valve body 11, and the top of valve body 11 is provided with valve gap 12, and the middle part of valve body 11 has valve pocket 111, and the top of valve body 11 is provided with poly tetrafluoroethylene 112.
In working procedure, due to the oil and water repellent characteristic of polytetrafluoroethylmaterial material self, fluid in valve pocket 111 effectively can be intercepted in valve pocket 111 by poly tetrafluoroethylene 112, avoid fluid to infiltrate into valve body 11 outside, thus effectively improve the seepage-proof oil ability of described inhalation valve.
Further, the inwall of valve pocket 111 is provided with baffle plate 113.In working procedure, baffle plate 113 can effectively prevent the fluid in valve pocket 111 from causing structural impact to poly tetrafluoroethylene 112, thus avoids teflon film body to be caused structural damage because impacting.
More specifically, baffle plate 113 is at least two, and each baffle plate 113 is crisscross arranged on the inwall of valve pocket 111 along valve body 11 axial direction successively.The structure that is crisscross arranged this kind can improve further baffle plate 113 cooperatively interact after impact resistance, thus improve further it to the protective capability of poly tetrafluoroethylene.
On the other hand, the distance between baffle plate 113 and poly tetrafluoroethylene 112 increases to its free end gradually from the assembling end of baffle plate 113 with valve pocket 111 inwall.The downward-sloping structure of this kind of free end contributes to the impact resistance improving single baffle plate 113, thus ensures the protected effect of baffle plate 113 pairs of poly tetrafluoroethylenes further.
In addition, in practical set using process, valve gap 12, for thickening impact-proof structure, with the structure of available protecting valve body 11 body assembly and poly tetrafluoroethylene 112, is avoided it to be subject to external structure and is impacted or damage.
In summary, the inhalation valve provided in the present invention, comprises valve body, and the top of described valve body is provided with valve gap, and the middle part of described valve body has valve pocket, and the top of described valve body is provided with poly tetrafluoroethylene.In its working procedure, due to the oil and water repellent characteristic of polytetrafluoroethylmaterial material self, fluid in valve pocket effectively can be intercepted in valve pocket by described poly tetrafluoroethylene, avoid fluid to infiltrate into valve body outside, thus effectively improve the seepage-proof oil ability of described inhalation valve.
Above inhalation valve provided by the present invention is described in detail.Apply specific case herein to set forth principle of the present invention and mode of execution, the explanation of above embodiment just understands method of the present invention and core concept thereof for helping.It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also carry out some improvement and modification to the present invention, these improve and modify and also fall in the protection domain of the claims in the present invention.
