Abstract
The utility model provides a novel waterproof ventilation valve. The novel waterproof ventilation valve comprises an upper cover, a body, a waterproof air-permeable film and a sealing ring. The upper cover is provided with an assembly press face and a plurality of ventilation holes. An installing face is arranged on the upper portion of the body, a hexagonal cylinder is arranged in the middle of the body, and an installing pipe is arranged on the lower portion of the body. The waterproof air-permeable film is installed on the installing face. An arc groove is formed in the connecting position of the hexagonal cylinder and the installing pipe, the sealing ring is installed in the arc groove, the smallest diameter of the hexagonal cylinder is larger than the diameter of the upper cover, threads are arranged on the outer surface of the installing pipe, and the installing pipe is communicated with the ventilation holes. According to the novel waterproof ventilation valve, because the size of the middle hexagonal cylinder is larger than that of the upper cover and the upper cover is circular, the upper cover will not suffer external force when the novel waterproof ventilation valve is installed and used, the structure is more reliable, and the function of protecting the internal waterproof air-permeable film better is achieved; through the mode that the sealing ring is installed in the arc groove, the body and an acting body can be sealed better.
Description
Technical field
The utility model relates to waterproof and breathable field, more particularly a kind of Novel water-proof air-permeating valve.
Background technique
After waterproof vent valve invents, due to distinctive effect itself, its application is more and more wider, as LED lighting field, photovoltaic field, needs the electronic device field of hot operation, accurate instrument field, outdoor electronic product scope, even field of athletic equipment, the product in these fields service precision and being all greatly improved working life after fit on waterproof vent valve.In order further to improve the utilization efficiency of waterproof vent valve, present technology is mainly the structure that is to improve waterproof and breathable membrane module, promote utilization efficiency by improving waterproof or ventilative efficiency, but because most waterproof vent valve is to be all used on more accurate product, complicated waterproof and breathable membrane module is though affected the working life of valve itself, such as assembling easily damages, valve and working body sealing problem etc., once itself there is problem in waterproof vent valve, that working body is also just easy to be damaged, therefore in solving waterproof and breathable problem, need one more easily to install, the waterproof vent valve that sealing is better.
Summary of the invention
It is a kind of by improving the means of fixation of waterproof ventilated membrane and the mounting type of seal ring to reach the waterproof vent valve of better waterproof and breathable effect that main purpose of the present utility model is to provide.
In the utility model, a kind of Novel water-proof air-permeating valve, comprises upper cover, body, waterproof ventilated membrane and seal ring, described upper cover is provided with assembling pressure surface and some vents, and described body top is provided with attachment face, middle part is provided with hexagonal prism body, bottom is provided with mounting pipe, and wherein, described waterproof ventilated membrane is arranged on described attachment face, described hexagonal prism body and described mounting pipe joint are provided with arc groove, and described seal ring is arranged in described arc groove.
In the utility model, described attachment face is used for installing described waterproof ventilated membrane, and by upper cover lid, during to body, described assembling pressure surface is corresponding with described attachment face, for being fixed described waterproof ventilated membrane.
In the utility model, described hexagonal prism body plays fixation, need to utilize instrument to carry out operation, and not fragile in order to ensure total, the minimum diameter of described hexagonal prism body is greater than the diameter of described upper cover.
In the utility model, described mounting pipe outer surface is provided with screw thread, and communicates with described vent.
The beneficial effects of the utility model are: in the utility model, assembly comprises upper cover, waterproof ventilated membrane, body and seal ring, a plane is set in upper cover, for replacing packing ring or the compressing tablet for fixing waterproof ventilated membrane of conventional waterproof vent valve technology as independent assembly, the quantity that has so just reduced assembly also just can reduce the probability of installation difficulty and damage, and because assembling pressure surface is determined film and is arranged in upper cover, can ensure the relative position of itself and body attachment face, play the effect of better fixing waterproof ventilated membrane.In the utility model, at mounting pipe and an arc groove of body joint design, this groove just can hold seal ring, in the time that waterproof vent valve is mounted on acting body, can guarantee that seal ring is unshift and be tightly around in mounting pipe, play sealing effect best between body and working body.The utility model structural stability, waterproof and breathable is effective.

Embodiment
Be preferably specific embodiment of one of the present utility model as Figure 1-3, a kind of Novel water-proof air-permeating valve, comprise upper cover 1, body 2, waterproof ventilated membrane 3 and seal ring 4, be provided with several vents 11 on upper cover 1 top, its inside arranges an assembling pressure surface 12, body is divided into three parts, top is provided with attachment face 21, middle part is provided with for fixing hexagonal prism body 22, bottom is mounting pipe 23, the place being connected with bottom mounting pipe 23 at middle part hexagonal prism body 22 is provided with arc groove 24, in the time of assembling, waterproof ventilated membrane 3 is arranged on the attachment face on body 2 tops 21, when upper cover 1 is fastened on body 2, the assembling pressure surface 12 of upper cover 1 is corresponding with attachment face 21, assistance is fixed waterproof ventilated membrane 3, seal ring 4 is arranged in arc groove 24, for seal body 2 and acting body.
In concrete enforcement, the minimum diameter of the hexagonal prism body 22 at body 2 middle parts is greater than the diameter of upper cover 1, can avoid the damage of instrument to body 2 and upper cover 1 like this in the time that use instrument is fixing, plays a protective role.
For reaching installation object, mounting pipe 23 outer surfaces are provided with screw thread, and communicate with vent 11.
When installation, waterproof ventilated membrane 3 is arranged on attachment face 21, and upper cover 1 is fixed to after body 2, assembling pressure surface 12 and the further fixing waterproof ventilated membrane 3 of attachment face 21 combination, again sealing 4 ring sets are entered to mounting pipe 23, then utilize the screw thread of mounting pipe 23 that whole waterproof vent valve is mounted on acting body, in mounting pipe 23 seal ring 4 distortion that is squeezed during deeply to working body, its surface is pressed and is played extraordinary sealing effect with the outer wall of mounting pipe 23 and working body surface, and under arc groove 24 effects, seal ring 4 can not produce the relative displacement of itself and mounting pipe 23, thereby reach best sealing effect.After installation, the heating gas of working body inside can, by entering mounting pipe 23 and waterproof ventilated membrane 3 appears working body, complete permeation functions.In the time of off working state, waterproof ventilated membrane 3 can stop moisture to enter in working body, plays a protective role.
Can find out that by narration above purpose of design of the present utility model can effectively implement.Embodiment's part has been shown the purpose of this utility model and has been implemented function and structure theme, and comprised other the replacement that is equal to.
Therefore, right of the present utility model forms the equivalence enforcement that comprises other, and concrete right scope is with reference to claim.
