Description
Technical field
The utility model belongs to controlling component, specifically is meant a kind of waterproof vent valve of being made by metallic material.
Background technique
The waterproof vent valve that metallic material is made is widely used in the electronic equipment, the tank that for example heating value is big, air pressure sharply raises, battlebus etc., waterproof vent valve can prevent that extraneous water from entering in the electronic equipment, also can keep the inside and outside air pressure balance of electronic equipment, waterproof vent valve has guaranteed the proper functioning and the working life of electronic equipment.
At present, the waterproof and breathable valve technology is still not mature enough, has had a strong impact on the proper functioning of electronic equipment, has shortened the working life of electronic equipment.
Summary of the invention
The technical problems to be solved in the utility model provides and a kind ofly installs closely, waterproof and the good waterproof vent valve of air permeable effect.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of novel waterproof air previous valve, comprise the valve body and the lid that are installed on the material installed, be provided with groove on valve body top, waterproof ventilative layer is installed in groove, the through hole of gas communication inside and outside valve body lower end is provided with valve body, described lid and valve body are interference fit, and the valve body lower portion close installation is on material installed.
As the improvement to such scheme, above-mentioned bottom portion of groove is provided with O type groove, on O type groove O RunddichtringO one is installed, and waterproof ventilative layer is located on the O RunddichtringO two, and lid compresses waterproof ventilative layer in valve body; Described valve body and lid are provided with the vent that communicates.
As further improvement of these options, above-mentioned valve body lower end is a thread section, and thread section passes material installed and cooperates installation with the nut of material installed opposite side.
Further, the installation end face of above-mentioned valve body and material installed is provided with mounting groove, is provided with O RunddichtringO two in mounting groove.
The utility model reasonable in design, lid and valve body are interference fit, and lid in groove, can not get loose waterproof ventilative layer the waterproof ventilative layer close installation simultaneously, guaranteed the waterproof and the ventilate function of waterproof vent valve, effectively electronic equipment has been protected; Valve body lower portion is installed on the material installed by being threaded, and connects firmly, closely, has both prevented from that valve body from getting loose to drop, and has prevented that also extraneous water from entering in the electronic equipment, guaranteed the working life of waterproof vent valve and electronic equipment.
Description of drawings
Fig. 1 is the utility model decomposition texture front elevational schematic.
Fig. 2 is the utility model mounting structure schematic internal view.
Embodiment
For the ease of it will be appreciated by those skilled in the art that the utility model is explained in further detail below in conjunction with accompanying drawing and embodiment.
Shown in Fig. 1～2, a kind of novel waterproof air previous valve, comprise valve body 1, lid 2 and waterproof ventilative layer 3, valve body 1 and lid 2 adopt metallic material to make by machining, valve body 1 is installed on the material installed 6, material installed 6 can be airtight casing or housing etc., be provided with groove 13 on valve body 1 top, be provided with O type groove 15 in groove 13 bottoms, on O type groove 15, O RunddichtringO 1 is installed, O type groove 15 can partly encase O RunddichtringO 1, and O RunddichtringO 1 can increase the seal of valve body 1 and lid 2; Waterproof ventilative layer 3 is located on the O RunddichtringO 1; lid 1 is an interference fit with valve body 2; lid 2 compresses waterproof ventilative layer 3 in valve body 1 closely be installed in the groove 13 waterproof ventilative layer 3; thereby waterproof ventilative layer 3 can not got loose; guaranteed the waterproof and the ventilate function of waterproof vent valve, effectively electronic equipment has been protected.Be provided with through hole 14 in valve body 1 lower end, through hole 14 communicates with groove 13, is provided with the vent 5 that communicates on valve body 1 and lid 2, and gas and ambient atmos in the electronic equipment exchange by through hole 14, waterproof ventilative layer 3, groove 13 and vent 5.
In the present embodiment, valve body 1 lower end is a thread section 11, is provided with and thread section 11 nut engaged 12 at the other end of material installed 6.When valve body 1 was installed, valve body 1 thread section 11 passed material installed 6 and cooperates with nut check, thereby valve body 1 closely is installed on the material installed 6.In order to prevent that extraneous water from entering in the electronic equipment, guarantee the seal that is connected of valve body 1 and material installed 6, on the installation end face of valve body 1 and material installed 6, be provided with mounting groove 16, in mounting groove 16, be provided with O RunddichtringO 2 42.
Waterproof ventilative layer 3 is the EPTFE film, the EPTFE film is expanded PTFE again, it is a reticular structure, and surperficial every square cun of film has more than 90 hundred million micropores, and micro-pore diameter remains between 0.1～1.0 micron, little more than 10000 times more than the globule, therefore, the EPTFE film has excellent block-water performance, and the minimum globule can not pass through the EPTFE film, thereby the realization water-proof function is effectively protected electronic equipment; Simultaneously, micro-pore diameter is bigger more than 700 times than water vapour molecule, and gas molecule acts on thereby realize breathing freely like a cork by the micropore on the EPTFE film, keeps valve body 1 inside and outside air pressure balance, and then the protection outdoor electrical equipment; The EPTFE film also has stable chemical properties and very wide operating temperature range, and the EPTFE film is-40
oC～260
oThe C operating temperature range also is difficult for aging, has overlength working life, thereby has guaranteed the working life of waterproof vent valve.
The utility model reasonable in design, lid 2 is an interference fit with valve body 1, and lid 2 in groove 13, can not get loose waterproof ventilative layer 3 waterproof ventilative layer 3 close installation simultaneously, guaranteed the waterproof and the ventilate function of waterproof vent valve, effectively electronic equipment has been protected; Valve body 1 bottom is installed on by being threaded on the material installed 6, connects firmly, closely, has both prevented from that valve body 1 from getting loose to drop, and has prevented that also extraneous water from entering in the electronic equipment, guaranteed the working life of waterproof vent valve and electronic equipment.
The foregoing description only is a preferred implementation of the present utility model, and in addition, the utility model can also have other implementations.That is to say that under the prerequisite that does not break away from the present utility model design, any conspicuous replacement all should fall within the protection domain of the present utility model.
