Description
Technical field
The utility model relates to a kind of valve body, particularly a kind of waterproof vent valve.
Background technique
Along with open-air industrial product is constantly to the development of intellectuality, controlledization, miniaturization, the requirement of shelter of its internal core control system to outside protective housing is also more and more higher.As outdoor lighting lamp; communications equipment (as installed the tower top antenna controller of active electronic device), sophisticated electronics etc.; substantially all more than IP68 is reached to the security level of outside protective housing, tightness problem (as internal condensation, the easy ageing failure of Stamping Steel Ribbon etc.) will be there is like this.Such as, the equipment that telecommunications industry uses subjects the impact that ambient temperature fluctuates rapidly, also can contact various particle simultaneously, and is exposed to the various weather conditions such as wind, rain, sunlight irradiation all the time and descends.Installed the equipment such as the tower top antenna of active electronic device operationally, heat can in apparatus casing accumulated inside.This will cause pressure to increase, and make housing seal bar bear larger stress.In addition, once precipitate heavy rain or high wind may cause that there's a sudden fall in temperature, form 200mbar(3psi in apparatus casing inside thereupon) even larger vacuum, this will make housing seal bar bear larger stress equally.If housing external and internal pressure can not realize balance, the water in external environment condition, moisture, dust and dirt just can enter enclosure interior by sealing off gap.This likely produces harmful effect to the performance of communications equipment, causes more maintenance work or larger reprocesses cost.
For above-mentioned situation, some current open-air industrial product shells all can be provided with the outlet valve of band breathing waterproof film, keep the external and internal pressure of product shell balanced by outlet valve, avoid water, moisture, dust and the dirt occurred in external environment condition to be entered the inside of housing by sealing off gap.
The outlet valve of existing band breathing waterproof film, its structural entity is roughly divided into valve body and breathing waterproof film two-part, the such as patent No. is 201420321984.9 authorized in Chinese utility model patent document and just provide a kind of outlet valve, comprise expanded PTFE composite membrane, valve body and protecting cover, described valve body is divided into threaded body portion and the disk body part of hollow structure, wherein disk body part is provided with cavity, a through hole is formed between threaded body portion and the bottom surface of this cavity, expanded PTFE composite membrane is laid on the bottom surface of cavity in the mode covering this through hole, and by be embedded in above-mentioned cavity and to carry out sealing pressing with the back-up ring that this cavity is integral type structure, protecting cover is erected on the end face of above-mentioned disk body part, and there is a spatial joint clearance between the end face of the bottom surface of protecting cover and disk body part.In conjunction with its Figure of description, claimant finds that the outlet valve of said structure exists an obvious technological deficiency, the expanded PTFE composite membrane be laid in its structure on the cavity bottom surface of valve body obviously will lower than cavity opening, and the end face of whole valve body is a plane, this can cause the ponding on expanded PTFE composite membrane not easily to be removed fast, affects outlet valve and uses normally.
Model utility content
The purpose of this utility model is the waterproof vent valve providing a kind of expanded PTFE composite film surface not easily ponding in order to solve above-mentioned the deficiencies in the prior art.
To achieve these goals, a kind of waterproof vent valve designed by the utility model, comprise expanded PTFE composite membrane, valve body and protecting cover, described valve body is divided into threaded body portion and the disk body part of hollow structure, wherein disk body part is provided with cavity, a through hole is formed between threaded body portion and the bottom surface of this cavity, expanded PTFE composite membrane is fixedly laid in cavity in the mode covering this through hole, protecting cover is erected in the card of above-mentioned disk body part, and there is a spatial joint clearance between the card of the bottom surface of protecting cover and disk body part, described expanded PTFE composite membrane is center arcuate configuration, the open height of its central point and cavity flushes, described card is the raised cambered surface in a center.
Above-mentioned provided a kind of waterproof vent valve, expanded PTFE composite membrane described in its structure is center arcuate configuration, the open height of its central point and cavity flushes, described card is the raised cambered surface in a center, therefore when in the card that water droplet condenses upon said structure, this water droplet can spread to the periphery of card relatively fast, shortens the time that water droplet covers expanded PTFE composite film surface, thus makes waterproof vent valve recover normal usage energy.
As further technological selection, above-mentioned valve body is the molding and forming structure of integral type.
Valve body described in above-mentioned further technological selection scheme adopts Shooting Technique to carry out integral type machine shaping, can be simplified to fix the production technology of the valve body laying expanded PTFE composite membrane, thus reduces
The cost of production of waterproof vent valve entirety.
As further technological improvement, the concrete erecting structure of above-mentioned protecting cover frame in the card of disk body part is: be furnished with boss in the periphery pressed on ring of described card, each boss is provided with attachment post, the periphery pressed on ring of described protecting cover is furnished with the attachment hole of corresponding above-mentioned attachment post, and above-mentioned attachment post is plugged to one by one in attachment hole accordingly.
The erecting structure that described in above-mentioned further Technological improvement plan, protecting cover is erected in the card of disk body part is simple.
A kind of waterproof vent valve that the utility model obtains, the expanded PTFE composite film surface not easily ponding in its structure, therefore whole waterproof vent valve is after rainwater weather, can quick-recovery normal usage energy soon.
