Description
Technical field
The utility model is related to valve body technical field, more particularly to a kind of shield type waterproof vent valve.
Background technology
The effect of waterproof vent valve is to be breathed freely in changes in environmental conditions, and greatly reduction is caused by salt corrosion
Electronics, inductor product failure, great reduction fogging and condensation, long service life and fault-free is non-maintaining in extreme circumstances,
The equipment can be allowed to have more preferable heat radiation function.
As open-air industrial product is continued to develop, outdoor electronic device, LED light fixtures, landscape lamp, automobile lamp, sealing
The equipment such as equipment, communication equipment, sensor need waterproof vent valve to lead to overbalance pressure, reduce the stress of casing sealing bar, prevent
Only buildup of pressure and damage body seal, keep good ventilative situation, it is to avoid equipment because internal gas is gathered causes pressure
Power is raised, and casing sealing bar is damaged so that internal sensitive electronic components are endangered by water and dust invasion and attack.
The protecting cover of waterproof vent valve in prior art using mosaic mode be inconvenient to dismantle, protecting cover uses inserting mode
Or snap connection is easily damaged or is broken in installation process, and existing waterproof vent valve does not shield outside
Magnetic fields, the so normal operation easily to equipment hide some dangers for.
The content of the invention
The purpose of this utility model be for prior art defect and not enough there is provided a kind of shield type waterproof and breathable
Valve, its is simple and reasonable, convenient dismounting, is hardly damaged fracture, and can shield external magnetic field.
To achieve the above object, the utility model uses following technical scheme.
A kind of shield type waterproof vent valve described in the utility model, including waterproof ventilated membrane, valve body and protecting cover, valve body bag
Hollow threaded portion and disk body section are included, through hole is formed between threaded portion and the bottom surface of disk body section, waterproof ventilated membrane fixes paving
It is disposed through, the upper end of disk body section is provided with threaded connection cylinder, and protecting cover is with being threadedly coupled cylinder threaded connection, if disk body section is provided with
Gauze screen is additionally provided with dry osculum, disk body section, gauze screen is installed between waterproof ventilated membrane and through hole, valve body and protecting cover are equal
By conductive plastics injection moulding.
Further, protecting cover is set with disk body section in the hexagonal nut matched.
Further, it is provided with the inside of disk body section in annular groove, disk body section and is additionally provided with sealing ring, the outer rim of sealing ring is embedded in annular groove
Interior, the inner ring of sealing ring is pressed on the periphery of waterproof ventilated membrane.
Further, the outer sheath of threaded portion is provided with sealing ring, and the bottom of sealing ring and disk body section offsets.
The utility model has the beneficial effect that：The utility model is threaded connecting cylinder, and protecting cover and disk body section are passed through into screw thread
It is fixedly connected, facilitates protecting cover to be dismantled from valve body, and during waterproof vent valve is installed, the lifting surface area of outer wall is larger,
It is hardly damaged or fractures；Waterproof vent valve integrally uses conductive plastics, and is equiped with gauze screen, energy in the lower end of waterproof ventilated membrane
It is enough effectively to shield external magnetic field.The utility model is simple and reasonable, convenient dismounting, is hardly damaged fracture, and can shield
External magnetic field.
