Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.
Referring to fig. 1-5, the present embodiment provides a technical solution: a high anti-pollution high protection metal waterproof vent valve comprises a vent valve main body 1 and a gland 2, the gland 2 is nested at the top of the vent valve main body 1,
the ventilation valve main body 1 includes: the O-shaped sealing ring 101 and the locking nut 102 are arranged in the middle of the outer side of the vent valve main body 1 in a nested mode, and the locking nut 102 is connected to the lower portion of the outer side of the vent valve main body 1 in a threaded mode;
the gland 2 includes: ventilated membrane 201 and bleeder vent 202, ventilated membrane 201 closely laminates in the inside top of gland 2, and bleeder vent 202 is seted up in the inner wall of gland 2.
Further, the joint of the vent valve main body 1 and the gland 2 is provided with a circular ring-shaped limiting step, and the gland 2 and the vent valve main body 1 are riveted to form a circle of limiting step, so that the distance between the gland 2 and the vent valve main body 1 is reduced, and then pollutants such as external dust are prevented from entering the interior of the vent valve main body 1.
Furthermore, six air holes 202 are formed, the six air holes 202 are circumferentially and equidistantly distributed on the inner wall of the gland 2, the six air holes 202 with diameter of 1.5mm are designed on the gland 2, when the air pressure in the cavity of the main body 1 of the vent valve is larger than the outside, the air in the main body 1 of the vent valve can be instantly discharged, so that the pressure difference balance between the cavity of the main body 1 of the vent valve and the outside is ensured, meanwhile, the air holes 202 are designed on the inner wall of the gland 2, so that pollutants such as dust and the like can be prevented from entering the main body 1 of the vent valve from the top or the side wall of the gland 2, the antifouling effect is better, the whole device can be arranged at different positions such as the top, the side wall or the bottom of a client product, the use scene of the whole device is enlarged, and products can be installed by clients more conveniently.
Further, ventilated membrane 201 adopts popped polytetrafluoroethylene material, ventilated membrane 201 is the cellular structure under the microcosmic, utilize the volume size quantity level difference of gas molecule and liquid and dust granule, let the gas molecule pass through, and liquid, the dust, impurity such as pollutant can't pass through, consequently the polytetrafluoroethylene material ventilated membrane 201 after the popped has the bidirectionality, inside steam or air can freely come in and go out ventilated membrane 201 entering 1 cavity of ventilative valve main part, it is balanced with external pressure differential to keep 1 inside cavity of ventilative valve main part, thereby realize waterproof, dustproof, high anti-soil, ventilative purpose.
