[0002] Metal breather valves with protective structures are commonly used in devices that require ventilation while preventing the ingress of liquids, dust, impurities, or moisture. They are widely used in sealing systems across industries such as automotive, machinery, electronics, hydraulics, and aerospace. Metal breather valves with protective structures represent an important development direction in modern sealing and ventilation equipment.

[0003] However, existing metal breather valves may not provide a tight enough seal under negative or high pressure conditions, leading to gas or liquid leakage. Regular cleaning, inspection, and replacement of the waterproof breathable membrane are typically required, increasing equipment maintenance costs and labor intensity, and consequently affecting equipment operating efficiency. Utility Model Content

[0004] This invention provides a metal vent valve with a protective structure, which effectively prevents contaminants and water molecules from entering the valve body, improves waterproof and breathable functions, extends the service life of the vent valve, and enhances the damage resistance of the metal vent valve. This addresses the problem that existing vent valves may not have sufficient sealing, leading to gas or liquid leakage. Furthermore, the need for regular cleaning, inspection, and replacement of the waterproof and breathable membrane increases equipment maintenance costs and labor intensity, ultimately affecting equipment operating efficiency.

[0005] To prevent pollutants and water molecules from entering the valve body, improve waterproof and breathable functions, extend the service life of the breathable valve, and enhance the damage resistance of the metal breathable valve, this utility model provides the following technical solution: A metal breathable valve with a protective structure includes a tube body and a nut cap disposed at one end of the tube body. A bracket is fixedly connected to the inner wall of the tube body. The valve also includes: a fixing ring disposed at one end of the tube body, with a sealing assembly fixedly connected to one side of the fixing ring. The sealing assembly includes a rubber ring A, a rubber ring B, and a waterproof and breathable membrane. The rubber ring A is fixedly connected to the inside of one end of the tube body. A fixing pipe bracket disposed at one end of the tube body, with a rubber pad fitted onto its surface. A protective cover is fixedly connected to one end of the fixing pipe bracket, and the fixing pipe bracket is fixedly connected to one side of the fixing ring. A buckle assembly disposed on the surface of the protective cover, the buckle assembly including a pull plate, a spring, a movable column, and a fixing sleeve, with the fixing sleeve fixedly connected to the surface of the protective cover.

[0006] As a preferred embodiment of the present invention, the sealing assembly includes a rubber ring A fixedly connected to the inside of one end of the tube body, a waterproof and breathable membrane fixedly connected to one side of the rubber ring A, and a rubber ring B fixedly connected to one side of the waterproof and breathable membrane.

[0007] As a preferred embodiment of this utility model, the buckle assembly includes a fixed sleeve fixedly connected to the surface of the protective cover, a movable column fixedly connected inside the fixed sleeve, a spring sleeved on the surface of the movable column, and a pull plate rotatably connected to the top of the movable column.

[0008] As a preferred embodiment of this utility model, a rotating rod is rotatably connected to the top of the movable column, and a locking column is fixedly connected to the bottom of the movable column.

[0009] As a preferred technical solution of this utility model, the surface of the tube body is provided with a threaded structure, a rubber ring C is fitted on the surface of the tube body, the inside of the nut cap is provided with threads, a vent hole is opened on one side of the nut cap, and a dustproof net is fixedly connected inside the nut cap.

[0010] As a preferred embodiment of this utility model, the surface of the fixed pipe rack is provided with two sets of positioning holes, the surface of the fixed pipe rack is provided with two sets of ventilation mesh holes, and the surface of the rubber pad is provided with multiple fixing holes.

[0011] As a preferred embodiment of this utility model, the protective cover has two sets of fixing holes on its surface and two sets of ventilation mesh holes on its surface.

[0012] As a preferred embodiment of this utility model, the surface of the fixing ring is provided with a plurality of fixing holes, and the top of the movable column is provided with a positioning hole.

[0013] Compared with the prior art, this utility model provides a metal vent valve with a protective structure, which has the following beneficial effects:

[0014] This metal vent valve with a protective structure, through a sealing assembly, allows gas and liquid to flow through the nut cap when enhanced waterproofing and ventilation are required. The gas and liquid pass through the dustproof mesh into the pipe body, where large particulate contaminants are blocked. At one end of the pipe, the gas and liquid come into contact with rubber ring A and the waterproof and breathable membrane. The membrane blocks liquid flow while allowing gas molecules to diffuse through, and rubber ring B further tightens the seal. This effectively prevents contaminants and water molecules from entering the valve body, improving waterproofing and ventilation, extending the valve's lifespan, and enhancing its resistance to damage.

[0015] This metal breathable valve with a protective structure is set up with a snap-fit ​​assembly. When the waterproof and breathable membrane needs to be replaced, the pull plate in the snap-fit ​​assembly is pulled open by hand. The pull plate rotates through the rotating rod, which tightens the spring. The spring drives the movable column to slide upward, so that the snap-fit ​​column is pulled out from the positioning hole of the fixed pipe rack. This makes replacement and maintenance convenient, reduces maintenance costs, and extends service life. This is an important component for reducing maintenance costs. Attached Figure Description
