Description

Technical Field

[0001] The utility model relates to the technical field of air vent valves, in particular to a stable air vent valve. Background Art

[0002] Waterproof breathable valves are widely used in existing power distribution and electronic and electrical equipment fields, such as control boxes, distribution boxes, junction boxes, instruments, etc. Their main function is to prevent water or external pollution from entering the box, while also playing a role in ventilation and heat dissipation inside and outside the box.

[0003] When installing the waterproof breathable membrane of the breathable valve, a mounting hole is opened at the bottom of the valve body, and then the waterproof breathable membrane is placed inside the mounting hole, and the position of the waterproof breathable membrane is fixed by squeezing the fixing ring. After installation, the thickness of the threaded part at the bottom of the valve body will be reduced. The reduction in the pipe wall thickness of the threaded part will reduce the strength of the thread, which may cause damage to the thread during tightening or loosening, thus affecting its use.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] The utility model provides Figure 1-4 A stable breathable valve shown includes a valve body 1 and further includes:

[0023] An installation component 2 is provided on the outer wall of the valve body 1 and is used to fix the position of the valve body 1;

[0024] The hole assembly 3 includes a second air vent 302 formed at the bottom of the valve body 1. The horizontal longitudinal cross-section of the second air vent 302 is set to be T-shaped. The inner wall of the top of the second air vent 302 is provided with a first air vent 301.

[0025] A waterproof breathable membrane 4 is inserted and connected to the interior of the second breathable hole 302;

[0026] The reinforcing column 5 is inserted and connected to the inside of the second vent hole 302 , and is used to strengthen the strength of the valve body 1 .

[0027] It should be noted that the waterproof breathable membrane 4 is an existing membrane body, which is used to block the passage of water vapor when in use and allow air to pass through the membrane body; the first air hole 301 and the second air hole 302 are interconnected, so that gas can flow from the valve body 1 through the first air hole 301 and the second air hole 302; the reinforcing column 5 is made of rubber material, which has the property of being deformable and fills the gap at the connection between the reinforcing column 5 and the inner wall of the second air hole 302 by deformation, and is used to seal the connection between the second air hole 302 and the waterproof breathable membrane 4. The surface friction coefficient of rubber is relatively high, which means that it will generate greater friction when it comes into contact with other objects. This high friction makes it difficult for objects made of rubber to Sliding. When the position of the waterproof breathable membrane 4 needs to be fixed, the reinforcing column 5 is inserted into the inside of the second breathable hole 302. Because the reinforcing column 5 is made of rubber, the reinforcing column 5 cannot slide inside the second breathable hole 302, so that the waterproof breathable membrane 4 is squeezed and positioned by the reinforcing column 5; the opened second breathable hole 302 is composed of two cylindrical holes with inconsistent diameters, and the cylindrical hole at the bottom is larger than the cylindrical hole at the top. When the position of the waterproof breathable membrane 4 is fixed, the waterproof breathable membrane 4 is first moved to the inside of the bottom cylindrical hole and fit with the inner wall of the top of the bottom cylindrical hole, and then the reinforcing column 5 is moved, and the position of the waterproof breathable membrane 4 is fixed by clamping the reinforcing column 5 and the inner wall of the top of the bottom cylindrical hole.

[0028] Specifically, the mounting assembly 2 includes a first thread 204 provided at the bottom of the valve body 1, the first thread 204 is used to fix the position of the valve body 1, a straight groove 201 is provided at the top of the valve body 1, the straight groove 201 is used to rotate the valve body 1, a mounting groove 202 is provided at the bottom of the valve body 1, a sealing ring 203 is inserted and connected inside the mounting groove 202, and a through hole is provided in the middle of the reinforcement column 5, the through hole is used for gas to pass through the reinforcement column 5.

[0029] It should be noted that a first thread 204 is provided on the outer wall of the bottom of the valve body 1, which is used to connect the valve body 1 to the desired fixed position. The slotted groove 201 is used for a slotted screwdriver to penetrate the top of the valve body 1 and rotate the valve body 1 by the slotted screwdriver. The sealing ring 203 is made of rubber material and will deform when squeezed, so that when the position of the valve body 1 is fixed, the sealing ring 203 is squeezed, causing the sealing ring 203 to deform and fill the gap between it, the valve body 1 and the desired fixed position through deformation, thereby preventing gas from flowing from the connection between the valve body 1 and the desired fixed position.

[0030] Furthermore, when the position of the valve body 1 needs to be fixed, the valve body 1 is first moved to the desired position, and then the first thread 204 at the bottom of the valve body 1 is aligned with the desired fixed position, and the valve body 1 is rotated to insert the first thread 204 at the bottom of the valve body 1 into the desired fixed position. Finally, a cross screwdriver is inserted into the interior of the slot 201, and the valve body 1 is rotated by the cross screwdriver until the position of the valve body 1 is fixed. The set sealing ring 203 is located between the valve body 1 and the desired fixed position, and the connection between the sealing ring 203 and the valve body 1 and the sealing ring 203 and the desired fixed position is filled and sealed by the deformed sealing ring 203 to prevent water vapor from flowing through the connection between the three.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
