Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The following detailed description is provided for the specific embodiments of the present invention.
In an embodiment of the utility model, see fig. 1 and 2, a hinder wet, waterproof and ventilative balanced subassembly, including valve body 3, valve body 3 one side is connected with gland 1, 3 one end of valve body is equipped with diaphragm 2, the rubber coating is fixed with valve 4 in the valve body 3, the one end that gland 1 was kept away from to valve body 3 is connected with clamping ring 5, the rubber coating outside the valve body 3 is connected with sealing ring 6.
In this embodiment, diaphragm 2 is located between valve body 3 and gland 1, sealing connection between diaphragm 2 and the valve body 1, diaphragm 2 carries out positive negative pressure business turn over gas under certain pressure differential condition, and negative pressure business turn over pressure value is: 1-4kpa, and the positive pressure exhaust pressure value is: 0.3-0.9kpa, 3 inner spaces of valve body are equipped with the straight-through air release groove, 3 one end of valve body are equipped with the external screw thread, the other end of valve body 3 is equipped with the buckle structure with 1 looks adaptation of gland, valve body 3 is connected with seal chamber through the external screw thread, valve 4 is made by the flexible glue just the structural design shape of valve 4 is unlimited, valve 4 symmetry sets up in the straight-through air release groove, the internal diameter of clamping ring 5 is less than the external diameter of straight-through air release groove to carry out effective positioning to the position of valve 4, prevent that the valve from taking place the skew and influence the stability of admitting air and exhaust in the course of the work.
The working principle is as follows:
1. normal working condition (see fig. 3, the arrow line is the air flow path line)
When the gas pressure in the box body of the sealed cavity is smaller than the opening pressure value of the valve 4 set by the device, the device belongs to a normal working state, in the state, two valve 4 in the inner hole of the valve body 3 are in a closed state, namely, the gas in the box body and the gas outside the box body can not circulate, and the wet air outside the box body is prevented from entering the sealed cavity through the valve body 3 by preventing the circulation of the gas;
2. positive pressure exhaust state (see FIG. 4, the arrow line is the air flow path line)
When the gas pressure in the sealed box body is larger than or equal to the opening pressure value of the valve 4 set by the device, the device belongs to a positive pressure exhaust state. In this state, the valve 4 in the bore of the valve body 3 is in an open state. At the moment, under the action of the pressure inside the box body, the gas can jack the valve 4 in the inner hole of the valve body 3, and the gas overflows and flows out of the valve body 3 through the diaphragm 2 arranged in the valve body 3, and is quickly exhausted and decompressed; thereby reducing the air pressure in the box body and realizing the pressure balance inside and outside the sealed cavity.
3. Negative pressure intake state (see fig. 5, the arrow route is the air circulation route)
Under special conditions, a certain pressure difference can be formed between the inside and the outside of the sealed cavity body, and when the pressure difference is greater than or equal to the opening pressure value of the valve 4 set by the device, the device belongs to a negative pressure air suction state. In this operating state, the pressure outside the valve body 3 is higher than the pressure inside the sealed chamber body. At this time, the gas flows into the inner space of the valve body 3 through the diaphragm 2 built in the valve body 3, and the side valve 4 inside the valve body 3 is pushed open under the action of the air pressure, so that the gas flows in, and the pressure balance between the inside and the outside of the sealed box body is realized.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the present invention, and any modifications, equivalents, improvements, etc. made within the spirit and principles of the present invention should be included within the scope of the present invention.
