Problems solved by technology

[0004] Existing pressure relief valves all use spring structure, and the pressure relief pressure can be set by adjusting the compression force of the spring; due to the resonance caused by the high-frequency vibration of the air flow, the pressure relief valve will emit ear-piercing noises during pressure relief work. The noise can only be partially eliminated and reduced by adding additional equipment such as silencer cotton and silencer, but cannot completely eliminate the noise. Moreover, due to the addition of components, not only the volume of the pressure relief valve is increased, but also the volume of the pressure relief valve is increased. Production cost of pressure valve

Embodiment 1

[0054] This embodiment claims to protect an overflow pressure relief valve core, figure 1 A three-dimensional appearance view of an overflow pressure relief valve core according to an embodiment of the present invention is shown, figure 2 An exploded view of the three-dimensional appearance of an overflow pressure relief valve core according to an embodiment of the present invention, such as Figure 1-2 As shown, the overflow pressure relief valve core 100 includes a mandrel 5 and a rubber spring 6. The mandrel 5 includes a longitudinal portion 501 and a transverse portion 502. The longitudinal portion 501 and the transverse portion 502 mainly have the following two design structures:

[0055] (1) The longitudinal portion 501 penetrates the transverse portion 502

[0056] like figure 2 As shown, when the longitudinal portion 501 penetrates the transverse portion 502, the upper portion 501_1 and the lower portion 501_2 of the longitudinal portion 501 may be on the same axis...

Figure 8-12 As shown, the overflow pressure relief valve 200 includes a base 2, an upper cover 1 and an overflow pressure relief valve core 100 ...

Embodiment 3

[0075] Figure 17 is a schematic diagram showing an overflow pressure relief system according to an embodiment of the present invention, such as Figure 17 As shown, the overflow pressure relief system includes a vehicle air source 810, the overflow pressure relief valve 200 described in any one of the second embodiment, at least one on-off valve 820 and at least one air bag 830; The air inlet is connected to the vehicle air source 810, and the air outlet of the switch valve 820 is connected to the air inlet of the air bag 830; the air path in between;

[0076] When the on-off valve 820 is opened, the gas from the vehicle air source 810 first enters the air receiving chamber 7 of the overflow pressure relief valve 200; if the air pressure of the vehicle air source 810 is higher than the pressure value corresponding to the rubber spring 6 in the overflow pressure relief valve 200 , then the mandrel 5 of the relief valve core 100 moves upward, and the overflow port of the reli...

Abstract

The invention discloses an overflow decompression valve element, an overflow decompression valve and an overflow decompression system. The overflow decompression valve element comprises a spindle anda rubber spring, the spindle comprises a longitudinal part and a horizontal part, the longitudinal part penetrates through or does not penetrate through the horizontal part; if the longitudinal part penetrates through the horizontal part, the rubber spring can be arranged on the longitudinal part in a sleeving mode and flexibly abuts against the surface of the horizontal part; and if the longitudinal part does not penetrate through the horizontal part, the rubber spring can be arranged on the surface of the horizontal part opposite to the longitudinal part or arranged on the longitudinal partin a sleeving mode and flexibly abuts against the surface of the horizontal part. According to the overflow decompression valve element, the overflow decompression valve and the overflow decompressionsystem, noise generated by high-frequency vibration of gas in the decompression process can be eliminated directly and completely, additional components such as a soundproof sponge and a silencer arenot required to add additionally.

Description

technical field [0001] The invention relates to the technical field of air bag inflation, in particular to an overflow pressure relief valve core, an overflow pressure relief valve and an overflow pressure relief system. Background technique [0002] At present, the air bag system has been widely used in the field of car seats. On the one hand, the comfort of the human body can be improved by controlling the expansion degree of the air bag. Support, shoulder support, etc.; on the other hand, the massage function of the human body can be realized by controlling the frequency of inflation and inflation of the air bag. [0003] Commercial vehicles have their own air source, and their air source pressure ranges from 0.8MPa to 1.0MPa; the working pressure of seat support and massage air bags ranges from 0.04MPa to 0.06MPa; it can be seen that the on-board air source pressure of commercial vehicles is much greater than that of supporting air. The bearing capacity of the bag and t...
