Embodiment 1
[0033] An embodiment of the present invention provides an air supply system, which includes: pneumatic equipment, an air supply pipeline, and a first valve; the first valve is used to communicate with the air source, and the first valve is also connected to the pneumatic equipment through the air supply pipeline Through; Pneumatic equipment is used to modulate the relative pressure of the gas in the gas supply pipeline, so that the first valve can be opened or closed, so as to control the on-off between the gas source and the gas supply pipeline, so that the flow of gas in the gas supply pipeline The relative pressure can dynamically reach and maintain within the first pressure setting range.
[0034] The gas supply system also includes a first pressure sensor. The first pressure sensor is located upstream of the first valve to monitor whether the relative pressure of the gas source gas is a positive pressure and has a certain positive pressure value. Necessary condition for t...
Embodiment 2
[0093] The second embodiment also provides a gas supply system, the gas supply system of the second embodiment describes another implementation of the first valve, the technical solution of the first embodiment also belongs to this embodiment, and will not be repeated describe.
[0094] Such as figure 2 As shown, the specific working principle is as follows:
[0095] The first valve is a negative pressure air outlet valve 36, which utilizes the feature that it can only discharge air when the outlet forms a negative pressure, so that the air supply system can always be kept in a negative pressure state. The specific structure of the negative pressure outlet valve 36 can refer to Embodiment 7 or Embodiment 8.
[0096] The negative pressure outlet valve 36 is a mechanical action structure. In order to have sufficient valve opening force, the first pressure setting range is based on the first embodiment. Under the condition that the upper limit value remains unchanged, the lowe...
Embodiment 3
[0101] The air supply system in the third embodiment is an improvement on the basis of the first embodiment. The technical content disclosed in the first embodiment will not be described repeatedly, and the content disclosed in the first embodiment also belongs to the content disclosed in the third embodiment.
[0102] Such as image 3 As shown, the first gas storage tank 9 is provided with a first air inlet 10 and a first gas outlet 11 , and there are multiple first gas outlets 11 on the first gas storage tank 9 .
[0103] In the second embodiment, the gas supply pipeline has an outdoor section and a plurality of indoor sections, the outdoor section communicates with the first air inlet 10 ; the indoor sections communicate with the first air outlets 11 in one-to-one correspondence.
[0104] Each first air outlet 11 is provided with a second one-way valve 12, the second one-way valve 12 can be a spring-type one-way valve, and its function is mainly to prevent indoor air at nor...
