The human gate system is composed of human gate, air supply system, electrical system, lighting system, sprinkler system, intercom communication system, and camera system.
It is a pressure vessel with one or more compartments. There are access doors between the compartments. The compartments can be closed and can be pressurized by compressed air. By adding and decompressing the personnel in the air pressure transition cabin, the personnel can safely enter the high pressure excavation cabin from the atmospheric pressure zone or enter the atmospheric pressure zone from the high pressure excavation cabin, and at the same time ensure the excavation The pressure of the cabin does not change, and the pressure balance is maintained.

01. A more precise stress analysis design is adopted to meet the requirements of the strength, rigidity and fatigue reliability of the passenger cabin. Equipped with a fully pneumatic pressure regulating device to ensure that the equipment can continue to work normally when it is powered off.

02. Low-voltage power supply is adopted, the equipment is more reliable, and the entry operation is safer. Technical problems.
A newly imported sensitive multi-gas analyzer is used to detect the gas in the cabin in real time.

03. The internal and external two-way control fire-fighting system is adopted, and multiple sets of fire-extinguishing devices are equipped.
Equipped with a fixed-quantity gas exchange valve with patented technology, which is accurate, safe and reliable.

04. Equipped with a new and high-efficiency muffler device, which greatly reduces the noise at the field boundary and improves the comfort of the personnel entering the cabin.
