Large-space positive pressure building personnel access transition area structure and automatic pressure adjusting method

Abstract

The invention discloses a large-space positive-pressure building personnel access transition area structure and an automatic pressure adjusting method, and the transition area structure comprises at least one first cabin for personnel to leave a positive-pressure building and at least one second cabin for personnel to enter the positive-pressure building. The first cabin body is communicated with a positive pressure building through a first pressure-bearing inner door and a first adjusting valve and communicated with the outside through a first pressure-bearing outer door and a first pressure release valve, and the second cabin body is communicated with the positive pressure building through a second pressure-bearing inner door and a second adjusting valve and communicated with the outside through a second pressure-bearing outer door and a second pressure release valve. And the first cabin body is communicated with the second cabin body through a third adjusting valve. When people need to go in and out at the same time, part of air can be transferred to the cabin body needing to be pressurized from the cabin body needing to be depressurized through the third adjusting valve, air pressure change in the cabin body is achieved in a matched mode, and energy needed to be consumed for generating the corresponding part of air is saved.

Description

technical field

[0001] The invention relates to the technical field of human settlements in a low-pressure environment, in particular to a large-space positive-pressure construction personnel entry and exit transition zone structure and an automatic pressure regulation method. Background technique

[0002] High-altitude areas are characterized by low air pressure and low oxygen content due to the thin air. People who live in this environment for a long time are prone to various altitude sicknesses, affecting work efficiency and endangering personal health. In order to solve the above problems, it is necessary to pressurize and supplement oxygen in the living and working areas of personnel, that is, to set up a positive pressure building with an internal air pressure higher than the external air pressure, and the personnel entering and leaving the positive pressure building need to pass through the transition zone as a buffer to improve human comfort performance and reduce ai...

Examples

Embodiment

[0030] see figure 1 with figure 2 , a large space positive pressure building personnel access transition zone structure, including a first cabin body 1 and a second cabin body 6, the first cabin body 1 is used as a buffer passage for people from the positive pressure building 01 to the external environment, The second cabin body 6 serves as a buffer passage for personnel from the external environment to the positive pressure building 01 . The air pressure in the positive pressure building 01 is higher than the air pressure of the external environment, and the positive pressure building 01 maintains its internal air pressure in a stable state through a pressure regulation system.

[0031] The first cabin body 1 communicates with the positive pressure building 01 through the first pressure-bearing inner door 2 and the first regulating valve 3 , and the first cabin body 1 passes through the first pressure-bearing outer door 4 and the first pressure relief valve 5 Connect with ...
