Description

Technical Field

[0001] The invention relates to the technical field of building engineering, in particular to an indoor and outdoor gas pressure relief valve for a building. Background Art

[0002] In construction projects where there is a pressure difference between the indoor and outdoor areas of a building, indoor and outdoor pressure relief is an indispensable part, which has the functions of controlling and adjusting the pressure relief speed, duration, and environmental comfort. When there is a pressure difference between the indoor and outdoor areas of a building, if the pressure relief speed is not controlled and the pressure is directly released constantly, it will cause varying degrees of damage to the doors and windows of the building, and also cause serious physical discomfort to people and animals living in the pressurized space. Therefore, controlling the pressure relief speed and slowly reducing the pressure provide a gradual adaptation process for building components, people and animals.

[0003] At present, the existing indoor and outdoor pressure relief methods are completed through the valves of water supply projects. Due to the large air pressure power, when the valve is opened, the rubber gasket on the valve core will fall off due to the impact of airflow, and once the valve is opened, the speed of pressure relief cannot be adjusted, resulting in the pressure relief being completed all at once when the pressure drops rapidly. In this case, people living in the space will feel severe ear discomfort, and then experience discomfort symptoms such as dizziness. To this end, we propose a gas pressure relief valve for indoor and outdoor buildings to solve the above problems. Summary of the invention
