The invention relates to a wind pressure conversion device for a metal roof wind uplift resistance test system. The wind pressure conversion device is used for solving the technical problems that an existing valve plate structure is not tight in sealing and cannot reach wind pressure, energy is wasted, and the switching process is slow. The wind pressure conversion device comprises a fan provided with an air inlet and an air outlet, and further comprises a first air pipe and a second air pipe, wherein one ends of the first air pipe and the second air pipe are communicated with each other, the other ends of the first air pipe and the second air pipe are communicated with the air inlet and the air outlet of the fan respectively, a first branch pipe and a second branch pipe are arranged on the first air pipe and the second air pipe respectively,an output air pipe is further arranged at the ends, which are communicated with each other, of the first air pipe and the second air pipe, one end of the output air pipe is communicated with the first air pipe, the other end of the output air pipe is used for carrying out air pressure loading on the metal roof to be detected, a first automatic valve is arranged on the section, which is between the first branch pipe and the output air pipe, of the first air pipe, a second automatic valve is arranged on the section, which is between the second branch pipe and the output air pipe, of the second air pipe, and third and fourth automatic valves are respectively arranged on the first and second branch pipes.
Description
technical field [0001] The invention relates to a wind pressure conversion device for a metal roof wind resistance test system. Background technique [0002] Metal roofing systems have been developed in my country for more than 40 years, especially in the past 20 years. With the needs of national economic development, some large public buildings in China have also begun to use metal roofing systems, such as airports and railway stations. During the widespread use of metal roofing systems, due to the rapid development and the lack of corresponding standards and specifications, the system has defects in materials, design, construction and management. The wind resistance and energy saving performance of metal roofing systems are poor. Accidents such as overturning and leakage often occur under the action. Many projects that have accidents are some large gymnasiums, airports, railway stations, etc. These landmark buildings should pay enough attention to the quality control, but...
