Description

TECHNICAL FIELD

[0002] Because many traditional pressure reducing devices adopt fixed pressure reducing ratio, they cannot adjust the pressure reducing degree in time according to the actual pressure change of the system. In the actual operation of the building, water pressure or air pressure experiences frequent change due to water consumption fluctuation, equipment start-stop and other factors, and the contradiction between this fixed pressure reducing setting and dynamic change directly affects the pressure reducing effect. Therefore, the conventional coping methods include increasing adjustable components in the design stage or adopting more pressure reducing devices to cope with the change. However, the disadvantages of these methods are also very obvious. Increasing adjustable components will lead to the increase of the complexity of the device, and then increase the difficulty of installation and maintenance, and also may lead to the increase of the failure rate of the system, affecting the operation reliability. While increasing multiple pressure reducing devices in the building can improve the adaptability to a certain extent, but this will also significantly increase the construction cost and occupied space, making the engineering implementation more complex, therefore, we hope to design a flow guide pressure reducing device with a novel structure to solve this problem.
