Description

technical field [0001] The invention belongs to the field of pressure regulation of gas buildings, and in particular relates to a clamping device suitable for a pressure regulating box of a gas building. Background technique [0002] With the development of China's urbanization process, more and more rural bungalows are gradually being transformed into buildings. The gas transmission and distribution system is equipped with a gas building pressure regulating box (hereinafter referred to as building pressure regulating box) in each building to undertake the important task of reducing gas from medium pressure to low pressure. With the construction process of newly built communities and rural coal-to-gas conversion, the use of building surge boxes has greatly increased, and the structural forms have also become diverse. Advanced inspection equipment puts forward higher requirements. [0003] The pressure regulating box of the building has the characteristics of small flow rat...

Problems solved by technology

In addition, the test system needs to be suitable for different types of building surge tanks produced by different manufacturers. The experimental conditions are complicated, and the interface forms and sizes are different. When the existing gas building surge tanks are tested, bolts are used. It is time-consuming and labor-intensive to connect with the pipeline, and the work efficiency is low
