Therefore, a centralized air supply system is generally used now, equipped with special screw air compressors, cold dryers and gas storage tanks. The machine room of the centralized air supply system can be far away from the production site and connected to the corresponding equipment through seamless aluminum pipes. At the same time, the valve setting facilitates maintenance. The large-flow air compressor can ensure stable air pressure, and the action of the equipment air cylinder can be timely and accurate.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 2 The utility model provides a centralized air supply system with automatic pressure regulation and matching of branch line pressure, including a screw air compressor 1, the outer side of the screw air compressor 1 is connected to a wet tank air storage tank 4 through a pipeline, a pressure relief valve 3 is installed on the top of the wet tank air storage tank 4, a pressure gauge 2 is arranged on the outer side of the wet tank air storage tank 4, an automatic drain valve 6 is installed on the outer side of the wet tank air storage tank 4, a filter 5 is connected to the outer side of the wet tank air storage tank 4 through a pipeline, a cold dryer 7 is connected to the outer side of the filter 5 through a pipeline, a valve 8 is connected to the outer side of the cold dryer 7 through a pipeline, a dry tank air storage tank 9 is connected to the outer side of the valve 8 through a pipeline, a pipeline conveying pressure fluctuation suppressor 10 is connected to the outer side of the pipeline conveying pressure fluctuation suppressor 10, a fluctuation suppressor connecting device 12 is installed, a supporting device 13 is fixed to the outer side of the wet tank air storage tank 4, and a gas processing mechanism box 11 is connected to the outer side of the wet tank air storage tank 4 through a pipeline;

[0023] The fluctuation suppressor connecting device 12 includes a mounting shell 121, a return spring 122 is arranged on the inner wall of one side of the mounting shell 121, one end of the return spring 122 is connected to a movable mounting pad 123, a positioning arc groove 124 is provided inside the mounting shell 121, a protective reinforcement sleeve 125 is fixed to the outer side of the movable mounting pad 123, a guide frame 126 is fixed to one side of the movable mounting pad 123, a positioning mounting pad 127 is fixed to one side of the guide frame 126, the mounting shell 121 and the pipeline pressure fluctuation suppressor 10 are fixedly connected, a groove matching the size of the positioning mounting pad 127 is provided inside the mounting shell 121, a connecting slider 128 is slidably connected to the inside of the mounting shell 121 through a slide groove, and a shielding connecting pad 129 is fixed to the outer side of the connecting slider 128.

[0024] During the use of the device, when the flow rate of one of the branch pipes on the outside of the dry tank gas storage tank 9 suddenly changes significantly, it will affect the flow distribution on the main pipe, and correspondingly, the pressure on other branch pipes will also fluctuate. By setting a pipeline transportation pressure fluctuation suppressor 10, the corresponding branch pipe is connected to the pipeline transportation pressure fluctuation suppressor 10 and then connected to the main pipeline. The pipeline transportation pressure fluctuation suppressor 10 can be used to slow down the amplitude of the fluctuating pressure. At the same time, the outer assembly part of the pipeline transportation pressure fluctuation suppressor 10 is protected by the installation shell 121. It only needs to push the positioning installation pad 127 to drive the guide frame 126 and the protection reinforcement sleeve 125 to move at the same time through the positioning installation pad 127, so that the protection reinforcement sleeve 125 can be movably sleeved on the outside of the pipeline transportation pressure fluctuation suppressor 10 connected to the pipeline. At this time, the protection reinforcement sleeve 125 and the installation shell 121 are both connected to the pipe. The outer side of the pipeline is fitted, and one side of the positioning mounting pad 127 is movably inserted into the groove of the mounting shell 121.

The protective reinforcement sleeve 125 and the mounting shell 121 can improve the protection performance of the outer pipeline assembly structure of the pipeline transportation pressure fluctuation suppressor 10, thereby achieving the effect of reducing the amplitude of the fluctuating pressure, thereby achieving the purpose of automatic pressure regulation and matching of the branch pressure.

The gas processing mechanism box 11 can be used for gas processing.
