[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0020] Example 1

[0021] The utility model provides an industrial gas pressure detection device, such as Figure 1-4 As shown, it includes a box body 1, and T-shaped tubes 2 are fixedly installed on both sides of the bottom end of the box body 1, and the two ends of the T-shaped tube 2 respectively penetrate the two sides of the box body 1 and extend to the outer wall of the box body 1, and the two ends of the T-shaped tube 2 penetrating the outer wall of the box body 1 are fixedly connected with a first connecting plate 3, and the side of the first connecting plate 3 away from the box body 1 is in contact with a second connecting plate 4, and the side of the first connecting plate 3 away from the box body 1 is fixedly installed with a circular ring 5, and the side of the second connecting plate 4 facing the first connecting plate 3 is provided with a connecting groove 6, and the inner wall of the fixing ring 8 is slidably connected with a sealing ring 7, and the outer wall of the sealing ring 7 is slidably connected to the inside of the connecting groove 6.

[0022] When connecting the airflow duct 13 and the T-tube 2, it is necessary to pass the two ends of the T-tube 2 through the two sides of the box body 1 respectively, and extend to the first connecting plate 3 on the outer wall of the box body 1 to connect with the second connecting plate 4 on the corresponding airflow duct 13. At this time, it is necessary to put the sealing ring 7 on the outer ring of the circular ring 5, and then dock the second connecting plate 4 with the first connecting plate 3, so that the connecting groove 6 wraps the sealing ring 7 and the circular ring 5, so that the gap at the connection between the first connecting plate 3 and the second connecting plate 4 is blocked by the sealing ring 7, thereby preventing gas from leaking outward from the connection between the first connecting plate 3 and the second connecting plate 4, so that the barometer 14 can better detect the air pressure inside the airflow duct 13.

[0023] like Figure 3As shown, the top and bottom ends of the first connecting plate 3 and the second connecting plate 4 are in contact with a fixing ring 8, and the inner walls of the two sides of the two fixing rings 8 are provided with through holes 9, and the bottom ends of the two sides of the fixing rings 8 are inserted with fixing blocks 10, and the inner walls of the through holes 9 are in contact with the outer walls of the fixing blocks 10, and the fixing blocks 10 are internally threaded with bolts 11, and the outer wall of the top of the bolts 11 is in contact with a connecting ring 12, and the bottom end of the connecting ring 12 is in contact with the outer wall of the fixing ring 8, and the second connecting plate 4 is fixedly installed with an airflow duct 13 on the side away from the box body 1.

[0024] After wrapping the sealing ring 7 and the circular ring 5 through the connecting groove 6, the upper and lower fixing rings 8 are respectively placed on the top and bottom ends of the first connecting plate 3 and the first connecting plate 3, and there is a protruding part on both side connecting ends of the upper and lower fixing rings 8. Through holes 9 are opened on the protruding parts on both sides of the upper and lower fixing rings 8, so that the fixing block 10 is inserted into the through hole 9 from bottom to top, so that the bottom end of the fixing block 10 is against the fixed bottom end located below, and then the connecting ring 12 is placed on the top of the upper fixing ring 8, so that the bolt 11 passes through the connecting ring 12 and is inserted into the fixing block 10, and the bolt 11 is tightened, so that the connecting ring 12 and the fixing block 10 clamp both sides of the upper and lower fixing rings 8, so that the fixing ring 8 is fixed, which is convenient for disassembly of the airflow duct 13 when the barometer 14 is inaccurate, so as to detect the airflow duct 13.

[0025] like Figure 4 As shown, the top flange of the T-tube 2 is connected with a barometer 14, both ends of one side of the box body 1 are provided with slide grooves 15, and sliders 16 are slidably connected inside the two slide grooves 15, and a fixing plate 17 is fixedly installed between the two sliders 16. A connecting hole 18 is provided on the top of one side of the box body 1, and a fixing rod 19 is inserted into the connecting hole 18. The outer wall of the fixing rod 19 is sleeved with a rectangular shell 20, and one side of the rectangular shell 20 is fixedly connected to one side of the box body 1, and a spring 21 is sleeved between the inner wall of the rectangular shell 20 and the outer wall of the fixing rod 19. The top and bottom ends of the slider 16 are both provided with mounting holes 22 on one side of the connecting hole 18, and the connecting hole 18 is communicated with the mounting hole 22. The fixing rod 19 passes through the connecting hole 18 and extends to the mounting hole 22. A glass cover is provided on the surface of the fixing plate 17, so that the staff can accurately read the gas pressure when reading the meter, without opening the box body 1. A handle is fixedly installed on one side of the fixing plate 17 close to the glass cover. When checking and repairing the barometer 14, the box body 1 can be better pulled open by the handle to check and repair the barometer 14.

[0026] The mounting rod passes through the connecting hole 18 and extends into the mounting hole 22, so that a handle is fixedly installed at one end of the mounting rod away from the box body 1. When the fixing rod 19 is pulled up by pulling the handle, the fixing rod 19 drives the spring 21 in the circular shell. Therefore, through the elasticity of the spring 21, the partition fixedly installed on the side of the fixing rod 19 near the box body 1 in the rectangular shell 20 causes the spring 21 to be compressed inside the rectangular shell 20, so that the fixing rod 19 is pulled out of the mounting hole 22, so that the handle is pulled, and the fixing plate 17 slides upward in the slide groove 15 through the slider 16. When sliding to the top, by loosening the handle, the spring 21 in the rectangular shell 20 drives the fixing rod 19 through the connecting hole 18 through its own elasticity to be inserted into the mounting hole 22 opened at the bottom end of the slider 16 for fixing, so that the staff can inspect and check the barometer 14, prevent the glass cover of the barometer 14 from being scratched, ensure clear reading of the meter, and prevent the display screen of the barometer 14 from being exposed to dust and aging in the external air.

[0027] Working principle: When using the barometer 14, by connecting the airflow duct 13 and the T-tube 2, the two ends of the T-tube 2 need to pass through the two sides of the box body 1 respectively, and extend to the first connecting plate 3 on the outer wall of the box body 1 to connect with the second connecting plate 4 on the corresponding airflow duct 13. At this time, the sealing ring 7 needs to be sleeved on the outer wall of the circular ring 5, and the second connecting plate 4 is docked with the first connecting plate 3, so that the connecting groove 6 wraps the sealing ring 7 and the circular ring 5, so that the gap at the connection between the first connecting plate 3 and the second connecting plate 4 is blocked by the sealing ring 7, thereby preventing gas from leaking outward from the connection between the first connecting plate 3 and the second connecting plate 4, thereby also The barometer 14 can better detect the air pressure inside the airflow duct 13. After the sealing ring 7 and the circular ring 5 are wrapped by the connecting groove 6, the upper and lower fixing rings 8 are respectively placed on the top and bottom of the first connecting plate 3 and the first connecting plate 3. Through the upper and lower fixing rings 8, both sides of the connecting ends have a protruding part, and the through holes 9 are opened on the protruding parts on both sides of the upper and lower fixing rings 8. The fixing block 10 is inserted into the through holes 9 from bottom to top, so that the bottom end of the fixing block 10 is against the fixed bottom end at the bottom, and then the connecting ring 12 is placed on the top of the upper fixing ring 8, so that the bolt 11 passes through the connecting ring 12 and is inserted into the fixing In the fixed block 10, the bolts 11 are tightened so that the connecting ring 12 and the fixed block 10 clamp the two sides of the upper and lower fixing rings 8, so that the fixing rings 8 are fixed, which is convenient for disassembly of the airflow duct 13 when the barometer 14 is inaccurate, so as to detect the airflow duct 13. The mounting rod passes through the connecting hole 18 and extends into the mounting hole 22, so that the end of the mounting rod away from the box body 1 is fixedly installed with a handle, so that when the fixing rod 19 is pulled up by pulling the handle, the fixing rod 19 drives the spring 21 in the circular shell, so that the fixing rod 19 is fixed on the side close to the box body 1 in the rectangular shell 20 through the elasticity of the spring 21. The installed partition compresses the spring 21 inside the rectangular shell 20, thereby pulling the fixing rod 19 out of the mounting hole 22, thereby pulling the handle to make the fixing plate 17 slide upward in the slide groove 15 through the slider 16. When sliding to the top, by loosening the grip, the spring 21 in the rectangular shell 20 drives the fixing through the connecting hole 18 through elasticity to be inserted into the mounting hole 22 opened at the bottom end of the slider 16 for fixing, so that the staff can inspect and check the barometer 14, prevent the glass cover of the barometer 14 from being scratched, ensure clear reading of the meter, and prevent the display screen of the barometer 14 from being exposed to dust and aging in the external air.
