Technical Field
[0001] The utility model relates to the technical field of air compressor anti-leakage, in particular to a low-pressure air step-down anti-leakage device. Background Technique
[0002] An air compressor is a device used to compress gas. The air compressor is similar in structure to a water pump. Most air compressors are reciprocating pistons, rotary vanes or rotary screws. Centrifugal compressors are very large applications. According to the working principle, it can be divided into three categories: positive displacement type, dynamic type (speed type or turbine type), and thermal type compressor.
[0003] When the air compressor is in use, the leakage of compressed air usually occurs between pipe sections and at the connection between the pipeline and the equipment. Therefore, high-quality pipeline accessories are used for connection. However, after long-term use after connection, loosening may occur due to external influence and workpiece fatigue. Therefore, it needs to be improved and then re-limited for anti-leakage operation. Content of the Utility Model

When the flange is installed in the second fixing block and the first fixing block for limit closing, the connection between the second fixing block, the first fixing block and the flange is closed and sealed by the first sealing gasket and the second sealing gasket.
[0013] Preferably, a second limiting rod is welded to the top surface of the second fixing block, a first limiting rod is slidably sleeved on the second limiting rod, and the top surface of the first limiting rod is welded in the mounting bracket. By sliding the first limiting rod on the second limiting rod, the second fixing block is connected to the mounting bracket through the second limiting rod and the first limiting rod, so as to install and limit the second fixing block.

[0023] Embodiment 1
[0024] As Figures 1-3 shown, a low-pressure gas step-down and leakage prevention device proposed by the present utility model includes a base 2, a mounting frame 6, an air compressor body 11 and a second fixing block 16,
[0025] The top surface of the base 2 is welded with a mounting frame 6 and a first fixing block 15;
[0026] An intake pipe 10 and an outlet pipe 12 are installed on the air compressor body 11. A first connecting pipe 5 is installed on the intake pipe 10 through a flange 14, and a second connecting pipe 13 is installed on the outlet pipe 12 through a flange 14. The flange 14 is arranged in the first fixing block 15;
[0027] The second fixing block 16 is sleeved on the flange 14;
[0028] A screw rod 7 is installed in the mounting frame 6 by means of threading.
[0029] A mounting block 1 is installed on the bottom end surface of the air compressor body 11, and the mounting block 1 is installed on the base 2 through a bolt 3. By installing the mounting block 1 on the bottom end surface of the air compressor body 11, the air compressor body 11 is installed on the base 2 through the cooperation of the mounting block 1 and the bolt 3.
[0030] The bottom end surface of the base 2 is welded with support blocks 4. There are four support blocks 4 in total, and the four support blocks 4 are distributed in a rectangular array relative to the base 2. The base 2 is installed and fixed through the support blocks 4.
[0031] A first sealing gasket 18 is fitted and installed on the inner wall of the second fixed block 16, and a second sealing gasket 19 is fitted and installed on the inner wall of the first fixed block 15. When the flange 14 is installed in the second fixed block 16 and the first fixed block 15 for limit closing, the connection between the second fixed block 16 and the first fixed block 15 and the flange 14 is closed and sealed by the first sealing gasket 18 and the second sealing gasket 19.
[0032] Based on Embodiment 1: When a person uses the air compressor body 11 by connecting the equipment through the first connecting pipe 5 on the intake pipe 10 and the second connecting pipe 13 on the outlet pipe 12, when the connection of the pipeline is connected by the flange 14, when the flange 14 is installed in the second fixed block 16 and the first fixed block 15 for limit closing, the connection between the second fixed block 16 and the first fixed block 15 and the flange 14 is closed and sealed by the first sealing gasket 18 and the second sealing gasket 19, so as to conduct secondary sealing, prevent loosening and leakage after long-term use of the connection, and meet the later use of the air compressor body 11 and the use of low-pressure gas step-down.
[0033] Embodiment 2
[0034] As Figures 1-3 shown, a low-pressure gas step-down and leakage prevention device proposed by the present utility model further includes: a base 2, a mounting bracket 6, an air compressor body 11, and a second fixed block 16 compared with Embodiment 1.
[0035] The top surface of the base 2 is welded with a mounting bracket 6 and a first fixed block 15;
[0036] An intake pipe 10 and an outlet pipe 12 are installed on the air compressor body 11. A first connecting pipe 5 is installed on the intake pipe 10 through a flange 14, and a second connecting pipe 13 is installed on the outlet pipe 12 through a flange 14. The flange 14 is arranged in the first fixed block 15;
[0037] The second fixed block 16 is sleeved on the flange 14;
[0038] A screw rod 7 is installed in the mounting bracket 6 by means of threads.
[0039] A second limiting rod 9 is welded on the top surface of the second fixed block 16. A first limiting rod 8 is slidably sleeved on the second limiting rod 9, and the top surface of the first limiting rod 8 is welded in the mounting bracket 6. By slidably sleeving the first limiting rod 8 on the second limiting rod 9, the second fixed block 16 is connected to the mounting bracket 6 through the second limiting rod 9 and the first limiting rod 8, so as to install and limit the second fixed block 16.
[0040] The bottom end surface of the screw rod 7 is welded with a limit block 17, and the limit block 17 is sleeved in the second fixing block 16. By sleeving the limit block 17 in the second fixing block 16, after the second fixing block 16 is installed and limited, when the operator rotates the screw rod 7 to move up and down in the mounting frame 6, the second fixing block 16 can be driven to move up and down by the limit block 17.
[0041] Based on Embodiment 2: When the operator uses the air compressor body 11 to reduce the low-pressure air pressure, the first limit rod 8 is slidably sleeved on the second limit rod 9, so that the second fixing block 16 is connected to the mounting frame 6 through the second limit rod 9 and the first limit rod 8, thereby installing and limiting the second fixing block 16. And by sleeving the limit block 17 in the second fixing block 16, after the second fixing block 16 is installed and limited, when the operator rotates the screw rod 7 to move up and down in the mounting frame 6, the second fixing block 16 can be driven to move up and down by the limit block 17. Thus, when the flange 14 is connected, it can be closed by the downward pressure of the second fixing block 16. Before closing, the second fixing block 16 can move up and expand to meet the use and close after the pipeline connection.
