Specific implementation

[0021] In order to make the technical means, creation features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific implementation.

[0022] Please refer to Figures 1-5 The utility model provides a kind of technical scheme: a kind of sewage emission reduction pressure test equipment, including water storage tank 1, the top of water storage tank 1 is provided with liftable lifting plate 2, door-shaped fixed frame 3 is installed on lifting plate 2, fixed pipe 4 is inserted and connected on the left side of fixed frame 3, first hydraulic rod 5 is fixedly installed on the right side outer wall of fixed frame 3, the telescopic end of first hydraulic rod 5 is inserted and connected fixed frame 3, and sealing cover 6 is fixedly installed at the telescopic end of first hydraulic rod 5 and the right end of fixed pipe 4.

[0023] The center of lifting plate 2 is provided with mouth, support plate 7 located in mouth is fixedly installed on the top of water storage tank 1, V-shaped object plate 8 is fixedly installed on the top end of support plate 7, pipe body 9 is placed on the top of object plate 8, object plate 8 can provide the placement position of pipe body 9, then the position height of lifting plate 2 is adjusted according to the diameter of pipe body 9, so that the height of sealing cover 6 at both ends of lifting plate 2 is adjusted. When the center of sealing cover 6 and the center of pipe body 9 are located on the same horizontal axis, control first hydraulic rod 5 to push the sealing cover 6 at its output end to be close to pipe body 9, then push pipe body 9 to be close to another sealing cover 6, finally pipe body 9 can be clamped between two sealing covers 6, so that the plugging of both ends of pipe body 9 is completed.

[0024] The left end of the top of the lifting plate 2 is fixedly provided with an air pump 13, and an air pipe 14 is fixedly connected between the output end of the air pump 13 and the fixed pipe 4. The left end of the top of the lifting plate 2 is also fixedly provided with a water pump 15. The top of the left end of the water storage tank 1 is penetrated by a connecting pipe 18 extending to the bottom of the inner cavity of the water storage tank 1 without contacting the bottom. The inner part of the connecting pipe 18 is tightly penetrated by a water inlet pipe 16 extending through the lifting plate 2 and communicating with the fixed pipe 4. The output end of the water pump 15 communicates with the water inlet pipe 16. The top of the fixed pipe 4 is fixedly provided with a water outlet pipe 17. Valves are arranged on the air pipe 14, the water inlet pipe 16 and the water outlet pipe 17, and the valves can control the flow of the medium in the air pipe 14, the water inlet pipe 16 and the water outlet pipe 17.

[0025] The left end of the fixed pipe 4 is fixedly provided with an air pressure gauge 12, by which it can be detected whether the pipe body 9 has the problem of air leakage. During the detection, water is injected into the fixed pipe 4 through the water inlet pipe 16, so that the water fills the entire fixed pipe 4 and the pipe body 9, which can squeeze out the air in the pipe body 9. When the water flows out of the water outlet pipe 17, the valves on the water inlet pipe 16 and the water outlet pipe 17 are twisted to close. After the water injection is completed, it is observed whether there is water seepage on the surface of the water pipe and each connection part. If there is water seepage, the water seepage position is marked, and the pressure detection is performed again after the repair.

[0026] Then the air pump 13 is operated and the valve on the air pipe 14 is opened. The internal pressure of the pipe body 9 is increased by injecting gas into the pipe body 9. During the gas injection process, the reading of the pressure gauge is closely observed, and the gas injection speed is controlled. According to the relevant standard or design requirement, the pressure in the pipe body 9 is increased to the specified test pressure value. Generally, the test pressure is about 1.5 times the working pressure of the pipe body 9, but not less than 0.6 MPa.

[0027] After reaching the test pressure, the gas injection is stopped, the air inlet valve is closed, and the pressure is kept stable. The pressure is kept for a period of time, which can be 1-2 hours. During this period, the reading of the pressure gauge is carefully observed whether it decreases, and at the same time, each part of the pipe body 9, including the pipe body, the joint and the weld, is checked whether there is any sign of gas leakage. Soap water or special leak detection liquid can be applied to the suspected parts. If there are bubbles, it indicates that there is leakage. After the pressure maintaining time is over, the valve for discharging air is slowly opened, and the pressure in the pipe body 9 is reduced to normal pressure. Then each part of the pipe body 9 is checked again to see whether there are new leakage points or abnormal conditions caused by pressure change, so that the sealing property of the pipe body 9 can be detected.

[0028] If Figure 1 and Figure 5As shown, the right end of the fixed tube 4 is provided in an open shape, and the right end of the fixed tube 4 is in communication with the inside of the sealing cover 6. The inner wall of the two sealing covers 6 is provided in a stepped shape gradually reducing from the outside to the inside diameter, and a sealing gasket is arranged on the inner wall of each sealing cover 6. By virtue of the different sizes of the inner wall of the sealing cover 6, the two ends of the pipe body 9 of different sizes can be conveniently sleeved and sealed.

[0029] As shown in Figure 1 and Figure 2 , a second hydraulic rod 10 is fixedly installed at the center of the top of the fixed frame 3, the telescopic end of the second hydraulic rod 10 penetrates the fixed frame 3, and an inverted V-shaped extrusion plate 11 is fixedly installed at the telescopic end of the second hydraulic rod 10. The extrusion plate 11 is located directly above the storage plate 8. By controlling the second hydraulic rod 10, the extrusion plate 11 can be pushed against the top of the pipe body 9 after sealing, so that the pipe body 9 is more stable during detection.

[0030] As shown in Figure 3 and Figure 4 , four positioning pipes 19 extending to the top of the water storage tank 1 are fixedly installed at the four corners of the inner cavity of the water storage tank 1. Four positioning rods 20 are fixedly installed at the four corners of the bottom of the lifting plate 2. The four positioning rods 20 are respectively movably inserted into the corresponding positioning pipes 19. By the insertion and cooperation of the positioning rods 20 at the bottom of the lifting plate 2 and the positioning pipes 19 in the water storage tank 1, the lifting plate 2 can be more stable during height adjustment, thereby avoiding the inclination and shaking of the lifting plate 2.

[0031] As shown in Figure 1 and Figure 2 , two third hydraulic rods 21 are fixedly installed on the two sides of the water storage tank 1. The telescopic ends of the two third hydraulic rods 21 are fixedly connected to the two ends of the bottom of the lifting plate 2. A water inlet pipe 22 in communication with the inside of the water storage tank 1 is fixedly installed at the top of the front of the water storage tank 1. A drain pipe 23 in communication with the inside of the water storage tank 1 is fixedly installed at the bottom of the front of the water storage tank 1. By controlling the third hydraulic rod 21, the position height of the lifting plate 2 can be adjusted, so that the position of the sealing cover 6 is aligned with the two ends of the pipe body 9.

[0032] Although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution. The description of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
