Description

Technical Field

[0001] The utility model relates to the technical field of pipelines, in particular to a municipal pipeline. Background Art

[0002] A pipeline is a device connected by pipes, pipe connectors and valves for conveying gas, liquid or fluid with solid particles. Usually, the fluid is pressurized by blowers, compressors, pumps and boilers, and then flows from the high-pressure part of the pipeline to the low-pressure part. It can also be conveyed by the fluid's own pressure or gravity.

[0003] Most of the existing municipal water pipes are connected and fixed with multiple sets of bolts and flanges. During installation, the bolts need to be aligned with the flange mounting holes one by one, which is time-consuming and labor-intensive, affecting work efficiency. In addition, during the use of municipal water pipes, it is inevitable to close the valve. When the high-flow liquid is suddenly stopped by closing the valve, a water hammer effect will occur, which will cause huge vibration force, which will cause the installation bolts to loosen in the long run, resulting in water leakage. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a municipal pipeline to solve the technical problems in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a municipal pipeline, comprising a pipe body, wherein a male ring and a female ring are respectively provided at both ends of the pipe body, buffer components are provided on both sides of the outer surface of the pipe body, and a mounting tube is provided on one side of the outer surface of the pipe body, a screw rod is provided inside the mounting tube, a threaded block is provided on the outer surface of the screw rod, and a clamp is fixed on one side of the threaded block.

[0006] Furthermore, the buffer assembly includes a fixed cylinder, an air cylinder is provided inside the fixed cylinder, a piston rod passes through the bottom of the air cylinder, and a piston plate located inside the air cylinder is fixed to the top of the piston rod, and a pressure plate is provided at the bottom end of the fixed cylinder.

[0007] By adopting the above technical solution, when the water hammer effect produces an impact, the pressure plate can squeeze the piston plate through the piston rod after being subjected to force, and the piston plate compresses the gas in the gas cylinder, thereby buffering the impact force, reducing the damage and vibration caused by the water hammer effect to the pipeline.

[0008] Furthermore, a first magnetic block is disposed on the top of the pressure plate, and a second magnetic block is disposed on the bottom of the air cylinder, and the positive poles of the first magnetic block and the second magnetic block are opposite to each other.

[0009] By adopting the above technical solution, according to the principle that like repels like, a repulsive force will be generated between the first magnetic block and the second magnetic block, thereby buffering the impact force caused by the water hammer effect.

[0010] Furthermore, the male ring is matched with the female ring, and a sealing gasket is provided on the inner wall of the female ring.

[0011] By adopting the above technical solution, the male ring is inserted into the inner side of the female ring, and the sealing gasket improves the sealing performance between the two.

[0012] Furthermore, one side of the male ring and the end of the clamp are both sloped.

[0013] By adopting the above technical solution, the sloped design can guide the force. When the clamp squeezes the male ring, the male ring can exert pressure on the sealing gasket, thereby improving the sealing and firmness.

[0014] Furthermore, a knob is fixed to the end of the screw rod.

[0015] By adopting the above technical solution, the staff can make it more convenient to rotate the screw rod by turning the knob.

[0016] Furthermore, the clamps are provided in four groups, and the four groups of clamps are distributed in a ring shape.

[0017] By adopting the above technical solution, the device can be more stable, firm and not easy to fall off after installation.

[0018] Furthermore, a notch is provided on one side of the mounting tube, and the outer surface of the screw rod is coated with lubricating oil.

[0019] By adopting the above technical solution, the notch facilitates the smooth up and down movement of the clamp, and the lubricating oil can make the screw rod and the threaded block engage more smoothly.

[0020] In summary, the utility model mainly has the following beneficial effects:

[0021] 1. The utility model is provided with a female ring, a male ring, a screw rod, a threaded block and a clamp. When connecting the pipes, the male ring is first inserted into the female ring, and then the screw rod is rotated, so that the threaded block drives the clamp to move toward the male ring. Since the end of the clamp and one side of the male ring are sloped, when the two slopes meet, a lateral force is generated, which in turn presses the male ring, so that the male ring presses toward the sealing gasket, greatly improving the sealing performance and installation effect.

[0022] 2. The utility model is provided with a buffer component. When the water hammer effect occurs due to the sudden closing of the valve, the impact force of the water flow will squeeze the pressure plate, so that the piston rod drives the piston plate to pressurize the air inside the cylinder. Under the action of air resistance, the impact force of the water hammer effect can be buffered, and after the pressure plate moves, the first magnetic block moves closer to the second magnetic block. Since the magnetic blocks of the same pole repel each other, the impact force can be buffered again through the repulsive force, which greatly improves safety. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] 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. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0029] The following describes an embodiment of the utility model based on its overall structure.

[0030] Embodiment 1: A municipal pipeline, such as Figure 1-Figure 4 As shown, it includes a tube body 1, and a male ring 2 and a female ring 4 are respectively provided at both ends of the tube body 1. The male ring 2 is adapted to the female ring 4, and a sealing gasket 5 is provided on the inner wall of the female ring 4. The male ring 2 is inserted into the inner side of the female ring 4, and the sealing gasket 5 improves the sealing between the two. A mounting tube 6 is provided on one side of the outer surface of the tube body 1, and a screw rod 7 is provided inside the mounting tube 6. A threaded block 8 is provided on the outer surface of the screw rod 7, and a clamp 9 is fixed on one side of the threaded block 8.

[0031] See also Figure 1 , Figure 2 and Figure 4 In the above embodiment, a knob 10 is fixed to the end of the screw rod 7, and the staff can use the knob 10 to make it more convenient for the screw rod 7 to rotate.

[0032] See also Figure 1 , Figure 2 and Figure 4 In the above embodiment, there are four groups of clamps 9, and the four groups of clamps 9 are distributed in a ring shape, so that they are more stable and firm after installation and are not easy to fall off.

[0033] See also Figure 1 , Figure 2 and Figure 4 In the above embodiment, a notch is provided on one side of the mounting tube 6, and the outer surface of the screw rod 7 is coated with lubricating oil. The notch facilitates the smooth up and down movement of the clamp 9, and the lubricating oil enables the screw rod 7 and the threaded block 8 to engage more smoothly.

[0034] Embodiment 2: In order to improve the sealing and the firmness after installation, the embodiment 2 is improved on the basis of the embodiment 1. Figure 1 , Figure 2 and Figure 4 One side of the male ring 2 and the end of the clamp 9 are both sloped. The sloped design can guide the force. When the clamp 9 squeezes the male ring 2, the male ring 2 can exert pressure on the sealing gasket 5, thereby improving the sealing and firmness.

[0035] Embodiment 3: In order to prevent the impact force of the water hammer effect from damaging the pipeline and causing the bolts to loosen, the embodiment 3 is improved on the basis of the embodiment 1. Figure 1-Figure 3 , buffer components 3 are provided on both sides of the outer surface of the pipe body 1, and the buffer component 3 includes a fixed cylinder 301, an air cylinder 302 is provided inside the fixed cylinder 301, a piston rod 303 penetrates the bottom of the air cylinder 302, and a piston plate 307 located inside the air cylinder 302 is fixed to the top of the piston rod 303, and a pressure plate 304 is provided at the bottom end of the fixed cylinder 301. When the water hammer effect produces an impact, the pressure plate 304 is subjected to force and can squeeze the piston plate 307 through the piston rod 303. The piston plate 307 compresses the gas in the air cylinder 302, thereby buffering the impact force, reducing the damage and vibration caused by the water hammer effect to the pipeline.

[0036] See also Figure 3 In the above embodiment, a first magnetic block 305 is provided on the top of the pressure plate 304, and a second magnetic block 306 is provided on the bottom of the air cylinder 302, and the positive poles of the first magnetic block 305 and the second magnetic block 306 are opposite to each other. According to the principle that like poles repel each other, a repulsive force will be generated between the first magnetic block 305 and the second magnetic block 306, thereby buffering the impact force caused by the water hammer effect.

[0037] The implementation principle of the utility model is as follows: when connecting the pipeline, the staff first inserts the male ring 2 into the female ring 4, and then rotates the screw 7, so that the threaded block 8 drives the clamping piece 9 to move toward the male ring 2. Since the end of the clamping piece 9 and one side of the male ring 2 are sloped, when the two slopes meet, a lateral force will be generated, which will then press the male ring 2, so that the male ring 2 is pressed in the direction of the sealing gasket 5 to improve the sealing performance. When the valve is suddenly closed and a water hammer effect occurs, the impact force of the water flow will squeeze the pressure plate 304, so that the piston rod 303 drives the piston plate 307 to pressurize the air inside the air cylinder 302. Under the action of air resistance, the impact force of the water hammer effect can be buffered, and after the pressure plate 304 moves, the first magnetic block 305 moves closer to the second magnetic block 306. Since the magnetic blocks repel each other with like charges, the impact force can be buffered again through the repulsive force.
