Description

Technical Field

[0001] This utility model relates to the technical field of noise-absorbing pipes, and more specifically, to a multi-layer composite noise-absorbing plastic pipe. Background Technology

[0002] A pipeline is a device made up of pipes, pipe fittings, valves, etc., used to transport gases, liquids, or fluids containing solid particles. Typically, fluids are pressurized by blowers, compressors, pumps, boilers, etc., and then flow from the high-pressure area to the low-pressure area in the pipeline. They can also be transported using the fluid's own pressure or gravity. Pipelines have a wide range of applications, mainly in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, water conservancy projects, and various industrial installations. Silencing pipes are a type of pipeline that can reduce noise and lower noise pollution.

[0003] Existing technology discloses a sound-absorbing PPR water pipe. Through the design of the PPR water pipe, sound-absorbing cotton, sound insulation layer, support assembly, and connecting assembly, during connection, when two sets of connecting sleeves are fitted onto one end of a two-layer composite sound-absorbing plastic pipe assembly (PPR water pipe), the pull rod is shaken, causing the locking block at one end of the pull rod to engage inside the locking housing, resulting in a tighter connection between the locking block and the housing. Subsequently, rotating the connecting pipe allows it to pass through the connecting sleeves and be installed inside the PPR water pipe simultaneously, as the threads at both ends of the multi-layer composite sound-absorbing plastic pipe surface are opposite. This enables the PPR water pipe to achieve excellent sound absorption and quickly connect the two sets of PPR water pipes. However, the two sets of water pipes need to be connected via the threads at both ends of the connecting pipe, which places high demands on the position of the two sets of water pipes and is inconvenient for connecting adjacent pipes. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies that make it inconvenient to connect adjacent pipes, and to provide a multi-layer composite sound-absorbing plastic pipe that facilitates the connection of adjacent pipes while reducing pipe noise.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A multi-layer composite sound-absorbing plastic pipe is provided, including a first sound-absorbing pipe, a second sound-absorbing pipe, a sound-absorbing hose, and a support assembly. The first sound-absorbing pipe and the second sound-absorbing pipe are both disposed on the support assembly, and the first sound-absorbing pipe and the second sound-absorbing pipe are connected through the sound-absorbing hose.

[0007] This utility model discloses a multi-layer composite sound-absorbing plastic pipe. The positions of the first and second sound-absorbing pipes are fixed by a support component, and then the first and second sound-absorbing pipes are connected by a sound-absorbing hose. By connecting adjacent pipes with the sound-absorbing hose, further sound absorption can be achieved at the connection point. At the same time, since the two ends of the sound-absorbing hose can be offset, the relative position requirements of the first and second sound-absorbing pipes are not high, which facilitates the connection of adjacent pipes. Thus, it can reduce pipe noise while facilitating the connection of adjacent pipes.

[0008] Furthermore, the noise-reducing flexible hose is a corrugated pipe. By incorporating a corrugated pipe, the pipe expands and contracts as water flows through the connection, buffering the water flow and thus reducing noise at the connection.

[0009] Furthermore, both the first and second silencer pipes are equipped with a first connecting flange, and both ends of the silencer hose are equipped with a second connecting flange, which are connected together. The connecting flanges connect the first and second silencer pipes to the two ends of the silencer hose, respectively, reducing the problem of leakage at the pipe connections.

[0010] Furthermore, it also includes tie rods, the two ends of which are slidably connected to the two second connecting flanges respectively. By setting the tie rods, the expansion and contraction of the bellows are guided and restricted, reducing the force exerted on the bellows by the water flow velocity.

[0011] Furthermore, the tie rod is equipped with limiting components, which are located on both sides of the second connecting flange, with a sliding space between the two limiting components for the second connecting flange to slide. By setting the limiting components, the displacement of the second connecting flange is restricted, thereby limiting the extension and contraction length of the bellows and better buffering the water flow.

[0012] Furthermore, the support components are located at both ends of the first and second silencer pipes, respectively. Both ends of the first and second silencer pipes are equipped with support components, which can provide good support for the first and second silencer pipes, prevent pipe tilting, and allow for smoother water flow.

[0013] Furthermore, the support assembly includes a lifting component and a placement block. The placement block is connected to the output end of the lifting component, and the first or second silencer pipe is connected to the placement block. By setting the lifting component, the height of the first and second silencer pipes is adjustable. Simultaneously, since the lifting component is located at both ends of the first and second silencer pipes respectively, the tilt of the first and second silencer pipes can be adjusted, thereby preventing water flow obstruction on uneven ground.

[0014] Furthermore, both the first and second silencers include a threaded silencer and a drain pipe. The inner wall of the threaded silencer has a threaded structure, and the threaded silencer is sleeved outside the drain pipe. Water flows through the drain pipe, and the sound waves generated by the water flow diffuse outward, reaching the inner wall of the threaded silencer and spreading forward along the threads, thereby reducing the intensity of the sound waves and achieving noise reduction.

[0015] Furthermore, both the first and second silencers also include an asbestos pipe, which is located between the threaded silencer and the drain pipe. The asbestos pipe further reduces noise.

[0016] Furthermore, both the first and second silencing pipes also include a reinforcing pipe, which is located between the asbestos pipe and the drain pipe. By adding the reinforcing pipe, the strength of the drain pipe is increased, while simultaneously isolating the asbestos pipe and the drain pipe, preventing leakage water from seeping outwards when the drain pipe has a hidden crack.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. The present invention relates to a multi-layer composite sound-absorbing plastic pipe, which connects adjacent pipes by using a sound-absorbing flexible hose, thereby enabling further sound absorption at the connection point. Since the two ends of the sound-absorbing flexible hose can be offset, the relative position requirements of the first and second sound-absorbing pipes are not high, which facilitates the connection of adjacent pipes, thereby achieving convenient connection of adjacent pipes while reducing pipe noise.

[0019] 2. The present invention provides a multi-layer composite sound-absorbing plastic pipe, which, by setting up a lifting component, allows the height of the first and second sound-absorbing pipes to be adjustable. At the same time, since the lifting component is located at both ends of the first and second sound-absorbing pipes respectively, it can adjust the inclination of the first and second sound-absorbing pipes, thereby avoiding water flow obstruction on uneven ground.

[0020] 3. The present invention provides a multi-layer composite sound-absorbing plastic pipe, wherein the first sound-absorbing pipe and the second sound-absorbing pipe both include a drain pipe, a threaded sound-absorbing pipe and an asbestos pipe. Water flows in the drain pipe, and the sound waves generated by the water flow will diffuse outward and diffuse to the inner wall of the threaded sound-absorbing pipe, and diffuse forward along the thread, thereby reducing the intensity of the sound waves and achieving noise reduction. The noise is further reduced by setting the asbestos pipe. Attached Figure Description

[0030] Example 1

[0031] This embodiment is a first embodiment of a multi-layer composite sound-absorbing plastic pipe, such as... Figure 1 As shown, it includes a first silencer pipe 100, a second silencer pipe 200, a silencer hose 300, and a support assembly 400, such as... Figure 5 As shown, both the first silencer pipe 100 and the second silencer pipe 200 include a threaded silencer pipe 120 and a drain pipe 110, as... Figure 6 As shown, the inner wall of the threaded silencer pipe 120 is provided with a threaded structure, and the threaded silencer pipe 120 is sleeved outside the drain pipe 110. Water flows through the drain pipe 110, and the sound waves generated by the water flow will diffuse outward, diffuse to the inner wall of the threaded silencer pipe 120, and diffuse forward along the thread, thereby reducing the intensity of the sound waves and achieving noise reduction.

[0032] The first silencer 100 and the second silencer 200 are both mounted on the support assembly 400, such as Figure 1 As shown, support components 400 are located at both ends of the first silencer pipe 100 and the second silencer pipe 200, respectively. Support components 400 are provided at both ends of the first silencer pipe 100 and the second silencer pipe 200, providing good support for them, preventing pipe tilting, and ensuring smoother water flow. Figure 3As shown, the support assembly 400 includes a lifting assembly 410 and a placement block 420. The placement block 420 is connected to the output end of the lifting assembly 410, and the first silencer pipe 100 or the second silencer pipe 200 is connected to the placement block 420. By setting the lifting assembly 410, the height of the first silencer pipe 100 and the second silencer pipe 200 is adjustable. Furthermore, since the lifting assembly 410 is located at both ends of the first silencer pipe 100 and the second silencer pipe 200, the tilt of the first silencer pipe 100 and the second silencer pipe 200 can be adjusted, thereby preventing water flow obstruction on uneven ground.

[0033] like Figure 1 and Figure 2 As shown, the first silencer pipe 100 and the second silencer pipe 200 are connected by a silencer hose 300. The specific connection method can be varied, including flange bolt connection or threaded connection. For example... Figure 2 As shown, the silencing hose 300 is a corrugated pipe. By incorporating a corrugated pipe, the pipe expands and contracts as water flows through the connection, buffering the water flow and thus reducing noise at the connection.

[0034] The working principle of a multi-layer composite sound-absorbing plastic pipe in this embodiment is as follows:

[0035] The first silencer pipe 100 and the second silencer pipe 200 are placed on the placement block 420 respectively. The positions of the first silencer pipe 100 and the second silencer pipe 200 are fixed by the support assembly 400. The height and tilt of the first silencer pipe 100 and the second silencer pipe 200 are adjusted by the lifting assembly 410. The first silencer pipe 100 and the second silencer pipe 200 are then connected by a silencer hose 300. By connecting adjacent pipes using the silencer hose 300, further noise reduction can be achieved at the connection point. At the same time, since the two ends of the silencer hose 300 can be offset, the relative position requirements of the first silencer pipe 100 and the second silencer pipe 200 are not high, which facilitates the connection of adjacent pipes, thereby achieving the goal of reducing pipe noise while facilitating the connection of adjacent pipes.

[0036] Example 2

[0037] This embodiment is the second embodiment of a multi-layer composite sound-absorbing plastic pipe. This embodiment is similar to the first embodiment, except that, as shown in the example... Figure 2As shown, both the first silencer pipe 100 and the second silencer pipe 200 are equipped with a first connecting flange 210, and both ends of the silencer hose 300 are equipped with a second connecting flange 310. The first connecting flange 210 and the second connecting flange 310 are connected, and the first connecting flange 210 and the second connecting flange 310 can be connected by bolts. By connecting the first silencer pipe 100 and the second silencer pipe 200 to the two ends of the silencer hose 300 respectively through the connecting flanges, the problem of liquid leakage at the pipe connection is reduced. A sealing ring can also be installed between the first connecting flange 210 and the second connecting flange 310 to enhance the sealing effect.

[0038] It also includes a tie rod 320, with both ends of the tie rod 320 slidably connected to two second connecting flanges 310. The tie rod 320 guides and restricts the expansion and contraction of the bellows, reducing the force exerted on the bellows by the water flow velocity. Both ends of the tie rod 320 are threaded, and nuts are threaded into these threads. The nuts abut against the second connecting flanges 310, thus mounting the tie rod 320 onto the second connecting flanges 310. The middle of the tie rod 320 is a smooth rod structure. When water rapidly impacts the bellows, the second connecting flanges 310 slide on the smooth rod, thereby reducing the force exerted on the bellows by the flow velocity.

[0039] The tie rod 320 is equipped with limiting components, located on both sides of the second connecting flange 310, with a sliding space between the two limiting components allowing the second connecting flange 310 to slide. By setting the limiting components, the displacement of the second connecting flange 310 is restricted, thereby limiting the expansion and contraction length of the bellows and better buffering the water flow. Figure 2 As shown, in this embodiment, both ends of the pull rod 320 are provided with threaded structures, and the limiting component is a nut. The nut is threadedly connected to the threaded structure. The nuts are located on both sides of the second connecting flange 310, and there is a sliding space between the two nuts for the second connecting flange 310 to slide. The second connecting flange 310 is slidably connected to the threaded structure.

[0040] Example 3

[0041] This embodiment is the third embodiment of a multi-layer composite sound-absorbing plastic pipe. This embodiment is similar to Embodiment 1, except that, as Figure 3 As shown, the placement block 420 is provided with a groove 421 for placing the first muffler 100 or the second muffler 200. The groove 421 is provided so that the first muffler 100 and the second muffler 200 can be placed in the groove 421, which can provide good support for the first muffler 100 and the second muffler 200.

[0042] like Figure 4As shown, the lifting assembly 410 includes a lifting box 411, a screw 412, a moving block 413, a lifting plate 414, a sliding rod, a first lifting rod 415, and a second lifting rod 416. The screw 412 is rotatably connected to the lifting box 411, the moving block 413 is threadedly connected to the screw 412, the moving block 413 is slidably connected to the lifting box 411, the lifting plate 414 is slidably connected to the lifting box 411, the sliding rod is slidably connected to the lifting plate 414, the two ends of the first lifting rod 415 are rotatably connected to the moving block 413 and the lifting plate 414 respectively, the two ends of the second lifting rod 416 are rotatably connected to the lifting box 411 and the sliding rod respectively, the first lifting rod 415 and the second lifting rod 416 are hinged, and the placement block 420 is disposed on the lifting plate 414. Rotating the screw 412 causes the moving block 413 to move, and the first lifting rod 415 and the second lifting rod 416 rotate, causing the lifting plate 414 to slide inside the lifting box 411, thereby causing the lifting plate 414 to rise and fall.

[0043] Example 4

[0044] This embodiment is the fourth embodiment of a multi-layer composite sound-absorbing plastic pipe. This embodiment is similar to Embodiment 1, except that, as... Figure 5 As shown, both the first silencer pipe 100 and the second silencer pipe 200 also include an asbestos pipe 130, which is located between the threaded silencer pipe 120 and the drain pipe 110. The asbestos pipe 130 further reduces noise.

[0045] Both the first silencer pipe 100 and the second silencer pipe 200 also include a reinforcing pipe 140, which is located between the asbestos pipe 130 and the drain pipe 110. For example... Figure 5 As shown, the first silencer pipe 100 and the second silencer pipe 200, from the inside out, are a drain pipe 110, a reinforcing pipe 140, an asbestos pipe 130, and a threaded silencer pipe 120, respectively. By setting the reinforcing pipe 140, the strength of the drain pipe 110 is enhanced, while the threaded silencer pipe 120 and the drain pipe 110 are isolated to prevent water leakage from seeping outward when the drain pipe 110 has a hidden crack.
