Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of building drainage pipes, and particularly relates to a building drainage noise reduction pipe. Background Art
[0002] Building drainage noise reduction pipes are pipe systems specially used to reduce the noise generated during the drainage process. This type of pipe usually uses special materials and structures to achieve the effect of reducing noise. Polypropylene material has good temperature resistance, chemical corrosion resistance and impact resistance. At the same time, by adding special sound-absorbing materials, the density and microstructure of the pipe can be adjusted to effectively absorb and prevent the transmission of audible sound waves to achieve noise reduction effects. This material is often used to make silent drainage pipes such as HTPP and HDPE.
[0003] The patent with application number 202420181004.3 discloses a noise reduction device for building drainage pipes. When water flows through the sewer pipe, the water flows downward in a spiral shape and will not generate vibration noise due to the water hitting the pipe wall. When the water flow is large, the first buffer spring and the second buffer spring can offset the noise and resonance caused by the vibration generated by the water impacting the pipe wall; combined with the above application, and in connection with the existing noise reduction pipes, the existing pipes usually achieve the noise reduction effect by adding special sound-absorbing materials, but during use, if the impact of the water flow in the pipe is large, it will still generate excessive noise, thereby affecting the practicality of the device. For this reason, we propose a building drainage noise reduction pipe. Utility Model Content
[0004] The purpose of the present utility model is to provide a building drainage noise reduction pipe to solve the problem raised in the above background technology. Compared with the existing noise reduction pipes, the existing pipes usually achieve the noise reduction effect by adding special sound-absorbing materials. However, during use, if the impact force of the water flow in the pipe is large, excessive noise will still be generated, thereby affecting the practicality of the device.
[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a building drainage noise reduction pipe, comprising a pipe body, the pipe body comprising a protective outer pipe and a polypropylene sound insulation inner pipe, the polypropylene sound insulation inner pipe is located on the inner side of the protective outer pipe, a throttling seat is fixedly installed on the inner side of the polypropylene sound insulation inner pipe, a throttling support seat plate is installed on the bottom of the throttling seat on the inner side of the polypropylene sound insulation inner pipe, a lifting slide is provided at the bottom of the throttling support seat plate, a limiting lifting rod is installed through the lifting slide, and a throttling blocking block is fixedly installed on the top of the limiting lifting rod, and a reset spring is installed on the limiting lifting rod between the throttling support seat plate and the throttling blocking block.
[0006] Preferably, a throttling inner flow channel is provided at the bottom of the throttling seat, and the throttling sealing block is in contact with and fitted on the throttling seat through the throttling inner flow channel.
[0007] Preferably, a plurality of through throttling inner flow channels are opened on the surface of the throttling blocking block, and the plurality of throttling inner flow channels are arranged in an array.
[0008] Preferably, the throttling blocking block is limited and lifted by a limiting lifting rod and a lifting slide, and an elastic force is provided by the reset spring.

[0011] Compared with the prior art, the beneficial effects of the present invention are:
[0012] (1) By setting up the pipeline structure with the automatic structural components, when the pipeline in the application is used, multiple throttle seats are equidistantly arranged in the pipeline. If the water pipe is installed vertically, when the water flows through, the water flow passing through the pipeline can be stopped by the throttling effect at each stage, thereby avoiding the large impact force generated when the water flows through the pipeline quickly, reducing the impact force on the pipeline, and at the same time reducing the vibration amplitude of the pipeline, thereby reducing the noise generated by the pipeline;
[0013] (2) At the same time, in order to prevent the water flow from directly impacting the throttle seat when it falls through, a liquid diverter plate with a boss structure is provided on the top of the throttle seat. When the liquid falls on the liquid diverter plate, the liquid can be diverted and dispersed, while reducing the impact force of the liquid when it falls, avoiding the vibration and noise caused by the impact during the falling process, thereby improving the practicality and functionality of the device.

DETAILED DESCRIPTION
[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0018] Example 1
[0019] See also Figure 1 and Figure 2The utility model provides a technical solution: building drainage noise reduction pipes are widely used in places that require a quiet environment, such as residences, offices, hospitals, laboratories, industrial production workshops, etc. In these places, the use of noise reduction pipes can effectively reduce the interference of drainage noise and improve people's quality of life and work. In addition to using noise reduction pipes, measures such as wrapping sound insulation materials and changing the pipe layout can also be taken to further reduce building drainage noise. The building drainage noise reduction pipe includes a pipe body 100. The pipe body 100 includes a protective outer pipe 101 and a polypropylene sound insulation inner pipe 102. The polypropylene sound insulation inner pipe 102 is located on the inner side of the protective outer pipe 101. A throttle seat 200 is fixedly installed on the inner side of the polypropylene sound insulation inner pipe 102. A throttle support seat plate 204 is installed on the inner side of the polypropylene sound insulation inner pipe 102 at the bottom of the throttle seat 200. A lifting slide 206 is provided at the bottom of the throttle support seat plate 204. A limited lifting rod 202 is installed through the lifting slide 206. A throttling block 201 is fixedly installed on the top of the limit lifting rod 202, and a return spring 203 is installed on the limit lifting rod 202 between the throttling support seat plate 204 and the throttling block 201. When the building drainage noise reduction pipe in the application is used, the pipe is fixedly installed vertically. During use, when the water flow in the pipe body 100 falls from a high place, a plurality of throttling seats 200 are arranged at intervals in the pipe body 100, and the water flow falls on the throttling seat 200 and the water flow is When the flow rate is small, it will flow out through the throttling inner flow channel 205 opened on the throttling sealing block 201. The throttling inner flow channel 205 can reduce the falling amount of the water flow, so that the water flow falls slowly, and avoids more water flow directly impacting the pipe body 100. The multiple throttling seats 200 and the throttling sealing block 201 also play a cutting role, avoiding the acceleration of the water flow in the pipe. By reducing the falling amount of the water flow and the acceleration when falling, the noise generated by the vibration generated by the impact when the water flows through is reduced.
[0020] Specifically, a through throttling inner flow channel 205 is provided at the bottom of the throttling seat 200, and the throttling blocking block 201 is in contact with the throttling seat 200 through the throttling inner flow channel 205. A plurality of through throttling inner flow channels 205 are provided on the surface of the throttling blocking block 201, and the plurality of throttling inner flow channels 205 are arranged in an array. The throttling blocking block 201 is limited and lifted by the limiting lifting rod 202 and the lifting slide 206, and an elastic force is provided by the return spring 203. At the same time, a plurality of throttling seats 200 are provided on the inner side of the polypropylene sound insulation inner tube 102, and a throttling blocking block 201 is installed at the bottom of each throttling seat 200. And a throttling support seat plate 204 for installing the throttling sealing block 201. At the same time, multiple throttling seats 200 are installed at equal distances. When a large amount of water flows into the pipe main body 100, the water pressure in the local pipe main body 100 increases, thereby pushing the throttling sealing block 201 open. When the throttling sealing block 201 is pushed open, it is limited and moved by the limiting lifting rod 202, the return spring 203 and the throttling support seat plate 204. The water flows from the opened throttling sealing block 201 and falls between the two throttling seats 200 in the next section. Through the step-by-step buffering effect, the impact force of the water flow when falling can be reduced, thereby better performing noise reduction.
[0021] Specifically, an inverted funnel-shaped liquid diverter plate 300 is provided on the top of the throttle seat 200, and a diverter plate support frame 301 is provided on the bottom of the liquid diverter plate 300. The liquid diverter plate 300 is fixed to the top of the throttle seat 200 through the diverter plate support frame 301. When the water pressure in the pipeline main body 100 is large and it falls directly, a liquid diverter plate 300 with an inclined surface is installed on the top of the throttle seat 200. The liquid diverter plate 300 can guide the water flow that impacts when falling to both sides, which plays a role in dispersing the water flow and reducing the force generated by the contact impact when the water flow falls, thereby better buffering and reducing noise, and further improving the practicality of the pipeline.
