Description

Technical Field

[0001] The utility model relates to the technical field of plastic steel pipes, in particular to a plastic steel pipe with good sound insulation. Background Art

[0002] Plastic steel pipes are widely used in drainage pipes, water supply pipes, fire water pipes, heat network return pipes, etc. required in municipalities and communities. Because they are close to domestic water and close to people in living areas, the sound insulation of plastic steel pipes needs to be paid attention to.

[0003] Some of the existing plastic-steel pipes have sound insulation structures, while others are for direct use. However, even for plastic-steel pipes with sound insulation structures, the sound insulation structure and the pipe body are integrated and fixedly connected, which is not conducive to later removal, replacement and maintenance by personnel. Tools such as cutting machines are required, which makes the later maintenance cost relatively high.

[0004] The existing plastic steel pipes suitable for municipal and community use have the following disadvantages: the sound insulation structure and the pipe body are integrated and fixedly connected, which is not conducive to the later removal, replacement and maintenance of personnel, and requires the use of tools such as cutting machines, which makes the later maintenance cost high. Therefore, we propose a plastic steel pipe with good sound insulation. Summary of the invention

[0005] The main purpose of the utility model is to provide a plastic steel pipe with good sound insulation, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A plastic-steel pipe with good sound insulation comprises a plastic-steel core pipe and a sound insulation composite sleeve, wherein clamping blocks are respectively arranged on both sides of the plastic-steel core pipe, and clamping grooves corresponding to the clamping blocks are respectively opened on both sides of the sound insulation composite sleeve, and the sound insulation composite sleeve comprises a first semicircular sleeve and a second semicircular sleeve, wherein the first semicircular sleeve and the second semicircular sleeve are composed of a PVC anti-corrosion surface layer, a glass fiber sound insulation layer and a honeycomb foam sound absorption layer.

[0008] Furthermore, the glass fiber sound insulation layer is located between the PVC anti-corrosion surface layer and the honeycomb foam sound absorption layer, and the PVC anti-corrosion surface layer, the glass fiber sound insulation layer and the honeycomb foam sound absorption layer are subjected to high-temperature pressing treatment by a high-temperature heat sealing machine.

[0009] Furthermore, the end surfaces on both sides of the first semicircular sleeve and the second semicircular sleeve are respectively provided with a notch and a protrusion.

[0010] Furthermore, corresponding mounting ears are respectively arranged on the outer sides of the first semicircular sleeve and the second semicircular sleeve, and the mounting ears of the first semicircular sleeve and the second semicircular sleeve are connected by bolts.

[0011] Compared with the prior art, the utility model has the following beneficial effects: through the assembly consisting of a plastic-steel core tube and a sound-proof composite sleeve, a set of plastic-steel pipe assemblies with good thermal insulation and high sound insulation is provided for applications such as drainage pipes, water supply pipes, fire water pipes, heat network return pipes, and floor drainage pipes required in municipalities and communities, so as to effectively solve the water flow noise pollution caused by water source transportation in municipalities and communities to people in living areas. The utility model is convenient to assemble, and easy to disassemble, replace, and maintain. The clamping limit of the clamping block and the clamping groove can effectively avoid the problem of self-spin between the plastic-steel core tube and the sound-proof composite sleeve during pipeline vibration, and solves the problem that the existing plastic-steel pipe sound insulation structure used for drainage pipes, water supply pipes, fire water pipes, heat network return pipes, etc. required in municipalities and communities cannot be separated, disassembled, replaced, and maintained in the later stage.

[0020] like Figure 1-6As shown, a plastic-steel pipe with good sound insulation comprises a plastic-steel core pipe 1 and a sound insulation composite sleeve 2, blocks 5 are respectively arranged on both sides of the plastic-steel core pipe 1, and slots 6 corresponding to the blocks 5 are respectively opened on both sides of the sound insulation composite sleeve 2, the sound insulation composite sleeve 2 comprises a first semicircular sleeve 3 and a second semicircular sleeve 4, the first semicircular sleeve 3 and the second semicircular sleeve 4 are composed of a PVC anti-corrosion surface layer 10, a glass fiber sound insulation layer 11 and a honeycomb hole foam sound absorption layer 12, the glass fiber sound insulation layer 11 is located between the PVC anti-corrosion surface layer 10 and the honeycomb hole foam sound absorption layer 12, the PVC anti-corrosion surface layer 10, the glass fiber sound insulation layer 11 and the honeycomb hole foam sound absorption layer 12 are subjected to high-temperature pressing treatment by a high-temperature heat sealing machine, the first semicircular sleeve 3 and the second semicircular sleeve 4 are respectively provided with corresponding mounting ears 7 on both sides outside, and the mounting ears 7 of the first semicircular sleeve 3 and the second semicircular sleeve 4 are connected by bolts.

[0021] The end surfaces of both sides of the first semicircular sleeve 3 and the second semicircular sleeve 4 are respectively provided with a notch 8 and a protrusion 9; the notch 8 and the protrusion 9 are more conducive to the covering and biting between the first semicircular sleeve 3 and the second semicircular sleeve 4.

[0022] It should be noted that the utility model is a plastic-steel pipe with good sound insulation. When working, the personnel select the required length of the plastic-steel core pipe 1 and assemble it with the pipeline of the construction site, and then cut the required length of the sound insulation composite sleeve 2 to cover the outer periphery of the plastic-steel core pipe 1. When covering, the first semicircular sleeve 3 and the second semicircular sleeve 4 are respectively covered on both sides of the plastic-steel core pipe 1, and the card slot 6 is successively clamped on the card block 5 to ensure that the vibration in the later use of the pipeline will not cause the sound insulation layer to displace and spin. Based on the arrangement of the honeycomb foam sound-absorbing layer 12 and the glass fiber sound insulation layer 11, the noise transmitted by the plastic-steel core pipe 1 can be effectively absorbed and soundproofed to reduce the water flow noise pollution caused by water source transportation to people in the living area, and by reducing the loss of water source heat energy in the plastic-steel core pipe 1, the water source transportation such as the heat network return pipe is made more stable.
