Description

Technical Field

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

[0002] Pipelines are used to transport fluids such as gas and liquid. During the transportation process, large noise will be generated due to the friction between the fluid and the pipeline. At present, in order to reduce the impact of noise on production and life, a layer of sound-absorbing pads is usually wrapped on the outside of the pipeline. Conventional sound-absorbing pads are prone to aging after long-term service, and the sound insulation effect is also poor. At the same time, when fixing the sound-absorbing pads, tape is usually used. When the sound-absorbing pads are replaced, the aged sound-absorbing pads are broken, which brings inconvenience to the replacement operation. Utility Model Content

[0003] The utility model provides a pipeline silencer strip to solve the above-mentioned deficiencies in the prior art, improve the sound insulation effect, and has strong practicability.

[0004] In order to achieve the purpose of this utility model, the following technologies are proposed:

[0005] A pipe silencer strip is wrapped around the outer circumference of the pipe in a spiral shape and has a long strip structure. The silencer strip includes a hollow tube wrapped around the outer circumference of the pipe in a spiral shape. The hollow tube has a rectangular structure. A pair of L-shaped plates are formed on one side of the hollow tube, and a pair of L-shaped grooves are opened on the other side of the hollow tube. When the hollow tube is wrapped around the outer circumference of the pipe, the L-shaped plate is clamped in the L-shaped groove. The two ends of the hollow tube are respectively penetrated by inner blocks, and the outer end of the inner block is provided with an end cover, and the end cover is provided with a pipe head. The inner block and the end cover are provided with holes through the hole, which are connected to the pipe head, and the outer end of the pipe head is screwed with an end plug. The wound hollow tubes can be connected together by the L-shaped plates and L-shaped grooves, so as to avoid the phenomenon of looseness. Of course, the sound insulation effect is improved by wrapping the pipe in all directions. The hollow tube is provided with a liquid with a high viscosity to improve the noise reduction effect, and of course, the propagation of noise can also be hindered by vacuuming.

[0006] Furthermore, the hollow tube is filled with liquid, and the liquid here can be a liquid with a relatively high viscosity. Such liquid can reduce the propagation energy of noise, thereby achieving a noise reduction effect.

[0007] Furthermore, a plurality of grooves are provided on the outer wall of the inner block. When the inner block is fixed on the hollow tube, the provision of the grooves expands the bonding area between the adhesive glue and the hollow tube, thereby improving the bonding effect.

[0008] The advantages of the above technical solution are:

[0009] The utility model can improve the noise reduction and sound insulation effect of the pipeline and can also ensure the stability after winding. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0015] like Figure 1~Figure 4 As shown, a pipe silencer strip is wrapped around the outer periphery of the pipe 1 in a spiral shape and has a long strip structure. The silencer strip includes a hollow tube 2 that is spirally wound around the outer periphery of the pipe 1, and the hollow tube 2 is filled with liquid. The hollow tube 2 is a rectangular structure, and a pair of L-shaped plates 20 are formed on one side of the hollow tube 2, and a pair of L-shaped grooves 21 are opened on the other side of the hollow tube 2. When the hollow tube 2 is wrapped around the outer periphery of the pipe 1, the L-shaped plates 20 are clamped in the L-shaped grooves 21. The two ends of the hollow tube 2 are respectively penetrated by inner blocks 23, and a plurality of grooves 24 are opened on the outer wall of the inner block 23. An end cover 25 is provided at the outer end of the inner block 23, and a pipe head 26 is provided on the end cover 25. A hole 28 is opened through the inner block 23 and the end cover 25, and the hole 28 is connected to the pipe head 26. An end plug 27 is screwed on the outer end of the pipe head 26.

[0016] When operating this embodiment, the operator first inserts the inner block 23 into one end of the hollow tube 2, and fixes the inner block 23 to one end of the hollow tube 2 by gluing, and fixes the end plug 27 to the tube head 26. Then the hollow tube 2 is wound on the pipe 1. During the winding process, the L-shaped plate 20 needs to be clamped in the L-shaped groove 21 to ensure that the hollow tube 2 is seamlessly wrapped on the outside of the pipe 1. After the winding is completed, the inner block 23 is fixed on the other end of the hollow tube 2, and then the liquid is injected into the hollow tube 2. When injecting the liquid, the previous end plug 27 can be removed first, and after the liquid is filled, another end plug 27 is installed on the outer end of the tube head 26. When the fluid passes through the pipe 1, the noise generated needs to pass through the hollow tube 2 and the liquid in the hollow tube 2, thereby reducing the propagation energy of the noise, thereby achieving a noise reduction effect.

[0017] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Obviously, those skilled in the art can make various changes and modifications to the utility model without departing from the spirit and scope of the utility model. Thus, if these modifications and variations of the utility model fall within the scope of the claims of the utility model and their equivalents, the utility model is also intended to include these modifications and variations.
