Description

Technical Field

[0001] The utility model belongs to the technical field of noise reduction pipelines, and in particular relates to a noise reduction water delivery pipeline. Background Art

[0002] In various water pipelines, due to the vibration caused by the impact of water flow, there is generally a lot of noise around the water pipelines, which has a certain impact on people's lives. At present, the main method of reducing noise is to wrap the outside of the pipeline with a sound insulation layer, but this method consumes a lot of sound insulation pads and is difficult to construct for existing pipelines. On the other hand, the exposed sound insulation layer is easily damaged and has a short service life. Utility Model Content

[0003] In order to solve the deficiencies of the prior art, the utility model provides a noise-reducing water delivery pipeline, which can effectively reduce the noise during water delivery, has a longer service life, and is convenient for modifying existing pipelines.

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

[0005] A noise-reducing water pipeline comprises: a conduit having connecting flanges at both ends, a coaxial ring is provided on the inner wall of the conduit end, the ring is arranged to swing back and forth around the axis, an elastic member is provided between the circumferential position of the ring and the conduit to adapt to the reciprocating swing of the ring, the inner wall of the ring is provided with a guide plate extending toward the middle of the conduit, and the guide plate is inclined relative to the axis of the conduit on the normal projection of the conduit.

[0006] The beneficial effects of the utility model are: by reducing the impact of water flow on the inner wall of the conduit, the noise generation can be effectively reduced, and the service life is longer, while facilitating the modification of existing pipelines.

[0012] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0013] like Figure 1 , Figure 2 As shown, a noise reduction water pipeline comprises: a conduit 1, both ends of which have connecting flanges to facilitate overall installation and convenient modification of existing pipelines, a circular ring 2 is coaxially arranged on the inner wall of the end of the conduit 1, and the circular ring 2 is arranged to swing back and forth around the axis, an elastic member 3 is arranged between the circumferential position of the circular ring 2 and the conduit 1 to adapt to the reciprocating swing of the circular ring 2, and the inner wall of the circular ring 2 is provided with a guide plate 21 extending toward the middle of the conduit 1, and the guide plate 21 is inclined relative to the axis of the conduit 1 on the normal projection of the conduit 1. When water flows through the guide plate 21, the guide plate 21 will guide the flow direction of the water flow near the inner wall of the conduit 1, so that the water flow near the inner wall of the conduit 1 is transported forward in a spiral manner, thereby reducing the impact force of the water flow near the inner wall of the conduit 1, thereby reducing noise, while the water flow in the middle of the conduit 1 will not be affected by the guide plate 21, so the impact on the flow velocity of the water flow in the middle of the conduit 1 can be reduced; and the purpose of setting the elastic member 3 is that when the guide plate 21 encounters water flows with different flow rates, it adapts to the changes in the water flow velocity by swinging back and forth around the conduit 1, thereby reducing the damage to the guide plate 21 caused by the impact of the water flow, including deformation damage or breakage damage.

[0014] Preferably, Figure 2 , Figure 3 As shown, the inner wall of the end of the catheter 1 is coaxially provided with a bottom hole 11 of a circular structure, the top surface of the bottom hole 11 is coaxially provided with a countersunk hole 12 of a circular structure, and the inner diameter of the countersunk hole 12 is larger than the inner diameter of the bottom hole 11, a ring 2 is arranged in the bottom hole 11, and the thickness of the ring 2 is smaller than the distance between the bottom surface of the bottom hole 11 and the bottom surface of the countersunk hole 12, and a pressing ring 4 is arranged in the countersunk hole 12 for limiting the axial displacement of the ring 2 to prevent the ring 2 from falling out of the catheter 1. More specifically, the pressing ring 4 is connected to the inner wall of the catheter 1 by screws.

[0015] Preferably, Figure 3 As shown, the inner diameters of the pressure ring 4 and the circular ring 2 are the same as the inner diameter of the conduit 1 to ensure the flatness of the inner wall of the water delivery pipeline.

[0016] Preferably, Figure 2 , Figure 3As shown, an arc-shaped groove is provided on the side wall of the bottom hole 11, and a protrusion 22 is provided on the outer wall of the ring 2. The protrusion 22 is located in the arc-shaped groove, and elastic members 3 are provided on both sides of the arc-shaped groove corresponding to the protrusion 22 in the circumferential direction, so as to enable the ring 2 to swing back and forth around the circle. The arc-shaped groove is connected to the bottom surface of the countersunk hole 12 to facilitate processing and setting of the protrusion 22 and the elastic member 3.

[0017] Preferably, Figure 1 As shown, the guide plate 21 is located inside the end surface of the conduit 1, so that the conduit 1 can be smoothly inserted between two existing water pipes to prevent the guide plate 21 from being damaged during installation.

[0018] The above is only a preferred embodiment of the utility model, and does not mean that it is the only one or limit the utility model. Those skilled in the art should understand that various changes or equivalent replacements made to the utility model without departing from the scope of the utility model are within the scope of protection of the utility model.
