TECHNICAL FIELD

[0001] The utility model relates to pipeline sound attenuation technical field, concretely relates to a sound attenuation device of spring water direct drinking engineering construction. BACKGROUND

[0002] In the early stage of spring water direct drinking engineering construction, it is stipulated that the pipeline or the underground channel should be used for conveying raw water in the city construction, and the pump house spring water is introduced into the user's home. For the pipeline laying of the existing building, the pre-buried pipe construction cannot be operated to form effective shielding, so the water conveying pipeline is often exposed outside. When the pipeline (especially the 90° elbow pipe) has spring water flowing through it, a loud noise is generated, which seriously interferes with the life of the residents and produces adverse effects. CONTENT OF UTILITY MODEL

[0003] The utility model is specifically designed for the above-mentioned problems, and a sound attenuation device of spring water direct drinking engineering construction is designed to reduce the impact of water flow on the water conveying pipeline and enhance the sound insulation effect to reduce the life noise of the residents.

[0004] To achieve the above-mentioned purpose, the utility model provides a sound attenuation device of spring water direct drinking engineering construction, which comprises a water inlet pipe, a water outlet pipe, a first water conveying pipe, a spiral guide layer, a second water conveying pipe and a sound attenuation layer. The first water conveying pipe and the second water conveying pipe are both 90° elbow pipes. The first water conveying pipe is inserted into the second water conveying pipe, and a plurality of sound attenuation holes are formed in the first water conveying pipe along the water flow impact direction. The spiral guide layer is fixedly arranged between the first water conveying pipe and the second water conveying pipe, and the sound attenuation layer is detachably arranged outside the second water conveying pipe. The water inlet pipe covers the water inlet of the first water conveying pipe, and the water outlet pipe is connected to the water outlet of the second water conveying pipe.

[0005] Preferably, the sound attenuation layer comprises sound insulation cotton and fireproof cloth. The sound insulation cotton is wrapped outside the outer wall of the second water conveying pipe, and the fireproof cloth is wrapped outside the sound insulation cotton.

[0006] Preferably, the fireproof cloth is made of aluminum foil glass fiber cloth or ceramic fiber cotton.

[0007] Preferably, the sound attenuation layer is fixedly connected with a hook-and-loop fastener on both sides.

[0008] In summary, the utility model has the following advantages and beneficial technical effects:

[0009] 1. The utility model opens sound attenuation holes in the first water conveying pipe, so that the fluid releases part of the pressure through the small holes, reduces the generation of fluid fluctuation and acoustic effect, and at the same time, the sound attenuation holes also have a buffering effect, so that part of the spring water directly passes through the sound attenuation holes, reducing the impact on the water conveying pipeline. In addition, the spring water flowing through the spiral guide layer of the outer arm of the first water conveying pipe reduces the flow rate, fundamentally reduces the noise and guarantees the normal life of the residents.

[0010] 2. The setting of the sound-absorbing layer uses special materials and structural design to prevent the flow of air to reduce the spread of noise, further absorbs and isolates noise, and reduces the impact of noise on the living environment of residents. In addition, the sound-absorbing layer also has good heat preservation function, effectively prevents heat transfer, and keeps the temperature in the pipe stable. The main function of the fireproof layer is to provide fire protection for the water pipeline, which can effectively slow down the fire and prevent the spread of fire, thereby reducing the risk of personnel casualties or property losses.

[0011] 3. The velcro is used to fix the sound-absorbing layer, which is simple in use principle, convenient to disassemble and assemble, saves the time of replacing the sound-absorbing layer, and improves the maintenance efficiency. BRIEF DESCRIPTION OF DRAWINGS
