Description
Technical field
The present invention relates to building fields, and in particular to a kind of building water pipe buffer noise reducer and its installation method.
Background technique
In architectural engineering, pipeline through-wall when being laid with bright pipe can be inevitably encountered and occasion excessively, but such pipeline is being constructed
When often in order to which pipeline is fixed, it is just fixed on wall by cement, disassembly when due to pipeline outer wall and wall
Cementing causes pipeline to be difficult to extract, and is unfavorable for the change of later period pipeline；Noise howl can be generated for some feed pipes, when discharging water
It cries, when pipeline and fixed wall, howling can follow wall to be transmitted to entire room, bring sense of discomfort to resident；In water supply
After pipe discharges water when rapid-closure damper faucet, since the water flow in feed pipe is in flow at high speed state, valve is closed in moment
Shi Shuiliu can form hydraulic shock because of its own inertial flow, and feed pipe is caused to shake, and when feed pipe and fixed wall, the shake
Dynamic can directly act on generates knock on wall, can equally generate noise to user and bring sense of discomfort.
Summary of the invention
Based on the above issues, it is an object of that present invention to provide one kind dismantles convenient for pipeline, and separates on pipeline and wall
Through-hole avoids pipeline from contacting the building water pipe buffer noise reducer for generating noise transmission with wall.
In view of the above problems, providing following technical solution: a kind of building water pipe buffer noise reducer, including rubber tube,
The rubber tube wherein turn to outside one end its own outer wall or it is interior turn to its own inner wall and docked with the other end of its own, from
And gasing mezzanine is formed between the outer tube wall and inner tube wall of rubber tube, the gasing mezzanine support the outer tube wall of rubber tube with
Inner tube wall makes rubber tube that original position be made to follow outer pipe wall to grind in into becoming in the rubber tube of outer tube wall in inner tube wall insertion tube material
Barrel, the rubber tube in inner tube wall in situ follow outer pipe wall grind into as outer tube wall so as to circulate back and forth reaching rubber tube
Any position on tubing, the gasing mezzanine is interior to be filled with self-complementing glue.
In above structure, by by rubber tube turn up or varus realize head and the tail dock, the shape between outer tube wall and inner tube wall
At gasing mezzanine, and self-complementing glue is filled in gasing mezzanine, it, will be in rubber sleeve to tubing and by rubber after tubing installation
Cylinder is placed in the through-hole of wall, and being inflated in gasing mezzanine using syringe makes its expansion, is supported, is being extracted between two parties to tubing
It is blocked after syringe needle using self-complementing glue, avoids the occurrence of leakage, using the support of gasing mezzanine by the through-hole on tubing and wall
It is isolated, the hydraulic shock for uttering long and high-pitched sounds and closing valve generation for the generation that either discharges water can be delayed by gasing mezzanine
Punching, avoids uttering long and high-pitched sounds vibration and hydraulic shock vibration is directly transmitted on wall by tubing and amplifies influence resident to noise and make
With impression.
The present invention is further arranged to, and the surfaces externally and internally of the rubber tube is equipped with the expansion opened up along its axial direction
Slot, the expansion slot are several and are uniformly arranged along rubber tube circumferential direction.
In above structure, expansion slot can enable the through-hole on the outer tube wall and wall of rubber tube, and there are certain saturating when contacting
Gas gap, while there are air gaps between inner tube wall and tube surfaces when energy, are finely adjusted, are avoided because of inner tube wall convenient for rotation tubing
Contacting between tube surfaces too closely leads to that adjustment can not be relatively moved between tubing and rubber tube.
The present invention is further arranged to, and the rubber tube is with a thickness of 1mm-10mm.
In above structure, according to different pipe diameters, the rubber tube of different-thickness is selected, rubber barrel thickness and tubing are straight
Diameter is directly proportional.
The present invention is further arranged to, its seaming position is equipped with reinforcing chip at the docking of the rubber tube both ends.
In above structure, reinforcing chip is used to enhance the bonding strength at the docking location of rubber tube both ends.
The present invention is further arranged to, and the reinforcing chip is identical as rubber tube material.
In above structure, same amount of elasticity can be provided, avoids causing to remove because of the two amount of elasticity difference.
The present invention is further arranged to, and is equipped with butting grooves at the docking location of the rubber tube both ends.
In above structure, butting grooves can increase the bond area when docking of rubber tube both ends, viscous after docking to improve
Connect intensity.
