Abstract
The utility model is related to a kind of noise reduction fire-type drainpipe, which includes successively from the inside to the outside nano-antibacterial layer, PVC internal layers, polyurethane insulation coating, PVC outer layers, and the center of drainpipe is provided with solid inner tube along water pipe axial direction；Spiral welding is connected to helical form guide vane in the solid inner tube, is welded to connect with nano-antibacterial layer inner wall outside the spiral of the guide vane；It is stained with fireprotection layer on the outside of PVC outer layers, the setting of helical form guide vane so that guide vane forms spiral stream guidance channel with nano-antibacterial layer inner wall, and flow is flowed out along spiral stream guidance channel, the sound for reducing flow impact tube wall achievees the effect that reduce noise.Contact surface between the PVC outer layers and fireprotection layer is mutually matched male and fomale(M＆F), further increases the structural stability that PVC outer layers 4 and fireprotection layer 8 coordinate.
Description
Technical field
The utility model is related to tubing technical field, especially a kind of noise reduction fire-type drainpipe.
Background technology
Existing drainpipe is using polyvinyl chloride (PVC) resin as primary raw material is extruded or a kind of plastics of injection molding
Pipe fitting.PVC pipe has many advantages, such as light-weight, corrosion-resistant, small flow resistance, energy saving, the fast, low cost of installation, by
Application is widelyd popularize, remarkable benefit is widely used in cities and towns tap water water delivery water supply project, Discussion on architecture water supply project, industrial and mineral
Enterprise's water supply project, buried fire fighting supply engineering, irrigation and water conservancy burial conveyance of water irrigation engineering, gardens garderning green water supply project, aquatic products
Aquaculture water supply and drainage engineering etc., and obtain good economic benefit and social benefit.
But the drainage noise of existing ordinary draining pipe is higher than traditional cast iron pipe, and the soundproof effect of cast-in-situ floor compared with
Difference, user can be clearly felt that the noise of drainage pipeline, are unfavorable for people's use, need to change existing PVC drain pipe
Into.In addition, existing drainpipe fire protecting performance is poor.
Utility model content
The purpose of this utility model is to provide a kind of noise reduction fire-type drainpipe, which can effectively reduce and make an uproar
Sound, and there is stronger fire protecting performance.
To achieve the above object, the technical solution adopted in the utility model is as follows：A kind of noise reduction fire-type drainpipe, the row
Water pipe includes nano-antibacterial layer, PVC internal layers, polyurethane insulation coating, PVC outer layers, the center Yan Shui of drainpipe successively from the inside to the outside
Pipe axial direction is provided with solid inner tube；Spiral welding is connected to helical form guide vane, the water conservancy diversion in the solid inner tube
It is welded to connect with nano-antibacterial layer inner wall outside the spiral of blade；It is stained with fireprotection layer on the outside of the PVC outer layers, it is described
Contact surface between PVC outer layers and fireprotection layer is mutually matched male and fomale(M＆F).
Preferably, one layer of anti-biotic material layer is coated on the outer tube wall of the solid inner tube.
Preferably, the outer surface of the guide vane is coated with one layer of anti-biotic material layer.
Preferably, it is coated with hard foam layer on the outside of the fireprotection layer.
Preferably, the contact surface between the PVC outer layers and fireprotection layer is serrated along the axial direction of tubing.
The beneficial effects of the utility model：
1, the setting of helical form guide vane so that guide vane forms spiral stream guidance channel with nano-antibacterial layer inner wall,
Flow is flowed out along spiral stream guidance channel, reduces the sound of flow impact tube wall, achievees the effect that reduce noise.
2, the setting of nano-antibacterial layer plays the role of sterilization to flow.
3, insulation effect is played in the setting of polyurethane insulation coating.
4, protection is played the role of in the setting of hard foam layer.
5, the contact surface between PVC outer layers and fireprotection layer uses the axial direction along tubing to cooperate in the male and fomale(M＆F) of sawtooth,
So that along the axial of tubing opposite sliding will not occur for PVC outer layers and fireprotection layer, ensure the stability of pipe structure.In addition, such as
The relatively existing smooth arc contact surface of the concave-convex contact surface in sawtooth of fruit internal layer expanded by heating, the utility model can be born
The expansion rate of bigger.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model.
In figure：1- nano-antibacterial layers；2-PVC internal layers；3- polyurethane insulation coatings；4-PVC outer layers；The solid inner tubes of 5-；6- is led

Specific implementation mode
The utility model is described in detail with reference to specific embodiments and the drawings.
Embodiment 1
As shown in Figure 1, a kind of noise reduction fire-type drainpipe, the drainpipe include successively from the inside to the outside nano-antibacterial layer 1,
The center of PVC internal layers 2, polyurethane insulation coating 3, PVC outer layers 4, drainpipe is provided with solid inner tube 5 along water pipe axial direction；It is real
Spiral welding is connected to helical form guide vane 6 on intracardiac pipe 5, connects with the welding of 1 inner wall of nano-antibacterial layer outside the spiral of guide vane 6
It connects, guide vane 6 forms spiral stream guidance channel with 1 inner wall of nano-antibacterial layer so that flow is flowed out along spiral stream guidance channel, is subtracted
The sound for having lacked flow impact tube wall achievees the effect that reduce noise.The outside of PVC outer layers 4 is stained with fireprotection layer 8, described
Contact surface between PVC outer layers 4 and fireprotection layer 8 is serrated along the axial direction of tubing, further increases PVC outer layers 4 and fireprotection layer 8
The structural stability of cooperation.
One layer of anti-biotic material layer is coated on the outer tube wall of solid inner tube 5；The outer surface of guide vane 6 is coated with one layer and resists
Bacterium material layer, is furthermore achieved biocidal efficacies.
The outside of fireprotection layer 8 is coated with hard foam layer 7, plays protective action.
