Description
Technical field
The utility model is related to tubing technical field, especially a kind of novel PVC-U drainpipes.
Background technology
PVC-U pipelines are that suitable stabilizer, lubrication is added using Sanitary PVC (PVC) resin as primary raw material
Agent, filler, toner etc. pass through cooling, solidification, sizing, inspection through plastic extruder extrusion molding and injection molding machine injection molding
The processes such as test, pack to complete the production of tubing, pipe fitting.Physical and chemical performance is excellent, resistant to chemical etching, and shock strength is high, fluid resistance
Power is small, relatively with bore cast iron pipe flow improve 30%, ageing-resistant, service life is long, service life be not less than 50 years, be building to
The ideal material of draining.
And existing PVC-U pipelines have that crushing resistance is not strong and not corrosion-resistant, therefore study a kind of novel PVC-U
Drainpipe is to overcome the problems, such as that these are actually important.
Utility model content
The purpose of this utility model is to provide a kind of novel PVC-U drainpipes, the drainpipe is by being arranged unique add
Strengthening tendons structure is to improve the crushing resistance of water pipe entirety, and in addition the water pipe is also equipped with corrosion resistant characteristic.
To achieve the above object, the technical solution adopted in the utility model is as follows：A kind of novel PVC-U drainpipes, including
PVC-U internal layers and PVC-U outer layers are provided with reinforcing rib structure between the PVC-U internal layers and PVC-U outer layers；Described adds
Strengthening tendons structure is composed of reinforcing rib body under reinforcing rib body on several and several；In the lower part of the upper reinforcing rib body
The heart is provided with lower clamping groove；The top of the lower reinforcing rib body is respectively arranged with upper clamping close to the position of left and right side
Groove is provided with support column between two upper clamping grooves；
The lower reinforcing rib body arrays from left to right setting, and the lower part of the upper reinforcing rib body is clamped on respectively
In two mutually close upper clamping grooves of two neighboring lower reinforcing rib body, the mutually close upper lateral part of two neighboring lower reinforcing rib body
It is clamped in the same lower clamping groove；The either flush of the top surface of the support column and upper reinforcing rib body.
Preferably, it is provided with refractory layer on the inner surface of the PVC-U internal layers.
Preferably, it is provided with anti-corrosion layer on the outer surface of the PVC-U outer layers.
Preferably, it is provided with wearing layer on the outside of the anti-corrosion layer.
The beneficial effects of the utility model：
1, reinforcing rib structure is arranged between PVC-U internal layers and PVC-U outer layers, and one is played when water pipe is by external compression
The effect of a support, to prevent pipe burst；Since reinforcing rib structure is by reinforcing rib body on several and several lower reinforcing rib bodies
It is composed, and mutual clamping setting, anti-antipriming pipe are sent out when by axial tension up and down for upper reinforcing rib body and lower reinforcing rib body
The case where raw fracture.
2, it is provided with refractory layer on the inner surface of PVC-U internal layers, avoids the feelings that water pipe deforms because temperature is excessively high
Condition.
3, it is provided with anti-corrosion layer on the outer surface of PVC-U outer layers, it is therefore prevented that water pipe corrodes, and improves service life.
