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 compression-resistant fire
Type PVC-U tubing 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 compression-resistant fire type PVC-U tubing, the drainpipe is unique by being arranged
Reinforcing rib structure to improve the crushing resistance of water pipe entirety, 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 compression-resistant fire type PVC-U tubing,
Including PVC-U internal layers and PVC-U outer layers, reinforcing rib structure is provided between the PVC-U internal layers and PVC-U outer layers；It is described
Reinforcing rib structure be composed of reinforcing rib body on several and several lower reinforcing rib bodies；Under the upper reinforcing rib body
Portion is provided centrally with lower clamping groove；The top of the lower reinforcing rib body is respectively arranged with close to the position of left and right side
Clamping 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；
Fireprotection layer, the contact surface between the PVC-U outer layers and fireprotection layer are stained on the outside of the PVC-U outer layers
For mutually matched male and fomale(M＆F).
Preferably, it is provided with refractory layer on the inner surface of the PVC-U internal layers.
Preferably, the contact surface between the PVC-U outer layers and fireprotection layer is serrated along the axial direction of tubing.
Preferably, it is provided with anti-corrosion layer on the outside of the fireprotection 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.
4, it is in the male and fomale(M＆F) phase interworking of sawtooth that the contact surface between PVC-U outer layers and fireprotection layer, which uses the axial direction along tubing,
It closes so that along the axial of tubing opposite sliding will not occur for PVC-U outer layers and fireprotection layer, ensure the stability of pipe structure.This
Outside, if internal layer expanded by heating, the relatively existing smooth arc contact surface of the concave-convex contact surface in sawtooth of the utility model can
To bear the expansion rate of bigger.
