Description
Technical field
This utility model is related to insulating tube technical field, more particularly, to a kind of hydraulic pressure foaming platform.
Background technology
Prefabricated direct-buried heat insulation pipe is mainly used in district heating outer net pipeline, with the popularization to central heating for the country, its
Consumption is increasing, and range is also more and more wider.Prefabricated direct-buried thermal insulation pipe road has waterproof, antiseptic property is good, save throwing
Money, shortening construction period, the low plurality of advantages of maintenance cost.And the prefabricated direct-buried pipe using at present is by steel pipe, support, insulation
Layer, outer protection tube composition, typically select seamless pipe spiral welded and straight-seam pipes according to design and customer requirement.
, after advanced impeller blasting PROCESS FOR TREATMENT, steel pipe derusting grade is up to gb8923-1988 standard for steel tube surface
In sa2 level, surface roughness is up to r=12.5 micron in gb6060.5-88 standard.Heat-insulation layer, with high pressure foaming machine in steel
In the cavity that pipe is formed between the outer jacket, disposable injection RPUF stock solution forms.It is commonly called as " tube-in-tube
Foam process ".Its effect one is insulation, and two is waterproof, and three is to support heat supply network deadweight.When input media temperature is: -50 DEG C -
When 120 DEG C, do heat-insulation layer from rigid polyurethane foams；When pumped (conveying) medium temperature is: when 50 DEG C -150 DEG C, choosing
Do heat-insulation layer with hard polyurethane base uric acid fat foam plasticss.Protective layer, the black plastic tubing of prefabricated certain wall thickness, through corona
Standby after PROCESS FOR TREATMENT.Its effect one is that protection heat-insulation layer exempts from machinery hard thing destruction, and two is anti-corrosion waterproof.
At present, in the utilidor course of processing, an important step is had to be exactly the manufacture to heat-insulation layer, existing considerable part
Pipe insulating layer adopt polyurethane material, the manufacture of this part will be sent out using implementing polyurethane between pipeline and outer protection tube
Bubble operation.Steel tube fixed knot is a part for pipeline, has flange in the middle of it.In the prior art, foaming platform mainly by
Fixed mount, the closure ring being arranged on fixed mount two ends are constituted, and this closure ring mainly advances by hydraulic jack, and then to insulating steel tube
Blocked, finally polyurethane foam is carried out to pipeline and outer protection tube gap by foaming machine.In prior art closure ring due to
Using a closure ring, the effect of closure ring is will to be sealed between trocar sheath and steel pipe simultaneously, thus can exist at two
Seal point, a seal point is between closure ring and overcoat tube section, and another seal point is between closure ring and outer wall of steel pipe,
Traditional single closure ring is merely able to ensure to be fitted close between closure ring and trocar sheath by the pressure of cylinder, prevents from letting out herein
Dew, and for closure ring and outer wall of steel pipe between then it is difficult to ensure that, unique mode is to try to make internal diameter and the steel pipe of closure ring
External diameter remain close to, as far as possible shorten closure ring and steel pipe between gap, but still have larger amount of polyurethane and expose,
Polyurethane is led to waste more.
