Abstract
The plastic-sheathed steel heat-insulation pipe expansion joint consists of a steel pipe, a heat-insulation layer, an outer sheath and a rubber expansion pipe sleeve, wherein the heat-insulation layer is arranged between the steel pipe and the outer sheath, the rubber expansion pipe sleeve is coated on the surface of the outer sheath, the rubber expansion pipe sleeve has a corrugated structure, a waterproof adhesive tape is filled between the outer sheath and the rubber expansion pipe sleeve, and a plurality of anchoring ribs symmetrically penetrate through the rubber expansion pipe sleeve and are inserted into the outer sheath. The utility model discloses set up corrugated rubber telescopic pipe cover and waterproof stripe on steel pipe oversheath surface, rubber telescopic pipe cover and waterproof stripe leave flexible volume for elastic material, can stretch out and draw back along with the steel pipe main part, prevent to tear, the utility model discloses the impact resistance and the intensity of telescopic joint itself have been improved greatly, have compact structure, reasonable in design and the effectual advantage that keeps warm.
Description
Technical Field
The utility model relates to a heat preservation pipeline accessory, concretely relates to mould cover steel insulating tube telescopic joint.
Background
At present, in the steam direct-buried conveying technology of the domestic thermoelectric industry, the steam direct-buried pipeline expansion joint is in a structural form that one or a pair of horn-shaped supports are welded between a working pipe and an outer sleeve pipe to relatively fix an inner pipe and an outer pipe. This structure has the following disadvantages: the heat insulation gap is large, the heat insulation effect is poor, and the heat insulation layer is generally thick; the fixing bracket is directly welded between the inner pipe and the outer pipe to form a heat bridge, so that heat is easily radiated from the heat bridge.
Disclosure of Invention
The utility model provides a plastic sleeve steel insulating tube expansion joint to solve the poor problem that gives off with the heat of the heat preservation effect that prior art exists.
The utility model provides a technical scheme that its technical problem adopted is:
a plastic-sheathed steel heat-insulation pipe expansion joint comprises a steel pipe, a heat-insulation layer, an outer sheath and a rubber expansion pipe sleeve, wherein the heat-insulation layer is arranged between the steel pipe and the outer sheath, the rubber expansion pipe sleeve is coated on the surface of the outer sheath, the rubber expansion pipe sleeve is of a corrugated structure, a waterproof adhesive tape is filled between the outer sheath and the rubber expansion pipe sleeve, and a plurality of anchoring ribs symmetrically penetrate through the rubber expansion pipe sleeve and are inserted into the outer sheath.
The utility model discloses set up corrugated rubber telescopic pipe cover and waterproof stripe on steel pipe oversheath surface, rubber telescopic pipe cover and waterproof stripe leave flexible volume for elastic material, can stretch out and draw back along with the steel pipe main part, prevent to tear, the utility model discloses the impact resistance and the intensity of telescopic joint itself have been improved greatly, have compact structure, reasonable in design and the effectual advantage that keeps warm.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention.
In the figure, a steel pipe 1, a heat-insulating layer 2, an outer sheath 3, a rubber telescopic pipe sleeve 4, a waterproof adhesive tape 5 and an anchoring rib 6 are arranged.
Detailed Description
As shown in the figure, the plastic-sheathed steel heat-insulation pipe expansion joint comprises a steel pipe 1, a heat-insulation layer 2, an outer sheath 3 and a rubber telescopic pipe sleeve 4, wherein the heat-insulation layer 2 is arranged between the steel pipe 1 and the outer sheath 3, the rubber telescopic pipe sleeve 4 is coated on the surface of the outer sheath 3, the rubber telescopic pipe sleeve 4 is of a corrugated structure, a waterproof adhesive tape 5 is filled between the outer sheath 3 and the rubber telescopic pipe sleeve 4, and a plurality of anchoring ribs 6 symmetrically penetrate through the rubber telescopic pipe sleeve 4 and are inserted into the outer sheath 3.
The utility model discloses set up corrugated rubber telescopic pipe cover and waterproof stripe on steel pipe oversheath surface, rubber telescopic pipe cover and waterproof stripe leave flexible volume for elastic material, can stretch out and draw back along with the steel pipe main part, prevent to tear, the utility model discloses the impact resistance and the intensity of telescopic joint itself have been improved greatly, have compact structure, reasonable in design and the effectual advantage that keeps warm.
