Abstract
The utility model relates to a pressure pipe wound by polyethylene sandwich reinforcing rib plate belts in a reciprocated mode. The pressure pipe is characterized in that the pipe wall of the pressure pipe comprises a hot melting connecting layer of at least an upper layer of positive and negative spiral overlying wound sandwich reinforcing rib plate belt (2) and a lower layer of positive and negative spiral overlying wound sandwich reinforcing rib plate belt (2), reinforcing ribs (1) evenly paved along the axial direction are arranged between the upper layer of sandwich reinforcing rib plate belt (2) and the lower sandwich reinforcing rib plate belt (2), the length of the axial reinforcing ribs (1) is larger than or equal to that of the pressure pipe, at least one layer of parallelly arranged reinforcing ribs (1) is arranged in each sandwich reinforcing rib plate belt (2), and the reinforcing ribs (1) in the upper sandwich reinforcing rib plate belt (2) and the lower sandwich reinforcing rib plate belt (2) are overlaid spirally to form an interweaved and netted structure. The pressure pipe wound by polyethylene sandwich reinforcing rib plate belts in the reciprocated mode has the advantage that loading capacity of the pressure pipe is enhanced, and pressure pipes with large caliber can be manufactured.
Description
Technical field
The utility model relates to thermoplastic polyethylene, polypropylene pipe and tubing processing and the reciprocal pressure tube that twines of the sandwich stiffening rib strip of application, particularly a kind of polyethylene.
Background technique
At present, polyethylene pressure pipe road main technique takes extruding and moulding, external diameter typing to produce tubing, tubing maximum caliber 1600mm.Real wall PE pressure tubing takes extruding and moulding external diameter setting process to give birth to, and the maximum caliber of production is 1600mm.Woven polyethylene steel wire and polyethylene welded framework net compounding pressure tubing are taked to extrude, external diameter typing moulding process, adopt steel to mould complex form, and the tubing maximum caliber is less than 1600mm.And super large caliber is made greater than the PE pressure tube of DN1600, and the above-mentioned extruding and moulding production technology of finalizing the design outward can't be accomplished.
The model utility content
The purpose of this utility model provides a kind of heavy caliber, high-tensile, the pressure tube that back and forth twines of the sandwich stiffening rib strip of a kind of polyethylene of recycle and reuse again.
In order to finish above-mentioned purpose, the technical solution adopted in the utility model is:
The pressure tube that the sandwich stiffening rib strip of a kind of polyethylene is back and forth twined, the tube wall of described pressure tube comprises the sandwich stiffening rib strip hot melt tie layer that at least up and down two-layer forward-reverse spiral stack is twined, also be provided with up and down the stiffening rib of evenly laying vertically between the two-layer sandwich stiffening rib strip, the length of shaft orientation reinforcing rib is more than or equal to the length of pressure tube, the stiffening rib that is arranged in parallel that is at least one deck is set in every layer of sandwich stiffening rib strip, and the stack of the stiffening rib spiral in the two-layer sandwich stiffening rib strip forms the netted structure that interweaves up and down.
Described stiffening rib is glass fiber bundle, Steel Tendon or chemical fibre bundle.
Become 0 °-20 ° angle with the axial slices of pressure tube at the stiffening rib of laying between the two-layer sandwich stiffening rib strip up and down.
The tube wall of described pressure tube is that the sandwich stiffening rib strip hot melt connection that the stack of multilayer forward-reverse spiral is twined is made.
Leave spacing between the single arrangement of stiffening rib in the described sandwich stiffening rib strip.
The beneficial effects of the utility model are: adopt the stiffening rib of hot co-extrusion or two layers of polyethylene band double team word order to be prepared into sandwich stiffening rib strip, making sandwich stiffening rib strip forward-reverse spiral stack winding up and down, hot-melt polyethylene connects as one, it is the stiffening rib submission knitmesh shape structure of strip separately, the stiffening rib of arranging has vertically improved again longitudinally mechanical property of pipeline, the bearing capacity of pressure tube is strengthened, the Multi-layer reciprocating stack is twined, can produce bigbore pressure tube, satisfy the design pressure requirement.
