Embodiment 1

[0040] Embodiment 1: refer to figure 1 and figure 2

[0041]A plurality of slots 5 are arranged in the axial direction of the hole network pipe skeleton 1. The slots 5 are in the shape of a cuboid, and the bottom of the slots 5 is provided with a flange 6; There is a first groove 7 engaged with the flange 6; the production worker inserts the end of the connector 2 into the slot 5, and when the connector 2 touches the flange 6 at the bottom of the slot 5, an upward extrusion force is formed, and the The connecting piece 2 continues to be pushed into the slot 5 until the flange 6 of the slot 5 engages in the first groove 7 , thereby completing the fixing of the connecting piece 2 and the hole network pipe skeleton 1 . The slot 5 and the connecting piece 2 are simple in structure and easy to operate, and can significantly improve production efficiency.

[0042] The end of the connecting piece 2 and the flange 6 are provided with rounded corners. When the connecting piece 2 an...

Embodiment 2

[0044] Embodiment 2: refer to image 3 and Figure 4

[0045] The slot 5 is arranged as an annular groove, and at least four annularly distributed embedding grooves 8 are arranged on the annular groove (four are specifically shown in the accompanying drawings), and each embedding groove 8 is provided with a boss 9, and in the hole network pipe The frame 1 radially corresponds to the boss 9 and the first screw hole 10 is provided on the boss 9; The first screw hole 10 is passed through the first screw hole 10 by the bolt 11 to realize the fixing of the hole network pipe frame 1 and the connecting piece 2 .

[0046] During specific assembly, the production worker can put the end of the connector 2 into the slot 5 as a whole to fit, and then use the bolt 11 to penetrate the hole network pipe skeleton 1, the connector 2 and the first screw hole 10 on the boss 9 to screw together, In this way, the overall fixation of the hole network pipe skeleton 1 and the connecting piece 2 is...

Embodiment 3

[0048] Embodiment 3: refer to Figure 5 and Figure 6

[0049] The slot 5 is set as a cylindrical groove, the two ends of the connecting piece 2 are set as a cylindrical body, and the hole network pipe skeleton 1 is provided with a first semi-annular groove 12 at the cylindrical insertion part at both ends of the connecting piece 2; the specific first semi-annular groove The thickness of 12 is 0.5-1.0mm greater than the diameter of the through hole 101 of the hole network pipe skeleton 1, the height of the bottom of the first semi-annular groove 12 is 30-40% of the total thickness of the hole-net composite pipe, and the bottom of the first semi-annular groove 12 is provided with a trapezoidal groove 13. The lower part of the trapezoidal groove 13 has a taper of 20-30 degrees to the bottom of the hole-net composite pipe; the structure of the first semi-annular groove 12 is convenient for the connector 2 to be inserted into the slot 5 as a whole.

Abstract

The invention discloses a self-sealing type composite pipe seal and pipe fittings formed by the same. The self-sealing type composite pipe seal comprises at least two sections of hole net pipe frameworks, connecting pieces, an anti-corrosion outer layer and an anti-corrosion inner layer, wherein through holes are evenly and densely distributed in the surfaces of the hole net pipe frameworks, inserting grooves are formed in the hole net pipe frameworks in the axial direction, and the two ends of each connecting piece are fixed into the inserting grooves of the adjacent hole net pipe frameworks respectively; the connecting pieces are made of a non-metal composite material; and the outer surfaces of the hole net pipe frameworks and the outer surfaces of the connecting pieces are coated with the anti-corrosion outer layer, and the inner surfaces of the hole net pipe frameworks and the inner surfaces of the connecting pieces are coated with the anti-corrosion inner layer. According to the scheme, after a composite pipe is cut off at the positions of the connecting pieces, the connecting pieces seal the hole net frameworks, the sealing quality and strength and the pipeline use safety coefficient are improved, and compared with existing sealing operation after the composite pipe is cut off, secondary transferring operation of the pipe can be avoided, the production cost is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of composite pipes, and in particular relates to a self-sealing type composite pipe seal and the formed pipe fittings. Background technique [0002] The steel-plastic composite pipe is made of high-quality steel wire mesh or steel mesh skeleton as the reinforcement layer, and the high-quality steel mesh skeleton or steel mesh skeleton is wrapped in polyethylene plastic through extrusion molding, so as to produce high-strength, corrosion-resistant, etc. Composite pipe with excellent performance. [0003] Steel-plastic composite pipes mainly include steel skeleton polyethylene plastic composite pipes, steel wire wound polyethylene plastic composite pipes, and steel mesh skeleton polyethylene plastic composite pipes. Since this type of pipe uses steel skeleton as the reinforcement layer, and the inner and outer walls are covered with polyethylene plastic, etc., after production according to the fixed length, t...
