Description

Technical Field

[0001] This utility model relates to the field of water pipe technology, specifically a pressure-resistant water supply pipe. Background Technology

[0002] In the existing technology, traditional water supply pipes have the following defects: insufficient pressure resistance: single-layer structure pipes are prone to rupture due to external loads or water hammer impact, resulting in leakage; high water flow resistance: straight-through pipes are prone to turbulence, increasing pumping energy consumption; poor durability: after long-term use, the inner wall is prone to corrosion or scaling, reducing throughput and water quality safety; therefore, we propose a pressure-resistant water supply pipe.

[0004] This utility model provides the following technical solution: a pressure-resistant water supply pipe, comprising: an outer pipe, a pressure-resistant layer, and an inner pipe. The pressure-resistant layer is disposed between the outer pipe and the inner pipe, and can be integrally formed with the outer pipe and the inner pipe. The inner wall of the inner pipe is coated with an antibacterial layer, and the inner wall of the inner pipe is also provided with a flow guide groove, which is a spiral design. The outer surface of the outer pipe is coated with an anti-corrosion layer. The pressure-resistant layer includes a pre-embedded rod and a node ring. A reinforcing mesh is fixedly installed on the side of the node ring. A node seat is fixedly installed on the body of the pre-embedded rod. An insertion rod is fixedly installed on the side of the node ring adjacent to the node seat. A protruding ridge is fixedly installed on the outer surface of the insertion rod. An insertion hole for insertion with the insertion rod is opened on the node seat. A screw is fixedly installed at the end of the pre-embedded rod that passes through the outer pipe.

[0005] Preferably, the outer and inner pipes are made of thermoplastic polyurethane to form the water pipe matrix.

[0006] Preferably, the node ring, reinforcing mesh, and pre-embedded rod are all embedded inside the water pipe body.

[0007] Preferably, the socket has a slot inside, and the slot has a ring structure design.

[0008] Preferably, the shape of the protruding ridge is consistent with the shape of the slot, both being annular structures, and the protruding ridge can cooperate with the slot.

[0009] Preferably, the boundary between the slot and the protrusion is designed with rounded corners for a smooth transition.

[0010] Preferably, the length of the insertion rod is the same as the length of the insertion hole.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This pressure-resistant water supply pipe is composed of a multi-layered composite structure consisting of an outer pipe, a pressure-resistant layer, and an inner pipe. A reinforcing mesh made of steel wire enhances the overall pressure resistance, and a flow guide channel is installed inside the inner pipe. The spiral flow guide channel reduces water flow resistance and energy consumption. Simultaneously, the inner surface of the inner pipe can be coated with antibacterial and anti-corrosion layers, which work synergistically to extend the overall lifespan of the pipe. The screw can be fixed to a pre-embedded rod inside the pipe, facilitating quick connection and improving installation efficiency and convenience. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5 A pressure-resistant water supply pipe includes: an outer pipe 1, a pressure-resistant layer 2, and an inner pipe 3. The pressure-resistant layer 2 is disposed between the outer pipe 1 and the inner pipe 3, and the pressure-resistant layer 2 can be integrally formed with the outer pipe 1 and the inner pipe 3. The inner wall of the inner pipe 3 is coated with an antibacterial layer, and the inner wall of the inner pipe 3 is also provided with a flow guide groove 5, which is a spiral design. The outer surface of the outer pipe 1 is coated with an anti-corrosion layer. The outer pipe 1 and the inner pipe 3 are made of thermoplastic polyurethane to form the water pipe matrix. The antibacterial layer of the inner pipe 3 is a high-density polyethylene (HDPE) layer containing nano-silver ions to inhibit the growth of microorganisms. The anti-corrosion layer of the outer pipe 1 is a polyamide epoxy resin coating, which is resistant to ultraviolet rays and chemical corrosion.

[0021] The pressure-resistant layer 2 includes a pre-embedded rod 23 and a node ring 21. A reinforcing mesh 22 is fixedly installed on the side of the node ring 21. A node seat 24 is fixedly installed on the body of the pre-embedded rod 23. An insert rod 25 is fixedly installed on the side of the node ring 21 adjacent to the node seat 24. A protruding ridge 26 is fixedly installed on the outer surface of the insert rod 25. An insertion hole 28 for inserting the insert rod 25 is opened on the node seat 24. A screw 4 is fixedly installed at the end of the pre-embedded rod 23 that passes through the outer pipe 1. The node ring 21, the reinforcing mesh 22, and the pre-embedded rod 23 are all embedded inside the water pipe body. The insertion hole 28 is opened inside... There is a slot 27, which is a ring structure design. The shape of the protrusion 26 is the same as that of the slot 27, both being ring structures. The protrusion 26 can cooperate with the slot 27. The boundary between the slot 27 and the protrusion 26 is a rounded corner design for smooth transition. The length of the insertion rod 25 is the same as the length of the insertion hole 28, so that the node ring 21 and the node seat 24 can be quickly spliced ​​together, thereby allowing multiple reinforcing meshes 22 to be quickly combined to form a pressure-resistant layer 2.
