Description

Technical Field

[0001] This utility model relates to the field of heat-insulated pipes, and in particular to a galvanized pipe with heat-insulating function. Background Technology

[0002] In industrial, construction, and municipal applications, the installation of insulated galvanized pipes must balance stability, ease of operation, and adaptability to thermal expansion and contraction. With the diversification of pipeline applications, the demand for installing pipes of different specifications is increasingly prominent. Furthermore, deformation of the pipe due to changes in medium temperature can easily damage the installation structure, placing higher demands on the design of mounting brackets.

[0003] Currently, the installation of insulated galvanized pipes mostly adopts a combination structure of traditional pipe clamps, L-shaped supports, and expansion bolts. The supports are fixed to the wall with expansion bolts, and the pipes are clamped with pipe clamps. Some installation racks add buffer pads inside the pipe clamps to reduce direct friction between the pipes and supports.

[0004] The existing mounting brackets have poor adaptability; one type of pipe clamp can only match a single pipe diameter. The installation process is cumbersome, requiring multiple adjustments to the position of the brackets and pipe clamps. When pipes are affected by thermal expansion and contraction, they are easily damaged by the rigid fasteners. Later disassembly and replacement of pipes requires the removal of the entire bracket, resulting in low maintenance efficiency. Utility Model Content

[0005] To address the aforementioned problems, this utility model proposes a galvanized pipe with heat insulation function, which more accurately solves the problems of poor adaptability, cumbersome installation process, and difficulty in meeting diverse needs.

[0006] This utility model is achieved through the following technical solution:

[0007] This utility model proposes a galvanized pipe with heat insulation function, including a heat-insulating galvanized pipe. The heat-insulating galvanized pipe includes a galvanized inner tube, a primer coating, a heat insulation layer, and a protective layer. The heat-insulating galvanized pipe is installed inside a mounting frame. The heat-insulating galvanized pipe and the mounting frame cooperate to realize the rapid installation and fixation of the galvanized pipe. The mounting frame includes fixing screws, nuts, connecting rings, load-bearing rings, and expansion joints.

[0008] Furthermore, the innermost layer of the heat-insulating galvanized pipe is a galvanized inner pipe, the outer side of the galvanized inner pipe is a primer coating, the primer coating is bonded with tubular heat-insulating material, and a protective layer is added to the outside of the heat-insulating layer.

[0009] Furthermore, the galvanized inner tube is made of low-carbon steel.

[0010] Furthermore, the fixing screw is installed on the wall surface, a connecting ring is fitted on the surface of the fixing screw, a nut is fitted on the surface of the fixing screw, the connecting ring is fixed by the nut, a load-bearing ring is fixedly connected to the bottom of the connecting ring, and an expansion joint is fixedly installed on the inner side of the load-bearing ring.

[0011] Furthermore, the top of the fixing screw is provided with a tapered protrusion and threads, and the length of the protruding end of the fixing screw is greater than the diameter of the load-bearing ring.

[0012] Furthermore, the connecting ring and the load-bearing ring are arranged in a cross shape.

[0013] Furthermore, the expansion and contraction sheet is circular, and a cross-shaped opening is provided in the middle of the expansion and contraction sheet.

[0014] The beneficial effects of this utility model are:

[0015] 1. The pipeline body adopts a multi-layer composite structure of "galvanized inner tube - primer coating - insulation layer - protective layer". The low carbon steel galvanized inner tube is hot-dip galvanized to form a 50-100μm zinc layer, which provides strong corrosion protection based on the sacrificial anode principle; the primer coating seals the pores and enhances the bonding force; the prefabricated tubular insulation layer effectively blocks heat exchange; and the outer protective layer improves the overall protection.

[0016] 2. The mounting bracket features an innovative design. Fixing screws and nuts allow for quick and easy attachment of the connecting ring and the cross-shaped load-bearing ring. The flexible rubber expansion joint inside the load-bearing ring adapts to different pipe sizes, enabling rapid installation. Simultaneously, the expansion joint provides a buffer for pipe expansion and contraction due to temperature differences, preventing pipe damage. Furthermore, the pipe can be directly removed from the expansion joint, significantly simplifying replacement and maintenance processes, balancing durability, convenience, and economy. It also reduces damage to the pipe under vibration, extending its service life. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more solutions or examples.

[0028] like Figures 1-4 As shown in the figure, an embodiment of this utility model proposes a galvanized pipe with heat insulation function, which includes a heat-insulating galvanized pipe and a mounting bracket. The heat-insulating galvanized pipe and the mounting bracket work together to achieve rapid installation and fixation of the galvanized pipe.

[0029] The insulated galvanized pipe consists of a galvanized inner tube 1, a primer coating 2, a heat insulation layer 3, and a protective layer. The innermost layer of the insulated galvanized pipe is the galvanized inner tube 1, which is made of low-carbon steel with good ductility and weldability. The low-carbon steel is processed into pipes of the required specifications and then galvanized using hot-dip galvanizing to form a zinc layer (typically 50-100μm thick) on the surface of the steel pipe. This process utilizes the "sacrificial anode" principle to protect the steel pipe body and prevent corrosion from water and air. After the galvanized inner tube 1 is prepared, rust removal is performed on the surface of the galvanized layer. This is done through sandblasting, pickling, and other methods to create a rough surface, increasing the contact area. Then, the primer coating 2 is applied. This special primer further seals the tiny pores in the galvanized layer and forms a chemical bond with the subsequent heat insulation layer 3, preventing the heat insulation layer 3 from peeling off. The insulation material is made into a tube shape, and an adhesive is applied to the surface of the primer coating 2. The insulation layer 3 is then placed over the steel pipe to block the transfer of heat and cold. Finally, a protective layer is added to the outside of the insulation layer 3 to protect the entire pipeline.

[0030] During the installation of the heat-insulated galvanized pipe, the mounting bracket is installed first. The mounting bracket includes fixing screws 7, nuts 8, connecting rings 6, load-bearing rings 4, and expansion joints 5. Fixing screws 7 are then installed on the wall surface. The top of the fixing screw 7 has a tapered protrusion and threads. When installing the fixing screw 7, the threads at the top are fully screwed into the wall. The protruding end of the fixing screw 7 is larger than the diameter of the load-bearing ring 4. After installing the fixing screw 7, the connecting ring 6 is fitted onto the surface of the fixing screw 7 and secured with the nuts 8. The bottom of the connecting ring 6 is fixedly connected to... The load-bearing ring 4 and the connecting ring 6 are arranged in a cross shape. An expansion joint 5 is fixedly installed inside the load-bearing ring 4. The expansion joint 5 is a circular piece with a cross-shaped opening in the middle. The expansion joint 5 is made of a flexible rubber material. Different specifications of heat-insulated galvanized pipes can be installed on the expansion joint 5. The tightened nut 8 presses the load-bearing ring 4 against the wall, and the position of the load-bearing ring 4 is fixed. The mounting bracket is then fixed. The heat-insulated galvanized pipe is passed through the opening of the expansion joint 5 inside the load-bearing ring 4. The heat-insulated galvanized pipe is installed as a whole inside the load-bearing ring 4, realizing the simple installation of the heat-insulated galvanized pipe.

[0031] The heat-insulated galvanized pipe is installed inside the expansion joint 5, which not only enables simple installation and fixation of the heat-insulated galvanized pipe, but also allows for easy removal of the heat-insulated galvanized pipe from the mounting bracket when it needs to be replaced, saving disassembly and installation time.

[0032] The external environment and the temperature changes of the internal materials of the heat-insulated galvanized pipe can cause the overall expansion and contraction of the heat-insulated galvanized pipe. The setting of the expansion and contraction plate 5 provides the heat-insulated galvanized pipe with a certain expansion and contraction space, avoiding the pipe body damage caused by the expansion and contraction of the heat-insulated galvanized pipe itself during fixed installation, and increasing the service life of the heat-insulated galvanized pipe.

[0033] The pipeline body employs a multi-layer composite structure consisting of a galvanized inner tube 1, a primer coating 2, a heat insulation layer 3, and a protective layer. The low-carbon steel galvanized inner tube 1 undergoes hot-dip galvanizing to form a 50-100μm zinc layer, providing strong corrosion protection based on the sacrificial anode principle. The primer coating 2 seals pores and enhances adhesion, while the prefabricated tubular heat insulation layer 3 efficiently blocks heat exchange, and the outer protective layer improves overall protection. The mounting bracket design is highly innovative, with fixing screws 7 and nuts 8 quickly securing the connecting ring 6 and the cross-shaped load-bearing ring 4. The flexible rubber expansion joint 5 inside the load-bearing ring 4 can adapt to different pipe specifications, enabling rapid installation. Simultaneously, the expansion joint 5 provides buffer space for the expansion and contraction of the pipeline due to temperature differences, preventing pipe damage. Furthermore, the pipeline can be directly removed from within the expansion joint 5, significantly simplifying replacement and maintenance processes, balancing durability, convenience, and economy. It also reduces damage to the pipeline under vibration, extending its service life.
