Description

Technical Field

[0001] The utility model relates to the technical field of water heating pipe fittings, in particular to a connecting pipe used for water heating pipe fittings. Background Art

[0002] Water heating is one type of floor radiation heating and is also the most popular heating method. It has considerable advantages over electric heating. Water heating uses floor coils with hot water circulating in the pipes. The heat medium in the floor radiation layer evenly heats the entire floor. The heat storage of the floor itself and the law of upward radiation of heat are used to conduct heat from bottom to top to achieve the purpose of heating. Because a gradually decreasing temperature gradient from the soles to the head is formed indoors, people can feel the comfort of warm feet and cool head.

[0003] Most of the common plumbing pipe connecting pipes on the market cannot be bent, which brings a lot of trouble in practical applications. For example, the utility model with patent number CN219082521U, when encountering an installation environment that requires turning or detouring, this rigidly designed connecting pipe is extremely inconvenient. Due to the complexity of the plumbing system, various angles and directions of adjustment are often encountered during the installation process. Traditional straight connecting pipes are often unable to adapt effectively to these requirements, resulting in obstructions to installation work and even affecting the progress and quality of the entire project. In addition, forcibly bending these inflexible connecting pipes may cause damage to the pipes, causing safety hazards such as leakage, and bring additional burdens to later maintenance.

[0024] See also Figure 1-7The utility model provides a technical solution: a connecting pipe for water heating pipes, including a water pipe 1, the water pipe 1 is surrounded by a layer of flexible corrugated pipe 12 on the outside, the flexible corrugated pipe 12 is surrounded by a cushion layer 13 on the outside, the cushion layer 13 is surrounded by a sealing layer 17 on the outside, the sealing layer 17 is surrounded by a heat preservation layer 16 on the outside, the heat preservation layer 16 is surrounded by an outer shell 11 on the outside, the outer shell 11, the heat preservation layer 16, the sealing layer 17 and the cushion layer 13 are provided with telescopic pipes 8 at both ends, and the first connecting flange 2 and the second connecting flange 3 are fixed to the two ends of the water pipe 1 respectively. The connecting flange 9, the first connecting flange 2 and the second connecting flange 9 are each provided with a plurality of fixing seats 3 arranged in a ring shape on their sides, wherein a pull strap 4 is provided on each of the fixing seats 3 provided on the side of the first connecting flange 2, and a clamping block 6 is provided at the end of each pull strap 4 away from the fixing seat 3, and an adjusting bolt 18 is provided in each clamping block 6, and an adjusting belt 7 is sleeved on the side of each adjusting bolt 18 in the clamping block 6, and the adjusting belt 7 is pushed to move by the rotation of the adjusting bolt 18 to adjust the exposed length of the adjusting belt 7, and then cooperates with the pull strap 4 and the fixing seat 3 to finally pull the connecting pipe to bend.

[0025] Furthermore, the flexible bellows 12 and the water pipe 1 are fixed together by bonding, and the flexible bellows 12 provides support for the water pipe 1 to prevent the water pipe 1 from folding when bending, thereby preventing the internal water flow from being blocked.

[0026] Furthermore, talcum powder is coated between the cushion layer 13 and the flexible bellows 12 , and the cushion layer 13 is used to protect the sealing layer 17 to prevent the flexible bellows 12 and the sealing layer 17 from excessive friction and damage to the sealing layer 17 when bending.

[0027] Furthermore, a layer of talcum powder is coated between the sealing layer 17 and the heat-insulating layer, and between the heat-insulating layer 16 and the outer shell 11, to provide a sliding friction environment and prevent damage to components due to excessive friction resistance.

[0028] Furthermore, the side thread of the adjusting bolt 18 is deeper and a cross opening 15 is provided at one end of the adjusting bolt 18 . A plurality of bayonet openings 14 are provided on the adjusting belt 7 . The bayonet openings 14 cooperate with the rotation of the adjusting bolt 18 to push the adjusting belt 7 to move.

[0029] Furthermore, a fixing block 5 is provided on the side of the first connecting flange 2, and a nut 10 is provided on the side of the second connecting flange 9. The fixing block 5 and the nut 10 are used together to connect the pipeline.

[0030] Working principle: Before use, first determine the angle at which the connecting pipe needs to be bent. After determining the bending angle, insert the end of a cross screwdriver into the cross opening 15 and rotate it, thereby driving the adjusting bolt 18 to rotate. The adjusting bolt 18 rotates and pushes the adjusting belt 7 to move through the bayonet 14, and then cooperates with the drawstring 4 to make it retractable. The connecting pipe is driven to bend toward one side of the adjustment through the fixing seat 3 set at the end of the drawstring 4 and the adjusting belt 7, and the opposite side only needs to rotate the adjusting bolt 18 in the opposite direction to extend the adjusting belt 7.

[0031] When the connecting pipe is bent, due to the inextensibility of the outer shell 11, the insulation layer 16, the sealing layer 17 and the cushion layer 13, the telescopic tubes 8 at both ends thereof make stretching compensation to prevent the first connecting flange 2 and the second connecting flange 9 from detaching from the outer shell 11, the insulation layer 16, the sealing layer 17 and the cushion layer 13, causing the water pipe 1 to be exposed.

[0032] When the connecting pipe is bent, the flexible corrugated pipe 12 inside is also bent, and provides support for the water pipe 1 inside, thereby preventing the water pipe 1 from folding when it is bent, resulting in poor water flow.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
