The hot water or steam produced in the boiler can directly provide the required thermal energy for industrial production and people's lives, or can be converted into mechanical energy through a steam power device, or mechanical energy can be converted into electrical energy through a generator. A boiler that provides hot water is called a hot water boiler, which is mainly used for life and also has a small number of applications in industrial production.

[0003] The existing boiler hot water recirculation pipeline can refer to the utility model patent with Chinese patent announcement number CN209743885U, which discloses a boiler pipeline insulation device and a boiler having the same, wherein the boiler pipeline insulation device includes: an outer jacket made of a flexible material, the outer jacket is arranged around the outer side of the boiler pipeline; and an inner core is filled into the outer jacket. The technical solution of the utility model can effectively solve the problem that the insulation device of the boiler pipeline in the prior art is easily damaged when disassembled.

[0004] Although the above technical solution solves the problem that the insulation device is easily damaged during disassembly, the above technical solution fixes the insulation device by setting interval fixed connecting parts when installing the insulation device. When the insulation device hits the bent part of the pipeline during installation and is located at the interval between two connecting parts, the protective device cannot be fixed by the connecting parts, affecting the protective effect of the protective device. Therefore, the present application provides a boiler hot water recirculation pipeline to meet the needs. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a boiler hot water recirculation pipeline to solve the problem that when the existing insulation device is installed, it is fixed by setting interval fixed connecting parts. When the insulation device is installed, it hits the pipeline bending part and is located at the interval position between two connecting parts, resulting in the protection device cannot be fixed by the connecting parts, affecting the protection effect of the protection device.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0007] A boiler hot water recirculation pipeline comprises: a pipeline body, an outer wall of the pipeline body is sheathed with a protective sleeve, a fixing belt is fixedly installed on one end of the outer wall of the protective sleeve, a Velcro mother patch is fixedly installed on the other end of the outer wall of the protective sleeve, a buckle body is clamped on the outer wall of the fixing belt, a Velcro sub-patch is fixedly connected to the top of the buckle body, an ear plate with a transverse through hole is fixedly connected to the side wall of the buckle body, a clamping plate is rotatably connected to the inner cavity of the clamping body, and a number of tiger teeth are fixedly installed on the bottom of the clamping plate.

[0008] Preferably, a fixing block is fixedly installed on the top of the fang, a latch is slidably connected to the inner cavity of the fixing block, a handle is fixedly installed on one end of the latch, a blocking piece is fixedly installed on the outer wall of the other end of the latch, and a spring is sleeved on the outer wall of the latch.

[0009] Preferably, one end of the spring is fixedly connected to the outer wall of the fixing block, and the other end of the spring is fixedly connected to the outer wall of the blocking piece.

[0010] Preferably, the protective cover is provided with an inner core, and the inner core of the protective cover is made of glass fiber woven felt.

[0011] Preferably, the latch is matched with the through hole on the ear plate.

[0012] Preferably, the position of the buckle body on the fixing belt is adjustable.

[0013] Compared with the prior art, the utility model has at least the following beneficial effects:

[0014] 1. In the above scheme, the position of the buckle body can be adjusted by rotating the clamping plate to open it, and the clamping plate is closed after the buckle body is adjusted to a suitable position, so that the clamping plate clamps the fixing belt through the tiger teeth, so that the buckle body is fixed on the fixing belt, thereby solving the problem that when the existing thermal insulation device is installed, it is fixed by setting interval fixed connecting pieces. When the thermal insulation device is installed, it encounters the bending part of the pipeline and is located at the interval position of the two connecting pieces, resulting in the protection device being unable to be fixed by the connecting piece, affecting the protection effect of the protection device.

[0015] 2. In the above scheme, the latch is driven to move backward by pulling the handle. When the latch is pulled, the spring is squeezed by the fixed block and the baffle. When the spring is no longer squeezed, the latch is reset under the action of its own elastic force. When the card plate is buckled, the latch is inserted into the ear plate, thereby limiting the card plate so that the card plate cannot be opened without external force.

[0030] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a boiler hot water recirculation pipeline, comprising: a pipeline body 1, the outer wall of the pipeline body 1 is provided with a protective sleeve 2, one end of the outer wall of the protective sleeve 2 is fixedly installed with a fixing belt 3, the other end of the outer wall of the protective sleeve 2 is fixedly installed with a Velcro mother patch 4, the outer wall of the fixing belt 3 is clamped with a buckle body 5, the top of the buckle body 5 is fixedly connected with a Velcro sub-patch 6, the side wall of the buckle body 5 is fixedly connected with an ear plate 7 with a transverse through hole, the inner cavity of the buckle body 5 is rotatably connected with a clamping plate 8, and a number of tiger teeth 9 are fixedly installed on the bottom of the clamping plate 8.

[0031] like Figure 1 and Figure 2 As shown, a fixing block 10 is fixedly installed on the top of the fang 9, and a latch 11 is slidably connected to the inner cavity of the fixing block 10, a handle 12 is fixedly installed on one end of the latch 11, and a baffle 13 is fixedly installed on the outer wall of the other end of the latch 11, and a spring 14 is sleeved on the outer wall of the latch 11. The handle 12 is pulled to drive the latch 11 to move backward. When the card plate 8 is buckled, the latch 11 will be inserted into the ear plate 7, thereby limiting the card plate 8 so that the card plate 8 cannot be opened without external force.

[0032] like Figure 2 and Figure 4 As shown, one end of the spring 14 is fixedly connected to the outer wall of the fixed block 10, and the other end is fixedly connected to the outer wall of the baffle 13. When the latch 11 is pulled, the spring 14 is squeezed by the fixed block 10 and the baffle 13. When the spring 14 is no longer squeezed, the latch 11 is reset under the action of its own elastic force.

[0033] like Figure 1 and Figure 3 As shown, the protective cover 2 is provided with an inner core, and the inner core of the protective cover 2 is made of a glass fiber woven felt blanket. The glass fiber woven felt blanket has good thermal insulation performance and can better retain the temperature of the pipeline body 1.

[0034] like Figure 2 and Figure 4 As shown, the latch 11 is matched with the through hole on the ear plate 7, and the latch 11 is inserted into the ear plate 7, thereby limiting the clamping plate 8, so that the clamping plate 8 will not open after closing, ensuring the stability of the clamping.

[0035] like Figure 1 and Figure 4 As shown, the position of the buckle body 5 on the fixing belt 3 can be adjusted. By adjusting the position of the buckle body 5, the buckle body 5 can better fix the protective cover 2, so that the protective cover 2 can also be better fixed when it is bent, making the device more flexible.

[0036] The technical solution provided by the utility model is to open the card plate 8 by rotating it, so that the position of the buckle body 5 can be adjusted. After the buckle body 5 is adjusted to a suitable position, the card plate 8 is closed, so that the card plate 8 clamps the fixing belt 3 through the tiger teeth 9, so that the buckle body 5 is fixed on the fixing belt 3, and the latch 11 is driven to move backward by pulling the handle 12. When the latch 11 is pulled, the spring 14 is squeezed by the fixing block 10 and the blocking sheet 13. When the spring 14 is no longer squeezed, the latch 11 is reset under the action of its own elastic force. When the card plate 8 is buckled, the latch 11 is inserted into the ear plate 7, thereby limiting the card plate 8, so that the card plate 8 cannot be opened without external force.

[0037] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention.
