Embodiment 1

[0077] Such as figure 1 Shown: a hot water circulation system, including a water heater 6, a circulating pump 2, a non-return type starting valve 4, a hot water pipe composed of a hot water pipe and a pipe joint 7, and a connection to an external device 3 Tail valve 5. The external device 3 may be a faucet, a shower, a radiator and so on.

[0078] The liquid inlet end of the circulating pump 2 is connected to the output end of the water heater, and the output end is connected to the non-return type starting valve 4;

[0079] The non-return type starting valve 4 includes a starting valve body 401. The starting valve body 401 is provided with a starting valve inlet A402 connected to the output of the water heater 6 and a starting valve inlet connected to the output of the circulating pump. Liquid end B403, initial valve outlet 404 connected to the input end of the water heater, and initial valve connection end 405 connected to the hot water pipe; the water heater input is also conne...

Embodiment 2

[0135] 【Tail Valve A】

[0136] Such as Figure 35 , 14 -16: This embodiment is basically the same as the first embodiment. The difference lies in the structure of the tail valve 5. The tail valve A includes a hollow tail valve body A201, and the tail valve body A201 is provided with a connecting pipe The tail valve inlet end A202 of the middle pipe 1 and the tail valve outlet end A204 used to connect to external equipment 3 such as faucets. The tail valve body A201 is coaxially provided with a corresponding tail valve inner pipe A210. The coaxial arrangement of the pipe A210 and the tail valve body A201 is convenient for installation. In addition, the inner wall of the tail valve body A201 and the outer wall of the tail valve inner tube A210 are connected to each other through at least one tail valve connecting rib A205. The number of the connecting ribs 105 can be 2, 3, 4... and they are evenly distributed in the circumferential direction to facilitate the tail Fixing of A210 i...

Embodiment 3

[0155] Such as Figure 36 As shown: this embodiment is basically the same as the first embodiment, and the difference is that this embodiment is mainly applied in the sanitary room.

[0156] The output end of the hot water pipeline is provided with a floor heating system for toilet heating or / and a radiator system for drying towels and clothes;

[0157] The geothermal system includes a geothermal pipe 30 and a controller A34. The geothermal pipe 30 includes a geothermal outer pipe 31 with a heat conduction function and a geothermal inner pipe 32 with a thermal insulation function. The geothermal inner pipe 32 passes at least A reinforcing rib C33 is coaxially arranged in the geothermal outer pipe 31, the geothermal inner pipe 32 is provided with a hot water channel, and the geothermal outer pipe 31 is provided with a return water channel, and the cross-sectional area of ​​the hot water channel is equal to The cross-sectional area of ​​the return water flow channel, and through the ...

Abstract

The invention belongs to the technical field of domestic water and particularly relates to a hot water circulation system. The hot water circulation system comprises a water heater, a circulation pump, a non-return start valve, a hot water pipeline, and tail valves connected with external equipment, wherein the hot water pipeline is composed of hot water pipes and a pipe joint. The liquid inlet end of the circulation pump is connected with the output end of the water heater, and the output tend of the circulation pump is connected with the non-return start valve. A hot water runner communicating with a liquid inlet cavity of the start valve and a water return runner communicating with a backflow cavity of the start valve are arranged in each hot water pipe. The liquid outlet end of each hot water pipe is provided with one tail valve. Each tail valve comprises a tail valve. A tail valve liquid inlet cavity communicating with the corresponding hot water runner and a tail valve backflow cavity communicating with the corresponding backflow runner are arranged in each tail valve body. The tail valve liquid inlet cavities and the tail valve backflow cavities can communicate with the external equipment. The hot water circulation system has the characteristics of energy saving, environmental friendliness, convenient pipeline layout, low cost, quick water producing and the like.

Description

Technical field [0001] The invention belongs to the technical field of domestic water, and specifically refers to a hot water circulation system. Background technique [0002] At present, in the field of hot water supply, the old-fashioned single pipe is generally used to supply hot water, which is popular with consumers because of its convenient installation and low cost, and has gradually become the industry installation specification and industry installation standard. However, when the single pipe pipeline is relatively long, a large amount of cold water in the pipeline needs to be vented before using hot water, which leads to a long waiting time for hot water and also causes a lot of waste of water resources. [0003] With the continuous advancement of science and technology, the concept of hot water circulation pipelines has been introduced in the field of hot water supply. The hot water inlet pipe, hot water return pipe and cold water pipe are required in the hot water circu...
