Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-5, the present invention provides the following technical solutions: the utility model provides a rapid Assembly's water heater, includes the water tank, and the water tank is equipped with shell 1, inner bag 2 and heat preservation, is equipped with heat transfer coil pipe 3 in inner bag of water tank 2, and water tank one end is equipped with heat transfer inlet tube 4 and the heat transfer outlet pipe 5 that are linked together with inner bag 2, and heat transfer inlet tube 4 and heat transfer outlet pipe 5 are stainless steel pipe fitting. Heat transfer inlet tube 4 and heat transfer outlet pipe 5 dress are on the same side end lid of water tank, all are equipped with external screw thread 6 on the heat transfer inlet tube 4 that stretches out water tank shell 1 and the 5 outer walls of heat transfer outlet pipe, and external screw thread 6 is used for the connecting pipeline. The heat exchange coil 3 is provided with a water inlet connecting part 7 and a water outlet connecting part, the water inlet connecting part 7 and the water outlet connecting part are thin-wall stainless steel pipes, and the water inlet connecting part 7 and the water outlet connecting part are respectively inserted into the heat exchange water inlet pipe 4 and the heat exchange water outlet pipe 5 and are in expanded connection and sealing connection.
During assembly, the water inlet connecting part 7 and the water outlet connecting part are respectively inserted into the heat exchange water inlet pipe 4 and the heat exchange water outlet pipe 5 from one end without the external thread 6, the expanded connection part of the pipe expander is inserted into the expanded connection section of the water inlet connecting part 7 and the water outlet connecting part, and the expanded connection part needs to be cooled by cooling liquid during expansion connection. In order to protect the tube expander, lubricating liquid is added on the tube expander in the implementation process. After expansion connection, the two ends of the heat exchange coil 3 are hermetically connected with the heat exchange water inlet pipe 4 and the heat exchange water outlet pipe 5, so that the thin-walled pipe is converted into a threaded pipe. Therefore, the assembling mode is simple to operate and high in speed, the pipe expander can be used for assembling, meanwhile, the pipe expander can be operated at a user side according to needs, and the pipe expander is not limited to application places and is wide in application range.
In order to further improve the sealing effect, the method is implemented by another embodiment, which is as follows:
