[0002] The intelligent plate heat exchanger unit is composed of plate heat exchangers, intelligent temperature control devices, intelligent electronic control devices and other circulating pump equipment. It adopts variable frequency pumps, electronically controlled valves, and automatically controllable electrical components. The operation process of the heat exchanger unit is realized through software programming, and the valve self-inspection and equipment automatic switching functions are realized. The original manual operation is transformed into automatic process control, and the operation process of the unit is visualized. It has the advantages of high efficiency, energy saving, intelligence, and automation.

[0003] The connecting water pipe is the most indispensable component in the plate heat exchanger unit. Since the pipe is made of metal and is large in size, it needs to be welded on the top of the base through a support rod during installation. The two adjacent pipes are connected by a flange to ensure airtightness. Due to the aging of parts over a long period of use, water leakage is most likely to occur at the connection position. However, since the pipe is usually welded on the top of the base, it is very inconvenient to disassemble and repair it. Utility Model Content

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-4 As shown, an intelligent plate heat exchanger unit includes a base 1, an electrical cabinet 2 for control is installed above the base 1, a plate heat exchanger 3 and a water pump 4 are installed above the base 1, and other equipment for heat exchange can also be installed above the base 1, and water pipes 5 are installed on the surfaces of the plate heat exchanger 3 and the water pump 4. The water pipes 5 are welded on the top of the base 1 and welded through support rods. A metal hose 6 is arranged between two of the water pipes 5, and the two water pipes 5 are connected with the inside of the metal hose 6. Flanges 7 are installed at both ends of the metal hose 6 and the port position of the water pipe 5, and bolts 8 are installed between adjacent flanges 7. Nuts 9 are sleeved on the surface of the bolts 8, and a support assembly is provided on the surface of the metal hose 6.

[0021] When inspecting the connection position of the flange 7, the bolts 8 and nuts 9 are removed from the surface of the flange 7, and then the metal hose 6 can be directly removed. The metal hose 6 can not only ensure the normal water flow function, but also because it can be bent, when the inspection is completed and the flange 7 is installed, its end can be stretched to ensure a tight connection between the flanges 7 and reduce the possibility of water leakage. However, due to the gravity of the metal hose 6 itself, the middle position will bend. As the use time increases, there is a greater risk of damage at this position. Therefore, a certain supporting force is provided by the support assembly to extend the service life of the metal hose 6.

[0022] The support assembly includes two support tubes 10, one end of each support tube 10 is installed on the surface of the flange 7, and each support tube 10 is sleeved on the surface of the metal hose 6. One of the support tubes 10 is sleeved on the surface of the other support tube 10. The metal hose 6 is located inside the support tubes 10, which can not only provide sufficient supporting force, but also protect the metal hose 6.

[0023] The flange 7 is fixedly welded to the support tube 10, and an annular groove 11 is opened at the port position of the flange 7. An annular plate 12 is fixedly welded to the surface of the metal hose 6. The annular plate 12 is fixed to the inside of the groove 11 through an installation component, and the side of the annular plate 12 is tightly attached to the inner wall of the groove 11. When the surface of the metal hose 6 needs to be inspected, it is only necessary to remove the annular plate 12 from the inside of the groove 11 and merge the two support tubes 10, so that the surface of the metal hose 6 can be clearly observed, which is convenient for inspection.

[0024] The installation assembly includes a plurality of studs 13, a plurality of circular holes 14 are provided on the surface of the annular plate 12, a plurality of thread grooves 15 are provided inside the groove 11, and the positions of the thread grooves 15 correspond one to one with the positions of the circular holes 14. The studs 13 movably pass through the circular holes 14 and are installed inside the thread grooves 15. When installing or disassembling, it is only necessary to unscrew or tighten the studs 13 from the inside of the thread grooves 15.

[0025] A rubber gasket 16 is installed inside the groove 11, and a through hole 17 is opened on the surface of the rubber gasket 16. The inner diameter of the through hole 17 is smaller than the diameter of the bolt 8 to ensure the seal between the rubber gasket 16 and the bolt 8. The main purpose of the rubber gasket 16 is to prevent water from flowing out of the inside of the support tube 10 and improve the sealing performance.

[0026] The support tube 10 and the flange 7 are formed integrally.

[0027] It should be noted that the utility model is an intelligent plate heat exchanger unit. When in use, when inspecting the connection position of the flange 7, the bolts 8 and nuts 9 are removed from the surface of the flange 7, and then the metal hose 6 can be directly removed. The metal hose 6 can not only ensure the normal water flow function, but also because it can be bent, when the inspection is completed and the flange 7 is installed, its end can be stretched to ensure a tight connection between the flanges 7 and reduce the possibility of water leakage. At the same time, the support pipe 10 provides a certain supporting force for the metal hose 6 to extend the service life of the metal hose 6. When the metal hose 6 needs to be inspected, the stud 13 is removed from the inside of the threaded groove 15, the annular plate 12 is taken out from the inside of the groove 11, and the two support pipes 10 are combined, so that the surface of the metal hose 6 can be clearly observed, which is convenient for inspection.
