DETAILED DESCRIPTION

[0015] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0016] A water supply device for a plate heat exchanger unit, such as Figure 1 、 2 As shown in Figure 3, it includes a tank body 1, the top of the tank body 1 is open and a coaxial sealing cover 2 is hingedly installed, the bottom of the sealing cover 2 is in contact with the top of the tank body 1, and a coaxial partition 3 is fixedly installed in the tank body 1. The partition 3 divides the interior of the tank body 1 into two parts, an upper chamber 4 and a lower chamber 5. Several gas filling pipes 6 are installed on the sealing cover 2, and the left and right sides of the side wall of the lower chamber 5 are connected and installed in sequence. A plurality of through grooves 10 are provided on the partition 3, and elastic membranes 11 are respectively connected on the through grooves 10. Several first vertical pipes 9 are fixedly installed on the sealing cover 2 corresponding to the gas filling pipe 6, and the bottoms of the first vertical pipes 9 are in contact with the top of the partition 3 respectively. The first vertical pipe 9 connects the corresponding gas filling pipe 6 and the elastic membrane 11, and the gas filling pipe 6 is coaxially arranged with the corresponding first vertical pipe 9 and the through groove 10. The utility model has a simple structure and an ingenious design. When one of the elastic membranes 11 is damaged, the other elastic membranes 11 can still perform pressure regulation work without affecting the use. Moreover, only the damaged small elastic membrane 11 needs to be replaced, thus avoiding the waste of the elastic membrane 11, meeting market demand, and being suitable for promotion. When using the utility model, the tank body 1 is placed in a suitable position, and air is added to the space surrounded by the first vertical pipe 9, the partition 3, and the elastic membrane 11 through the air filling pipe 6. The elastic membrane 11 expands and bulges into the lower chamber 5. Water is injected into the lower chamber 5 through the water inlet pipe 8. During the water injection process, the pressure in the lower chamber 5 increases, and the elastic membrane 11 bulges toward the upper chamber 4 under the action of the water pressure until the gas pressure in the upper chamber 4 and the water pressure in the lower chamber 5 reach a pressure balance, and the water supply is stopped; when a certain elastic membrane 11 When damaged, the remaining elastic membrane 11 can still continue to adjust the pressure in the upper chamber 4 and the lower chamber 5, so that the upper chamber 4 and the lower chamber 5 reach a pressure balance and do not affect use. When the water supply is completed, the sealing cover 2 is rotated along the hinge axis of the sealing cover 2 and the tank body 1 to open the sealing cover 2. The first vertical pipe 9 rotates with the sealing cover 2, and the damaged elastic membrane 11 is removed from the through groove 10. Then, a new elastic membrane 11 is replaced. After the replacement is completed, the sealing cover 2 is rotated to close, and the first vertical pipe 9 is rotated to abut and contact with the partition 3.

[0017] Specifically, as shown in the figure, one side of the sealing cover 2 and the corresponding side of the tank body 1 are respectively fixedly mounted with a first transverse plate 20, and the two first transverse plates 20 are in contact with each other. The first transverse plates 20 are respectively provided with through holes 21, and bolts 22 are respectively provided in the through holes 21 for sliding engagement. One end of the bolt 22 is threadedly engaged with a nut 23, and the through holes 21, the bolt 22 and the nut 23 are coaxially arranged. The nut 23 is in contact with the side of the adjacent first transverse plate 20. When the sealing cover 2 is to be rotated to open, the nut 23 is screwed to move the nut 23 in a direction away from the first transverse plate 20 until the nut 23 is no longer threadedly engaged with the bolt 22, and the bolt 22 is removed from the through hole 21. At this time, the sealing cover 2 can be rotated along the hinge axis between the sealing cover 2 and the tank body 1 to open; similarly, the sealing cover 2 is rotated to close, the bolt 22 is slidably mounted in the two through holes 21, and the nut 23 is then threadedly engaged with the bolt 22, thereby limiting the position of the sealing cover 2 and preventing it from being rotated open.

[0018] Specifically, as shown in the figure, the air filling pipe 6, the drain pipe 7 and the water inlet pipe 8 of this embodiment are connected and installed with valves 30. The valves 30 are used to facilitate the control of the air intake, water intake and drainage.

[0019] Furthermore, as shown in the figure, the elastic membrane 11 of this embodiment is respectively connected to and installed with a second vertical tube 40, and the second vertical tube 40 passes through the corresponding through groove 10 and is slidably installed in the corresponding through groove 10. The second vertical tube 40 is coaxially arranged with the corresponding through groove 10, and the outer periphery of the upper end of the second vertical tube 40 is respectively fixedly installed with a coaxial ring 41, and the upper end of the ring 41 is flush with the upper end of the second vertical tube 40. The ring 41 is located above the partition 3 and is in contact with the partition 3. The second vertical tube 40 and the corresponding ring 41 and the elastic membrane 11 are an integrated structure, and the first vertical tube 9 is in contact with the partition 3 through the ring 41. The second vertical tube 40 is slidably installed in the corresponding through groove 10, and the ring 41 rests on the partition 3, so that the elastic membrane 11 can be detachably installed on the partition 3. When the elastic membrane 11 is damaged and needs to be replaced, the ring 41, the second vertical tube 40 and the elastic membrane 11 can be directly removed from the partition 3, and can be quickly replaced. The first vertical tube 9 rests on the partition 3 through the ring 41, so that the ring 41, the second vertical tube 40 and the elastic membrane 11 are more stably installed on the partition 3.

[0020] Furthermore, as shown in the figure, a pressure detector 50 is installed on the side wall of the lower chamber 5 in this embodiment. The pressure detector 50 is used to observe the pressure in the lower chamber 5.

[0021] Furthermore, as shown in the figure, in this embodiment, the second vertical tube 40, the circular ring 41, and the elastic membrane 11 are all made of rubber. The circular ring 41 is pressed against the partition 3 via the first vertical tube 9. Since the circular ring 41 is made of rubber, it fits tightly against the partition 3, improving the sealing between the bottom of the circular ring 41 and the top of the partition 3, preventing the upper chamber 4 and the lower chamber 5 from communicating.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
