Description

Technical Field

[0001] The utility model relates to the technical field of boiler equipment, in particular to a vacuum phase-change hot water boiler. Background Art

[0002] Vacuum phase change hot water boiler, also known as vacuum boiler, is a special type of hot water boiler. Its core working principle is to form a negative pressure vacuum environment inside the closed furnace body. In this environment, heat medium water is filled and heated, and then the heat energy is transferred to the water that needs to be heated through the evaporation and condensation process of the heat medium water.

[0003] In the prior art, a vacuum phase change hot water boiler includes a furnace body, a combustion device, a smoke exhaust device, a negative pressure steam chamber, etc. Water usually enters the pipe from the water inlet. In order to increase the contact time, the pipe in the cavity is set in an S shape. After heating, it flows out from the water outlet pipe and is then sent to the area to be used.

[0004] However, if only one S-shaped pipe is set up, the heat exchange area is fixed and small, so that the water in some areas cannot be fully heated, resulting in low heating efficiency. In addition, the flow rate of a single pipe is fixed, which makes it inconvenient to flexibly adjust the flow and temperature. In addition, the water inlet and the pipe are connected by a flange. After long-term use, the bolts fixing the flange are prone to loosening, resulting in gaps between the flanges, reducing the sealing of the connection, and easily causing water leakage and seepage.

[0025] See also Figure 3 to Figure 4On the basis of the first embodiment, in order to achieve a stable connection between the water inlet main pipe 4 and the water inlet branch pipe 7, the connecting sleeve 8 is an annular plate structure with an I-shaped cross section, and rubber grooves 15 are provided on both sides of the connecting sleeve 8.

[0027] Embodiment 3

[0028] See also Figures 5 and 6 On the basis of the second embodiment, in order to clamp and tighten the bolt 12, the two side surfaces of the circular hole 14 are overlapped with ring plates 18, the ring plates 18 are annular plates, and the surface of the ring plates 18 is provided with a limiting groove 19, the limiting groove 19 is an annular groove, and the surface of the rubber groove 15 is provided with slots 11 on both sides, the slots 11 are square slots, the slots 11 are connected with the limiting grooves 19, and the slots 11 are penetrated with a limiting block 20 slidably installed in the limiting groove 19, the limiting block 20 is a square block structure, and one end of the limiting block 20 is fixedly connected to the surface of the circular hole 14.

[0029] The slot 11 on the surface of the ring plate 18 is just enough for the limit block 20 to pass through. When the limit block 20 passes through the slot 11 and reaches the limit groove 19, the ring plate 18 is rotated at a certain angle so that the inner wall of the limit groove 19 blocks the limit block 20, and the ring plate 18 is limited, thereby realizing the installation and disassembly of the ring plate 18.
