Problems solved by technology

[0002] The water tank used by ordinary vacuum tube solar water heaters includes inner tank, insulation layer, outer shell, water inlet pipe interface and outlet pipe interface. Moreover, the liner is in contact with water for a long time during use, especially some joints produced during the processing process are stress-concentrated parts, which are the places where problems are most likely to occur during use, and water leakage will occur at the joints, which seriously affects the normal use of users.

Embodiment 1

[0036] like figure 1 , 2 , 3 and 4, the detection device includes three parts: a fixed chuck 1, a movable chuck 2, and a pressing device 3, wherein the fixed chuck 1 and the movable chuck 2 are ring-shaped members fixed with reinforcing ribs, The axes of the two are installed relative to each other; the axis of the fixed chuck 1 is provided with a sliding bearing 4, and the rotating shaft 5 passes through the sliding bearing of the axis of the fixed chuck 1 and is fixed on the bracket 6, and the bracket 6 is installed on the two sides of the detection groove 7. On the two side plates, the shaft center of the movable chuck 2 is provided with an internal hollow fixed shaft sleeve 8, and a section of the threaded rod 9 is flexibly connected with the shaft sleeve 8, and the other end passes through and is fixed on the detection groove 7 end plates, and is provided with internal threads. After the sleeve 10, it is connected with the rotatable adjustment wheel 11, and the threaded ...

Embodiment 2

[0041] like figure 1 , 2 , 3 and 5, the basic structure of the detection device is the same as that of embodiment 1, the difference is that the corresponding positions of the pressing device 3 are installed on the circumference of the fixed chuck 1 and the movable chuck 2, and other equally divided positions are provided with matching weights. Weight 15.

[0042] When using this equipment to detect the tightness of the inner liner of the vacuum water tank 12 to be tested, first fill the detection tank 7 with clean water, then seal the water inlet pipe interface and the water outlet pipe interface of the water tank 12 to be tested, and seal the installation port of the vacuum tube heat collector tube with rubber. Soft plug 21 is sealed, prevents air leakage;

[0043] Then the end of the water tank 12 to be tested is provided with the exhaust pipe 19 and is stuck in the movable chuck 2, and the other end is stuck in the fixed chuck 1, and the heat collector installation port o...

Embodiment 3

[0046] like figure 1 , 2 , 3 and 6, the basic structure of the detection device is the same as that of embodiment 1, the difference is that the rubber plug 21 that seals the installation port of the vacuum heat collecting tube is uniformly fixed on the compression device 3, and can tighten the device 14 and compression The end of the device is set as a card slot type that cooperates with each other, and the installation port of the vacuum heat collecting tube is sealed and pressed tightly, so as to realize the tightness of the inner tank under a relatively high pressure condition.

[0047] The end of the water tank 12 to be tested provided with the exhaust pipe 19 is clamped in the movable chuck 2, and the other end is clamped into the fixed chuck 1, and gas is introduced from the exhaust pipe 19 of the water tank 12 to be tested at a pressure of 0.06 Mpa, then close the air valve of the exhaust pipe 19, rotate the fixed chuck 1 and the movable chuck 2, observe whether bubble...

Abstract

The invention provides a device for detecting the leak tightness of an inner water tank of a vacuum-tube solar water heater, which belongs to the field of heat generation and application. The detecting device comprises a fixed chuck 1, a movable chuck 2 and a compaction device 3, wherein both the fixed chuck 1 and the movable chuck 2 are toroidal components which are fixedly provided with reinforcing ribs; the fixed chuck 1 is arranged on a detection slot 7, and the movable chuck 2 is fixed on an end plate of the detection slot 7; mounting slots 13 are respectively arranged at the same positions of the circumferences of the fixed chuck 1 and the movable chuck 2; and the mounting slot 13 is provided with a screw fastening device 14. The device is simple to operate, can avoid missed detection and interference on detection which is caused by water-inlet pipe joints and water-outlet pipe joints on the water tank, and detect the leak tightness of the inner water tank under the condition of higher pressure.

Description

technical field [0001] The invention belongs to the field of heat generation and utilization. Background technique [0002] The water tank used by ordinary vacuum tube solar water heaters includes inner tank, insulation layer, outer shell, water inlet pipe interface and outlet pipe interface. Moreover, the liner is in contact with water for a long time during use, especially some joints produced during the processing process are stress-concentrated parts, which are the places where problems are most likely to occur during use, and water leakage will occur at the joints, which seriously affects the normal use of users. Therefore, in addition to some other necessary measures to eliminate defects during the manufacturing process of the inner tank, the solar energy manufacturer often puts it in water after the water tank is manufactured as a whole, and applies a certain pressure of gas to the inner tank to test the inner tank. Whether there will be air leakage at the joint, whe...
