Description

A kind of device for detecting leak tightness of inner water tank of vacuum-tube solar water heater
Technical field
The invention belongs to the generation of heat and utilize the field.
Background technology
The water tank that common solar vacuum-tube water heater uses comprises inner bag, heat-insulation layer, shell, water inlet pipe interface and rising pipe interface, inner bag is processed by corrosion resistant plate usually, owing in mechanical processing process, can cause certain damage to corrosion resistant plate, and inner bag in use contacts with water for a long time, particularly the joint that produces in some process belongs to the concentrated position of stress, be to use the easiest place that goes wrong in the process, the joint can occur and leak, have a strong impact on user's normal use.So, solar energy production producer in the manufacture process of inner bag except the elimination defective measure that cooperates some other necessity, often after the whole manufacturing of water tank is good, be placed in the water, whether the gas that applies certain pressure in the inner bag can leak gas to detect the inner bag joint, whether has defective.
But because the volume of water tank is bigger, operate relatively difficulty during detection, often cause omission, hide some dangers for for later use; And in actual production process, arrive the installing port that has offered water inlet pipe interface, rising pipe interface and vacuum heat collection pipe on the water tank that detects step, when pressurizeing detection, how when detecting, to avoid these interfaces to bring interference to detection, and prevent that gases at high pressure from first revealing and do not reach the purpose that detects inner water tank joint sealing from these interfaces, consistent is those skilled in the art's problem demanding prompt solutions.
Summary of the invention
The invention provides a kind of device for detecting leak tightness of inner water tank of vacuum-tube solar water heater, this device is simple to operate, the interference that can avoid omission and the minimizing enterprising waterpipe jointing of water tank and rising pipe interface that detection is caused, can be implemented in the sealing that detects inner bag under the elevated pressures condition, thereby guarantee that each tested water tank can both reach sealing requirements.
For achieving the above object, the present invention adopts following technological means:
This pick-up unit comprises fixedly chuck 1, movable chuck 2 and hold down gag 3 three parts, and wherein fixedly chuck 1 and movable chuck 2 all are the annular members that is fixed with reinforcement, and install relatively in the two axle center; Fixedly the shaft core position of chuck 1 is provided with sliding bearing 4, turning axle 5 passes sliding bearing 4 and is fixed on the support 6, support 6 is installed on two side plates that detect groove 7, the axle center of movable chuck 2 is provided with the fixed hub 8 of inner hollow, one section of threaded rod 9 with axle sleeve 8 flexible connections, the other end of threaded rod 9 pass be fixed on detect on groove 7 end plates, be provided with the sleeve 10 of the internal thread that matches with threaded rod after, connect with rotatable regulating wheel 11, drive threaded rod 9 by rotatable regulating wheel 11, can realize chucking and unclamp water tank 12 to be measured; Fixedly identical position is respectively equipped with mounting groove 13 on chuck 1 and movable chuck 2 circumference, establishes fastener 14 on the mounting groove 13, fastener 14 device 3 that is fixed and clamped; Fixedly the inner ring diameter of chuck 1 and movable chuck 2 is slightly less than the end cap diameter of water tank 12 to be measured, and the two ends of water tank 12 to be measured are fixed on fixedly in the chuck 1 and movable chuck 2.
When using this Equipment Inspection vacuum water tank 12 leak tightness of inner to be measured, in detecting groove 7, fill the detection liquid that adds antirust material earlier, with the water inlet pipe interface and the rising pipe sealing joint of water tank 12 to be measured, the installing port of vacuum heat collection pipe is sealed with rubber cork 21 again, prevented gas leakage;
The end that water tank 12 to be measured is provided with gas outlet 19 is stuck in the movable chuck 2 then, the other end sticks into fixedly in the chuck 1, and the thermal-collecting tube installing port of water tank 12 to be measured gone to and fixedly the mounting groove 13 that is provided with of chuck 1 and movable chuck 2 at same position, hold down gag is snapped in the mounting groove 13 then, and screw screw fastener 14, hold down gag 3 is fixing and push down rubber cork 21 on the vacuum tube thermal-collecting tube installing port;
From the gas outlet 19 of water tank 12 to be measured, feed gas afterwards, pressure meets country about the withstand voltage standard of vacuum pipe solar, close the air valve of gas outlet 19 then, rotation is chuck 1 and movable chuck 2 fixedly, observe water tank 12 shanks under water to be measured bubble whether occur, if there is not bubble, the sealing conformance with standard is described then.
