Detailed Description
The technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiment of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and all other embodiments obtained by those skilled in the art without any inventive work are within the scope of the present invention based on the embodiments of the present invention.
Example (b):
please refer to fig. 1-4, a heat exchanger tightness detection tool comprises a water tank 1, a plurality of water storage areas 2 are arranged inside the water tank 1, liquid is stored inside the water storage areas 2, the liquid can be preferably water for reducing the manufacturing cost, a heat exchange tube 11 is placed inside the liquid, a protective cover is installed outside the heat exchange tube 11, gas is filled between the protective cover and the heat exchange tube 11, and the gas pressure is higher than the normal pressure.
At the moment, when the sealing performance of the heat exchanger is detected, the heat exchange tube 11 is placed into the protective cover, then gas is filled into the heat exchange tube 11 until the pressure of the gas is higher than the normal pressure, then the protective cover is placed into the liquid in the water storage area 2, and the height of the liquid level is recorded;
when the sealing performance of the heat exchange tube 11 does not meet the standard, since the gas pressure inside the shield is greater than the gas pressure inside the heat exchange tube 11, the gas inside the shield gradually enters the inside of the heat exchange tube 11 to reduce the volume thereof, and when the volume of the shield is reduced, the liquid level of the liquid gradually decreases.
At this time, if the liquid level is unchanged, it indicates that the sealing performance of the heat exchange tube 11 is better;
if the liquid level is gradually reduced, the liquid level indicates that the tightness of any one or two of the heat exchange tube 11 and the protective cover is poor;
at this time, the protection cover on the outer side of the heat exchange tube 11 is replaced, and then the test is performed again, if the liquid level height is not changed, the sealing performance of the heat exchange tube 11 is good, and if the liquid level height is still gradually reduced, the sealing performance of the heat exchange tube 11 is poor.
Wherein, please refer to fig. 1, in order to observe the height of liquid level decline more clearly, the upside of water tank 1 is equipped with sealed lid 3, and in order to guarantee the leakproofness between water tank 1 and sealed lid 3, be provided with sealed pad between water tank 1 and the sealed lid 3, the upside fixedly connected with of sealed lid 3 and the observation pipe 4 of 2 looks adaptations of water storage district, and the outside of observation pipe 4 is provided with the height observation table, at this moment, because the cross section volume of observation pipe 4 is less than the cross section volume of water storage district 2 far away, after the volume of liquid reduces, the height that the inside liquid of observation pipe 4 descends is greater than the height that the inside liquid of water storage district 2 descends far away, thereby can more direct-viewing observe the height that liquid descends.
Simultaneously, in order to be more convenient carry out the water injection to observing 4 insides of pipe, the upside of sealed lid 3 still fixedly connected with the inlet tube 5 of 2 looks adaptations of water storage district, inlet tube 5 highly is higher than observing pipe 4, sealing valve 6 is installed to the lower extreme in the inlet tube 5 outside, when needs carry out the water injection to 2 insides of water storage district, open sealing valve 6, then carry out the water injection to 2 insides of water storage district through inlet tube 5, the water that spills over can get into the inside of observing pipe 4, close sealing valve 6 after the inside of observing pipe 4 is filled by liquid completely.
As shown in fig. 2-4, the protective cover includes an inner protective cover 8, the inner protective cover 8 is sleeved on the outer side of the heat exchange tube 11, a plurality of air holes 9 are formed on the periphery of the inner protective cover 8, an outer protective cover 7 is arranged on the outer side of the inner protective cover 8, and the outer protective cover 7 and the inner protective cover 8 are connected through a plurality of tension ribs 10, at this time, the inner protective cover 8 is sleeved on the outer side of the heat exchange tube 11, and then gas is filled into the outer protective cover 7, if the heat exchange tube 11 has poor sealing performance, the gas inside the outer protective cover 7 can enter the heat exchange tube 11 through the air holes 9.
Meanwhile, as shown in fig. 4, in order to more conveniently seal the protection cover and ensure the sealing performance of the protection cover after sealing, the protection outer cover 7 and the protection inner cover 8 are provided with openings at one ends, and the openings of the protection outer cover 7 and the protection inner cover 8 are sealed by hot melting.
When in use: when the tightness of the heat exchanger is detected, the heat exchange tube 11 is placed into the protective cover, then gas is filled into the heat exchange tube 11 until the pressure of the gas is higher than the normal pressure, then the protective cover is placed into the liquid in the water storage area 2, and the height of the liquid level is recorded;
when the sealability of the heat exchange pipe 11 is not standardized, since the gas pressure inside the shield is greater than the gas pressure inside the heat exchange pipe 11, the gas inside the shield gradually enters the inside of the heat exchange pipe 11, thereby reducing the volume thereof, and when the volume of the shield is reduced, the liquid level of the liquid gradually decreases.
At this time, if the liquid level is unchanged, it indicates that the sealing performance of the heat exchange tube 11 is better;
if the liquid level is gradually reduced, the liquid level indicates that the tightness of any one or two of the heat exchange tube 11 and the protective cover is poor;
at this time, the protective cover on the outer side of the heat exchange tube 11 is replaced, then the test is carried out again, if the liquid level height is not changed, the sealing performance of the heat exchange tube 11 is better, and if the liquid level height is still gradually reduced, the sealing performance of the heat exchange tube 11 is poorer;
simultaneously, will detect heat exchange tube 11 and the protection casing after accomplishing and take out directly to deposit, at this moment, protect heat exchange tube 11 through setting up the protection casing, can effectually protect heat exchange tube 11, reduce the probability that heat exchange tube 11 damaged because of the accident in storage and transportation, simultaneously, keep apart heat exchange tube 11 and liquid through setting up the protection casing, can effectually reduce heat exchange tube 11 and receive the injury of liquid in the testing process, reduce the damaged rate of device.
The above description is only the preferred embodiment of the present invention; the scope of the present invention is not limited thereto.
