Description

Technical Field

[0001] The invention relates to the technical field of leak detection tooling, in particular to a leak detection tooling assembly for leak detection of left and right water chambers of a radiator. Background Art

[0002] Currently, the radiator is composed of three parts: an inlet chamber, an outlet chamber, a main plate and a radiator core. The coolant flows in the radiator core and the air passes outside the radiator core. The hot coolant cools down due to the heat dissipation to the air, and the cold air heats up due to absorbing the heat dissipated by the coolant, so the radiator is a heat exchanger.

[0003] The traditional method of detecting leaks in the radiator water chamber is to pour leak detection liquid into the radiator water chamber, and use a magnifying glass to carefully check whether there are water marks or signs of leakage in and out of the water chamber pipes around the radiator. If a leak is detected, the radiator needs to be repaired or replaced.

[0004] However, this method mainly detects leaks at the inlet and outlet pipes of the water chamber, and it is difficult to effectively detect the interface of the inlet and outlet pipes of the water chamber. The leak detection liquid will flow out directly from the inlet and outlet pipes of the water chamber, and it is impossible to detect the internal blockage of the interface of the inlet and outlet pipes of the water chamber. Especially when the inner holes of the inlet and outlet pipes of the water chamber are not penetrated, so that the inlet and outlet pipes are isolated from the inner cavity of the water chamber, this method of filling the interior with leak detection liquid cannot effectively detect, resulting in false detection.

[0005] To this end, we have designed a radiator left and right water chamber leak detection tooling assembly that can prevent false detection. Summary of the invention

[0006] The purpose of the present invention is to provide a leak detection tooling assembly for detecting leaks in the left and right water chambers of a radiator, so as to solve the problem in the above background technology that the internal blockage at the inlet and outlet pipe interfaces of the water chamber cannot be accurately detected.

[0010] The water outlet connecting pipe fitting is provided with a gas blocking leak detection tool for detecting internal blockage at the water outlet pipe interface, and the gas blocking leak detection tool comprises a second base, a second anti-error detection pin, a second eccentric wheel and a second sealing ring for sealing the water outlet pipe interface, wherein the second eccentric wheel is rotatably connected to the second base, the second sealing ring is sleeved on the second base and is located above the second anti-error detection pin; the second anti-error detection pin is integrally formed with the second base.

[0012] Preferably, the air intake leak detection tool further comprises:

[0013] A first gasket, wherein the first gasket is sleeved on the first gasket, and the first gasket is tightly attached to the top of the first sealing ring;

[0014] A second gasket, wherein the second gasket is sleeved on the first base and is tightly attached to the bottom of the first sealing ring;

[0015] A first nut is threadedly connected to the first base, and a top of the first nut is tightly against a bottom of the second washer.

[0016] Preferably, the air intake connector is inserted at the opening of the air intake passage.

[0017] Preferably, a first mounting hole is provided on the side wall of the first eccentric wheel, and a first handle is connected to the first eccentric wheel.

[0018] Preferably, the first handle is fixedly connected to one end thereof close to the first eccentric wheel with a first cylindrical block, an outer wall of the first cylindrical block is provided with a first threaded groove, and the first cylindrical block is threadedly connected to the first mounting hole through the first threaded groove.

[0019] Preferably, a second through hole is formed on the second eccentric wheel, a rectangular hole is formed on the second base, and the second through hole is opposite to the rectangular hole; the gas plugging and leak detection tool also includes: a second movable pin shaft, and the second movable pin shaft is inserted in the rectangular hole and the second through hole.

[0023] The first aspect of the present invention is to provide a radiator left and right water chamber leak detection tooling assembly capable of preventing misdetection, which has the following beneficial effects:

[0024] 1. The leak detection tooling assembly for the left and right water chambers of the radiator is used to insert the first error-proofing detection pin on the air intake leak detection tooling and the second error-proofing detection pin on the air blocking leak detection tooling into the interface of the water inlet pipe and the water outlet pipe respectively. If the interface of the water inlet pipe and the water outlet pipe is blocked (for example, due to the processing technology, there is still a part of the film inside the pipe, so that the channel in the pipe is partially or completely blocked), due to the existence of the blockage, the first error-proofing detection pin and the second error-proofing detection pin cannot be fully inserted. At this time, the first sealing ring and the second sealing ring cannot completely seal the inner wall of the water inlet connecting pipe and the water outlet connecting pipe (that is, the sealing ring cannot cooperate with the corresponding opening on the inner wall to seal). At this time, when the detection is carried out through ventilation, the dry detector will display a large leak alarm when detecting here, thereby realizing the detection of the internal blockage at the interface of the water inlet and outlet pipes of the water chamber body.

[0025] 2. The leak detection tooling assembly for the left and right water chambers of the radiator is used to detect the air tightness of the water chamber body by setting the air intake leak detection tooling and the air blocking leak detection tooling. During the detection, the air intake leak detection tooling is first inserted into the water inlet connecting pipe fitting at the water inlet pipe interface, and then the air blocking leak detection tooling is inserted into the water outlet connecting pipe fitting at the water outlet pipe interface. The air is ventilated into the water chamber body through the air intake channel on the air intake leak detection tooling. Finally, the water inlet and outlet interfaces of the water chamber body are tested for internal blocking with the help of a dry detector. Of course, the air tightness detection of various positions of the water chamber body can also be realized. BRIEF DESCRIPTION OF THE DRAWINGS

The gas plugging and leak detection tool 7 includes a second base 703, a second error-proofing detection pin 707, a second eccentric wheel 701, and a second sealing ring 705 for sealing the interface of the water outlet pipe 5, wherein the second eccentric wheel 701 is rotatably connected to the second base 703, the second sealing ring 705 is sleeved on the second base 703, and is located above the second error-proofing detection pin 707; the second error-proofing detection pin 707 is integrally formed with the second base 703.

[0045] By setting up an air intake leak detection tool 4 and an air blocking leak detection tool 7, the water chamber body 1 is tested for internal blockage. During the test, the air intake leak detection tool 4 is first inserted into the water inlet connecting pipe 3 at the interface of the water inlet pipe 2, and then the air blocking leak detection tool 7 is inserted into the water outlet connecting pipe 6 at the interface of the water outlet pipe 5.

Finally, the water chamber body 1 and the interface are tested for internal blockage with the help of a dry detector. If the inner holes of the inlet and outlet pipes of the water chamber body 1 are not penetrated and isolated from the inner cavity of the water chamber, the tool is The error-proofing detection pin cannot be fully inserted into the water inlet pipe 2 and the water outlet pipe 5, and the sealing ring on the tooling cannot completely and thoroughly seal the inner wall of the inlet and outlet water connecting pipes. During the ventilation inspection, the dry detector will display a large leak alarm and judge that the leak detection is unqualified, thereby playing a role in leak detection and error prevention. It should be noted that the dry detector is a gas tightness detector, also known as a leak detector, airtightness instrument, leakage detector, and leak tester. The instrument is composed of high-precision sensor components and can detect micro-leaks in the product being tested. The dry detector is a prior art and will not be elaborated on here.

[0046] Example 1: Please refer to Figure 2 , Figure 3 and Figure 4 In the gas leak detection tool 4 of the present invention, the first eccentric wheel 401 and the first base 403 are both provided with a first through hole, and the axes of the plurality of first through holes are opposite to each other. The air intake leak detection tool 4 also includes a first movable pin shaft 402, which is inserted through the first through hole, and both ends of the first movable pin shaft 402 are provided with elastic limiting plates of different sizes.

The first gasket 404 is sleeved on the first gasket 404, and the first gasket 404 is in close contact with the top of the first sealing ring 405; the air intake leak detection tool 4 also includes a second gasket 406, the second gasket 406 is sleeved on the first base 403, and the second gasket 406 is in close contact with the bottom of the first sealing ring 405; the air intake leak detection tool 4 also includes a first nut 407, a thread groove is provided on the bottom side wall of the first base 403, the first nut 407 is threadedly connected to the first base 403, and the top of the first nut 407 is in close contact with the bottom of the second gasket 406;

[0047] When installing the air intake leak detection tool 4, the second gasket 406, the first sealing ring 405 and the first gasket 404 are sequentially mounted on the first base 403. The staff uses a tool to rotate the first nut 407 to threadably connect it with the first base 403 through the threaded groove provided on the first base 403, thereby fixing the second gasket 406, the first sealing ring 405 and the first gasket 404 on the first base 403 to achieve the installation of the air intake leak detection tool 4.

[0048] The air intake connector 8 is inserted at the opening of the air intake passage 411, a first mounting hole 410 is provided on the side wall of the first eccentric wheel 401, a first handle 400 is connected to the first eccentric wheel 401, and a first cylindrical block 409 is fixedly connected to one end of the first handle 400 close to the first eccentric wheel 401, a first threaded groove is provided on the outer wall of the first cylindrical block 409, and the first cylindrical block 409 is threadedly connected to the first mounting hole 410 through the first threaded groove.

[0049] When in use, the air intake leak detection tool 4 is inserted into the water inlet connecting pipe 3 at the interface of the water inlet pipe 2. If the water inlet connecting pipe 3 at the interface of the water inlet pipe 2 is blocked, the first error-proofing detection pin 408 of the air intake leak detection tool 4 cannot be fully inserted into the inner cavity of the pipeline. At this time, the first sealing ring 405 cannot completely seal the inner wall of the water inlet connecting pipe 3. During the ventilation test, the dry detector will display a large leak alarm when detecting here, thereby realizing the detection of blockage in the water inlet connecting pipe 3 at the interface of the water inlet pipe 2 of the water chamber body 1.

At the same time, the second through hole on the second eccentric wheel 701 is positioned opposite to the rectangular hole on the second base 703, and finally the second movable pin 702 is inserted into the second through hole and the rectangular hole. The staff uses tools to rotate the two second nuts 710 and threadedly connect them with the second movable pin 702 through the threaded groove provided on the second movable pin 702, so that the second eccentric wheel 701 is fixed to the second base 703, thereby fixing the second sealing ring 705 and the third gasket 704 on the second base 703, and realizing the installation of the gas plugging and leak detection tool 7.

[0051] A second mounting hole 709 is provided on the side wall of the second eccentric wheel 701, and a second handle 700 is connected to the second eccentric wheel 701. An end of the second handle 700 close to the second eccentric wheel 701 is fixedly connected to a second cylindrical block 708. A second threaded groove is provided on the outer wall of the second cylindrical block 708, and the second cylindrical block 708 is threadedly connected to the second mounting hole 709 via the second threaded groove. The second handle 700 is provided to facilitate the staff to take and place the gas blocking leak detection tool 7.

[0052] When in use, insert the gas blocking leak detection tool 7 into the water outlet connecting pipe fitting 6 at the interface of the water outlet pipe 5. If the water outlet connecting pipe fitting 6 at the interface of the water outlet pipe 5 is blocked, the second error-proofing detection pin 707 of the gas blocking leak detection tool 7 cannot be fully inserted into the inner cavity of the pipeline. At this time, the second sealing ring 705 cannot completely seal the inner wall of the water outlet connecting pipe fitting 6. During the ventilation test, the dry detector will display a large leak alarm when detecting this point, thereby realizing the detection of the sealing and internal blockage of the water outlet connecting pipe fitting 6 at the interface of the water outlet pipe 5 of the water chamber body 1.

[0053] Working principle: first insert the air intake leak detection tool 4 into the water intake connection pipe 3 at the interface of the water inlet pipe 2, then insert the air blocking leak detection tool 7 into the water outlet connection pipe 6 at the interface of the water outlet pipe 5, then insert the air intake joint 8 into the air intake channel 411 on the air intake leak detection tool 4, finally ventilate the water inlet pipe 2 and the water outlet pipe 5 on the water chamber body 1 through the air intake joint 8 and the air intake channel 411, and use the dry detector to perform internal blockage detection on the water inlet pipe 2, the water outlet pipe 5 and the water inlet connection pipe 3 and the water outlet connection pipe 6 at the interface of the water chamber body 1;

[0054] If the water inlet connecting pipe 3 at the interface of the water inlet pipe 2 is blocked, the first error-proofing detection pin 408 of the air inlet leak detection tool 4 cannot be fully inserted into the inner cavity of the pipeline. At this time, the first sealing ring 405 cannot completely seal the inner wall of the water inlet connecting pipe 3, and the gas entering the water chamber body 1 will leak from the gap between the first sealing ring 405 that is not completely sealed and the water inlet connecting pipe 3. The dry detector will display a major leak alarm when detecting this place;

[0055] If the water outlet connecting pipe 6 at the interface of the water outlet pipe 5 is blocked, the second error-proofing detection pin 707 of the gas leak detection tool 7 cannot be fully inserted into the inner cavity of the pipeline. At this time, the second sealing ring 705 cannot completely seal the inner wall of the water outlet connecting pipe 6. The gas entering the water chamber body 1 will leak from the gap between the second sealing ring 705 that is not completely sealed and the water outlet connecting pipe 6. The dry detector will display a large leak alarm when detecting here.
