Description

Technical Field

[0001] The utility model relates to the technical field of leak detector components, in particular to a fluorine oil temperature control mechanism for a fluorine oil leak detection system. Background Art

[0002] The fluorine oil leak test is used to detect the sealing of the product. The product to be tested is first placed in light fluorine oil and pressurized. If the product has a leak, the light fluorine oil will enter the product from the leak point. The product is then placed in heated heavy fluorine oil. If there is a leak, the light fluorine oil will vaporize and form bubbles from the leak, thereby determining whether the product is leaking.

[0003] At present, when the fluorine oil leak detection test device is used, the fluorine oil needs to be heated to keep the working temperature of the fluorine oil at 125 ℃±5 ℃. In this process, a fluorine oil temperature control mechanism needs to be used. However, the previous generation of fluorine oil temperature control mechanism has the following shortcomings in actual use: it uses a single heating source to heat and keep the fluorine oil warm, which causes the initial heating process of the fluorine oil to be relatively linear, and it needs to be heated for a period of time before subsequent leak detection tests can be performed. This causes the initial debugging operation of the fluorine oil leak detection device to be time-consuming, affecting the actual test and use of the fluorine oil leak detection.

[0004] In view of this, it is particularly important to design and manufacture a fluorine oil temperature control mechanism that can improve the initial heating efficiency of fluorine oil and shorten the initial debugging time of fluorine oil leak detection device, and apply it in the fluorine oil leak detection system. Utility Model Content

[0005] The utility model aims to solve the problem that the early heating efficiency of the traditional fluorine oil temperature control mechanism is low, resulting in a long time-consuming early debugging operation of the fluorine oil leakage detection system, and proposes a fluorine oil temperature control mechanism for a fluorine oil leakage detection system.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A fluorine oil temperature control mechanism for a fluorine oil leak detection system comprises a main box, a front cover fixed at the front end of the main box, a plurality of first heating resistors installed at the top of the inner side of the main box, a PT100 temperature sensor installed at the middle of the left end of the main box, and a controller installed at the front end of the front cover; a sub-box connected to both ends of the main box is fixedly connected to the lower end of the main box, and an auxiliary heating mechanism is arranged on the sub-box to assist the fluorine oil in the main box to heat up to the required use temperature.

[0008] As a further description of the above technical solution:

[0009] The auxiliary heating mechanism includes a driving motor installed in the middle of the left end of the auxiliary box, a spiral blade installed at the right end of the driving motor and located inside the auxiliary box, and a plurality of second heating resistors installed equidistantly inside the auxiliary box and located on the right side of the spiral blade.

[0010] As a further description of the above technical solution:

[0011] The upper end of the main box body is connected with a liquid inlet pipe, and the right end of the auxiliary box body is connected with a liquid discharge pipe.

[0012] As a further description of the above technical solution:

[0013] A filter part for solid-liquid separation during the fluorine oil inlet process is arranged between the front cover and the main box body and below the liquid inlet pipe.

[0014] As a further description of the above technical solution:

[0015] The filter part includes a slot opened at the front end of the front cover and located below the liquid inlet pipe, two guide brackets installed between the main box body and the front cover and facing the slot, a filter screen movably installed between the slot and the two guide brackets, and leakage holes equidistantly opened at the lower end of the filter screen.

[0016] As a further description of the above technical solution:

[0017] An outer spiral disk is rotatably mounted at the front end of the filter screen, a knob is fixedly connected to the front end of the outer spiral disk, and the front end of the front cover is located outside the outer spiral disk and is fixedly connected to an inner screw seat corresponding to the outer spiral disk.

[0018] As a further description of the above technical solution:

[0019] Both sides of the lower end of the main box body are fixedly connected with mounting frames in an L-shaped structure, and mounting holes are opened on the horizontal ends of the mounting frames.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0021] 1. In the utility model, the original temperature control mechanism is scientifically and rationally improved, and a sub-box, a driving motor, a spiral blade and a second heating resistor are arranged on the main box. During the process of the first heating resistor in the main box heating the fluorine oil, the driving motor and the second heating resistor on the sub-box can be controlled to work synchronously. The operation of the driving motor can drive the spiral blade to rotate, so that the fluorine oil circulates between the main box and the sub-box. At the same time, the second heating resistor in the sub-box can perform contact heating treatment on the circulating fluorine oil. This structure can perform auxiliary heating treatment on the fluorine oil in the early stage of heating the fluorine oil, effectively improving the rate of the early stage of heating the fluorine oil, reducing the time-consuming early debugging operation of the fluorine oil leak detection device, thereby improving the efficiency and convenience of the actual test of the fluorine oil leak detection.

[0022] 2. In the utility model, a filter screen, an outer spiral disk and an inner screw seat are arranged between the original main box body, the front cover and the liquid inlet pipe, so that fluorine oil can enter the main box body through the liquid inlet pipe, and the filter screen can filter the fluorine oil. The filtered impurities will be concentrated and stored in the filter screen. When the outer spiral disk is screwed out of the inner screw seat, the filter screen can be pulled out of the main box body. This structure can filter the fluorine oil entering the main box body, which can reduce the circulation of solid impurities entering the temperature control mechanism and the leak detection pipeline, and at the same time can realize the tool-free discharge operation of the filter residue, thereby improving the working stability of the temperature control mechanism and the convenience of operation.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-3 The utility model provides a technical solution: a fluorine oil temperature control mechanism for a fluorine oil leakage detection system, comprising a main box body 1, a front cover 101 fixed at the front end of the main box body 1, a plurality of first heating resistors 4 installed at the top of the inner side of the main box body 1, a PT100 temperature sensor 5 installed at the middle of the left end of the main box body 1 and a controller 9 installed at the front end of the front cover 101, a sub-box body 6 connected to both ends of the main box body 1 is fixedly connected to the lower end of the main box body 1, and an auxiliary heating mechanism is arranged on the sub-box body 6 to assist the fluorine oil in the main box body 1 to heat up to meet the use temperature requirements.

[0030] Specifically, Figure 1-3 As shown, the auxiliary heating mechanism includes a driving motor 7 installed in the middle of the left end of the auxiliary box 6, a spiral blade 701 installed at the right end of the driving motor 7 and located on the inner side of the auxiliary box 6, and a plurality of second heating resistors 10 equidistantly installed inside the auxiliary box 6 and located on the right side of the spiral blade 701. When the fluorine oil is heated in the early stage, the second heating resistor 10 can work synchronously with the first heating resistor 4 to perform multi-directional synchronous heating operations on the fluorine oil, which can accelerate the heating operation of the fluorine oil. When the temperature of the fluorine oil reaches the working temperature, the second heating resistor 10 can stop working, and the first heating resistor 4 continues to work to perform heat preservation and heating treatment on the fluorine oil, keeping the fluorine oil continuously within the working temperature range. At the same time, when the driving motor 7 drives the spiral blade 701 to rotate, a circulating liquid flow can be generated between the main box 1 and the auxiliary box 6, which can accelerate the heat exchange treatment of the fluorine oil, thereby improving the heating effect of the fluorine oil and avoiding the occurrence of uneven heating during the heating process of the fluorine oil.

[0031] Specifically, Figure 1-3 As shown, the upper end of the main box body 1 is connected to a liquid inlet pipe 2, the right end of the auxiliary box body 6 is connected to a liquid discharge pipe 3, and a filter part for solid-liquid separation operation during the liquid entry of fluorine oil is provided between the front cover 101 and the main box body 1 and below the liquid inlet pipe 2. The filter part includes a slot 102 opened at the front end of the front cover 101 and located below the liquid inlet pipe 2, two guide brackets 106 installed between the main box body 1 and the front cover 101 and facing the slot 102, a filter screen 802 movably installed between the slot 102 and the two guide brackets 106, and leakage holes 803 equidistantly opened at the lower end of the filter screen 802.

[0032] At the same time, the front end of the filter screen 802 is rotatably installed with an outer spiral disk 8, and the front end of the outer spiral disk 8 is fixedly connected with a knob 801, which is convenient for the operator to hold and rotate the outer spiral disk 8 with his hands. The front end of the front cover 101 is located on the outside of the outer spiral disk 8 and is fixedly connected with an inner screw seat 103 corresponding to the outer spiral disk 8. When the outer spiral disk 8 is screwed into the inner screw seat 103 through threads, the filter screen 802 can be sealed and installed between the main box body 1 and the front cover 101.

[0033] Specifically, Figure 1-3 As shown, both sides of the lower end of the main box body 1 are fixedly connected with a mounting frame 104 in the shape of an L-shaped structure, and a mounting hole 105 is opened on the horizontal end of the mounting frame 104. The arrangement of the mounting frame 104 and the mounting hole 105 facilitates the main box body 1 to be installed and fixed to the fixed station of the fluorine oil leakage detection device by fasteners.

[0034] Working principle: When in use, fluorine oil can enter between the main box body 1 and the auxiliary box body 6 through the liquid inlet pipe 2, and at the same time, the fluorine oil can be discharged from the main box body 1 and the auxiliary box body 6 through the liquid discharge pipe 3. When performing the initial heating operation of the fluorine oil, the operator can operate the controller 9 to control the first heating resistor 4, the drive motor 7 and the second heating resistor 10 to be powered on. The first heating resistor 4 can perform contact heating treatment on the fluorine oil inside the main box body 1, and the drive motor 7 can drive the spiral blade 701 to rotate, so that a circulating liquid path is generated between the main box body 1 and the auxiliary box body 6, which can accelerate the heating of the fluorine oil. The effect can make the fluorine oil be heated more evenly. At the same time, the second heating resistor 10 can perform contact heating treatment on the fluorine oil inside the auxiliary box 6, thereby improving the efficiency and effect of the initial heating of the fluorine oil. During this process, the PT100 temperature sensor 5 can collect the temperature of the fluorine oil in real time, and transmit the fluorine oil temperature data to the controller 9 for calculation, analysis and comparison processing. When the collected fluorine oil temperature reaches the working temperature, the controller 9 will control the drive motor 7 and the second heating resistor 10 to stop working, and the first heating resistor 4 will perform insulation heating treatment on the fluorine oil.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
