[0002] As the name suggests, a liquid level gauge is a device used to measure the liquid level in a large container. It is commonly used in the field of boiler level monitoring to ensure that there is always water in the boiler to prevent accidents. As the application places become wider and wider, the working modes of the liquid level gauge are also more and more. At the same time, the quality requirements for the liquid level gauge are also getting higher and higher. In order to ensure that the liquid level gauge meets the requirements, the liquid level gauge needs to be sealed and tested. At this time, a sealing detection device is required.
[0003] Existing detection devices have deficiencies in multi-station detection and operational flexibility, and the overall detection efficiency needs to be improved. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the present invention are:
[0012] 1. The utility model is provided with two detection chambers, which can simultaneously detect two liquid level gauges or perform detection operations on one liquid level gauge separately. The two detection chambers can be controlled independently, and thus can be flexibly selected according to actual needs. The utility model has strong flexibility in use. Since the two detection tubes can be rotatably installed at the outlet end of the second air guide tube, the corresponding detection tubes can be independently rotated to adjust the distance between the two detection tube ports, thereby effectively adapting to the detection operation of liquid level gauges of different sizes and having strong practicality.

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0018] See also Figure 1-2, an embodiment of the present invention provides: a sealing detection device for liquid level gauge production, comprising a detection box 1, an inner partition 2 is provided at the middle position inside the detection box 1, a detection chamber is provided on both sides of the inner partition 2, and a box door 3 is hingedly connected to the opening of each detection chamber, and two second air ducts 11 are fixedly connected to the back of the detection box 1, and the two second air ducts 11 correspond to the two detection chambers respectively, and a detection tube 7 is rotatably installed at the two air outlet ports of the second air duct 11, and an observation window 4 is provided on the outer surface of the box door 3. By setting up two detection chambers, two liquid level gauges can be detected at the same time, or one liquid level gauge can be detected separately, and the two detection chambers can be controlled independently, so that they can be flexibly selected according to actual needs, and have strong flexibility in use. Since the two detection tubes 7 can be rotatably installed at the air outlet ends of the second air duct 11, the corresponding detection tubes 7 can be independently rotated to adjust the distance between the ports of the two detection tubes 7, so that it can effectively adapt to the detection operation of liquid level gauges of different sizes, and has strong practicality.
[0019] Furthermore, a mounting hole is provided on the upper end surface of the two detection chambers inside the detection box 1, and an air pressure sensor 5 (PT500-501) is installed inside each mounting hole. Two pressure alarms 6 are fixedly installed on the upper surface of the detection box 1. The two pressure alarms 6 correspond to two air pressure sensors 5 respectively. The air pressure sensor 5 is electrically connected to the pressure alarm 6. The air pressure sensor 5 can be used to monitor the air pressure inside the detection chamber and transmit the monitored value to the inside of the pressure alarm 6. When the liquid level gauge leaks, the air pressure value inside the detection chamber will increase. At this time, it exceeds the safety range value of the pressure alarm 6. The pressure alarm 6 will sound an alarm to remind the staff that the liquid level gauge is leaking.
[0020] Furthermore, a high-pressure air pump 8 is fixedly installed on the upper surface of the detection box 1, and a first air duct 9 is fixedly installed on the air outlet end of the high-pressure air pump 8. A communicating vessel 10 is installed in the pipeline of the first air duct 9. A mounting hole is provided on the outer surface of one side of the communicating vessel 10, and an electronic smoke generator 13 is fixedly installed inside the mounting hole. The first air duct 9 is provided with two air outlet ends, and the two air outlet ends are respectively connected to the air inlet ends of the two second air ducts 11. A solenoid valve 12 is installed near the two air outlet ports of the first air duct 9. Through the setting of the communicating vessel 10 and the electronic smoke generator 13, the electronic smoke generator 13 can be started during detection, and the produced smoke can be mixed with the air generated by the high-pressure air pump 8, and enter the interior of the liquid level gauge along the first air duct 9, the second air duct 11 and the detection tube 7. When the liquid level gauge leaks, the leakage location can be clearly and conveniently viewed, which greatly improves the detection efficiency.
[0021] Working principle: When in use, first install the device at the designated position, and then install the liquid level gauge to be detected at one end of the two detection tubes 7. During installation, the corresponding detection tube 7 can be rotated to adapt to the length of the liquid level gauge. After installation, close the box door 3 and lock it, then open the solenoid valve 12, and start the high-pressure air pump 8 and the electronic smoke generator 13. At this time, the electronic smoke generator 13 generates smoke that enters the interior of the communicating vessel 10. When the high-pressure gas generated by the high-pressure air pump 8 passes through the interior of the communicating vessel 10, the smoke mixes with the air and enters the liquid level gauge along the first air duct 9, the second air duct 11, and the detection tube 7. Inside, the air pressure sensor 5 is used to monitor the air pressure value inside the detection chamber in real time, and the monitored value is transmitted to the inside of the pressure alarm 6. When the liquid level gauge leaks, the air pressure value inside the detection chamber will increase. At this time, it exceeds the safety range value of the pressure alarm 6. The pressure alarm 6 will sound an alarm to remind the staff that the liquid level gauge is leaking. At this time, the staff can observe the corresponding liquid level gauge through the observation window 4 and check where the smoke gas overflows from the liquid level gauge, and then quickly find the leakage point of the liquid level gauge. Since the two solenoid valves 12 are independent of each other, the two detection chambers can be independently controlled.
