Description

Technical Field

[0001] This utility model relates to the field of pressure gauge calibration technology, and in particular to a portable manual pressure gauge calibration device suitable for field use. Background Technology

[0002] Pressure gauge calibration is crucial in industrial production. Its core purpose is to ensure the accuracy and precision of pressure gauges, thereby guaranteeing the safe and stable operation of production equipment, especially in industries such as power, oil and gas, and energy.

[0003] Currently, with the upgrading of calibration equipment, pressure gauge calibration is mostly completed using automatic calibration equipment. However, automatic calibration equipment has a drawback: it needs to be used in conjunction with an air compressor, and relevant personnel cannot bring the equipment into the site, or bringing the calibration equipment requires a certain amount of manpower and resources.

[0004] However, in industrial production, especially in the power industry, transmission lines are widely distributed, particularly in sparsely populated or harsh natural environments. These transmission lines require on-site equipment inspection by workers. This means that workers cannot efficiently complete pressure gauge calibration using existing automatic pressure gauge calibration equipment, and thus use the calibrated pressure gauges to perform equipment maintenance, resulting in low work efficiency.

This manual pressure gauge calibration device has a simple overall structure, small size, and is easy to carry. It is suitable for field use in industrial production environments and improves work efficiency.

[0041] like Figures 1-5 As shown, it illustrates a specific embodiment of this utility model:

[0042] Example 1

[0043] A portable manual pressure gauge calibration device suitable for field use includes a carrying case 1, a buffer pad 2, and a manual pressure gauge calibration component 3. The buffer pad 2 is placed inside the carrying case 1, and the manual pressure gauge calibration component 3 is placed inside the buffer pad 2.

[0044] In this embodiment, as Figure 1 As shown, when carrying this calibration device, the manual pressure gauge calibration component 3 is placed inside the buffer pad 2 in the carrying case 1. The buffer pad 2 prevents vibration during carrying, ensuring the calibration accuracy of the manual pressure gauge calibration component 3. At the same time, carrying it in the carrying case 1 is convenient and labor-saving. Overall, the calibration device has a simple structure, small size, and is easy to carry. It can be used in the field environment of industrial production, thereby improving the work efficiency of relevant personnel.

[0045] The manual pressure gauge calibration assembly 3 includes a calibration base 31, adjusting feet 32, a first pressure gauge mounting base 33, a second pressure gauge mounting base 34, a third pressure gauge mounting base 35, an oil cup 36, a pressure rod 37, a pressure adjustment disc 38, and a balancer 39. There are four adjusting feet 32, which are respectively installed at the four corners of the bottom surface of the calibration base 31. The first pressure gauge mounting base 33, the second pressure gauge mounting base 34, and the third pressure gauge mounting base 35 are fixedly installed on the left side of the upper surface of the calibration base 31. The oil cup 36 is fixedly installed on the right rear side of the upper surface of the calibration base 31. The pressure rod 37 is located in front of the oil cup 36. The pressure adjustment disc 38 is connected to the front of the calibration base 31. The balancer 39 is fixedly installed on the upper surface of the calibration base 31.

[0046] In this embodiment, as Figure 2 , Figure 4As shown, when using the manual pressure gauge teaching and research component 3 to calibrate the pressure gauge, first observe whether the calibration base 31 is in a horizontal state through the balancer 39, thereby checking the pressure gauge, ensuring calibration accuracy, and avoiding the influence of the calibration base 31 tilting on the calibration results. At the same time, the balancer 39 is visually inspected for easy identification. When the calibration base 31 tilts, adjust the four adjusting pads 32 under the calibration base 31 to ensure that the calibration base 31 is in a horizontal state.

[0047] In this embodiment, as Figure 2 , Figure 3 As shown, during calibration, one standard pressure gauge and two pressure gauges to be calibrated can be installed through the first pressure gauge mounting base 33, the second pressure gauge mounting base 34, and the third pressure gauge mounting base 35, enabling the calibration of two pressure gauges at once and improving the calibration efficiency. The calibrator applies pressure quickly by operating the pressure rod 37, and precisely adjusts the pressure value through the pressure adjustment disc 38 when the pressure approaches the calibration pressure value, achieving rapid calibration. The combination of rapid and precise pressure application further improves the calibration efficiency and ensures the calibration accuracy.

[0052] In this embodiment, as Figure 2 , Figure 3 As shown, the cup cylinder 361 and the cup lid 362 of the oil cup 36 are connected by threads, which facilitates the addition of insulating oil into the cup cylinder 361 during pressure gauge calibration. The threaded connection also makes it easy to connect and open the cup lid 362 to the cup cylinder 361, and avoids the possibility of the oil cup 36 tipping over and causing the insulating oil to leak out during calibration due to accidental operation. At the same time, a threaded adjustment knob 363 is connected above the cup lid 362 to facilitate the calibration personnel to connect the cup lid 362.

[0053] In this embodiment, the cup 361 made of transparent material makes it easy for the calibration personnel to observe the liquid level of the insulating oil inside the cup 361. With the setting of scale lines, the liquid level of the insulating oil can be accurately understood, which is intuitive and convenient. An oil outlet is provided at the lower part of the outer surface of the cup 361.

When transporting and carrying, the disc 382 can be detached to save space and facilitate use. At the same time, the ends of the pressure rod 37 and the rotating handle 383 are spherical structures 371, which facilitates operation by calibration personnel.
