Description

Technical Field

[0001] The utility model relates to a pressure difference measurement technology, in particular to a mechatronics differential pressure gauge. Background Art

[0002] The differential pressure gauge, also known as the differential pressure gauge, is one of the important components of the mechatronics system. By measuring the pressure difference of the flowing medium in the mechatronics system, the differential pressure gauge can promptly detect whether the pressure difference of the flowing medium is abnormal, thus avoiding safety accidents caused by the abnormal pressure difference and untimely treatment.

[0003] The patent document with publication number "CN219830172U" discloses "a magnetic flip column differential pressure gauge, comprising a protective shell, a meter body and a cover body, a placement groove being provided on one side of the protective shell, and a positioning groove being provided at the bottom of the placement groove; a protective shell is provided to cooperate with the cover body, so that the meter body is placed in a safe cover body, which is beneficial to protecting the meter body, reducing the erosion of dust and moisture on the meter body, and thus extending the service life of the meter body." Although "it is beneficial to protecting the meter body, reducing the erosion of dust and moisture on the meter body, and thus extending the service life of the meter body," the temperature change of the differential pressure gauge will affect the measurement result during the pressure difference measurement. Although the protective shell can protect the meter body, it cannot adjust the ambient temperature of the meter body. Therefore, when the external temperature changes significantly, the pressure difference measurement result will be erroneous. Utility Model Content

[0023] like Figure 1-Figure 3 As shown, a mechatronic differential pressure gauge includes a protective box 1, a differential pressure gauge body 2 is arranged inside the protective box 1, a metal conduction plate 13 is arranged inside the protective box 1 and outside the differential pressure gauge body 2, and the metal conduction plate 13 is fixedly connected to the protective box 1, a liquid cavity 14 is provided between the interior of the protective box 1 and the metal conduction plate 13, a delivery pipe 9 is fixedly installed on the lower end of both sides of the protective box 1, a temperature probe 8 is fixedly installed in the center of the top of the protective box 1, an electric heating rod 7 is fixedly installed on one side of the top of the protective box 1, and a cooling rod 15 is fixedly installed on the other side of the top of the protective box 1.

[0024] Specifically, when using an electromechanical integrated differential pressure gauge to measure the pressure difference, water as a temperature regulating medium is input into the liquid cavity 14 through the delivery pipe 9, and the temperature of the water is monitored by the temperature probe 8. At the same time, the water is heated by starting the electric heating rod 7 and cooled by starting the cooling rod 15. The temperature of the water is adjusted by utilizing the mutual cooperation between the electric heating rod 7 and the cooling rod 15, and the temperature is transferred to the differential pressure gauge body 2 through the metal conduction plate 13, so as to maintain the ambient temperature of the differential pressure gauge body 2 when measuring the pressure difference, and avoid the temperature change from affecting the measurement result of the differential pressure gauge body 2.

[0025] A control panel 6 is fixedly installed on the upper end of one side of the protective box 1, and a main board is fixedly installed inside the box body of the protective box 1 and behind the differential pressure gauge body 2. The main board, the control panel 6, the heating rod 7, the cooling rod 15 and the temperature probe 8 are electrically connected, and the lower ends of the heating rod 7, the cooling rod 15 and the temperature probe 8 are all located in the liquid cavity 14.

[0026] Specifically, the temperature parameter range is set by the control panel 6, the temperature probe 8 monitors the temperature of the water in the liquid cavity 14 in real time and transmits it back to the main board, and then the main board controls the electric heating rod 7 and the cooling rod 15 to adjust the temperature of the water, so that the temperature of the water is stabilized within the set temperature parameter range, which is convenient for reasonably adjusting the ambient temperature of the differential pressure gauge body 2 according to the medium measured by the differential pressure gauge body 2, thereby reducing the impact of temperature changes on the measurement results of the differential pressure gauge body 2.

[0027] A gauge slot 11 is provided in the center of the front side of the protection box 1 , and the differential pressure gauge body 2 is connected to the protection box 1 via the gauge slot 11 .

[0028] A docking groove 12 is provided through the front surface of the protection box 1 and at the bottom of the surface groove 11 . A pressing block 3 is provided inside the docking groove 12 . The pressing block 3 is engaged with the protection box 1 through the docking groove 12 .

[0029] Specifically, after placing the differential pressure gauge body 2 in the gauge groove 11, the pressure block 3 is pressed into the docking groove 12, so that the differential pressure gauge body 2 can be pressed tightly by the pressure block 3 to prevent the differential pressure gauge body 2 from shaking after docking with the protective box 1, resulting in errors when measuring the pressure difference.

[0030] A card slot 4 is provided through the top of the protection box 1 and at the front end of the surface slot 11 . A card plate 5 is provided inside the card slot 4 . The card plate 5 is connected to the protection box 1 through the card slot 4 .

[0031] An observation window 10 is fixedly installed in the center of the front and rear ends of the clamping plate 5.

[0032] Specifically, after pressing the pressure block 3 into the docking groove 12, the card plate 5 is inserted into the card slot 4. The card plate 5 is used to limit the pressure block 3 to prevent the pressure block 3 from detaching from the docking groove 12. The card plate 5 is used to compress the pressure block 3 and the differential pressure gauge body 2 to further improve the stability of the differential pressure gauge body 2. At the same time, the differential pressure gauge body 2 is wrapped by the card plate 5, the observation window 10 and the protective box 1 to protect the differential pressure gauge body 2, reduce the erosion of dust and moisture on the differential pressure gauge body 2, and extend the service life of the differential pressure gauge body 2.

[0033] It should be noted that the present invention is an electromechanical integrated differential pressure gauge. When in use, first, the differential pressure gauge body 2 is placed in the gauge slot 11, and then the pressure block 3 is pressed into the docking slot 12. After that, the card plate 5 is inserted into the card slot 4. The card plate 5 limits the pressure block 3 to prevent the pressure block 3 from escaping from the docking slot 12. The card plate 5 is used to press the pressure block 3 and the differential pressure gauge body 2. It is convenient to press the differential pressure gauge body 2 by the pressure block 3 and the card plate 5, so as to prevent the differential pressure gauge body 2 from shaking after docking with the protective box 1, and to prevent errors in measuring the pressure difference.

[0034] After completing the installation of the differential pressure gauge body 2, during the pressure difference measurement process, observe the displayed value of the differential pressure gauge body 2 through the observation window 10, set the temperature parameter range through the control panel 6, input water as a temperature regulating medium into the liquid cavity 14 through the delivery pipe 9, and monitor the temperature of the water through the temperature probe 8. At the same time, the water is heated by starting the electric heating rod 7 and cooled by starting the cooling rod 15. The temperature of the water is adjusted by utilizing the mutual cooperation between the electric heating rod 7 and the cooling rod 15, and the temperature is transferred to the differential pressure gauge body 2 through the metal conduction plate 13, so as to maintain the ambient temperature of the differential pressure gauge body 2 when performing the pressure difference measurement, and reasonably adjust the ambient temperature of the differential pressure gauge body 2 according to the medium measured by the differential pressure gauge body 2, thereby reducing the influence of temperature changes on the measurement results of the differential pressure gauge body 2.
