[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0028] like Figures 1-3 As shown, in one embodiment, a temperature and pressure detection instrument includes: a mounting connector 1 and a testing mechanism 2.
[0029] The mounting connector 1 is installed on the test end pipeline to connect the test core 2 and the pipeline, so that the working medium in the pipeline or equipment can flow into the test core 2 through the mounting connector 1; correspondingly, the test core 2 is installed on the mounting connector 1 to guide the working medium and simultaneously measure pressure and temperature.
[0030] It should be noted that the mounting connector 1 has a mounting cavity 11 inside, and the test mechanism 2 is detachably connected to the mounting connector 1 through the elastic element 12 and the connector 13.
[0031] Specifically, the connector 13 has a drainage cavity 131 inside, which can guide the working medium to flow along a predetermined path; while the elastic element 12 is sleeved on the outside of the connector 13, which can use its own elastic deformation characteristics to provide elastic pre-tightening force for the connection between the test core 2 and the mounting connector 1, which can enhance the stability of the connection, buffer the impact of vibration during operation, and facilitate the disassembly of the test core 2 for maintenance or replacement.
[0032] For example, the connector 13 can be a connecting sleeve, which can well adapt to the mounting cavity 11 of the mounting connector 1 and the connection requirements of the test mechanism 2; while the elastic element 12 can be a spring, which cooperates with the connecting sleeve to form a connection structure that ensures normal flow of the medium.
[0033] It should be explained in detail that the test mechanism 2 has a detection chamber 21 in the middle, and a guide chamber 22 is opened on one side of the detection chamber 21 at an upward angle. An elastic element 23 is installed on the top of the test mechanism 2, which can guide the working medium into the test mechanism 2 and the elastic element 23 in a reasonable path, thereby completing the measurement of temperature and pressure.
[0034] Furthermore, the middle of the test mechanism 2 is connected to a temperature pointer component 3 via a temperature sensing component 5. The temperature sensing component 5 can generate corresponding physical changes according to the temperature change, thereby driving the temperature pointer component 3 to move, and finally realizing the measurement and display of the temperature value. Correspondingly, on one side of the test mechanism 2, a pressure pointer component 4 is connected to a linkage amplification component 6. The linkage amplification component 6 will convert and amplify the pressure signal, driving the pressure pointer component 4 to accurately indicate the pressure value.
[0035] Specifically, a temperature sensing component 5 is provided inside the detection chamber 21, and the temperature sensing component 5 is sleeved on the bottom of the temperature pointer component 3, which allows the temperature sensing component 5 to more directly and sensitively sense the temperature change of the working medium inside the detection chamber 21; correspondingly, a linkage amplification component 6 is provided on one side of the top of the elastic element 23, and the linkage amplification component 6 is rotatably connected to the pressure pointer component 4, so that the pressure signal is converted by the linkage amplification component 6 and synchronously drives the pressure pointer component 4 to rotate.
[0036] For example, the temperature sensing component 5 can be a temperature-sensitive metal material with a certain shrinkage rate. When working media of different temperatures flow in, the temperature-sensitive bimetallic material will expand when heated and contract when cooled according to the thermal expansion and contraction characteristics of temperature. The magnitude of this physical deformation is related to the temperature change, which can then be converted into the power to drive the temperature pointer component 3 to rotate, thereby realizing the quantitative display of temperature. The linkage amplification component 6 is based on the lever principle. It is hinged to the pendulum through a pair of symmetrical connecting rods. By using the lever arm relationship, the small angle rotation is transmitted and amplified through the connecting rods to amplify the rotation effect of the pendulum, converting the small physical quantity change into a significant displacement display, which makes it convenient to read the measurement value.
[0037] Please continue reading. Figures 1-3 In this embodiment, a chart assembly 7 is detachably installed on the top of the test mechanism 2. The chart assembly 7 is printed with a dial for marking the temperature and pressure measurement range, scale and other information. When the temperature pointer assembly 3 and the pressure pointer assembly 4 rotate, the operator can clearly read the temperature and pressure values according to the corresponding scale on the chart assembly 7 pointed to by the pointer.
[0038] Specifically, the test mechanism 2, temperature pointer assembly 3, and pressure pointer assembly 4 are covered by a case 8. The bottom of the case 8 is detachably connected to the bottom of the test mechanism 2, providing physical protection for the internal test components. This effectively blocks the influence of external dust, moisture, and impacts, ensuring the accuracy and stability of the measurements. A transparent cover 9 is installed on the top of the case 8. The transparent cover 9 is made of glass, which has good light transmission and wear resistance, effectively resisting external scratches and maintaining good visibility. A cover ring 10 is installed at the connection between the case 8 and the transparent cover 9. The cover ring 10 is annularly clamped on the outside of the case 8 and the transparent cover 9, which strengthens the connection between the case 8 and the transparent cover 9, making the connection tighter and more stable. This prevents the transparent cover 9 from loosening or falling off during equipment use, reduces the entry of dust and moisture into the interior of the case 8 through the connection gaps, and further enhances the protection performance of the internal components.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
