Description

Technical Field

[0001] The invention relates to the technical field of pressure detection instruments, in particular to an integrated temperature and pressure acquisition mechanism. Background Art

[0002] Pressure testing instruments are devices used to measure and monitor the internal pressure of gases or liquids. They are widely used in many fields such as industry, scientific research and engineering. These instruments can provide real-time pressure data for system monitoring, troubleshooting and operation control.

[0003] However, the prior art usually installs the pressure sensor and the temperature sensor in a fixed position on the reaction chamber, which makes it difficult for the sensor to get close to the reaction material, reducing the accuracy of data collection. In addition, since the reaction chamber also needs to be arranged with some observation windows, there will be interference with the sensor position. To ensure the position of the observation windows, the sensor cannot be installed in the ideal position in many cases. Moreover, the fixed position where the pressure sensor and the temperature sensor are installed on the reaction chamber increases the number of openings on the chamber, increasing the difficulty of installation and the risk of air leakage.

[0018] Beneficial Effects

[0019] Compared with the prior art, the present invention provides an integrated temperature and pressure acquisition mechanism, which has the following beneficial effects:

[0020] 1. The integrated temperature and pressure acquisition mechanism can ensure that the sensor is arranged in an ideal position by integrating the pressure sensor and the fixing rod on the main body of the material pressure instrument, thereby improving the accuracy of data acquisition, reducing the position occupied on the reaction chamber, optimizing the overall design layout, making the equipment more compact and more functional, and providing more convenience for the installation of components such as observation windows, air inlets and outlets, and burst valves. In addition, the sensor can be taken out along with the material flange, which is beneficial to the maintenance of the sensor, thereby optimizing the performance and user experience of the equipment.

[0021] 2. The integrated temperature and pressure acquisition mechanism, by setting a sealing component, places the material flange inside the clamp, and can drive the sliding block to slide through the clamping of the clamp. The sliding of the sliding block can drive the push rod to slide to the outside of the material flange. The push rod abuts against the inner wall of the clamp, so that the surface of the elastic plate is tightly abutted against the inner wall of the clamp, which can enhance the sealing of the material flange after it is fixed, improve the sealing inside the main body of the pressure instrument, reduce the leakage of internal gas or liquid, and ensure the accuracy and stability of the measurement data.

[0022] 3. In this integrated temperature and pressure acquisition mechanism, when the sliding block slides, the sealing cavity and the inside of the cavity are both in a strong pressure state, which can make the surface of the elastic plate closer to the inner wall of the clamp, further improve the sealing performance, and make the temperature and pressure measurement more stable.
