Abstract
Description
Technical Field
[0001] The utility model relates to the field of sensor measurement, in particular to a sensor measurement device for simulating high-pressure environment. Background Art
[0002] Online pH electrodes have been widely used in industries such as tap water, river water, chemical industry, and medicine. During the application process, many scenarios involve high-pressure environments. In traditional technologies, laboratory pressure simulation devices usually use steam sterilizers, but their pressure is relatively small, within 0.3MPa, and can only meet some short-term low-pressure experiments. The reason why this type of sterilizer has low pressure is that its pressure comes from the steam pressure after heating. This pressure has a safety threshold. When the pressure exceeds the threshold, it will automatically release the pressure to achieve pressure balance and ensure the safety of the experiment. In addition, this method cannot perform long-term pressure experiments. When the sterilizer stops heating, its pressure will drop as the temperature drops, and long-term heating will pose a safety hazard.
[0003] There is also a way to reach a test pressure of 1MPa in the laboratory, which is to use a high-pressure water pump, but this method requires some larger water storage containers or supporting pipelines. When conducting experiments, if you want to use a high-pressure water pump, the operation is quite cumbersome and complicated, and the noise is very loud.
[0004] In reality, many scenarios need to meet the requirements of 6MPa or even 10MPa. Therefore, in order to study the sensor measurement effect under such conditions, it is necessary to develop a set of high-pressure environment sensor measurement devices to simulate the user's usage conditions, verify the performance of the sensor, etc., and provide technical support to developers. It has certain application prospects and market value.
[0005] To solve the above problems, we made a series of improvements. Utility Model Content

[0015] The following is a further description of the present invention in conjunction with specific embodiments. It should be understood that the following embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.
[0016] Example 1
[0017] Figure 1 It is a structural schematic diagram of the utility model.
[0018] like Figure 1 As shown, a sensor measurement device for simulating a high-pressure environment includes: a gas cylinder 100, a pipeline 200, a pressure regulating and detecting mechanism 300, a pressure container 400, a sensor 500 and a PC 600. The gas cylinder 100 is connected to the pressure container 400 through the pipeline 200, the pressure regulating and detecting mechanism 300 is connected to the pressure container 400 and the pipeline 200, the sensor 500 is arranged in the pressure container 400, and the sensor 500 is connected to the PC 600 through a wire;
[0019] Among them, the pressure regulation detection mechanism 300 includes: a first pressure gauge 310, a second pressure gauge 320, a pressure regulating valve 330, a safety valve 340 and an air release valve 350. The first pressure gauge 310 and the pressure regulating valve 330 are connected to the pipeline 200, and the second pressure gauge 320, the safety valve 340 and the air release valve 350 are connected to the outside of the pressure container 400.
[0020] The principle of the utility model is that the gas cylinder 100 is connected to the pressure vessel 400, and the first pressure gauge 310 and the regulating valve 330 are installed on the pipeline 200 to monitor and adjust the pressure in real time; the second pressure gauge 320, the safety valve 340, and the air release valve 350 are installed on the pressure vessel 400 to ensure the safety of the pressure test. The sensor 500 is installed in the pressure vessel 400 and connected to the PC600 end through a wire. By pressurizing the pressure vessel 400 through the gas cylinder 100, the working conditions of the sensor 500 under different pressures can be simulated.
[0021] The innovation of this utility model is that we have made some improved designs based on the problems mentioned in the background technology.
[0022] First, our pressure source is replaced with a high-pressure gas cylinder, which mostly contains nitrogen or air. Usually, the pressure of a high-pressure gas cylinder can reach more than 4MPa. The pressure can be adjusted by a pressure regulating valve, and the test pressure can be adjusted at any time, whether it is constant pressure or variable pressure. When the gas in the gas cylinder is exhausted, the regulating valve can be closed and the gas cylinder can be replaced, which will not affect the experimental pressure and ensure the stability of the experiment. Secondly, we install the first pressure gauge 310 and the second pressure gauge 320 on the pressure vessel; the safety valve 340, which can automatically release the pressure when the pressure is too high through the safety valve 340 to ensure the safety of the experiment; the air release valve 350, which can realize manual pressure release through the air release valve 350, and can be used for pressure regulation during the experiment; the sensor 500, the number of sensors 500 can be modified according to the actual situation. In this embodiment, there is only one. When multiple sensors 500 need to be installed, it is only necessary to modify the number of corresponding mounting holes.
[0023] The above design can simulate pressure conditions up to 12MPa, which can be applied to simulation tests of deep-sea sensors at a depth of about 100 meters, providing a convenient and reliable simulation device for the entire sensor development and testing.
[0024] Compared with the traditional technology, the utility model can simulate some actual working conditions on site, so as to achieve the function of discovering and solving problems.
[0025] The specific implementation modes of the present invention are described above, but the present invention is not limited thereto. The present invention can also have various changes without departing from the purpose of the present invention.
