Description

[0001] The present invention relates to the technical field of gas mixing and regulation, and in particular to equipment and methods for regulating and controlling the mutual mixing of one or more gases. Background Art

[0002] In the process of automobile energy application, various valves are used. For example, the use of automobile hydrogen energy will use special hydrogen energy valves, as well as various equipment that needs to be in contact with hydrogen, nitrogen, and other mixed gases. These valves or equipment are referred to as HSM equipment. Before actual use, HSM equipment will undergo various tests to verify the efficiency and service life of the HSM equipment in this environment. Therefore, it is necessary to control the ratio of multiple gas mixtures, temperature, humidity, pressure and other indicators, so that it is easy to find out where this type of equipment has deficiencies or needs improvement.

[0003] During the test, one or more gases need to be added into a closed system and mixed with each other. Because it is a closed system, it is not convenient to detect, so it is not convenient to control the direct mixing ratio of multiple gases. Therefore, the environment provided in this way is not enough to simulate the environment of the components in actual work.

[0004] In addition, after one or more gases are used in experiments or tests, if these gases are discharged into the air, this will inevitably lead to atmospheric pollution. In order to reduce atmospheric pollution and damage to the ecological environment, it is necessary to reduce the emission of such gases or recycle them. Summary of the invention

[0043] The water circulation system includes a chiller 23, the water outlet of the chiller 23 is respectively connected to the water inlet of the humidifying tank 13 and the water inlet of the water bath vaporizer 5, the water outlet of the water bath vaporizer 5 is connected to the water inlet of the cold dryer 22, the water outlet of the cold dryer 22 is connected to the water tank of the air pump 2, and the water outlet of the water tank of the air pump 2 and the water outlet of the humidifying tank 13 are respectively backflow-connected to the water return port of the chiller 23 to form a water circulation;

[0047] The gas mixing and regulating device can accurately control the gas mixing ratio and real-time control the temperature, humidity and pressure of the gas inside the system through the above-mentioned components and connection methods, thereby providing a variety of accurate simulation environments for the HSM device 1 in a confined space, thereby testing the use efficiency and service life of the HSM device 1 under different environments, thereby finding out the possible deficiencies and defects of the components of the HSM device 1 in actual use and making improvements; at the same time, the gas generated by the device after testing or experiment can also be recycled, reducing pollution to the atmosphere and damage to the ecological environment.

[0048] The first pressure sensor 9 and the second pressure sensor 36 can obtain the pressure of the gas in the inlet and outlet pipes of the humidification tank; when a gas is introduced into the system, the gas pressure value can be measured according to the pressure sensor.
