Description

(1) Technical field [0001] The invention relates to a safety protection device for a closed pipeline of a volatile poisonous liquid, especially when the closed pipeline contains a volatile poisonous liquid. It belongs to the technical field of chemical machinery engineering equipment. (2) Background technology [0002] In recent years, with the rapid development of key technologies in the fields of meteorology, electronics, pharmaceuticals, and biology, higher requirements have been put forward for the detection of the surrounding environment, especially the humidity. Not only high measurement accuracy is required, but also a wide measurement range is required. A corresponding humidity generator is required to realize it. As far as the working principle of the current humidity generator is concerned, it mainly adopts the shunt method, double pressure method, double temperature, double temperature and double pressure, etc., especially through strict control of temperature and...

Problems solved by technology

The dual temperature and dual pressure with high measurement accuracy and wide measurement range puts forward new requirements for the control of temperature and pressure. In terms of temperature alone, it is required that the temperature can be changed within the range of -90 to +85°C, which requires a closed tube. The liquid in the road can maintain a liquid state in this temperature range and the viscosity should not be too large. In the existing humidity field, two liquids, ethanol and water, are mostly used to meet the requirements of low stability and high temperature respectively, which leads to the final equipment volume Large, expensive, and difficult to design
