Problems solved by technology
As the vapor measuring device 1 rotates, the probability of leakage at the interface is greater. During the vapor pressure measurement test, the inspector cannot monitor the whole process, and the connecting hose 3 still has a kink problem, which causes the air pressure measurement value to fluctuate from high to low, causing errors. The test requires an absolutely airtight environment, and a small leak will cause the test to fail and must be restarted
When using this measuring instrument, the inspectors smear soapy water on the interface before and during the test, and repeatedly observe whether there is any leakage. However, this method is time-consuming and laborious, but the effect is not satisfactory, resulting in low measurement efficiency and a waste of manpower and labor. time
[0005] In addition, the connecting hose 3 and the quick connector 2 will age after being used for a long time, and are more likely to leak

Description
technical field [0001] The invention relates to the field of petroleum product detection, in particular to an integrated vapor pressure detector. Background technique [0002] Vapor pressure is an important physical property of volatile liquids. It is a very critical factor for motor gasoline and aviation gasoline, affecting the tendency of air lock when starting, warming up and operating at high temperature or high latitude. In some areas, the law stipulates the maximum vapor pressure limit of gasoline as an important measure to prevent air pollution. The vapor pressure of crude oil is of great significance to the operation of crude oil production and refining, and initial refining and processing. Vapor pressure can also be used as an indirect measure of the evaporation rate of volatile petroleum solvents. [0003] GB / T8017 "Determination of Vapor Pressure of Petroleum Products (Reid Method)" stipulates the method for determining the vapor pressure of gasoline, other v...
