Description

Technical Field

[0001] This utility model relates to the field of petrochemical product testing instruments, and in particular to a novel equilibrium method low-temperature closed-cup flash point meter. Background Technology

[0002] The novel equilibrium-based low-temperature closed-cup flash point analyzer is a testing tool designed for low-temperature, trace-volume, complex samples and high-precision applications. Through automated rapid equilibrium technology, it breaks through the performance limitations of traditional methods, significantly improving safety, efficiency, and compliance. It is commonly used in petrochemical, biofuel, and coating / ink industries.

[0003] The existing product involves sealing and securing a container containing the sample inside a heating platform with screws. The instrument is then activated to heat the liquid to be tested. A gas valve is then opened, and a lighter ignites the flame. When the liquid reaches the measurement temperature, the valve on the lid is quickly pulled open, causing the flame to ignite the liquid vapor. This process is repeated until the liquid vapor is ignited.

Incomplete combustion of the gas may cause errors in the experiment, making the experimental data inaccurate.

The handle 2 is used by the operator to open and close container 28.

[0021] Working principle: When using this new type of equilibrium method low-temperature closed-cup flash point meter, firstly, the liquid to be measured is added to container 28. Then, the cable 6 is energized through the operating platform 1. The current passes through the Y-tube 34 and the copper column 17, heating the resistance wire 12 until it is red-hot. When the heating platform 4 heats the liquid in container 28 to the required measurement temperature, the lever 5 is pulled, which drives the sliding cover 11. The sliding cover 11 then drives the protective shell 19 through the connecting column 23, rotating around the shaft 18. The rotation point deflects, and when the resistance wire 12 reaches its lowest point, it ignites the flammable gas inside the container 28 under the opening below the sliding cover 11. Then, quickly push the lever 5 back, repeating this process until the required data is obtained. When the resistance wire 12 needs to be replaced, press down on the pressing plate 13 to push the connecting post 16 downwards, causing the clamping plate 15 to release the locking state of the copper post 17. Then, pull out the copper post 17, replace it with a new one, and release the pressing plate 13. The copper post 17 is located outside the connecting post 16. Spring 14 on the wall will reset clamp 15 and lock copper column 17 again. This design facilitates quick replacement of resistance wire 12, reduces downtime, and replaces the original gas flash point, making it safer and improving the accuracy of experimental data. After placing the container 28 filled with liquid into the slots of heating platform 4 and cover plate 3, align the slot on top cover 10 with locking tooth 29 and put the cover down. The inclined surface on locking tooth 29 will cause locking tooth 29 to move backward briefly and enter the slot on top cover 10. Under the limit of sliding column 26 and the elasticity of spring 27, top cover 10 is locked. When it is necessary to remove the cover, the lever 9 needs to be pushed backward. The lever 9 drives connecting plate 20, and then connecting plate 20 drives rotating ring 36. Rotating ring 36 drives locking tooth 29 to move backward under the limit of sliding column 26, compressing spring 27 and releasing the lock on top cover 10. This design facilitates quick and convenient opening of top cover 10, removal of container 28 for cleaning, and convenient conduct of the next set of experiments.
