Structural design and performance test of venturi steam trap with flow rate adaptive adjustment

Aiming at the shortcomings of existing venturi steam traps in practical application, a new type of venturi steam trap with self-adaptive flow rate was proposed. The structure of the venturi steam trap has the characteristics of automatic drainage and good drainage effect, small size, low failure rate and long service life. Of venturi steam hydrophobic internal parts structure design theory, the new type of venturi tube throat diameter was determined and the expansion period of Angle and length, using FLUENT software to the new designed venturi steam trap are simulated, and compared with the original venturi steam drain structure carries out a comparative analysis on the simulation results, the simulation results show that: The effect of hydrophobicity is more obvious when the venturi tube is extended. The new venturi steam trap was cast and tested on the spot. The test results showed that the experimental results were highly consistent with the theoretical results, and the new Venturi steam trap could meet the technological requirements.
