Optimism Product Life of Pilot-Operated Valves Basan on Tribology |
| |
| Abstract: | This paper presents the design features of a foreign-made pilot-operated valve. In light of the theory of frictional wear, the author conducts an investigating into the constant - force springloaded stem coupling and thegate-to-seat seals and reveals that the extended service life of such valves depends mainlyon the stem coupling with Bellevilla springs, the elastie gate made of high-strength brass, and the high-rigidity valve body. |
