Txij li thaum qhib lossis kaw stroke ntawm lub valve qia ntawm qhov qis-kub nres valve yog luv luv thiab muaj kev txhim khu kev qha zoo heev, thiab vim tias qhov kev hloov ntawm lub rooj zaum valve qhib yog proportional rau stroke ntawm lub valve disc, nws yog heev. haum rau regulating ntws. Yog li ntawd, hom valve no yog qhov tsim nyog rau kev siv los ua kev txiav tawm lossis kev tswj hwm zoo li throttling.

- Cov kev ua yuam kev thiab kev daws teeb meem thaum siv lub ntiaj teb cryogenic li qub
① Valve sealing nto puas lawm
Qhov ua rau kev puas tsuaj rau lub valve sealing nto yog:
Ua ntej debugging cov cuab yeej, cov kav dej tsis tau tawg, tawm hauv oxide nplai thiab impurities tom qab vuam hauv cov kav dej.
Txoj kev tiv thaiv yog kom tawg tag nrho cov raj xa dej ua ntej commissioning thiab ntxiv cov ntxaij lim dej rau pem hauv ntej ntawm cov khoom tseem ceeb.
② Media sab hauv to
Cov laj thawj rau sab hauv ntawm cov xov xwm muaj xws li: kev puas tsuaj rau lub sealing nto thiab suav nrog impurities.
Kev daws: Kho lub sealing nto thiab huv si impurities los tiv thaiv sab hauv to.
③ Media leakage
- Yog vim li cas rau media leakage yog:
1. Nquag qhib thiab kaw ntawm lub ntiaj teb qhov kub uas tsis tshua muaj siab ua rau hnav thiab tsim kua muag ntawm cov ntim ntim.
2. Lub valve shrinks thaum raug txias ntawm qhov kub thiab txias.
Kev daws: Tighten lub ntim compression txiv ntoo los yog hloov lub ntim.
