Lub sealing yam ntxwv ntawm kub kub pob li qub

Lub sealing yam ntxwv ntawm kub kub pob li qub:

1. Lub sealing yam ntxwv ntawm kub kub pob li qub feem ntau yog hlau sealing khub. High-temperature pob valve yog tsim rau qhov kub thiab txias ntau yam. Tsis muaj qhov sib txawv tseem ceeb hauv thermal expansion coefficients ntawm ntau yam hlau. Tsuav koj xaiv nws kom raug, nws yeej yog tib yam. Kho qhov kub sib txawv deformation.

2. Qhov tsis zoo ntawm qhov kub-kub pob valve seals yog cov khoom siv tawv thiab cov khoom sib khi yuav tsum siab tshaj qhov siab. Vim yog lub siab loj ntawm cov khoom sib khi, txawm tias siv cov khoom sib khi ua ntej, lub rooj zaum valve thiab pob yuav hnyav heev. Tsis tas li ntawd, vim tias qhov sib txhuam coefficient ntawm cov hlau npog loj, qhov qhib thiab kaw torque ntawm lub pob valve yuav loj dua. Yog li ntawd, feem ntau thermal pob li qub siv txhim khu kev qha kev ua tau zoo, muaj zog elastic them nyiaj thiab broad-wide elastic sealing khub ntawm qhov kub thiab txias, yog li nws tsim nyog rau ntab thiab ruaj pob li qub.

3. Vim yog lub zog ua ntej nruj thiab cov nyhuv ntawm hydraulic siab, lub rooj zaum valve thiab cov khoom yog compressed, thiab lub hau ntawm lub rooj zaum valve yog deformed thiab kaw. Cov nyhuv sealing yog nyob ntawm lub rooj zaum valve kom them nyiaj rau lub roundness thiab me ntsis uniformity ntawm lub pob nyob rau hauv qhov kev txiav txim ntawm cov kua siab thiab pre-tightening.
