Cov tub ntxhais kev ua haujlwm thiab cov kev tswj hwm kev ntawm ntab lub valve.
Cov Ntsiab Lus thiab Kev Lag Luam Raws Li
Ntab pob pob valve yog cov khoom tseem ceeb hauv kev siv hluav taws xob. Cov tub ntxhais muaj nuj nqi ntawm cov ntab pob pob valve yog kaw thiab tswj hwm los ntawm kev tsav pob pob tawg nrog daim ntaub ntawv dielectric. Hauv kev lag luam tshuaj, kev kho mob fais fab thiab yog li ntawm kev tswj dej ncaj qha cuam tshuam ncaj qha cuam tshuam cov txheej txheem kev ruaj ntseg, lub zog txuag thiab khoom siv nyiaj. Piv txwv li, hauv liquefied ntuj cia tank qib yuav tsum tau nruj me ntsis kev tswj hwm mus rau ± 1% lossis tsawg dua, txwv tsis pub muaj kev nyab xeeb yuav tshwm sim.
Lub ntsiab lus kev tsis sib haum ntawm ntws tswj qhov
Kev lig kev cai, pob li qub muaj qhov zoo qhib thiab kaw thiab txhim khu kev qha cov peev txheej yog feem ntau tsis quav ntsej. Hauv kev siv cov kev siv, tshuav nyiaj yuav tsum tau sib npaug ntawm kev sib khi ua tau zoo thiab kho kom zoo tswj:
- Cov kev mob siab: kev pheej hmoo ntawm kev coj ua hluav taws xob sib xws ua rau kev hloov pauv hloov;
- Qhov chaw kub tsawg: cov khoom shrinkage cuam tshuam rau kev sib khi thiab cov txheej txheem kab ntawv;
- Kev hloov kho ntau zaus: Cov lus teb ceev thiab precision ntawm tus actuator tsis txaus.
- Piv txwv li, cov refeant piv ua yuam kev yuav tsum tsawg dua los yog sib npaug rau 1%, uas yog qhov yuav tsum tau ua rau pob valve ntws tswj qhov raug.
