Ukuhlaziywa nokwelashwa kokuvuza kwangaphakathi kanye nokuvuza kwangaphandle kwama-valves e-Cryogenic

1. Ukuvuza kwangaphakathi kwevalve ye-cryogenic:

Ukuhlaziya:Ukuvuza kwangaphakathi kwe-valve yokushisa okuphansi kubangelwa ikakhulukazi ukuguga noma ukuguqulwa kwendandatho yokuvala.Phakathi nesigaba sokusebenza kwesilingo sephrojekthi, kusekhona ukungcola okuncane okufana nesihlabathi kanye ne-slag yokushisela epayipini, okuzobangela ukuguga kwendawo yokuvala i-valve lapho i-valve ivuliwe noma ivaliwe.

Ukwelashwa:Ngemuva kokuthi i-valve isendaweni yokuhlolwa nokufakwa kwengcindezi, uketshezi olusele kanye nokungcola emzimbeni we-valve kufanele kuhlanzwe.Ngakho-ke, izinyathelo zokulungisa endaweni ezihlinzekwa umenzi kanye nezindaba ezidinga ukunakwa ekuhlolweni kwendawo kufanele kuhlanganiswe ngesikhathi sokwakha.Yazisa isayithi futhi ulawule ngokuqinile ikhwalithi ukuze kube lula ukukhiqizwa, ukusebenza nokugcinwa kwephrojekthi esikhathini esizayo.

2. Ukuvuza kwevalve ye-cryogenic:

Ukuhlaziya:Izizathu zokuvuza kwama-valve e-cryogenic zingahlukaniswa ngezizathu ezine ezilandelayo:

1. Ikhwalithi ye-valve ngokwayo ayilungile ngokwanele, ngamabhamuza noma imifantu yegobolondo;

2. Ngesikhathi senqubo yokufaka, lapho i-valve ixhunywe ku-flange esetshenziselwa ipayipi, ngenxa yezinto ezihlukahlukene zezinsimbi zokuxhuma kanye nama-gaskets, ngemva kokufaka okuphakathi epayipini, endaweni yokushisa ephansi, izinto ezihlukahlukene ziyancipha ngokuhlukile. , okuphumela ekuphumuleni;

3. Indlela yokufaka ayilungile;

4. Ukuvuza esiqwini se-valve nokupakishwa.

 Indlela yokucubungula imi kanje:

1. Ngaphambi kokuthi kukhishwe isaziso se-oda, imidwebo nemiklamo enikezwe umenzi kufanele iqinisekiswe futhi iqedwe ngesikhathi, futhi umqondisi wefekthri kufanele axhumane ngesikhathi.Izinto zokusetshenziswa ezingenayo kufanele zibuyekezwe ngokuqinile, futhi i-RT, UT, PT kufanele yenziwe ngokuya ngezidingo zobuchwepheshe.ukuhlola, bese benza umbiko obhaliwe.Nikeza ishejuli yokukhiqiza enemininingwane.Enqubweni yokukhiqiza yesikhathi esizayo, uma zingekho izimo ezikhethekile, ukukhiqizwa kufanele kwenziwe ngokuqinile ngokuvumelana nesimiso ngekhwalithi eqinisekisiwe kanye nobuningi, futhi umsebenzi wokuhlola oqinile kufanele wenziwe ngaphambi kokushiya imboni.

2. Ivalvu ephawulwe ngesiqondiso sokugeleza kufanele inake uphawu lwesiqondiso sokugeleza emzimbeni wevalvu.Ukwengeza: Ngenqubo, kubaluleke kakhulu ukulawula isikhathi sokuqala sokupholisa se-valve ukuze i-valve ikwazi ukupholisa ngokugcwele iyonke.Kuyadingeka ukuhlola njalo ukuthi udonga lwangaphakathi lwe-valve lunemifantu, i-deformation kanye nokugqwala kwendawo yangaphandle, ikakhulukazi ekushiseni okuphansi.I-valve ye-medium ijwayele ukwanda nokunciphisa ukushisa.Ukuze i-valve ngaphansi kwezimo ezinzima ezifana ne-cavitation, kuyadingeka ukuqinisekisa amandla ayo okucindezela, izinga lokushisa eliphansi nokumelana nokugqoka.
