Iyunithi yokucwenga uwoyela embonini ye-petrochemical ihloselwe ukucubungula uwoyela ongahluziwe, ukukhiqiza izinhlobo ezahlukene zikaphethiloli, udizili, uphalafini namanye amafutha kaphethiloli, uwoyela wokugcoba nezinto zokusetshenziswa zamakhemikhali.
Izidingo eziyisisekelo zesitshalo sokucwenga uwoyela we-valve: ukuhlangabezana nezidingo zenqubo, qinisekisa impilo yesevisi ye-valve, kulula ukuyisebenzisa nokuyigcina, isakhiwo esihlangene, iphephile futhi ifaka ubufakazi bokuqhuma.
1. Izidingo zokubekwa uphawu
I-Stem seal: Ukupakisha okusetshenziswe ku-valve kumele kuhlangabezane nezidingo zenqubo yenqubo futhi kuhambisane nezinga lokushisa nokucindezela kwe-medium.Amabhokisi okugxusha ama-valve avame ukuvuza ngesikhathi sokusebenza kwamayunithi amaningi, izihlungi eziningi zishintsha konke ukupakisha ngaphambi kokusebenza.
2. Izidingo zezinto zokwakha
Izinto zevalvu ezisetshenziswa ezitshalweni zokucwenga uwoyela ikakhulukazi zifaka i-carbon steel, i-alloy steel nensimbi engagqwali.Ukuze kuthuthukiswe inqubo yokucwenga, izinguquko ezakhiweni zikawoyela ongahluziwe, ukucutshungulwa okujulile kukawoyela ongahluziwe, kanye nokwenyuka kwezinga lokushisa nokucindezela kwezimo zokusebenza, kunezidingo ezintsha zezinto zama-valve, njengezinto ezimelana nokugqwala SS316. kanye ne-polymeric linings.

3. Izidingo zokuphepha
Imboni yokucwenga uwoyela ijwayele ukuba nezingozi ezivuthayo neziqhumane ngesikhathi sokuthutha, ngakho-ke izidingo zokuphepha zamavalvu ziqinile, futhi akufanele kuqhume futhi kungashi.Ngokwesibonelo,ama-valve ebhola kagesi angaqhumifuthiama-valve emvemvane kagesi angaqhumiingasetshenziswa kahle kule medium.
4. Izidingo zokucaciswa
Imboni yokuhluza uwoyela idlala indima ebalulekile emnothweni wezwe, futhi izinzuzo zezomnotho zezindawo ezihluza uwoyela zihlobene eduze nesilinganiso sazo.Ngakho-ke, indawo yokucwenga emikhulu iyinkambiso yentuthuko yesikhathi esizayo.Izinzuzo ukonga ukutshalwa kwezimali, ukunciphisa ukusebenza komhlaba, ukunciphisa izindleko, nokunciphisa ukusetshenziswa kwamandla, ngakho-ke umkhuba wamavalvu azishintshayo uya ngokuya uqashelwa.

I-COVNA yethu igxile ekukhiqizeni ama-valve azenzakalelayo, futhi ineminyaka eminingi yesipiliyoni sobunjiniyela esicebile esineminyaka eminingi yesipiliyoni kumaphrojekthi wobunjiniyela be-petroleum kanye nokuhluza.

Uma uyindawo yokucwenga edinga ama-valve noma ufuna ukuthola izixazululo ezengeziwe zamavalvu okuhluza, sicela.Xhumana nathi.
