Yiziphi izidingo zokufaka ama-valve ebhola?

Kunezidingo ezikhethekile ezehlukene zokufakwa kweama-valve ebholaukuqinisekisa ukusebenza kwazo okujwayelekile kanye nokusebenzisa isikhathi eside.

Umsebenzi wokulungiselela ngaphambi kokufakwa ubalulekile. Hlola ngokucophelela isimo sepayipi ukuze uqinisekise ukuthi i-coaxial futhi izindawo ezimbili zokuvala ama-flange ziyahambisana. Ngesikhathi esifanayo, qinisekisa ukuthi ipayipi linamandla anele ukumelana nesisindo se-valve yebhola. Uma amandla enganele, usekelo kufanele lwengezwe. Kudingekile ukususa ngokuphelele ukungcola okufana namafutha kanye ne-welding slag kusuka epayipini ukuze kuvinjwe ukuthi zingangeni ngaphakathi kwe-valve yebhola futhi zibangele umonakalo endaweni yokuvala nezinye izingxenye. Ngaphezu kwalokho, kuyadingeka ukuthi uhlole ngokucophelela izimpawu ze-valve yebhola, uqinisekise ukuthi iqinile futhi ayilimele, futhi usebenzei-valve yebholaivuleke ngokugcwele futhi ivalwe izikhathi ezimbalwa ukuze kuqinisekiswe ukuthi izenzo zayo zokuvula nokuvala ziyavumelana nezimo futhi zivamile.

Ngesikhathi sokufakwa, i-i-valve yebholaingafakwa kunoma iyiphi indawo njengokuphela komfula. Ukuze uthole ama-valve ebhola, izikhundla zabo zokufaka ziyaguquguquka; Kodwa ama-valve amabhola anama-actuator afana nama-gearbox, ama-actuator womoya, njll. kufanele afakwe aqonde ngangokunokwenzeka ukuze kugcinwe indawo yokungena nama-valve ivundlile. Lapho uxhuma ama-flanges, i-gasket yokuvala uphawu kufanele ibekwe ngokuvumelana nezidingo zokuklama, futhi ama-bolts kufanele aqiniswe ngokulinganayo, kancane kancane, futhi ngokulinganayo ukugwema ukuvuza. Kumele kuqashelwe ukuthi i-actuator akufanele isetshenziswe njengendawo yokuphakamisa ngesikhathi sokufakwa ukugwema ukulimala. Uma i-valve yebhola ixhunywe epayipini futhi kukhona ukulenga okuphansi noma isimo esithwala amandla angaphandle epayipini eliseduze, ubakaki kufanele usetshenziselwe ukuqeda ukuchezuka nokuqinisekisa ukuzinza kwepayipi.

Ngemva kokufaka, ukuhlolwa okuningiliziwe kusadingeka. Qala i-valve yebhola kuqala, yenza imisebenzi eminingi yokuvula nokuvala, bheka ukuthi isenzo sayo siyavumelana nezimo, noma amandla afanayo, nokuthi isimo sokusebenza sijwayelekile yini. Ngemva kwalokho, ngokwezidingo zokuklama ingcindezi yepayipi, indawo ehlangene phakathi kwe-valve yebhola kanye ne-flange yepayipi ingaphansi kokuhlolwa kwengcindezi ukuze kubhekwe ukuthi ukusebenza kokuvala kuhle yini nokuqinisekisa ukuthi akukho ukuvuza okwenzekayo. Kungale ndlela kuphela ingasetshenziswa ngokuzethemba.
