Ukuba nempilo ende yesevisi nesikhathi esinganakekeli kuzoncika ezintweni ezilandelayo: izimo zokusebenza ezivamile, ukugcinwa kwezinga lokushisa elivumelanayo/ingcindezi, kanye nedatha yokugqwala enengqondo.
Lapho i-valve yebhola ivaliwe, kusekhona uketshezi olucindezelayo emzimbeni we-valve.
Ngaphambi kokulungiswa: khulula ukucindezela kwepayipi, gcina ivalvu isendaweni evulekile, nqamula amandla noma umthombo womoya, futhi uhlukanise isisebenzisi kubakaki.
Ngaphambi kokusebenza kokuhlakazeka nokuwohloka, ingcindezi yamapayipi akhuphuka nomfula kanye nezansi nomfula wevalvu yebhola kufanele ihlolwe.
Ngesikhathi sokuqaqa kanye nokuhlanganisa kabusha, ukunakekelwa kufanele kuthathwe ukuze kuvinjelwe ukulimala ezindaweni zokuvala izingxenye, ikakhulukazi izingxenye ezingezona ezensimbi.Amathuluzi akhethekile kufanele asetshenziswe lapho kukhishwa ama-O-rings.
Amabhawodi ku-flange kufanele aqiniswe ngokulinganayo, kancane kancane, futhi ngokulinganayo.
I-ejenti yokuhlanza kufanele ihambisane nerabha yevalvu yebhola, ipulasitiki, insimbi, nendawo yokusebenza (njengegesi).Lapho indawo yokusebenza iyigesi, izingxenye zensimbi zingahlanzwa ngophethiloli (GB484-89).Hlanza izingxenye ezingezona ezensimbi ngamanzi ahlanzekile noma utshwala.
Izingxenye ezingezona ezensimbi kufanele zisuswe ku-ejenti yokuhlanza ngokushesha, futhi akufanele zicwiliswe isikhathi eside.
Ngemuva kokuhlanza, kuyadingeka ukwenza i-volatilize i-ejenti yokuhlanza odongeni (sula ngendwangu kasilika engazange ifakwe ku-ejenti yokuhlanza) ukuze ihlangane, kodwa akufanele ibanjwe isikhathi eside, ngaphandle kwalokho, izogqwala futhi bangcoliswe uthuli.
Izingxenye ezintsha kufanele futhi zihlanzwe ngaphambi kokuhlanganiswa.
Phakathi nenqubo yokuhlanganisa, akumele kube nemfucumfucu yensimbi, imicu, amafutha (ngaphandle kokusetshenziswa okucacisiwe), uthuli nokunye ukungcola, izinto zangaphandle, nokunye ukungcola, ukunamathela noma ukuhlala phezu kwezingxenye noma ukungena emgodini wangaphakathi.Khiya isiqu namantongomane uma kukhona ukuvuza okuncane ekupakisheni.
A), ukususa
Qaphela: Ungakhiyi uqine kakhulu, imvamisa ukujika okungu-1/4 kuya koku-1 ngaphezulu, ukuvuza kuzoma.
Beka ivalvu endaweni evuleke uhhafu, shayela, futhi ukhiphe izinto eziyingozi ezingaba khona ngaphakathi nangaphandle komzimba wevalvu.
Vala i-valve yebhola, susa ama-bolts okuxhuma namantongomane kuma-flanges nhlangothi zombili, bese ususa ngokuphelele i-valve epayipini.
Hlukanisa idivayisi yokushayela ngokushintshana - i-actuator, ubakaki wokuxhuma, iwasha yokukhiya, i-stem nut, i-butterfly shrapnel, i-glam, ishidi elingagugi, ukupakishwa kwesiqu.
Susa isembozo somzimba amabhawudi axhumayo namantongomane, hlukanisa isembozo sevalvu emzimbeni wevalvu, bese ukhipha i-gasket yekhava yevalvu.
Qinisekisa ukuthi ibhola lisendaweni evaliwe, okwenza kube lula ukususa emzimbeni, bese ususa isihlalo.
Phusha isiqu se-valve siye phansi embotsheni ye-valve size sikhishwe ngokuphelele, bese ukhipha i-O-ring kanye nokupakisha ngaphansi kwesiqu se-valve.
B), hlanganisa kabusha.
Qaphela: Sicela usebenze ngokucophelela ukuze ungaklwebheli isiqu se-valve kanye nengxenye yokuvala yebhokisi lokugxusha lomzimba we-valve.
Ukuhlanza nokuhlolwa kwezingxenye ezihlakaziwe, kunconywa kakhulu ukuthi kushintshwe izimpawu ezifana nezihlalo zama-valve, ama-bonnet gaskets, njll.
Hlanganisa ngokulandelana kwe-disassembly.
Qinisa amabhawodi oxhumano lwe-flange ngetorque eshiwo.
Qinisa i-stem nut ngetorque eshiwo.
Ngemva kokufaka i-actuator, faka isignali ehambisanayo, bese ushayela umgogodla we-valve ukuze ujikeleze ngokuzungezisa isiqu se-valve, ukuze i-valve ifinyelele endaweni yokushintsha.
Uma kungenzeka, sicela wenze ukuhlolwa kokuvala ingcindezi kanye nokuhlolwa kokusebenza kwevalvu ngokuya ngezindinganiso ezifanele ngaphambi kokuphinda ufake ipayipi.
