2.6 Ukupakishwa kweshaft yevalvu①Ngenxa yokuba iivalve kumnatha wombhobho zihlala zivulwa kwaye zivaliwe ngokungaqhelekanga, ukupakishwa kuyadingeka ukuba kusebenze iminyaka emininzi, kwaye ukupakisha akuyi kuguga, ukwenzela ukuba kugcinwe umphumo wokutywinwa ixesha elide;②Ukupakishwa kwe-valve shaft kufuneka kwakhona imelane nokuvulwa rhoqo kunye nokuvala, umphumo wokutywina ulungile;③Ngokubhekiselele kwezi mfuno zingentla, ukupakishwa kwe-valve shaft akufuneki kutshintshwe ubomi okanye ngaphezulu kweminyaka elishumi;④Ukuba ukupakishwa kufuna ukutshintshwa, idizayini ye-valve kufuneka iqwalasele imilinganiselo enokuthi ithathelwe indawo phantsi kwemeko yoxinzelelo lwamanzi.
3. Ibhokisi yokuhanjiswa kwesantya eguquguqukayo
3.1 Isixhobo somzimba webhokisi kunye neemfuno zangaphakathi nangaphandle zokuchasana nokubola zihambelana nomgaqo womzimba wevalve. i
3.2 Ibhokisi kufuneka ibe nemilinganiselo yokutywina, kwaye ibhokisi inokumelana nokuntywiliselwa kuluhlu lwamanzi lweemitha ezi-3 emva kokuhlanganisana. i
3.3 Kwisixhobo somda wokuvula nokuvala kwibhokisi, i-nati yokulungisa kufuneka ibe sebhokisini. i
3.4 Uyilo lwesakhiwo sothumelo lufanelekile. Xa uvula kwaye uvala, inokuqhuba kuphela i-valve shaft ukujikeleza ngaphandle kokuyibangela ukuba inyuke kwaye ihle. i
3.5 Ibhokisi yothumelo lwesantya esiguquguqukayo kunye netywina le-valve shaft ayinakudityaniswa kwindawo engavuziyo. i
3.6 Akukho nkunkuma ebhokisini, kwaye iindawo zokuhlanganisa izixhobo kufuneka zikhuselwe ngegrisi.
4.Ivalveindlela yokusebenza
4.1 Indawo yokuvula nokuvalwa kwendlela yokusebenza kwevalvu kufuneka ivalwe ngokwewotshi. i
4.2 Ekubeni iivalve kumnatha wombhobho zihlala zivulwa kwaye zivaliwe ngesandla, inani lokuvula kunye nokuvala ii-revolutions akufanele libe kakhulu, kunye ne-diameter-diameter valves kufuneka ibe ngaphakathi kwe-200-600 revolutions. i
4.3 Ukuze kuququzelelwe umsebenzi wokuvula nokuvalwa komntu omnye, i-torque ephezulu yokuvula kunye nokuvala kufuneka ibe yi-240m-m phantsi koxinzelelo lombhobho.
4.4 Isiphelo somsebenzi wokuvula nokuvalwa kwesivalo kufuneka sibe sisikwere se tenon enomlinganiselo olinganayo kwaye sijonge phantsi ukuze abantu bakwazi ukusisebenza ngokuthe ngqo ukusuka emhlabeni. Iivalvu ezineediski azifanelekanga kuthungelwano lwemibhobho engaphantsi komhlaba. i
4.5 Iphaneli yokubonisa yevalvu yokuvula kunye neqondo lokuvala
①Umgca wesikali wokuvula kunye nenqanaba lokuvala levalvu kufuneka uphoswe kwisigqubuthelo sebhokisi yegiya okanye kwiqokobhe lephaneli yokubonisa emva kokuba ulwalathiso lutshintshiwe, lonke lijonge emhlabeni, kwaye umgca wesikali kufuneka upeyintwe ngomgubo wefluorescent ukubonisa. ukutsala amehlo; Kwimeko engcono, ipleyiti yensimbi engenasici ingasetyenziselwa, ngaphandle koko ifakwe ipeyinti yentsimbi, ungasebenzisi ulusu lwe-aluminium ukuze wenze;③Inaliti yesalathisi ikhangele amehlo kwaye igxininiswe ngokuqinileyo, xa ukulungiswa kokuvula kunye nokuvala ngokuchanekileyo, kufuneka ivalwe ngeerivets. i
4.6 Ukuba iivalveingcwatywe nzulu, kwaye umgama phakathi kwendlela yokusebenza kunye nephaneli yokubonisa≥I-15m ukusuka emhlabeni, kufuneka kubekho indawo yokwandisa intonga, kwaye kufuneka ilungiswe ngokuqinileyo ukuze abantu baqaphele kwaye basebenze ukusuka emhlabeni. Oko kukuthi, ukuvulwa kunye nokuvala ukusebenza kwee-valve kumnatha wombhobho awufanelekanga kwimisebenzi ye-downhole.
5. Ivalveuvavanyo lokusebenza
5.1 Xa isivalo sisenziwa ngokweebhetshi zengcaciso ethile, umbutho ogunyazisiweyo kufuneka unikwe uxanduva lokwenza olu vavanyo lulandelayo lomsebenzi:①I-torque yokuvula kunye nokuvala i-valve phantsi kwemeko yoxinzelelo lokusebenza;②Ngaphantsi kwemeko yoxinzelelo lokusebenza, ukuvulwa okuqhubekayo kunye namaxesha okuvala anokuqinisekisa ukuba i-valve ivalwe ngokuqinileyo;③Ukufunyanwa kwe-coefficient yokumelana nokuhamba kwevalve phantsi kwemeko yokuhanjiswa kwamanzi emibhobho. i
5.2 Olu vavanyo lulandelayo kufuneka lwenziwe phambi kokuba isivalo siphume kumzi-mveliso:①Xa i-valve ivuliwe, i-valve yomzimba kufuneka imelane novavanyo lwangaphakathi loxinzelelo oluphindwe kabini loxinzelelo lokusebenza lwevalve;②Xa i-valve ivaliwe, omabini amacala kufuneka athwale amaxesha angama-11 uxinzelelo olusebenzayo lwevalve, akukho kuvuza; kodwa ivalve yebhabhathane etywiniweyo ngentsimbi, ixabiso lokuvuza alikho likhulu kuneemfuno ezifanelekileyo
6. I-anti-corrosion yangaphakathi nangaphandle yeevalvu
6.1 Ngaphakathi nangaphandle kweivalveumzimba (kuquka ibhokisi yothumelo lwesantya esiguquguqukayo) kufuneka uqale udutyulwe ukuze kususwe isanti kunye nomhlwa, kwaye uzame ukutshiza nge-electrostatically ukutshiza intlaka ye-epoxy engumgubo enobunzima obuyi-0 ~ 3mm okanye ngaphezulu. Xa kunzima ukutshiza nge-electrostatic resin ye-epoxy engenatyhefu kwiivalvu ezingaphezulu-enkulu, ipeyinti efanayo ye-epoxy efana nayo kufuneka ibrashwe kwaye itshizwe.
6.2 Umphakathi womzimba wevalvu kunye nawo onke amalungu epleyiti yevalvu kufuneka athintele ukubola ngokupheleleyo. Ngakolunye uhlangothi, ayiyi kuhlwa xa ifakwe emanzini, kwaye akukho ukubola kwe-electrochemical kuya kwenzeka phakathi kweentsimbi ezimbini; kwelinye icala, umphezulu ugudile ukunciphisa ukuxhathisa kwamanzi. i
6.3 Iimfuno zococeko ze-anti-corrosion epoxy resin okanye ipeyinti kwi-valve body kufuneka ibe nengxelo yovavanyo lwegunya elihambelanayo. Iipropati zekhemikhali kunye nezomzimba kufuneka zihlangabezane neemfuno ezifanelekileyo
7. Ukupakishwa kweValve kunye nokuthutha
