Muva nje, indawo yokusebenzela yakwaJinbin iqedele inqwaba yama-oda amavalvu ebhola ashiselwe ngokugcwele. Ii-valve yebhola eshiselwe ngokupheleleyamukela isakhiwo esihlanganisiwe esishiselwe. Umzimba we-valve wakhiwe ngokushisela ama-hemispheres amabili. Ingxenye yomgogodla wangaphakathi iyibhola elinendilinga embobeni, exhunywe ku-actuator yangaphandle ngesiqu se-valve. Lapho isebenza, i-ibhola valve flangeisiqu siqhutshwa ukuze sizungeze ngesibambo, i-gearbox noma idivayisi kagesi/yomoya.

Izinzuzo zokusebenzisa imboni ye-valve yebhola ehlanganiswe ngokugcwele:

1. Isakhiwo esinokwethenjelwa nokusebenza okuqinile kokubeka uphawu

Inqubo yokushisela iyonke iqeda izingozi zokuvuza kokuxhunywa kwe-flange evamile futhi ifanele izimo zokusebenza ezinzima ezifana nomfutho ophezulu, ukuvutha nokuqhuma (isibonelo, ukucindezela kwamapayipi egesi yemvelo kungafinyelela ngaphezu kuka-10MPa). Impahla yokuvala ayigugi futhi inempilo yesevisi engaphezu kweminyaka eyi-10, inciphisa imvamisa yokulungiswa.

2. Ukumelana nokugeleza okuphansi kanye nokuhamba okugcwele

I-spherical ngokusebenzisa imbobo ihambisana nobubanzi bangaphakathi bepayipi, futhi ukumelana nokugeleza kwe-medium yi-1/10 kuphela yepayipi yobude obufanayo, kunciphisa ukusetshenziswa kwamandla. Ilungele kakhulu ukuthutha okuhamba kakhulu (isibonelo, ububanzi bepayipi lepayipi likawoyela ongahluziwe lingafinyelela ku-1200mm).

3. Imelana nokugqwala futhi ivumelana nezimo ezindaweni ezinokhahlo

Umzimba we-valve yebhola engagqwali umbozwe ngensimbi engagqwali noma nge-carbon steel anti-corrosion coating (njenge-epoxy resin), engamelana nokugqwala kwenhlabathi nokuguguleka kwamanzi olwandle, futhi ifanele izimo eziyinkimbinkimbi njengendawo engaphansi komhlaba nangaphansi kwamanzi.

4. Kulula ukusebenza kanye nezindleko zokunakekela eziphansi

Ukuzungezisa okungu-90° kungaqeda ukuvula nokuvala. Kuhlanganiswe nesistimu yokulawula okuzenzakalelayo, isilawuli kude singafinyelelwa. Izakhiwo ezishiselwe zinciphisa izingxenye ezihambayo, zinezinga eliphansi lokuhluleka, futhi umjikelezo wokunakekela unganwetshwa ube ngaphezu kweminyaka emihlanu.

Izimo ezithile zohlelo lokusebenza lwevalvu yebhola enenjini eshiselwe ngokuphelele:

Isistimu yamapayipi amabanga amade

Ukudluliswa kwegesi yemvelo - esetshenziswa emigqeni yesiqu segesi yemvelo yasogwini (njengepayipi Legesi Esempumalanga-Empumalanga) kanye namapayipi okuhambisa igesi ngaphansi kolwandle, ingamelana nokucindezela okukhulu futhi iqinisekise ukuvaleka isikhathi eside ukuze kuvinjelwe izingozi zokuphepha ezibangelwa ukuvuza kwegesi yemvelo.

Ukuthutha uwoyela ongahluziwe/uwoyela ocolisisiwe - Ukulawula ukugeleza kwendawo ephakathi kumapayipi kawoyela awela umngcele, ukwakheka okugcwele kunciphisa ukugcinwa kukawoyela kanye nokwehla komfutho, futhi kuthuthukisa ukusebenza kahle kwezokuthutha.

2. Igesi yasemadolobheni kanye namanethiwekhi amapayipi okushisa

Igqitshwa futhi ifakwe epayipini elikhulu legesi elisedolobheni ukuze libhekane nokuxazululwa kwenhlabathi kanye nokushintsha kwezinga lokushisa kanye nokunciphisa ingozi yokuvuza. Lawula ukugeleza kwamanzi ashisayo ohlelweni lokushisa oluphakathi nendawo, futhi umelane nokucindezela okuphezulu (1.6MPa) kanye nezinga lokushisa eliphezulu (120℃).

3. Inkambu yezimboni

Imboni yamakhemikhali: Ukuthutha izinto ezonakalisayo njengama-asidi aqinile nama-alkali aqinile. Izinto zensimbi engagqwali kanye nezakhiwo zensimbi zokuvala kanzima ziqinisekisa ukuphepha (njengamapayipi e-hydrochloric acid namapayipi e-caustic soda).

I-Metallurgy namandla: Inganqamula ngokushesha ukugeleza kwegesi kumapayipi egesi yesithando somlilo noma ilawule izinga lokugeleza kwamapayipi amanzi okupholisa ezitshalo zamandla ashisayo, ijwayelane nezinga lokushisa eliphezulu (ngaphezulu kuka-300℃) kanye nezindawo ezinothuli.

4. Unjiniyela Wasolwandle kanye Nemikhumbi

Isetshenziswa kumapayipi kawoyela weplathifomu engasogwini namasistimu kaphethiloli womkhumbi, amelana nokugqwala kwamanzi olwandle futhi ekwazi ukumelana nokudlidliza kwemikhumbi, futhi ithobelana nezindinganiso zamazwe ngamazwe njenge-API 6D.

Ivalvu yebhola eshiselwe ngokugcwele i-Pn16, enokwethenjelwa kwayo okuphezulu, izindleko eziphansi zokunakekela kanye nokuvumelana nezimo ezibanzi, isibe ingxenye eyinhloko yokulawula ekudluliselweni kwamandla, izinqubo zezimboni nokwakhiwa kwengqalasizinda, ikakhulukazi engenakubuyiselwa ezinhlelweni zamapayipi amakhulu adinga ukusebenza okuzinzile isikhathi eside.
