Uma ubuqotho nokuphepha kohlelo kungaxoxiswana ngakho ngaphansi kwengcindezi enkulu, ukukhetha i-valve kuba yisinqumo esibalulekile sobunjiniyela.Amavalvu Ebhola Eliphezulu Lokucindezelazenzelwe ngqo ukusebenza lapho ama-valve ajwayelekile engahluleka khona. Lo mhlahlandlela uhlola ukuthi yini ehlukanisa lezi zingxenye eziqinile, izici zazo ezibalulekile zokuklama, nokuthi ungakhetha kanjani efanele imisebenzi yakho enzima kakhulu.
Iyini i-High Pressure Ball Valve?
A I-High Pressure Ball Valveiyivalvu ekhethekile yokujika kwekota eyenzelwe ukuhlukanisa nokulawula ukugeleza kwemidiya enamandla ezinhlelweni ezivame ukusebenza ngaphezu kwe-10,000 PSI (690 bar). Ngokungafani namavalvu ebhola ajwayelekile, abonakala ngokwakhiwa kwawo okunzima, izindlela zokuvala ezithuthukisiwe, kanye nezinto ezikwazi ukumelana nokucindezeleka okukhulu kwemishini nokushisa ngaphandle kokubeka engcupheni ukusebenza noma ukuphepha.
Izici Eziyinhloko Zokuklama Ezihlukanisa Ama-Valve Ebhola Elinomfutho Ophakeme
Ikhono lokusingatha ingcindezi enkulu akuyona indaba yengozi; kungumphumela wobunjiniyela obuhlosiwe nobunembile. Nazi izinto ezibalulekile zokuklama:
Umzimba Oqinisiwe Nokwakhiwa Okuqinile:
Lawa ma-valve avame ukuba nomzimba omncane, ohlanganisiwe owenziwe ngezinto ezinamandla aphezulu njengensimbi engagqwali (SS304, SS316), insimbi engagqwali ephindwe kabili, noma insimbi ye-chromium-molybdenum (A105). Ukuhlanganisa kunikeza isakhiwo esihle kakhulu sokusanhlamvu, okuthuthukisa amandla omshini we-valve kanye nokumelana nokushayisana.
Umklamo Wesiqu Esinomfutho Ophakeme:
Isiqu siqiniswa ukuze kuvinjelwe ukuqhuma ngaphansi kwengcindezi. Isiqu esiqinile, esivame ukuba nomklamo ovikela ukuqhuma, siqinisekisa ukuthi ingcindezi yangaphakathi ayikwazi ukuphoqa isiqu ukuba siphume emzimbeni wevalvu, okuyisici esibalulekile sokuphepha.
Izinhlelo Zokuvala Ezithuthukisiwe:
Lena inhliziyo yevalvu yebhola enomfutho ophezulu.
• Izihlalo Ezingashayisani Kakhulu:Kusetshenziswa izihlalo ezenziwe nge-PTFE eqinisiwe (RPTFE), i-PEEK (i-Polyether Ether Ketone), noma insimbi. Lezi zinto zigcina ubuqotho bazo bokuvala futhi zinokungqubuzana okuncane ngesikhathi sokusebenza, ngisho noma kunamandla amakhulu.
• Izihlalo Ezigcwele Intwasahlobo:Imiklamo eminingi yokucindezela okuphezulu ifaka izihlalo ezifakwe entwasahlobo. Izipringi zisebenzisa amandla aqhubekayo okulayisha isihlalo, ziqinisekisa ukuvala okuqinile ngokumelene nebhola kokubili ekucindezelekeni okuphansi kanye nokuphezulu, futhi zikhokhela ukuguguleka ngokuhamba kwesikhathi.
Imbobo Encishisiwe vs. Imbobo Egcwele:
Nakuba amavalvu agcwele anikeza ukumelana nokugeleza okuphansi, izinhlelo zokusebenza ezicindezela kakhulu zivame ukusebenzisa imiklamo ye-reduced-port (noma i-standard-port). Udonga olujiyile oluzungeze i-port encane lwandisa ikhono le-valve lokulawula ukucindezela, okuwukushintshana okudingekayo ukuze kuphephe kakhulu.
Izicelo Ezibalulekile Zama-High Pressure Ball Valve
Lawa ma-valve abalulekile ezimbonini lapho ukwehluleka kwesistimu kungeyona inketho:
•Uwoyela negesi:Ukulawula i-Wellhead, izinhlangano zesihlahla sikaKhisimusi, amayunithi okuqhekeka kwe-hydraulic (fracking), kanye nemigqa yokudlulisa igesi enomfutho ophezulu.
•Ukukhiqizwa Kwamandla:Imigqa emikhulu yomusi, izinhlelo zamanzi okuphakelwa, kanye nezinye izifunda ezibalulekile zokucindezela okuphezulu/zokushisa ezitshalweni ezishisayo nezenuzi.
•Amakhemikhali kanye ne-Petrochemical:Ukuphatha ama-catalyst anamandla, ama-reactor anomfutho ophezulu, kanye nezinhlelo zokujova.
•Ukusika Ijethi Yamanzi:Ukulawula amanzi anomfutho ophezulu kakhulu (afinyelela ku-90,000 PSI) asetshenziswa ezinhlelweni zokusika zezimboni.
•Ama-Rig Okuhlola Okunomfutho Ophakeme:Ukuqinisekisa ubuqotho bezinye izingxenye ezifana namapayipi, izinto zokufaka, namavalvu.
Indlela Yokukhetha I-Valve Yebhola Eliphezulu Elifanele
Ukukhetha ivalvu efanele kuyinqubo enezici eziningi. Cabanga ngalezi zici:
1. Isilinganiso Sokucindezela (i-PSI/Ibha):
Qinisekisa ukuthi ingcindezi yokusebenza ephezulu kakhulu (WP) yevalvu kanye nesilinganiso sokucindezela (isb., i-ANSI Class 1500, 2500, 4500) idlula ingcindezi yokusebenza ephezulu kakhulu yesistimu yakho, kufaka phakathi noma yiziphi izingcindezi zokunyuka kwamandla ezingaba khona.
2. Ububanzi Bezinga Lokushisa:
Qinisekisa ukuthi isihlalo nezinto zokuvala ziyahambisana namazinga okushisa aphansi naphezulu esistimu yakho.
3. Ukuhambisana kwezinto ezibonakalayo:
Umzimba wevalvu, uthayela, kanye nezivalo kumele kuhambisane nemidiya (uketshezi noma igesi) ukuvimbela ukugqwala nokuwohloka. Cabangela izici ezifana nama-chloride, okuqukethwe yi-H2S, kanye namazinga e-pH.
4. Ukuxhumana Okuphelele:
Khetha kusukela ekuxhumekeni okuqinile njenge-threaded (NPT), i-socket weld, noma i-butt weld, ukuqinisekisa ukuthi zilungele isheduli yepayipi kanye nezinto zokwakha.
5. Umklamo Ophephile Emlilweni:
Ngezicelo zikawoyela negesi, izitifiketi ezifana ne-API 607/API 6FA ziqinisekisa ukuthi ivalvu izoqukatha imidiya uma kwenzeka umlilo.
6. Ukusebenza:
Ngezinhlelo ezenzakalelayo, qiniseka ukuthi ivalvu iklanyelwe ukuhlangana nama-actuator omoya noma kagesi angakhiqiza i-torque eyanele ukusebenza ngaphansi kwengcindezi ephelele yesistimu.
Kungani Kufanele Usebenzisane Nomkhiqizi Ochwepheshe?
Kwa-NSW Valve, siyaqonda ukuthi ivalvu yebhola enomfutho ophezulu ingaphezu nje kwengxenye; kuyisibopho sokuphepha nokusebenza kahle. Amavalvu ethu aklanywe ngokugxila ku:
•Ukwakha Nokukhanda Ngokunembile ukuze kube nobuqotho besakhiwo obungenakuqhathaniswa.
•Izinqubo Zokuhlola Eziqinile, okuhlanganisa nokuhlolwa kwegobolondo elinomfutho ophezulu kanye nesihlalo, okuqinisekisa ukuthi yonke ivalvu isebenza njengoba kuchaziwe.
•Isiqondiso Sokukhetha Izinto Ezikhethekile ukuze sihambisane nendawo yakho yokusebenza ethile.
