I-3PC Flanged Ball Valve ene-Direct Mounting Pad ASME 150lbs China Factory
Iyini i-valve yebhola yokufaka ngqo?
A I-valve yebhola yokufaka ngqo yebholakusho ukuthi ibhola livinjelwe ama-bearings futhi livunyelwe ukujikeleza kuphela, iningi lomthwalo we-hydraulic lisekelwa yizithiyo zeSistimu, okuholela ekucindezelweni okuphansi kwama-bearings kanye nokukhathala kwe-shaft.
Umfutho wepayipi ushayela isihlalo esingaphezulu ebholeni elingaguquki ukuze umfutho womugqa uphoqe isihlalo esingaphezulu ebholeni okubangela ukuthi livaleke. Ukubambelela kwebhola ngomshini kumunca ukusunduzwa okuvela kumfutho womugqa, kuvimbele ukungqubuzana okweqile phakathi kwebhola nezihlalo, ngakho-ke ngisho noma ingcindezi yokusebenza isezingeni eliphelele ihlala iphansi. Lokhu kunenzuzo ikakhulukazi lapho ivalvu yebhola iqhutshwa ngoba yehlisa usayizi we-actuator ngakho-ke izindleko eziphelele zephakheji ye-actuation yevalvu. I-trunnion iyatholakala kubo bonke osayizi kanye nazo zonke izinhlobo zomfutho kodwa ikakhulukazi ingezabosayizi abakhulu kanye nezimo zomfutho ophezulu.
Izici eziyinhloko ze-valve yebhola yokufaka eqondile ye-NORTECH
1. Ukuvimba Okubili Nokopha (DBB)
Uma ivalvu ivaliwe futhi umgodi ophakathi uthululwa ngevalvu yokukhipha amanzi, izihlalo ezingenhla nezingezansi zizovimba ngokuzimela. Omunye umsebenzi wedivayisi yokukhipha amanzi ukuthi isihlalo sevalvu singahlolwa uma kukhona ukuvuza ngesikhathi sokuhlolwa. Ngaphezu kwalokho, amadiphozithi emzimbeni angagezwa ngedivayisi yokukhipha amanzi. Idivayisi yokukhipha amanzi yakhelwe ukunciphisa umonakalo esihlalweni ngenxa yokungcola okungaphakathi.
4. Umklamo Wesakhiwo Ongashi
Uma kwenzeka umlilo ngesikhathi kusetshenziswa ivalvu, indandatho yesihlalo, indandatho yesiqu se-O kanye nendandatho ye-flange ephakathi ye-O eyenziwe nge-PTFE, irabha yezinye izinto ezingezona ezensimbi izobola noma yonakale ngaphansi kokushisa okuphezulu. Ngaphansi kwengcindezi ye-medium, ivalvu yebhola izosunduza i-seat retainer ngokushesha iye ebholeni ukuze yenze indandatho yensimbi ixhumane nebhola futhi yakhe isakhiwo sokuvala insimbi esisekelayo kuya kwensimbi, esingalawula ngempumelelo ukuvuza kwevalvu. Umklamo wesakhiwo esingashisi umlilo se-trunnion pipeline ball valve uhambisana nezidingo eziku-API 607, API 6FA, BS 6755 kanye nezinye izindinganiso.
13. Isiqu Sokwelulwa
Ngokuphathelene nevalvu ehlanganisiwe, isiqu sokwelula singanikezwa uma kudingeka ukusebenza komhlabathi. Isiqu sokwelula sakhiwe ngesiqu, ivalvu yokujova ye-sealant, kanye nevalvu yokukhipha amanzi enganwetshwa iye phezulu ukuze kube lula ukusebenza. Abasebenzisi kufanele babonise izidingo zesiqu sokwelula kanye nobude lapho bebeka ama-oda. Kuvalvu yebhola eqhutshwa nge-actuators kagesi, yomoya kanye neyomoya - ye-hydraulic, ubude besiqu sokwelula kufanele busuke enkabeni yepayipi kuya ku-flange ephezulu.
6. Isakhiwo sokuvala isihlalo esithembekile
Ukuvalwa kwesihlalo kutholakala ngokusebenzisa izibambi zezihlalo ezimbili ezintantayo, Zingantanta nge-axial ukuvimba uketshezi, okuhlanganisa ukuvalwa kwebhola kanye nokuvalwa komzimba. Ukuvalwa kwesihlalo se-valve ngengcindezi ephansi kutholakala ngokuqiniswa kwentwasahlobo. Ngaphezu kwalokho, umphumela we-piston wesihlalo se-valve uklanywe kahle, okwenza ukuvalwa kwengcindezi ephezulu kutholakale ngengcindezi ye-medium uqobo. Izinhlobo ezimbili ezilandelayo zokuvalwa kwebhola zingabonakala.
7. Ukuvalwa Okukodwa
(Ukukhululeka Kokucindezela Okuzenzakalelayo Emgodini Ophakathi Wevalvu) Ngokuvamile, kusetshenziswa isakhiwo esisodwa sokuvala. Okusho ukuthi, kukhona ukuvala okuphezulu kuphela. Njengoba kusetshenziswa izihlalo zokuvala ezizimele ezithwele intwasahlobo ephezulu kanye nephansi, umgodi wevalvu ongaphakathi ocindezela kakhulu unganqoba umphumela wokuqinisa wentwasahlobo, ukuze isihlalo sikhululwe ebholeni futhi sithole ukukhululeka kokucindezela okuzenzakalelayo engxenyeni engezansi. Uhlangothi oluphezulu: Lapho isihlalo sihamba nge-axial eceleni kwevalvu, ingcindezi ethi “P” esetshenziswa engxenyeni ephezulu (i-inlet) ikhiqiza amandla angemuva ku-A1, Njengoba i-A2 iphakeme kune-A1, i-A2-A1=B1, amandla ku-B1 azosunduza isihlalo siye ebholeni futhi athole ukuvalwa okuqinile kwengxenye ephezulu.
Uhlangothi olungezansi: Uma ingcindezi ethi “Pb” ngaphakathi kwe-valve Cavity ikhula, amandla asetshenziswa ku-A3 aphakeme kunalawo aku-A4. Njengoba i-A3-A4=B2, umehluko wengcindezi ku-B2 uzonqoba amandla entwasahlobo ukuze isihlalo sikhululwe ebholeni futhi kutholakale ukukhululeka kwengcindezi ye-valve engxenyeni engezansi ngemuva kwalokho, isihlalo nebhola kuzovalwa futhi ngaphansi kwesenzo sentwasahlobo.
Ukuvalwa kwesibili: Ngaphansi komfula.
Uma umehluko wokucindezela uphansi noma kungekho umehluko wokucindezela, isihlalo esintantayo sizohamba nge-axial eceleni kwevalvu ngaphansi kwesenzo sentwasahlobo bese sisunduza isihlalo siye ebholeni ukuze sigcine ukuvala okuqinile. Lapho ukucindezela kwesikhala sevalvu u-P kukhuphuka, amandla asebenza endaweni engu-A4 yesihlalo sevalvu ephakeme kunamandla asebenza endaweni engu-A3,A4-A3=B1. Ngakho-ke, amandla aku-B1 azosunduza isihlalo siye ebholeni futhi aqinisekise ukuvalwa okuqinile kwengxenye ephezulu.
9. Idivayisi Yokusiza Ukuphepha
Njengoba ivalvu yebhola yakhelwe ngokuvalwa okuphambili nokwesibili okuthuthukisiwe okunomphumela wepiston ephindwe kabili, futhi umgodi ophakathi awukwazi ukukhulula ingcindezi ngokuzenzakalelayo, ivalvu yokukhulula ukuphepha kumele ifakwe emzimbeni ukuze kuvinjelwe ingozi yokulimala ngokweqile ngaphakathi komgodi wevalvu okungenzeka ngenxa yokwanda kokushisa kwe-medium. Ukuxhumeka kwevalvu yokukhulula ukuphepha ngokuvamile kuyi-NPT 1/2. Elinye iphuzu okufanele liqashelwe ukuthi umgodi wevalvu yokukhulula ukuphepha ukhishwa ngqo emoyeni. Uma ukukhishwa ngqo emoyeni kungavunyelwe, siphakamisa ukuthi ivalvu yebhola enesakhiwo esikhethekile sokukhulula ingcindezi ngokuzenzakalelayo iye emfuleni ongaphezulu kufanele isetshenziswe. Bheka okulandelayo ukuze uthole imininingwane. Sicela ukubonise ngokulandelana uma ungayidingi ivalvu yokukhulula ukuphepha noma uma ungathanda ukusebenzisa ivalvu yebhola enesakhiwo esikhethekile sokukhulula ingcindezi ngokuzenzakalelayo iye emfuleni ongaphezulu.
Umdwebo oyinhloko we-ball valve yokuvala phezulu naphansi komfula
Umdwebo oyisisekelo wokukhululeka kwengcindezi ye-ball valve cavity ukuya ekufakweni komfudlana ongaphezulu kanye nokuvalwa komfudlana ophansi
12. Ukumelana Nokugqwala Nokumelana Nokucindezeleka Kwe-Sulfide
Kusele imvume ethile yokugqwala kobukhulu bodonga lomzimba.
Isiqu sensimbi yekhabhoni, umgodi oqinile, ibhola, isihlalo kanye nendandatho yesihlalo kufakwe i-nickel plating yamakhemikhali ngokuya nge-ASTM B733 kanye ne-B656. Ngaphezu kwalokho, izinto ezahlukahlukene ezingamelana nokugqwala ziyatholakala ukuze abasebenzisi bazikhethe. Ngokwezidingo zamakhasimende, izinto ze-valve zingakhethwa ngokuya nge-NACE MR 0175 / ISO 15156 noma i-NACE MR 0103, futhi ukulawulwa kwekhwalithi okuqinile kanye nokuhlolwa kwekhwalithi kufanele kwenziwe ngesikhathi sokukhiqiza ukuze kuhlangatshezwane ngokugcwele nezidingo ezindinganisweni futhi kuhlangatshezwane nezimo zesevisi endaweni ye-sulfurization.
