Amavalvu e-Triple Offset Butterfly amavalvu asebenzisa ipuleti lovemvane lohlobo lwe-disc ukuzungeza okungu-90 ° emuva naphambili ukuze avule, avale noma alungise okuphakathi ukuze alawule ukugeleza.Abanayo nje isakhiwo esilula, ivolumu encane, isisindo esincane, ukusetshenziswa kwempahla ephansi, usayizi omncane wokufaka, i-torque encane yokushayela, ukusebenza okulula nokusheshayo, kodwa futhi nomsebenzi omuhle wokulawula ukugeleza nezici zokuvala zokuvala.I-Triple Offset Butterfly Valves isetshenziswa kabanzi kwezensimbi, amandla kagesi, imboni ye-petrochemical, ukuhlinzekwa kwamanzi kanye ne-drainage, ukwakhiwa kukamasipala namanye amapayipi ezimboni anezinga lokushisa eliphakathi ≤ 425 ℃.Zisetshenziselwa ukulawula ukugeleza nokusika uketshezi.
Izici eziyinhloko zokwakha zeI-JLPVI-valve ye-butterfly eyi-triple offset ilandelayo:
1. Isakhiwo se-eccentric emithathu kanye nokusebenza kokuvala okukabili
I-axis ye-valve stem ichezuka esikhungweni se-disc kanye nesikhungo somzimba ngesikhathi esifanayo, futhi i-axis yokuzungeza yesihlalo se-valve ine-engeli ethile ne-axis yesiteshi yomzimba we-valve.I-disc seal ithintana nesihlalo se-valve kuphela lapho sisendaweni evaliwe, okwenza isihlalo se-valve nepuleti levemvane kucishe kungagugi.Amandla e-torque akhiqizwa ngesikhathi senqubo yokuvala, okwenza isihlalo se-valve sibe nomsebenzi wokuvala wokuvala ngokuqinile.
2. Isihlalo se-valve uvemvane kathathu yisihlalo somzimba noma isihlalo esiyimbondela, esenziwe ngezinto ezahlukene.
Isakhiwo sesihlalo somzimba se-triple offset butterfly valve ukufaka isihlalo emzimbeni.Uma kuqhathaniswa ne-disc nesihlalo, kunciphisa kakhulu ithuba lesihlalo sokuxhumana nomuntu ophakathi ngokuqondile, ngaleyo ndlela kunciphise izinga lokuguguleka nokwandisa impilo yesevisi yesihlalo.Inqubo yokuvela kwe-valve ye-butterfly ephindwe kathathu yenziwa ngokuhambisana ngokuqinile nenqubo yokushisela evunyelwe i-WPS standard.Ngemuva kokuvela, ukwelashwa kokushisa, ukukhanda imishini, ukuhlanzwa okuphelele nokuhlolwa kuzokwenziwa endaweni ye-welding ngokuya ngezidingo ngaphambi kokuhlangana.
3. Umklamo wesihlalo ongashintshwa
Isihlalo se-valve sakhiwe ishidi lensimbi engagqwali kanye neshidi le-graphite.Lesi sakhiwo singavimbela ngokuphumelelayo ithonya lezinto ezincane eziqinile phakathi nendawo kanye nokuzibandakanya kwendawo yokuvala okubangelwa ukwanda kokushisa.Ngisho noma kunomonakalo omncane, ngeke kube khona ukuvuza.
4. I-Anti-flying stem design
Ukupakishwa kwesiqu akulula ukonakala futhi ukubekwa uphawu kunokwethenjelwa.Ilungiswa ngephinikhodi ye-taper yediski, futhi isiphetho sesandiso siklanyelwe ukuvimbela isiqu ekuqhumeni lapho induku ye-valve iphuka ngephutha ekuxhumekeni kwenduku ye-valve kanye nepuleti levemvane.
5. Isihlalo: uphawu oluthambile noluqinile
Ibanga lomklamo we-JLPV Triple Offset Butterfly Valve limi kanje:
1. Usayizi: 2” kuya ku-96” DN50 kuya ku-DN2400
2. Ingcindezi: Ikilasi 150lb ukuya ku-900lb PN6-PN160
3. Material: carbon steel, insimbi engagqwali nezinye izinto ezikhethekile.
I-NACE MR 0175 anti-sulphur kanye nezinto zensimbi ezilwa nokugqwala.
4. Ukuxhumana kuyaphela: I-Flange, I-Wafer, Uhlobo Lwe-Lug ngokusho kwe-ASME B 16.5
I-ASME B 16.25 kuma-butt welding ends.
5. Ubukhulu bobuso nobuso: buhambisana ne-ASME B16.10
6. Izinga lokushisa: -29℃ ukuya ku-425 ℃
Ama-valve e-JLPV angafakwa ama-gear operator, ama-pneumatic actuators, ama-hydraulic actuators, ama-actuator kagesi, izinto zokukhiya, amasondo amaketanga, iziqu ezinwetshiwe nokunye okuningi kuyatholakala ukuze kuhlangatshezwane nezidingo zamakhasimende.
