Yini izidingo zokufaka ama-butterfly valves?

Ukufakwa kweama-ama-ama-butterfly valvesKumele ulandele ngokuqinile imininingwane yokusebenza, futhi ukulawulwa ngokucophelela kuyadingeka kusuka ekuhlelweni kusenesikhathi ukufakwa nokuthunyelwa. Okulandelayo izidingo ezithile:

Ukulungiselela ngaphambi kokufakwa kudinga ukuqina: ngaphambi kokufakwa, imodeli ye-valve ye-butterfly kanye nokucaciswa kudinga ukuhlolwa ukuze kuqinisekiswe ukuhambisana nohlelo lwamapayipi, kufaka phakathi isilinganiso sengcindezelo, izinga eliphakathi nendawo, izinga lokushisa kanye namanye amapharamitha. Ngasikhathi sinye, hlanza kahle ingaphakathi lepayipi, ususe i-welding slag, ukungcola, kanye nezinto zakwamanye amazwe ukuvimbela ukulimala endaweni yokubekwa uphawu. Ngaphezu kwalokho, kuyadingeka ukuqinisekisa ukukhonjwa kokugeleza kwe-Flow Rection yeVitterfly valve ukuqinisekisa ukuthi inkomba yokufaka iyahambisana nokuqondiswa kokugeleza kwe-medium. Imvamisa, kukhona imicibisholo ekhombisa emzimbeni we-valve ukugwema ukufakwa okuguqukayo okuthinta ukusebenza kokubekwa uphawu.

Kunezidingo zesikhundla sokufaka nesiqondisi: Ama-butterfly ama-valves angafakwa ngokuvundlile noma ngokuqondile, kepha kuyadingeka ukuqinisekisa ukuthi i-valve Plate rotation rotation i-axis ye-Pipendine, futhi kunesikhala esanele sokuqondiswa kwe-Pipeline noma kagesi kwesiqondisi sokusebenza kwe-Valve Stem.Ama-butterfly valveskufanele kugwenywe ukuthi kufakwe ekufakweni kwamapayipi noma ezindaweni zokugxila kwengcindezelo ukuvimbela ukuvuza okubangelwa ukudlidliza noma ukucindezela okungalingani. Ama-valves we-Butterfly kagesi noma we-pneumatic, kuyadingeka ukuhlola ukuhambisana phakathi kwe-actuator ne-valve, bese ulungisa umkhawulo wesifo sohlangothi ukuze ugweme ukulonda ngokweqile. Uma i-medium inguketshezi olushisa kakhulu, ukuwohloka noma udaba oluphezulu, kuyadingeka ukuthi ukhethe izinto zokubopha ezivimbela izinga lokushisa eliphakeme kanye nokugqwala okufana nama-valves wensimbi.

Inqubo yokufaka kufanele ibe ngokuqondile: Ama-Flange Bolts kufanele aqiniswe ngokulinganayo ukuze agweme ukubekwa uphawu okunganele okubangelwa amandla anecala elilodwa. Kunconywa ukusebenzisa i-torque wrench ukuze usebenze ngokuya nge-torque ejwayelekile. I-gasket evuthayo ye-flange kufanele yenziwe ngezinto zokwakha ezihambelana ne-medium, njengerabha, i-polytetrafluoroethlelene, njll., Ukuvimbela ukugqwala noma ukwehluleka okushisa okuphezulu. Ngemuva kokufaka, i-valve yevemvane idinga ukuvulwa ngesandla futhi ivalwe amahlandla amaningi ukuqinisekisa ukuthi iplate ye-valve ijikeleza kalula ngaphandle kokuvinjelwa. Ama-valves wevemvane kagesi, ukushaywa kanye nokuvalwa kwendlela yokulawula kulungiswe ngaphambi kokushiya ifektri. Ukuvimbela amaphutha afundisayo lapho amandla evuliwe, abasebenzisi kufanele bavule ngesandla i-valve ibe yisigamu sesigamu ngaphambi kokuvula amandla, bese becindezela inkinobho kagesi ukuze ubheke ukuthi ingabe indlela evulwa yi-valve.

Ukulungiswa okulandelayo kubalulekile: Ukulungiswa okujwayelekile kunganweba isikhathi sokuphila kweama-ama-ama-butterfly valves, njengokuthambisa iziqu ze-valve kanye nokuhlola izimpawu. Uma kutholakala ukuvuza i-valve, kuyadingeka ukuhlola ukuthi ngabe indandatho yokuvala uphawu iyaguga noma igqokwa, nokuthi ama-flts ama-flange akhululiwe; Uma ipuleti le-valve livinjelwe, lingaba ngenxa yokungcola noma ukugqwala emgodini we-valve, bese kuthathwa isiqu se-valve bese kugcotshwa.
