Izolo, iqembu leamavalvu ebhola ahlanganisiwekusuka ku-Jinbin Valve kwapakishwa futhi kwathunyelwa.

I-valve yebhola yokushisela ngokugcwele iwuhlobo lwe-valve yebhola enesakhiwo somzimba se-valve yebhola yokushisela ngokugcwele. Ifinyelela ekuphumeni kwe-medium ngokujikeleza ibhola ngama-90° kuzungeze i-axis ye-valve stem. Isici sayo esiyinhloko ukuthi zonke izingxenye zomzimba we-valve zixhunywe ngokuphelele ngobuchwepheshe bokushisela, ngaphandle kwezakhiwo zokuxhuma ezisuswayo njenge-flanges noma izintambo. Ukusebenza kwayo kokuvala kanye namandla esakhiwo kungcono kakhulu kunezinhlobo zokuxhuma zendabuko zama-valve ebhola. Ifanele izimo zokuthutha zemidiya efana namanzi, igesi, uwoyela kanye noketshezi oluhlukahlukene olubolayo.

Izinzuzo zokushintshwa ngokupheleleImboni ye-ball valvekubonakala kakhulu ezicini ezintathu:

1. Inamandla kakhulu okuvala uphawu.

Ngenxa yokungabikho kwendawo yokuvala exhunywe kwi-flange, igwema izingozi zokuvuza ezibangelwa amabhawodi axegayo kanye nezingxenye zokuvala ezigugile kuma-valve ebhola axegayo avamile, okwenza ifaneleke kakhulu ezidingweni zokuphepha lapho kuthuthwa izinto ezivuthayo, eziqhumayo, ezinobuthi noma ezinomfutho ophezulu.

2. Isakhiwo siqinile futhi sithembekile.

Isakhiwo esihlanganisiwe siphelele sinokumelana okumangalisayo komthelela kanye nokumelana nokudlidliza, futhi singazivumelanisa nokucindezela okuphezulu (kufika ku-10MPa nangaphezulu), izinga lokushisa eliphezulu (-29℃ kuya ku-300℃), ngaphansi komhlaba kanye nomswakama kanye nezinye izindawo ezinzima. Ukuqina kwaso kuphakeme kakhulu kunokwemizimba yamavalvu ahlukene.

Okwesithathu, izindleko zokulungisa ziphansi. Isakhiwo esishisiwe sinciphisa izingxenye ezisengozini futhi asidingi ukuqinisa njalo amabhawodi. Isikhathi saso senkonzo singafinyelela amashumi eminyaka amaningana, kunciphisa kakhulu imvamisa yezindleko zokulungisa kamuva kanye nesikhathi sokungasebenzi. Ngesikhathi esifanayo, umklamo omncane ungasindisa nendawo yokufaka.

Izimo ezivamile zama-valve ebhola ahlanganiswe ngokugcwele zigxile kakhulu emasimini anezidingo eziphezulu kakhulu zokuvala ukusebenza, ukuphepha kanye nokuqina kwesikhathi eside (Uhlelo Lokusebenza Lwe-Ball Valve):

Emapayipini kawoyela negesi ahamba ibanga elide, kuyingxenye yokulawula eyinhloko yokubeka ngaphansi komhlaba, ekwazi ukumelana nokugqwala kwenhlabathi kanye nezinguquko zejiyoloji, okuqinisekisa ukuphepha kokuthuthwa kukawoyela negesi ahamba ibanga elide.

Kumanethiwekhi okushisa kagesi asemadolobheni kanye nendawo eyodwa, ukumelana kwawo nomfutho ophezulu kanye nezici zokuvuza okuphansi kunganciphisa ngempumelelo ukulahleka kwamandla kanye nezingozi zokuphepha.

Emigqeni yenqubo yezimboni ze-petrochemical kanye namakhemikhali, ifanele ukuthutha izinto ezigqwalisayo, ezivuthayo neziqhumayo, ihlangabezana nezidingo zezimo zokusebenza ezinzima.

Ngaphezu kwalokho, isetshenziswa kabanzi emipayipini yokudlulisa amanzi enomfutho ophezulu yamaphrojekthi okulondolozwa kwamanzi kanye nezinhlelo ezikhethekile zokuthutha uketshezi emkhakheni omusha wamandla ngenxa yokuthembeka kwayo okuqinile.

Amavalvu ebhola ahlanganiswe ngokuphelele, anamandla awo “okungavuzi lutho” kanye nokuqina kwawo, abe yimishini ekhethwayo yezimo zokulawula uketshezi olunomfutho ophezulu kanye nolunobungozi obukhulu. Amavalvu e-Jinbin abe ngochwepheshe ekukhiqizeni amavalvu iminyaka engama-20. Uma unezidingo ezihlobene, sicela usithinte ngezansi futhi uzothola impendulo zingakapheli amahora angama-24!
