Ngokukodwa iinkqubo zeekhemikhali ulwelo olukwimibhobho luhlala luyityhefu, lusebenza ngeradioactive kwaye luyingozi.Iivalvu zesango lokutywinwa kweBellowszisetyenziselwa ukuthintela ukuvuza kwayo nayiphi na imichiza eyityhefu emoyeni.Isixhobo somzimba sinokukhethwa kuzo zonke izixhobo ezikhoyo, I-bellow inokunikezelwa ngezinto ezahlukeneyo ezifana ne-316Ti, 321, C276 okanye i-Alloy 625.

• 1) .Iintsimbi zentsimbi zitywina isiqu esishukumayo kwaye kwandisa ukuqina kweevalvu ezipakishiweyo zokutywina.
• 2) .Izibuko zokubeka iliso zeBellows (ukhetho): Iplagi inokudityaniswa kunye nesithuba esingentla kwemvulo ukujonga ukusebenza.
• 3) .Amatywina amabini esibini: a) Isitulo sangasemva kwindawo evulekileyo;b) Ukupakishwa kwegrafu.
• 4).yeBellows ivalve yesango lokutywina, iinxalenye zayo eziphambili zentsimbi, isiphelo esisezantsi kunye nesiqu sevalvu ziqengqeleka ngokuzenzekelayo, kwaye isiphelo esiphezulu kunye netyhubhu yokukhusela i-welded roll ezenzekelayo ngokunjalo.Umqobo wesinyithi wenziwa phakathi kwesiqu kwindawo yayo yokungena ngomda woxinzelelo kunye nenkqubo yolwelo ngaphakathi kwevalve, ukuphelisa ukuvuza kwesiqu;
• 5) .Iivalve ezivalwe ngeBellow-sealed zivame ukuvuza zivavanywa kusetyenziswa i-spectrometer enkulu ukubona amazinga okuvuza angaphantsi kwe-1x10E-06 std.cc/sec.Uyilo lokutywinwa kabini (i-bellows seal kunye nokupakishwa kwesiqu) ukuba i-bellows ayiphumelelanga, ukupakishwa kwe-valve stem kuya kuphepha. ukuvuza, kunye nokuhambelana nemigangatho yokuqina yamazwe ngamazwe;
• 6).Iibhonethi ezivaliweyo zifakwe nge-bellow-sealed kunye ne-standard stem packing set kunye ne-port esweni yokuvuza phakathi kwe-bellows kunye nokupakisha ukuze kuthintelwe ukukhutshwa okuyingozi kolwelo oluyingozi xa kukho ukuvuza kwemvula.
• 7).Kungekhona njengesikrufu segrisi samandulo kumsonto wesiqu kuphela, Ingono yegrisi yenzelwe kwibhonethi yevalvu, sinokuthambisa isiqu, i-nut kunye ne-bushing ngqo, ngengono yegrisi;
• 8) .I-handwheel eyenzelwe i-ergonomically, ubomi benkonzo ende, kulula ukuyisebenzisa, ikhuselekile kwaye inokwethenjelwa ngakumbi;
