I-Valve Yebhola Eshiselwe Ngokugcwele
Incazelo Yomkhiqizo
Ibhola le-valve yebhola elintantayo lisekelwa ngokukhululekile eringini yokuvala. Ngaphansi kwesenzo sokucindezela koketshezi, ixhunywe eduze nendandatho yokuvala engezansi komfula ukuze yakhe isivalo esisohlangothini olulodwa esinyakazayo esingezansi komfula. Ifanele izikhathi zezinga elincane.
Ibhola le-valve yebhola elungisiwe eline-shaft ejikelezayo eya phezulu naphansi, igxilile endaweni ephethe ibhola, ngakho-ke, ibhola ligxilile, kodwa indandatho yokuvala iyantanta, indandatho yokuvala enomfutho we-spring kanye ne-fluid thrust ebholeni, ekupheleni komfula. uphawu.Isetshenziselwa ukucindezela okukhulu kanye nezicelo zezinga elikhulu.
Ingxenye yokushayela ye-valve ngokuya ngesakhiwo se-valve kanye nezidingo zomsebenzisi, usebenzisa isibambo, i-turbine, ugesi, i-pneumatic, njll., ingasekelwe esimweni sangempela kanye nezidingo zomsebenzisi ukuze ukhethe imodi yokushayela efanele.
Lolu chungechunge lwemikhiqizo ye-valve yebhola ngokusho kwesimo se-medium nepayipi, kanye nezidingo ezahlukene zabasebenzisi, umklamo wokuvimbela umlilo, i-anti-static, njengesakhiwo, ukumelana nokushisa okuphezulu kanye nokushisa okuphansi kungaqinisekisa ukuthi i-valve ngaphansi kwezimo ezahlukene ngokuvamile umsebenzi, esetshenziswa kabanzi igesi yemvelo, uwoyela, imboni yamakhemikhali, metallurgy, ukwakhiwa kwamadolobha, ukuvikelwa kwemvelo, imithi, ukudla kanye nezinye izimboni.
