IValve yeBhola yeMsonto yabasetyhini: Ulwakhiwo kunye neSingeniso seSicelo
Ivalve yebhola yomsonto yangaphakathi, eyaziwa ngokuba yivalve yebhola yomsonto yangaphakathi okanye ivalve yeglowubhu yebhola yomsonto yangaphakathi, luhlobo oluqhelekileyo lwevalve. Inqaku layo eliphambili kukuvula okanye ukuvala imijelo yamanzi ngokujikeleza i-90 degrees. Umgaqo wayo wokusebenza kukulawula ukuhamba kolwelo kwingqukuva. Xa ingqukuva ijikeleza ngokunxuseneyo kwi-axis yombhobho, ulwelo lunokudlula; Xa ingqukuva ijikeleza i-90 degrees perpendicular to the pipeline axis, inqumla ngokupheleleyo ukuhamba kolwelo.
Iimpawu zesakhiwo
Ivalve yebhola ephothiweyo yangaphakathi iqulathe ikakhulu la malungu alandelayo:
1. Umzimba wevalvu: Umzimba ongundoqo wevalvu, osetyenziselwa ukudibanisa imibhobho.
2. I-Sphere: Ifakwe ngaphakathi kumzimba wevalve, inokujikeleza ngokukhululekileyo kwaye ilawule ukuhamba kolwelo.
3. Isiqu sevalvu: sisitshixo esisetyenziselwa ukusebenzisa ibhola.
4. Isondo lesandla: lidla ngokufumaneka ekupheleni kwesinye isikhondo sevalve, esetyenziselwa ukujikelezisa isikhondo sevalvu ngesandla.
5. Izitywina: Qinisekisa ukuba ulwelo aluvuzi xa luvalekile.
Uyilo lwangaphakathi lomsonto luvumela le valve yebhola ukuba ikrwelwe ngokuthe ngqo kumbhobho, ukwenza ufakelo lube lula kwaye lukhawuleze. Ukongeza, ngenxa yesakhiwo sayo esilula, ubungakanani obuncinci, ubunzima obulula, kunye nokusebenza kakuhle kokutywinwa, iivalvu zebhola ezifakwe ngaphakathi zisetyenziswa ngokubanzi kwiinkqubo zemibhobho kumashishini afana nepetroleum, imichiza, isinyithi kunye namandla.
i-epilogue
Iivalvu zebhola ezinemisonto yangaphakathi ziyimfuneko kwaye zibalulekile izixhobo kuzo zombini iindawo zasekhaya nezamashishini. Ukuvela kwayo kuququzelele kakhulu imveliso yabantu kunye nobomi, inika inkxaso eyomeleleyo kuphuhliso loshishino lwanamhlanje.
