Ivalvu igama elijwayelekile lezingxenye zokulawula eziphambukisa, ezinqamule futhi zilawule uketshezi
Umlando wemboni ye-valve
Ukulandela emuva kumsuka wevalvu, kufanele kulandelelwe emuva entweni yokhuni emanxiweni aseGibhithe lasendulo okwakucatshangwa ukuthi ivalvu ngo-1000 AD. Enkathini yamaRoma asendulo, kakade kwase kunezindawo zamapayipi ezindlini zezicukuthwane namavalvu ethusi ayezothunyelwa kwamanye amazwe.
Kamuva, ubuchwepheshe be-valve nabo bathuthukiswa. Ngokuthuthukiswa kobuchwepheshe bokukhiqiza ama-valve ensimbi, kwamukelwa izindlela ezintsha zokuphonsa futhi izinto zokwakha zathuthukiswa. I-valve yensimbi yamukela imishini yokusebenza enamandla, futhi ukunemba nakho sekuthuthukisiwe.
Ukuze kubhekwane nokushoda kwamanzi kwamapayipi okwakha, imithethonqubo yomsindo ehlobene nezinsiza zomkhiqizo, kanye nokuthuthukiswa kokuphepha kwegesi, amavalvu ahlanganisa ama-valve avimbela ukugqwala amapayipi okuhambisa amanzi, ama-valve anomsindo omncane okwehlisa umsindo wokugeleza, ompompi abanezisekelo, kanye ukuhlanganisa. Ukuguqulwa kwamapulaki egesi kasilika.
Manje sethuleimishini ye-valve ekhethekilefuthiumshini wokulungisa i-valveengakwenza lokhu. Ngemuva kokuthuthukiswa okuningana, umthamo wamanje wethuluzi lokusika ungafika ku-10mm. Isebenza kahle, ikahle, izinzile futhi inokwethenjelwa. Inikezelwe ekucubunguleni insimbi eyenziwe ngomgunyathi, insimbi ekhonjiwe, amavalvu esango, ama-globe valves, ama-Butterfly valves, izindololwane, njll.
