Kwindawo yokucima umlilo, iValves idlala indima ebalulekileyo ekulawuleni ukuhamba kwamanzi okanye ezinye iiarhente zokucima umlilo. Iindidi ezimbini zeVolves ezisetyenziswayo kule ntsimi ziivalves zebhabhathane kunye neevalva zeBhola. Ngelixa ezi ntlobo zimbini zeValve zisebenzele iinjongo ezifanayo, zinomahluko ophambili ozenza zilungele iimeko ezithile.
Omnye womahluko ophambili phakathi kweevalve zebhabhathane kunye neevalves zebhola kukoyilwa kwayo. Ivalve yebhabhathane, njengoko igama libonisa, line-disc ejikeleza kumbhobho wokulawula ukuhamba. I-disc iqhotyoshelwe kwintonga yensimbi (ebizwa ngokuba sisiqu) esiguqulwe sisifo sesandla okanye isenzo. I-valve yebhola, kwelinye icala, sebenzisa ibhola ye-slerical ngomngxunya kwiziko lokulawula ukuhamba. Ibhola inesiphatho okanye i-lever enokujikelezwa ukuba ivule okanye ivale ivalve.
Obunye umahluko obonakalayo yindlela yokutywina. Kwivalve yebhabhathane, i-disc itywina kwitywina lerabha (ebizwa ngokuba sisihlalo) esibekwe ngaphakathi kwi-valve. Le uyilo luvumela ukusebenza ngokukhawuleza nokulula. Endaweni yoko, ivala yebhola isebenzisa imigangatho emibini etywine, idla okwenziwa nge-teflon, ukubonelela ngetywina eliqinileyo xa ivaliwe. Olu hlengahlengiso luphucula ukusebenza kwe-valve, lwenze ukuba ilungele ukusetyenziswa kwesicelo esifuna ukuvala okuqinileyo.
Xa kufikwa kulawulo lokuhamba, zombini iibhabhathane kunye ne-valve zebhola zibonelela ngomsebenzi obalaseleyo. Nangona kunjalo, i-valves yebhabhathane yaziwa ngokuba nehla ephantsi loxinzelelo xa kuthelekiswa neeValves. Oku kuthetha ukuba amandla amancinci kuyafuneka ukutyhala amanzi okanye ezinye iiarhente zokucinezelwa komlilo ngevalve yebhabhathane, ukunciphisa iindleko zokumpompa. I-valve zebhola, kwelinye icala, zinike ukuvulwa okugcweleyo, zivumela ukuphulukana okungapheliyo kunye nokulahleka okungaphantsi komhlaba, okubenza balungele izicelo eziphezulu zokuhamba.
Ngokweendleko, i-valves zebhabhathane zihlala zinendleko ngakumbi kune-valve yebhola. I-Butterfly Valves'Uyilo olulula kunye nokukhululeka komsebenzi kunegalelo kukufikeleleka kwabo. Ukongeza, ngenxa yetywina lerabha, ivalve yebhabhathane iphantsi kokuvuza, ngaloo ndlela kuncitshiswa iindleko zesondlo.
Kwisishwankathelo, ngelixa zombini iivalves zebhabhathane kunye neeValves zilungele izicelo zokuKhusela umlilo, umahluko wabo ophambili wenza ukuba balungele iimeko ezithile. Cinga ngeemfuno ezithile zenkqubo yokukhusela umlilo kwaye uqwalasele ingcali ukumisela ukuba yeyiphi i-valve (ibhabhathane okanye i-valve yebhotile) yeyona nto iphambili kwiimfuno zakho.
