E khona ho hlahloba li-valve ho thibela phetoho ea pompo

Sheba li-valvee ka thibela ka katleho phetoho ea pompo. Molao-motheo oa mantlha ke ho itšetleha ka phapano ea khatello ea mokelikeli ho fihlela tsamaiso ea tsela e le 'ngoe le ho khutlisa cutoff. Ha pompo e sebetsa ka mokhoa o tloaelehileng, phallo e tsoelang pele ea mokelikeli e sutumelletsa "valve disc" hore e bulehe, 'me sehare se feta hantle; Ha pompo e emisa ka tšohanyetso kapa khatello ea tsamaiso e sa tloaeleha, e etsa hore mokelikeli o phalle ka morao, "valve disc" e koala ka potlako tlas'a matla a eona a khoheli, matla a selemo kapa khatello ea metsi, e thibelang tsela ea ho phalla ka morao. Tšobotsi ena e etsa hore e be lisebelisoa tsa bohlokoa bakeng sa ho sireletsa lipompo le li-motors tsa ho khanna.

Ho nka mohlala oa tsamaiso ea pompo ea metsi, haeba aho hlahloba valveha e kenyelelitsoe, ha pompo ea metsi e emisa ka lebaka la ho hlōleha ha matla kapa ho se sebetse, khatello e ka hare ho pompo e nyamela, 'me metsi a nang le khatello e phahameng a kopantsoeng le phallo a tla phalla ho khutlela pompong ka tsela e fapaneng, a sutumelletsa impeller ho khutlela morao. Phetoho e khutlisetsang morao ha e bake feela ho theoloa ha sets'oants'o le ho roala ha letsoho la shaft, empa hape e ka lebisa khatellong ea motlakase le ho felloa ke matla, e leng kotsi e kholo ho polokeho ea lisebelisoa. Ka mor'a ho kenya valve ea ho hlahloba, ho phalla ha metsi ka morao ho tla etsa hore hang-hang disk ea valve e koalehe, e khaole mocha oa ho phalla, ka hona ho qoba tšenyo ea 'mele oa pompo ka lebaka la ho potoloha.

The anti reverse effect ofhlahloba li-valvee amana haufi-ufi le mofuta oa tsona le boemo ba ho kenya. Li-valve tsa ho hlahloba li-swing li na le khanyetso e fokolang ea phallo ka lebaka la ho potoloha ha disc valve ho potoloha axis, e leng se etsang hore e tšoanelehe bakeng sa liphaephe tse kholo, tse bohareng le tse tlaase; Phahamisa li-valve tsa ho hlahloba li fihlella ho tiisoa ka ho thellela disc ea valve haufi le axis, ka ts'ebetso e ntle ea ho tiisa. Leha ho le joalo, li na le khanyetso e phahameng ea phallo 'me li sebelisoa haholo maemong a manyane a bophara le khatello e phahameng.

Ho phaella moo, li-valve tsa ho hlahloba li ka boela tsa fokotsa ts'ebetso ea hamore ea metsi - ha disc ea valve e koala ka potlako, le hoja ho ka 'na ha e-ba le khatello e khutšoanyane ea khatello ka lebaka la inertia ea mokelikeli, matla a eona a senyang a ka fokotsoa ka ho khetha mofuta o utloahalang (joaloka li-valve tsa ho hlahloba axial flow) kapa ho kenya lisebelisoa tsa ho thibela metsi. Ka hona, ho kenya valve ea ho hlahloba sebakeng sa pompo hase feela tekanyo e hlokahalang ho thibela ho potoloha ka morao, empa hape ke sehokelo sa bohlokoa ho netefatsa ts'ebetso e sireletsehileng le e tsitsitseng ea tsamaiso eohle ea mokelikeli.
