Sephahla se laolanghistori ea tsoelo-pele e laolang lintlha tsa ho kenya li-valve kenyelletso e khutšoanyane
1. Tsoelo-pele ea li-valve tse laolang li amana haufi-ufi le nts'etsopele ea mekhoa ea tlhahiso ea indasteri.
Mehleng ea boholo-holo, e le ho laola ho phalla ha metsi linōkeng kapa linōkeng, batho ba ne ba sebelisa majoe a maholo kapa likutu tsa lifate ho thibela ho phalla ha metsi kapa ho fetola tsela eo metsi a phallang ka eona.
Tsoelopele ea Baegepeta le Bagerike e ile ea qapa mefuta e mengata ea li-valve tsa khale, tse sebelisetsoang ho nosetsa lijalo, har'a lintho tse ling.
Leha ho le joalo, hoa lumeloa ka kakaretso hore Baroma ba boholo-holo ba ile ba qapa mokhoa o rarahaneng oa metsi bakeng sa ho nosetsa lijalo, o nang le li-valve tsa plug le plunger le tšebeliso ea li-check valves ho thibela ho phalla ha metsi khahlano le ka morao.
Nakong ea Renaissance, baetsi ba litšoantšo le baqapi. LeonardodaVinc e entse li-valve bakeng sa liforo, merero ea ho nosetsa le lisebelisoa tse ling tse kholo tsa hydraulic, 'me tse ngata tsa tharollo ea hae ea tekheniki li ntse li le teng le kajeno.
Nalane ea sejoale-joale ea indasteri ea li-valve e tsamaellana le indasteri. Ka tsoelo-pele ea indasteri, ThomasNewcomen o ile a qapa mochine oa mouoane oa indasteri ka deske e ka pele ka 1705, e hlokang taolo ea ts'ebetso ea mochine oa mouoane. JamesWatt o ile a qapa molaoli oa ho lokisa lebelo ka deskeng e ka pele. Batho ba ntseng ba eketseha ba ela hloko taolo ea phallo ea mokelikeli.
Molaoli oa khale ka ho fetisisa e ne e le molaoli oa pompo o entsoeng ke WilliamFisher ka 1880. E ne e le molaoli ea ikemetseng ea nang le hamore e boima. Ha khatello e ka morao ea valve e eketseha, ho buloa ha molaoli ho ile ha fokotseha tlas'a ketso ea hamore e boima, e le ho finyella phello ea taolo ea khatello e tsitsitseng.

Eccentric rotary valve e na le tiiso e ntle, matla a phallo e kholo, e ka sebelisoa liketsahalong tse kholo tsa phapang ea khatello.
Ho tloha qalong ea lilemo tsa bo-80, ho ile ha tsoaloa mefuta e fapaneng ea li-valve tse nyenyane tse laolang, tse etsang hore boima le bophahamo ba li-valve tse laolang li theohe 'me matla a phallo a ntlafatse.
Ho tloha qalong ea lilemo tsa bo-1990, ka ts'ebeliso e pharaletseng ea lisebelisoa tsa taolo ea likhomphutha, litlhoko tsa li-valve tse laolang tse bohlale li ntse li eketseha, 'me li hlahile mefuta e fapaneng ea li-valve tsa motlakase tse bohlale le li-valve tsa masimong tse laolang li-valve tse nang le boemo ba li-valve tse bohlale.
Qalong ea lekholo la 2l, valve e laolang fieldbus e 'nile ea sebelisoa, ka ho theoha ha mosebetsi oa taolo, tlhokahalo ea valve e laolang e ntse e phahama le ho feta.
Nts'etsopele ea li-valve tse laolang le taolo ea ts'ebetso ea indasteri e etsoa ka mokhoa o ts'oanang.
E le ho ntlafatsa boleng ba taolo ea tsamaiso ea taolo, litlhoko tse phahameng li behoa pele bakeng sa karolo ka 'ngoe ea tsamaiso ea taolo.
Ka mohlala, likarolo tsa ho lemoha le li-transmitter li hloka ho lemoha ho phahameng le ho nepahala ha phetisetso, karabo e potlakileng le botsitso bo phahameng ba data; Molaoli le li-actuator tse ling li hloka libaka tse nyane tse shoeleng le khohlano, ho ipheta ho betere le nako e khuts'oane ea karabo, 'me e ka fana ka matšeliso bakeng sa litšobotsi tsa phallo e sa tsitsang ea ntho.
Ka nako e ts'oanang, ka lebaka la ts'ebetso e kholo le e ntle ea tlhahiso ea indasteri, molaoli joalo-joalo le tsona li beha litlhoko tse phahameng.
Lintlha tse ka sehloohong tsa ho lokisa li-valve li hlahisoa ka bokhutšoanyane
Ke mekhoa efe e nepahetseng ea ho kenya bakeng sa ho lokisa lintlha tsa ho kenya li-valve, tse ka ntlafatsang katleho ea valve le ho fokotsa ho roala ha li-valve? Lintlha tse latelang ke kenyelletso ea lintlha tse kholo tsa ho lokisa ho kenya li-valve bakeng sa referense ea hau. 1) Boemo ba ho kenya, bophahamo, tataiso ea ho kena le ea ho tsoa e tlameha ho finyella litlhoko tsa moralo, 'me khokahano e lokela ho ba e tiileng le e tiileng. 2) Motsoako oa mefuta eohle ea li-valve tsa letsoho tse kentsoeng pompong ea ho kenella ka mocheso o ke ke oa theohela tlase. 3) Valve e tlameha ho hlahlojoa pele e kenngoa.
