Bohlokoa ba li-valve moralong oa lipeipi.
Litsamaisong tsa liphaephe tsa mokelikeli, li-valve ke likarolo tsa taolo tseo karolo ea tsona e ka sehloohong e leng ho arola lisebelisoa le lisebelisoa tsa liphaephe, ho laola phallo, ho thibela ho khutla, ho laola le ho ntša khatello. Hobane tsamaiso ea liphaephe ho khetha valve e loketseng ka ho fetisisa e bohlokoa haholo, ka hona, ho utloisisa litšobotsi tsa valve le khetho ea mehato ea li-valve le motheo le tsona li fetoha tsa bohlokoa.
Bohlokoa ba li-valve moralong oa liphaephe
1. Litšobotsi tsa li-valve ka kakaretso ke tsa mefuta e 'meli, litšoaneleho tsa tšebeletso le litšobotsi tsa sebopeho.
Litšobotsi tsa tšebeliso: e etsa qeto ea hore na ts'ebeliso e ka sehloohong ea ts'ebetso ea li-valve le mefuta e mengata ea ts'ebeliso, ke ea litšobotsi tsa tšebeliso ea li-valve ke: sehlopha sa li-valve (valve ea potoloho e koetsoeng, valve e laolang, valve ea polokeho, joalo-joalo); Mofuta oa sehlahisoa (valve ea heke, valve ea globe, valve ea serurubele, valve ea bolo, joalo-joalo); Likarolo tse ka sehloohong tsa valve ('mele oa valve, sekoahelo, stem, disc, sealing surface) lintho tse bonahalang; Mokhoa oa phetisetso ea li-valve, joalo-joalo Litšobotsi tsa tlhophiso: e etsa qeto ea ho kenya belofo, ho lokisa, ho lokisa le mekhoa e meng ea litšobotsi tse ling tsa sebopeho, e leng karolo ea litšobotsi tsa sebopeho: bolelele ba tlhophiso ea belofo le bophahamo ba kakaretso, le khokahano ea phala. foromo (khokahanyo ea flange, khokahanyo ea khoele, khokahanyo ea hoop, khokahanyo ea khoele ea ka ntle, khokahanyo ea ho qetela ea welding, joalo-joalo); Sebopeho sa ho tiisa bokaholimo (kenya selikalikoe, selikalikoe sa khoele, sefahleho, ho cheselletsa ho fafatsa, 'mele oa' mele); Sebopeho sa sebopeho sa li-valve (thupa e potolohang, molamu oa ho phahamisa), joalo-joalo.
2. Mehato le motheo oa khetho ea valve ke tse latelang:
⑴ Mehato ea khetho
Hlakola valve ka lisebelisoa kapa lisebelisoa tsa lisebelisoa, fumana maemo a sebetsang a valve: sebaka se sebetsang, khatello ea ho sebetsa, mocheso o sebetsang joalo-joalo.
(2) Etsa qeto ea boholo ba lebitso le mokhoa oa ho hokahanya ha phala e kopanyang le valve: flange, khoele, welding, joalo-joalo.
(3) Etsa qeto ea mokhoa oa ho sebelisa valve: manual, motlakase, electromagnetic, pneumatic kapa hydraulic, khokahano ea motlakase kapa electro-hydraulic linkage.
④ Ho latela mokhoa oa phetisetso ea liphaephe, khatello ea ho sebetsa, mocheso o sebetsang ho fumana hore na khetla ea valve e khethiloeng le likarolo tse ka hare tsa thepa: tšepe e bohlooho, tšepe e ka tšeptjoang, tšepe ea ductile, tšepe ea carbon, tšepe ea alloy, tšepe e sa keneleng acid, koporo. motsoako, joalo-joalo.
⑤ Khetha mofuta oa valve: valve e koetsoeng, valve e laolang, valve ea tšireletso, joalo-joalo.
⑥ Fumana mofuta oa valve: valve ea heke, valve ea lefats'e, valve ea bolo, valve ea serurubele, valve ea throttle, valve ea polokeho, valve e fokotsang khatello, sefi sa mouoane, joalo-joalo.
Etsa qeto ea litekanyo tsa valve: bakeng sa valve ea othomathike, ho latela litlhoko tse fapaneng ho fumana hore na ho hanyetsa ho phalla, matla a ho ntša metsi, khatello ea morao, ebe o fumana bophara ba "phaephe" le bophara ba lesoba la setulo.
⑧ ho tseba likarolo tse khethiloeng tsa geometri tsa valve: bolelele ba sebopeho, sebopeho sa khokahanyo ea flange le boholo, e bulehileng le ho koala ka mor'a tataiso ea bophahamo ba valve ea boholo, ho hokahanya ha boholo ba lesoba la bolt le palo, boholo ba sebopeho sa valve kaofela.
⑨ Sebelisa lintlha tse fumanehang: lethathamo la lihlahisoa tsa li-valve, mehlala ea lihlahisoa tsa li-valve, joalo-joalo, ho khetha lihlahisoa tse nepahetseng tsa li-valve.
Motheo oa ho khetha valve
(1) tšebeliso ea valve e khethiloeng, maemo a sebetsang le mokhoa oa ho laola.
(2) Sebopeho sa mochine o sebetsang: khatello ea ho sebetsa, mocheso oa ho sebetsa, ts'ebetso ea kutu, ho sa tsotellehe hore na e na le likaroloana tse tiileng, ebang ke chefo, ho sa tsotellehe hore na e ka chesa, ho phatloha ho hoholo, viscosity e bohareng joalo-joalo.
③ Litlhoko tsa litšobotsi tsa mokelikeli oa li-valve: ho hanyetsa ho phalla, matla a ho ntša metsi, litšobotsi tsa phallo, boemo ba ho tiisa joalo-joalo.
(4) Litlhoko tsa boholo ba ho kenya le boholo ba ponahalo: bophara ba lebitso, ho hokahanya le pipe le boholo ba khokahanyo, boholo ba ponahalo kapa moeli oa boima.
⑤ Litlhoko tse eketsehileng bakeng sa ho tšepahala ha lihlahisoa tsa li-valve, bophelo ba tšebeletso le ts'ebetso ea bopaki ba ho phatloha ha lisebelisoa tsa motlakase. Ho ea ka khetho e ka holimo ea motheo oa li-valve le mehato, khetho e utloahalang le e nepahetseng ea valve e tlameha ho ba le kutloisiso e qaqileng ea sebopeho sa ka hare sa mefuta e sa tšoaneng ea li-valve, e le hore u khone ho khetha ka mokhoa o khethehileng valve ho etsa khetho e nepahetseng. Taolo ea ho qetela ea pipeline ke valve. Likarolo tsa ho bula le ho koala li-valve li laola phallo ea mecha ea phatlalatso ka phaephe, sebōpeho sa mocha oa phallo ea valve se nolofalletsa valve ho ba le litšobotsi tse itseng tsa phallo, tse lokelang ho tsotelloa ha ho khethoa valve e loketseng ho kenngoa tsamaisong ea liphaephe.
Lintlha tse latelang ke melao-motheo e lokelang ho lateloa ha u khetha li-valve
(1) Sephahla se nang le sekhahla se khaotsoeng le se bulehileng se phallang ke sephahla se otlolohileng, ho hanyetsa ho phalla ho nyenyane, hangata ho khethoa e le valve e nang le sekhahla se khaotsoeng le se bulehileng. Valofo e koetsoeng ka tlase (valve ea lefats'e, valve ea plunger) ka lebaka la tsela ea eona ea ho phalla, ho hanyetsa ho phalla ho phahame ho feta li-valve tse ling, kahoo ha ho khethoe ka tlase. Li-valve tse koetsoeng li ka sebelisoa moo ho hanyetsanang le phallo e phahameng ho lumelloang.
Hangata valve ea ho laola e bonolo ho fetola ho phalla ha valve e le ho phalla ha taolo. Li-valve tsa ho koala tse eang tlase (joalo ka li-valve tsa GLOBE) LI LOKELANG HO BAKENG SA MORERO ENA HOBANE BOHLOKO BA SETULO BO LEBANE LE STROKE EA SHUTOFF. LI-VALVES tsa Rotary (PLUG, butterfly, BALL valves) le FLEXURE BODY VALVES (PINCH, DIAPHRAGM) LI TSE FUMANEHILE HO TSAMAISA HO TSAMAEA, empa hangata FEELA FEELA ka har'a mefuta e fokolang ea li-valve DIAMETERS.
