I-valve yokulawulaumlando wokuthuthuka olawula amaphuzu wokufakwa kwama-valvu isingeniso esifushane
1. Ukuthuthukiswa kwama-valve okulawula kuhlobene eduze nokuthuthukiswa kwezinqubo zokukhiqiza zezimboni.
Ezikhathini zasendulo, ukuze kulawuleke ukugeleza kwamanzi emifuleni noma emifudlaneni, abantu babesebenzisa amatshe amakhulu noma iziqu zezihlahla ukuze bamise ukugeleza kwamanzi noma bashintshe indlela amanzi ageleza ngayo.
Impucuko yaseGibhithe neyamaGreki yasungula izinhlobo ezimbalwa zamavalvu zasendulo, ezisetshenziselwa ukuchelela izitshalo, phakathi kwezinye izinto.
Kodwa-ke, kuyavunywa ukuthi amaRoma asendulo asungula uhlelo lwamanzi oluyinkimbinkimbi lokunisela izitshalo, olunama-plug nama-plunger valves kanye nokusetshenziswa kwamavalvu okuhlola ukuvimbela ukugeleza kwamanzi ngokumelene ne-reverse.
Ngesikhathi seRenaissance, abaculi nabaqambi. I-LeonardodaVinc yakha ama-valve emisele, amaphrojekthi okunisela nezinye izinhlelo ezinkulu ze-hydraulic, futhi eziningi zezixazululo zakhe zobuchwepheshe zisekhona nanamuhla.
Umlando wesimanje wemboni yamavalvu uhambisane nezimboni. Ngokuthuthuka kwemboni, uThomasNewcomen wasungula injini ye-steam yezimboni ngedeski elingaphambili ngo-1705, edinga ukulawula ukusebenza kwenjini ye-steam. UJamesWatt usungule isilawuli sokulungisa isivinini ngedeski elingaphambili. Abantu abaningi ngokwengeziwe bayanaka ukulawulwa kokugeleza koketshezi.
Isilawuli sakuqala sasiyisilawuli sephampu esenziwe nguWilliamFisher ngo-1880. Kwakuyisilawuli esizimelayo esinesando esindayo. Lapho ukucindezela ngemuva kwe-valve kwanda, ukuvulwa komlawuli kwancishiswa ngaphansi kwesenzo sesando esindayo, ukuze kuzuzwe umphumela wokulawula ukucindezela okuzinzile.
Ngekhulu lama-20 kuya ku-1930s, ukwakheka komzimba we-valve olawulayo wevalvu eyindilinga eyindilinga (b>

Ngama-70's valvu elawula imikhono isetshenziswa kabanzi ekulawuleni inqubo yokukhiqiza ezimbonini, ivalvu ejikelezayo e-eccentric eyakhiwe i-eccentricplugv>
I-Eccentric rotary valve inokubekwa uphawu okuhle, umthamo omkhulu wokugeleza, ingasetshenziswa ezikhathini ezinkulu zokuhlukanisa ingcindezi.
Kusukela ekuqaleni kweminyaka yama-80's, i-valve ehlukahlukene emihle yokulawula yazalwa, okwenza isisindo nokuphakama kwe-valve elawulayo yehle futhi umthamo wokugeleza uthuthuke.
Kusukela ekuqaleni kwawo-1990s, ngokusetshenziswa okubanzi kwemishini yokulawula amakhompiyutha, izidingo zamavalvu alawulayo ahlakaniphile ziya ngokuya ziba namandla kakhulu, futhi sezizelwe izinhlobo ezihlukahlukene zamavalvu kagesi ahlakaniphile namavalvu alawula amabhasi asensimini ane-valve positioner ehlakaniphile.
Ekuqaleni kwekhulu le-2l, i-valve elawula i-fieldbus isetshenzisiwe, ngokunyakaza okuya phansi komsebenzi wokulawula, imfuneko ye-valve yokulawula iya ngokuya iphakama.
Ukuthuthukiswa kwe-valve yokulawula kanye nokulawulwa kwenqubo yezimboni kwenziwa ngokuvumelana.
Ukuze kuthuthukiswe ikhwalithi yokulawula yesistimu yokulawula, izidingo eziphakeme zibekwe phambili engxenyeni ngayinye yesistimu yokulawula.
Isibonelo, izakhi zokuthola kanye nezidluliseli zidinga ukutholwa okuphezulu nokunemba kokudlulisela, ukuphendula okusheshayo kanye nokuzinza okuphezulu kwedatha; Isilawuli namanye ama-actuator adinga indawo encane efile kanye nokungqubuzana, ukuphindaphinda okungcono kanye nesikhathi esifushane sokuphendula, futhi anganikeza isinxephezelo sezimpawu zokugeleza okungaqondile kwento.
Ngesikhathi esifanayo, ngenxa yenqubo yokukhiqiza yezimboni ezinkulu nezinhle, umlawuli nokunye babeka phambili izidingo eziphakeme.
Amaphuzu ayinhloko okufakwa kwe-valve yokulungisa ethulwa kafushane
Iziphi izindlela ezilungile zokufaka zokulungisa amaphuzu okufaka ama-valve, ezingathuthukisa ukusebenza kahle kwe-valve nokunciphisa ukuguga kwe-valve? Okulandelayo ukwethulwa kwamaphuzu asemqoka okulungisa ukufakwa kwamavalvu ukuze uthole inkomba yakho. I-1) Indawo yokufaka, ukuphakama, indawo yokungena kanye nesiqondiso sokuphuma kufanele sihlangabezane nezidingo zokuklama, futhi uxhumano kufanele luqine futhi luqine. 2) Isibambo sazo zonke izinhlobo zamavalvu okwenziwa ngesandla afakwe epayipini lokufakwa kwe-thermal akumele siye phansi. 3) I-valve kufanele ihlolwe ngaphambi kokufakwa. I-nameplate yevalvu kufanele ihambisane nezinga likazwelonke lamanje elithi “Universal Valve Mark” GB 12220. Kuvalvu umfutho wayo wokusebenza ungaphezu kuka-1.0MPa futhi idlala indima yokusika epayipini eliyinhloko, ukuhlolwa kwamandla nokusebenza okuqinile kufanele kwenziwe. ngaphandle ngaphambi kokufakwa, futhi i-valve efanelekayo ingasetshenziswa. Ukuhlolwa kwamandla, ingcindezi yokuhlola izikhathi eziyi-1.5 ukucindezela okuzisholo, ubude besikhathi abukho ngaphansi kuka-5min, igobolondo le-valve, ukupakisha kufanele kuqeqeshwe ngaphandle kokuvuza. Ukuhlolwa kokuqina, ingcindezi yokuhlola izikhathi eziyi-1.1 zokucindezela okuzisholo; Ingcindezi yokuhlolwa ngesikhathi sokuhlolwa kufanele ihlangabezane nezidingo ze-GB 50243 ejwayelekile, endaweni yokuvala idiski akukho ukuvuza njengokufanelekile.
