Ivalve yebhabhathane elawulwa ngokucothayo elawulwa ngokucothayo sisixhobo solawulo lwemibhobho ephucukileyo ekhaya naphesheya. Ifakwe ikakhulu kwindawo yokungenisa i-iturbine yesikhululo sombane wamanzi kwaye isetyenziswe njengevalve yeinjini yomoya; Okanye ifakwe kwindawo yokugcina amanzi, amandla ombane, unikezelo lwamanzi kunye ne-drainage pump outlet, endaweni yevalve yokukhangela kunye nevalve yesango. Xa isebenza, ivalve isebenzisana nenjini ephambili yombhobho, ngokomgaqo wenkqubo yotshintsho lwehydraulic, kwaye ngenkqubo yokuvula nokuvalwa kwangaphambili, inokuqonda ukunqunyulwa kombhobho okuthembekileyo, kushenxise ngokupheleleyo isando samanzi ngaphakathi. umbhobho, kwaye udlale indima ekukhuseleni ukhuseleko lwenkqubo yemibhobho.

Umgaqo wokusebenza

Amandla agciniweyo okuvala ehamile enzima yokulawula ukuvala ukucotha ivalufa yebhabhathane yihamile enzima enokuba namandla, eyahlulahlulwe yayisando esinzima soxinzelelo oluzenzekelayo olugcina ulawulo lwehydraulic olucothayo lokuvala itshekhi ivalve yebhabhathane (emva koku kubhekiselwa kuyo njengoxinzelelo lwehamile enzima yokugcina uhlobo) kunye nokutshixa ubunzima. ihamile yoxinzelelo oluzenzekelayo igcina ulawulo lwehydraulic ukuvala okucothayo hlola ivalve yebhabhathane (emva koku kubhekiselwa kuyo njengohlobo lokutshixa ihamile enzima). Iimeko zenkonzo ikakhulu ziquka imeko yempompo ye-centrifugal, imeko yempompo ye-axial kunye nemeko ye-injini yomoya.

Imeko yokusebenza yempompo ye-centrifugal ene-valve yokuvula (kubandakanywa nepompo edibeneyo ye-centrifugal): qalisa impompo kuqala, kwaye uvule i-valve emva kokulibazisa ixesha elicwangcisiweyo.

Imeko yokusebenza ye-valve evulekileyo yepompo ye-axial flow pump (kubandakanywa ne-axial exutywe nempompo yokuhamba): vula i-valve yempompo ngexesha elifanayo, okanye uvule i-valve kwi-angle ethile kuqala, uze uqale impompo.

Imeko yokusebenza ye turbine yokuvula ivalve: qala uvule ivalve yokudlula ukulinganisa uxinzelelo, emva koko uvule ivalve, emva koko uvule i-injini yomoya.

Ngokuqhelekileyo kuyadingeka ukuvala i-valve ngexesha elifanayo lokuvala okanye ukuhluleka kwamandla phantsi kweemeko ezahlukeneyo zokusebenza.

Umgaqo osisiseko wokusebenza we-electro-hydraulic umi ngolu hlobo lulandelayo:

Xa uvula ivalve, ivalve yesolenoid ibuyela umva, impompo yeoli iyaqala, kwaye ioyile ye-hydraulic ingena kwi-cylinder yeoli ngevalve yokulawula ukuhamba kunye nehose yoxinzelelo oluphezulu ukutyhala ipiston kwaye uqhube i-lever edibeneyo nayo ukuphakamisa isando esinzima ukuya. vula ivalve. Emva kokuba i-valve ivuliwe endaweni, inkqubo yokugcina uxinzelelo oluzenzekelayo iqala; I-motor iyaqhubeka ihlawulisa i-accumulator. Xa uxinzelelo lufikelela kwindawo yokumisela uxinzelelo oluphezulu, ipompo yeoli iyayeka. Ixesha lokuvula i-valve liyakwazi ukulungiswa ngokujikeleza i-handwheel ye-valve yokulawula ukuhamba, kwaye uluhlu lohlengahlengiso luyi-10 ~ 90 imizuzwana.

Xa inkqubo ivuza kwaye uxinzelelo lwehla ukuya kwindawo yokubeka uxinzelelo oluphantsi, i-oyile yepompo yemoto iqala ngokuzenzekelayo kwaye iyeke emva kokufikelela kwindawo yoxinzelelo oluphezulu.

Xa uvala i-valve, i-valve ye-solenoid ibuyela umva, i-oyile yoxinzelelo kwi-cylinder yeoli ibuyela kwitanki yeoli ngokusebenzisa i-valve edibeneyo ehamba ngokukhawuleza kwaye ecothayo, i-hose ephezulu yoxinzelelo kunye ne-solenoid valve, isando esinzima siwela phantsi, kwaye intonga yokudibanisa iqhuba. i-butterfly plate ukujikeleza ukuvala i-valve, ukwenzela ukuba unqumle ngokukhawuleza ukuhamba kwamanzi amaninzi malunga ne-70% ye-stroke yangaphambili; I-30% yokugqibela ye-stroke ivalwe kancinci. I-engile yokuvala ngokukhawuleza kunye nokucotha kunye nexesha le-buffer yenqanaba ngalinye linokulungelelaniswa ngokweemeko ezichanekileyo zokusebenza zombhobho ukuphelisa ngokufanelekileyo ihamile yamanzi kumbhobho; Ixesha lohlengahlengiso liyi-2 imizuzwana ukuya kwi-25 imizuzwana yokuvala ngokukhawuleza kunye nemizuzwana ye-6 ukuya kwi-90 imizuzwana yokuvala ngokukhawuleza.

Kwinkqubo yokuvula nokuvala, i-valve inokumiswa kuyo nayiphi na indawo ephakathi ngeqhosha lokumisa. Isenzo sokumisa sisetyenziswa ikakhulu ukulungisa inkqubo.

Impompo eyenziwe ngesandla isetyenziswa ikakhulu ukulungisa ingxaki. Xa kungekho mbane okanye ipompo yeoli ayikwazi ukusebenza ngokuqhelekileyo, ukugungqa ipompo yesandla kunokugqiba ukuvulwa kwevalve kunye nokugcinwa koxinzelelo lwenkqubo. Vula ivalve yokumisa eqhele ukuvaleka, phantsi kwentshukumo yamandla anokubakho ngehamile kunye netorque ye-hydrodynamic, intonga yokudibanisa iqhuba ipleyiti yebhabhathane ukuze ijikelezise ukuvala ivalve.
