Ivalvu yebhabhathane elawulwa yiHydraulic controlled slow closing check butterfly sisixhobo sokulawula imibhobho esiphucukileyo ekhaya nakwamanye amazwe. Ifakwe ikakhulu kwindawo yokungena kweturbine yesitishi samandla e-hydropower kwaye isetyenziswa njengevalvu yokungena kweturbine; Okanye ifakwe kwindawo yokugcina amanzi, umbane, unikezelo lwamanzi kunye nendawo yokuphuma kwepompo yokukhupha amanzi, endaweni yevalvu yokujonga kunye nevalvu yesango. Xa isebenza, ivalvu isebenzisana nenjini ephambili yombhobho, ngokwemigaqo yenkqubo yokutshintsha kwe-hydraulic, kwaye ngokusebenzisa iinkqubo zokuvula nokuvala ezicwangcisiweyo, inokufezekisa ukunqunyulwa okuthembekileyo kombhobho, isuse ngempumelelo isando samanzi kumbhobho, kwaye idlale indima ekukhuseleni ukhuseleko lwenkqubo yombhobho.

Umgaqo wokusebenza

Amandla okuvala agciniweyo e-hammer heavy hammer control hydraulic slow closing check butterfly valve yi-heavy hammer potential energy, eyahlulwe yaba yi-heavy hammer automatic pressure maintaining hydraulic control slow closing check butterfly valve (eza kubizwa ngokuba yi-heavy hammer pressure maintaining type) kunye ne-locking heavy hammer pressure automatic maintaining hydraulic control slow closing check butterfly valve (eza kubizwa ngokuba yi-heavy hammer locking type). Iimeko zenkonzo ziquka imeko ye-centrifugal pump, imeko ye-axial flow pump kunye nemeko ye-turbine.

Imeko yokusebenza kwepompo ye-centrifugal enokuvulwa kwevalvu (kuquka nepompo ye-centrifugal mixed flow): qala ipompo kuqala, uze uvule ivalvu emva kokulibazisa ixesha elicwangcisiweyo.

Imeko yokusebenza yepompo ye-axial flow yevalvu evulekileyo (kubandakanya ipompo ye-axial mixed flow): vula ivalvu yepompo ngaxeshanye, okanye uvule ivalvu kwi-engile ethile kuqala, uze uqalise ipompo.

Imeko yokusebenza kwe-valve opening turbine: qala uvule i-bypass valve ukuze ulinganisele uxinzelelo, emva koko uvule i-valve, uze uvule i-turbine.

Ngokwesiqhelo kufuneka uvale ivalvu ngexesha elinye lokucima okanye ukucima kombane phantsi kweemeko ezahlukeneyo zokusebenza.

Umgaqo osisiseko wokusebenza kwe-electro-hydraulic ngolu hlobo lulandelayo:

Xa ivula ivalvu, ivalvu yesolenoid iyajika, ipompo yeoyile iyaqala, kwaye ioyile yehydraulic ingena kwisilinda yeoyile ngevalvu yokulawula ukuhamba kunye nepayipi yoxinzelelo oluphezulu ukuze ityhale ipiston kwaye iqhube i-lever edibene nayo ukuze iphakamise isando esinzima ukuvula ivalvu. Emva kokuba ivalvu ivuliwe endaweni yayo, inkqubo yokugcina uxinzelelo oluzenzekelayo iyaqala; Imoto iyaqhubeka nokutshaja i-accumulator. Xa uxinzelelo lufikelela kwinqanaba elimiselweyo loxinzelelo oluphezulu, ipompo yeoyile iyayeka. Ixesha lokuvula ivalvu linokulungiswa ngokujikeleza ivili lesandla levalvu yokulawula ukuhamba, kwaye uluhlu lohlengahlengiso yimizuzwana eli-10 ukuya kwengama-90.

Xa inkqubo ivuza kwaye uxinzelelo lwehla luye kwinqanaba elisezantsi loxinzelelo, i-oyile pump motor iqala ngokuzenzekelayo ize ime emva kokufikelela kwinqanaba eliphezulu loxinzelelo.

Xa ivala ivalvu, ivalvu yesolenoid iyajika, ioyile yoxinzelelo kwi-oyile cylinder ibuyela kwitanki yeoyile ngevalvu yokuhamba ngokukhawuleza nangokucothayo kwamalungu, ipayipi yoxinzelelo oluphezulu kunye nevalvu yesolenoid, isando esinzima siyawa, kwaye intonga yokudibanisa iqhuba ipleyiti yebhabhathane ukuba ijikeleze ukuze ivale ivalvu, ukuze inqumle ngokukhawuleza ukuhamba kwamanzi malunga ne-70% yestroke yangaphambili; I-30% yokugqibela yestroke ivalwa kancinci. I-engile yokuvala ngokukhawuleza nangokucothayo kunye nexesha le-buffer lesigaba ngasinye linokulungiswa ngokweemeko zokusebenza zombhobho ukuze kususwe ngempumelelo isando samanzi kumbhobho; Ixesha lokulungisa liyimizuzwana emi-2 ukuya kwimizuzwana engama-25 yokuvala ngokukhawuleza kunye nemizuzwana emi-6 ukuya kwimizuzwana engama-90 yokuvala kancinci.

Kwinkqubo yokuvula nokuvala, ivalvu inokuma nakweyiphi na indawo ephakathi ngeqhosha lokumisa. Isenzo sokumisa sisetyenziselwa ikakhulu ukulungisa ingxaki kwinkqubo.

Ipompo yesandla isetyenziselwa kakhulu ukulungisa iingxaki kwinkqubo. Xa kungekho mbane okanye ipompo yeoyile ingasebenzi kakuhle, ukushukumisa ipompo yesandla kunokugqiba ukuvulwa kwevalvu kunye nokugcinwa koxinzelelo kwenkqubo. Vula ivalvu yokumisa evalekileyo, phantsi kwesenzo se-hammer potential energy kunye ne-hydrodynamic torque, intonga yokudibanisa iqhuba ipleyiti yebhabhathane ukuba ijikeleze ukuze ivale ivalvu.
