Iivalve yokukhupha umoyasisixhobo esifunekayo sokususwa ngokukhawuleza kwegesi kumbhobho, esetyenziselwa ukuphucula ukusebenza kakuhle kwezixhobo zokuhambisa amanzi kunye nokukhusela umbhobho kwi-deformation kunye nokuphuka.Ifakwe kwi-outlet ye-pump port okanye kumgca wokunikezelwa kwamanzi kunye nokusabalalisa ukuhanjiswa kwamanzi ukuze kususwe umthamo omkhulu womoya ovela kumbhobho ukuphucula ukusebenza kakuhle kombhobho kunye nepompo.Kwimeko yoxinzelelo olubi kumbhobho, i-valve inokufunxa ngokukhawuleza emoyeni ukukhusela umonakalo obangelwa uxinzelelo olubi.
Xa impompo yamanzi iyeka ukusebenza, uxinzelelo olubi luya kuveliswa nangaliphi na ixesha.I-float iyawa nangaliphi na ixesha.Kwimeko yokukhupha, i-buoy idonsa enye isiphelo se-lever ngenxa yesenzo sobunzima.Ngeli xesha, i-lever ikwimeko ethambekele, kwaye kukho i-gap kwi-contact part of the lever kunye ne-exhaust hole.
Umoya ukhutshwa ngumngxuma wokuphuma kwesi sikhewu.Ngokuphuma komoya, inqanaba lamanzi liyanyuka kwaye i-buoy idada phezulu phantsi kwe-buoyancy yamanzi.Ubuso besiphelo sokutywina kwi-lever ngokuthe ngcembe ucinezela umngxuma ongaphezulu we-vent de umngxuma wonke we-vent uvalwe ngokupheleleyo kunye nevalve yokukhupha umoya ivalwe ngokupheleleyo.
Imiqathango yokuseta ivalve yokukhupha umoya:
1.I-valve yokukhupha umoya kufuneka ifakwe ngokuthe nkqo, oko kukuthi, kufuneka iqinisekise ukuba i-buoy yangaphakathi ikwimeko ethe nkqo, ukuze ingachaphazeli ukukhupha.
2.Xa iivalve yokukhupha umoyaifakwe, kungcono ukuyifaka kunye nevalve yokwahlula, ukuze xa iivalve yokukhupha umoyaidinga ukususwa ukuze igcinwe, inokuqinisekisa ukutywinwa kwenkqubo kwaye amanzi awaphumi.
3.Iivalve yokukhupha umoyaifakwe ngokubanzi kwindawo ephezulu yenkqubo, enceda ekuphuculeni ukusebenza kakuhle kokukhupha.
Umsebenzi weivalve yokukhupha umoyaikakhulu kukususa umoya ngaphakathi kumbhobho.Ngenxa yokuba ngokuqhelekileyo kukho umlinganiselo othile womoya onyibilikisiweyo emanzini, kwaye ukunyibilika komoya kuncipha ngokunyuka kwamaqondo obushushu, ngoko ke kwinkqubo yokujikeleza kwamanzi igesi yahlukana ngokuthe ngcembe emanzini, kwaye ngokuthe ngcembe iqokelelwa ndawonye ukuze yenze amaqamza amakhulu okanye igesi. ikholamu, ngenxa yokongezwa kwamanzi, ngoko kukho rhoqo ukuveliswa kwegesi.
Isetyenziswa ngokubanzi kwinkqubo yokufudumeza ezimeleyo, inkqubo yokufudumeza esembindini, ibhoyila yokufudumeza, umoya womoya ophakathi, ukufudumeza umgangatho kunye nenkqubo yokufudumala yelanga kunye nokunye ukukhupha imibhobho.
Iimfuno zokusebenza kwevalve yokukhupha umoya:
1.Iivalve yokukhupha umoyakufuneka ibe nomthamo omkhulu wokukhupha, kwaye xa umbhobho ongenanto wombhobho uzaliswe ngamanzi, unokuqonda ukukhupha ngokukhawuleza kwaye ubuyisele kumthamo oqhelekileyo wonikezelo lwamanzi ngexesha elifutshane kakhulu.
2.Xa iivalve yokukhupha umoyainoxinzelelo olubi kumbhobho, i-piston kufuneka ikwazi ukuvula ngokukhawuleza kwaye ifake inani elikhulu lomoya wangaphandle ngokukhawuleza ukuqinisekisa ukuba umbhobho awuyi konakala ngoxinzelelo olubi.Kwaye phantsi koxinzelelo lokusebenza, umkhondo womoya oqokelelwe kumbhobho ungakhutshwa.
3.Iivalve yokukhupha umoyakufuneka ibenoxinzelelo oluphezulu lokuvala umoya.Ngexesha elifutshane ngaphambi kokuba i-piston ivalwe, kufuneka ibe nomthamo owaneleyo wokukhupha umoya kwipayipi kunye nokuphucula ukusebenza kakuhle kokunikezelwa kwamanzi.
4.Uxinzelelo lokuvala amanzi lweivalve yokukhupha umoyaakufanele ibe ngaphezu kwe-0.02 MPa, kunye neivalve yokukhupha umoyainokuvalwa phantsi koxinzelelo lwamanzi aphantsi ukuphepha umthamo omkhulu wokukhupha amanzi.
5.Ivalve yokukhupha umoyakufuneka yenziwe ngebhola edadayo yentsimbi engatyiwa (ibhakethi edadayo) njengendawo yokuvula kunye nokuvala.
6.Umzimba wevalve yokukhutshwa komoya kufuneka uxhotyiswe nge-cylinder yangaphakathi yokukhusela i-anti-impact ukukhusela umonakalo wangaphambi kwexesha webhola edadayo (ibhakethi edadayo) obangelwa yimpembelelo ethe ngqo yokuhamba kwamanzi ngesantya esiphezulu kwibhola edadayo (ibhakethi edadayo) emva kokutya okuninzi.
7.Ye-DN≥100ivalve yokukhupha umoya, ulwahlulo lwesakhiwo luyamkelwa, oluqulunqwe inani elikhuluivalve yokukhupha umoyakwayeivalve yokukhupha umoya ngokuzenzekelayoukuhlangabezana neemfuno zoxinzelelo lwemibhobho.Iivalve yokukhupha umoya ngokuzenzekelayokufuneka isebenzise indlela ye-lever ephindwe kabini yokwandisa kakhulu i-buoyancy yebhola edadayo, kwaye inqanaba lamanzi lokuvala liphantsi.Ukungcola emanzini akulula ukuqhagamshelana nomgangatho wokutywinwa, kwaye i-port yokukhupha ayiyi kuvinjelwa, kwaye ukusebenza kwayo okuchasayo kunokuphuculwa kakhulu.
Ngelo xesha, phantsi koxinzelelo oluphezulu, ngenxa yempembelelo ye-lever ye-compound, i-float inokwehla ngokuhambelanayo kunye nomgangatho wamanzi, kwaye iindawo zokuvula kunye nokuvala aziyi kunyanzeliswa ngoxinzelelo oluphezulu njengeevalve zendabuko, ukwenzela ukuba zikhuphe ngokuqhelekileyo. .
8. Kwiimeko ezinesantya esiphezulu sokuhamba, ukuqala rhoqo kwempompo yamanzi kunye nobubanzi be-DN≧100, ivalve yeplagi yesithinteli kufuneka ifakwe kwiivalve yokukhupha umoyaukuze ucuthe impembelelo yamanzi.I-valve yeplagi ye-Buffer kufuneka ikwazi ukukhusela ubuninzi bamanzi ngaphandle kokuchaphazela umthamo omkhulu wokukhupha, ukwenzela ukuba ukusebenza kakuhle kokunikezelwa kwamanzi akuyi kuchaphazeleka, kwaye kuthintele ngokufanelekileyo ukwenzeka kwehamile yamanzi.
