Ngaphambi kwekutsi kufakwe ivalve, kuhlolwa kwemandla evalve kanye nekuhlolwa kwekuvala kwevalve kumele kwentiwe ebhentjini lekuhlolwa kwevalve ye-hydraulic. 20% wema valve lanemfutfo lophansi kumele ahlolwe ngekungakhetsi, futsi 100% kumele ahlolwe uma angafaneleki; 100% wemavalvu lasemkhatsini nalasetulu-umfutfo kufanele ahlolwe. Tindlela tekuhlola umfutfo wemavalvu emanti, oyili, umoya, umfutfo, initrogen, njll Tindlela tekuhlola umfutfo wemavalvu etimboni kufaka ekhatsi emavalvu emoya nguleti letilandzelako:
Indlela yekuhlola umfutfo wevalvi yevivane
Kuhlolwa kwemandla e-valve ye-butterfly ye-pneumatic kuyafana naleyo ye-valve ye-globe. Ekuhlolweni kwekusebenta kwekuvala kwe valve ye butterfly, umkhakha wekuhlola kumele wetfulwe kusuka ekugcineni kwekugeleta kwemkhakha, ipuleti le butterfly kumele ivulwe, lomunye umkhawulo kumele uvalwe, bese umfutfo wekujova kumele ufinyelele enanini lelibekiwe; ngemuva kwekuhlola kutsi kute kuvuza lapho kupakishwa khona kanye naletinye timphawu, vala ipuleti levivane, vula lomunye umkhawulo, bese uhlola ivalve yevivane. Kute kuvuza esivalweni sepuleti lokufanelekile. I-valve ye-butterfly lesetjentiselwa kulawula kugeleta ingahle ingahlolwa kutsi iyasebenta yini ngekuvala.
Indlela yekuhlola umfutfo wevalvu yekuhlola
Hlola simo sekuhlolwa kwevalve: i-eksisi ye-disc ye-valve yekuhlola yekuphakamisa isesimeni lesicondzile ekuvundlile; i-axis yesiteshi se-valve check ye-swing kanye ne-axis ye-disc isesimeni lesicishe sihambisane nelayini levundlile.
Ngesikhatsi sekuhlolwa kwemandla, umkhakha wekuhlola wetfulwa kusuka ekungeneni kuya elinanini lelibekiwe, bese lomunye umkhawulo uvaliwe, futsi uyafaneleka kubona kutsi umtimba wevalve kanye nesembonyo sevalve kute kuvuza.
Ekuhlolweni kwekuvala, indlela yekuhlola yetfulwa kusuka ekugcineni kwekuphuma, bese indzawo yekuvala iyahlolwa ekugcineni kwekungena, futsi kute kuvuza ekupakisheni kanye ne gasket lefanelekile.
Indlela yekuhlola umfutfo wevalvu yesango
Kuhlolwa kwemandla evalve yesango kuyafana naleyo yevalve yemhlaba. Kukhona tindlela letimbili tekuhlolwa kwekucina kwevalve yesango.
1Vula lisango kwenta umfutfo ku valve ukhuphuke inani elibekiwe; bese uvala lisango, khipha ivalve yesango ngekushesha, hlola kutsi kukhona yini kuvuza etimphawu letisetinhlangotsini totimbili tesango, noma ujove ngco umkhakha wekuhlola epulagini lesembonyweni sevalve kuya enanini lelibekiwe , hlola timphawu letisetinhlangotsini totimbili tesango. Lendlela lengenhla ibitwa ngekutsi kuhlolwa kwekucindzeteleka lokusemkhatsini. Lendlela akukafaneli isetjentiswe ekuhlolweni kwekuvala kumavalvu esango lanebubanti lobuncane lobungaphansi kwe DN32mm.
2Lenye indlela kuvula lisango kwenta umfutfo wekuhlolwa kwevalve ukhuphukele esigabeni lesibekiwe; bese uvala lisango, uvule umkhawulo munye welipuleti leliyimphumphutse, bese uhlola kutsi indzawo yekuvala iyavuta yini. Ngemuva kwaloko buyela emuva bese uphindza lesivivinyo lesingenhla kuze kube ngulapho sesifanelekile.
Kuhlolwa kwekucina kwekupakisha kanye ne-gasket ye-valve yesango le-pneumatic kutawukwentiwa ngaphambi kwekuhlolwa kwekucina kwesango.
Indlela yekuhlola umfutfo wevalve yekunciphisa umfutfo
1Kuhlolwa kwemandla evalve yekunciphisa umfutfo kuvame kuhlanganiswa ngemuva kwekuhlolwa kwesicucu sinye, futsi kungaphindze kuhlolwe ngemuva kwekuhlanganiswa. Sikhatsi sekuhlolwa kwemandla: 1min ye-DN <50mm; ngetulu kwemizuzu lemibili ye-DN65～150milimitha; ngetulu kwemizuzu lengu-3 ye-DN> 150mm.
Ngemuva kwekutsi le bellows kanye netincenye setishiselwe, faka tikhatsi letingu 1.5 umfutfo lomkhulu we valve yekunciphisa umfutfo, bese wenta luhlolo lwemandla ngemoya.
2Kuhlolwa kwekungangeni kwemoya kutawentiwa ngekuya kwendlela yekusebenta yangempela. Uma uhlola ngemoya noma ngemanti, hlola ngetikhatsi letingu 1.1 tekucindzeteleka lokubitwako; uma uhlola ngemphunga, sebentisa umfutfo lomkhulu wekusebenta lovunyelwe ngaphansi kwekushisa lokusebenta. Umehluko emkhatsini wemfutfo wekungena kanye nemfutfo wekuphuma kudzingeka kutsi ungabi ngaphansi kwa 0.2MPa. Indlela yekuhlola kutsi: ngemuva kwekutsi umfutfo wekungena ulungiswe, kancane kancane lungisa sikulufu sekulungisa sevalve, kute umfutfo wekuphuma ungashintja ngekucophelela futsi uchubeke njalo ngaphakatsi kweluhlu lwemanani laphakeme nalaphansi, ngaphandle kwekuma noma kujamela. Kule valve yekunciphisa umfutfo wemphunga, uma umfutfo wekungena ulungiswa khashane, le valve ivalwa ngemuva kwekuvalwa kwe valve, bese umfutfo wekuphuma ngemanani laphakeme nalaphansi. Ngaphakatsi kwe-2min, kwandza kwemfutfo wekuphuma kufanele kuhlangabetane netidzingo letiseThebulini 4.176-22. Ngesikhatsi lesifanako, iphayiphi ngemuva kwevalve kufanele ibe Ivolumu ihambisana netidzingo letiseThebulini 4.18 kutsi ifaneleke; emavalvu ekunciphisa umfutfo wemanti nemoya, uma umfutfo wekungena usethwe futsi umfutfo wekuphuma ungu zero, le valve yekunciphisa umfutfo iyavalwa kwentela kuhlolwa kwekucina, futsi kute kuvuza kungakapheli imizuzu lemibili lokufanelekile.
Indlela yekuhlola umfutfo wevalvu yemhlaba kanye nevalvu ye-throttle
Kute kuhlolwe emandla e-valve ye-globe kanye ne-valve ye-throttle, le-valve lehlanganisiwe ivame kubekwa kuhlaka lwekuhlolwa kwemfutfo, i-disc ye-valve iyavulwa, le-medium ijovwa ngenani lelibekiwe, bese umtimba we-valve kanye nesembonyo se-valve kuyahlolwa kutsi kujuluka yini futsi kuvuza yini. Kuhlolwa kwemandla kungaphindze kwentiwe ngesicucu sinye. Kuhlolwa kwekucina kwevalve yekuvala kuphela. Ngesikhatsi sekuhlolwa, sicu se-valve se-valve ye-globe sisesimeni lesimile, i-valve disc iyavulwa, umkhakha wetfulwa kusuka ekugcineni lokuphansi kwe-valve disc kuya enanini lelicacisiwe, bese kupakisha kanye ne-gasket kuyahlolwa; ngemuva kwekudlula esivivinyweni, i-valve disc iyavalwa, bese lomunye umkhawulo uyavulwa kute kuhlolelwe kutsi kukhona yini kuvuza. Uma kuhlolwa kwemandla kanye nekucina kwe valve kumele kwentiwe, kuhlolwa kwemandla kungentiwa kucala, bese umfutfo uyancishiswa ube linani lelibekiwe lekuhlolwa kwekucina, bese kupakisha kanye ne gasket kuyahlolwa; ngemuva kwaloko i-valve disc iyavalwa, bese umkhawulo wekuphuma uyavulwa kute kuhlolelwe kutsi ngabe indzawo yekuvala iyavuza yini.
Indlela yekuhlola umfutfo wevalvu yebhola
Kuhlolwa kwemandla kwe-valve yebhola le-pneumatic kufanele kwentiwe esimeni lesivulekile sesigamu se-valve yebhola.
1Kuhlolwa kwekuvala kwevalve yebhola lelintantako: faka levalve esimeni lesivulekile ngesigamu, yetfula umkhakha wekuhlola ngakulolunye luhlangotsi, bese uvala lolunye luhlangotsi; jika ibhola tikhatsi letinyenti, vula umphetfo lovaliwe uma ivalve isesimeni lesivaliwe, bese uhlola kusebenta kwekuvala ngesikhatsi sekupakisha kanye ne gasket ngesikhatsi sinye. Akukafaneli kube nekuvuza. Lendlela yekuhlola ibese yetfulwa kusuka kulolunye luhlangotsi bese lokuhlolwa lokungenhla kuyaphindzeka.
2Kuhlolwa kwekuvala kwevalve yebhola lecinile: ngaphambi kwekuhlolwa, jikisa ibhola tikhatsi letinyenti ngaphandle kwemtfwalo, ivalve yebhola lecinile isesimeni lesivaliwe, bese umkhakha wekuhlola wetfulwa kusuka ekugcineni kuya enanini lelibekiwe; kusebenta kwekuvala kwekuphela kwesingeniso kuhlolwa ngesilinganiso sekucindzeteleka, futsi kuciniseka kwesilinganiso sekucindzeteleka ngu 0 .5 kuya ku 1, libanga liphindvwe ka 1.6 umfutfo wekuhlola. Ngesikhatsi lesibekiwe, uma kungekho simo sekucindzeteleka, siyafaneleka; bese wetfula indlela yekuhlola kusuka kulolunye luhlangotsi, bese uphindza lesivivinyo lesingenhla. Ngemuva kwaloko, faka le valve esimeni lesivulekile ngesigamu, vala totimbili tincenye, bese ugcwalisa umgodzi wangekhatsi nge medium. Hlola kupakisha kanye ne gasket ngaphansi kwemfutfo wekuhlola, futsi akumele kube nekuvuza.
3I-valve yebhola lenetindlela letintsatfu itawuhlolwa kutsi icinile yini esikhundleni ngasinye.
