Incwadi yemiyalelo yentsimbi engagqwali engama-304ivalvu yesango lemelayivalvu yokulawula esisiseko ezinikeleyo yemibhobho yokuthutha udaka lwemigodi. Ilinganiswe kuxinzelelo oluqhelekileyo lwe-1.6MPa, ifumaneka ngobukhulu obuqhelekileyo be-DN100, DN300 kunye ne-DN350, ifanelekile kwiimeko zokusebenza ezinobushushu obuphakathi ≤ 100℃. Yenzelwe ngokukodwa udaka lwemigodi olunamasuntswana aqinileyo kunye neempawu ezinamandla zokukhuhla, le valve isombulula iindawo eziqhelekileyo zentlungu yemizi-mveliso yeevalvu zemveli ezifana nokuxinana rhoqo, ukukrala okukhulu kunye nokusilela kokuvala. Ngomsebenzi ozinzileyo nothembekileyo, iye yaba sisixhobo sokulawula ulwelo esithandwayo kwiiprojekthi zokucubungula izimbiwa zemigodi zehlabathi kunye nokuthutha imisele, ilungelelanisa ngokugqibeleleyo neendawo zokusebenza ezinzima zemigodi.

Le valve inezixhobo zobungcali kunye noyilo lwesakhiwo olulungiselelwe inkonzo yodaka. Umzimba wevalvu yentsimbi engagqwali engama-304 ubonelela ngokumelana nokugqwala okugqwesileyo kunye nokusebenza okuchasene nokukhuhla, uxhathisa ngempumelelo ukukhukuliseka kunye nomonakalo obangelwa kukungcola kweeminerali kwidaka, kwaye uphephe iingxaki zokugqwala kunye nokugqobhoka kweevalvu eziqhelekileyo. Ulwakhiwo lweblade olubhityileyo nolubukhali lunokunqumla kakuhle iintsalela eziqinileyo kunye nokungcola okune-fibrous kwindawo ephakathi, luqinisekisa ukuvulwa nokuvalwa okungenakuthintelwa ngaphandle kokuxinana kwezinto. Isebenzisa i-handwheel drive ecocekileyo, ayifuni iimoto zombane, imithombo yomoya okanye ezinye izixhobo zamandla ezincedisayo. Ukusebenza okulula nokuthembekileyo kwindawo akuyi kuchaphazeleka kukucima kombane okanye ukusilela kokunikezelwa komoya, kuqinisekisa ukusebenza okuzinzileyo kwepayipi unyaka wonke.

Inamandla okusebenza kakuhle kokutywina kunye nokuguquguquka kokufakelwa. Ixhotyiswe ngesakhiwo sokutywina esizicocayo, ivalvu inokukhuhla ngokuzenzekelayo iidipozithi zedaka kunye neentsalela zezimbiwa kumphezulu wokutywina ngexesha lokuvula nokuvala, igcina umphezulu wokutywina ucocekile kwaye isebenza ixesha elide ukutywina ukuthintela ukuvuza okuphakathi. Uqhagamshelo oluqhelekileyo oluneflange luvumela ukufakwa okulula nokusebenzayo, ukuqhaqha kunye nokugcinwa, okufanelekileyo kwiindlela ezincinci nezintsonkothileyo zepayipi kwimigodi engaphantsi komhlaba, kwimigodi evulekileyo kunye namagumbi okumpompa. Ngomlinganiselo woxinzelelo we-1.6MPa, ihlangabezana ngokupheleleyo neemfuno zokuthwala uxinzelelo lwepayipi eziphantsi kunye neziphantsi zokuthutha udaka kwimigodi kunye nokukhupha intsalela.

Xa isetyenziswa ngendlela ebonakalayo, olu luhlu lweevalvu zesango lemela lunciphisa iindleko zokusebenza kwaye luphucula ukusebenza kakuhle kwamashishini emigodi. Umzimba wevalvu encinci uthatha indawo encinci yepayipi, ulungelelanisa kakuhle iiprojekthi ezintsha zemigodi kunye neeprojekthi zokuhlaziya imibhobho emidala. Isakhiwo sokuqhutywa ngesandla sinciphisa kakhulu iindleko zokuthengwa kwezixhobo kunye nokugcinwa ngaphandle kwenkqubo yolawulo lwe-elektroniki eyinkimbinkimbi efunekayo. Izinga layo lokusilela eliphantsi kakhulu linciphisa ngokufanelekileyo amaxesha okugcinwa kunye nokulahleka kokuvalwa kwemveliso. Igubungela iinkcukacha ezininzi ze-DN100, DN300 kunye ne-DN350, ivalvu ihambelana nemibhobho ye-slurry enamazinga ahlukeneyo okuhamba. Ixhasa ukwenziwa ngokwezifiso okukhulu kunye nokunikezelwa kobuninzi ngokuhanjiswa okuzinzileyo ukuhlangabezana neemfuno zokuthengwa kweeprojekthi zemigodi zehlabathi.

Zonke iivalvu zesango le-stainless steel ezingama-304 zenziwe ngokuhambelana nemigangatho yemizi-mveliso yamazwe ngamazwe. Ivalvu nganye ivavanywa ngokungqongqo nge-hydrostatic, ihlolwe ngokutywinwa kunye nokuqinisekiswa kokusebenza ngaphambi kokuba ihanjiswe ukuqinisekisa umgangatho ozinzileyo nothembekileyo. Njengevalvu yokuvala ezinikeleyo nengabizi kakhulu kwiimeko ze-slurry, isetyenziswa kakhulu ekuhleleni i-ore, ekuthuthweni kwe-slurry kunye nonyango lweentsalela ngaphakathi kobushushu obuphakathi be-100℃. Sinikezela ngeemveliso ezisemgangathweni, iinkonzo zokukhetha ezenzelwe wena kunye nezisombululo ezipheleleyo zolawulo lolwelo lwepayipi kumashishini obunjineli bemigodi be-B-end yehlabathi, esebenza njengendlela efanelekileyo yokuphucula iivalvu zemveli kwiimeko zokusebenza kwe-slurry.
