IValve yoMgangatho weSizwe weGlobhu eYilwayo

Uninzi lweengcali zobunjineli ezithenga iivalvu zemibhobho zihlala zinexhala malunga nokuhlangabezana neengxaki. Basenokudibana neemveliso ezinobungakanani obungalunganga obungenakufakwa, okanye iivalve ziphuka ngokukhawuleza emva kokusetyenziswa. Ngokukodwa kwiimeko ezinoxinzelelo oluphezulu kunye nobushushu obuphezulu, nayiphi na imiba ingaba yingxaki kakhulu. Ivalve yethu yeglowubhu esemgangathweni yeSizwe yenzelwe ngokukodwa iimeko ezinzima ngolo hlobo.

Iinzuzo eziphambili

Umzimba wevalvu wenziwe ngentsimbi yekhabhoni eyi-A105N, eyahlukileyo kwimizimba yevalvu eqhelekileyo. Inkqubo yokuqulunqa isusa iziphene ezingabonakaliyo ezifana ne-pores kunye nemingxuma yesanti kwintsimbi, okwenza isakhiwo sibe sikhulu kwaye sinikeze ukwanda ngokuthe ngqo kumandla okunyamezela. Lo mgangatho weglowubhu weglowubhu womgunyathi unokumelana nobushushu obuphezulu be-425 ° C kwaye ungaphakathi koxinzelelo lwe-PN16. Nokuguquguquka koxinzelelo kwimibhobho yomphunga kunokusingathwa ngokuthembekileyo. Umphezulu wokutywina usebenzisa i-Samtler cobalt-based hard alloy welding, ekwaziyo ukunxiba kwaye imelana nemikrwelo. Inokumelana namashumi amawaka okuvulwa kunye nokuvalwa ngaphandle kokuvuza. Isiqu sevalvu sele sifumene unyango olucimayo kunye ne-nitriding, nto leyo eyenza ukuba ikwazi ukumelana nomhlwa. Kwanamajelo eendaba adla ngokudlakadlaka, ayoyiki. Ngaphezu koko, ukupakisha kunokutshintshwa kwi-intanethi ngaphandle kokumisa kunye nokuqhaqha ivalve yonke, ukwenza ukugcinwa kube lula kakhulu.

Iinkcukacha zobugcisa

Le yi-J41H-16C DN25 PN16 abantu abasoloko bebuza ngayo. I-diameter ebizwa ngokuba yi-25mm, uxinzelelo oluqhelekileyo yi-1.6MPa, i-valve body material yi-A105N, indlela yokudibanisa i-standard flange connection, kunye noyilo kunye nokuveliswa kuhambelana ngokupheleleyo nomgangatho wesizwe we-GB12235. Ubude besakhiwo kunye nemigangatho ye-flange yonke ihambelana ne-HG/T20592. Uvavanyo kunye nokuhlolwa kuye kwaphumelela umgangatho we-JB/T9092. Yonke imilinganiselo ilawulwa ngokuchanekileyo, kwaye xa ifunyenwe, inokudityaniswa ngokuthe ngqo kumbhobho ngaphandle kokuguqulwa. Ngaphaya koko, ivalve yethu yeglowubhu esemgangathweni yeSizwe inokuguqulwa ibe yimathiriyeli eyahlukeneyo ngokweemeko zakho zokusebenza. Insimbi engenasici kunye ne-alloy steel ingasetyenziswa. Iyakwazi ukuhlangabezana neemfuno zamajelo ahlukeneyo.

Iinzuzo zokhuphiswano

Xa kuthelekiswa nabakhuphisana nabo, iifektri ezininzi ezincinci zisebenzisa imizimba yevalve ukugcina iindleko. Zisenokubonakala zifana, kodwa kukho imingxuma yesanti ngaphakathi, kwaye ziyavuza emva kokusetyenziswa unyaka omnye okanye emibini. Kwiimeko zoxinzelelo oluphezulu, baqhelene neengozi zokhuseleko. Inkqubo yethu yokubumba, nangona ibiza kakhulu, inamandla omzimba we-valve ngamaxesha angama-1.5 aphezulu kunawo wokuphosa. Ubomi bunokuphindwa kabini. Ivalve yeglowubhu yethu esemgangathweni yeSizwe inokumelana nokhukuliseko kumajelo eendaba aqulathe amasuntswana kwaye ayizukwaphuka lula. Ekuhambeni kwexesha, kubiza kakhulu kwaye ayifuni ukutshintshwa kwe-valve rhoqo, egcina ixesha lokuvelisa.

Kutheni ukhetha thina?

Siyi-Valves ye-Huadu, sele sisebenza kwi-valve yokuvelisa amashumi eminyaka. Zonke iimveliso zethu ziveliswa kumzi-mveliso wethu. Ukususela ekungeneni kwezinto eziluhlaza ukuya ekugqityweni kweemveliso ezigqityiweyo, isinyathelo ngasinye sihlolwe. Asize sisebenzise iimveliso ezikumgangatho ophantsi ukukhohlisa nabani na. Ngaphezu koko, sinesixa esikhulu seemveliso ezisesitokhweni. Le ngcaciso ye-DN25 inokuthunyelwa ngokuthe ngqo kwindawo yokugcina impahla ngaphandle kokuba ulinde umjikelo omde wemveliso. Sikwabonelela ngeenkonzo zokulungisa. Iiflange ezikhethekileyo kunye nezinto ezikhethekileyo zinokuveliswa. Siye sabandakanyeka kwiiprojekthi ezininzi ezinkulu kwaye sinamava amaninzi.
