Ukusetshenziswa kwe-valve yokushisa okuphezulu ekukhiqizeni amandla ashisayo nakweminye imikhakha

I-valve yokushisa ephezulu iyi-valve esebenza ngaphansi kwezimo zokushisa eziphakeme, ikakhulukazi ezisetshenziswa ku-petroleum, imboni yamakhemikhali, i-metallurgy, i-thermal power generation kanye nezinye izimboni. Ikakhulukazi emkhakheni wokukhiqiza amandla ashisayo, ukubaluleka kwama-valve okushisa aphezulu kubonakala kakhulu, okudlala indima ebalulekile ekuqinisekiseni ukusebenza okuphephile, okuzinzile nokusebenza kahle kwesistimu yamandla. Leli phepha lizohlaziya ukusetshenziswa kwe-valve yokushisa okuphezulu ekukhiqizeni amandla ashisayo neminye imikhakha.

Okokuqala, ukusetshenziswa kwama-valve aphezulu okushisa emkhakheni wokukhiqiza amandla ashisayo
1. Isistimu ye-boiler: Kusistimu yokubilisa yokukhiqiza amandla ashisayo, ama-valve okushisa aphezulu asetshenziswa kuzixhumanisi ezihlukahlukene, njengama-valves e-steam, ama-valve amanzi okuphakelayo okuyinhloko, ama-reheater valves, ama-superheater valves, ama-blowdown valves, njll. Lawa mavalvu okushisa aphezulu asebenza ngaphansi. izinga lokushisa eliphezulu kanye nezimo zengcindezi ephezulu, futhi zinezidingo eziphakeme zokusebenza kwezinga lokushisa eliphezulu, ukumelana nokugqoka nokubekwa uphawu kwezinto.

2. Uhlelo lwe-steam turbine: Ohlelweni lwe-steam turbine, ama-valve okushisa aphezulu asetshenziswa ngokuyinhloko ukulawula indlela ukugeleza nokucindezela kwesitimu, njengama-valve alawulayo, ama-valve okuphepha, ama-valve okuhlola, njll. Lawa mavalvu okushisa aphezulu kudingeka akwazi ukumelana nezinga lokushisa eliphezulu kanye nezindawo zokusebenza ezinomfutho ophakeme, kuyilapho unomsebenzi omuhle wokuvala uphawu nokuzinza.

3. Uhlelo lokupholisa: Esimisweni sokupholisa sezitshalo zamandla ashisayo, ama-valve aphezulu asetshenziswa kakhulu ukulawula ukugeleza nokucindezela kwamanzi okupholisa, njengama-valve amanzi okupholisa, izicupho, njll. Lawa ma-valve aphezulu asebenza ngaphansi kwezimo. izinga lokushisa eliphezulu, ukucindezela okuphezulu kanye nezinga lokugeleza okuphezulu, futhi banezidingo eziphakeme zokumelana ne-oxidation, ukumelana nokugqoka kanye nokuvala impahla yezinto.

Okwesibili, izinzuzo zama-valve okushisa aphezulu ekukhiqizeni amandla ashisayo nezinye izinkambu
1. Amandla okushisa aphezulu: i-valve yokushisa ephezulu inamandla okwanele okushisa okwanele ukugcina izakhiwo ezinhle zemishini ngaphansi kwezimo zokushisa eziphakeme ngaphandle kokuguqulwa noma ukulimala.

2. Ukumelana ne-oxidation: impahla ye-valve yokushisa ephezulu inokumelana okuhle ne-oxidation, ingamelana nokugqwala kwe-oxidation endaweni yokushisa ephezulu, yandise impilo yesevisi ye-valve.

3. Ukumelana nokugqoka: i-valve yokushisa ephezulu inokumelana nokugqoka okwanele ukumelana nokugqoka ngaphansi kwezimo eziphakeme zokushisa ukuze kuqinisekiswe ukusebenza okuzinzile kwesikhathi eside kwe-valve.

4. Ukubeka uphawu: I-valve yokushisa ephezulu inokubekwa uphawu okuhle, ingavimbela ngokuphumelelayo ukuvuza endaweni yokushisa ephezulu, ukuqinisekisa ukusebenza okuphephile, okuzinzile nokusebenza kahle kwesistimu.

I-5, ukuzinza: i-valve yokushisa ephezulu inokuzinza okuhle, ingagcina ukusebenza okujwayelekile ngaphansi kwezimo zokushisa eziphakeme, ukunciphisa izinga lokwehluleka kanye nezindleko zokulondoloza.

I-valve yokushisa ephezulu inezinhlobonhlobo zezicelo ekukhiqizeni amandla ashisayo nezinye izinkambu, okubaluleke kakhulu ukuqinisekisa ukusebenza okuphephile, okuzinzile nokusebenza kahle kwesistimu yamandla. Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe, amavalvu okushisa aphezulu azothuthukiswa ngokuqhubekayo futhi athuthukiswe ngokwezinto zokwakha, ukwakheka, inqubo yokukhiqiza, njll., ukuze ahlangabezane nezidingo zobuchwepheshe ezikhulayo eziqinile emikhakheni efana nokuphehla amandla ashisayo.
