Umsebenzi we-valve yokuphepha ye-steam generator

I-valve yokuphepha ye-steam generator iyi-alamu ezenzakalelayo yokukhulula ukucindezela.Umsebenzi oyinhloko: Uma ingcindezi yebhayela idlula inani elishiwo, ingavula ngokuzenzakalelayo ukukhululeka kwe-steam yokukhipha umoya ukuze kuvinjwe ingcindezi ukuthi ingaqhubeki nokukhuphuka.Ngesikhathi esifanayo, ingakhala i-alamu yomsindo ukuze ixwayise izisebenzi zebhayela ukuze kuthathwe izinyathelo ezidingekayo ukuze kuncishiswe ukucindezela kwebhayela ukuqinisekisa ukuphepha kwe-boiler kanye ne-steam turbine.Ukuphepha.

Lapho umfutho we-boiler wehlela enanini elivumelekile, i-valve yokuphepha ingakwazi ukuzivala ngokwayo, ukuze i-boiler ikwazi ukusebenza ngokuphepha ngaphakathi kwebanga lokucindezela elivumelekile futhi ivimbele i-boiler ekucindezelweni ngokweqile futhi ibangele ukuqhuma.I-valve yokuphepha yakhiwa ikakhulukazi isihlalo se-valve, i-valve core kanye nedivaysi yokucindezela.

Umgomo wokusebenza wevalvu yokuphepha: Ishaneli esesihlalweni sevalvu yokuphepha ixhunywe nesikhala sesitimu sebhayela.I-valve core icindezelwe ngokuqinile esihlalweni se-valve ngokucindezela okukhiqizwa idivayisi yokucindezela.Lapho i-valve ivaliwe;uma umfutho womoya ku-boiler uphakeme kakhulu, i-steam izoba Amandla asekelayo we-valve core nawo anda.Lapho amandla asekelayo emkhulu kunokucindezela kwedivayisi ecindezelayo kumongo we-valve, umgogodla we-valve uyaphakanyiswa kude nesihlalo se-valve, kushiye i-valve yokuphepha isesimweni esivulekile, ngaleyo ndlela kuvumela umusi kubhayela ukuba ukhululwe ukuze ufezeke. impumuzo.Inhloso yokucindezela.Lapho umfutho womoya kubhayela wehla, amandla esitimu kumongo wevalvu nawo ayancipha.Lapho umfutho we-steam ku-generator yesitimu kagesi ubuyela kokujwayelekile, okungukuthi, lapho amandla e-steam engaphansi kokucindezela kwedivayisi yokucindezela kumgogodla we-valve, i-valve yokuphepha izovala ngokuzenzakalelayo.

Ukuze uvimbele izingozi ezinkulu, ukwengeza i-valve yokuphepha ku-generator yesitimu kuyindlela evamile yokuphepha edlala indima ebalulekile ekuphepheni kwebhizinisi.Ukumisa i-valve yokuphepha kungagwema ngempumelelo izingozi zokuphepha ezibangelwa ukuguga kwesilawuli sokucindezela, ukulimala kwamapayipi, njll., futhi kuthuthukise ngempumelelo ukusebenza kokuphepha kwezisetshenziswa.

Ama-valve okuphepha angama-automatic valves asetshenziswa ngokuyinhloko kumajeneretha omusi, imikhumbi yokucindezela (kuhlanganise nezinto zokuhlanza ezinomfutho ophezulu) kanye namapayipi okulawula ukucindezela ukuba kungeqi inani elishiwo futhi adlale indima ebalulekile ekuvikeleni ukuphepha komuntu siqu nokusebenza kwemishini.Izingxenye zokuvula nokuvala ze-valve yokuphepha zisesimweni esivame ukuvaleka ngenxa yamandla angaphandle.Lapho ukucindezela okuphakathi kwempahla noma epayipini likhuphuka ngaphezu kwenani elishiwo, ukucindezela okuphakathi kwepayipi noma okokusebenza kuyavinjelwa ukuba kudlule inani elishiwo ngokukhipha okuphakathi ngaphandle kwesistimu.
