Igama lomkhiqizo: I-Flanged non-rising stem soft sealing ductile cast iron valve.

Inzuzo yomkhiqizo: 1. Izinto ezinhle kakhulu ukuvala kahle. 2. Ukufakwa okulula ukumelana nokugeleza okuncane. 3. Ukusebenza kwe-turbine okonga amandla.

Amavalvu esango ayingxenye ebalulekile yezimboni ezahlukahlukene, lapho ukulawulwa kokugeleza koketshezi kubalulekile khona. Lawa mavalvu ahlinzeka ngendlela yokuvula noma ukuvala ngokuphelele ukugeleza koketshezi, ngaleyo ndlela alawule ukugeleza futhi alawule ingcindezi ngaphakathi kohlelo. Amavalvu esango asetshenziswa kabanzi emipayipini ethutha uketshezi olufana namanzi namafutha kanye namagesi.

Amavalvu esango le-NRSziqanjwe ngomklamo wazo, ohlanganisa isithiyo esifana nesango esihamba phezulu naphansi ukulawula ukugeleza. Amasango ahambisana nesiqondiso sokugeleza koketshezi ayaphakanyiswa ukuvumela ukudlula koketshezi noma ehliswe ukuze kuvinjelwe ukudlula koketshezi. Lo mklamo olula kodwa osebenzayo uvumela ivalvu yesango ukulawula ukugeleza kahle futhi ivale uhlelo ngokuphelele uma kudingeka.

Inzuzo ephawulekayo yama-valve esango ukwehla kwawo okuncane kwengcindezi. Uma evuliwe ngokugcwele, ama-valve esango ahlinzeka ngendlela eqondile yokugeleza koketshezi, okuvumela ukugeleza okuphezulu kanye nokwehla kwengcindezi okuphansi. Ngaphezu kwalokho, ama-valve esango ayaziwa ngamakhono awo okuvala ngokuqinile, okuqinisekisa ukuthi akukho ukuvuza okwenzekayo lapho i-valve ivaliwe ngokuphelele. Lokhu kuwenza afaneleke ukusetshenziswa okudinga ukusebenza ngaphandle kokuvuza.

Amavalvu esango ahleli ngerabhaasetshenziswa ezimbonini eziningi ezahlukene, okuhlanganisa uwoyela negesi, ukwelashwa kwamanzi, amakhemikhali kanye nezitshalo zikagesi. Embonini kawoyela negesi, amavalvu esango asetshenziselwa ukulawula ukuhamba kukawoyela ongahluziwe kanye negesi yemvelo ngaphakathi kwamapayipi. Izitshalo zokwelapha amanzi zisebenzisa amavalvu esango ukulawula ukuhamba kwamanzi ngezinqubo ezahlukene zokwelapha. Amavalvu esango nawo avame ukusetshenziswa ezitshalweni zikagesi, okuvumela ukulawula ukuhamba komusi noma i-coolant ezinhlelweni ze-turbine.

Nakuba ama-valve esango enikeza izinzuzo eziningi, nawo anemikhawulo ethile. Inkinga enkulu ukuthi asebenza kancane uma kuqhathaniswa nezinye izinhlobo zama-valve. Ama-valve esango adinga ukujika okuningana kwesondo lesandla noma i-actuator ukuze avuleke noma avalwe ngokuphelele, okungadla isikhathi esiningi. Ngaphezu kwalokho, ama-valve esango asengozini yokulimala ngenxa yokuqongelela kwemfucumfucu noma izinto eziqinile endleleni yokugeleza, okubangela ukuba isango livaleke noma libhajwe.

Ngamafuphi, ama-valve esango ayingxenye ebalulekile yezinqubo zezimboni ezidinga ukulawulwa okunembile kokugeleza koketshezi. Amandla awo okuvala anokwethenjelwa kanye nokwehla okuncane kwengcindezi kwenza kube yinto ebalulekile ezimbonini ezahlukahlukene. Nakuba enemikhawulo ethile, ama-valve esango ayaqhubeka nokusetshenziswa kabanzi ngenxa yokusebenza kahle kwawo kanye nokusebenza kahle ekulawuleni ukugeleza.
