I-Stainless Steel Globe Valves Izici nezinzuzo:
1. Idizayini ye-stem engaphenduki eyingqayizivele ivumelana kalula ne-actuation-- ngemicu ye-Acme enembayo kanye nesiphetho esishisiwe.I-Stainless Steel Valve ilungele ukufakwa okuvundlile.
2. I-Stainless Steel Universal trim: 13Cr stem, 13Cr faced disc, nezihlalo ezibhekene ne-CoCr alloy-- I-API Trim 8 ifanelekela isevisi efika ku-850 F(454 C).Ubuso besihlalo i-CoCr ingxubevange enobuso obuqinile, buphansi, futhi bugqitshwe kuze kube sekugcineni kwesibuko.Isihlalo se-conical sifakwe ngomshini ukuze siqedele phezulu.Idiski eqondiswa umzimba ihlobanisa kahle indawo enobuso obuqinile yediski (enobuso obuqinile obuno-13Cr, ingxubevange ye-CoCr, i-SS 316, noma i-Monel) nengaphezulu lesihlalo somzimba, esigayiwe futhi sigqitshwe kuze kube sekugcineni kwesibuko.Imihlahlandlela yediski inobuso obuqinile ukuze inwebe isikhathi sokuguga sabaqondisi bediski.
3. Umzimba Wensimbi Engagqwali kanye nokusakazwa kwebhonethi kwenziwa ngokunemba ngomshini.Ibhonethi yocezu olulodwa lokuqondanisa okungcono, izingxenye ezimbalwa.
4. Ibhokisi lokugxusha lenziwe ngomshini ukuze liqedele kahle.
5. Umzimba nebhonethi okuhlanganyelwe kwenziwe ngokunembile ukuze kuqedelwe kahle.I-gasket evalwe ngokuphelele.
6. Indlala inokwakhiwa okuyiziqephu ezimbili ukuze iqondaniswe kalula.
7. I-stem nut ejikelezayo ku-Austenitic ductile iron Gr.I-D-2C, ivuseleleka ku-inthanethi.
8. Ingalo ye-torque inciphisa ukuguga emasongweni okupakisha futhi ivumela ukuvala okungcono futhi yehlise i-torque.
9. Amasondo esandla e-Impactor: Amavalvu okuhlola iglobhu kanye nokumisa adinga ama-torque aphezulu okuvala kunamavalvu esango anobubanzi obufanayo besihlalo kanye nesigaba sokucindezela.Indlela yokonga kakhulu yokuvalwa okuqinile isondo lesandla se- impactor.Izigaxa ezimbili eziphonswa ngaphansi kokushaywa kwesondo ngesikhathi esisodwa futhi zinikeza izikhathi ezi-3 - 10 amandla okuvala amasondo ajwayelekile.Amasondo esandla e-Impactor ahlinzekwa ngenketho yomkhiqizi ngaphandle uma kucaciswe ikhasimende.
10. Ama-Flanges: Amakilasi e-ASME: 150-- 300: 116" ubuso obuphakanyisiwe.
11. Amakilasi e-ASME: 600-- 1500: 1/4" ubuso obuphakanyisiwe.
12. Qeda: 125-- 250 AARH yawo wonke amavalvu.
Okulandelayo ezinye izinhlelo zokusebenza ezijwayelekile ze-Stainless Steel Globe Valves:
1. Uhlelo lwamanzi okupholisa oludinga ukulungisa izinga lokugeleza.
2. Isistimu yesibaseli, ukulawulwa kokugeleza, nokuqina kubaluleke kakhulu.
3. Lapho ukuqina nokuphepha kuyizinto ezicatshangelwayo eziyinhloko, ama-high-point vents nama-drain-point-drain.
4. Ukunikezwa kwamanzi, ukudla kwamakhemikhali, i-condenser exhaust kanye ne-exhaust drainage system.
5. Imbobo yokukhipha ibhoyili kanye nepayipi lokudonsa amanzi, imbobo enkulu yokukhipha isitimu kanye nepayipi lokudonsa amanzi, kanye nepayipi lokukhipha isifudumezi.
6. Ama-turbine seals kanye nepayipi lokudonsa amanzi.
7. Isistimu kawoyela wokugcoba i-turbine, njll.
