I-valve ezilawulayo ezisebenza ngokwakho iyivalvu esetshenziselwa ukulawula umfutho wamanzi, izinga lokugeleza, nezinga lokushisa. Ingakwazi ukulungisa ngokuzenzakalelayo ukucindezela kokuphumayo ngokusekelwe ezinguqukweni zengcindezi yokungena ukuze igcine inani lokucindezela eliqhubekayo. Lolu hlobo lwe-valve lusetshenziswa kabanzi emikhakheni yezimboni, njengamakhemikhali, i-petroleum, amandla, njll.
Ukucindezela okungaguquki okuzenzakalelayo, ukucindezela okuzinzile emuva, izinga lokugeleza, kanye ne-steam yokunciphisa i-valve yamapayipi e-nitrogen kuwuhlobo olukhethekile lwevalvu ezilawulayo ezisebenza ngokwazo esetshenziswa kakhulu ezinhlelweni zamapayipi e-nitrogen. Ingakwazi ukulungisa ngokuzenzakalelayo izinga lokucindezela nokugeleza kwe-nitrogen ukuze kugcinwe inani eliqinile lokucindezela emuva. Lolu hlobo lwe-valve ngokuvamile luqukethe izingxenye ezifana nomzimba we-valve, isembozo se-valve, isihlalo se-valve, i-valve disc, intwasahlobo, njll.
Ithebula lokuqhathanisa usayizi wemodeli:
|Imodeli | i-diameter yegama (DN) | indlela yokuxhumana | ingcindezi yokusebenza (MPa) | okuphakathi okusebenzayo|
|— |. ——– |
|ZL-1 | 15-50 | uxhumano lwe-flange | 0.6-1.6 | igesi ye-nitrogen |
|ZL-2 | 50-80 | uxhumano lwe-flange | 1.0-2.5 | igesi ye-nitrogen |
|ZL-3 | 80-150 | uxhumano lwe-flange | 1.6-4.0 | igesi ye-nitrogen |
|ZL-4 | 150-200 | uxhumano lwe-flange | 2.5-6.4 | igesi ye-nitrogen |
|ZL-5 | 200-300 | uxhumano lwe-flange | 4.0-10.0 | igesi ye-nitrogen |
Ubukhulu bemodeli engenhla ngezereferensi kuphela, futhi ukukhetha okukhethekile kufanele kunqunywe ngokusekelwe ezimweni zangempela zokusebenza kanye nezidingo.
