Check valve Danfoss NRV 6S [020-1014] Application: W instalacjach ch?odniczych i klimatyzacyjnych z fluorowcopochodnymi czynnikami ch?odniczymi, na ruroci?gach z zimnym lub gor?cym gazem oraz ruroci?gach ze skroplonym czynnikiem Description: Zawor przelotowy Zapewnia jednokierunkowy przep?yw Zabezpiecza przed przep?ywem czynnika do miejsc o najni?szej temperaturze Konstrukcja zaworu uniemo?liwia drganie t?oka wskutek pulsacji ci?nienia valve Provides a one-way flow Prevents refrigerant flow to the places with the lowest temperatures valve design prevents oscillation of the piston due to pressure pulsations Specification: Maksymalne ci?nienie robocze PS: 28 bar Maksymalne ci?nienie probne p?: 36,4 bar Temperatura czynnika: od -50 do 140C Przy??cze: lutowane 6 mm Minimalny spadek ci?nienia na zaworze (przy ktorym zawor jest w pe?ni otwarty): 0,07 bar KV: 0,56 m3/h Nr kat. Danfoss: 20-1014 Maximum working pressure PS: 28 bar The maximum test pressure p ': 36.4 bar Temperature: -50 to 140 C Connection: Solder 6 mm The minimum pressure drop (during which the valve is fully open): 0.07 bar KV: 0.56 m3/h Ref. Danfoss: 20-1014 Additional information: Przy doborze zaworow zwrotnych do monta?u na t?oczeniu spr??arek nale?y uwzgl?dni? nast?puj?ce ograniczenia: Spadek ci?nienia na zaworze musi by? wi?kszy ni? minimalna ro?nica ci?nie?, przy ktorej zawor zostaje otwarty. Ta uwaga odnosi si? w szczegolno?ci do minimalnej wydajno?ci spr??arki, w ktorej zastosowano regulacj? wydajno?ci. W instalacjach ch?odniczych ze spr??arkami po??czonymi rownolegle korzystne jest stosowanie zaworow typu NRVH (ktore s? wyposa?one w spr??yny mocniejsze ni? zawory NRV). Dzi?ki temu mo?liwe jest unikni?cie problemow zwi?zanych z rezonansem przy obci??eniu mniejszym od nominalnego. Ro?nica ci?nie? na zaworze NRVH nie mo?e by? mniejsza ni? minimalny spadek ci?nienia dla ca?kowicie otwartego zaworu. When selecting valves to be mounted on the compressor discharge should consider the following limitations: photos The pressure drop across the valve must be greater than the minimum pressure differential at which the valve is opened. This comment applies in particular to the minimum capacity of the compressor, which is used to adjust performance. In refrigeration compressors in parallel it is preferred to use valve-type NRVH (which are fitted with springs stronger than the valve NRV). This makes it possible to avoid problems associated with resonance with a load lower than the nominal. Differential pressure NRVH not be less than the minimum pressure drop for fully open valve.
