✧ Incazelo
Imishini inokuqina okuqinile okuphephile futhi okuthembekile, Inyunyana iphetha isihlalo se-valve yesango lodaka kanye nesango livalwe ngohlobo oluhambisanayo lwe-Metal to Metal Sealing, umphumela walo wokuvala muhle, futhi kulula ukuvulwa, Iziphetho ezimbili ze i-valve namapayipi axhunywe ukunyakaza okuyindilinga. Uxhumano olunyakazayo lwendandatho ye-rubber seal efana ne- "O" akuyona imfuneko ephezulu mayelana nokuqondile kwamaphethelo amabili amapayipi, ukusebenza kwawo kophawu kuhle kakhulu ngemva kokufakwa.
Ivalvu yesango Lodaka, enomklamo osezingeni eliphezulu ihlanganisa ubuciko obunembayo kanye nomgomo ofakazelwe wakhiwe ukuze uhlangabezane nezimfuneko zokumba ezinzima endaweni kawoyela yanamuhla.
Ivalvu ihambisana nobukhulu be-flange obujwayelekile kanye nengcindezi yokukala ingcindezi engu-3000 kanye ne-5000 ye-PSI yokusebenza, usayizi ojwayelekile ngu-2", 3", 4", 4"X5", kanye nesevisi yezinga lokushisa efika ku-400°F.
Ukuxhumeka kokuphela kwe-Flanged-Lolu hlobo lokuxhuma ekugcineni aludingi ukujika noma ukushisela i-valve. Ama-flange we-RTJ abalulekile axhunywe kuma-flange amapayipi afanayo nama-bolt namantongomane.
Ukuxhumeka kokuphela okunemicu--lolu hlobo lokuxhumana ekugcineni, oluphinde lubizwe ngokuthi luyisikulufu, lufanele izinhlelo zokusebenza ezifika ku-7500PSI. Ipayipi lomugqa(LP) kanye nemicu engu-8RD iyatholakala.
I-Butt Weld End Connections--lolu hlobo lwezixhumi zokuphela lwakhiwe ukuze lufane noxhumo lokushisela ipayipi. Amaphethelo amabili ane-beveled ahlanganiswe ndawonye futhi ashiselwe endaweni. Ukuxhuma okushiselwe kulungele kangcono izinhlelo zokusebenza lapho ukususwa njalo epayipini kungadingeki.
Isexwayiso sokushisela: Ngaphambi kokushisela, isihlalo kanye nebhonethi seal kumele kukhishwe emzimbeni wevalvu.
