Ama-valve esango le-pressure seal abonakala nge-wedge ehambayo, enyakaziswa ngokusebenza kwe-stem nut.I wedge ihamba perpendicular isiqondiso ukugeleza.
Ama-valve esango anomklamo wokuvala kabili, ngokuvamile abe nokwehla kwengcindezi encane lapho evuleke ngokugcwele, anikeze ukuvala okuqinile lapho kuvalwe ngokugcwele.
Amavalvu esango lophawu lokucindezela asetshenziselwa insizakalo yokucindezela okuphezulu, imvamisa ukucindezela okungaphezu kwamabha ayi-100.Isici esiyingqayizivele sebhonethi ye-pressure seal ukuthi i-body-bonnet joint seal iyathuthuka njengoba ingcindezi yangaphakathi ngaphakathi kwevalvu ikhula.
Izicelo eziyinhloko yilezi: imboni ye-petrochemical, ama-steam circuits, ukujikeleza kwebhoyela, ukusetshenziswa kukawoyela negesi, iziteshi zikagesi.
Izinhlobo ezijwayelekile ezisetshenziswayo okuhlangatshezwana nazo yilezi: umusi, i-condensate, amanzi okuphakelayo kubhoyili
Isilinganiso sokucindezela esijwayelekile sevalvu singamaphawundi angama-900, 1,500 no-2,500.
Ububanzi bomklamo we-valve wesango le-JLPV limi kanje:
1.Usayizi: 2” kuya ku-48” DN50 kuya ku-DN1200
2.Ingcindezi: Ikilasi 900lb ukuya ku-2500lb PN160-PN420
3.Material: Insimbi ye-Carbon nensimbi engagqwali nezinye izinto ezikhethekile.
I-NACE MR 0175 anti-sulphur kanye nezinto zensimbi ezilwa nokugqwala
4.Ukuxhumana kuyaphela: ASME B 16.5 ebusweni obuphakanyisiwe(RF), Ubuso obuyisicaba(FF) kanye Nokuhlanganiswa Kohlobo Lwendandatho (RTJ）
I-ASME B 16.25 kuma-butt welding ends.
5.Ubukhulu bobuso nobuso: buvumelana ne-ASME B 16.10.
6.Izinga lokushisa: -29℃ ukuya ku-580 ℃
Amavalvu e-JLPV angenziwa ngazo zonke izinhlobo zezinto ukuze ahlangabezane nezidingo ezahlukene ezivela kumakhasimende, ikakhulukazi ngokwezinga le-NACE.
Ama-valve e-JLPV angafakelwa ama-gear operator, ama-actuator wepneumatic, ama-Hydraulic actuators, ama-Actuator kagesi, ama-bypasses, amadivaysi okukhiya, ama-chainwheels, iziqu ezinwetshiwe nokunye okuningi kuyatholakala ukuze kuhlangatshezwane nezidingo zamakhasimende.
