Mapangidwe a 1 inch Globe Valve Class 2500 Pressure Seled Bonnet
Kumanga Bonnet Yosindikizidwa ndi Pressure
Njira Yosindikizira: Imagwiritsa ntchito mawonekedwe a bonati opatsa mphamvu pomwe kukakamiza kwadongosolo kumakakamira chitsulo cha Graphite-Stainless Steel Spiral Wound Gasket pakati pa bonati ndi thupi, kumapangitsa kusindikiza kukhulupirika pamene kukakamiza kwamkati kumakwera.
Zakuthupi: Thupi lachitsulo lopanga (ASTM A105) lokhala ndi chowongolera cholimba cha Stellite 6 chokana kukokoloka pamakina othamanga kwambiri.
Kuwombera kwa Bonnet: Palibe mabawuti akunja; amadalira wotsatira wodzisintha yekha gland ndi tapered wedge system kusunga yunifolomu gasket compression pansi pa matenthedwe njinga.
Malizani Malumikizidwe: Butt weld (BW) imatha pa ASME B16.25, kuwonetsetsa kuti ma weld alumikizana ndi makina opopera kwambiri.
Zofunika Kwambiri
Mapangidwe a Stem: Tsinde lozungulira losakwera lokhala ndi chakumbuyo chakumbuyo kuti asindikize pawiri pomwe ali otseguka.
Chimbale & Mpando: Conical disc-to-seat geometry yokhala ndi malo okhala ndi 30° tapered, kukwaniritsa Class V shutoff pa API 598.
Packing System: Live-loaded Flexible Graphite Packing yolimbikitsidwa ndi mphete ya nyali ya ntchito ya nthunzi/mankhwala mpaka 1000°F (540°C).
Momwe 1 inch Globe Valve Class 2500 Pressure Seled Bonnet Imagwira Ntchito
Mfundo Yogwirira Ntchito
1. Kuwongolera Mayendedwe: Kusuntha kwa mzere wa diski (yoyendetsedwa ndi gudumu lamanja kapena actuator) kumapangitsa kuyenda mwa kusintha malo a annular pakati pa diski ndi mpando.
2. Kusindikiza Koyambitsa Kupanikizika:
- Pamalo ozungulira, kupanikizika koyambirira kwa gasket kumatheka kudzera mwa wotsatira gland.
- Kuthamanga kwamakina kumachulukira (mpaka 2500 PSI), kuthamanga kwamadzimadzi kumayendera pamwamba pa bonnet, kukakamiza gasket kuti igwirizane kwambiri ndi mawonekedwe a bonneti.
3. Kulipira Kwawotentha: Pakusinthasintha kwa kutentha, kukulitsa kwamafuta kwa msonkhano wa bonnet kumasunga kuchuluka kwa gasket, kuteteza kutayikira.
Ubwino wa 1 inch Globe Valve Class 2500 Pressure Seled Bonnet
Zero-Leakage Performance:
- Kusindikiza kothandizidwa ndi kupanikizika kumatsimikizira kuti ntchitoyo sitayikira ngakhale pansi pa kutentha kwambiri / kuthamanga kwa njinga (pa API 602).
- Malo ocheperako okutidwa ndi stellate kuti akokoloke mu ntchito za nthunzi/condensate.
Kukhalitsa Pamikhalidwe Yovuta:
Zomangamanga zachitsulo zomangika zimalimbana ndi nyundo yamadzi ndi kupsinjika kwa cyclic mu makina opangira magetsi opangira magetsi.
BW imathetsa ziwopsezo za kutayikira kwa flange zomwe zimapezeka mumagulu a Class 2500.
Kusamalira Mwachangu:
Bonati yodzilipilira yokha imachotsa bolt re-torquing panthawi yogwira ntchito.
Kulongedza katundu wamoyo kumachepetsa mpweya wothawa (mogwirizana ndi ISO 15848-1).
Kusinthasintha:
Yoyenera kutenthetsa kwambiri nthunzi, kukonza ma hydrocarbon, komanso makina opangira madzi opopera opopera kwambiri.
Mvuvu umasindikiza kapena boneti yotalikirapo kuti muyikemo cryogenic kapena yotentha kwambiri.
