Tsim Cov Nta ntawm 1 nti Globe Valve Chav Kawm 2500 Lub Siab Ncauj Lub Ncauj Ncauj
Pressure Sealed Bonnet Construction
Sealing Mechanism: Siv lub siab-energized bonnet tsim qhov system siab compresses ib tug metallic Graphite-Stainless Steel Kauv Wound Gasket ntawm lub kaus mom thiab lub cev, txhim khu kev ruaj ntseg sealing raws li sab hauv siab.
Khoom siv: Forged steel lub cev (ASTM A105) nrog txuas ntxiv Stellite 6 nyuaj-ntsej muag trim rau yaig kuj nyob rau hauv high-ceev txaus daim ntaub ntawv.
Bonnet Bolting: Tsis muaj bolts sab nraud; tso siab rau tus kheej-kho lub caj pas raws li tus kheej thiab tapered wedge system kom muaj kev sib txuam gasket compression nyob rau hauv thermal cycling.
Xaus kev sib txuas: Butt weld (BW) xaus rau ASME B16.25, kom ntseeg tau tias tag nrho kev nkag mus rau weld compatibility nrog high-pressure piping systems.
Cov ntsiab lus tseem ceeb
Stem Tsim: Tsis-nce rotating qia nrog ib qho backseat rau dual sealing thaum lub sij hawm qhib tag nrho.
Disc & Rooj: Conical disc-to-seat geometry nrog 30 ° tapered zaum saum npoo, ua tiav Class V kaw rau API 598.
Packing System: Live-loaded Flexible Graphite Packing txhawb nqa los ntawm lub nplhaib teeb rau chav dej / tshuaj lom neeg kev pabcuam txog li 1000 ° F (540 ° C).
Yuav ua li cas 1 nti Globe Valve Chav Kawm 2500 Lub Siab Sealed Bonnet Ua Haujlwm
Txoj Cai Ua Haujlwm
1. Flow Regulation: Linear tsab ntawv tsa suab ntawm lub disc (tsav los ntawm lub handwheel los yog actuator) modulates ntws los ntawm altering lub annular qhov chaw ntawm lub disc thiab lub rooj.
2. Pressure-Activated Sealing:
- Ntawm ambient tej yam kev mob, thawj gasket compression yog tiav los ntawm lub caj pas raws li.
- Raws li qhov system siab nce (txog 2500 PSI), cov kua dej siab ua rau ntawm lub kaus mom lub ntsej muag lub ntsej muag, yuam lub gasket rau hauv kev sib cuag nrog lub cev-bonnet interface.
3. Thermal Compensation: Thaum lub sij hawm kub hloov pauv, thermal expansion ntawm lub kaus mom lub tog raj kheej tswj cov roj gasket zoo ib yam, tiv thaiv kev xau.
Qhov zoo ntawm 1 nti Globe Valve Chav Kawm 2500 Lub Siab Ntsig Lub Hnab
Zero-Leakage Performance:
- Kev pabcuam kev sib khi ua kom muaj kev ua haujlwm tsis muaj pa tawm txawm tias nyob rau hauv huab cua sov / lub zog siab (ib API 602).
- Stellite-coated trim resorts rau yaig nyob rau hauv chav / condensate daim ntaub ntawv.
Durability nyob rau hauv hnyav tej yam kev mob:
Forged steel siv tiv thaiv dej rauj thiab kev ntxhov siab nyob rau hauv lub zog cog turbine bypass systems.
BW xaus tshem tawm flange to txaus ntshai tshwm sim hauv Chav Kawm 2500 cov kev pabcuam.
Maintenance Efficiency:
Self-compensating bonnet tshem tawm bolt rov torquing thaum ua haujlwm.
Kev ntim khoom nyob rau hauv thiaj li yuav txo tau cov emissions khiav tawm (ua raws li ISO 15848-1).
Versatility:
Haum rau superheated chav, hydrocarbon ua, thiab high-pressure boiler feedwater systems.
Kev xaiv lub tshuab raj foob lossis txuas ntxiv lub kaus mom rau cryogenic lossis high-temperature ntsug installation.
Tau qhov twg los Forged Steel Valve Hoobkas:
NWS is a Leader ofForged Steel Valve Chaw tsim tshuaj pausnyob rau hauv Suav teb, peb muaj automated ua cov cuab yeej thiab sophisticated xeem cov cuab yeej los xyuas kom meej tias koj muaj peev xwm yuav cov khoom zoo li qub.
