Izici Zokuklama Zebhonethi Evaliwe Ye-Globe engu-1 intshi ye-Globe Valve 2500 Pressure Sealed
Ukwakhiwa Kwebhonethi Evaliwe Ngokucindezela
I-Seal Mechanism: Isebenzisa idizayini yebhonethi enamandla okucindezela lapho ingcindezi yesistimu icindezela i-Metallic Graphite-Stainless Steel Spiral Wound Gasket phakathi kwebhonethi nomzimba, ithuthukisa ubuqotho bokuvala njengoba ingcindezi yangaphakathi ikhuphuka.
Okubalulekile: Umzimba wensimbi eyakhiwe (i-ASTM A105) ene-Stellite 6 enobuso obuqinile obunwetshiwe yokulungisa ukuguguleka kwezicelo zokugeleza kwesivinini esikhulu.
I-Bonnet Bolting: Awekho amabhawodi angaphandle; ithembele kumlandeli we-gland ozishintshayo kanye nohlelo lwe-tapered wedge ukuze kugcinwe ukucindezelwa kwe-gasket okufanayo ngaphansi kokuhamba ngebhayisikili okushisayo.
Qeda Ukuxhumana: I-Butt weld (BW) iphela nge-ASME B16.25 ngayinye, iqinisekisa ukuhambisana okugcwele kokungena kwe-weld namasistimu amapayipi okucindezela okukhulu.
Izingxenye Ezibalulekile
I-Stem Design: Isiqu esiphendukayo esingaphumi esinesihlalo sangemuva esibalulekile sokutywinwa okukabili ngesikhathi sezikhundla ezivuliwe ngokugcwele.
I-Disc & Isihlalo: Ijiyomethri ye-Conical disc-to-seat enezindawo zokuhlala ezicijile ezingu-30°, ifinyelela ukuvalwa kwe-Class V nge-API 598 ngayinye.
Ukupakisha System: Ukupakisha kwe-Flexible Graphite okulayishwe bukhoma kuqiniswe indandatho yesibani yesevisi yesitimu/yekhemikhali kufika ku-1000°F (540°C).
Isebenza kanjani i-intshi engu-1 ye-Globe Valve Class 2500 Pressure Sealed Bonnet
Isimiso Sokusebenza
1. Ukulawulwa Kokugeleza: Ukunyakaza okulayini kwediski (okushayelwa isondo lesandla noma i-actuator) kulungisa ukugeleza ngokushintsha isikhala sonyaka phakathi kwediski nesihlalo.
2. Ukuvala Okufakwe Ingcindezi:
- Ezimweni ze-ambient, ukucindezelwa kwe-gasket kokuqala kufinyelelwa ngokulandela indlala.
- Njengoba ingcindezi yesistimu ikhula (kufika ku-2500 PSI), ukucindezela koketshezi kusebenza endaweni ecijile yebhonethi, okuphoqa i-gasket ukuthi ixhumane kakhudlwana nesixhumi esibonakalayo sebhonethi yomzimba.
3. Isinxephezelo Sokushisa: Ngesikhathi sokuguquguquka kwezinga lokushisa, ukunwetshwa okushisayo komhlangano webhonethi kugcina umthwalo we-gasket ongaguquki, ukuvimbela ukuvuza.
Inzuzo yebhonethi evalwe nge-intshi engu-1 ye-Globe Valve Class 2500
Ukusebenza Kwe-Zero-Leakage:
- Ukuvalwa okusizwa yingcindezi kuqinisekisa ukusebenza okungavuzi nangaphansi kokuhamba ngebhayisikili okushisayo/nokucindezela (nge-API 602 ngayinye).
- Izindawo zokungcebeleka ezimbozwe nge-stellite ukuze ziguguleke ezinsizeni ze-steam/condensate.
Ukuqina Ezimweni Ezinzima:
Ukwakhiwa kwensimbi eyenziwe ngomgunyathi kumelana nesando samanzi kanye nezingcindezi zomjikelezo ezinhlelweni zokudlula i-turbine bypass plant.
Iziphetho ze-BW ziqeda ubungozi bokuvuza kwe-flange obujwayelekile ezinsizeni ze-Class 2500.
Ukunakekela Ngempumelelo:
Ibhonethi yokuzinxephezela yona iqeda ukuzulazula kabusha kwebhawodi ngesikhathi sokusebenza.
Ukupakisha okulayishwe bukhoma kunciphisa ukukhishwa kwegesi (okuhambisana ne-ISO 15848-1).
Ukuhlukahluka:
Ifanele isitimu esishisa kakhulu, ukucutshungulwa kwe-hydrocarbon, kanye nezinhlelo zamanzi eziphakelayo zamabhayela anomfutho ophezulu.
Izivunguvungu ozikhethela zona ziyavala noma ibhonethi enwetshiwe yokufakwa okuqondile kwe-cryogenic noma izinga lokushisa eliphezulu.
Imboni ye-Forged Steel Valve Factory:
I-NSW ingumholi weForged Steel Valve Manufacturere-China, sinemishini yokucubungula ezenzakalelayo kanye nemishini yokuhlola eyinkimbinkimbi ukuze siqinisekise ukuthi ungathenga umkhiqizo wamavalvu okusebenza aphezulu.
