I-Parallel Slide Gate Valve
Ithini ivalvu yesango lesilayidi esihambisanayo?
I-Parallel Slide Gate Valveumklamo okhethekile we-valve yesango.
Kuyindlela ehlukile yamavalvu esango ohlobo lwe-wedge aguquguqukayo.Idiski ingamahhafu amabili, intwasahlobo ecindezelwe i-Inconel X750 ilayishiwe, leso sihlalo emasongweni ezihlalo ezihambisanayo.Idiski "iyaslayida" lapho ithinta izihlalo, yingakho igama.
Ama-disc axhumene unomphela namasongo esihlalo, athola uphawu oluqinile ngenxa yesiphethu se-inconel esivundlile esitholakala phakathi nangaphandle kosizo lwesistimu yokushadisa.
Indlela yokuvalayama-valve esango lama-slide ahambisanayo.
- Lapho ingcindezi yepayipi noma umehluko wengcindezi wezinhlangothi ezimbili mncane, isiphethu esicindezelwe sizophusha ama-disc emasongweni okuvala, wukuvalwa kokuqala kwamavalvu esango lama-slide ahambisanayo ngaphansi kwezimo zengcindezi ephansi.
- Lapho umfutho wepayipi ukhuphuka, ukucindezela komugqa okwandayo kuzophusha i-disc iringi yesihlalo ngamandla ohlangothini lwengcindezi ephansi, okudala uphawu lwesibili.Ukuphakama kwengcindezi emaphakathi, kuba ngcono ukusebenza kokuvala
Ngakho-ke lolu hlobo lwe-valve lusetshenziswa kakhulu ekucindezelweni okuphezulu nasezinsizeni zokushisa eziphakeme ezifana ne-steam kanye namanzi okuphakelayo.
Izinzuzoyevalvu yesango lesilayidi esihambisanayo ngokumelene nomkhiqizo wohlobo lwe-wedge yendabuko yile:
- Ama-disc we-parallel slide gate valve ngeke avimbe endaweni evaliwe, kuyilapho kungenzeka ngenhlobo ye-wedge evaliwe ngomugqa ekushiseni futhi yavulwa lapho umugqa ubanda.
- I-torque yokuvula/yokuvala ye-valve yesango lesilayidi esihambisanayo iphansi kakhulu kunevalvu yohlobo lwe-valve ye-valve yesango ehambisanayo, okuholela kuma-actuator amancane kanye nezinhlelo zokuvula ezingabizi kakhulu.
- Isici "sokuslayida" sigcina ukungcola kude nezindawo zokuvala.

Izici Zokuklama
- Ukuvala okuqinile kufinyelelwe ngokucindezela kolayini—hhayi kusukela esenzweni sokubopha ngomshini ngakho-ke kususa ukubopha okushisayo
- Ukwehla kwengcindezi encane
- Amadiski ayaziqondanisa.
- Idiski limbozwe ngengxubevange yobuso obuqinile i-Stellite Gr6.
- I-Bi-directional ivaliwe ku-API 598
- Isenzo sokuhlanza ngokwakho phakathi kwediski nesihlalo
- Ukuhlelwa kwe-Bypass kuyatholakala
- Itholakala ngezinga lokushisa eliphakeme le-carbon steel, i-chrome-moly steel, nezinto zokwakha zensimbi engagqwali: ASTM A216 GR WCB, ASTM A217 GR WC6, ASTM A217 GR, WC9, kanye ne-ASTM A351 GR CF8M.
- Itholakala ku-opharetha okwenziwa ngesandla, noma ifakwe isiqalisi esifanelekayo ozikhethele sona

I-Disc ne-Spring ye-parallel slide gate valve:intwasahlobo ecindezelwe ku-inconel X750 ibekwe phakathi kwamadiski amabili endaweni efanayo.
Insika nebhuloho i-BBOSY yevalvu yesango lesilayidi esihambisanayo:Idizayini ye-BBOSY yensika nomakoti, i-York yakhelwe ngezinsika zensimbi ezingu-2 noma ezi-4, kuya ngobubanzi be-valve.
Ukuhlolwa kwe-Hydraulic ye-NORTECH Parallel Slide Gate Valve
Ukuhlolwa kwamavalvu esango lama-slide ahambisanayo.
- ukuhlolwa kwegobolondo izikhathi ezingu-1.5 zokucindezela okulinganiselwe
- ukuhlolwa kwe-low pressure seal enomoya ongu-0.6 Mpa
- ukuhlolwa kwe-low pressure seal ngamanzi 0.4 Mpa
- ukuhlolwa kwe-middle pressure seal kusuka ku-0.4 Mpa kuya ku-1.0Mpa
- ukuhlolwa kwe-high pressure seal izikhathi ezingu-1.1 zokucindezela okulinganiselwe
Umbukiso Womkhiqizo:
Isetshenziswa kuphi Ivaluvu Yesango Leslayidi Esihambisanayo?
I-Parallel Slide Gate Valve isetshenziswa kabanzi emkhakheni wamakhemikhali, uphethiloli, igesi yemvelo, oi-il kanye ne-wellhead device yokukhiqiza igesi yemvelo, amapayipi okudlulisa nokugcina (Class150~2500/PN1.0~42.0MPa, izinga lokushisa lokusebenza -29~450℃), amapayipi anezinhlayiya ezimisiwe, ipayipi legesi yasemadolobheni, ubunjiniyela bamanzi. ukuhlukaniswa nokudluliselwa kokugeleza ohlelweni lwamapayipi noma ingxenye lapho ivaliwe, ngezinye izikhathi ingafakwa endaweni yepompo ukuze kulawulwe noma kulawulwe ukugeleza.
