Yintoni iValve yeBhola edadayo: Isikhokelo esipheleleyo seFactory

Yintoni iValve yeBhola edadayo

A ivalvu yebhola edadayoyenye yeentlobo zeiivalvu zebhola, kwaye ehambelanayo yileivalvu yebhola efakwe kwi-trunnion. Ibonisa ibhola engaxhaswayo ebanjwe phakathi kwezihlalo ezibini zokutywina kuphela. Isiqu siqhagamshelana nebhola ngendlela eguquguqukayo, nto leyo eyivumela ukuba "idada." Phantsi koxinzelelo oluphakathi, ibhola ifudukela kwisihlalo esisezantsi, idale isitywino esiqinileyo kwicala lokuphuma.

Izinto eziphambili

• Umzimba weValve yeBhola/iBhonethi: Iindawo eziphambili zevalvu ezithwala uxinzelelo

• Ibhola yeValve yeBhola: Isphere ehamba ngokukhululekileyo enembobo

• Isiqu seValve: Idlulisela i-torque ebholeni

• Izihlalo: Imiphezulu yokutywina kabini

• Izitywino: I-PTFE okanye izinto ezidityanisiweyo

Iinkcukacha zobugcisa

Iimpawu zeSakhiwo eziNjineliweyo zeValve yeBhola edadayo

1. Uyilo lweSihlalo esitywinwa kabini

Umatshini wokulungisa izihlalo osebenzisa i-proprietary low-friction unciphisa i-torque yokusebenza ngelixa uqinisekisa ukusebenza kwe-zero-leakage ngokutywina kwe-bi-directional.

2. Isiqu Esingenakulungelelaniswa

Isiqu esisikiweyo sithintela ukungalungelelani kwesibambo. Isibambo esihambelanayo = Sivuliwe; Isibambo esime nkqo = Sivaliwe.

3. Imingxunya yokutshixa yoKhuseleko

Imingxunya emibini yokutshixa kwiindawo ezivulekileyo/ezivaliweyo ngokupheleleyo ithintela ukwenzeka ngengozi—ibalulekile kwimibhobho enobungozi.

4. Isiqu Esingaphumiyo

Igxalaba elidibeneyo lithintela ukuphuma kwesiqu ngexesha leziganeko zokuxinzelelwa ngokugqithisileyo, ligcina ukuthembeka kwetywina.

5. Inkqubo Echasene Nokungaguquguquki

Imithombo yokumisa umhlaba ikhupha umbane ongashukumiyo oveliswa kukungqubana—ibalulekile kwiindawo ezivuthayo ezifana ne-LNG okanye i-propane.

6. Ulwakhiwo Olukhuselekileyo Emlilweni

Izitywina zesinyithi ezisetyenziswa kwisinyithi ziyabandakanyeka ngexesha lomlilo:

• Ukudibana kwebhola/umzimba kuthatha indawo yezihlalo ezitshileyo

• Izitywino zomlilo zegrafiti ziyanda ukuvala ukuvuza

•I-API 607/6FA iyahambelana

7. Isihlanganisi soMzimba esingavuziyo

Uyilo lweflange edibeneyo lususa ukuxhomekeka kwi-gasket, luthintela ukuvuza kwangaphandle phantsi kweemeko ezinzima.

Izicelo zeShishini

• Inkonzo Jikelele: Amanzi, izinyibilikisi, iiasidi

• Izinto ezibalulekileyo: Ioksijini, i-H₂O₂, i-methane

• Iindawo Ezinzima:

Izityalo zePetrochemical

Imibhobho yegesi yendalo (emelana ne-H₂S)

Iinkqubo zeCryogenic

Uthutho lwe-slurry olunomhlwa ophezulu

IiValve zeBhola ezidadayo Iingenelo vs. Imida

Iingenelo:

✓ Uyilo oluncinci olulungele ukugcinwa

✓ Ukuvalwa okuqinileyo ngamaqamza

✓ Ukumelana nokuhamba kwamanzi okuphantsi

✓ Ukusebenza ngokukhawuleza kwe-90°

Iingxaki:

✘ Ukungqubana kwezihlalo kunciphisa ukusetyenziswa kwe-P/T ephezulu

✘ Ayifanelekanga ukuba itshiswe ngamalahle (ingozi yokuba imijelo ivaleke)

✘ Ifuna ukufakwa ngobuchule

IiProtokholi zoFakelo kunye noLondolozo

Iimfuneko zoFakelo

• Yifake ngokuthe tye kwiindawo ezithe tyaba

• Kuphephe ukuxinana kwamanzi kufutshane nebhola

• Qinisekisa ukuba akukho nto iphazamisayo ekufikeleleni

Uluhlu lokujonga uLondolozo

• Ngekota: Hlola iiringi zebhola/zokukrazula ukuze ubone ukuba azikhukuliswanga na

• Ngonyaka:

Thambisa iibheringi zesiqu

Qinisekisa amaxabiso e-torque

Vavanya izitywino ezingxamisekileyo

• Emva kokucima: Coca umngxuma ukuze kuthintelwe ukungcola okujiyileyo

Ukudada vs.Iivalvu zeBhola eziQokelelweyo zeTrunnion: Uthelekiso loBugcisa

Isikhokelo soKhetho

Khetha iivalvu ezidadayo ukuze zibe zizisombululo ezingabizi kakhulu nezincinci phantsi kweKlasi 600. Khetha iivalvu ezifakwe kwi-trunnion xa uziphatha:

• Uxinzelelo > Iklasi 900

• Imisebenzi rhoqo yokukhwela ibhayisekile

• Imidiya ekhupha umoya okanye ekhukulisayo
