Uhlu lweeValve zeBhola ezinkulu: Iintlobo kunye neempawu

Uhlu lweeValve zeBhola eziKhulu: Iintlobo, Iimpawu, kunye nezicelo

Iivalvu zebhola ezinkulu, ezaziwa ngokubaiivalvu zebhola ezinkulu, ziivalvu ezikhethekileyo ezenzelwe iinkqubo zemibhobho ekude. Ezi valve zibalulekile ekulawuleni iinkqubo zolwelo olunoxinzelelo oluphezulu, oluhamba kakhulu, oluhlala lufakelwa kwiindawo zokuphela kwemibhobho ukulawula okanye ukuvala ukuhamba kolwelo. Njengoko ububanzi bungaphezulu kwe-intshi ezi-2, zahlulwe ngolu hlobo lulandelayo:

Uhlu lweeValve zeBhola ngokobukhulu

1. Iivalvu zeBhola ezincinci: Ububanzi obuqhelekileyo ≤ 1 1/2 intshi (40 mm).

2. Iivalvu zeBhola eziPhakathi: Ububanzi obuqhelekileyo 2 Inch – 12 Inch (50-300 mm).

3. Iivalvu zeBhola ezinkulu zobungakanani: Ububanzi obuqhelekileyo yi-14 Inch – 48 Inch (350-1200 mm).

4. Iivalvu zeBhola ezinkulu kakhulu: Ububanzi obuqhelekileyo ≥ 56 Inch (1400 mm).

Olu hlu luqinisekisa ukhetho olufanelekileyo lweevalvu kwiimfuno ezahlukeneyo zemibhobho.

Amanqaku aphambili:

- Iivalvu zeBhola eziQokelelweyo ezidadayo vs. Trunnion: Ngelixa iivalvu zebhola zahlulwe ngokweentlobo ezidadayo nezizinzileyo,iivalvu zebhola ezinkulusebenzisa jikeleleivalvu yebhola efakwe kwi-trunnionuyilo lokuphucula uzinzo.

- Iindlela zokuqhubaIivalvu zebhola ezifakwe kwiTrunnion zihlala zidibanaiibhokisi zegiya zevalvu yebhola, ii-actuators ze-pneumatic zevalvu yebholaokanyeii-actuators zombane zevalvu yebholaukuzenzekela kunye nolawulo lwe-torque.

Iimpawu zeSakhiwo seeValve zeBhola ezinkulu

Iivalvu zebhola ezinkuluzenzelwe ukuqina nokuchaneka. Izinto eziphambili ziquka:

- Umzimba weValve: Igcina ibhola kwaye iqinisekisa ukuhamba kolwelo ngaphandle komthungo.

- Ibhola yeValve yeBhola: Aibhola efakwe kwi-trunnionuyilo lunciphisa ukuguguleka kwaye luqinisekisa ukutywinwa okuthembekileyo.

- Isitywina Sezihlalo Ezimbini: Iphucula ukuthembeka kokutywina ngesakhiwo esinezigaba ezimbini.

- Ukuhambelana kweStem kunye neActuator: Ixhasa ukuhlanganiswa kunyeii-actuators ze-pneumatic zevalvu yebholaokanyeii-actuators zombane zevalvu yebholayokulawula kude.

- Ukulinganisela Uxinzelelo: Yehlisa i-torque yokusebenza, yenza kube lula ukusebenza kwevalvu.

Iiparameter zobugcisa zeevalvu zebhola ezinkulu

- Izinto zeValve: Intsimbi yeKhabhoni (iWCB, iA105, iLCB, iLF2, iWC6, iF11, iWC9, iF51),

Intsimbi Engagqwaliyo (CF8, F304, CF8M, 316, CF3, F304L, CF3M, CF316L)

Intsimbi Engagqwaliyo Ephindwe Kabini (4A, 5A, 6A),I-Aluminiyam yobhedu, iMonel, kunye nezinye izinto ezikhethekileyo ze-alloy.

- Uluhlu lobungakanani bevalvu: 14 Inch – 48 Inch (350-1200 mm)..

- Uhlobo loqhagamshelo: Kukho iindlela ezimbini zoqhagamshelo: i-flange kunye ne-clamp.

- Indawo yoxinzelelo: pn10, pn16, pn25, njl.

- Izixhobo zombane ezisebenzayo: zilungele amanzi, umphunga, ukumiswa, ioyile, igesi, i-acid ebuthathaka kunye ne-alkali media, njl.

- Uluhlu lobushushu: ubushushu obuphantsi buyi -29℃ ukuya kwi-150℃, ubushushu obuqhelekileyo buyi -29℃ ukuya kwi-250℃, ubushushu obuphezulu buyi -29℃ ukuya kwi-350℃.

Iingenelo zeeValve zeBhola ezinkulu

1. Ukumelana nolwelo oluphantsi: Ilinganisa ububanzi bombhobho ukuze kuncitshiswe ukulahleka kwamandla.

2. Ukutywina Okuqinileyo: Isebenzisa iipolymers eziphambili ukuze isebenze kakuhle ekungavuzini, ilungele iinkqubo zokucoca umoya.

3. Ukusebenza okululaUkujikeleza kwe-: 90° kwenza kube lula ukuvula/ukuvala imijikelo ngokukhawuleza, ehambelana nokuzisebenzela.

4. Ubude bexesha elide: Iingcingo zokuvala ezinokuthi zitshintshwe zandisa ubomi benkonzo.

Usetyenziso lweeValve zeBhola eziKhulu

Iivalvu zebhola ezinkuluazinamsebenzi xa:

- Ioyile kunye neGesi: Imigca yemibhobho kunye neenethiwekhi zokusasazwa kwezixhobo.

- Unyango lwamanzi: Iinkqubo zoomasipala ezihamba ngokukhawuleza.

- Izityalo zoMbane: Ulawulo lokupholisa kunye nomphunga.

- Ukucubungula iikhemikhali: Ulawulo lolwelo oludlakadlaka.

Iingcebiso zoFakelo kunye noLondolozo

1. Ufakelo: Qinisekisa ukuba imibhobho ihambelana, iiflanges ezilinganayo, kunye neendawo zangaphakathi ezingenayo inkunkuma.

2. Ulondolozo:

– Hlola rhoqo izitywini kunye nee-actuator (umz.,ibhokisi yegiya yevalvu yebhola, iinkqubo zomoya/zombane).

– Tshintsha izitywini ezigugileyo ngokukhawuleza.

– Coca ii-internal zevalvu usebenzisa iindlela ezingarhawuzeliyo.

Kutheni Ukhetha Umenzi weValve yeBhola yaseTshayina

Njengeumenzi wevalvu yebhola ohamba phambili, iTshayina inikezela ngobunjineli obuphambili, izisombululo ezingabizi kakhulu, kunye nemveliso eqinisekisiweyo yi-ISO.iivalvu zebhola ezifakwe kwi-trunnionkwaye uyilo oluhambelana ne-actuator luhlangabezana nemigangatho yehlabathi yokuthembeka nokusebenza.
