Iyini i-Floating Ball Valve: Umhlahlandlela Ophelele Wefektri

Iyini i-Floating Ball Valve

A ivalvu yebhola elintantayoingenye yezinhlobo zeamavalvu ebhola, futhi okuhambisanayo ngukuthiivalvu yebhola efakwe ku-trunnion. Iqukethe ibhola elingasekelwa elibanjwe phakathi kwezihlalo ezimbili zokuvala kuphela. Isiqu sixhuma kalula nebhola, okulivumela ukuthi "lintante." Ngaphansi kwengcindezi ephakathi, ibhola liyasuka liye esihlalweni esingezansi komfula, okwenza kube nokuvala okuqinile ohlangothini lokukhipha.

Izingxenye Eziyinhloko

• Umzimba we-Ball Valve/i-Bonnet: Izingxenye eziyinhloko zevalvu ezithwala ingcindezi

• I-Ball Valve Ibhola: I-sphere ehamba ngokukhululeka enembobo

• Isiqu se-Valve: Idlulisela i-torque ebholeni

• Izihlalo: Izindawo zokuvala ezimbili

• Izimbonakaliso: I-PTFE noma izinhlanganisela eziqinisiwe

Imininingwane Yobuchwepheshe

Izici Zesakhiwo Ezithuthukisiwe ze-Floating Ball Valve

1. Umklamo Wesihlalo Esivala Kabili

Umshini wokulungisa izihlalo osebenza ngokuzikhandla ophansi unciphisa i-torque yokusebenza ngenkathi kuqinisekiswa ukusebenza kokuvuza okungenazo iziphazamiso ngokuvala okuqondiswayo okubili.

2. Isiqu Esivikela Ukuhambisana

Isiqu esisikiwe ngendlela eyisicaba sivimbela ukungalungi kwesibambo. Isibambo esihambisanayo = Sivulekile; Isibambo esiqondile = Sivaliwe.

3. Izimbobo Zokukhiya Zokuphepha

Izimbobo ezimbili zokukhiya ezindaweni ezivulekile/ezivaliwe ngokuphelele zivimbela ukusebenza ngengozi—okubalulekile kumapayipi ayingozi.

4. Isiqu Esingavumeli Ukuqhuma

Ihlombe elihlanganisiwe livimbela ukuphuma kwesiqu ngesikhathi semicimbi yokucindezela ngokweqile, ligcina ubuqotho besivalo.

5. Uhlelo Olulwa Nokuqina

Iziphethu eziphansi zikhipha ugesi ongaguquki okhiqizwa ukungqubuzana—okubalulekile ezintweni ezivuthayo njenge-LNG noma i-propane.

6. Ukwakhiwa Okuphephile Emlilweni

Izimbozo zensimbi kuya kwensimbi ziyabandakanyeka ngesikhathi somlilo:

• Ukuthintana kwebhola/nomzimba kuthatha indawo yezihlalo ezishile

• Izimpawu zomlilo ze-graphite ziyanda ukuze zivimbele ukuvuza

•I-API 607/6FA ithobela

7. Ilungu Lomzimba Elingavuzi Kakhulu

Umklamo we-flange oxhumeneyo uqeda ukuncika kwe-gasket, uvimbele ukuvuza kwangaphandle ngaphansi kwezimo ezimbi kakhulu.

Izicelo Zezimboni

• Isevisi Ejwayelekile: Amanzi, izinyibilikisi, ama-asidi

• Izinto Ezibalulekile: I-Oxygen, i-H₂O₂, i-methane

• Izindawo Ezinzima:

Izitshalo ze-Petrochemical

Amapayipi egesi yemvelo (amelana ne-H₂S)

Izinhlelo ze-Cryogenic

Ukuthuthwa kwe-slurry okugqwala kakhulu

Ama-Floating Ball Valve Izinzuzo vs. Ukulinganiselwa

Izinzuzo:

✓ Idizayini encane evumelana nokugcinwa

✓ Ukuvala okuqinile

✓ Ukumelana nokugeleza okuphansi

✓ Ukusebenza okusheshayo okungu-90°

Ububi:

✘ Ukungqubuzana kwesihlalo kunciphisa ukusetshenziswa kwe-P/T ephezulu

✘ Akuyona eyama-slurries (ingozi yokuvaleka kwemisele)

✘ Kudinga ukufakwa okunekhono

Izinqubo Zokufaka Nokulungisa

Izidingo Zokufaka

• Faka ngokuvundlile ezindaweni ezilinganayo

• Gwema ukuzulazula kokugeleza eduze kwebhola

• Qinisekisa ukuthi akukho okuvimbelwe

Uhlu Lokuhlola Lokulungisa

• Ngekota: Hlola izindandatho zebhola/zokuklwebha ukuze ubone ukuthi azigugi yini

• Njalo ngonyaka:

Gcoba ama-stem bearings

Qinisekisa amanani e-torque

Hlola izimpawu eziphuthumayo

• Ngemva kokuvala: Hlanza imbobo ukuze uvimbele ukuchitheka kwekristalu

Ukuntanta vs.Amavalvu Ebhola Agibele I-Trunnion: Ukuqhathanisa Kobuchwepheshe

Isiqondiso Sokukhetha

Khetha amavalvu antantayo ukuze uthole izixazululo ezingabizi kakhulu nezincane ngaphansi kwe-Class 600. Khetha amavalvu afakwe ama-trunnion lapho uphatha:

• Izingcindezi > Isigaba 900

• Imisebenzi ejwayelekile yokugibela ibhayisikili

• Imidiya ekhuhlayo noma egugulekayo
