Muva nje, i-workshop yaseJinbin iqedele iqoqo lama-oda ama-valve ebhola ahlanganisiwe ngokugcwele.i-valve yebhola ehlanganisiwe ngokugcweleyamukela isakhiwo esihlanganisiwe esihlanganisiwe. Umzimba wevalvu wakhiwa ngokuhlanganisa ama-hemispheres amabili. Ingxenye yangaphakathi eyinhloko iyibhola elinembobo eyindilinga, exhunywe ku-actuator yangaphandle ngesiqu sevalvu. Uma isebenza,i-flange ye-valve yebholaIsiqu siqhutshwa ukuze sijikeleze ngesibambo, i-gearbox noma idivayisi kagesi/yomoya.

Izinzuzo zokusebenzisa imboni yamavalvu ebhola ahlanganisiwe ngokugcwele:

1. Isakhiwo esithembekile kanye nokusebenza okuqinile kokuvala

Inqubo yokushisela iyonke isusa izingozi zokuvuza kokuxhumeka kwe-flange yendabuko futhi ifanelekela izimo zokusebenza ezinzima njengokucindezela okuphezulu, okuvuthayo nokuqhuma (isibonelo, ingcindezi yamapayipi egesi yemvelo ingafinyelela ngaphezu kwe-10MPa). Izinto zokuvala azigugi futhi zinempilo yesevisi engaphezu kweminyaka eyi-10, okunciphisa imvamisa yokugcinwa.

2. Ukumelana nokugeleza okuphansi kanye nokuhamba okugcwele

Imbobo eyindilinga ihambisana nobubanzi bangaphakathi bepayipi, futhi ukumelana kokugeleza kwe-medium kuyi-1/10 kuphela yaleyo yepayipi enobude obufanayo, okunciphisa ukusetshenziswa kwamandla. Ifaneleka kakhulu ekuthuthweni okugeleza kakhulu (isibonelo, ububanzi bepayipi yepayipi likawoyela ongahluziwe bungafinyelela ku-1200mm).

3. Ayikwazi ukumelana nokugqwala futhi ivumelana nezimo ezibucayi

Umzimba we-valve yebhola engagqwali umbozwe ngensimbi engagqwali noma insimbi yekhabhoni evikela ukugqwala (njenge-epoxy resin), engamelana nokugqwala kwenhlabathi nokuguguleka kwamanzi olwandle, futhi ifanele izimo eziyinkimbinkimbi ezifana nangaphansi komhlaba nangaphansi kwamanzi.

4. Kulula ukuyisebenzisa futhi izindleko zokulungisa eziphansi

Ukujikeleza okungu-90° kungaqedela ukuvula nokuvala. Uma kuhlanganiswa nohlelo lokulawula oluzenzakalelayo, ukulawula okukude kungafinyelelwa. Izakhiwo ezihlanganisiwe zinciphisa izingxenye ezihambayo, zinezinga eliphansi lokuhluleka, futhi umjikelezo wokulungisa ungandiswa ube ngaphezu kweminyaka emihlanu.

Izimo ezithile zokusetshenziswa kwe-valve yebhola efakwe ngokugcwele enenjini:

Uhlelo lwamapayipi olude

Ukudluliswa kwegesi yemvelo – okusetshenziswa emigqeni ye-trunk yegesi yemvelo esogwini (njenge-West-East Gas Pipeline) kanye nemipayipi yokudlulisa igesi engaphansi kwamanzi, ingamelana nomfutho ophezulu futhi iqinisekise ukuvalwa kwesikhathi eside ukuze kuvinjelwe izingozi zokuphepha ezibangelwa ukuvuza kwegesi yemvelo.

Ukuthuthwa kukawoyela ongahluziwe/kawoyela ocwengekile – Ukulawula indlela yokugeleza kwe-medium emapayipini kawoyela awela imingcele, ukwakheka kwe-full-bore kunciphisa ukugcinwa kukawoyela kanye nokwehla kwengcindezi, futhi kuthuthukisa ukusebenza kahle kwezokuthutha.

2. Amanethiwekhi egesi kanye namapayipi okushisa asedolobheni

Iyagqitshwa futhi ifakwe epayipini elikhulu legesi lasemadolobheni ukuze kulungiswe ukuhlaliswa kwenhlabathi kanye nokushintsha kokushintsha kwezinga lokushisa nokunciphisa ingozi yokuvuza. Lawula ukugeleza kwamanzi ashisayo ohlelweni lokushisa oluphakathi, futhi umelane nomfutho ophezulu (1.6MPa) kanye nokushisa okuphezulu (120℃).

3. Insimu yezimboni

Imboni yamakhemikhali: Ukuthutha izinto ezigqwalisayo ezifana nama-asidi aqinile nama-alkali aqinile. Izinto zensimbi engagqwali kanye nezakhiwo zokuvala eziqinile zensimbi kuqinisekisa ukuphepha (njenge-hydrochloric acid kanye namapayipi e-caustic soda).

I-Metallurgy kanye namandla: Inganqamula ngokushesha ukugeleza kwegesi emipayipini yegesi yesithando somlilo noma ilawule izinga lokugeleza emipayipini yamanzi okupholisa yezitshalo zamandla ezishisayo, ivumelane nezimo zokushisa eziphakeme (ngaphezu kuka-300℃) kanye nezinothuli.

4. Ubunjiniyela Bemikhumbi Nemikhumbi

Isetshenziswa emipayipini kawoyela yesikhulumi sasogwini kanye nezinhlelo zikaphethiloli zemikhumbi, imelana nokugqwala kwamanzi olwandle futhi iyakwazi ukumelana nokudlidliza kwemikhumbi, futhi ihambisana nezindinganiso zomhlaba wonke ezifana ne-API 6D.

I-valve yebhola i-Pn16 ehlanganisiwe ngokugcwele, enokuthembeka kwayo okuphezulu, izindleko zokulungisa eziphansi kanye nokuzivumelanisa nezimo zokusebenza, isibe yingxenye yokulawula eyinhloko ekudlulisweni kwamandla, izinqubo zezimboni kanye nokwakhiwa kwengqalasizinda, ikakhulukazi engenakufakwa esikhundleni ezinhlelweni ezinkulu zamapayipi ezidinga ukusebenza okuzinzile isikhathi eside.
