Kutshanje, i-Jinbin workshop igqibezele uluhlu lwee-odolo zeevalvu zebhola ezidityanisiweyo ngokupheleleyo.ivalvu yebhola edityanisiweyo ngokupheleleyoyamkela isakhiwo esidibeneyo esidibeneyo. Umzimba wevalvu wenziwe ngokuhlanganisa ii-hemispheres ezimbini. Icandelo elingaphakathi elingundoqo yibhola enomngxuma ojikelezayo, oqhagamshelwe kwi-actuator yangaphandle ngesiqu sevalvu. Xa isebenza,i-flange yevalvu yebholaIsiqu siqhutywa ukuba sijikeleze ngesiphatho, ibhokisi yegiya okanye isixhobo sombane/somoya.

Iingenelo zokusebenzisa imboni yevalvu yebhola edibeneyo ngokupheleleyo:

1. Isakhiwo esithembekileyo kunye nokusebenza okuqinileyo kokutywina

Inkqubo yokuwelda iyonke isusa iingozi zokuvuza koqhagamshelo lweflange yendabuko kwaye ifanelekile kwiimeko ezinzima zokusebenza ezifana noxinzelelo oluphezulu, oluvuthayo noluqhumayo (umzekelo, uxinzelelo lwemibhobho yegesi yendalo lunokufikelela ngaphezulu kwe-10MPa). Izinto zokutywina azigugi kwaye zinobomi benkonzo obungaphezulu kweminyaka eli-10, nto leyo enciphisa amaxesha okugcinwa.

2. Ukumelana nokuhamba kwamanzi okuphantsi kunye nokuhamba ngokupheleleyo

Umngxuma ongqukuva uhambelana nobubanzi bangaphakathi bombhobho, kwaye ukumelana nokuhamba kwamanzi kombane yi-1/10 kuphela yobo bombhobho obufanayo, nto leyo enciphisa ukusetyenziswa kwamandla. Ifanelekile ngokukodwa ekuthuthweni okuhamba ngamanzi amaninzi (umzekelo, ububanzi bombhobho wombhobho weoyile eluhlaza bungafikelela kwi-1200mm).

3. Ayinakumelana nokugqwala kwaye iyakwazi ukumelana neemeko ezinzima

Umzimba wevalvu yebhola engenasici ugqunywe ngentsimbi engenasici okanye intsimbi yekhabhoni ethintela ukugqwala (njenge-epoxy resin), enokumelana nokugqwala komhlaba kunye nokukhukuliseka kwamanzi olwandle, kwaye ifanelekile kwiimeko ezinzima ezifana naphantsi komhlaba nangaphantsi kwamanzi.

4. Kulula ukuyisebenzisa kwaye iindleko zokugcina ziphantsi

Ukujikeleza nge-90° kunokugqiba ukuvula nokuvala. Xa zidityaniswe nenkqubo yolawulo oluzenzekelayo, ulawulo olukude lunokufezekiswa. Izakhiwo ezidityanisiweyo zinciphisa iindawo ezihambayo, zinezinga eliphantsi lokusilela, kwaye umjikelo wolondolozo unokwandiswa ukuya kwiminyaka engaphezu kwemihlanu.

Iimeko ezithile zesicelo sevalvu yebhola eneenjini ezidityanisiweyo ngokupheleleyo:

Inkqubo yemibhobho yomgama omde

Ukuhanjiswa kwegesi yendalo – kusetyenziswa kwiindlela zegesi yendalo ezisetyenziswa elunxwemeni (njenge-West-East Gas Pipeline) kunye nemibhobho yokuhanjiswa kwegesi engaphantsi kwamanzi, inokumelana noxinzelelo oluphezulu kwaye iqinisekise ukuvalwa kwexesha elide ukuthintela iingozi zokhuseleko ezibangelwa kukuvuza kwegesi yendalo.

Ukuthuthwa kweoyile ekrwada/ioyile ecociweyo – Ukulawula indlela yokuhamba kwesixhobo kwimibhobho yeoyile enqumla umda, uyilo olupheleleyo lunciphisa ukugcinwa kweoyile kunye nokwehla koxinzelelo, kwaye luphucula ukusebenza kakuhle kothutho.

2. Iinethiwekhi zegesi kunye nemibhobho yokufudumeza ezidolophini

Iyagqunywa ize ifakwe kumbhobho omkhulu wegesi wasezidolophini ukuze ijongane nokuhlaliswa komhlaba kunye notshintsho lobushushu kunye nokunciphisa umngcipheko wokuvuza. Lawula ukuhamba kwamanzi ashushu kwinkqubo yokufudumeza ephakathi, kwaye imelane noxinzelelo oluphezulu (1.6MPa) kunye nobushushu obuphezulu (120℃).

3. Intsimi yemizi-mveliso

Ishishini leekhemikhali: Ukuthutha izinto ezirhabaxa ezifana nee-asidi ezinamandla kunye nee-alkali ezinamandla. Izinto zentsimbi engatyiwayo kunye nezakhiwo zesinyithi eziqinileyo ziqinisekisa ukhuseleko (ezifana ne-hydrochloric acid kunye nemibhobho ye-caustic soda).

Isinyithi kunye namandla: Inganqumla ngokukhawuleza ukuhamba kwegesi kwimibhobho yegesi ye-blast oven okanye ilawule izinga lokuhamba kwimibhobho yamanzi okupholisa yezityalo zamandla obushushu, ivumelane nobushushu obuphezulu (ngaphezulu kwe-300℃) kunye neendawo ezinothuli.

4. Ubunjineli boLwandle kunye neenqanawa

Isetyenziswa kwimibhobho yeoyile esecaleni kolwandle nakwiinkqubo zepetroli zenqanawa, imelana nokugqwala kwamanzi olwandle kwaye iyakwazi ukumelana nokungcangcazela kweenqanawa, kwaye ihambelana nemigangatho yamazwe ngamazwe efana ne-API 6D.

Ivalvu yebhola edityanisiweyo ngokupheleleyo i-Pn16, enokuthembeka kwayo okuphezulu, iindleko zokulungisa eziphantsi kunye nokuzivumelanisa ngokubanzi neemeko zokusebenza, iye yaba yinxalenye ebalulekileyo yolawulo ekudlulisweni kwamandla, iinkqubo zoshishino kunye nokwakhiwa kweziseko zophuhliso, ingakumbi engenakutshintshwa kwiinkqubo ezinkulu zemibhobho ezifuna ukusebenza okuzinzileyo ixesha elide.
