Iqhaza elibalulekile le-valve yokuvala okuphuthumayo kwe-pneumatic esezingeni eliphansi emkhakheni wegesi yemvelo ewuketshezi: ukuqinisekisa ukuphepha nokukhuthaza ukuthuthukiswa kwezimboni.

Ngokukhula kwesidingo samandla ahlanzekile emhlabeni wonke, i-liquefied natural gas (LNG) isiphenduke indawo eshisayo emakethe yamandla. Ekukhiqizeni, ekugcinweni, ekuthuthweni nasekusetshenzisweni kwegesi yemvelo ewuketshezi, i-valve yokuvala izimo eziphuthumayo ye-cryogenic pneumatic idlala indima ebalulekile ekuqinisekiseni ukusebenza okuphephile kwalo lonke uchungechunge lwezimboni. Leli phepha lizohlaziya ukusetshenziswa kwe-valve yokuvala izimo eziphuthumayo ze-pneumatic eziphuthumayo emkhakheni wegesi yemvelo ewuketshezi ngokombono wochwepheshe, futhi lixoxe ngendima yalo ebalulekile kulo mkhakha. Okokuqala, ukusetshenziswa kwe-valve yokunqamula izimo eziphuthumayo ezisezingeni eliphansi zomoya ohlelweni lokukhiqiza igesi yemvelo enoketshezi Enqubweni yokukhiqiza i-LNG, i-valve yokuvala izimo eziphuthumayo yomoya isetshenziselwa ukunqamula ukunikezwa kwe-LNG kanye negesi ye-feedstock ukuqinisekisa ukuphepha. yenqubo yokukhiqiza. Enqubweni ye-liquefaction, i-valve yokuvala okuphuthumayo ye-pneumatic esezingeni eliphansi ingavimbela ukuvuza kwegesi yemvelo enoketshezi futhi igweme ukungcoliswa kwemvelo kanye nezingozi zokuphepha. Okwesibili, ukusetshenziswa kwe-valve yokunqamula izimo eziphuthumayo zomoya ophansi endaweni yokugcina nokuthuthwa kwegesi yemvelo enoketshezi Enqubweni yokugcinwa nokuthuthwa kwegesi yemvelo enoketshezi, kuyadingeka ukusebenzisa i-valve yokuvala izimo eziphuthumayo yomoya ophansi ukuze uqinisekise ukuphepha kwamathangi okugcina i-LNG nezindawo zokuthutha. Emathangini okugcina e-LNG, ama-valve e-cryogenic pneumatic shutoff ezimo eziphuthumayo asetshenziselwa ukunqamula ukunikezwa kwe-LNG ukuvimbela ukuvuza kwe-LNG. Enqubweni yokuthutha i-LNG, i-valve yokuvala izimo eziphuthumayo ze-pneumatic yezinga eliphansi lokushisa ingavimbela ngokuphumelelayo ukuvuza kwe-LNG ngesikhathi sokuthutha futhi inciphise ingozi yezingozi. Okwesithathu, ukusetshenziswa kwe-valve yokunqanyulwa kwesimo esiphuthumayo sepneumatic esiphuthumayo ekusetshenzisweni kwegesi yemvelo enoketshezi Enqubo yokufaka isicelo segesi yemvelo enoketshezi, njengokukhiqizwa kwamandla kagesi, ukukhiqizwa kwezimboni kanye neminye imikhakha, i-valve yokuvala okuphuthumayo yomoya ephansi nayo iyadlala. indima ebalulekile. Enqubweni yokuphehla amandla kagesi, i-valve yokuvala izimo eziphuthumayo yomoya ophansi yezinga lokushisa eliphansi inganqamula ukuhlinzekwa kwegesi yemvelo ewuketshezi ukuze kuqinisekiswe ukusebenza okuphephile kwesethi yejeneretha. Enqubweni yezimboni, i-valve yokuvala izimo eziphuthumayo ye-pneumatic esezingeni eliphansi ingavimbela ukuvuza kwegesi yemvelo ewuketshezi, inciphise ubungozi bezingozi, futhi ithuthukise ukusebenza kahle kokukhiqiza. Okwesine, ukuthuthukiswa kwe-valve yokunqanyulwa kwezimo eziphuthumayo ze-pneumatic eziphuthumayo emkhakheni wegesi yemvelo e-liquefied Ngokuthuthuka okusheshayo kwemboni yegesi yemvelo ewuketshezi, i-valve yokuvala izimo eziphuthumayo ye-cryogenic pneumatic nayo izoqhubeka nokuthuthuka kwezobuchwepheshe. I-valve yokuvala izimo eziphuthumayo ye-pneumatic yesikhathi esizayo izohlakanipha kakhulu futhi izenzekele, ithuthukise ukuphepha nokusebenza kahle kochungechunge lwezimboni ze-LNG. Ukwengeza, ukusetshenziswa kwezinto ezintsha kanye nobuchwepheshe bokukhiqiza kuzothuthukisa ukusebenza kwamavalvu okuvala izimo eziphuthumayo ze-pneumatic eziphuthumayo ezindaweni ezisezingeni eliphansi lokushisa. Ngamafuphi, ukusetshenziswa kwama-valve okuvalwa kwezimo eziphuthumayo ze-pneumatic eziphuthumayo emkhakheni wegesi yemvelo ewuketshezi kudlala indima ebalulekile ekuqinisekiseni ukusebenza okuphephile kwalo lonke uchungechunge lwezimboni. Ngokuqhubeka okuqhubekayo kwesayensi nobuchwepheshe, ukusebenza kwe-valve yokunqamula izimo eziphuthumayo ze-pneumatic esezingeni eliphansi kuzoqhubeka nokuba ngcono, kunikeze ukwesekwa okuthembekile ekuthuthukisweni kwemboni yegesi yemvelo ewuketshezi.
