Indima ephambili yobushushu obuphantsi be-pneumatic yokuvala i-valve engxamisekileyo kwintsimi yerhasi yendalo elulwelo: ukuqinisekisa ukhuseleko nokukhuthaza uphuhliso lwamashishini.

Ngokukhula kwemfuno yehlabathi yamandla acocekileyo, irhasi yendalo engamanzi (LNG) iye yaba yindawo eshushu kwimarike yamandla. Kwimveliso, ukugcinwa, ukuthutha kunye nokusetyenziswa kwegesi yendalo engamanzi, i-valve ye-cryogenic pneumatic yokuvala i-emergency idlala indima ebalulekileyo ekuqinisekiseni ukusebenza ngokukhuselekileyo kwekhonkco lezoshishino lonke. Eli phepha liza kuhlalutya ukusetyenziswa kwe-valve ye-low-temperature ye-pneumatic engxamisekileyo yokuvala i-valve kwintsimi yegesi yendalo enolwelo ukusuka kwimbono yengcali, kwaye ixoxe ngendima yayo ephambili kule ntsimi. Okokuqala, ukusetyenziswa kwe-valve ephantsi yokushisa kwe-pneumatic engxamisekileyo yokunqunyulwa kwenkqubo yokuvelisa igesi yendalo enolwelo Kwinkqubo yokuvelisa i-LNG, i-valve ye-pneumatic shutoff engxamisekileyo isetyenziselwa ukunqumla ukunikezelwa kwe-LNG kunye ne-feedstock gas ukuqinisekisa ukhuseleko. yenkqubo yemveliso. Kwinkqubo ye-liquefaction, i-valve ephantsi yobushushu obuphantsi be-pneumatic yokuvala i-value inokuthintela ukuvuza kwegesi yendalo enolwelo kwaye igweme ukungcoliseka kwendalo kunye neengozi zokhuseleko. Okwesibini, ukusetyenziswa kwe-valve ephantsi kwe-pneumatic engxamisekileyo yokusika i-valve kwindawo yokugcina kunye nokuthuthwa kwerhasi yendalo engamanzi Kwinkqubo yokugcina kunye nokuthuthwa kwegesi yendalo enolwelo, kuyimfuneko ukusebenzisa i-valve yokuvala i-value yongxamiseko ephantsi kwe-pneumatic ukuze kuqinisekiswe. ukhuseleko lweetanki zokugcina i-LNG kunye nezibonelelo zothutho. Kwiitanki zokugcina i-LNG, ii-valve ze-cryogenic pneumatic shutoff ezingxamisekileyo zisetyenziselwa ukunqumla ukunikezelwa kwe-LNG ukukhusela ukuvuza kwe-LNG. Kwinkqubo yokuthuthwa kwe-LNG, i-valve yokuvala i-valve yokuvala ngokukhawuleza kwe-pneumatic inokuthintela ngokufanelekileyo ukuvuza kwe-LNG ngexesha lokuthutha kunye nokunciphisa umngcipheko weengozi. Okwesithathu, ukusetyenziswa kobushushu obuphantsi be-pneumatic engxamisekileyo yokusika i-valve kwinkqubo yokusetyenziswa kwegesi yendalo engamanzi Kwinkqubo yokusetyenziswa kwerhasi yendalo enolwelo, efana nokuveliswa kwamandla egesi, imveliso yemizi-mveliso kunye namanye amasimi, i-valve ephantsi ye-pneumatic yokuvala unxunguphalo nayo iyadlala. indima ebalulekileyo. Kwinkqubo yokuveliswa kwamandla ombane, i-valve ephantsi yobushushu obuphantsi be-pneumatic yokuvala i-valufa inokunqumla ukunikezelwa kwegesi yendalo edibeneyo ukuqinisekisa ukusebenza ngokukhuselekileyo kwesethi ye-generator. Kwinkqubo yoshishino, i-valve ephantsi yobushushu obuphantsi be-pneumatic yokuvala i-value inokuthintela ukuvuza kwegesi yendalo edibeneyo, ukunciphisa umngcipheko weengozi, kunye nokuphucula ukusebenza kakuhle kwemveliso. Okwesine, intsingiselo yophuhliso lobushushu obuphantsi be-pneumatic yokusika i-valve engxamisekileyo kwintsimi yerhasi yendalo enyibilikisiweyo Ngophuhliso olukhawulezayo lweshishini legesi yendalo enyibilikisiweyo, ivalve yokuvala i-cryogenic pneumatic emergency iya kuqhubeka nokuqhubela phambili kwitekhnoloji. I-valve ephantsi yobushushu obuphantsi be-pneumatic yokuvala i-valve iya kuba nengqondo ngakumbi kwaye i-automated, iphucula ukhuseleko kunye nokusebenza kakuhle kwe-LNG industry chain. Ukongeza, ukusetyenziswa kwezinto ezintsha kunye nobuchwepheshe bokuvelisa kuya kuphucula ngakumbi ukusebenza kweevalvu ezivaliweyo zobushushu obuphantsi be-pneumatic kwiindawo ezinobushushu obuphantsi. Ngamafutshane, ukusetyenziswa kwe-low-temperature pneumatic emergency valves shutdown kwintsimi ye-liquefied natural gas kudlala indima ephambili ekuqinisekiseni ukusebenza ngokukhuselekileyo kwayo yonke i-industrial chain. Ngenkqubela phambili eqhubekayo yenzululwazi kunye nobuchwepheshe, ukusebenza kwevalve yokunciphisa i-pneumatic engxamisekileyo yobushushu obuphantsi kuya kuqhubeka nokuphucula, ukubonelela ngenkxaso ethembekileyo yophuhliso loshishino lwegesi yendalo engamanzi.
