Ngokusetyenziswa okubanzi kwegesi yendalo, i-petroleum gas enolwelo kunye namanye amandla kwiindawo zoshishino kunye nezoluntu, indima yobushushu obuphantsi be-pneumatic shutoff valve ekukhuseleni ukhuseleko iya ibaluleka ngakumbi. Kwimeko-bume yobushushu obuphantsi kakhulu, ivalve yokuvala kaxakeka yepneumatic ihlala ingasebenzi kakuhle, ngoko uyilo kunye nokuveliswaubushushu obuphantsi ivelufa yokuvala i-pneumatic engxamisekileyo ujongene nemingeni emininzi. Eli nqaku liza kuphonononga le mingeni kwaye lizise ezinye izisombululo zokuqinisekisa ukusebenza okukhuselekileyo kwiindawo eziphantsi zobushushu.
Okokuqala, ukukhethwa kwezinto eziphathekayo kwindawo yokushisa ephantsi
Kwimeko yokushisa ephantsi, iipropati ezibonakalayo zezinto eziphathekayo ziya kutshintsha, njengamandla, ukuqina, ukuqina, njl., Kuya kuncitshiswa. Ngoko ke, kubaluleke kakhulu ukukhetha izinto ezifanelekileyo kwindawo yokushisa ephantsi. Kwiqondo lobushushu elisezantsi lobushushu bevalufa yokusika i-valufa, eyona mfuno iphambili yokuqwalasela ukukhethwa kwezinto ezifana nomzimba wevalvu, isigqubuthelo sevalvu, isikhondo sevalve kunye nezixhobo zokutywina.
Umzimba we-valve kunye nesivalo se-valve kufuneka simelane nefuthe elidibeneyo loxinzelelo oluphezulu kunye nobushushu obuphantsi, ngoko ke kuyimfuneko ukukhetha izinto ezinamandla amakhulu, ukuqina okuphezulu kunye nokumelana nokushisa okuphantsi, njengensimbi ephantsi yekhabhoni, insimbi engenasici kunye nokunye. I-valve stem kufuneka ibe namandla okwaneleyo kunye nokumelana nokunxiba, ngelixa iqwalasela ukuchaneka kokulungelelaniswa kwayo kunye nomzimba wevalve ukuqinisekisa ukusebenza kokutywinwa kwevalve. Izinto zokutywina kufuneka zibe nokumelana nobushushu obuphantsi kunye nokuzinza kweekhemikhali, njengerabha ye-fluorine, irabha ye-silicone njalo njalo.
2. Iteknoloji yokutywina kwindawo yokushisa ephantsi
Kwimeko yokushisa ephantsi, ukuqina kunye nokuqina kwezinto zokutywinwa kuya kuncitshiswa, okubangelwa ukuhla kokusebenza kokutywinwa. Ngoko ke, kuyilo lwe-valve yokuvala i-valve ephantsi yobushushu obuphantsi, iteknoloji ekhethekileyo yokutywinwa iyafuneka ukuze kuqinisekiswe ukusebenza kokutywinwa.
Ubuchule bokutywina obuqhelekileyo kukusebenzisa isakhiwo sokutywinwa kabini, oko kukuthi, umsesane wokutywina wesinyithi ubekwe phakathi kwesihlalo kunye nesiqu ukwenza itywina eliphindwe kabini. Esi sakhiwo sinokuthintela ngokufanelekileyo ukuvuza kwe-medium kunye nokuphucula ukusebenza kokutywinwa kwevalve. Ukongeza, ukuze kuthintelwe ukuphuka kwesikhondo sevalve kwindawo yobushushu obuphantsi, i-valve stem yokukhusela umkhono kunye nobunye ubuchwepheshe bunokusetyenziswa.
Okwesithathu, inkqubo yokuvelisa phantsi kwendawo yokushisa ephantsi
Kwiqondo lokushisa eliphantsi, iinkqubo eziqhelekileyo zokuvelisa zinokuchaphazeleka, ngoko ke iinkqubo ezikhethekileyo zokuvelisa ziyafuneka. Ngokomzekelo, ekuveliseni i-valve ephantsi yobushushu obuphantsi be-pneumatic yokuvala i-valves, iinkqubo zonyango ze-cryogenic zingasetyenziselwa ukuphucula ukusebenza kobushushu obuphantsi bamacandelo. Ukongezelela, ngexesha lokucutshungulwa kwamacandelo, izixhobo ezikhethekileyo kunye nezixhobo zoomatshini ziyafuneka ukuze kuqinisekiswe ukuchaneka kokucubungula kunye nomgangatho ophezulu.
Uyilo kunye nokuveliswa kwe-valve yokuvala i-valve ephantsi kwe-pneumatic engxamisekileyo ijongene nemingeni emininzi, kodwa nje ukuba amanyathelo asebenzayo athatyathwa ekukhethweni kwezinto eziphathekayo, iteknoloji yokutywinwa, inkqubo yokuvelisa, njl., inokuqinisekisa ukusebenza kwayo kokhuseleko kwindawo yokushisa ephantsi. Kwixesha elizayo, kunye nophuhliso oluqhubekayo lwenzululwazi kunye nobuchwepheshe, kukholelwa ukuba kuya kubakho iteknoloji esebenzayo ngakumbi, kwaye ukusebenza kwe-valve yokusika i-valve ephantsi yobushushu be-pneumatic iya kuba phezulu nangaphezulu.
