Kwi-workshop yaseJinbin, kuza kuthunyelwa iqela leevalvu zebhabhathane eziqinileyo ezineemilo ezintathu, ezinobukhulu obuqala kwi-DN65 ukuya kwi-DN400.ivalvu yebhabhathane engaqhelekanga kathathuyivalvu yokuvala esebenza kakhulu. Ngoyilo lwayo olwahlukileyo lolwakhiwo kunye nomgaqo wokusebenza, ibambe indawo ebalulekileyo kwiindawo ezininzi zoshishino. Ulwakhiwo lwayo "lwezinto ezintathu ezingaqhelekanga" yeyona nto iphambili kuyilo:ivalvu yebhabhathane yokutywina eqinileyoI-stem axis iyaphambuka embindini wepleyiti yebhabhathane nakwimbindi womzimba wevalvu, kwaye kwangaxeshanye, umgca ophakathi womphezulu wekhonikhi wokutywina une-engela ethile engaqhelekanga xa kuthelekiswa nomgca ophakathi wombhobho.

Olu lwakhiwo lolwahlulo luphula umthetho wokuhamba kweevalvu zebhabhathane zemveli. Xa ivalvu ivuliwe, ipleyiti yebhabhathane kunye nesihlalo sevalvu ziyaqhawuka ngoko nangoko. Ngexesha lenkqubo yokuvala, ipleyiti yebhabhathane isondela kancinci kancinci kwisihlalo sevalvu, kwaye ekugqibeleni ifikelela ekutywinweni ngokucinezelana kweepawundi zokutywina ze-elastic okanye zesinyithi. Olu lwakhiwo luthintela ngempumelelo ukungqubana phakathi kwepleyiti yebhabhathane kunye nesihlalo sevalvu ngexesha lenkqubo yokuvula nokuvala, lwandisa kakhulu ubomi benkonzo yesibini sokutywina, kwaye kwangaxeshanye kunciphisa i-torque yokusebenza, okwenza ukuvulwa nokuvalwa kwevalvu kube lula kwaye kube lula.

Xa kuthelekiswa nezinye iintlobo zeevalvu, ivalvu yebhabhathane yeSeal Butterfly eqinisiweyo ineengenelo ezibalulekileyo. Okokuqala, inamandla okuvala angcono kakhulu. Isakhiwo sentsimbi esiqiniweyo singafikelela ekungavuzini kwaye simelane noxinzelelo oluphezulu olufikelela kwi-1.6MPa – 10MPa, sihlangabezana neemfuno zeemeko ezahlukeneyo zokusebenza ezinoxinzelelo oluphezulu. Okwesibini, sinokumelana nokugqwala okunamandla nokugqwala. Senziwe ngezinto ezikhethekileyo ze-alloy eqinileyo okanye intsimbi engatyiwayo kwaye sisasebenza ngokuzinzileyo kwiindawo ezinzima ezifana nobushushu obuphezulu, uxinzelelo oluphezulu kunye nokugqwala okunamandla. Okwesithathu, sinobomi obude benkonzo. Ngenxa yokuncipha kokugqwala phakathi kwezinto, ubomi benkonzo yaso bunokufikelela kwiminyaka engaphezu kwe-10 phantsi kweemeko zokusebenza eziqhelekileyo, nto leyo enciphisa kakhulu iindleko zokugcinwa. Okwesine, kulula ukuyisebenzisa kwaye ingaqhutywa ngeendlela ezahlukeneyo ezifana nezandla, umbane kunye ne-pneumatic, ukuhlangabezana neemfuno zolawulo oluzenzekelayo kwiimeko ezahlukeneyo.

Kwimisebenzi ebonakalayo, ivalvu yebhabhathane engavaliyo eqinileyo isetyenziswa kakhulu kumashishini amaninzi. Kwicandelo leekhemikhali zepetroli, isetyenziselwa ukulawula ukuthuthwa kwezinto ezifana nepetroleum, igesi yendalo kunye nezinto ezikrwada zeekhemikhali; Kwishishini lamandla, ukuhamba kwezinto ezifana nomphunga kunye namanzi okupholisa kunokulungiswa ukuqinisekisa ukusebenza okuzinzileyo kwezixhobo zokuvelisa umbane. Kwishishini lesinyithi, iyasebenza kwiinkqubo zemibhobho yezinto ezifana negesi ye-blast furnace, ioksijini, kunye ne-nitrogen. Kwiiprojekthi zokubonelela ngamanzi kunye nokukhupha amanzi, idla ngokusetyenziselwa ukusika kunye nokulawula ukuhamba kwemibhobho kwiinkqubo zokubonelela ngamanzi ezidolophini kunye nonyango lwelindle.

Ngokuphathelele izixhobo ezisebenzayo, ivalvu yebhabhathane engaqhelekanga yaseTshayina ihambelana kakhulu. Ngokuphathelele izixhobo zegesi, ingasetyenziswa kwigesi yendalo, igesi yamalahle, ioksijini, initrogen, umphunga, njl. Ngokuphathelele izixhobo zolwelo, ingasetyenziswa kwipetroliyam, izisombululo zeekhemikhali, amanzi amdaka, amanzi olwandle, njl. Ukongeza, kwezinye izixhobo zokuxuba ezixutyiweyo eziqulethe amasuntswana nothuli, le valve inokubaphatha ngokuzinzileyo, ibonisa ukuzivumelanisa nezimo kakuhle.
