Eshabhu lakwaJinbin, kunegesi eminingana eyenziwe ngokwezifisoama-damper valvesngoba amakhasimende aseqalile ukupakisha futhi alungele ukuthunyelwa. Usayizi uyahluka kusuka ku-DN405/806/906, futhi yenziwe nge-carbon steel. I-carbon steel air damper, enezici zayo "zokubekezelelana okuphezulu, ukubeka uphawu okuqinile kanye nezindleko eziphansi", ihlangabezana ngokuphelele nezimo eziyinkimbinkimbi zokusebenza kanye nezidingo zokulawula izindleko zezimboni zokumba kanye nokukhipha uthuli, futhi isibe yisinqumo esivamile sokulawula imigudu yomoya kulezi zimo ezimbili.

Ngokombono wokubekezelela isimo sokusebenza, ezinhlelweni zokususa izimayini nothuli, amavalvu omoya adinga ukumelana nokuguguleka kwesikhathi eside kothuli olugxilile, umthelela wezinto ezibonakalayo kanye nokuguquguquka kwengcindezi ngezikhathi ezithile. I-carbon steel base material ngokwayo inokuqina okuphezulu nobulukhuni. Ngemva kokucisha, ukuqhunyiswa kwe-sandblasting noma ukufafaza izigqoko ezingagugi (njenge-epoxy resin, izinhlayiya ze-ceramic), ukumelana kwayo nokugqoka kungathuthukiswa ngokuqhubekayo, ukumelana ngokuphumelelayo nokuguga kwezinhlayiya eziqinile ezifana nothuli lwe-ore nothuli lwamalahle, nokugwema ukwehluleka kokuvala okubangelwa ukuguqulwa kwepuleti le-valve nesihlalo se-valve ngenxa yokuguguleka. Ngaleso sikhathi, isakhiwo se-carbon steel sinamandla aphezulu futhi singamelana nokuguquguquka kwengcindezi ye-±5kPa ngaphakathi kwepayipi lomoya. Ezimeni ezinjengokungena komoya ongaphansi komhlaba kanye nezinhlelo zokususa uthuli embonini yezimayini, ukukhishwa kwengcindezi engemihle mancane amathuba okuba kubangele ukuguquguquka komzimba wama-valve, okuqinisekisa ukuzinza kwesikhathi eside.

Mayelana nokusebenza kokuvala nokuhambisana, imboni yokususa uthuli inezidingo eziqinile zokuvala ukusebenza kwamapayipi omoya. Amavalvu omoya ensimbi ekhabhoni, ngokusebenzisa izindawo zokuvala ezicutshungulwe kahle futhi ezihlanganiswe nenjoloba engamelana nowoyela noma izingxenye zokuvala zenjoloba e-fluorine, angafinyelela ukuvalwa kahle futhi agweme ukwehlisa ukusebenza kahle kokukhipha uthuli ngenxa yokuvuza komoya. Ngaphezu kwalokho, i-carbon steel ingakhiwa ngokushisela, okwenza kube lula ukwenza ama-valve omoya amakhulu (afana no-2m×1.5m), afanele izidingo zokufakwa kwemigudu emikhulu yokungenisa umoya kanye nemigudu yomoya eyinhloko yezinhlelo zokususa uthuli embonini yezimayini. Ngokuphambene, izinto ezifana nensimbi engagqwali zithambekele ekuwohlokeni kokushisela ngesikhathi sokucubungula okukhulu futhi zinezindleko eziphakeme.

Umnotho kanye nokugcinwa kukhona izinzuzo ezibalulekile. Intengo yezinto ezibonakalayo ze-carbon steel iyingxenye eyodwa kwezintathu kuphela yaleyo ka-304 yensimbi engagqwali. Ukusetshenziswa kweqoqo kunganciphisa kakhulu ukutshalwa kwezimali kokuqala kumaphrojekthi wezimayini nokususa uthuli. Khonamanjalo, i-carbon steel damper valve inesakhiwo esilula kanye nengxenye eqinile yendawo yonke (njengama-valve shafts kanye ne-actuator interfaces). Kuhle ukushintsha izingxenye ngesikhathi sokulungiswa kamuva ngaphandle kwesidingo samathuluzi akhethekile. Ngisho noma kunokugqwala okuncane phezulu, kungalungiswa ngokuqhunyiswa kwesanti ukuze kukhishwe ukugqwala nokusebenzisa upende ovimbela ukugqwala. Izindleko zokusebenza nezokulungisa ziphansi kakhulu kunezidambisisi manzi ze-alloy material flue.

I-Jinbin Valve, i-valve eneminyaka engu-20 ubudala ekhiqiza ama-valve e-damper air, ikhiqiza futhi ikhiqize ngokuvumelana nezidingo zamakhasimende. Uma unezinye izidingo ezihlobene, sicela usithinte ngezansi futhi uzothola impendulo kungakapheli amahora angama-24!
