Eshabhu laseJinbin, igesi eminingana eyenziwe ngokwezifisoamavalvu okunciphisangoba amakhasimende aseqalile ukupakisha futhi aselungele ukuthunyelwa. Usayizi uyahluka kusukela ku-DN405/806/906, futhi wenziwe ngensimbi yekhabhoni. I-carbon steel damper yomoya, enezici zayo "zokubekezelela okuphezulu, ukuvala okuqinile kanye nezindleko eziphansi", ihlangabezana kahle nezimo zokusebenza eziyinkimbinkimbi kanye nezidingo zokulawula izindleko zezimboni zezimayini nokususa uthuli, futhi isibe yisinqumo esiyinhloko sokulawula imibhobho yomoya kulezi zimo ezimbili.

Ngokombono wokubekezelela isimo sokusebenza, ezinhlelweni zokumba nokususa uthuli, ama-valve omoya adinga ukumelana nokuguguleka kwesikhathi eside kothuli olunezinga eliphezulu, umthelela wezinto kanye nokushintshashintsha kwengcindezi ngezikhathi ezithile. Izinto eziyisisekelo zensimbi yekhabhoni ngokwazo zinokuqina okuphezulu nobunzima. Ngemva kokucima, ukuqhumisa isihlabathi noma ukufafaza izembozo ezingagugi (njenge-epoxy resin, izinhlayiya ze-ceramic), ukumelana kwayo nokuguguleka kungathuthukiswa kakhulu, kumelane ngempumelelo nokuguguleka kwezinhlayiya eziqinile njengothuli lwe-ore kanye nothuli lwamalahle, futhi kugwenywe ukwehluleka kokuvala okubangelwa ukuguquka kwepuleti le-valve kanye nesihlalo se-valve ngenxa yokuguguleka. Okwamanje, isakhiwo sensimbi yekhabhoni sinamandla aphezulu futhi singamelana nokushintshashintsha kwengcindezi kwe-±5kPa ngaphakathi kwepayipi lomoya. Ezimweni ezifana nohlelo lokungenisa umoya ngaphansi komhlaba kanye nokususwa kothuli embonini yezimayini, ukukhishwa kwengcindezi okungekuhle cishe akubanga ukuguguleka komzimba we-valve, okuqinisekisa ukuzinza kokusebenza kwesikhathi eside.

Ngokuphathelene nokusebenza kokuvala kanye nokuhambisana, imboni yokususa uthuli inezidingo eziqinile zokusebenza kokuvala imibhobho yomoya. Amavalvu omoya ensimbi yekhabhoni, ngokusebenzisa izindawo zokuvala ezicutshungulwe kahle futhi kuhlanganiswe nezingxenye zokuvala zerabha noma irabha ye-fluorine engangeni uwoyela, angafinyelela ukuvala okusebenzayo futhi agweme ukunciphisa ukusebenza kahle kokususa uthuli ngenxa yokuvuza komoya. Ngaphezu kwalokho, insimbi yekhabhoni ingakhiwa ngokushisela, okwenza kube lula ukukhiqiza amavalvu omoya amakhulu (njenge-2m×1.5m), afanele izidingo zokufakwa kwemigudu emikhulu yokungenisa umoya kanye nemibhobho yomoya eyinhloko yezinhlelo zokususa uthuli embonini yezimayini. Ngokuphambene nalokho, izinto ezifana nensimbi engagqwali zivame ukuguqulwa ukushisela ngesikhathi sokucubungula okukhulu futhi zinezindleko eziphakeme.

Umnotho kanye nokugcinwa kahle yizinzuzo ezibalulekile. Intengo yezinto zokusetshenziswa zensimbi yekhabhoni iyingxenye eyodwa kwezintathu kuphela yensimbi engagqwali engu-304. Ukusetshenziswa kwe-batch kunganciphisa kakhulu ukutshalwa kwezimali kokuqala kumaphrojekthi okumba kanye nokususa uthuli. Okwamanje, i-valve ye-carbon steel damper inesakhiwo esilula kanye nobubanzi bezingxenye eziqinile (njenge-valve shafts kanye ne-actuator interfaces). Kulula ukufaka ezinye izingxenye esikhundleni sazo ngesikhathi sokulungiswa kamuva ngaphandle kwesidingo samathuluzi akhethekile. Ngisho noma kukhona ukugqwala okuncane ebusweni, kungalungiswa ngokuqhumisa isihlabathi ukuze kususwe ukugqwala nokusebenzisa upende wokulwa nokugqwala. Izindleko zokusebenza nokulungisa ziphansi kakhulu kuneze-alloy material flue gas dampers.

I-Jinbin Valve, umenzi wamavalvu omoya odambisa umoya we-valve oneminyaka engu-20 ubudala, ukhiqiza futhi akhiqize ngokwezidingo zamakhasimende. Uma unezidingo ezihlobene, sicela usithinte ngezansi futhi uzothola impendulo zingakapheli amahora angu-24!
