Kwiworkshop yeJinbin, irhasi eninzi eyenziwe ngokwesikoiivalve zokudambisakuba abathengi sele beqalile ukupakisha kwaye balungele ukuthunyelwa. Ubungakanani buhluka ukusuka kwi-DN405/806/906, kwaye yenziwe nge-carbon steel. I-carbon steel air damper, kunye neempawu zayo "zokunyamezela okuphezulu, ukutywinwa okuqinileyo kunye neendleko eziphantsi", ihlangabezana ngokugqibeleleyo neemeko zokusebenza eziyinkimbinkimbi kunye neemfuno zokulawulwa kweendleko zamashishini okususa imigodi kunye nothuli, kwaye ibe yinto ekhethiweyo yokulawula i-air duct kule meko mibini.

Ngokombono wokunyamezela imeko yokusebenza, kwiinkqubo zokususa imigodi kunye nothuli, iivalve zomoya kufuneka zimelane nokukhukuliseka kwexesha elide lothuli oluphezulu, impembelelo yezinto eziphathekayo kunye nokuguquguquka kwexesha elithile. Isiseko se-carbon steel material ngokwaso sinobunzima obuphezulu kunye nobunzima. Emva kokucima, i-sandblasting okanye i-spraying i-resistant-resistant coatings (efana ne-epoxy resin, i-ceramic particles), ukuxhathisa kwayo kungaphuculwa ngakumbi, ukuchasana ngokufanelekileyo nokugqoka kweengqungquthela ezinzima ezifana nothuli lwe-ore kunye nothuli lwamalahle, kunye nokuphepha ukungaphumeleli kokutywinwa okubangelwa ukuguqulwa kweplati yevalve kunye nesihlalo sevalve ngenxa yokhukuliseko. Okwangoku, i-carbon steel structure inamandla aphezulu kwaye inokumelana nokuguquguquka koxinzelelo lwe-± 5kPa ngaphakathi kwe-air duct. Kwiimeko ezinjengokungena komoya ophantsi komhlaba kunye neenkqubo zokususa uthuli kushishino lwezemigodi, ukutsalwa koxinzelelo olubi akunakufane kwenzeke ukuba kubangele ukuguqulwa kwevalvu yomzimba, ukuqinisekisa uzinzo lwexesha elide lokusebenza.

Ngokubhekiselele ekusebenzeni kokutywinwa kunye nokuhambelana, imboni yokususa uthuli ineemfuno ezingqongqo zokutywinwa kokusebenza kwemibhobho yomoya. Iivalvu zomoya zeCarbon steel, ngokucokiselwa ngokucokisekileyo indawo yokutywina kwaye idityaniswe nerabha enganyangekiyo yeoli okanye iindawo zokutywinwa zerabha ye-fluorine, inokufikelela ukutywinwa okusebenzayo kwaye kuthintele ukunciphisa ukusebenza kakuhle kokususa uthuli ngenxa yokuvuza komoya. Ngaphezu koko, isinyithi sekhabhoni sinokubunjwa ngokudibanisa, okwenza kube lula ukwenza iivalvu zomoya ezinkulu (ezifana ne-2m×1.5m), ezifanelekileyo kwiimfuno zofakelo lweetonela ezinkulu zokungenisa umoya kunye nemibhobho yomoya ephambili yeenkqubo zokususa uthuli kwishishini lemigodi. Ngokwahlukileyo koko, izinto ezifana nentsimbi engatyiwayo ziqhelekile kwi-welding deformation ngexesha lokusetyenzwa komgangatho omkhulu kwaye zineendleko eziphezulu.

Uqoqosho kunye nokugcinwa kwezinto ezibalulekileyo. Ixabiso le-carbon steel raw materials yinye yesithathu kuphela ye-304 yensimbi engenasici. Ukusetyenziswa kwebhetshi kunokunciphisa kakhulu utyalo-mali lokuqala kwiiprojekthi zemigodi kunye nokususa uthuli. Okwangoku, ivalve ye-carbon steel damper inesakhiwo esilula kunye nenxalenye eyomeleleyo yendalo yonke (efana ne-valve shafts kunye ne-actuator interfaces). Kukulungele ukutshintsha iinxalenye ngexesha lokugcinwa kamva ngaphandle kwesidingo sezixhobo ezikhethekileyo. Nokuba kukho umhlwa omncinci kumphezulu, inokulungiswa ngokuqhunyiswa kwesanti ukuze kususwe irusi kunye nokufaka ipeyinti echasene nokuhlwa. Iindleko zokusebenza kunye nokugcinwa kweendleko ziphantsi kakhulu kunezo ze-alloy material flue gas dampers.

I-Jinbin Valve, i-valve eneminyaka engama-20 ubudala eyenza ivalve yomoya, ivelisa kwaye yenza ngokweemfuno zabathengi. Ukuba unayo naziphi na iimfuno ezinxulumeneyo, nceda uqhagamshelane nathi ngezantsi kwaye uya kufumana impendulo kwiiyure ezingama-24!
