Posachedwapa, ma valve awiri osindikizira a zipata zazikulu zofewa ndi kukula kwa DN700 anatumizidwa bwino kuchokera ku fakitale yathu ya valve. Monga fakitale yaku China yopangira ma valve, kutumiza bwino kwa Jinbin kwa valavu yayikulu yofewa yosindikizira kukuwonetsanso luso lapadera la fakitale posintha mavavu.

Chifukwa chiyani musankhe vavu yachipata chofewa chokhala ndi mainchesi akulu?

Choyamba,valavu yotsekera pachipatakukhala ndi maubwino osindikiza bwino komanso magwiridwe antchito osavuta, pomwe kapangidwe kake ka mainchesi kakang'ono kamakwaniritsa zofunikira zaukadaulo pakuwongolera kuthamanga kwambiri. M'makina operekera madzi am'tawuni ndi ngalande, mavavu otsekedwa ndi mainchesi ofewa amatha kuyendetsa bwino madzi, kuwonetsetsa kuti madzi azikhala okhazikika komanso ngalande zosalala. M'mafakitale otsuka zimbudzi, amatha kuwongolera modalirika kayendedwe ka zinyalala ndikupereka chithandizo champhamvu pakuwongolera zimbudzi. M'mapulojekiti akuluakulu a mafakitale monga mafakitale a mankhwala ndi magetsi, izivalavu ya chipata cha flangedimathanso kutenga gawo lofunikira pakuwongolera bwino kwazinthu zosiyanasiyana.

Chisindikizo chofewa cha DN700 chachikulu m'mimba mwakemtengo wa valve gatekutumizidwa nthawi ino kwayesedwa kokhazikika komanso kupangidwa kolondola ndi fakitale, kuwonetsetsa kudalirika kwake komanso kukhazikika pakagwiritsidwe ntchito.

Fakitale yathu nthawi zonse yakhala ikudzipereka kuti ipatse makasitomala ntchito zamtundu wapamwamba kwambiri. Kuchokera pakupanga mpaka kupanga, sitepe iliyonse imayendetsedwa mosamalitsa kuti ikwaniritse zosowa za makasitomala osiyanasiyana. Ndi zida zopangira zotsogola, gulu laukadaulo laukadaulo, komanso kasamalidwe kolimba kabwino, tadziwika ndi makasitomala ambiri.

Kutumizidwa kwa ma valve akuluakulu otsekemera otsekemera otsekemera otsekemera nthawi ino sikuti ndi phindu lofunika la fakitale, komanso amapereka chithandizo champhamvu pa chitukuko cha mafakitale okhudzana nawo. Ndikukhulupirira kuti m'tsogolomu, monga wopanga ma valve a pachipata cha China, Jinbin adzapitirizabe kuyendetsedwa ndi luso komanso khalidwe labwino, kupatsa makasitomala zinthu zambiri zamtengo wapatali za valve ndikuthandizira nyonga yayikulu pakukula kwa mafakitale opanga ma valve.
