Mu malo ochitira masewera a Jinbin, gulu lina la mavavu a chipata chofewa chotsekedwa ndi flange ndi okonzeka kutumizidwa, kuphatikizapo tsinde lobisikavalavu yofewa yotsekedwa ndi chipata cha flangendi valavu yowonekera ya chipata cha flange, yokhala ndi kukula kwa DN80 ndi DN100, ndipo yopangidwa ndi chitsulo chosungunuka QT450. Monga ogwira ntchito yokonza mapaipi, kusankha valavu yoyenera yotsekedwa bwino ya chipata sikungochotsa zoopsa zotuluka komanso kukulitsa nthawi yogwira ntchito ndikuchepetsa ndalama zogwirira ntchito ndi kukonza. Mukagula, palibe chifukwa choyerekeza mitengo mosasamala. Yang'anani mfundo zazikulu: kufananiza mikhalidwe yogwirira ntchito, zipangizo zapamwamba, njira zopangidwira, ndi ntchito yodalirika yogulitsa pambuyo pogulitsa. Musatsatire mitengo yotsika mosasamala. Pokhapokha mutayesa bwino khalidwe ndi magwiridwe antchito amtengo wapatali ndi pomwe mungasankhe valavu yodalirika komanso yolimba ya chipata.

(chithunzi: Valavu ya Chipata Chosatseka Chosakwera cha Flange Dn100, Valavu ya Chipata Chosatseka Chosakwera cha Flange Dn80) 

Choyamba, gwirizanitsani ndi momwe zinthu zilili pa ntchito. Yang'anani patsogolo kuthamanga kwa chitoliro ndi m'mimba mwake. Pazinthu zonse zoperekera madzi ndi ngalande komanso zotetezera moto, 1.0/1.6 MPa nthawi zambiri imakhala yokwanira. Komabe, pazochitika zotentha kwambiri komanso zopanikizika kwambiri, mulingo wokana kuthamanga uyenera kukwezedwa. Nthawi yomweyo, dziwani bwino mtundu wa cholumikizira. Zipangizo zosiyanasiyana zotsekera ndizoyenera madzi oyera ndi zinyalala kuti zinthu zisawonongeke komanso kuti zisakule msanga. 

Kachiwiri, samalani ndi mtundu wa thupi la valavu ndi chisindikizo.valavu ya chipata cha madziThupi liyenera kupangidwa ndi chitsulo cholimba, chomwe ndi champhamvu komanso cholimba kuti chisawonongeke. Pewani kutayidwa ndi zipolopolo zopyapyala. Chisindikizo chofewa ndiye chimake. Ndikofunikira kusankha zigawo zomatira za EPDM kapena NBR, zomwe zimakhala ndi kusinthasintha kwabwino komanso magwiridwe antchito olimba omatira, sizingatulutse madzi, komanso sizingatulutse madzi, komanso sizingatulutse madzi, kutuluka madzi, kapena kutuluka madzi.

Komanso, samalani ndi kapangidwe kake ndi luso lake. Sankhani kapangidwe ka tsinde lobisika, lomwe limatenga malo ochepa ndipo silingathe kusonkhanitsa fumbi ndi dzimbiri. Mbali ya flange iyenera kukhala yathyathyathya komanso yopanda zilema, yokhala ndi mabowo olunjika bwino kuti muyike mosavuta komanso kulumikizana pamalopo. Tsinde la valavu yotsekera liyenera kukhala losalala popanda kumamatira, zomwe zimalola kutsegula ndi kutseka mosavuta, ndipo siliyenera kumamatira ngakhale mutagwiritsa ntchito kwa nthawi yayitali.

Pomaliza, samalani ndi ziyeneretso ndi ntchito yogulitsa pambuyo pogulitsa. Funsani malipoti ndi satifiketi yowunikira, ndipo perekani zinthu popanda chidziwitso chilichonse. Ikani patsogolo opanga omwe ali ndi ntchito yonse yogulitsa pambuyo pogulitsa, chitsimikizo chomveka bwino cha khalidwe, ndi mayankho achangu. Mavuto aliwonse mtsogolo angathe kuthetsedwa mwachangu. Jinbin Valve yakhala ikupanga ma valve apamwamba kwa zaka 20 (Wopanga Ma valve a Chipata), ndipo ali ndi chitsimikizo cha khalidwe. Ngati muli ndi zosowa zina zokhudzana ndi izi, chonde titumizireni uthenga pansipa. Mudzalandira yankho mkati mwa maola 24!
