Nyengo ku China tsopano yayamba kuzizira, koma ntchito zopanga za Jinbin Valve Factory zikadali zosangalatsa. Posachedwapa, fakitale yathu yamaliza mndandanda wamaoda azitsulo zofewa za ductilema valve osindikizira, zomwe zapakidwa ndikutumizidwa komwe zikupita.

Mfundo ntchito ductile chitsulo zofewa chisindikizovalavu ya chipata cha wedgezimachokera ku mapangidwe ake apadera ndi zipangizo zomwe zimagwiritsidwa ntchito. Chigawo chapakati cha valve iyi ndi chipata, chomwe chimakulungidwa mu rabara yapadera yonse. Panthawi yogwira ntchito, tsinde la valve limazunguliridwa kuti lisunthire chipata mmwamba ndi pansi, potero kudula kapena kulumikiza madzimadzi mu payipi. Malo awiri osindikizira pachipata nthawi zambiri amapanga mawonekedwe a mphero, ndipo kukula kwa ngodya ya wedge kumasiyana malinga ndi magawo a valve. Chipata chikatsekedwa, zinthu za rabara zimamatira mwamphamvu pampando wa valve chifukwa cha kusinthika kwa elasticity, kukwaniritsa kusindikiza ndi kutulutsa zero.

Kugwiritsa ntchito chitsulo cha ductile kumapereka zinthu zabwino zamakina komanso kukana dzimbiri, pomwe ukadaulo wosindikiza wofewa umatsimikizira kusindikiza komanso moyo wautali wautumiki wa valavu. Komanso, pansi valavu thupi la ductile chitsulo zofewa chisindikizoma valve a chipata cha madzikaŵirikaŵiri amapangidwa ndi pansi lathyathyathya kuti apewe kudzikundikira zinyalala, kuchepetsa kulephera kwa kutsegula ndi kutseka, ndi kuonetsetsa kuti madzi akuyenda bwino. Tsinde la valavu nthawi zambiri limapangidwa ndi zisindikizo zitatu za O-ring kuti achepetse kukana kukangana pakusintha, kuonetsetsa kuti ntchitoyo ikugwira ntchito mosavuta komanso kuti madzi asatayike.

Ntchito zochitika za ductile iron soft sealmavavu a zipata zolimbam'moyo watsiku ndi tsiku zimaphatikizanso izi:

1. Njira yoperekera madzi: Ma valve otsekedwa otsekedwa angagwiritsidwe ntchito m'mapaipi opangira madzi opangira nyumba ndi malonda kuti athetse kusokonezeka ndi kulumikiza kwa madzi, kuonetsetsa chitetezo ndi kudalirika kwa kayendedwe ka madzi.

2. Kuyeretsa zimbudzi: M'mafakitale opangira zimbudzi zam'tawuni ndi ngalande, ma valve otsekedwa ndi zipata zofewa amagwiritsidwa ntchito kuwongolera ndi kuwongolera kutuluka kwa zinyalala, kuteteza kutayikira kwamadzi, komanso kusunga ukhondo wa chilengedwe.

3. Zomangamanga: Pomanga, ma valve otsekedwa otsekedwa amatha kugwiritsidwa ntchito polumikiza ndi kutulutsa mapaipi osakhalitsa, zomwe zimathandiza kuti madzi aziyenda bwino panthawi yomanga.

4. Dongosolo lachitetezo cha moto: Mu makina ozimitsira moto ozimitsira moto, ma valve otsekedwa ndi zipata zofewa amagwiritsidwa ntchito podutsa ndi kuwongolera mawonekedwe papaipi yayikulu kuonetsetsa kuti madzi amoto amaperekedwa panthawi yake.

5. Mthirira waulimi: M'makina othirira m'minda, ma valve otsekedwa ndi zipata zofewa angagwiritsidwe ntchito poyang'anira kayendedwe ka madzi ndi kupititsa patsogolo kagwiritsidwe ntchito ka madzi.

6. Ntchito zamafakitale: Muzinthu zina zamafakitale, monga kukonza chakudya, kupanga mankhwala, ndi zina zotero, ma valve osindikizira a zipata zofewa amagwiritsidwa ntchito pofuna kuwongolera bwino kayendedwe ka madzi, kuonetsetsa kuti zinthu zili bwino komanso chitetezo chopanga.

Ductile iron yofewa yosindikizidwa pachipata cha flange imatha kuwonetsetsa kuti mapaipi amayenda bwino ndikuwongolera chitetezo chaukadaulo, kuwapanga kukhala mtundu wa valve womwe umakonda pamakina owongolera madzimadzi. Ngati muli ndi zofunikira zilizonse, chonde titumizireni pansipa ndipo mudzalandira yankho pasanathe maola 24.
