Valve yachipata ili ndi mawonekedwe a kukana kwamadzi ang'onoang'ono, kuthamanga koyenera, kutentha kwamitundu, ndi zina zambiri, ndi imodzi mwama valve odulidwa omwe amagwiritsidwa ntchito kwambiri podula kapena kulumikiza sing'anga mu payipi.Kuchepa kwa m'mimba mwake kumatha kuchepetsa kukula kwa magawo, kuchepetsa mphamvu yofunikira pakutsegula ndi kutseka, ndikukulitsa magwiridwe antchito a magawowo.Komabe, kutayika kwamadzimadzi kumawonjezeka pambuyo pa kuchepa kwa m'mimba mwake.Valve yachipata chotsika kwambiri ku China nthawi zambiri imakhala yopangidwa ndi chitsulo chonyezimira, chomwe nthawi zambiri chimakhala ndi mavuto akulu monga kuzizira kwa thupi komanso kugwa kwa mbale.Tsinde la chitsulo cha carbon of cast iron iron gate valve ndi losavuta kuchita dzimbiri, gasket yonyamula ndi yabwino kwambiri, ndipo kutayikira kwamkati ndi kunja ndikovuta.PN10 low pressure carbon steel gate valve yopangidwa ndi Shanghai Hugong Valve Factory imalowa m'malo mwa valavu yachitsulo yachitsulo, imathetsa bwino mavuto monga chipolopolo cha valavu yachitsulo chachitsulo chosavuta kuzizira ndi kusweka, mbale ya chipata ndi yosavuta kugwa, tsinde la valve ndi losavuta kuchita dzimbiri, ndipo ntchito yosindikiza si yodalirika.

1, kulemera kopepuka: thupi limapangidwa ndi chitsulo chakuda chakuda, cholemera pafupifupi 20% ~ 30% kuposa kulemera kwachipata cha valve, kuyika kosavuta ndi kukonza.

2. Kupaka kwathunthu: chipata chimatenga mphira wapamwamba kwambiri wa rabara wamkati ndi kunja.Ukadaulo waukadaulo waku Europe woyambitsa mphira wa vulcanization umatsimikizira kukula kwake kwa geometric pachipata chovunda, ndipo nkhosa yoponyera mphira ndi ductile ndiyodalirika, sizovuta kugwa komanso kukumbukira bwino zotanuka.

3, chipika chamtundu wathyathyathya: chipata chachikhalidwe nthawi zambiri chimatsuka chubu m'madzi pambuyo pa zinthu zakunja monga mwala, matabwa, simenti, zomangira zachitsulo, zotayira pansi pa valve monga mipata, zosavuta kuyambitsa sizingatseke mwamphamvu. ndi kupanga chodabwitsa chodabwitsa, pansi pa chisindikizo cha zotanuka pampando wapampando mavavu okhala ndi chitoliro chamadzi chokhala ndi mapangidwe athyathyathya, osavuta kupangitsa kuti zinyalala zikhazikike, zipangitsa kuti kuyenda kwake kusakhale kolepheretsa.

4, valavu yoponyera ndalama: thupi la valavu limagwiritsa ntchito kuponyedwa kolondola, kukula kolondola kwa geometric kumapangitsa thupi la valve popanda kutsiriza kutsimikizira kusindikiza kwa valve.
