Valavu ya chipata ili ndi mawonekedwe a kukana madzi pang'ono, kuthamanga koyenera, kutentha kosiyanasiyana, ndi zina zotero, ndi imodzi mwa valavu yodulidwa yomwe imagwiritsidwa ntchito kwambiri, yomwe imagwiritsidwa ntchito kudula kapena kulumikiza cholumikizira mu payipi. Kuchepa kwa m'mimba mwake kumatha kuchepetsa kukula kwa ziwalozo, kuchepetsa mphamvu yofunikira potsegula ndi kutseka, ndikukulitsa kuchuluka kwa ntchito za ziwalozo. Komabe, kutayika kwa kukana madzi kumawonjezeka pambuyo pa kuchepa kwa m'mimba mwake. Valavu ya chipata yotsika kwambiri ku China nthawi zambiri imapangidwa ndi chitsulo chosungunuka, chomwe nthawi zambiri chimakhala ndi mavuto akulu monga kusweka kwa thupi ndi kugwa kwa mbale ya chipata. Tsinde la chitsulo cha kaboni la valavu ya chipata chachitsulo chosungunuka ndi losavuta kuchita dzimbiri, gasket yolongedza ndi yotsika mtengo, ndipo kutuluka kwamkati ndi kwakunja ndi kwakukulu. Valavu ya chipata chachitsulo cha PN10 yotsika kwambiri yopangidwa ndi Shanghai Hugong Valve Factory imalowa m'malo mwa valavu yachipata chachitsulo, imathetsa mavuto monga chipolopolo cha valavu yachipata chachitsulo chosungunuka ndi chosavuta kuzizira ndi kusweka, mbale yachipata ndi yosavuta kugwa, tsinde la valavu ndi losavuta kuchita dzimbiri, ndipo magwiridwe antchito otseka si odalirika.

1, kulemera kopepuka: thupi lake limapangidwa ndi chitsulo chakuda chapamwamba, kulemera kwake ndi pafupifupi 20% ~ 30% poyerekeza ndi kulemera kwa valavu ya chipata chachikhalidwe, ndikosavuta kukhazikitsa ndi kukonza.

2. Ma CD onse: chipatacho chimagwiritsa ntchito rabara yapamwamba kwambiri ya rabara yonse yamkati ndi yakunja. Ukadaulo wa rabara wa kalasi yoyamba ku Europe umatsimikizira kukula kolondola kwa chipata chopangidwa ndi vulcanized, ndipo rabara ndi ductile casting ram ndizodalirika, sizosavuta kugwa ndipo zimakhala ndi kukumbukira bwino.

3, chitseko cha mabuleki chamtundu wa flat: chipata chachikhalidwe nthawi zambiri chimatsuka chubu m'madzi pambuyo poti zinthu zakunja monga miyala, matabwa, simenti, ma filings achitsulo, madontho osiyanasiyana pansi pa valavu monga mipata, zosavuta kuyambitsa sizingatseke mwamphamvu ndikupanga chodabwitsa chofooka, pansi pa chisindikizo cha mavavu a chipata cha elastic base okhala ndi chitoliro chamadzi chokhala ndi kapangidwe ka flat, chosavuta kuyambitsa zinyalala, zimapangitsa kuti madzi asatseke.

4, thupi la valavu yopangira ndalama: thupi la valavu limagwiritsa ntchito kuponyera kolondola, kukula kolondola kwa geometric kumapangitsa thupi la valavu popanda kumaliza chilichonse kutsimikizira kutsekedwa kwa valavu.
