Kuyendera ma valve

Zofunikira zoyenera za khalidwe la valve zakhazikitsidwapatsogolomu miyezo.

①The mankhwala chigawo ndimakina katunduzida zazikulu za valavu zimagwirizana ndi zofunikira pamiyezo yoyenera.

②Kulakwitsa kwa mawonekedwe ndi kukula kwa valvezoponyakwaniritsani malamulo pazojambula.

II.Njira Yoyesera ndi Kuyendera

Thezoponyamawonekedwe ndi kukula zigwirizane ndichofunikawa zojambula luso ndi malamulo kuchokerawofuna.Theosacheperamakulidwe a khoma la magawo a valve, cholakwika cha kutalika kwa kapangidwe,kusamuka kwa abrasionchilolezo chambale pachipatasichidzatsika kuposa zomwe zimafunikira mulingo waukadaulo wamankhwala ndi zojambula zazinthu.Pamwamba pa akhakulavalavundi chipolopolo choponderezedwa cha chinthu chomaliza cha valve sichidzakhala ming'alu,ozizira kutseka, kuphatikiza mchenga, pore ndi zolakwika zina.The kumamatira mchenga, sprue, chokwerandioxide khungupamwamba pa castings ayenera kutsukidwa.

2,KupanikizikaYesani

Mayesero amphamvu kwambirimazikokuyesa kwa valve.Evalve iliyonse iyenera kuchitidwa kuti iyesedwe kupanikizika musanaperekedwe ku fakitale.Tamayesa kuthamanga ndi nthawi yanthawi kumatsatira malamulowoGB/T13927, ndi zinthu zoyesera zimaphimba mayeso a chipolopolo ndi mayeso osindikiza.Ngati aliyense wakumbuyoKusindikiza pa valve, kumafunika kuchitamayeso a chisindikizo chakumbuyo. Dkuyesa njira yoyesera, ndimphamvu yakunjazomwe zingakhudze zotsatira zoyesa sizingagwiritsidwe ntchito pa valve.Kupanikizika kwa mayeso kumakhala kosalekeza panthawi ya kukakamiza kugwirana ndi kuyesa.

Kuyesa kwa chipolopolo kwa valavu ndi mtundu wa kuyesa kukakamiza kwa chipolopolo chonse cha valve cholumikizidwa ndi thupi la valve ndi chivundikiro.Cholinga chake ndikuwunikacompactnesspakati pa thupi la valve ndi chophimba, chomwe ndi anti-kupanikizikamphamvu ya chipolopolo chonse kuphatikizapo kugwirizana kwa thupi la valve ndi chivundikiro.

Thekusindikiza mayeso ndi kufufuza ntchito yambali zotulukandi valvekusindikiza awiri, ndipo akhoza kugawidwa mu high-pressure liquid sealing test and low-pressure air kusindikiza test.
