Valve Yachipata Cha Hard Seal

Ndife akatswiri opanga ma valve omwe ali ndi ziphaso za ISO, CE ndi API. Tili ndi zida zopangira zapamwamba komanso gulu lonse la machitidwe owongolera. Timavomerezanso maoda a OEM ndi ODM, okhala ndi madongosolo ochepa osinthika. Ma valve athu olimba olimba osindikizira amatumizidwa padziko lonse lapansi ndipo amazindikiridwa ndi makasitomala aku mafakitale.

Makhalidwe Ofunika

Kodi pali kusiyana kotani pakati pa chosindikizira chachitsulo cholimba ndi mavavu a zipata zofewa?

Mavavu osindikizira olimba amatchinga madzimadzi ndi zitsulo zogwira ntchito; ma wedges awo ndi mipando yawo yokutidwa ndi Stellite alloy. Mitundu yofewa yosindikizira imagwiritsa ntchito mphira kapena PTFE zofewa kuti zisindikize. Zisindikizo zolimba zimatha kuthana ndi kutentha kwakukulu komanso kupanikizika kwambiri, koma zingwe zofewa zimatha kupindika kapena kusweka pakutentha kwambiri. Ma valve osindikizira ofewa amasindikiza bwino kwambiri pakutentha koyenera, ngakhale mbali zake zofewa zamkati zimavala mwachangu pomwe zotengera zotentha zimadutsa. Malo osindikizira olimba sagwira kukandwa koma amafuna makina olondola kwambiri panthawi yopanga.

Ndi mapaipi amtundu wanji omwe amagwira ntchito amadalira mavavu osindikizira olimba?

Ma valve awa amakwanira mizere yonyamulira nthunzi yotentha kwambiri, mafuta otentha, gasi woponderezedwa ndi mpweya wotentha wa flue. Madera omwe amagwiritsidwa ntchito kawirikawiri amakhala ndi malo opangira magetsi otenthetsera, malo opangira mafuta a petrochemical, mafakitale azitsulo ndi makina otenthetsera moto.

Kodi mavavu a zipata zachitsulo zolimba zosindikizira ali ndi mphamvu ziti?

Amagwira ntchito mokhazikika pansi pa kutentha kwakukulu ndi kupanikizika, mikhalidwe yomwe ma valve osindikizira ofewa sangathe kupirira. Chophimba chachitsulo cha Stellite chimayimilira bwino kuti chikhale chothamanga, chosokoneza, kotero valavu imakhala nthawi yaitali. Kubowola kwake kowongoka kwathunthu kumalepheretsa kutuluka kwa madzimadzi, abwino kwa mapaipi omwe amangotseguka kapena kuzimitsa kwathunthu. Imakwaniritsanso miyezo ya chitetezo cha moto kwa malo ogulitsa mafakitale.

Ndi zovuta ziti zomwe ma valve osindikizira getilo ali ndi?

Kuwapanga kumafunikira ntchito yabwino yopangira makina, motero amawononga ndalama zambiri kuposa zosindikizira zofewa. Pakutentha kwanthawi zonse, sangathe kusindikiza ngati mavavu ofewa osindikizira. Kutsegula ndi kutseka kosalekeza kumatchinga zitsulo zosindikizira zimayang'ana pang'onopang'ono, ndipo kusindikiza kumaipiraipira pakagwiritsidwa ntchito zaka zambiri. Amakhalanso olemera komanso ochulukirapo kuposa ma valve osindikizira ofewa amtundu wofanana.
