Izinkambu zebhathela zisetshenziswa ekuzikhandla

Izinkuni zezinyoni ziyadinga emikhakheni

　　1. Butterfly valve is suitable for flow regulation. As the pressure loss of butterfly valve in the pipeline is relatively large, about three times as much as that of the gate valve, so when choosing butterfly valve, the pipeline system should be fully considered by the pressure loss, and should also be considered to close the butterfly plate to withstand the pressure of the pipeline medium firmness. In addition, must also be considered in the high temperature of the elastic valve seat material to withstand the limitations of the operating temperature.

Indzawo yokwenza isiphetho esincane kanye nokukhulu kwesisekelo somqulu we-butterfly valve kuyinto encane, isisindo esinendawo, kusukela kakhulu kuya ekuphakameni, futhi inamathuba amaningi okukhulisa umoya, isizinda somqulu we-butterfly valve Z kuyinto ekwakhiweni izindlela ezinkulu zezivalo. Uma kudinga umqulu we-butterfly valve ukuthi kwenziwe ukukhulisa umoya, kungenzeka ukhetha isayizi esisiza kanye nesiqephu somqulu we-butterfly valve ukuze kube nokusebenza kahle nokwenzeka.

Kukhona okuningi, ekugcineni, ekubhekisela nokuphatha ngesimo semudi, kudinga ukuthi isakhiwe kube semfutshane kanye nokukhanya ekuboniseni nokufaka (1/4r). Ukucutshungulwa okuncane (isiphetho esincane), isiqondiso esithandwayo sokukhetha i-valve ye-butterfly.

Eminye imininingwane yokugcina, indawo esheshayo, isikhwama esincane, ukuphazamisa nokuphazamisa, isilinganiso esincane sokuphazamisa kwi umoya, ngezindlela zokwenza, ungakhethe i-valve yebhathifela.

Eminye imizuzu yokugcina yokugcina, okanye ukufuna ukugcina okuqinileyo, okanye ukugqoka nokugqoka, okugcwele (okukhula okukhulu) kanye nokunye okwenziwa kwezinkomba zebhatheli, kudinga ukusebenzisa izinto ezithandwayo ezithandwayo zebhatheli ezinamandla nezithandwa, izinto ezintathu ezithandwayo noma ezimbili ezithandwayo zebhatheli.

Izinkomba zebhathela zezinkomba zikwazi ukwenzela izinto ezithile njengezilwane ezintsha, amanzi amhlophe, amanzi amanzi, amanzi amanzi, isithutha, umoya omusha, ukudla, umuthi, amafutha kanye nezinye izinto ezifuna ukuphendula okuphelele, ukungatholakali kwamagazini, izidingo zeminyaka engaphezu kwe-10, kanye nezimo zokusebenza ezifana ne-150℃.

7. I-ivalvu ye-butterfly ye-eccentric seal ye-soft iyathokozisa ukufinyelela nokufaka okwesibili nokuphakamisa kwepayipi yokuphefumula nokucima, ikhona ekwenziwe kakhulu emetallurgy, ekusebenzeni okulula, i-elekthriki, i-petrochemical system yepayipi yegasi kanye nezindlela zokuphakama.
