Ama-valve ovemvane nama-valve esango ezimo ezihlukene zokusebenza

Ama-valve esango kanyeizivalo uvemvaneemapayipini asetshenziselwa ukudlala indima yokushintsha, ukulawula ukugeleza. Yiqiniso, kusekhona indlela ekukhethweni kwama-butterfly valves nama-valve esango.

Imininingwane efanayo yentengo ye-valve yesango iphakeme kunentengo ye-butterfly valve. Kodwa kusukela ekusetshenzisweni kweminyaka eyishumi edlule, ukwehluleka kwe-valve ye-butterfly kune-valve yesango eliphezulu, ngakho-ke ngaphansi kwezimo zemvume, ukwandisa ukusetshenziswa kwe-valve yesango kufanelekile ukunakwa.

I-Butterfly valve ekusebenziseni umehluko we-valve yesango:

Ngokuhambisana nendima ye-valve yesango kanye ne-valve uvemvane kanye nokusetshenziswa kwe-valve, ukumelana nokugeleza kwe-valve yesango kuncane, ukusebenza kahle kokuvala, ngoba ipuleti le-valve yesango kanye nokugeleza kwemidiya kuyi-engeli eqondile, uma i-valve yesango ekushintsheni kwe-valve ingekho, imidiya ku-valve plate ikhuhla ukuze ipuleti le-valve liqhaqhazele, kulula kakhulu ukukhanyisa ku-valve yesango.

Ipuleti le-Butterfly eliqhutshwa yi-valve stem, uma liphenduka i-90 °, lizokwazi ukuqedela ukuvulwa nokuvala. Shintsha i-engeli yokuchezuka yepuleti uvemvane, ungakwazi ukulawula ukuhamba kwemidiya.

Ukusetshenziswa kwezimo nemidiya: i-butterfly valve ilungele isithando somlilo, igesi, igesi yemvelo, igesi ye-petroleum ewuketshezi, igesi yedolobha, umoya oshisayo nobandayo, ukuncibilika kwamakhemikhali nokukhiqiza amandla nokuvikelwa kwemvelo, ukwakhiwa kwamanzi kanye ne-drainage nezinye izinhlelo zobunjiniyela ukuthutha imidiya ehlukahlukene ebolayo, engagqwali epayipini, esetshenziselwa ukulawula nokunqamula ukugeleza kwemidiya.

I-valve yesangoiyilungu lokuvula nokuvala lesango, isiqondiso sokunyakaza kwesango sibhekene nesiqondiso soketshezi, i-valve yesango ingasetshenziswa kuphela ukuvuleka okugcwele nokuvala okugcwele, akusebenzi kumingcele yomnyango futhi ehlukile. Thuthukisa ubuciko bayo, wenze i-angle yendawo yokuvala lapho kucutshungulwa ukuchezuka, leli sango libizwa ngesango elinwebekayo.

Lapho i-valve yesango ivaliwe, indawo yokubeka uphawu ingathembela kuphela ekucindezelweni okuphakathi ukuze uvale, okungukuthi, ukuthembela kuphela ekucindezelweni okuphakathi kuyoba indawo yokuvala isango ukuya kolunye uhlangothi lwesihlalo ukuze kuqinisekiswe ukuthi indawo yokubeka uphawu yendawo yokubeka uphawu, okuyi-self-sealing. Iningi le-valve yesango lisetshenziselwa ukuphoqelela ukuvalwa, okungukuthi, lapho i-valve ivaliwe, ukuthembela emandleni angaphandle ukuphoqa isango esihlalweni se-valve ukuze kuqinisekiswe ukuthi indawo yokuvala yokuvala uphawu.

Ukunyakaza: isango le-valve yesango elinesiqu se-valve sokunyakaza okuqondile, owaziwa nangokuthii-valve yesango ye-stem ekhuphukayo. I-valve ye-steam nut esangweni, ukuzungezisa kwe-handwheel kushayela ukuzungezisa kwe-valve stem, ukuze isango liphakamise, le valve ibizwa ngokuthi i-valve.i-valve yesango.
