Puv -bore valvesmuaj ib txoj kab uas hla sab hauv uas yog qhov tseem ceeb zoo ib yam li cov yeeb nkab txoj kab uas hla, uas ua rau cov dej ntws tsawg kawg nkaus thiab ua rau lawv haum rau siab - ntws- tus nqi thauj mus los thiab cov kav dej huv. Kev txo qis -dhau li qub, ntawm qhov tod tes, muaj ib txoj kab uas hla me dua li cov yeeb nkab sab hauv txoj kab uas hla, ua rau me me thiab tus nqi qis dua, ua rau lawv haum rau cov kev siv niaj hnub nrog cov kev xav tau qis dua.
Puv -bore valves(xws li tag nrho- pob valves) ntiav ib qho tas li - dav ntws channel tsim, qhov twg txoj kab uas hla ntawm sab hauv los ntawm - qhov yog kwv yees sib npaug rau lub npe kab ntawm cov yeeb nkab txuas (feem ntau ntau dua 95% ntawm qhov chaw nres nkoj sab hauv). Piv txwv li, DN50 puv -bore valve muaj qhov ntws channel txoj kab uas hla ze li 50mm. Qhov kev tsim no tso cai rau cov kua dej yuav luag tsis muaj kev cuam tshuam, kev poob siab tsawg, thiab muaj peev xwm ntws mus txog ntawm cov yeeb nkab ncaj, ua rau lawv tshwj xeeb tshaj yog tsim rau cov tshuab uas xav tau kev thauj mus los zoo lossis kev tu lub sijhawm.
Piv txwv li,txo -bore valvesmuaj qhov tseeb ntws channel txoj kab uas hla ib los yog ntau qhov me me dua li lawv cov nominal txoj kab uas hla. Piv txwv li, ib tug DN50 txo- pob valve muaj ib tug khiav channel txoj kab uas hla ntawm kwv yees li 38 hli, roughly sib npaug rau ib tug loj DN40. Thaum qhov no "txo- bore" tsim me ntsis nce ndlwg tsis kam, nws txo qhov loj thiab qhov hnyav, txuag qhov chaw thiab txo qis kev teeb tsa.

FAQ
Dab tsi yog lub pob valve tag nrho?
Ib qhov chaw nres nkoj puv lossis qee zaum hu ua tag nrho bore, pob valvemuaj txoj hauv kev ncaj nraim uas tsis muaj qhov txo qis thaum nws mus los ntawm lub valve.
Dab tsi yog qhov txo qhov chaw nres nkoj pob valve?
Qhov txo -port pob valve, tseem hu ua tus qauv-port pob valve lossis txo- pob valve, yogib hom valve feem ntau siv los tswj cov dej ntws los ntawm cov kav dej thiab tubing.
