FAQ
Q: Dab tsi yog qhov Underground Non -Rising Stem Gate Valve?
A: Nws yog subterranean kev rho tawm valve qhov twg qia tig mus rau sab hauv yam tsis tau nce vertically. Txuas mus rau lub qia txuas ntxiv, nws tso cai rau tag nrho cov dej tswj ncaj qha los ntawm theem hauv av.
Q: Cov valve no puas tuaj yeem muab faus ncaj qha rau hauv av yam tsis muaj chav ua vaj tse?
A: Yog, nruab nrog fusion-cov txheej txheem epoxy, cov khoom siv stainless hlau, thiab cov khoom siv ncaj qha - faus ntxiv, nws tuaj yeem muab faus ncaj qha rau hauv cov av rov qab.
Q: Yuav ua li cas cov neeg teb xov tooj qhib thiab kaw lub faus valve?
A: Ib qho txuas txuas txuas txuas txuas lub valve mus rau hauv av-theem txoj kev lub thawv, tso cai rau cov neeg ua haujlwm tig lub tshuab siv tus qauv T- tuav tus yuam sij los ntawm qhov av saum toj no.
Q: Dab tsi yog qhov txawv ntawm qhov nce thiab tsis yog - nce qia tsim?
A: Rising qia li qub txuas ntxiv mus thaum lawv qhib, xav tau qhov chaw ntsug ntau heev. Tsis yog- nce qia li qub tuav qhov siab ruaj khov, ua rau lawv zoo tagnrho rau faus lossis qis - tshem tawm kev teeb tsa.
Q: Lub valve no puas tuaj yeem siv rau kev kaw lossis tswj cov dej ntws?
A: Tsis yog, rooj vag li qub yog tsim tshwj xeeb rau kev qhib siab lossis kaw tag nrho. Kev khiav hauj lwm nyob rau hauv ib feem qhib txoj hauj lwm ua rau turbulence thiab puas elastomeric wedge.
Q: Cov lus qhia dab tsi uas xav tau los thov kom ceev cov lus hais?
A: Muab cov yeeb nkab nominal loj, ua haujlwm siab (PN ntsuam xyuas lossis Chav Kawm), flange drilling txuj, faus qhov tob, hom xov xwm, thiab cov txheej txheem tshwj xeeb lossis cov khoom nyiam.
