Txoj Cai Ua Haujlwm
Lub valve tswj cov kab ntws los ntawm txoj kab ntsug ntawm cov kab uas muaj zog:
Qhib
Tig lub handwheel counterclockwise tsa lub qia thiab wedge kom meej ntawm qhov ntws, ua kom tag nrho cov kua tshaj tawm nrog kev sib txhuam tsawg.
Kaw
Tig clockwise txo tus qia, tsav lub npoo mus rau hauv qhov chaw zaum.
Kev sib khi
Lub elastic wedge compresses tawm tsam lub cev sab hauv, ua npuas -tight bi-directional seal.

FAQ
Q: Dab tsi yog qhov resilient seated nce qia rooj vag valve?
A: Nws yog lub raj xa dej cais tawm nrog cov roj hmab -coated wedge thiab lub qia sab nraud uas txav vertically thaum lub valve qhib los yog kaw, muab lub kaw ntom ntom hydraulic thiab ncaj qha saib xyuas txoj haujlwm.
Q: Thaum twg kuv yuav tsum qhia kom meej qhov nce qia rooj vag valve hloov NRS valve?
A: Xaiv qhov nce qia valve rau kev teeb pom kev zoo xws li chav twj tso kua mis lossis cov nroj tsuag dej uas xav tau kev kuaj pom qhov pom thiab qhov kev tshem tawm ntsug muaj.
Q: Cov li qub no puas tau tso cai rau cov kav dej?
A: Yog. Cov li qub ua nrog tsis yog- tshuaj lom EPDM elastomer wedges thiab fusion- cov txheej txheem epoxy ua tau raws li cov dej haus huv thoob ntiaj teb.
Q: Lub rooj vag valve no puas tuaj yeem siv los ua cov kab ntws?
A: Tsis yog. Lub rooj vag li qub yog tsim los nruj heev rau tag nrho - qhib lossis tag nrho - kaw kev cais. Kev khiav hauj lwm nyob rau hauv ib nrab txoj hauj lwm ua rau kev co thiab ua ntej lub sij hawm wedge hnav.
Q: Cov ntsiab lus dab tsi xav tau rau kev hais lus raug?
A: Thov qhia qhov loj me, qhov ntsuas siab, tus qauv flange, lub cev thiab cov khoom siv qia, ua haujlwm nruab nrab, qhov kub thiab txias, thiab xav tau kom muaj nuj nqis.
