Ntsiab nta
Peb tsim lub viav vias hom tsis rov qab nrog cov roj hmab-coated viav vias nrov plig plawg. Cov roj hmab hnyav hnyav npog tag nrho cov flap nto. Thaum kaw, roj hmab nias nruj tiv thaiv lub ntsej muag. Rov qab-flow seepage nyob twj ywm tsawg, thiab kaw-off kev ua tau zoo tuav ruaj khov rau cov dej num hauv ntiaj teb tiag.
Ductile hlau tsim cov vaj tsev loj. Ob sab hauv thiab sab nrauv tau txais epoxy-hmoov los tiv thaiv corrosion. Roj hmab-coated viav vias nrov plig plawg tuaj yeem sawv kev laus, acid thiab alkali nres. Nrog rau cov khoom siv zoo li no, tag nrho chav tsev muab kev ua haujlwm ntev.
Flange qhov ntev ua raws li PN10 thiab PN16 cov qauv. Cov neeg yuav khoom tuaj yeem txuas ncaj qha rau cov kav hlau kav hlau, cov kav hlau steel, ntxiv rau PE-cov yeeb nkab ntsig txog fittings. Tsis muaj qhov hloov pauv ntxiv uas xav tau rau kev sib piv.
Nws sab hauv layout nyob twj ywm haum yooj yim. Muaj ob peb qhov txav mus rau hauv, tsis muaj qhov nyuaj caij nplooj ntoos hlav sib dhos built-in. Field-side hloov rau viav vias nrov plig plawg tuaj yeem tshwm sim ncaj qha rau ntawm qhov chaw. Koj tsis tas yuav rub tag nrho lub cev lub cev tawm ntawm cov kav dej sib txuas.
Kev sib tw Edge
Piv nrog rau qhov zoo tib yam cam khwb cia hlau viav vias kos li qub, sealing cwj pwm sawv ua ib qho txiaj ntsig loj.
Cov pa hlau-disc hard-seal check li qub feem ntau hnav maj mam, thiab cov dej xau tshwm sim tom qab kev pabcuam ntev. Qhov no rubber-coated soft-seal variant tswj xoom micro-seepage dhau lub sijhawm ua haujlwm ntev, txiav tag nrho cov kev pheej hmoo xau thoob plaws koj cov yeeb nkab network.
Kev ua haujlwm mounting tsis xav tau kev siv zog ntau.
Koj tsuas yog ua kom haum nws phim cov kev taw qhia ntws. Tsis xav tau kev hloov kho kom raug siab. Rau lub twj tso kua mis-chaw nres tsheb piping DN200 thiab saum toj no, nws zoo heev speeds-up installation kev vam meej.
Tsawg khiav-nqi kev ua tau zoo, ze-zero li niaj zaus tu.
Core Cheebtsam tuav ruaj ruaj. Thaum cov roj hmab flap muaj hnub nyoog dhau sijhawm, koj tsuas yog hloov qhov no xwb. Cov khoom kim heev overhauls yuav zam tau.
Txoj Cai Ua Haujlwm Ntawm Roj Hmab Disc Viav Vias Valve
Qhib lub voj voog
Nruab nrab ntws tom qab tus xub cim luam tawm ntawm lub tsev nyob valve. Cov dej siab thawb cov roj hmab viav vias nrov plig plawg. Lub zog thawb no ua rau cov roj hmab lub cev muaj zog ntxiv nrog rau cov dej ntws rov qab-siab. Lub flap rotates nyob ib ncig ntawm qia ncej thiab viav vias qhib. Cov kua dej tuaj yeem dhau los ntawm txoj kev ntws mus zoo.
Kaw lub voj voog
Forward-kwj dej qeeb qeeb los yog sim ntws rov qab. Thrust los ntawm cov khoom nruab nrab tuaj yeem ploj mus. Tsav los ntawm roj hmab elastic rebound ua ke nrog rov qab-sab nruab nrab siab, viav vias nrov plig plawg snaps rov qab sai. Nws nias nrees tiv thaiv lub rooj zaum valve. Rov qab-flow nruab nrab tau txais kev thaiv tag nrho, thiab kev tiv thaiv tsis rov qab siv tau.
Installation & Service Notes
Ua ntej koj mount lub check-valve unit, tshem tag nrho cov khib nyiab, vuam slag thiab av hauv cov kav dej. Cov khoom tawv tawv tuaj yeem khawb cov roj hmab nrov plig plawg thiab rhuav tshem kev ua haujlwm.
Mounting kev taw qhia yuav tsum ua raws li cov xub cim rau ntawm vaj tse; rov qab installation yog nruj me ntsis txwv tsis pub.
Ua ib qho kev kuaj pom tsis tu ncua rau sab hauv roj hmab flap. Hloov cov khoom tam sim ntawd yog tias koj pom kev laus, deformation lossis kev puas tsuaj saum npoo.
Tsis txhob siv lub tshuab no nyob rau hauv qhov kub thiab txias, dhau-siab lossis hnyav hnyav ua haujlwm. Cov kev ua haujlwm hnyav li no yuav ua rau ob qho tib si vaj tse thiab roj hmab flap.
