Kev sib khi ntawm lub pob hluav taws qhuav valve disc thiab lub rooj zaum roj hmab foob yog qhov tseem ceeb, thiab cov roj hmab foob yog cov khoom tseem ceeb los xyuas kom meej nws sealing.
Qhuav hluav taws valve disc thiab valve rooj roj hmab foob EPDM Gaskets
Cov khoom siv
Ethylene propylene diene monomer (EPDM)
Kev laus-resistant; tsis yooj yim rau hardening thiab cracking. Ua tau zoo tiv thaiv kev yaig los ntawm ultraviolet rays, ozone thiab ntau yam tshuaj lom neeg, thiab yog qhov tsim nyog rau ntau yam kev ua haujlwm hnyav uas yuav raug ntsib hauv kev tiv thaiv hluav taws.
Zoo siab thiab tsis kub tsis kam, muaj peev xwm ua hauj lwm ruaj khov nyob rau hauv ntau qhov kub thiab txias, kom ntseeg tau tias thaum muaj hluav taws kub hnyiab, txawm nyob rau hauv qhov kub thiab txias, nws tuaj yeem tswj tau cov nyhuv sealing txhim khu kev qha los tiv thaiv qhov nruab nrab to thiab ua kom muaj kev ua haujlwm zoo. qhov hluav taws kub tiv thaiv system.
Kev Ua Haujlwm Zoo
1. Kev sib khi zoo heev: Cov roj hmab foob tuaj yeem tsim kom nruj nrog lub valve disc thiab lub rooj zaum valve, tiv thaiv kom tsis txhob muaj roj, kua thiab lwm yam xov xwm, nrog rau kev sib khi siab, txo cov hluav taws kev nyab xeeb los ntawm kev xau.
2. Kev muaj peev xwm rov qab tau zoo: Thaum lub sijhawm qhib thiab kaw ntawm lub valve, cov roj hmab foob tuaj yeem ua kom muaj kev sib khi zoo, txo qhov kev pheej hmoo ntawm kev tawg los ntawm qhov deformation ntawm lub foob thiab txhim kho lub neej kev pab cuam thiab kev ua haujlwm ntawm lub valve. .
3. Kev tiv thaiv kev tawm dag zog: Nws tuaj yeem tiv taus ntau yam xov xwm uas feem ntau siv hauv kev tiv thaiv hluav taws, xws li dej, ua npuas dej, tshuaj tua hluav taws, thiab lwm yam. Nws yuav tsis raug tshuaj lom neeg vim kev sib cuag nrog cov xov xwm no, ua rau kev ua haujlwm tsis zoo. , ua kom ruaj khov ua haujlwm hauv cov xwm txheej tua hluav taws sib txawv thiab muab lub hauv paus ruaj khov rau kev ua haujlwm zoo ntawm kev tua hluav taws.
Khoom Installation thiab tu
1. Kev txhim kho: Thaum txhim kho cov roj hmab ntsaws ruaj ruaj, xyuas kom meej tias cov disc thiab lub rooj zaum saum npoo yog huv si, tiaj tus, tsis muaj impurities, roj thiab puas. Cov txheej txheem kev teeb tsa yuav tsum maj mam, tsis txhob ncab ntau dhau los yog sib tw ntawm lub foob, kom nws tuaj yeem haum ib txwm muaj thiab sib npaug ntawm qhov sib khi. Tom qab kev teeb tsa, yuav tsum tau ua qhov kev sim ua ntej sealing los xyuas kom meej tias lub foob raug ntsia rau hauv qhov chaw thiab tsis muaj qhov xau.
2. Kev tu: Txheeb xyuas cov roj hmab ntsaws ruaj ruaj tsis tu ncua kom pom tias muaj kev hnav, kev laus, deformation, thiab lwm yam. Yog tias lub foob nto me ntsis puas, nws tuaj yeem kho nrog cov roj hmab tshwj xeeb kho; yog tias qhov kev puas tsuaj loj heev, nws yuav tsum tau hloov lub sijhawm. Nyob rau tib lub sijhawm, ua kom qhov chaw ib puag ncig ntawm lub valve kom huv si kom tsis txhob muaj plua plav thiab cov khib nyiab los ntawm kev ua raws li lub foob thiab cuam tshuam rau nws txoj kev sib khi.
hloov cov cai
Thaum cov roj hmab ntsaws ruaj ruaj muaj cov xwm txheej hauv qab no, lawv yuav tsum tau hloov pauv raws sijhawm: Ua ntej, qhov kev sib khi ua haujlwm tau txo qis, kev xau tshwm sim, thiab nws tsis tuaj yeem daws tau los ntawm kev ntsuas kev kho; thib ob, cov ntsaws ruaj ruaj yog cov hnub nyoog hnyav, tawv, tawg lossis deformed, thiab tsis tuaj yeem rov qab elasticity; thib peb, tom qab siv mus ntev (feem ntau txiav txim siab raws li kev saib xyuas thiab kev siv tiag tiag ntawm kev tiv thaiv hluav taws, xws li 5-8 xyoo), txawm tias tsis muaj kev puas tsuaj rau lub ntsej muag, kom ntseeg tau qhov kev ntseeg ntawm lub Kev tiv thaiv hluav taws, kev hloov pauv yuav tsum xav txog. Thaum hloov, nco ntsoov siv cov khoom siv roj hmab zoo ntawm tib tus qauv thiab cov lus qhia tshwj xeeb raws li tus thawj coj los xyuas kom meej qhov kev sib khi zoo thiab kev ua haujlwm tag nrho ntawm lub valve, thiab muab kev tiv thaiv txuas ntxiv thiab txhim khu kev ruaj ntseg rau hluav taws.
Peb qhov hluav taws kub qhuav valve disc thiab valve lub rooj roj hmab foob tuaj yeem kho tau. Thov muab cov khoom siv tshwj xeeb uas yuav tsum tau ua thiab kos duab loj kom peb thiaj li txiav txim siab kom raug.
