Daim tshev txiav li cas yog li qub uas yog li qub uas yuav qhib thiab kaw raws li cov nruab nrab ntawm lub siab. Lawv feem ntau siv los tiv thaiv backelines thiab tau siv dav hauv kev lag luam xws li tshuaj lom neeg, khoom noj thiab dej haus, thiab chaw muag tshuaj. Piv rau cov tsoos hlau kos duab hlau, cov tshuaj ntsuab txiav cov txiaj ntsig zoo rau cov ntawv thov corrantance, kev tsim kho corrosion, thiab tus nqi qis.
Cov qauv thiab cov ntsiab cai ua haujlwm
Cov kab xev Yas txiav feem ntau muaj ib lub cev lub cev, disc, caij nplooj ntoos hlav (rau qee cov qauv), thiab ntsaws ruaj ruaj. Lawv cov qauv tseem ceeb yog txhaj tshuaj - moulded los ntawm kev ua kom zoo nkauj (xws li PP, PVC, CPVC, thiab PVDF). Lub discens thaum mus rau pem hauv ntej thiab cia li kaw vim lub ntiajteb txawj nqus lossis lub caij nplooj ntoo hlav thaum rov qab ntws, tiv thaiv backflow. Ua raws li lawv cov qauv, cov tshuaj xyuas cov yas yuav raug faib ua viav vias, nqa thiab npauj npaim hom. Viav vias sceck li qub yog tsim nyog rau loj {5} txoj hauj lwm txoj kab li qub
Cov Khoom Siv Tseem Ceeb thiab Cov yam ntxwv
Cov ntaub ntawv xaiv rau cov yas xyuas cov khoom cuam tshuam ncaj qha cuam tshuam lawv daim ntawv thov ntau li:
• PP (polypropylene): tiv taus General cov kua qaub thiab Alkalis, haum rau cov tshuaj ua kom dej me me ntawm qhov kub txog 80 degree.
• PVC (polyvinyl chloride): tus nqi qis thiab cov kua qaub zoo thiab alkali tsis kam, tab sis kub tsis kam (tsawg dua los yog sib npaug rau 60 degree). Feem ntau siv nyob rau hauv cov dej so thiab tso kua dej.
• CPVC (chlorinated polyvinyl chloride): Cov cua sov siab tiv taus li ntawm 95 degree, nrog cov dej ntws tsis zoo, haum rau cov dej kub lossis muaj huab cua muaj teeb meem.
• PVDF (polyvinylidene fluoride): kev kub siab dhau (tsawg dua los yog sib npaug rau cov ntaub ntawv uas muaj zog xws li cov ntaub ntawv uas muaj kev lag luam xws li cov qauv kev lag luam thiab cov khoom siv hluav taws xob.
Cov tshuaj txhuam cov yas yog lub teeb ci ntsa iab thiab yooj yim rau nruab, thaum tsis txhob muaj cov teeb meem corrosion ntawm cov kav hlau. Lawv yog qhov tshwj xeeb rau kev xa cov kua dej uas muaj chloride ions, acids, hauv paus, thiab ntsev, thiab ntsev.
Daim Ntawv Thov Kev Pab Cuam
1.Txoj kev kho mob: Siv thaum lub twj tso kua mis thiab tank inlets thiab outlets los tiv thaiv dej rauj thiab backflow tov.
2. Demical cov txheej txheem: Cov tshuaj pleev cov tshuaj yas ua cov tshuaj zoo dua piv rau cov hlau uas muaj cov roj (xws li cov kua qaub thiab alkalis).
3.food thiab cov kws tshuaj thiab kuaj xyuas cov yas (xws li cov qauv pvdf) uas tau sib ntsib hauv cov tshuab ntxuav huv.
4.HVAC: Kev ntsuas cov yas ua kom zoo li qub cov siab txo qis hauv HVAC cov tshuab thiab ua kom zoo siv hluav taws xob.
Qhov zoo thiab cov kev txwv
Qhov Zoo:
• Muaj feem xyuam: Tiv thaiv ntau yam tshuaj lom neeg tsis muaj tshuaj lom neeg yam tsis muaj qhov xav tau ntxiv.
• Lub teeb yuag: kev teeb tsa yooj yim thiab txo cov piping load.
• Tus nqi qis: kev lag luam ntau dua li cov li qub hlau, tshwj xeeb tshaj yog nyob rau hauv- txoj kab uas hla ntawm txoj kab uas hla hla.
• Kev Txij Nkawm Me: Tsis muaj cov hlau me me, ua rau lub neej muaj kev pabcuam ntev.
Txwv:
Cov kev txwv kub: feem ntau cov khoom siv yas tsis haum rau high {}} kub ncu lossis ultra- dej txias.
• Muaj lub zog tsawg: txhawb cov yas lossis cov qauv sib xyaw tsim kom muaj rau qhov siab - qhov kev siv siab.
Cov Lus Taw Qhia Xaiv
Thaum xaiv cov yas kos lub valve, xav txog hom xov xwm, kub, thiab ntws tawm tsis tau. Piv txwv li, PVDF yog qhov nyiam thaum muab cov kua siab siab high-} purity purity kua. For high system pressures, a spring-assisted quick-closing design can be selected to reduce the risk of water hammer. Ib qho ntxiv, xyuas kom meej tias txoj kev sib txuas pua valve (xws li cov nplaum sib txuas, kub yaj, lossis cov flanges) tau sib haum kom tsis txhob muaj cov dej xau.

Cov tshuaj txhuam cov roj hmab yas, nrog lawv cov khoom siv thiab ua haujlwm zoo, yog qhov kev xaiv zoo tagnrho rau cov khoom siv hlau thiab chaw nyob. Nrog cov kev nce qib hauv kev ua tshuab plastics, kev ua tau zoo ntawm cov tshuaj pleev cov yas yuav ua txuas ntxiv txhim kho, nthuav tawm lawv cov ntawv thov tau txais txiaj ntsig hauv cov ntawv thov complex ntxiv. Cov kev xaiv thiab kev teeb tsa tsim nyog yog qhov tseem ceeb los ua tiav kev ua tau zoo rau kev ua tau zoo rau kev ua tau zoo ntawm kev kawm tau raws lawv cov kev xav tau.
