Cov tub ntxhais sib txawv ntawm tooj dag check valve thiab cim bronze part valve yog los ntawm cov khoom muaj pes tsawg leeg thiab kev ua tau zoo. Lub ntsiab sib txawv yog raws li hauv qab no:
1. Cov Khoom Siv Cov Khoom Siv Thiab Cov Neeg Kho Tshuab
Tooj dag check valve:
Composition: feem ntau yog tooj liab-zinc alloy (zinc cov ntsiab lus 20% -40%), txhuas, txhuas ntxiv rau txhim kho kev txiav lossis corrosion tsis kam.
Kev Ua Tau Zoo: Zoo plastonity thiab kev ua tau yooj yim thiab kev sib sau, tab sis cov tawv tawv, tab sis tsis tshua muaj zog (tensile lub zog ntawm txog 300-500mpa), tswj hwm dav dav.
Bronze Kos Valve:
Composition: tsuas yog tooj liab-tin alloy (tin cov ntsiab lus 3% -14%), tuaj yeem muaj txhuas, phosphorus thiab lwm cov ntsiab lus los txhim kho lub zog.
Kev ua tau zoo: Lub zog hardness (tensile muaj zog tuaj yeem mus txog ntau dua 600MPA), muaj zog tawv dua tooj dag, tab sis nyuaj rau cov txheej txheem.
2. Corrosion tsis kam thiab siv xov xwm
Tooj dag li qub: zoo corrosion tiv thaiv hauv dej huv, dej sov thiab thaj chaw ammoochology thiab ammonium thiab ammonium ntsev (nquag ua rau muaj kev ntxhov siab corrosion).
Muaj feem xyuam nrog cov xwm txheej dej: HVAC dej kub kub, cov roj av qis hauv tsev (xws li H14w tooj dag viav vias kos valing kos valve).
Bronze Li Li Cas: Zoo heev Seasater corrosion, haum rau cov kua dej (xws li nkoj ballast dej, dej hiav txwv kom qhuav).
Nws ua tau zoo dua tooj dag hauv acidic media (xws li tsis muaj zog sulfuric acid), tab sis ob leeg yuav tsum tau siv nrog kev ceev faj hauv hydrochloric acid ib puag ncig.
3. Tus nqi thiab kev lag luam
Tooj dag li qub: Tsawg cov khoom siv Raw, cov khoom siv tsis muaj nqi, kev ua tau zoo, tsim nyog rau pej xeem cov xwm txheej nrog cov peev nyiaj tsawg.
Bronze li qub: vim tias nws muaj cov hlau nplaum zoo xws li tin thiab txhuas, tus nqi yog 30% siab dua tooj dag, thiab kev ua khoom siv hluav taws xob loj.
4. Cov ntaub ntawv raug cai
Tooj dag check valve:
Cov dej kub kub ntawm cov raj dej pipeline ntawm HVAC system (tiv thaiv kev sib xyaw ntawm cov dej txias thiab dej kub);
Qhov hluav taws xob qis hauv tsev thiab hluav taws kub tso hluav taws xob (yuav tsum tau sib phim nrog dej rauj tshem tawm, xws li DN tsawg dua lossis sib npaug nrog 50 threaded txuas valve).
Bronze Kos Valve:
Roj / Dej Hiav Txwv Kev Siv Hluav Taws Xob ntawm Nkoj Fais Fab System;
Corrosive nruab nrab raj dej tshuaj (xws li acid-resistant twj tso kua dej);
Kev siab siab thiab siab ua haujlwm siab (qee cov kab mob tooj daj (qee cov xim tooj daj tsis tuaj yeem tiv taus kub siab tshaj 400 degree).
⚠️ Kev Xaiv Xaiv
Media Compatibility: tooj dag li cas txwv tsis pub muaj nyob rau hauv ammonia-muaj ib puag ncig; Bronze li qub yuav tsum tau siv nrog kev ceevfaj rau cov kua muaj cov khoom muaj khoom (zam kom tsis txhob hnav ntawm cov khoom sib khi).
Qib siab: Qiv txhab yog qhov haum rau qhov nruab nrab thiab cov tshuab siab siab (xws li PN25 thiab siab dua).
Txij Nkawm Cov Nqi: Nrig Nrig Li Qub Yog Yooj Yim Los Hloov Tab sis Muaj Lub Neej Luv; Bronze li qub yog muaj zog heev thiab haum rau cov kav dej tseem ceeb uas ua haujlwm tau ntev.
