I. Xaiv cov khoom tseem ceeb thiab cov qauv ntawv pov thawj
1. Kev tsom xam ntawm tooj dag alloy muaj pes tsawg leeg
Tooj liab-zinc piv: Cov qauv tooj tau zoo feem ntau yog adopts H59 \/ H62% {% kom ntseeg tau tias qhov sib npaug ntawm lub zog thiab corrosion tsis kam;
Mob los tswj tswj: Cov ntsiab lus txhuas yuav tsum ua raws li RoHS 2. {} (Tsawg dua}. 1%) kom tau raws li EU kev tiv thaiv EU puag ncig; impurities xws li sulphor thiab phosphorus yuav tsum qis dua Astm B16 tus qauv los tiv thaiv cov hauv paus.
(Tus neeg yuav khoom tsom: Cov ntaub ntawv ncaj qha cuam tshuam valve lub neej, thiab cov ntawv ceeb toom xeem ntawv yuav tsum tau)
2. Cov ntawv pov thawj tseem ceeb
Cov Txheej Txheem Thoob Ntiaj Teb: ISO 9001 (Kev Tswj Xyuas Zoo), ISO 14001 (ib puag ncig cov khoom lag luam ib puag ncig);
Kev Lag Luam Kev Lag Luam:
NSF \/ ANSI 61 (Kev haus dej nyab xeeb, Asmeskas Kev Lag Luam Kev Lag Luam);
Wras (British Dej Ua Haujlwm Daim Ntawv Pov Thawj);
DVGW (German roj thiab dej koom Kev Lag Luam Txuj Ci).
(Kev Xav Tau Tshwj Xeeb: Ntawv pov thawj yog "Pass" rau kev lag luam export lossis high-aite kev lag luam yuav tsum tau meej)
Ii. Key durabils thiab ntawv pov thawj
1. Corrosion Resistance
Cov tshuaj tsuag ntsev: ASTM B117 txheem, simulates marine lossis high humidity ib puag ncig, thiab tsis muaj xeb liab tom qab 720 teev ntawm kev sim;
Acid Nruab Nrab Kev Ntsuas: So kom muaj cov kua qaub nrog pH =5 ({{{}}}}}} hnub saum npoo tswm corrosion<0.1mm/year.
2. Cov khoom siv kho kom zoo
Kev Xeem Mus Kuaj: En 12266 Txuj Ci, 5000 Cycles ntawm 1.5 zaug ntawm Nominal Siab (PN16 → 24bar) tsis muaj tshuaj xau;
Lub zog tensile: ntau dua los yog sib npaug ntawm 350 MPa (tooj dag lub cev), kev sib txuas ntawm lub valve qia thiab lub valve lub cev yuav tsum dhau 10, {
3. Cov ntsuas kub yoog
Kub siab laus: {-20 degree ~ 150 degree qhov sib txawv cuam tshuam (astm b584), xyuas qhov ruaj khov ntawm cov khoom sib khi (PTFE \/ graphite).
3. Cov txheej txheem optimized ua kom zoo los txhim kho durability
1. Forging Txheej Txheem Vs. Casting Txheej Txheem
Forged tooj dag: ntom nplej, 30% ntau dua compressive zog, tsim nyog rau kev ntsuas siab (xws li cov tshuaj lom neeg);
Precision Casting: Tus nqi qis dua, tab sis yuav tsum tau X-Ray Qhov Ntsuas Kom Paub (ASTM E505) los tshawb xyuas sab hauv cov tsis xws luag.
2. Nto Kho Tshuab
Electropated nickel txheej: thickness ntau dua los yog sib npaug rau 8μm, txhim kho cov hnav tsis kam (raws li Astm B733 txuj ci);
Kev Kho Mob Passivation: chromate passivation zaj duab xis (mil-c {1}} e chav vag 3), txhim kho ntsev txau tiv thaiv.
4. Kev ruaj khov ntev ntawm cov khoom siv sib txuas lus
1. Cov Khoom Siv Raw Traceeability
Cov neeg muab ntawv pov thawj rau cov neeg muag khoom siv TüV SüV SüV SüV Ntawv pov thawj, thiab txhua pob yog nrog daim ntawv pov thawj tsom xam);
Tsim cov khoom siv coding system kom ua tiav kev taug qab tag nrho los ntawm cov khoom raw los ua cov khoom tiav.
2. Kev laus database thiab kev txhim kho mechanismism
Nrig cov ntaub ntawv siv rau ntau tshaj 5 xyoos thiab tshawb xyuas cov qauv tsis raug (xws li Valve qia daig,
Kev txhim kho kev txhim kho: piv txwv li, hloov kho lub valve cov kav cov khoom rau silicon tooj dag (C87600) kom txo cov kev sib txhuam.
