Yuav ua li cas xaiv Copper Ball Valves thiab zam pitfalls?

    Brass pob li qubyog "cov khoom me me" hauv cov dej hauv tsev, tab sis tus nqi ntawm 1 RMB txog 50 RMB ntawm kev ua lag luam hides ntau "zinc alloy ntxiab." Qhov tseeb, xaiv txoj cai tooj liab pob valve tsis nyuaj - coj Yuanlun tooj dag pob li qub ua piv txwv. Los ntawm cov khoom siv mus rau kev ua tau zoo, cov khoom lag luam ua tau zoo tiag tiag yog nws tus kheej "cov ntawv pov thawj ntseeg tau."

1. Cov ntaub ntawv pov thawj: Peb Tricks kom pom "Fakes," Yuanlun yog "Cov Khoom Siv Hluav Taws Xob Tiag"

Qhov hnyav + Magnet Test:
Lub Yuanlun DN15 tooj dag pob valve hnyav dua lossis sib npaug li 200 g (ntau tshaj 180 g tus qauv tooj liab tiag tiag) thiab hnov ​​​​zoo hauv tes. Thaum cov hlau nplaum raug kaw, lub valve lub cev qhiatsis muaj attraction(tshem tawm zinc-alloy impurities uas muaj hlau).

Cov cim qhia ntxaws:
Yuanlun valve lub cev tau pom meej meej nrog cov lej qib tooj liab, thiab cov xov chaw nres nkoj tau meej yam tsis muaj burrs. Feem ntau cov teeb meem hauv cov khoom tsis zoo xws li cov xov tawg lossis cov hniav tsis zoo yog qhov tsis tuaj.

Hlawv Test:
Thaum scorched, Yuanlun tooj liab pob valve tsuas yog oxidizes thiab tig dub, tsis muaj pungent tsw. Hauv qhov sib piv, zinc-alloy imitations emit pa luam yeeb dawb thiab qaub tsw -qhov no kuj yog vim li cas Yuanlun hais kom siv high-purity tooj dag.

2. Performance Parameters: Yuanlun's Label muaj "Kev Nyab Xeeb Code"

Cov lus qhia tshwj xeeb ntawm cov khoom siv tooj dag pob valve yog "kev lees paub tsis pom." Yuanlun tooj dag pob li qub 'cov ntawv sau nrog kev ruaj ntseg:

① Kev ntsuas siabNP16(nrog rau 1.6 MPa), muab 3 npaug ntawm kev nyab xeeb ntawm cov dej hauv nroog.

② Ua haujlwm kub-25℃rau 160 degree, npog tag nrho cov xwm txheej los ntawm kev siv dej hauv tsev mus rau cov dej kub hauv qab.

③ Certified nrog ob lubGB/T 8464lub teb chaws tus qauv thiab cov ntaub ntawv pov thawj kev nyab xeeb dej, ua rau nws muaj kev nyab xeeb txawm tias cov kav dej ncaj qha.

3. Cov lus qhia txog kev teeb tsa: Yuanlun + Kev Ua Haujlwm Zoo=10+ Xyoo ntawm Kev Pabcuam Ntxiv

Xaiv cov khoom tsim nyog kuj txhais tau tias txhim kho nws kom raug:

① Yuanlun valve lub cev muaj cov xub ntshiab qhia txog kev khiav dej num. Kev txhim kho nws rov qab tuaj yeem txo qhov ntws los ntawm 30%, yog li kev sib dhos yog qhov tseem ceeb.

② Thaum qhwv Teflon daim kab xev, ua raws li Yuanlun cov kev taw qhia: " qhwv counter-clockwise 5-8 lem," ua ke nrog cov xov meej los tiv thaiv sab to.

③ Yuanlun valve tuav yog tsim los nrog kev ua haujlwm tshem tawm hauv siab. Rau cov qauv DN20, tsuas yog 8 cm vojvoog yog xav tau rau kev ua haujlwm zoo dua rau ntawm / tawm.

Q&A: Cov lus nug ntau txog Yuanlun Brass Ball Valves

Q1: Tau Yuanlun tooj dagpob li qub siv rau hauv cov cua sov hauv qab?
A: Yog lawm!Lawv qhov kub thiab txias tsis kam ntawm -25℃txog 160℃tso cai rau kev ruaj khov nrog cov cua sov hauv qab dej kub, tsis muaj deformation nyob rau hauv qhov kub thiab txias.

Q2: Lub sijhawm lav rau Yuanlun tooj dag pob li qub yog dab tsi?
    A:Yuanlun tooj dag pob li qub tuaj nrog 2 xyoo warranty. Ua tsaug rau lawv cov khoom siv thiab cov khoom siv tes ua haujlwm, lawv lub neej ua haujlwm tau ntev tshaj 2 xyoos.

Thaum xaiv lub pob tooj dag, tsis txhob saib tus nqi - cov khoom xws li Yuanlun, ua los ntawm cov ntaub ntawv tiag, yog ob qho tib si "tus neeg saib xyuas me me" rau koj lub cev dej thiab "kev xaiv tsis txhawj xeeb" rau kev siv mus ntev.
