What is a DZR Valves？
DZR valves, Kuj hu ua ib dezincification resistant valve, ua tej yam brass. Piv txwv,CW602N, CW625N thiab CW724R. Dezincification ua corrosion, Mas thaum lub brass raug ib puag ncig uas muaj concentrations ntawm moisture thiab oxygen. Thov rau DZR valves yog pheej zuj zus vim lawv tsis raug nqi tsawg, corrosion kuj, muaj zog, hluav taws xob conductivity thiab machinability. Tus cwj pwm no yuav pab tau peb li cas, Lawv ua tau zoo dua tej khoom tooj liab thiab lwm yam alloys.
Bronze Valve yog dab tsi?
Lub ntsiab ntawm bronze valves yog tin thiab tooj liab. Lwm alloying hais, xws li aluminum los yog manganese, Ntxiv rau zinc thiab tooj liab kom tau cov khoom. Piv txwv,C83600 , C84400 thiab C89833.
Piv rau DZR khoom, bronze lawm siv rau qhov ntev, tiam sis nws yog maj mam tau abandoned vim nws ua nqi.
Qhov txawv hauv Specifications ntawm DZR thiab Bronze
Mas txawv yog cov tshuaj composition thiab lub cev zog:

DZR Valve & Bronze Valve ua hauj lwm kub
DZR valves muaj ib tug kub ua hauj lwm kub uas ntau yam los ntawm-20°C rau 120°C thaum piv rau tsoos brass valves. Bronze valves ntawm qhov tod tes muaj ntau dua ua hauj lwm kub. Qhov chaw ua hauj lwm kub rau bronze valves nyob ntawm tus specific alloy composition thiab daim ntawv thov. Piv txwv, Ib aluminum bronze valve yuav kov kub xws li ntawm-100°C rau 400°C.
DZR Valve & Bronze Valve ua hauj lwm siab
Bronze valve lub siab kuj nyob ntawm nws cov alloy composition, valve tsim, thiab daim ntawv thov kev pab. Rau cov ntaub ntawv uas tsis muaj siab, Lub siab ua hauj lwm yuav nyob ib ncig ntawm 150 psi thaum high-pressure daim ntawv thov yuav mus txog 1500 psi. Ua txhais tau tias, DZR valves kuj ntau yam nyob rau hauv kev ua hauj lwm siab nyob ntawm ntau yam xws li daim ntawv thov, valve tsim, siv khoom siv, thiab loj 17. Qhov no txhais tau tias koj yuav cuag ib lub siab ua hauj lwm siab uas tsis muaj tsawg li 150 psi thiab siab li siab 1500 psi los yog ntau dua.
Vim li cas thiaj siv DZR valve
- Qauv Qhia Txog Kev Coj Noj Coj Ua: DZR valves muaj ib lub cev thickened qauv. Cov khoom nyoos nyoos nyob rau hauv nws cov composition muaj ib lub zog tensile heev. Nws tsis zoo xwb muab nws lub kaw lus thicker, tiam sis kuj enables kev tiv thaiv. No nruj alignment ntawm DZR valves ua rau lawv mas resistant kom siab.
- Corrosion Resistant: Cov tshuaj composition ntawm DZR reveals muaj arsenic. Nws ntxiv rau lub corrosion-resistant zog ntawm DZR valves. dhau li, DZR valves zoo paub txog lawv kev kawm zoo kawg li nyob rau hauv seawater. Lawv yuav to taub cov ntsiab lus ntsev ntawm seawater tsis corrosion los yog puas.
- tswj: DZR valves yog zoo meej tswj dej ntws los yog lwm yam kua. Lawv nres zinc los tau corrosion. Yog li ntawd, vim, tsis muaj zinc tawm hauv cov kua ntws. DZR valves muaj zoo tswj cov khoom nyob rau hauv ntau hom khoom. Lawv zoo tshaj rau dej tswj lub hom phiaj. Tshwj xeeb tshaj yog nyob rau hauv rooj plaub ntawm dej potable, Lawv tsis pollute dej nrog cov hlau tsis tau hlau.
Vim li cas thiaj siv Bronze valve
- Ductile Cuab yeej: Lub plumbing fittings yuav tsum kam nrog ntau yam kev hloov. Feem ntau, Peb yuav tsum tau ua me ntsis kho thaum installing valves. Bronze valves muaj ntau yooj ywm. Peb yuav ceev nrooj kos lawv los ntawm tshav kub kub ntawm ib qhov kub.
- Nqi zoo: Bronze valves yog tej zaum tus tsuas nyob rau hauv lub lag luam uas raug nqi tsawg tshaj li lwm metallic alloys. Lawv muab peb nrog cov kev pab zoo version ntawm kev pab los khaws nws pob nyiaj siv-tus phooj ywg. Nws yog ib yam ntawm cov khoom vim li cas koj yuav tsum siv bronze valves.
- Kuj tiv thaiv Saltwater: ob peb metals, brass, npaum li cas tiam sis tsis tau ua zoo nyob rau hauv cov dej ntsev. tiam sis, bronze yog zoo meej rau kev soj ntsuam nrog saltwater hauv marine haujlwm. Nws yog equally zoo rau soft thiab dej nyuaj. Peb yuav hais tias bronze yog zoo ntawm corrosion kuj thiab saltwater kuj.
Xaus
DZR thiab bronze yog ob npaug hlau alloys. Lawv txawv hauv ob peb zog, Tiam sis muaj nws tus kheej functions. Yog koj xaiv ib yam ntawm cov khoom no, Peb hais kom koj tsom xam koj cov kev cai kom txhij txhua. Ces, Xaiv txoj cai nyob ntawm tus Valve tawm ntws, txias, siab ntev thev. Nws yuav pab kom koj tau qhov zoo tshaj plaws uas stunning nta.
