1. Raws li kev xaiv tswj kev ua haujlwm, ntau yam li qub muaj lawv tus kheej lub luag haujlwm, thiab kev saib xyuas yuav tsum tau them rau lawv cov haujlwm sib xws thaum xaiv.

2. Raws li cov kev xaiv ntawm kev ua hauj lwm tej yam kev mob, technical parameters ntawm feem ntau sivBrass Pob Valvesuav nrog kev ntsuas kev ua haujlwm siab, siab tshaj plaws kev ua haujlwm siab, ua haujlwm kub (tsawg kawg thiab siab kawg kub) thiab nruab nrab (corrosiveness, flammability).Thaum xaiv, xyuam xim rau cov lus hais saum toj no ntawm kev ua haujlwm ntawm kev ua haujlwm thiab Cov txheej txheem tsis zoo ntawm lub valve yog qhov zoo ib yam.

3. Xaiv raws li cov qauv kev teeb tsa.Cov qauv kev teeb tsa ntawm cov kav dej muaj xws li cov yeeb nkab xov, flange, ferrule, vuam, hose thiab lwm yam.Yog li ntawd, cov qauv kev teeb tsa ntawm lub valve yuav tsum ua raws li cov qauv kev teeb tsa ntawm cov kav dej, thiab cov kev qhia tshwj xeeb thiab qhov ntev yuav tsum zoo ib yam.

Copper valve installation

1. Lub valve txuas los ntawm cov yeeb nkab xov yog txuas nrog cov yeeb nkab xov ntawm cov yeeb nkab kawg.Cov xov sab hauv tuaj yeem yog cylindrical yeeb nkab xov los yog cov yeeb nkab tapered xov, thiab cov xov sab nraud yuav tsum yog cov yeeb nkab tapered.

2. Lub rooj vag valve nrog cov xov sab hauv yog txuas nrog cov yeeb nkab kawg, thiab qhov ntev ntawm cov xov sab nraud ntawm cov yeeb nkab kawg yuav tsum tau tswj.Txhawm rau tiv thaiv cov yeeb nkab kawg los ntawm kev sib tw ntau dhau los txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau nws, nws yuav tsum tau tshem tawm cov yeeb nkab kawg ntawm qhov kawg ntawm lub taub hau, lub valve lub rooj zaum yuav raug deformed thiab kev ua haujlwm sealing yuav raug cuam tshuam.

3. Rau li qub txuas nrog cov yeeb nkab xov, thaum txhim kho thiab zawm, ntswj yuav tsum tau wrenched ntawm lub hexagonal los yog octagonal ib feem ntawm tib kawg ntawm cov xov, thiab yuav tsum tsis txhob muab wrenched ntawm lub hexagonal los yog octagonal ib feem ntawm lwm kawg ntawm lub valve. kom tsis txhob deformation ntawm lub valve.

4. Flange txuas lub flange ntawm lub valve thiab flange ntawm cov yeeb nkab kawg tsis yog tsuas yog raws li cov specifications thiab qhov ntev, tab sis kuj nrog tib lub nominal siab.

5. Thaum lub valve qia pom tias yuav xau thaum lub sij hawm installation thiab commissioning ntawm lub nres valve thiab lub rooj vag valve, nruj nreem compression txiv ntseej ntawm lub ntim, thiab xyuam xim rau kom tsis txhob muaj zog ntau dhau, tsuav yog tsis muaj to.
