Nws paub zoo tias kev puas tsuaj hlau hlau muaj kev cuam tshuam loj heev rau lub neej valve, kev ntseeg siab thiab kev pabcuam lub neej.Qhov kev txiav txim ntawm txhua yam thiab corrosive yam ntawm cov hlau ua rau kom tag nrho cov hnav ntawm qhov chaw sib cuag.Tag nrho tus nqi ntawm kev hnav ntawm qhov sib txhuam ntawm lub valve thaum ua haujlwm.Thaum lub sijhawm ua haujlwm ntawm lub valve, cov chaw sib txhuam yog hnav thiab puas vim yog kev sib xyaw ua ke ntawm cov tshuab thiab tshuaj lom neeg lossis electrochemical kev sib cuam tshuam ntawm cov hlau thiab ib puag ncig.Rau cov li qub, cov huab cua puag rau lawv cov kav dej ua haujlwm yog qhov nyuaj, thiab muaj cov hydrogen sulfide, carbon dioxide thiab qee cov organic acids hauv cov xov xwm xws li roj, nkev roj thiab dej reservoir ua rau lub zog puas tsuaj ntawm cov hlau nto thiab sai sai poob. muaj peev xwm ua haujlwm.

Cov tshuaj corrosion ntawm cov hlau nyob ntawm qhov kub thiab txias, cov khoom siv thauj khoom ntawm qhov sib txhuam, cov sulfides muaj nyob rau hauv cov ntaub ntawv lubricating, kev ruaj ntseg ntawm cov kua qaub tiv thaiv, kev sib cuag ntev ntawm qhov nruab nrab, catalysis ntawm cov hlau rau cov txheej txheem nitriding, qhov ceev ntawm molecule-rau-hlau hloov ntawm cov ntaub ntawv corrosive, thiab lwm yam.Yog li ntawd, cov hlau valve los tiv thaiv corrosion txoj kev (los yog ntsuas) thiab daim ntawv thov ntawm cov khoom hluavtaws li qub, yuav dhau los ua ib qho ntawm cov kev tshawb fawb txog kev lag luam valve tam sim no.

1. Anti-corrosion ntawm Hlau Valve

Hlau Valves tiv thaiv corrosion los ntawm cov txheej txheej tiv thaiv (xim, xim, cov khoom siv lubricating, thiab lwm yam) uas tiv thaiv lub valve los ntawm corrosion thaum lub sij hawm tsim khoom, khaws cia, kev thauj mus los, thiab siv.

Txoj kev tiv thaiv corrosion ntawm Hlau Valve nyob ntawm qhov yuav tsum tau muaj lub sijhawm tiv thaiv, kev thauj mus los thiab kev khaws cia, valve siv cov yam ntxwv thiab cov khoom siv, tau kawg, los txiav txim siab txog kev lag luam ntawm kev nqa cov khoom tiv thaiv.

Muaj plaub txoj hauv kev tseem ceeb ntawm kev tiv thaiv corrosion rau Hlau Valves thiab lawv cov khoom:

1.1 Tso cov tshuaj tiv thaiv corrosion rau hauv qhov chaw vapor (coated nrog blotting ntawv, tshuab los ntawm cov khoom chamber, thiab lwm yam).

1.2 Siv cov tshuaj thaiv dej thiab cawv.

1.3 Siv cov txheej nyias nyias ntawm cov khoom siv tiv thaiv corrosion rau saum npoo ntawm lub valve thiab nws qhov chaw.

1.4 Siv cov yeeb yaj kiab los yog cov yeeb yaj kiab polymer rau saum npoo ntawm lub valve thiab nws qhov chaw.

2. Kev siv cov khoom siv Valve

Synthetic li qub yog superior rau hlau li qub nyob rau hauv ntau corrosive tej yam kev mob, thawj nyob rau hauv corrosion kuj, thib ob nyob rau hauv net hnyav, thiab lawv lub zog nyob ntawm seb cov duab, kev npaj, thiab cov xov tooj ntawm reinforcing fibers.(feem ntau, qhov ntau dua qhov feem pua ​​​​ntawm fiber ntau, qhov ntau dua lub zog ntawm cov khoom sib xyaw.)

Hauv cov ntawv thov Valve, cov ntsiab lus hnyav ntawm cov fiber ntau yog nyob rau hauv thaj tsam ntawm 30% -40%, thiab nws cov tshuaj lom neeg ruaj khov yog txiav txim siab los ntawm cov resin noumenon yam ntxwv ntawm cov fiber ntau encapsulated hauv cov khoom kawg.Hauv cov khoom siv hluavtaws, cov khoom siv polymer lub cev tuaj yeem yog cov Thermoplastic (xws li PVC-polyvinylidene fluoride, PPS-poly (p-phenylene sulfide), thiab lwm yam) los yog thermosetting resin (xws li polyester, ethylene thiab epoxy, thiab lwm yam.) .

Lub thermosetting resin tuav nws lub zog ntawm qhov kub siab dua li Thermoplastic resin (piv txwv li cov thermosetting resin muaj qhov kub siab dua thermal deformation).
