Raws li cov cuab yeej tseem ceeb rau kev ntsuas kev noj dej, cov dej tsis sib haum rau siab {{}}}} lub sijhawm ua haujlwm. Cov khoom xaiv rau cov dej ntawm cov khoom siv dej ncaj qha cuam tshuam nrog cov cuab yeej siv hluav taws xob ncaj ncees, corrosion tsis kam, thiab metering qhov raug. Cov ntaub ntawv cov khoom siv xws li tooj dag, engineering plastics, stainless hlau, thiab roj hmab. Txhua cov khoom siv tau siv nyob rau hauv cov khoom sib txawv vim nws lub cev thiab tshuaj lom neeg.
Tooj dag yog ib txwm ua ib qho khoom tseem ceeb rau cov khoom siv dej ntxiv, tshwj xeeb} cov kabmob lossis cov khoom siv, thiab lub cev valve. Tooj dag muaj cov khoom siv zoo heev zog, hnav tsis kam, thiab dej siab tsis kam. Nws cov khoom siv tshuaj tua kab mob ua rau nws muaj kev nyab xeeb dua thiab txhim khu kev qha ntau hauv cov dej haus. Txawm li cas los xij, tooj dag yog tus nqi kim thiab raug rau patina tshwm sim los ntawm cov xib hwb hauv dej. Yog li no, qee thaj chaw muaj nickel - plated los yog zinc {{6} plated los txhim kho corrosion tsis kam.
Kev tsim kho kom zoo nkauj uas ua rau muaj kev pheej hmoo (xws li Abs thiab Nylon) tau tsis ntev los no hauv tsis yog}}} qhov kev sib txuas thiab meter phiaj thiab meter nkhaus. Cov ntaub ntawv no yog lub teeb pwm, corrosion - tiv taus, thiab tawm tsam kev tawm tsam los ntawm dej tshuaj, ua tau zoo nyob rau hauv cov chaw noo noo. Tus nqi qis thiab yooj yim ntawm cov khoom siv yas ua rau cov loj {}}}} kub kuj yuav yog qhov qis dua me ntsis rau cov hlau ntawd.
Stainless hlau feem ntau siv nyob rau hauv valve cores lossis txuas rau high -}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} kawg dej meters. Nws cov kev nyab xeeb siab tsis kam thiab kev nyab xeeb kev nyab xeeb ua rau nws haum rau kev siv hauv thaj chaw uas muaj dej hiav txwv tsis zoo lossis cov dej hiav txwv kub. Txawm hais tias nws tus nqi siab, stainless hlau tsis ntev ntev ntev kev pabcuam lub neej txo cov kev tu xyuas.
Roj hmab, feem ntau siv rau cov ntsaws ruaj ruaj thiab gaskets, yuav tsum tau elasticity thiab laus tsis kam. High - roj hmab zoo (xws li EPDM) nyob ruaj khov ntawm {degree, kom tau cov dej me me ua ntej xau dej.
Xaiv cov khoom zoo rau cov khoom siv tsav dej yog qhov tseem ceeb rau kev ntsuas kev ua tau zoo, raug nqi, thiab kev hloov kho ib puag ncig. Kev nce qib yav tom ntej hauv cov ntaub ntawv kev kawm txuj ci yuav ntsuas kev txhim kho thev naus laus zis hauv lub teeb ci, ib puag ncig cov ntaub ntawv zoo ib puag ncig.
