Yuav ua li cas xaiv Npauj Npaim Valve?

Npauj Npaim ValveXaiv: Yuav ua li cas xaiv ntawm Mos Foob thiab Lub Pob Tsuas?

Nyob rau hauv kev xaiv Npauj Npaim li qub, qhov kev xaiv ntawm cov ntaub muag mos mos mos ntawm cov npauj npaim li qub thiab lub neej sib khi ua haujlwm, thiab tus nqi. Cov tub ntxhais sib txawv ntawm ob tug lus dag hauv cov khoom siv sealing thiab muaj feem cuam tshuam los ntawm peb yam: cov yam ntxwv nruab nrab, thiab lub siab thiab qhib zaus.

Lub khub sib khi ntawm cov muag muagNpauj Npaim Li QubFeem ntau siv roj hmab (xws li cov roj hmab nitrile, EPDM roj hmab) lossis fluoroploast (xws li PTFE), uas muaj qhov zoo ntawm xoom tuav thiab qis qhib thiab kaw lub zog. Thaum lub nruab nrab yog chav sov huv, roj lossis qaug zog corrosive (xws li lub tshuab nqus dej nyob rau hauv, xws li cov kav dej sib tw ua ke nrog cov kav dej ua kom nruj Txawm li cas los xij, nws yuav tsum tau sau tseg tias cov kev txwv sab sauv ntawm qhov kub tsis kam rau roj hmab yog 120 ℃, thiab rau fluoroplastics nws yog 180 ℃. Tshaj li cov no ntau yuav ua rau kev sib khi saum npoo kom tawv lossis deform, coj mus toffage.

Harded Npauj Npaim li qub thiab kev kub siab tsis kam los ntawm cov hlau (xws li hlau stainless, nyuaj alloy) rau hlau lossis hlau rau ceramic sib khi ua khub. Nyob rau hauv cov kev ua haujlwm ntawm chav dej, thermal roj, muaj cov nplais ntawm lub zog (xws li cov kev pab cuam sab nrauv (yoov, thiab kev pabcuam lub neej yog 3-5 zaug uas yog tus muag muag. Piv txwv li, ob chav eccentric HARTED Npauj Npaim li qub li qub yog siv nyob rau hauv boiler Feederwater kav hauv lub zog kev lag luam. Lawv cov qauv eccentric tuaj yeem txo cov kev sib txhuam ntawm cov chaw sib khi, thaum sib npaug ntawm qhov kub thiab qhib thiab kaw thiab kaw thiab kaw cov khoom siv kub.

Muaj ob qhov kev tsis paub tseeb los kom paub txog thaum xaiv ib qho khoom lag luam: ua ntej, ib qho yuav tsum tsis txhob dig muag rau txoj hlua dig muag. Yog tias tsis muaj qhov kub tshaj plaws hauv nruab nrab, tus nqi siab thiab loj dua thiab qhib lub zog thiab kaw cov npauj npaim nyuaj ua tsis zoo; Thib ob, Seetered Npauj Npaim li qub ≠ qhov kev ntsuam xyuas qis qis. Los ntawm thickening lub cev valve thiab ntxiv dag zog rau cov qauv sib khi, qee cov ntaub ntawv muag muag npauj npaim)

Xaus: Qhov muag muag muagNpauj Npaim Li QubYog xav tau rau chav tsev ntxhua khaub ncaws tu kom zoo nkauj Yog tias cov haujlwm ua haujlwm nyob nruab nrab ntawm ob (xws li dej kub ntawm 150 ℃), ib qho hluav taws xob hluav taws xob sib xyaw nrog kev sib npaug nrog kev sib npaug ntawm kev ua tau zoo thiab raug nqi.
