Cov Kev Xaiv Logic ntawm Lub Valve Stem Hauv Qab Kub Siab thiab Kub Siab

Hauv cov qauv ntawm lub valve, lub valve qia tsis zoo li nyuaj, tab sis tsuav yog koj tau khiav los ntawm qhov kub thiab txias siab thiab lub tshuab siab, koj paub tias nws yog ib qho ntawm cov teeb meem feem ntau. Tshwj xeeb tshaj yog nyob rau hauv cov chaw tsim hluav taws xob, kev ua kom huv thiab metallurgy, qhov twg qhov kub ntawm qhov nruab nrab feem ntau yog plaub lossis tsib puas degrees thiab qhov siab yog kaum tawm kilograms, yog tias lub valve qia tsis raug xaiv tsim nyog, lub foob yuav tsis ua haujlwm tsawg kawg, thiab nws yuav raug tawg ncaj qha lossis daig.

Peb tau ntsib ib qho teeb meem tiag tiag: ib pawg ntawm cov qhov dej hauv lub ntiaj teb siv hauv chaw tsim hluav taws xob pib jam ntau zaus tom qab ib nrab xyoo ntawm kev ua haujlwm, thiab qhov kev rhuav tshem ntawm qhov chaw pom tias qhov chaw ntawm lub qhov dej tau ploj xim thiab distorted, thiab cov sealing packing tsis tuaj yeem raug suppressed. Tom qab ntawd, nws tau lees paub tias tus qauv tsim thawj zaug yog ua los ntawm 304 stainless hlau, tab sis qhov kub ua haujlwm ntawm cov kav dej yog ze li ntawm 500 ° C, thiab cov khoom siv tau dhau qhov txwv.

Qhov ua rau lub qia tsis ua haujlwm ntawm qhov kub thiab txias thiab siab siab tsis yog tsuas yog tsis muaj zog ntawm cov khoom siv xwb, tab sis kuj yog qhov hloov pauv ntawm qhov loj me vim yog kev nthuav dav thermal, kev tawg qaug zog los ntawm kev ntxhov siab thermal, thiab kev sib txhuam qhuav los ntawm kev ua tsis tiav ntawm cov roj nplua nyeem. Tshwj xeeb tshaj yog thaum siv ntau zaus qhib thiab kaw, mob stroke ntev, thiab thauj khoom ntau, qhov sib tshooj ntawm cov yam no yuav ua rau lub neej ntawm lub qia valve luv luv heev.

Yog li ntawd, peb feem ntau tsom mus rau ntau yam thaum xaiv: ua ntej, sim siv cov ntaub ntawv uas muaj qhov kub thiab txias thiab ruaj khov, xws li 17-4PH, F6a, 1Cr13Mo thiab lwm yam hlau alloy siab, yog tias nws yog cov kua qaub nruab nrab, duplex stainless hlau lossis Monel alloy yuav tsum tau xav txog; Qhov thib ob, nws raug pom zoo kom muab cov txheej cemented carbide rau qhov txuas threaded kom txhim kho lub peev xwm tiv thaiv kev ntes; Qhov thib peb, thaj chaw tiv tauj ntawm cov khoom sau yuav tsum tau ua kom raug thiab nitrided lossis coated.

Tsis tas li ntawd xwb, nws raug pom zoo kom siv cov txheej txheem sib xyaw ua ke es tsis txhob siv cov qauv txuas welded kom ntau li ntau tau kom txo qhov kev pheej hmoo ntawm kev ua tsis tiav ntawm qhov interface. Hauv cov ntawv thov ntev, nws yog qhov tsim nyog los suav nrog qhov axial offset los ntawm thermal deformation, txwv tsis pub yuav muaj teeb meem "tsis nyob hauv qhov chaw" lossis "tacked".

Lub valve stem uas tsim los ntawm Yining Machinery tam sim no siv dav hauv petrochemical, hluav taws xob, metallurgy, liquefied gas thiab lwm yam lag luam, peb tau tsim tshwj xeeb tsim cov valve stems tsim rau ntau yam kev sib txuas rau qhov kub thiab txias siab, suav nrog kev forging finishing, thread surfacing welding, iav kho thiab lwm yam txheej txheem, uas tuaj yeem daws cov kev xav tau ua haujlwm ntawm kev thauj khoom siab thiab kev qhib thiab kaw zaus.

Hauv kev xaus, txawm hais tias cov qauv qia yooj yim, nyob rau hauv qhov kub thiab txias siab, thaum xaiv tsis raug yog "qhov tsis muaj zog" ntawm lub kaw lus. Nws raug pom zoo tias nyob rau theem tsim thiab kev yuav khoom, kev suav nyiaj kom ntxaws yuav tsum tau ua ua ke nrog cov kev ua haujlwm, kev qhib thiab kaw, thiab zaus siv, es tsis txhob tsuas yog saib cov ntaub ntawv kos duab lossis tus nqi los txiav txim siab qhov kev xaiv.
