Cov Cheebtsam Valve Tshwj Xeeb: Cov Kev daws teeb meem rau cov teeb meem ntawm lub kaw lus lag luam

Hauv cov xwm txheej kev saib xyuas uas siv tau thoob plaws hauv cov txheej txheem lag luam, qhov ua tsis tiav ntawm cov tshuab valve tsis tshua muaj vim yog lub cev valve nws tus kheej. Hloov chaw, nws feem ntau yog cov khoom sab hauv - cov qia valve raug kev puas tsuaj los ntawm kev hnav ntawm qhov chaw, cov rooj zaum valve poob qhov sib koom ua ke hauv qab lub voj voog siab, lossis cov qog ntim khoom tawg vim yog kev qaug zog thermal - uas ua rau lub kaw lus tsis ruaj khov, xau, lossis kaw tsis tau teem sijhawm.

Yog li ntawd, qhov kev thov rau cov khoom siv valve tshwj xeeb tau nce ntxiv tas li. Ib txoj hauv kev uas siv tau rau txhua yam tsis zoo rau cov chaw xws li kev ua tshuaj lom neeg, metallurgy, lossis kev tsim hluav taws xob, qhov twg cov txheej txheem, siab, thiab qhov kub sib txawv ntau heev. Cov khoom siv valve uas tsim tshwj xeeb tau dhau los ua qhov tseem ceeb rau kev ntseeg tau, tshwj xeeb tshaj yog nyob rau hauv cov kab ke uas khiav kev ua haujlwm tas mus li nrog kev zam tsawg kawg rau lub sijhawm tsis ua haujlwm.

Cov kws ua haujlwm hauv thaj teb thiab cov thawj coj saib xyuas kev kho yog tig mus rau cov chaw tsim khoom tshwj xeeb uas tuaj yeem tsim cov khoom raws li qhov kev qhia tshwj xeeb, raws li cov duab kos lossis cov qauv kuaj. Ntawm Sichuan Yining Machinery, peb ib txwm siv tshuab valve stems, couplings, seats, thiab actuator mounting brackets uas tsim los rau cov kev xav tau tshwj xeeb ntawm kev siv tshuab thiab ib puag ncig. Txawm hais tias nws yog A105 carbon steel nrog kev txo kev ntxhov siab tom qab kev siv tshuab lossis CF8M stainless hlau kho rau kev tiv thaiv corrosion, txhua txoj haujlwm yog coj los ntawm kev paub txog cov txheej txheem, tsis yog kev xav.

Kev xaiv cov khoom siv tsis yog ib qho kev tawm dag zog uas yuav tsum tau ua tib zoo xav. Nws yog raws li cov txheej txheem hnav, qhov kub thiab txias, thiab kev sib haum xeeb ntawm cov tshuaj lom neeg. Piv txwv li, cov kav dej ua haujlwm siab rau cov twj tso kua mis yuav tau txais txiaj ntsig los ntawm cov khoom siv tawv 17-4PH lossis nitrided 410 stainless, thaum cov rooj zaum hauv kev pabcuam slurry feem ntau xav tau Stellite overlays lossis precision polishing kom tswj tau qhov sealing hauv qab cov dej ntws abrasive.

Peb tau pom cov xwm txheej tiag tiag uas qhov mounting qhov ntawm lub bracket deviated los ntawm 0.5 hli thiab ua rau actuator misalignment, lossis qhov twg lub valve pob tsis tau kaw vim tias qhov puag ncig ntawm qhov chaw poob sab nraum 0.01 hli kev kam rau siab. Cov no tsis yog cov teeb meem theoretical - lawv yog cov teeb meem ua haujlwm uas cov pab pawg cog ua haujlwm kom tshem tawm. Yog vim li cas qhov tseeb thiab haum tseem ceeb npaum li cov khoom siv.

Qhov tseem ceeb tshaj, txhua qhov kev ua haujlwm ntawm peb lub chaw ua haujlwm yog ua raws li kev tswj hwm cov txheej txheem, nrog rau kev taug qab cov khoom siv, cov txheej txheem txiav, thiab cov ntaub ntawv tshuaj xyuas. Peb pab neeg ua haujlwm sib koom tes nrog cov kws ua haujlwm sab nraud los txheeb xyuas cov khoom sib dhos, cov nplaim sealing, thiab cov qauv ruaj khov - tshwj xeeb tshaj yog rau cov khoom thauj lossis cov khoom uas raug kev ntxhov siab ntau.

Xaus lus, qhov kev ntseeg tau ntawm lub valve nyob ntawm qhov ua tau zoo ntawm nws cov khoom sab hauv. Ib qho khoom siv uas tau tsim los ntawm kev ua haujlwm zoo, phim kom raug rau nws qhov chaw ua haujlwm, tuaj yeem ua qhov sib txawv ntawm kev ua haujlwm ruaj khov thiab kev ua tsis tiav kim. Kev hloov kho tsis yog qhov xaiv tau lawm - nws yog qhov tsim nyog hauv cov txheej txheem tswj dej niaj hnub.
