Cov txheej txheem kev teeb tsa ntawm cov khoom siv lub rooj vag valve (khoom vaj huam sib luag rooj vag valve) yuav tsum tau xaiv raws li tus qauv tsim, dielectric yam ntxwv thiab daim ntawv thov ntawm cov kav dej tsim. Nws lub hauv paus ntsiab lus yog los xyuas kom meej tias lub foob yog txhim khu kev qha, yoog raws thiab yooj yim los tswj. Cov txheej txheem installation thiab kev ceev faj yog raws li hauv qab no:
1, Kab rov tav installation (feem ntau txoj kev).
Muaj cov xwm txheej
Cov kav dej yog teem rau horizontally nrog lub valve axis parallel rau hauv av.
Haum rau feem ntau cov xov xwm (xws li dej, chav dej, roj, nkev, thiab lwm yam), tshwj xeeb tshaj yog rau kev ua haujlwm uas lub ntiajteb txawj nqus tsis tshua muaj kev cuam tshuam.
Cov ntsiab lus tseem ceeb ntawm installation
Lub cev kev taw qhia: Xyuas kom tseeb tias cov xub ntws ntawm lub valve lub cev nyob rau hauv tib txoj kev raws li qhov nruab nrab (yog tias lub valve muaj cov ntawv qhia ntws).
Kev them nyiaj yug fixation:
Txhim kho cov hlua khi ntawm ob sab ntawm lub raj xa dej kom tiv thaiv kev hloov pauv ntawm lub valve vim muaj kev hloov pauv hauv xov xwm siab lossis kub.
Txhawm rau kom tsis txhob muaj qhov hnyav ntawm lub valve tag nrho los ntawm cov yeeb nkab, tshwj xeeb tshaj yog rau cov caliber loj, cov hlua khi yuav tsum tau teeb tsa.
Chaw ua haujlwm:
Xyuas kom tseeb tias muaj ntau chav rau handwheels, hluav taws xob actuators lossis pneumatic actuators (qhov sib txawv ntawm 1.5 npaug ntawm qhov siab ntawm lub valve feem ntau xav tau).
Yog hais tias lub valve yog hluav taws xob, cable tso qhov chaw thiab kev saib xyuas yuav tsum tau tshwj tseg.
kom zoo dua
Cov dej ntws ntawm cov xov xwm tsis tu ncua, uas txo cov kev cuam tshuam ntawm kev kub ntxhov ntawm lub sealing nto.
Ib qho yooj yim los soj ntsuam valve raws li txoj cai (xws li to, qhib cov lus qhia) thiab kev saib xyuas niaj hnub.
2, Vertical installation ( ntsug installation).
Muaj cov xwm txheej
Cov kav dej yog teem vertically nrog lub ncej perpendicular mus rau hauv av.
Nws yog ib txwm muaj nyob rau hauv cov xwm txheej uas qhov chaw txwv lossis qhov chaw khiav ntawm cov xov xwm yuav tsum tau hloov vertically (piv txwv li, cov kav dej ntawm cov plag tsev, cov khoom siv sib txuas cov kav dej).
Cov ntsiab lus tseem ceeb ntawm installation
Medium flow direction:
Nws yog feem ntau pom zoo tias cov xov xwm ntws tawm hauv qab mus rau sab saum toj ("tsawg nkag, siab") thiab qhov nruab nrab siab siv los pab kev sib khi thiab txo qhov kev pheej hmoo ntawm kev xau.
Yog tias qhov nruab nrab ntws los ntawm sab saum toj mus rau hauv qab, nws yuav tsum tau txiav txim siab seb lub valve sealing tsim puas tuaj yeem tiv taus qhov nruab nrab ntawm lub ntiajteb txawj nqus (piv txwv li, lub qhov rooj muag muag muag yuav deform lub sealing nto vim lub ntiajteb txawj nqus).
Valve qia kev tiv thaiv:
Thaum ntsia vertically, lub qia yuav tsum tau vertically upward kom tsis txhob muaj plua plav los yog impurities accumulating ntawm lub valve qia xov, yog li cuam tshuam qhov yooj ntawm kev khiav hauj lwm.
Yog tias tau teeb tsa sab nraum zoov, yuav tsum tau ntxiv lub tsho los nag lossis lub tsho tiv thaiv kom tiv thaiv cov dej nag.
Txhawb thiab ntxiv dag zog:
Cov kav dej ntsug yuav tsum tau txais kev txhawb nqa hauv qab lub valve txhawm rau tiv thaiv cov kav dej deformation vim lub valve nws tus kheej qhov hnyav lossis kev tshaj tawm siab.
kom zoo dua
Txuag qhov chaw kab rov tav rau ib qho kev sib txuas sib txuas.
Lub ntiajteb txawj nqus ntawm qhov nruab nrab tuaj yeem pab foob (ntawm qhov qis hauv thiab siab tawm) thiab txhim kho kev ntseeg tau ntawm lub foob.
3, Tilt installation (kev ua haujlwm tshwj xeeb).
Muaj cov xwm txheej
Thaum cov yeeb nkab yuav tsum tau teem rau ntawm lub kaum sab xis (xws li tilted yeeb nkab, cov khoom siv txuas cov kav dej, thiab lwm yam), nws tsis tuaj yeem hloov kho kab rov tav lossis ntsug.
Nws feem ntau pom muaj nyob rau hauv cov kav dej sib txuas hauv kev lag luam chemical thiab roj av.
Cov ntsiab lus tseem ceeb ntawm installation
Angular txwv:
Inclination feem ntau tsis ntau tshaj 15 degree, txwv tsis pub qhov kev faib tsis sib npaug ntawm cov quab yuam ntawm lub sealing npog vim tsis sib npaug ntawm qhov nruab nrab lub ntiajteb txawj nqus yuav ua rau to.
Valve qia Kev taw qhia:
Lub qia yuav tsum nyob twj ywm kwv yees li ntsug (ntsia lub kaum sab xis tsawg dua lossis sib npaug li 5 degree) kom ntseeg tau tias kev ua haujlwm zoo ntawm lub tshuab ua haujlwm (xws li lub log, actuator).
Txhim kho kev txhawb nqa:
kev txhawb nqa brackets yog ntxiv rau ntawm ob sab ntawm lub valve thiab hauv qab lub valve kom tiv thaiv kev ntxhov siab hauv cov yeeb nkab vim tilting.
Kev tiv thaiv
Tilting installation accelerates hnav thiab tsim kua muag ntawm lub sealing cover, li no yuav tsum tau kom luv luv lub sij hawm txij nkawm thiab xyuas tsis tu ncua rau cov leaks.
Tsis txhob txhim kho txoj kab uas hla loj cov khoom disc rooj vag valve ntawm inclined yeeb nkab kom txo tau qhov cuam tshuam ntawm dielectric poob siab rau valve stability.
4, General Installation Specifications thiab Daim Ntawv Ceeb Toom.
cov kav dej tu
Ua ntej kev teeb tsa, cov yeeb nkab yuav tsum tau ntxuav kom huv si ntawm cov khib nyiab (xws li solder slag, xeb, xuab zeb hais, thiab lwm yam) txhawm rau tiv thaiv cov impurities los ntawm kev lo rau ntawm qhov chaw sib khi, ua rau lub disc tawg lossis puas.
Cov lim dej ib ntus raug pom zoo ua ntej thiab tom qab kev teeb tsa valve los lim cov teeb meem hauv xov xwm thaum pib ua haujlwm.
Alignment thiab concentric
Xyuas kom meej tias lub valve flange yog ua raws li cov kav dej flange nrog qhov sib txawv tsawg dua lossis sib npaug li 1 hli nyob rau hauv rooj plaub valve lub cev deformation lossis mounting kev ntxhov siab ua rau lub foob tsis ua haujlwm.
Siv tshwj xeeb flange gaskets (xws li hlau qhwv gaskets thiab PTFE gaskets) kom nruj bolts tusyees kom tsis txhob muaj overtightening hauv zos.
Kev txhim kho cov txheej txheem ua haujlwm
Lub handwheel lossis actuator yuav tsum tau kho kom ruaj khov kom tsis txhob xoob thaum ua haujlwm.
Hluav taws xob / pneumatic actuators yuav tsum tau hloov kho raws li cov lus qhia kom ntseeg tau tias qhib cov lus qhia ua raws li qhov tseeb ntawm lub valve.
Kev ntsuas siab thiab kev tshuaj xyuas cov dej xau
Tom qab kev teeb tsa, kev ntsuas siab (feem ntau yog 1.5 npaug ntawm qhov tsim siab) yuav tsum tau kuaj xyuas cov dej ntws tawm thiab kev sib txuas.
Qhov ntsuas nruab nrab yuav tsum ua raws li cov kev ua haujlwm tiag tiag (xws li chav ntsuas qhov ntsuas ntawm cov kav dej kom tsis txhob muaj kev kub ntxhov los ntawm dej).
