Cov ntsiab lus tseem ceeb ntawm kev teeb tsa thiab kev saib xyuas ntawm Parallel Kev Nyab Xeeb Rov Qab Valve
Mar 10, 2022
Installation thiab txij nkawm ntawm parallel kev nyab xeeb rov qab valve:
1. Lub valve kev nyab xeeb yuav tsum tau nruab vertically ntawm Zui siab txoj hauj lwm ntawm boiler tsum thiab header. Lub qhov hluav taws xob cov yeeb nkab thiab lub valve rau chav yuav tsum tsis txhob ntsia nruab nrab ntawm qhov kev nyab xeeb valve thiab lub nruas lossis header.
2. Lub lever hom kev ruaj ntseg valve yuav tsum tau nruab nrog ib tug ntaus ntawv los tiv thaiv tus kheej txav ntawm cov rauj hnyav thiab ib tug qhia thav duab kom tsis txhob derailment ntawm lub lever. Lub caij nplooj ntoos hlav hom kev ruaj ntseg valve yuav tsum tau nruab nrog ib tug lifting kov thiab ib tug ntaus ntawv los tiv thaiv lub adjustable ntsia hlau los ntawm screwed casually.
3. Rau boilers nrog ntsuas chav siab tsawg dua los yog sib npaug rau 3.82MPa, lub caj pas txoj kab uas hla ntawm kev ruaj ntseg valve yuav tsum tsis pub tsawg tshaj 25 hli; Rau boilers nrog ntsuas chav siab tshaj 3.82MPa, lub caj pas txoj kab uas hla ntawm kev ruaj ntseg valve yuav tsum tsis txhob tsawg tshaj li 20mm.
4. Qhov chaw hla ntawm cov yeeb nkab txuas ntawm qhov kev ruaj ntseg valve thiab lub boiler yuav tsum tsis txhob tsawg tshaj qhov inlet cross-sectional cheeb tsam ntawm kev ruaj ntseg valve. Yog hais tias ob peb qhov kev nyab xeeb li qub tau teeb tsa rau ntawm cov yeeb nkab luv ncaj qha txuas nrog lub nruas, qhov chaw hla ntu ntawm cov yeeb nkab luv yuav tsis yog 1.25 npaug ntawm qhov chaw tso pa ntawm txhua qhov kev nyab xeeb li qub.
5. Feem ntau, qhov kev nyab xeeb valve yuav tsum tau nruab nrog lub tshuab tso pa tawm, uas yuav tsum tau txuas ncaj qha mus rau qhov chaw nyab xeeb thiab muaj qhov chaw seem txaus los xyuas kom meej cov pa tso pa tawm. Hauv qab ntawm cov yeeb nkab tso tawm ntawm qhov kev nyab xeeb valve yuav tsum tau ua txuj ua kom muaj cov kav dej txuas nrog rau qhov chaw nyab xeeb. Valves tsis raug tso cai rau muab tso rau ntawm lub tso pa tawm thiab cov kav dej.
6. Boilers nrog cov ntsuas evaporation muaj peev xwm ntau dua 0.5t / h yuav tsum tau nruab nrog tsawg kawg ob qhov kev nyab xeeb li qub; Boilers nrog cov ntsuas evaporation tsawg dua lossis sib npaug rau 0.5t / h yuav tsum tau nruab nrog tsawg kawg ib lub valve. Kev nyab xeeb li qub yuav tsum tau muab tso rau ntawm qhov hluav taws xob ntawm qhov hluav taws xob sib cais thiab qhov hluav taws xob ntawm chav superheater.
7. Kev nyab xeeb valve ntawm lub nkoj siab yog ncaj qha ntsia ntawm Zui siab txoj hauj lwm ntawm lub siab hlab ntsha lub cev. Kev nyab xeeb valve ntawm liquefied gas cia tank yuav tsum tau muab ntsia rau ntawm cov roj theem txoj hauj lwm. Feem ntau, cov yeeb nkab luv luv tuaj yeem txuas nrog lub thawv, thiab txoj kab uas hla ntawm cov yeeb nkab luv luv ntawm qhov kev nyab xeeb valve yuav tsum tsis txhob tsawg dua li lub valve txoj kab uas hla ntawm kev ruaj ntseg valve.
8. Feem ntau, tsis muaj lub valve yuav tsum tau nruab nruab nrab ntawm qhov kev nyab xeeb valve thiab lub thawv. Rau qhov yooj yim ntawm kev ntxuav lossis hloov qhov kev nyab xeeb valve, lub valve nres tuaj yeem ntsia tau rau lub thawv ntawm cov nplaim hluav taws kub, tawg lossis cov kua nplaum. Lub nres valve yuav tsum qhib tag nrho thiab kaw nrog cov hlau lead thaum lub sijhawm ua haujlwm ib txwm ua kom tsis txhob txav mus los.
9. Rau cov hlab ntsha siab nrog cov nplaim hluav taws, tawg lossis tshuaj lom, cov xov xwm tawm los ntawm lub valve kev nyab xeeb yuav tsum muaj cov cuab yeej kev nyab xeeb thiab cov txheej txheem rov qab. Lub lever kev ruaj ntseg valve yuav tsum tau muab ntsia rau hauv txoj hauj lwm ntsug, thiab lub caij nplooj ntoos hlav kev nyab xeeb valve yuav tsum tau ntsia vertically kom tsis txhob cuam tshuam nws cov kev ua. Thaum lub sij hawm installation, kuj yuav tsum tau them nyiaj mloog mus rau lub haum, lub coaxiality ntawm qhov chaw thiab lub teeb kev nyuaj siab ntawm txhua bolts.
10. Lub tshiab khiv ruaj ntseg valve yuav tsum tau txuas nrog cov khoom pov thawj. Ua ntej kev teeb tsa, nws yuav tsum tau rov ntsuas dua, cov hlau lead kaw thiab muab nrog daim ntawv pov thawj kev ruaj ntseg valve.
11. Lub qhov hluav taws xob ntawm qhov kev nyab xeeb valve yuav tsum tsis muaj kev tiv thaiv thiab tsis txhob rov qab siab. Yog tias cov yeeb nkab tso tawm, nws txoj kab uas hla sab hauv yuav tsum siab tshaj qhov hluav taws xob txoj kab uas hla ntawm qhov kev nyab xeeb valve. Qhov chaw nres nkoj tawm ntawm qhov kev nyab xeeb valve yuav tsum tau them sai sai rau cov tshuaj tiv thaiv. Rau cov thawv ntim khoom uas muaj cov nplaim hluav taws kub, muaj kuab lom thiab muaj kuab lom heev, cov yeeb nkab tawm yuav tsum txuas ncaj qha mus rau qhov chaw nyab xeeb sab nraum zoov lossis muaj cov chaw kho mob kom raug. Tsis muaj valve raug tso cai rau nruab rau hauv cov yeeb nkab tawm.
12. Tsis muaj lub valve yuav tsum tau nruab nruab nrab ntawm cov khoom siv siab thiab kev ruaj ntseg valve. Rau cov thawv ntim khoom uas muaj cov nplaim hluav taws kub, tawg, tshuaj lom lossis cov kua nplaum, cov khoom siv nres tuaj yeem ntsia tau yooj yim hloov thiab ntxuav, thiab lawv cov qauv thiab txoj kab uas hla yuav tsis cuam tshuam rau kev ua haujlwm ntawm kev nyab xeeb valve. Thaum lub sijhawm ua haujlwm ib txwm muaj, qhov nres valve yuav tsum qhib tag nrho thiab kaw nrog cov hlau lead.
