Valves tsis raug tso cai rau muab tso rau ntawm cov pa tso pa tawm los yog 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 uas muaj peev xwm evaporation tsawg dua los yog sib npaug li 0.5t / h yuav tsum tau nruab nrog tsawg kawg yog ib qho kev nyab xeeb valve. Kev nyab xeeb li qub yuav tsum tau muab tso rau ntawm qhov hluav taws xob ntawm lub tshuab hluav taws xob sib cais thiab lub qhov hluav taws xob ntawm chav superheater.
7. Lub tshuab kev nyab xeeb ntawm lub nkoj siab yog qhov zoo tshaj plaws ntsia ncaj qha rau ntawm qhov chaw siab tshaj plaws ntawm lub siab lub cev. Kev nyab xeeb valve ntawm cov roj liquefied gas cia tank yuav tsum tau ntsia rau hauv cov roj theem. Feem ntau, cov yeeb nkab luv luv tuaj yeem siv los txuas rau lub thawv, thiab txoj kab uas hla ntawm cov yeeb nkab luv luv ntawm qhov kev ruaj ntseg valve yuav tsum tsis txhob me dua li txoj kab uas hla ntawm qhov kev ruaj ntseg valve.
8. Cov valve feem ntau tsis tso cai rau nruab nruab nrab ntawm qhov chaw ruaj ntseg li qub thiab ntim khoom. Rau cov thawv nrog cov nplaim taws, tawg lossis cov kua nplaum nplaum, txhawm rau txhawm rau txhim kho kev ntxuav lossis hloov qhov kev nyab xeeb ntawm lub valve, lub valve nres tuaj yeem ntsia tau. Qhov no nres valve yuav tsum tau ntsia thaum lub sij hawm ua hauj lwm ib txwm. Qhib tag nrho thiab kaw kom tsis txhob muaj kev cuam tshuam.
9. Rau cov hlab ntsha siab nrog cov nplaim hluav taws, tawg lossis lom, cov xov xwm tawm los ntawm lub qhov cub kev nyab xeeb yuav tsum muaj cov khoom siv kev nyab xeeb thiab cov txheej txheem rov qab. Kev txhim kho ntawm qhov kev ruaj ntseg valve yuav tsum tuav txoj hauj lwm ntsug, thiab lub caij nplooj ntoos hlav kev ruaj ntseg valve tseem zoo tshaj plaws ntsia tau rau hauv qhov kom tsis txhob cuam tshuam nws qhov kev ua. Thaum lub sij hawm installation, kuj yuav tsum tau them nyiaj mloog mus rau qhov haum, coaxiality ntawm qhov chaw, thiab cov kev ntxhov siab nyob rau hauv txhua tus ntsia liaj qhov rooj.
10. Cov khoom siv hluav taws xob tshiab tshiab yuav tsum tau nrog rau daim ntawv pov thawj khoom. Ua ntej installation, lawv yuav tsum tau recalibrated, kaw thiab muab nrog ib tug ruaj ntseg valve calibration daim ntawv pov thawj.
11. Lub qhov hluav taws xob ntawm qhov chaw ruaj ntseg valve yuav tsum tsis muaj kev tiv thaiv kom tsis txhob rov qab siab. Yog tias cov yeeb nkab tso tawm, nws txoj kab uas hla sab hauv yuav tsum loj dua li qhov hluav taws xob txoj kab uas hla ntawm qhov kev nyab xeeb valve. Lub qhov hluav taws xob tawm ntawm qhov kev nyab xeeb valve yuav tsum tau tiv thaiv los ntawm khov. Nws tsis haum rau lub thawv uas yog flammable los yog tshuaj lom los yog muaj kuab heev. Rau cov khoom ntim tawm, cov yeeb nkab tawm yuav tsum tau txuas ncaj qha mus rau qhov chaw nyab xeeb sab nraum zoov lossis muaj cov chaw pov tseg kom raug. Tsis pub valves rau ntawm cov yeeb nkab tawm.
12. Tsis muaj lub valve yuav tsum tau nruab nruab nrab ntawm cov cuab yeej siv siab thiab lub tshuab hluav taws xob valve. Rau cov thawv ntim cov khoom siv hluav taws xob, tawg, tshuaj lom lossis cov kua nplaum nplaum, txhawm rau txhawm rau hloov thiab ntxuav, lub valve nres yuav raug ntsia, thiab nws cov qauv thiab txoj kab uas hla yuav tsis txawv. Yuav tsum cuam tshuam qhov kev ua haujlwm li qub ntawm kev nyab xeeb valve. Thaum lub sijhawm ua haujlwm ib txwm, qhov nres valve yuav tsum qhib tag nrho thiab kaw.
