Txhua lub tshuab hluav taws xob yuav tsum tau nruab nrog tsawg kawg 2 qhov kev nyab xeeb li qub nrog kev hloov pauv txaus. Qhov kev nyab xeeb valve yog qhov qhib thiab kaw qhov chaw uas nyob rau hauv ib txwm kaw lub xeev raws li qhov kev txiav txim ntawm sab nraud quab yuam. Thaum qhov nruab nrab siab nyob rau hauv cov khoom siv los yog cov kav dej nce siab tshaj tus nqi teev, qhov kev nyab xeeb valve dhau los ntawm Ib qho tshwj xeeb valve uas tso tawm qhov nruab nrab tawm ntawm qhov system los tiv thaiv lub siab ntawm qhov nruab nrab hauv cov raj xa dej los yog cov khoom siv los ntawm kev tshaj li tus nqi teev tseg.
Kev nyab xeeb li qub yog tsis siv neeg li qub thiab feem ntau yog siv rau hauv boilers, chav generators, siab hlab ntsha thiab kav dej los tswj lub siab tsis pub tshaj tus nqi teev. Raws li ib feem tseem ceeb ntawm chav boilers, kev nyab xeeb li qub muaj cov cai nruj rau kev teeb tsa. Qhov no kuj yog los xyuas kom meej tias qhov cub Lub hauv paus rau kev ua haujlwm ntawm lub tshuab hluav taws xob.
Raws li cov qauv ntawm kev ruaj ntseg valve, nws tau muab faib ua hnyav rauj qib kev nyab xeeb valve, lub caij nplooj ntoos hlav micro-lift kev nyab xeeb valve thiab mem tes kev nyab xeeb valve. Raws li kev ua raws li cov kev cai ntawm kev ruaj ntseg valve installation, xyuam xim rau cov ntsiab lus kom tsis txhob muaj kev phiv los ntawm cov txheej txheem ua haujlwm. .
Ua ntej,lub installation txoj hauj lwm ntawm kev ruaj ntseg valve feem ntau yog ntsia rau saum lub tshuab hluav taws xob, tab sis nws yuav tsum tsis txhob nruab nrog lub qhov hluav taws xob kav thiab li qub rau noj chav. Yog hais tias nws yog ib tug lever-type kev ruaj ntseg valve, nws yuav tsum tau nruab nrog ib tug ntaus ntawv los tiv thaiv lub luj ntawm txav los ntawm nws tus kheej thiab ib tug qhia kom txo tau lub deviation ntawm lub lever.
Thib ob,tus naj npawb ntawm kev ruaj ntseg li qub ntsia. Rau cov tshuab hluav taws xob nrog lub peev xwm evaporation> 0.5t / h, tsawg kawg yog ob qhov kev nyab xeeb li qub yuav tsum tau teeb tsa; rau cov tshuab hluav taws xob nrog cov ntsuas evaporation muaj peev xwm ≤0.5t / h, tsawg kawg yog ib qho kev nyab xeeb valve yuav tsum tau nruab. Tsis tas li ntawd, cov lus qhia tshwj xeeb ntawm lub tshuab hluav taws xob hluav taws xob muaj kev nyab xeeb yog ncaj qha ntsig txog kev ua haujlwm ntawm lub tshuab hluav taws xob. Yog hais tias qhov ntsuas chav siab ntawm lub tshuab hluav taws xob yog ≤3.82MPa, lub qhov taub ntawm qhov kev ruaj ntseg valve yuav tsum tsis txhob yog <25mm; thiab rau boilers nrog ntsuas chav siab> 3.82MPa, lub orifice txoj kab uas hla ntawm qhov kev ruaj ntseg valve yuav tsum tsis txhob <20mm.
Ntxiv rau,qhov kev nyab xeeb valve feem ntau yog nruab nrog cov yeeb nkab tso tawm, thiab cov yeeb nkab tso tawm yog coj mus rau qhov chaw muaj kev nyab xeeb, thaum tawm hauv qhov chaw seem txaus los xyuas kom meej qhov ntws ntawm cov pa tawm thiab muab tag nrho ua si rau lub luag haujlwm ntawm kev nyab xeeb valve. Kev ua haujlwm ntawm lub tshuab hluav taws xob hluav taws xob kev nyab xeeb valve: txhawm rau xyuas kom meej tias lub tshuab hluav taws xob tsis ua haujlwm nyob rau hauv lub xeev overpressure. Ntawd yog, thaum lub sijhawm ua haujlwm ntawm lub tshuab hluav taws xob, yog tias lub siab tshaj qhov kev ua haujlwm siab, lub valve kev nyab xeeb yuav mus los kom txo tau lub tshuab hluav taws xob los ntawm kev tso pa tawm. Kev ua haujlwm ntawm lub siab tiv thaiv lub tshuab hluav taws xob tawg thiab lwm yam xwm txheej vim yog overpressure.
Nobeth chav tshuab hluav taws xob siv cov khoom siv hluav taws xob zoo tshaj plaws nrog kev ua haujlwm zoo, kev tsim qauv tsim, tsim qhov chaw tsim nyog, kev ua haujlwm zoo, thiab kev ua haujlwm nruj raws li cov qauv. Nws tau raug sim ntau zaus ua ntej tawm hauv lub Hoobkas kom ntseeg tau tias muaj kev nyab xeeb ntawm lub tshuab hluav taws xob lub tshuab hluav taws xob, vim tias nws yog ib qho tseem ceeb ntawm txoj kab cawm neeg txoj sia rau lub tshuab hluav taws xob thiab tseem yog txoj kab cawm txoj sia rau kev nyab xeeb ntawm tus kheej.
