Vim tias qhov txav ntawm npauj npaim valve phaj yog so, feem ntau npauj npaim li qub tuaj yeem siv rau kev tshaj tawm nrog cov khoom raug tshem tawm, thiab tseem tuaj yeem siv rau cov hmoov thiab granular media nyob ntawm lub zog ntawm lub foob.
Cov qauv ntev thiab tag nrho qhov siab ntawm npauj npaim valve yog me me, thiab qhov qhib thiab kaw nrawm nrawm. Thaum nws qhib tag nrho, nws muaj cov kua dej me me. Thaum nws qhib rau li 15 degree mus rau 70 degree, nws kuj tuaj yeem ua qhov kev tswj xyuas qhov dej ntws. Npauj npaim valve Lub hauv paus ntsiab lus yog qhov tsim nyog tshaj plaws rau kev ua qhov loj-inch li qub.
Npauj npaim valve raug pom zoo raws li cov hauv qab no ua haujlwm:
① Nws yuav tsum tau throttle thiab kho cov tswj ntws;
② Slurry nruab nrab thiab nruab nrab uas muaj cov khoom siv;
③ Thaum qhov ntev ntawm cov qauv valve yuav tsum yog luv;
④ Lub sijhawm qhib thiab kaw nrawm;
⑤ Thaum lub siab sib txawv me me.
Npauj npaim valve yuav siv tau nyob rau hauv ob txoj hauj lwm hloov, nqaim channel, tsis tshua muaj suab nrov, cavitation thiab gasification, ib tug me me npaum li cas ntawm to atmospheric cua, thiab abrasive nruab nrab.
Thaum lub npauj npaim valve siv nyob rau hauv tshwj xeeb kev ua hauj lwm xws li throttling hloov los yog nruj sealing yuav tsum tau, los yog hnyav hnyav, tsis tshua muaj kub (cryogenic) thiab lwm yam kev ua hauj lwm, nws yog tsim nyog los siv ib tug tshwj xeeb tsim ntawm triple eccentric los yog ob chav eccentric tshwj xeeb npauj npaim valve. nrog hlau foob nrog kev hloov khoom siv.
Lub teeb liab npauj npaim valve yog tsav los ntawm cov cab iav thiab cov cab cab kom tig lub ncej thiab lub phaj npauj npaim kom qhib thiab kaw thiab tswj qhov ntws. Tig lub handwheel ntawm cov cab iav kis tau tus mob kom ua kom lub phaj npauj npaim ua tiav lub hom phiaj ntawm kev qhib thiab kaw thiab kho qhov ntws. Lub handwheel yog tig clockwise kom kaw lub valve.
siv ntaus ntawv
Txuas cov tub ntxhais hlau ntawm lub cable mus rau lub davhlau ya nyob twg raws li cov kev cai tswj hluav taws xob, kaw lub cable inlet, thiab kho lub cable tib lub sij hawm kom tsis txhob muaj kev puas tsuaj rau kev sib txuas ntawm cable thaum muaj kev cuam tshuam sab nraud. Thaum lub valve nyob rau hauv "tag nrho kaw" txoj hauj lwm, tig lub qis kaw cam clockwise los yog lub sab sauv qhib cam counterclockwise. Thaum npauj npaim valve clamps lub raj xa dej, ua tib zoo saib seb qhov kev sib txuas quab yuam puas zoo ib yam thiab txhim khu kev qha. Tom qab lub npauj npaim valve tau teeb tsa, lub phaj valve yuav tsum nyob rau hauv txoj haujlwm qhib thaum lub zog ntawm cov kav dej raug kuaj. Tom qab lub npauj npaim valve tau teeb tsa, nws yuav tsum tau kuaj xyuas tsis tu ncua. Cov khoom soj ntsuam tseem ceeb yog raws li nram no: seb lub rooj npauj npaim valve thiab O-ring foob puas puas. Lub sealing kev ua tau zoo ntawm lub valve phaj sealing nto. Tom qab lub npauj npaim valve tau kho thiab sib sau ua ke, yuav tsum tsis muaj qhov tshwm sim thaum qhib thiab kaw. Tom qab lub npauj npaim valve tau kho thiab sib sau ua ke, kev ntsuas kev sib khi yuav tsum tau ua raws li qhov xav tau.
