Pneumatic valve actuators feem ntau yog siv nyob rau hauv nuclear fais fab nroj tsuag los yog fais fab nroj tsuag vim hais tias ib tug ruaj khov, du thiab qeeb txheej txheem yuav tsum tau nyob rau hauv cov dej siab. Qhov zoo ntawm cov hluav taws xob actuators yog kev ruaj ntseg siab thiab ruaj khov thrust uas tuaj yeem siv los ntawm cov neeg siv khoom. Tsuas yog hydraulic actuators tuaj yeem ua tiav qhov kev sib tw loj, tab sis tus nqi ntawm hydraulic actuators ntau dua li cov hluav taws xob. Lub peev xwm los tiv thaiv kev sib txawv ntawm lub tshuab hluav taws xob yog qhov zoo heev, qhov tso zis tawm los yog lub zog yog qhov ruaj khov, nws tuaj yeem kov yeej qhov tsis sib npaug ntawm qhov nruab nrab, thiab ua tiav qhov kev tswj hwm ntawm cov txheej txheem tsis raug, yog li kev tswj xyuas qhov tseeb yog siab dua. uas yog pneumatic actuator. siab. Yog tias nws tau nruab nrog lub tshuab hluav taws xob servo, nws tuaj yeem paub qhov sib pauv ntawm qhov zoo thiab qhov tsis zoo, thiab tseem tuaj yeem yooj yim teeb tsa lub xeev ntawm lub teeb liab valve txoj hauj lwm (tsis tu ncua / qhib / puv kaw), thiab thaum nws ua tsis tiav, nws yuav tsum nyob rau hauv thawj txoj hauj lwm, uas yog pneumatic Lub actuator tsis tuaj yeem ua nws, thiab pneumatic actuator yuav tsum siv lub tshuab ua ke ua ke kom nws nyob hauv qhov chaw.
Lub ntsiab tsis zoo ntawm hluav taws xob actuators yog:
Cov qauv yog qhov nyuaj dua, thiab nws yooj yim dua los ua tsis tiav, thiab vim nws txoj haujlwm nyuaj, cov txheej txheem kev cai rau cov neeg ua haujlwm saib xyuas ntawm qhov chaw yog qhov siab dua; kev ua haujlwm ntawm lub cev muaj zog yuav tsim kom muaj cua sov, yog tias qhov kev hloov kho ntau dhau lawm, nws yuav yooj yim ua rau lub cev muaj zog thiab ua kom muaj cua sov. Nws tseem yuav ua rau kom hnav ntawm cov iav txo qis; kuj tseem muaj kev ua haujlwm qeeb, uas yuav siv sijhawm ntev los tso tawm cov teeb liab los ntawm tus tswj hwm mus rau qhov sib thooj ntawm cov tswj valve, uas tsis zoo li pneumatic thiab hydraulic execution. qhov chaw ntawm lub cuab yeej.
Lub actuator thiab regulator ntawm lub valve pneumatic actuator yog tib yam nkaus, thiab cov actuators muaj ob hom: diaphragm hom thiab piston hom. Hom piston yog tsim rau lub sijhawm uas yuav tsum muaj lub zog loj vim nws txoj hlab ntsha ntev; thaum lub diaphragm hom muaj ib tug me me stroke thiab tsuas yog ncaj qha tsav lub valve qia. Vim hais tias pneumatic actuators muaj qhov zoo ntawm cov qauv yooj yim, ruaj khov thiab txhim khu kev qha, cov khoom tso tawm loj, thiab kev nyab xeeb thiab tawg-pov thawj, lawv tau siv dav hauv tshuaj, hluav taws xob cog, roj refining thiab lwm cov txheej txheem ntau lawm nrog kev ruaj ntseg siab.
Cov txiaj ntsig tseem ceeb ntawm pneumatic actuators: lawv tuaj yeem lees txais cov pa hluav taws xob txuas ntxiv, tso tawm tawm qhov hloov pauv, thiab qee qhov tuaj yeem tso tawm qhov kev hloov pauv tom qab tau nruab nrog lub caj npab rocker; lawv muaj qhov zoo thiab qhov tsis zoo; qhov txav ceev yog loj, tab sis qhov ceev yuav hloov thaum lub load nce qeeb; lub zog tso zis muaj feem xyuam rau kev khiav hauj lwm siab; qhov kev ntseeg siab yog siab, tab sis lub valve tsis tuaj yeem khaws cia tom qab qhov chaw huab cua cuam tshuam; Kev tawg-pov thawj muaj nuj nqi.
Cov saum toj no yog cov ntsiab lus hais txog kev sib piv ntawm qhov zoo thiab qhov tsis zoo ntawm cov hluav taws xob li qub thiab pneumatic li qub. Piv txwv tias koj muaj kev thov rau peb lub tuam txhab cov khoom, txais tos hu rau cov neeg siv khoom hauv online los nug txog cov lus hais thiab lwm yam ntaub ntawv. Koj tseem txais tos tuaj rau peb lub tuam txhab rau kev nug thiab ua tsaug caw koj los koom tes. !
