Lub valve hluav taws xob yog ib qho khoom siv uas tswj qhov qhib thiab kaw ntawm lub valve los ntawm lub tshuab hluav taws xob. Nws tuaj yeem tsis tsuas paub qhov qhib thiab kaw ua haujlwm, tab sis kuj kho lub valve txoj haujlwm.
Yooj yim muab, lub valve hluav taws xob siv lub tshuab hluav taws xob los tswj lub valve, yog li paub qhov qhib thiab kaw ntawm lub valve. Ib qho hluav taws xob valve feem ntau yog tsim los ntawm hluav taws xob actuator thiab lub valve. Nws tuaj yeem muab faib ua ob ntu, sab sauv yog lub tshuab hluav taws xob, thiab sab qis yog lub valve.
Technical txoj cai
Lub tshuab hluav taws xob hluav taws xob yog lub luag haujlwm rau kev hloov hluav taws xob hluav taws xob rau hauv lub tshuab hluav taws xob kom tsav lub valve hloov lossis kho. Lub tshuab hluav taws xob ntawm lub tshuab hluav taws xob tuaj yeem yog 90 degree quarter-tig lossis linear-tig, thiab cov kev cai tshwj xeeb kuj tuaj yeem ua tau raws li tag nrho cov hlab ntsha ntawm 180 degree, 270 degree, thiab 360 degree. Lub quarter-tig hluav taws xob actuator yog siv nrog lub quarter-tig valve kom paub lub valve tig hauv 90 degree los tswj cov dej ntws ntawm cov kav dej; lub linear-tig hluav taws xob actuator yog siv nrog linear tig valve kom paub qhov nce thiab nqis ntawm lub valve phaj los tswj cov dej ntws ntawm cov kav dej.
Hom yooj yim
Raws li txoj haujlwm valve, nws tuaj yeem muab faib ua: on-off hom hluav taws xob valve thiab modulating hom hluav taws xob valve;
Raws li daim ntawv valve txoj hauj lwm, nws tuaj yeem muab faib ua: hluav taws xob pob valve thiab hluav taws xob npauj npaim valve;
Raws li lub cev lub cev, nws tuaj yeem muab faib ua: lub tshuab hluav taws xob zoo tib yam thiab lub tshuab hluav taws xob micro.
Hluav taws xob li qub feem ntau yog hom on-off, thiab kuj tseem muaj hom modulating, xws li: kiv cua dej inlet yeeb nkab tswj cov dej ntws, thiab lwm yam. On-off hom hluav taws xob li qub feem ntau muab faib ua ib txwm kaw thiab ib txwm qhib hom. Hom kaw feem ntau txhais tau hais tias lub valve nyob rau hauv lub xeev kaw thaum lub hwj chim tawm, thiab ib txwm qhib hom txhais tau hais tias lub valve nyob rau hauv lub xeev qhib thaum lub hwj chim tawm;
