QB series Part-tig hluav taws xob valve actuator yog siv rau li qub nrog ib feem-tig discs, xws li pob li qub, npauj npaim li qub, dampers, thiab lwm yam. Lub tuam txhab ib feem-tig tawg-pov thawj hluav taws xob valve actuator muab faib ua ob yam khoom, QB thiab DQ. Lub zog torque ntawm QB series yog: 125-4000Nm (hom tswj yog 50-2000Nm); torque ntau ntawm DQ series 2000-250000Nm (4000-16000Nm rau hom tswj); ob cov khoom no tau muab faib ua peb hom: hom zoo tib yam, ib hom thiab tswj hom raws li cov kev tswj hluav taws xob sib txawv. Cov hluav taws xob tawg-pov thawj hluav taws xob valve actuator muaj built-in hauv paus tswj chav xws li mob stroke thiab torque, thiab lub thawv tswj yuav tsum tau paub txog qhov chaw thiab chaw taws teeb tswj ntawm lub valve. Cov ntsuas ntsuas ua tau raws li qhov yuav tsum tau ua ntawm GB / T 24922-2010 "Technical Conditions for explosion-proof electric valve actuators". Ntxiv nrog rau cov kev tswj hwm yooj yim xws li cov kab mob stroke thiab lub zog ua haujlwm, cov khoom siv hluav taws xob tawg-pov thawj hluav taws xob valve actuator kuj tau nruab nrog cov khoom tswj xws li tswj modules thiab AC contactors. Nws tuaj yeem txuas ncaj qha rau cov khoom siv hluav taws xob kom paub txog qhov chaw ua haujlwm ntawm lub valve, thiab tuaj yeem tau txais DCS tswj ncaj qha. Lub switching teeb liab tso zis los ntawm lub system paub qhov chaw taws teeb tswj kev khiav hauj lwm ntawm lub valve. Cov ntsuas kev ua tau zoo ua tau raws li qhov yuav tsum tau ua ntawm GB / T 24922-2010 "Technical Conditions for explosion-proof electric valve actuators". Kev tawg-pov thawj adjustable hluav taws xob valve actuator yog tsim rau lub kaw-voj tswj system ntawm cov txheej txheem kev lag luam, thiab tuaj yeem ua qhov tseeb ntawm lub valve los ntawm kev txais 4-40mA tam sim no teeb liab xa los ntawm kev tswj hwm. Cov ntsuas kev ua tau zoo ua tau raws li qhov yuav tsum tau ua ntawm GB/T24922-2010 "Technical Conditions for explosion-proof electric valve actuators" thiab JB/T8219-2016 "Common and Intelligent Electric Actuators for Industrial Process Control Systems".
