Valve ya Actuator ndi valavu yokhala ndi actuator yolumikizidwa, yomwe imatha kuwongolera valavu pogwiritsa ntchito zizindikiro zamagetsi, zizindikiro za mpweya, ndi zina zotero. Imapangidwa ndi thupi la valavu, diski ya valavu, tsinde la valavu, actuator, chizindikiro cha malo ndi zigawo zina.
Choyatsira magetsi ndi gawo lofunika kwambiri la choyatsira magetsi. Tisanamvetse valavu ya choyatsira magetsi, tiyenera kudziwa kaye choyatsira magetsi.
Kodi Actuator ndi chiyani?
Tanthauzo la Actuator
Actuator ndi gawo lofunika kwambiri la zida zowongolera zokha. Apa pali kufotokozera mwatsatanetsatane kwa actuators.
Kodi Mtundu wa Actuators ndi Chiyani?
Ma actuator amatha kugawidwa m'magulu atatu malinga ndi mtundu wawo wa mphamvu: pneumatic, hydraulic, ndi electric.
Actuator yamagetsi
Choyatsira magetsi chili ndi mota ndi njira yosinthira mkati. Motoka imasintha kayendedwe kozungulira kukhala kayendedwe kolunjika kudzera mu giya, kukankhira tsinde la valavu mmwamba ndi pansi, potero imayang'anira kuchuluka kwa kutseguka ndi kuchuluka kwa kayendedwe ka valavu.
Ma actuator amagetsi ali ndi ubwino wokhala ndi kapangidwe kakang'ono, kugwiritsa ntchito mosavuta, kulondola kwambiri, ndipo ndi osavuta kuphatikiza ndi makina owongolera makompyuta kuti akwaniritse zowongolera zakutali komanso zowongolera zokha.
Ma Actuator a Pneumatic
Ma actuator a pneumatic ndi mtundu wina wodziwika bwino wa ma actuator omwe amalandira zizindikiro za pneumatic ndikusintha kukhala kayendedwe ka makina.
Ma actuator a pneumatic amagwiritsidwa ntchito kwambiri mu ma valve owongolera mpweya m'mafakitale. Amalandira zizindikiro zowongolera za 20 \ ~ 100kPa ndipo amayendetsa ma valve kuti atsegule, atseke kapena asinthe. Ma actuator a pneumatic ali ndi ubwino wa liwiro loyankha mwachangu, kudalirika kwambiri komanso kukonza kosavuta. Ndi oyenera makamaka pazochitika zomwe zimafuna kuyankha mwachangu komanso kuwongolera kokhazikika.
Zoyeserera za Hydraulic
Ma hydraulic actuators amatumiza mphamvu kudzera mu dongosolo la hydraulic. Siteshoni ya hydraulic imapereka mafuta opanikizika, omwe amatumizidwa ku actuator kudzera mu payipi yamafuta kuti ayendetse valavu kapena zida zina zamakaniko. Ma hydraulic actuators nthawi zambiri amakhala ndi ma electro-hydraulic servo valves, omwe amatha kukwaniritsa kulamulira bwino malo ndikuwongolera mphamvu.
Ma hydraulic actuator ndi oyenera nthawi zomwe zimafuna kugwedezeka kwakukulu kapena mphamvu yayikulu, monga kulamulira ma valve akuluakulu, kuyendetsa makina olemera ndi zida, ndi zina zotero. Chifukwa cha kugwedezeka kwakukulu komanso kukhazikika kwakukulu, ma hydraulic actuator nthawi zambiri amagwiritsidwa ntchito m'mafakitale omwe amafunikira kudalirika kwambiri komanso kugwedezeka kwakukulu.
Titadziwa bwino za ma actuator, tiyeni tiphunzire za chidziwitso chofunikira cha ma valve a actuator.
Tanthauzo ndi Ntchito ya Ma Valves a Actuator
Valavu yoyendetsera ntchito imasintha yokha momwe valavu imatsegukira ndi kutsekera polandira zizindikiro zowongolera zakunja, motero imapangitsa kuti pakhale kuwongolera kolondola kwa magawo monga kuyenda, kuthamanga, ndi kutentha. Imagwiritsidwa ntchito kwambiri m'makina owongolera odziyimira pawokha amakampani kuti iwonjezere magwiridwe antchito komanso chitetezo cha kupanga.
Ma valve a actuator amatha kugawidwa m'magulu atatu malinga ndi njira zosiyanasiyana zoyendetsera: ma valve a actuator a pneumatic, ma valve a hydraulic actuator, ndima valve amagetsi oyendetsera magetsi.
Ma Valves a Pneumatic Actuator
Ma valve a pneumatic actuator ndi ma valve oyendetsedwa ndi ma actuator a pneumatic. Ndi zipangizo zoyendetsera kutsegula ndi kutseka ma valve a pneumatic series angle-stroke mongaMa Vavu a Mpira wa Pneumatic, Ma Vavu a Gulugufe a Pneumatic, Ma Valves a Chipata cha Pneumatic, Ma Valves a Pneumatic Globe, ma valve a pneumatic diaphragm, ndi ma valve owongolera pneumatic. Ndi zipangizo zabwino kwambiri zogwirira ntchito yoyang'anira mapaipi odziyimira pawokha kapena oyendetsedwa ndi makampani.
Ma Vavulovu a Actuator amagetsi
Ma valve amagetsi oyendetsera magetsi ndi ma valve oyendetsedwa ndi ma actuator amagetsi. Amagawidwa m'mitundu yosiyanasiyana, yotembenukira pang'ono, yolunjika, ndi yodutsa mopingasa.
Ma actuator ozungulira nthawi zambiri: imagwiritsidwa ntchito pa ma valve a chipata, ma valve oimitsa, ndi ma valve ena omwe amafunika kuzungulira kangapo kwa chogwirira kuti atsegule ndi kutseka, kapena kuyendetsa ma valve a gulugufe, ma valve a mpira, ma valve a pulagi, ndi ma valve ena otembenukira pang'ono kudzera mu ma drive a zida za worm.
Choyezera chozungulira pang'ono: imagwiritsidwa ntchito pa ma valve a gulugufe, ma valve a mpira, ma valve a pulagi, ndi zina zotero, zomwe zimatha kutsegulidwa ndi kutsekedwa pozungulira madigiri 90
Chowongolera cholunjika: imagwiritsidwa ntchito pa ma valve omwe shaft yake yoyendetsera actuator ndi tsinde la valve zili mbali imodzi
Choyeretsera chodutsa mu ngodya: imagwiritsidwa ntchito pa ma valve omwe shaft yake yoyendetsera actuator ndi tsinde la valve ndi lolunjika
Ma Valves a Actuator a Hydraulic
Ma valve a hydraulic actuator ndi chipangizo choyendetsera ma valve chomwe chimagwiritsa ntchito hydraulic transmission ngati mphamvu. Chinthu chake chodziwika bwino ndi thrust yayikulu, koma ndi yayikulu ndipo ndi yoyenera pazochitika zinazake zomwe zimafuna thrust yayikulu.
Ma Vavulovu Olamulira
Ma valve a actuator a pneumatic, ma valve a actuator a hydraulic, ndi ma valve a actuator amagetsi onse ndi ma valve a Control. Ma valve owongolera amathanso kugawidwa m'magulu awiri.Ma valve a Shutdonw (SDV)ndi Ma Valves Olamulira.
