Mavavu opangidwa ndi pneumaticndi zigawo zofunika mu njira zosiyanasiyana za mafakitale, kulamulira bwino kutuluka kwa madzi ndi mpweya. Ma valve awa amagwiritsa ntchitopneumatic actuatorskuti mutsegule ndi kutseka makinawo, kulola kuwongolera bwino kwakuyenda ndi kuthamanga. M'nkhaniyi, tiwona mitundu yosiyanasiyana ya ma valve opangidwa ndi pneumatically-actuated, kuphatikizapo ma valve opangidwa ndi pneumatically-actuated, ma valve a butterfly, ma valve a zipata, ma valve a globe, ndi ma valve a SDV, poyang'ana mawonekedwe awo apadera ndi ntchito.
Kodi valavu ya pneumatic actuated ndi chiyani
Valavu ya pneumatic actuator ndi chipangizo chomwe chimagwiritsa ntchito mpweya woponderezedwa kuti ugwiritse ntchito makina a valve. The actuator amasintha mphamvu mu mpweya woponderezedwa kukhala makina kuyenda, kutsegula kapena kutseka valavu. Makina amtundu uwu ndi ofunika kwambiri m'mafakitale omwe ntchito zamanja sizingachitike kapena zosatetezeka, monga kukonza mankhwala, mafuta ndi gasi, kukonza madzi, ndi kupanga.
Ubwino waukulu wa ma valve pneumatically actuated ndi liwiro lawo komanso kudalirika. Atha kugwiritsidwa ntchito mwachangu, kuwapangitsa kukhala abwino kwa mapulogalamu omwe amafunikira nthawi yoyankha mwachangu. Kuphatikiza apo, makina a pneumatic nthawi zambiri amakhala osavuta komanso otsika mtengo kuposa magetsi kapena ma hydraulic, kuwapangitsa kukhala otchuka m'mafakitale ambiri.
Mitundu ya Pneumatic Actuators
1. Vavu ya mpira wa pneumatic
Pneumatic Actuator Ball Valvesadapangidwa ndi diski yozungulira (mpira) kuti azitha kuyendetsa madzi kudzera mu valve. Mpirawo ukazungulira madigiri 90, umalola kapena kutsekereza kutuluka kwamadzi. Ma valve awa amadziwika chifukwa cha kusindikiza kwawo kwabwino kwambiri komanso kutsika pang'ono kwa kuthamanga, kuwapangitsa kukhala oyenera kugwiritsa ntchito madzi othamanga kwambiri.
Ma valve a mpira amagwiritsidwa ntchito kwambiri m'mafakitale amafuta ndi gasi, m'mafakitale operekera madzi ndi kukonza mankhwala. Mavavu a mpira ndi othamanga kugwira ntchito, olimba ndipo ndi chisankho choyamba pa / off control applications.
2. Vavu ya butterfly ya pneumatic
Ma valve a butterfly amagwiritsa ntchito diski yozungulira kuti aziwongolera kuyenda. Diskiyo imayikidwa pa shaft ndipo imatha kuzunguliridwa kuti itsegule kapena kutseka valavu.Ma valve agulugufe a pneumatic actuatorndizopindulitsa kwambiri pazogwiritsa ntchito zomwe zimafuna kuthamanga kwambiri komanso kutsika kwapansi.
Mavavuwa ndi opepuka komanso ophatikizika, kuwapangitsa kukhala abwino kwa makhazikitsidwe pomwe malo ali ochepa. Chifukwa chakuchita bwino kwambiri komanso kukonza kosavuta, amagwiritsidwa ntchito kwambiri m'makina a HVAC, malo opangira madzi, komanso mafakitale opanga zakudya.
3. Vavu ya chipata cha pneumatic
Ma valve a zipata amapangidwa kuti apereke njira yowongoka yoyenda, kuchepetsa kutaya kwamphamvu. Amagwira ntchito pokweza chipata kutali ndi njira yodutsa, kulola kutuluka kwathunthu pamene kutsegulidwa.Ma valve a zipata zoyendetsedwa ndi pneumaticNthawi zambiri amagwiritsidwa ntchito pamapulogalamu omwe amafunikira chisindikizo cholimba, monga njira zoperekera madzi ndi mapaipi amafuta.
Ngakhale ma valve a zipata si abwino kuti agwiritse ntchito, amapambana pa / off control scenarios. Zomangamanga zawo zolimba komanso kuthekera kolimbana ndi zovuta zazikulu zimawapangitsa kukhala oyenera ntchito zosiyanasiyana zamakampani.
4. Pneumatic actuator globe valve
Valve yapadziko lonse lapansi imakhala ndi thupi lozungulira ndipo imagwiritsidwa ntchito popumira. Chimbale chimayenda perpendicular kwa kayendedwe ka madzimadzi, kulola kuwongolera kulondola kwakuyenda. Ma valve opangidwa ndi pneumatic actuated globe nthawi zambiri amagwiritsidwa ntchito m'malo omwe kuwongolera koyenda ndikofunikira, monga makina a nthunzi ndi kukonza mankhwala.
Ma valve awa amapereka kayendetsedwe kabwino ka kayendedwe kake ndipo ndi oyenera kugwiritsira ntchito kuthamanga kwambiri. Komabe, amatha kutsika kwambiri kuposa mitundu ina ya mavavu, kuwapangitsa kukhala osayenerera kugwiritsa ntchito zomwe zimafunikira kukana pang'ono.
5. Vavu ya SDV (valavu yotseka)
Ma valve a Shutoff (SDVs) ndi zida zofunika zotetezera zomwe zimagwiritsidwa ntchito m'mafakitale osiyanasiyana pofuna kupewa kutuluka kwa zinthu zoopsa panthawi yadzidzidzi kapena kukonza. Ma valve a SDV opangidwa ndi pneumatically actuated amapangidwa kuti atseke mwachangu komanso mosatekeseka, kuwonetsetsa kuti kutuluka kwayimitsidwa nthawi yomweyo pakufunika.
Ma valve awa nthawi zambiri amagwiritsidwa ntchito m'malo opangira mafuta ndi gasi, malo opangira mankhwala, ndi malo ena omwe ali pachiwopsezo chachikulu. Kudalirika kwawo komanso nthawi yoyankha mwachangu zimawapangitsa kukhala ofunikira kuti akhalebe otetezeka komanso kutsatira malamulo amakampani.
Kugwiritsa ntchito Pneumatic Actuator Valve
Ma valve opangidwa ndi pneumatic amagwiritsidwa ntchito m'mafakitale osiyanasiyana chifukwa cha kusinthasintha kwawo komanso kuchita bwino. Ntchito zina zodziwika bwino ndi izi:
- Chemical Processing: Ma valve opangidwa ndi pneumatic amagwiritsidwa ntchito kuwongolera kutuluka kwa mankhwala mu reactors, mixers ndi akasinja, kuonetsetsa dosing yolondola ndi kusakaniza.
- Mafuta & Gasi: Mavavuwa amagwira ntchito yofunika kwambiri pakuwongolera kayendedwe ka mafuta osapsa, gasi, ndi zinthu zoyengedwa bwino pamapaipi ndi malo opangira zinthu.
- Chithandizo cha Madzi: Malo opangira madzi amagwiritsa ntchito ma valve opangidwa ndi pneumatic kuti azitha kuyendetsa madzi ndi mankhwala omwe amagwiritsidwa ntchito poyeretsa.
- HVAC Systems: Potenthetsera, mpweya wabwino, ndi makina owongolera mpweya, mavavuwa amathandiza kuwongolera kayendedwe ka mpweya ndi kutentha, potero kumapangitsa kuti mphamvu ziziyenda bwino komanso kutonthoza.
- Chakudya ndi Chakumwa: Mavavu opangidwa ndi pneumatic amagwiritsidwa ntchito pokonza chakudya kuonetsetsa kuti zosakaniza ndi zinthu zikuyenda bwino.
Pomaliza
Ma valve opangidwa ndi pneumaticallyndi gawo lofunikira la njira zamakono zamafakitale, zomwe zimapereka kuwongolera kodalirika komanso koyenera kwamadzi ndi gasi. Ma valve opangidwa ndi pneumatically amapezeka mumitundu yosiyanasiyana, kuphatikizapo ma valve a mpira, ma valve a butterfly, ma valve a pakhomo, ma valve a globe, ndi ma valve a SDV, zomwe zimalola mafakitale kusankha njira yoyenera kwambiri pa ntchito yawo yeniyeni. Kumvetsetsa mawonekedwe apadera ndi mapindu amtundu uliwonse wa valavu ya pneumatically-actuated ndikofunikira kuti kukhathamiritsa magwiridwe antchito ndikuwonetsetsa kuti ntchito zamakampani zikuyenda bwino. Pamene teknoloji ikupitirirabe patsogolo, ntchito ya mavavu opangidwa ndi pneumatically-actuated kuti apititse patsogolo kayendetsedwe kabwino kachitidwe ndi kudalirika kudzakhala kofunika kwambiri.
