Ma valve oyendetsedwa ndi pneumaticndi zinthu zofunika kwambiri m'mafakitale osiyanasiyana, zomwe zimathandiza kuti madzi ndi mpweya ziziyenda bwino. Ma valve amenewa amagwiritsa ntchitozoyendetsera mpweyakutsegula ndi kutseka makinawo okha, zomwe zimathandiza kuti pakhale njira yolondola yoyendetsera kayendedwe ka madzi ndi kuthamanga kwa madzi. M'nkhaniyi, tifufuza mitundu yosiyanasiyana ya ma valve oyendetsedwa ndi mpweya, kuphatikizapo ma valve oyendetsedwa ndi mpweya, ma valve a gulugufe, ma valve a chipata, ma valve a globe, ndi ma valve a SDV, poganizira kwambiri mawonekedwe awo apadera komanso momwe amagwiritsidwira ntchito.
Kodi valavu yoyendetsedwa ndi pneumatic ndi chiyani?
Valavu yoyendetsera mpweya ndi chipangizo chomwe chimagwiritsa ntchito mpweya wopanikizika kuti chigwiritse ntchito makina a valavu. Choyendetsera mpweya chimasintha mphamvu yomwe ili mu mpweya wopanikizika kukhala kayendedwe ka makina, kutsegula kapena kutseka valavu. Mtundu uwu wa makina odziyimira pawokha ndi wofunikira kwambiri m'mafakitale komwe kugwira ntchito ndi manja sikungatheke kapena sikutetezeka, monga kukonza mankhwala, mafuta ndi gasi, kukonza madzi, ndi kupanga.
Ubwino waukulu wa ma valve oyendetsedwa ndi mpweya ndi liwiro lawo komanso kudalirika kwawo. Angagwiritsidwe ntchito mwachangu, zomwe zimapangitsa kuti akhale abwino kwambiri pa ntchito zomwe zimafuna nthawi yoyankha mwachangu. Kuphatikiza apo, makina oyendetsedwa ndi mpweya nthawi zambiri amakhala osavuta komanso otsika mtengo kuposa makina amagetsi kapena a hydraulic, zomwe zimapangitsa kuti azidziwika m'malo ambiri amafakitale.
Mitundu ya Oyambitsa Pneumatic
1. Valavu ya mpira wa pneumatic
Ma Valves a Mpira wa Pneumatic ActuatorMa valve awa apangidwa ndi diski yozungulira (mpira) kuti azitha kuyendetsa madzi kudzera mu valavu. Mpira ukazungulira madigiri 90, umalola kapena kuletsa madzi kuyenda. Ma valve awa amadziwika kuti ndi abwino kwambiri potseka komanso kuchepetsa kupanikizika, zomwe zimapangitsa kuti akhale oyenera kugwiritsidwa ntchito ndi madzi othamanga kwambiri.
Ma valve a mpira amagwiritsidwa ntchito kwambiri m'mafakitale amafuta ndi gasi, madzi ndi mankhwala. Ma valve a mpira amagwira ntchito mwachangu, amakhala olimba ndipo ndi chisankho choyamba pakugwiritsa ntchito mphamvu yoyatsa/kuzima.
2. Valavu ya gulugufe ya pneumatic
Ma valve a gulugufe amagwiritsa ntchito diski yozungulira kuti azitha kuyendetsa bwino kayendedwe ka madzi. Disikiyo imayikidwa pa shaft ndipo imatha kuzunguliridwa kuti itsegule kapena kutseka valavuyo.Ma valve a gulugufe a actuator a pneumaticNdi othandiza kwambiri makamaka pa ntchito zomwe zimafuna kuthamanga kwa madzi ambiri komanso kutsika kwa mphamvu ya mpweya.
Ma valve awa ndi opepuka komanso ang'onoang'ono, zomwe zimapangitsa kuti akhale abwino kwambiri poyika malo omwe ali ochepa. Chifukwa cha kugwira ntchito bwino komanso kusamalitsa kosavuta, amagwiritsidwa ntchito kwambiri m'makina a HVAC, m'malo oyeretsera madzi, komanso m'mafakitale opangira chakudya.
3. Valavu ya chipata cha pneumatic
Ma valve a chipata apangidwa kuti apereke njira yowongoka yoyendera madzi, kuchepetsa kutayika kwa mphamvu. Amagwira ntchito pokweza chipata kutali ndi njira yoyendera madzi, zomwe zimathandiza kuti madzi aziyenda bwino akatsegulidwa.Ma valve a chipata oyendetsedwa ndi pneumaticallynthawi zambiri amagwiritsidwa ntchito pa ntchito zomwe zimafuna kutsekedwa bwino, monga makina operekera madzi ndi mapaipi amafuta.
Ngakhale ma valve a chipata si abwino kwambiri pogwiritsira ntchito mphamvu yamagetsi, amatha bwino kwambiri poyendetsa magetsi ndi kuwayatsa. Kapangidwe kake kolimba komanso kuthekera kopirira kupsinjika kwakukulu kumawapangitsa kukhala oyenera kugwiritsidwa ntchito m'mafakitale osiyanasiyana.
4. Valavu ya padziko lonse ya actuator ya pneumatic
Valavu ya globe ili ndi thupi lozungulira ndipo imagwiritsidwa ntchito pokoka. Disikiyi imayenda molunjika ku mbali ya madzi, zomwe zimathandiza kuti kayendedwe ka madzi kayende bwino. Valavu ya globe yoyendetsedwa ndi pneumatic nthawi zambiri imagwiritsidwa ntchito m'malo omwe malamulo oyendetsera kayendedwe ka madzi ndi ofunikira kwambiri, monga machitidwe a nthunzi ndi kukonza mankhwala.
Ma valve amenewa amapereka mphamvu yabwino kwambiri yoyendetsera kayendedwe ka madzi ndipo ndi oyenera kugwiritsidwa ntchito pogwiritsa ntchito mphamvu yamagetsi. Komabe, amatha kukhala ndi mphamvu yamagetsi yotsika kwambiri kuposa mitundu ina ya ma valve, zomwe zimapangitsa kuti asamagwiritsidwe ntchito mosayenera pogwiritsa ntchito mphamvu yamagetsi yomwe siifuna mphamvu zambiri.
5. Valavu ya SDV (valavu yotseka)
Ma valve otseka (SDVs) ndi zida zofunika kwambiri zotetezera zomwe zimagwiritsidwa ntchito m'mafakitale osiyanasiyana kuti apewe kuyenda kwa zinthu zoopsa panthawi yadzidzidzi kapena kukonza. Ma valve a SDV oyendetsedwa ndi mpweya amapangidwa kuti atseke mwachangu komanso mosamala, kuonetsetsa kuti kuyenda kwa madzi kumayimitsidwa nthawi yomweyo pakafunika kutero.
Ma valve amenewa nthawi zambiri amagwiritsidwa ntchito m'malo opangira mafuta ndi gasi, m'mafakitale opanga mankhwala, ndi m'malo ena omwe ali pachiwopsezo chachikulu. Kudalirika kwawo komanso nthawi yogwira ntchito mwachangu zimapangitsa kuti akhale ofunikira kuti asunge chitetezo komanso kutsatira malamulo amakampani.
Kugwiritsa Ntchito Valve ya Pneumatic Actuator
Ma valve oyendetsedwa ndi mpweya amagwiritsidwa ntchito m'mafakitale osiyanasiyana chifukwa cha kusinthasintha kwawo komanso kugwira ntchito bwino. Ntchito zina zomwe zimagwiritsidwa ntchito nthawi zambiri ndi izi:
- Kukonza MankhwalaMa valve oyendetsedwa ndi mpweya amagwiritsidwa ntchito kuwongolera kayendedwe ka mankhwala mu ma reactor, ma mixer ndi matanki, kuonetsetsa kuti mlingo ndi kusakaniza molondola.
- Mafuta ndi Gasi: Ma valve amenewa amagwira ntchito yofunika kwambiri powongolera kuyenda kwa mafuta osakonzedwa, gasi wachilengedwe, ndi zinthu zoyengedwa m'mapaipi ndi malo opangira zinthu.
- Kuchiza Madzi: Malo oyeretsera madzi amagwiritsa ntchito ma valve oyendetsedwa ndi mpweya kuti azitha kuyendetsa bwino kayendedwe ka madzi ndi mankhwala omwe amagwiritsidwa ntchito poyeretsa.
- Machitidwe a HVAC: Mu makina otenthetsera, opumira mpweya, ndi oziziritsa mpweya, ma valve awa amathandiza kulamulira kayendedwe ka mpweya ndi kutentha, motero kumawonjezera kugwiritsa ntchito mphamvu moyenera komanso chitonthozo.
- Chakudya ndi ChakumwaMa valve oyendetsedwa ndi mpweya amagwiritsidwa ntchito pokonza chakudya kuti atsimikizire kuti zosakaniza ndi zinthu zimagwiritsidwa ntchito bwino komanso mosamala.
Pomaliza
Ma valve oyendetsedwa ndi pneumaticndi gawo lofunikira kwambiri pa ntchito zamakono zamafakitale, zomwe zimapereka ulamuliro wodalirika komanso wothandiza wa kuyenda kwa madzi ndi mpweya. Ma valve oyendetsedwa ndi pneumatic amapezeka m'mitundu yosiyanasiyana, kuphatikizapo ma valve a mpira, ma valve a gulugufe, ma valve a chipata, ma valve a globe, ndi ma valve a SDV, zomwe zimathandiza mafakitale kusankha njira yoyenera kwambiri pakugwiritsa ntchito kwawo. Kumvetsetsa mawonekedwe apadera ndi ubwino wa mtundu uliwonse wa valavu yoyendetsedwa ndi pneumatic ndikofunikira kwambiri pakukonza magwiridwe antchito ndikuwonetsetsa kuti ntchito zamafakitale zili bwino. Pamene ukadaulo ukupitilira patsogolo, ntchito ya ma valve oyendetsedwa ndi pneumatic pakukweza magwiridwe antchito ndi kudalirika kwa njira idzakhala yofunika kwambiri.
