Vavu ya Mpira Yoyendetsedwa ndi Moto

Chidule cha Zamalonda

Valavu ya mpira yoyendetsedwa ndi injini ndi chipangizo chowongolera kuyenda kwa madzi chomwe chimaphatikiza actuator yamagetsi ndi valavu ya mpira wamba. Mwa kuzungulira mpirawo 90° mozungulira mzere wolunjika ku njira yoyendera, valavuyo imatsegula, kutseka, kapena kutseka kolondola. Yoyendetsedwa ndi AC220V, AC380V, kapena DC24V, actuator imayankha ma signal a 4‑20mA current kapena voltage kuchokera ku dongosolo lowongolera, kupereka kuzungulira kwa angular kwa 0‑90° kuti ilamulire kapena kutseka bwino cholumikizira chomwe chili mupaipi.

Chipangizochi chili ndi kapangidwe ka makina olumikizirana - choyendetseracho chili ndi makina olumikizirana omwe ali mkati mwake, zomwe zimapangitsa kuti pasakhale kufunikira kwa chowonjezera cha servo chakunja. Bowo la thupi la valavu limagwirizana kwathunthu ndi chitoliro cholumikizira, zomwe zimathandiza kuti cholumikiziracho chidutse popanda kukana kulikonse.

Zinthu Zofunika Kwambiri

• Kukana Madzi Ochepa– Pakati pa mitundu yonse ya ma valavu, valavu ya mpira imapereka kukana kotsika kwambiri kwa kayendedwe ka madzi. Ngakhale ma model a reduced bore amakhala ndi kutsika kwa mphamvu kwa mpweya, pomwe mapangidwe a full port amatsimikizira kutayika pang'ono kwa mutu.

•Kugwira Ntchito Kwambiri Yosindikiza– Mpandowu umagwiritsa ntchito zinthu zolimba monga PTFE, zomwe zimapangitsa kuti ukhale wolimba komanso womasuka pamene mphamvu ya chingwe ikukwera. Kutseka mwamphamvu kwa thovu (kusiya kutayikira) n'kotheka.

•Ntchito Yosalala & Yokhazikika- Ma bearing othrash amachepetsa kukangana kwa tsinde, zomwe zimapangitsa kuti ntchito ikhale yosavuta komanso yayitali. Tsinde limazungulira popanda kuyenda mozungulira, zomwe zimasunga kulimba kwa kulongedza ndikuwonjezera kutseka pamene kupanikizika kukukwera.

•Moyo Wowonjezera wa Utumiki– PTFE ndi zipangizo zina zofanana zili ndi mphamvu zabwino zodzipaka mafuta, kuchepetsa kukangana motsutsana ndi mpira ndikuwonjezera nthawi ya valavu.

•Zinthu Zotetezeka Zomangidwa– Kapangidwe ka tsinde losaphulika (lokhala ndi phewa losunga) kamaletsa kutuluka kwa tsinde. Kasupe woteteza kuphulika amatulutsa bwino magetsi osasunthika omwe amapangidwa panthawi yosinthana. Mitundu yoteteza kuphulika (ExdII BT4) imapezeka m'malo oopsa.

•Yochepa & Yosavuta Kuyika– Choyatsira chimayikidwa mwachindunji pa valavu, zomwe zimapangitsa kuti pakhale malo osungiramo malo komanso opepuka okhala ndi mawaya osavuta - abwino kwambiri pamapaipi olimba.

Miyezo Yopangira Zinthu

Thevalavu ya mpira yamagetsi yamagetsiYapangidwa ndikupangidwa motsatira miyezo yodziwika padziko lonse lapansi, kuphatikiza GB/T12237, API 608, API 6D, DIN 3357, ndi BS 5351. Miyeso ya flange ikhoza kuperekedwa ku GB, ANSI, JIS, DIN, kapena miyezo ina kuti ikwaniritse zofunikira za polojekiti padziko lonse lapansi.

Mitundu Yowongolera

Pali njira ziwiri zazikulu zowongolera zomwe zimaperekedwa kuti zigwirizane ndi zosowa zosiyanasiyana zodziyimira pawokha:

•Mtundu wa YATSA/ZIMISA (Sinthani)– Valavu imayendetsedwa motseguka kapena kutsekedwa kwathunthu posintha magetsi. Ndi yabwino kwambiri poyimitsa kapena kuyimitsa magetsi m'malo awiri.

•Mtundu Wosintha (Wowongolera)- Imalandira chizindikiro cha analogue cha 4‑20mA (kapena 0‑10mA, 1‑5VDC) kuti chiyike mpirawo pakati pa 0° ndi 90°, zomwe zimathandiza kuti pakhale kuwongolera kolondola kwa kayendedwe ka madzi, kuthamanga kwa mpweya, kapena kutentha.

Zofalitsa Zogwiritsidwa Ntchito

Valavu yamagetsi yamagetsi ndi yoyenera madzi osiyanasiyana, kuphatikizapo madzi, zosungunulira, ma asidi, gasi wachilengedwe, mafuta, nthunzi, ndi zinthu zamafuta. Chifukwa cha kapangidwe kake kotseka bwino komanso kosatsekeka, imagwira ntchito bwino kwambiri ndi madzi okhuthala, matope okhala ndi tinthu tating'onoting'ono, fibrous media, ndi zamkati. Imathanso kuthana ndi zovuta monga mpweya, hydrogen peroxide, methane, ndi ethylene.

Minda Yofunsira

Monga valavu yowongolera yokha, chinthu ichi chimagwiritsidwa ntchito kwambiri mu:

•Mafuta ndi Gasi- Kuwongolera kayendedwe ka madzi ndi kutseka kwadzidzidzi m'mapaipi.

•Kupanga Mphamvu- Malo otenthetsera kwambiri komanso opanikizika kwambiri m'madzi ophikira ndi makina a nthunzi m'maboiler.

•Zachitsulo ndi Chitsulo- Kulamulira kayendedwe ka mpweya wotentha ndi zakumwa m'mafakitale akuluakulu.

•Kuchiza Madzi ndi Madzi Otayira- Kuyenda kwa matope, matope, ndi madzi okhuthala.

•Zamkati ndi Pepala- Zinthu zokhala ndi ulusi ndi zokutira.

•HVAC & Firiji- Kuyatsa/kuzima ndi kusintha kayendedwe ka madzi otentha/ozizira.

•Chakudya ndi Mankhwala- Mizere yogwirira ntchito zaukhondo (yokhala ndi zipangizo zoyenera komanso zomalizidwa).

Zindikirani:Zomwe zili pamwambapa zikuwonetsa momwe zinthu zilili. Zosankha zomwe zasinthidwa zikupezeka kutengera momwe zinthu zilili - chonde funsani gulu lathu laukadaulo kuti likuthandizeni kusankha.
