Mavavu agulugufe ndi ma valve otembenukira kotala omwe amagwiritsidwa ntchito kuwongolera kuyenda.The metal disc muvalavuthupi ndi perpendicular kwa madzimadzi mu chatsekedwa udindo ndi zimayenda kotala kutembenukira kuti kufanana ndi madzimadzi mu malo otseguka kwathunthu.Kasinthasintha wapakatikati amalola kusintha kwa madzi otaya.Amagwiritsidwa ntchito kwambiri paulimi ndi madzi kapena kugwiritsa ntchito madzi otayira ndipo ndi imodzi mwa mitundu yodziwika bwino komanso yodziwika bwino ya ma valve.

Ubwino wavalavu ya butterfly
Ma valve a butterfly ndi ofanana ndi ma valve a mpira, koma ali ndi ubwino wambiri.Ndi ang'onoang'ono ndipo, akamayendetsedwa ndi pneumatic, amatha kutsegula ndi kutseka mwachangu kwambiri.Diskiyo ndi yopepuka kuposa mpira, ndipo valavu imafuna chithandizo chocheperako kuposa valavu ya mpira yofananira.Ma valve a butterfly ndi olondola kwambiri, zomwe zimawapatsa mwayi pamafakitale.Iwo ndi odalirika kwambiri ndipo amafuna chisamaliro chochepa.

Zoyipa za valavu ya butterfly
Choyipa chimodzi cha ma valve a butterfly ndikuti mbali ina ya diski imakhalapo nthawi zonse, ngakhale itatsegulidwa kwathunthu.Chifukwa chake, kugwiritsa ntchito valavu yagulugufe nthawi zonse kumapangitsa kusinthana kwa valve pa valve, mosasamala kanthu za malo.

Magetsi, Pneumatic kapena Mavavu Agulugufe Ogwiritsidwa Ntchito Pamanja

Mavavu a butterflyikhoza kukhazikitsidwa kuti igwiritsidwe ntchito pamanja, magetsi kapena pneumatic.Ma valve a pneumatic amagwira ntchito mwachangu kwambiri.Mavavu amagetsi amafunika kutumiza chizindikiro ku gearbox kuti atsegule kapena kutseka, pomwe ma valve a pneumatic amatha kukhala amodzi kapena awiri.Ma valve opangidwa ndi amodzi nthawi zambiri amakhazikitsidwa kuti afune chizindikiro kuti atsegule ndi failsafe, zomwe zikutanthauza kuti mphamvu ikatha, valavu imabwerera kumalo otsekedwa kwathunthu.Mavavu apawiri opangidwa ndi pneumatic samadzaza masika ndipo amafunikira chizindikiro kuti atsegule ndi kutseka.

Mavavu agulugufe opangidwa ndi pneumatic ndi odalirika komanso olimba.Kuchepetsa kuvala kumapangitsa kuti ma valve ayende bwino, motero amachepetsa ndalama zogwirira ntchito zomwe zingatayike mu maola ogwira ntchito posamalira valavu.
