Valavu ya butterfly yapakati ili ndi dongosolo losavuta komanso losavuta kupanga, koma chifukwa cha kapangidwe kake ndi zofooka zakuthupi, zogwiritsira ntchito ndizochepa.Kuti akwaniritse zofunikira za momwe angagwiritsire ntchito, kukonzanso kosalekeza kwachitika pa maziko awa, ndiyeno mavavu agulugufe amodzi, ma valve a butterfly eccentric, ndi ma valve a butterfly eccentric atatu awonekera.Chochititsa chidwi kwambiri chachitatu ichi ndi chakuti chimasintha mawonekedwe osindikizira.Sichisindikizo chokhazikika, koma chisindikizo cha torsion, ndiko kuti, sichidalira kusinthika kwa mpando wa valve, koma kumadalira kwathunthu kukhudzana ndi kukhudzana kwapampando wa mpando wa valve.Chifukwa chake, kusindikiza kumathetsa vuto la zero kutayikira kwa mpando wa valavu yachitsulo mumphindi imodzi yakugwa, ndipo chifukwa kupanikizika kwapamtunda kumayenderana ndi kuthamanga kwapakatikati, kuthamanga kwambiri komanso kukana kutentha kumathetsedwanso mosavuta.

Ubwino wa katatu eccentric design

1. Chisindikizo chapadera cha conical chimatsimikizira kuti diski sichikhudza malo osindikizira mpaka valve itatsekedwa-izi zimatsogolera ku chisindikizo chobwerezabwereza ndikuwonjezera kwambiri moyo wautumiki wa valve.

2. Maonekedwe a mbale ya valve ya katatu eccentric butterfly valve ndi elliptical cone, ndipo pamwamba pake ndi yowotcherera ndi alloy olimba, omwe ali ndi kukana kwambiri kuvala.Mpando wachitsulo wosapanga dzimbiri woyandama wa U uli ndi ntchito yosinthira zokha pakati.Vavu ikatsegulidwa, valavu ya elliptical cone yosindikiza pamwamba imasiyanitsidwa ndi mpando wa valve zotanuka wooneka ngati U, kenako imazungulira;ikatsekedwa, chimbale cha valve chimazungulira, ndipo chimbale cha valve chimasintha pakati pa mpando wa valve zotanuka pansi pa zochitika za shaft eccentric.Mpandowo umagwiritsa ntchito kukakamiza kusokoneza mpando wa valve mpaka mpando wa valve ndi elliptical conical kusindikiza pamwamba pa diski ya valve ikugwirizana kwambiri.Vavu ikatsegulidwa ndikutsekedwa, chimbale cha butterfly sichimakanda mpando wa valavu, ndipo torque ya tsinde la valavu imaperekedwa mwachindunji kumalo osindikizira kudzera mu mbale ya butterfly, ndipo torque yotsegulira ndi yaying'ono, potero imachotsa chodabwitsa chodumpha. potsegula valavu.

3. Kusindikiza kwachitsulo ndi zitsulo kumatsimikizira kuti mpweya wotsekemera umatsekedwa mwamphamvu kuti zitheke kutulutsa zero.

4. Yoyenera pa media media-chopangidwa ndi zitsulo zonse chimapereka dzimbiri komanso kukana kutentha komwe ma valve ena agulugufe amakhala ndi zisindikizo zotanuka alibe.

5. Mapangidwe a geometric a zigawo zosindikizira angapereke maulendo opanda frictionless mu valve.Izi zimatalikitsa moyo wa valavu ndikulola kuyika kwa ma torque actuators otsika.

6. Palibe phokoso pakati pa zigawo zosindikizira, zomwe sizingayambitse kutsekeka, kuchepetsa ndalama zothandizira komanso kukulitsa moyo wa valve.

7. Mapangidwe a mipando ya valve amatha kulepheretsa valavu kuti isapitirire
