Iyini i-Butterfly Valve: Imiyalelo Eningiliziwe Esebenzayo

Iyini i-Butterfly Valve

A ivalvu yebhabhathaneiyivalvu yokujika ngekota enediski ejikelezayo (ipuleti levemvane) enamathiselwe esiqwini esiphakathi. Lo mklamo omncane wenza kube lula ukulawula ukugeleza okusheshayo noma ukuhlukaniswa kwamapayipi. Njengoba isetshenziswa kabanzi kuzo zonke izimboni, amavalvu evemvane avelele ezinhlelweni ezidinga izixazululo ezingabizi kakhulu nezilula ezinokwehla komfutho ophansi.

Isakhiwo se-Butterfly Valve: Izingxenye Ezi-4 Eziyinhloko

1. Umzimba weValve: Indlu ye-cylindrical (insimbi ehlanganisiwe, insimbi engagqwali, noma insimbi ehlanganisiwe) eneziphetho ezigobile/ezigobile/ezihlanganisiwe.

2. Idiski Yevalvu: Ukugeleza okulawula ipuleti elijikelezayo – kutholakala ngokulungiswa okuqondile, okuphindwe kabili/kathathu.

3. Isiqu: Ixhuma i-actuator kwidiski ukuze idlulisele i-torque.

4. Isihlalo: Indawo yokuvala (irabha ethambile, i-PTFE, noma insimbi) eqinisekisa ukuvalwa okuqinile okuvuzayo.

Asebenza Kanjani Ama-valve E-Butterfly

Amavalvu e-Butterfly ayizingxenye eziyisisekelo ezinhlelweni zokulawula uketshezi zanamuhla, aziswa ngobulula bawo, ukwakheka kwawo okuncane, kanye nokusebenza kwawo okusheshayo. Kodwa isebenza kanjani ngempela le valve eguquguqukayo?

Isimiso Sokusebenza Esiyinhloko: I-Rotating Disc

Inhliziyo yevalvu yebhabhathane iyidiski eyindilinga (noma i-vane) efakwe esiqwini esijikelezayo ngaphakathi kwebhore lepayipi. Ukulawulwa koketshezi kufezwa ngokuphelele ngokunyakaza okubalulekile kwediski:

Idiski ijikeleza ngama-90° phakathi:

-Ivuliwe Ngokugcwele: Idiski iqondanisa ngokuhambisana nokugeleza (ukulahlekelwa okuncane kwengcindezi)

-Kuvaliwe Ngokugcwele: Amabhulokhi ediski ageleza ngokuqondile epayipini

Ukuqaliswa Kokuvula Nokugeleza: Ukujikeleza Kuye Ekuvumeleni Ukugeleza

• Uma ivuliwe (ngesandla ngesondo lesandla, noma ngokuzenzakalelayo nge-actuators kagesi/yomoya), isiqu sizungezisa idiski sisuka endaweni yaso evaliwe (ngokuqondile ekugelezeni) siye endaweni evulekile.

• Njengoba idiski ijikeleza (ngokuvamile kusuka ku-0° kuya ku-90°), iyasuka esihlalweni sevalvu, idale indlela yokuthi uketshezi lugeleze emaphethelweni ayo kanye/noma ludlule endaweni ephakathi uma ikhona.
