Chifukwa kayendedwe ka gulugufe valavu mbale ndi kupukuta, kotero ambiri avalavu ya butterflyangagwiritsidwe ntchito ndi inaimitsidwa olimba particles wa sing'anga, malinga ndi mphamvu ya chisindikizo Angagwiritsidwenso ntchito ufa ndi granular media.

Kutalika kwa valavu ya butterfly ndi kutalika kwake ndi kochepa, kotseguka ndi kutseka mofulumira, pamene kutseguka kwathunthu, ndi kukana madzimadzi pang'ono, pamene kutsegulidwa kwa pafupifupi 15 mpaka 70, komanso kulamulira tcheru kutuluka, mfundo ya butterfly Valve ndiyoyenera kwambiri kupanga mavavu akuluakulu awiri.

Valavu ya butterfly ikulimbikitsidwa pansi pazikhalidwe 5 zotsatirazi:

1. Pemphani kugwedezeka, kuwongolera ndi kuwongolera kuyenda.
2. Matope Apakati komanso olimba okhala ndi tinthu tating'ono.
3. Kutalika kwa mawonekedwe a valve ndi nthawi yochepa.
4. Amafuna nthawi yotsegula ndi kutseka mwachangu.
5. Mikhalidwe yokhala ndi kusiyana kwapang'onopang'ono.

Mukusintha kwapawiri, khosi la khosi, phokoso lochepa, cavitation ndi chodabwitsa cha gasification, kutayikira pang'ono kumlengalenga, media abrasive, mutha kusankha valavu yagulugufe.

Mukamagwiritsa ntchito valavu yagulugufe pansi pamikhalidwe yapadera yogwirira ntchito, monga kuwongolera kapena kusindikiza mwamphamvu, kapena kung'ambika kwambiri, kutentha pang'ono (kuzizira kwambiri) ndi zinthu zina zogwirira ntchito, valavu yapadera yagulugufe yokhala ndi lamba wosindikiza wachitsulo wapadera imafunika. kugwiritsa ntchito valavu yapadera yamagulugufe atatu kapena awiri eccentric.

Valovu ya gulugufe imayendetsedwa ndi giya ya nyongolotsi ndi nyongolotsi yomwe imayendetsa shaft ndi mbale yagulugufe kuti itsegule ndi kutseka ndikuwongolera kuyenda.Mozungulira nyongolotsi zida nyongolotsi gearing gudumu m'manja, kuti chimbale kutsegula ndi kutseka ndi kusintha otaya, dzanja gudumu molunjika malangizo kasinthasintha kwa valavu kutsekedwa.

Gwiritsani Ntchito Chipangizo

Malinga ndi magetsi kulamulira amafuna wa chingwe pachimake waya kwa terminal lolingana, ndi losindikizidwa chingwe polowera, pa nthawi yomweyo chingwe anakonza kuteteza kunja kukokera kuwonongeka chingwe mawaya.Vavu ikakhala pamalo "yonse", tembenuzirani CAM pansipa molunjika kapena kamera yotseguka pamwamba pawotchiyo.Pamene valavu agulugufe ndi clamped, tcherani khutu ngati kulumikiza mphamvu ndi ngakhale ndi odalirika.Vavu yagulugufe ikayikidwa, mbale ya valve iyenera kukhala pamalo otseguka poyesa mphamvu ya payipi.Gulugufe valavu unsembe ayenera kuyendera nthawi zonse, kuyendera zinthu zazikulu motere: mpando wagulugufe valavu ndi o-mphete ngati kuwonongeka.Kusindikiza ntchito ya valve plate yosindikiza pamwamba.Vavu yagulugufe ikakonzedwa ndikusonkhanitsidwa, sipadzakhala kutsekeka panthawi yotsegulira ndi kutseka.Msonkhano wokonza ma valve a butterfly uyenera kupitiliza kuyesa ntchito yosindikiza malinga ndi pempho.
