Bidirectional hard seal butterfly valvendi chitsulo mpaka chitsulo chosindikizidwa.Itha kukhalanso mphete yosindikizira yachitsulo kuchitsulo chosindikizidwa kapena chitsulo chosapanga dzimbiri chosindikizira mphete kupita kuchitsulo chosindikizidwa.Kuphatikiza pamagetsi oyendetsa magetsi, valavu yagulugufe yolimba yanjira ziwiri imathanso kuyendetsedwa pamanja, pneumatically, etc.
Diski wanjira ziwiri zachitsulo chosindikizira gulugufe vavuimayikidwa m'mimba mwake ya payipi.Mu cylindrical channel ya gulugufe valavu thupi, chimbale chimayenda mozungulira axis, ndi kasinthasintha ngodya ndi pakati 0 ° ndi 90 °.Vavu imatsegulidwa kwathunthu pamene chimbale chimazungulira mpaka 90 °.
Wodziwika ndi mawonekedwe apangidwe: amagawidwa kukhala valavu yagulugufe yosindikiza chapakati, valavu yagulugufe yosindikizira imodzi, valavu yagulugufe yosindikiza kawiri,atatu eccentric kusindikiza gulugufe valavu.
Zodziwika ndi kusindikiza zakuthupi: zitha kugawidwa munjira ziwiri zolimba kusindikiza mavavu agulugufe, zomwe nkhope yosindikiza imapangidwa ndi zinthu zofewa zopanda zitsulo kapena zitsulo zolimba kuzinthu zopanda zitsulo zofewa;komanso anawagawa zitsulo zolimba kusindikiza mavavu agulugufe, amene kusindikiza nkhope wapangidwa zitsulo zolimba zipangizo zitsulo zolimba.
Kusungirako, Kuyika ndi Kugwiritsa Ntchito
1. Mapeto onse a valve adzatsekedwa ndikusungidwa m'chipinda chowuma ndi mpweya wabwino.Iyenera kufufuzidwa pafupipafupi kuti isungidwe kwa nthawi yayitali.
2.Valavu iyenera kutsukidwa musanayike kuti ichotse zolakwika zomwe zimachitika panthawi yoyendetsa.
3. Pakuyika, zizindikiro pa valve ziyenera kufufuzidwa.Ndipo chidwi chapadera chiyenera kuperekedwa kuti kayendetsedwe ka kayendedwe ka sing'anga kamagwirizana ndi zomwe zalembedwa pa valve.
4. Kwa ma valve a butterfly omwe ali ndi magetsi oyendetsa magetsi, ziyenera kuzindikirika kuti magetsi okhudzana ndi magetsi ayenera kukhala ofanana ndi omwe ali mu bukhu la chipangizo chamagetsi.
Zolakwa Zomwe Zingatheke, Zomwe Zimayambitsa ndi Njira Zothetsera
1. Kutayikira pa filler
Ngati mtedza wa mbale yosindikizirayo sulimbitsidwa kapena kutsekedwa mosagwirizana, mtedzawo ukhoza kumangika bwino.Ngati kutayikira kukupitirira, kuchuluka kwa kulongedza kungakhale kosakwanira.Panthawi imeneyi, kulongedza katunduyo kungathe kunyamulidwa kachiwiri ndiyeno kumangitsa mtedza.
2. Kutayikira pa gawo losindikiza la ma valve ndi mbale ya disc
1) Tsukani dothi lomwe lili pakati pa malo osindikizira.
2) Ngati malo osindikizira awonongeka, pukutani kapena makina ndikuperanso thupi la valve pambuyo pokonza kuwotcherera.
3) Ngati malo a eccentric ndi osayenera, sinthani malo osakanikirana kuti akhale oyenera panthawi yoika.
