Njiisyo yakubeleka akuyakwa akubikka ntambo zya raba

Chivvalavu yabutterfly iikkede a rabaninzila imwi ya vvalavu iibelesya bbwe lyakuzunguluka mbuli chibeela chakujalula akujala mpawo lizungaana achisiko cha vvalavu kujalula, kujala akubamba nzila yamaanzi. Ipuleti lyamubala wavvalavu yabutterfly iikkede a rabalibikkidwe munzila yabwamba bwamupayipi. Munzila iili mbuli bbola lyavvalavu yabutterfly iikkede a rabamubili, bbaaji lyamubala uuli mbuli disiki lilazungaana kuzyunguluka ntalisyo, mpawo nzila yakuzungaana ili akati ka 0° a 90°. Eelyo nolizungaana kusika ku 90°, vvalavu ilajaluka.

Masena aakuyaka akubikka

1. Busena bwakubikkila, bulamfu, anzila yakunjizya akutola kunze kweelede kweendelana aziyandikana, mpawo kujatana kweelede kuba kuyumu akuyuma.

2. Kumisyobo yoonse yamavalvu aabelesyegwa amaanza aabikkidwe aamupayipi wakukwabilila kupya, ntalisyo tayelede kuba ansi pe.

3. Kulanga-langa kweelede kuchitwa kakutanabikkwa vvalavu, mpawo zina lya vvalavu lyeelede kuzuzikizya ziyandikana zyamulawu wanyika yoonse "General Valve Mark" GB12220. Ku valve iijisi nguzu zyakubeleka ziinda ku 1.0MPa alimwi ilaa mulimo wakukosola payipi mpati, kusunkwa kwanguzu akubeleka kabotu kweelede kuchitwa kakutanabikkwa, mpawo ilazumizigwa kubelesegwa nikwakainda musunko. Muchiindi chakusunkwa kwanguzu, nguzu zyakusunkwa zili 1.5 ziindi zyanguzu zyaambwa, mpawo chiindi tachili munsi aamaminiti aali 5. Busena bwamavalvu akupakila kweelede kuba kabotu kakunyina kuvwundauka. Mukusunkwa kwakujatikizigwa, kusinikizyigwa kwakusunka kuli ziindi zili 1.1 kwiinda kusinikizyigwa kwachiimo; muya wakusunka weelede kuzuzikizya ziyandikana zya GB50243 muchiindi chakusunka, mpawo busena bwakujala bwa valve buleelela kuti kakunyina kuvwundauka.

Twaambo twakusala zintu

1. Zibeela zipati zyakweendelezya zyavvalavu yabutterfly iikkede a rabanzintu zilembedwe abupati.

2. Ilakonzya kubelesegwa amaanza, magesi naakuti azipa, mpo ilakonzya kubikkwa mumbali aali 90°.

3. Akaambo ka shaft yomwe a valve plate yomwe, nguzu zyakunyamuna zili munsi, mpawo buumi bwa valve mbufwiifwi muchiimo chakusiyana kupati kwanguzu antoomwe akuvwula kwamaanzi.
