Kuli misyobo myiingi yamavalvu aabutterfly, alimwi kuli nzila zyiingi zyakwaandaanya.
1. Kwaandaanya kweendelana abupange
(1)vvalavu ya butterfly iijisilidi; (2) vvalavu ya butterfly yomwe; (3) zyobile-vvalavu ya butterfly iitalibonyi; (4) ntalisyo zyotatwe zya butterfly
2. Kwaandaanya kweendelanya azintu zyakujala atala
(1) Valve ya butterfly iisimide
(2) Ivalvu ya butterfly iijisilidwe kapati yamusyobo wabutale. Zijazyo zyobile zipangidwe azintu ziyumu zyabutale kuya kuzintu ziyumu zyabutale.
3. Kwaandaanya kwiinda mukujala
(1) Ivalvu ya butterfly yakajalilidwe kusinikizyigwa.
(2) Ivalvu yakujala bbaatafly. Ikusinikizyigwa kwakujala kulachitika akaambo kachintu chakujala chiyumu achibbula naakuti achipuleti.
(3) Ivalvu ya butterfly iijalilidwe alikke. Ikusinikizyigwa kwakusinkilila kulapangwa alikke akusinikizyigwa kwaakati-akati.
4. Kwaandaanya kweendelana akusinikizyigwa amulimu
(1) Ivacuum butterfly valve. Ivalvu ya Butterfly iijisi nguzu zyakubeleka zili munsi-munsi aamuwo uuzumizyidwe.
(2) Ivalvu ya butterfly iibelesya nguzu zyaansi. Ivalvu ya Butterfly iijisi nguzu zya PN≤1.6MPa.
(3) Ivalvu ya butterfly ibelesya nguzu zyaakati-kati. Ikusinikizya kwa PN nkuvwungulula kwa 2.5∽6.4MPa.
(4) Valve ya butterfly iijisi nguzu kapati. Ikusinikizya kwa PN nkuvwungulula kwa 10.0∽80.OMPa.
(5) Valve ya butterfly iijisi nguzu kapati. Ivalvu ya Butterfly iijisi nguzu zya PN <100MPa.
5. Kwaandaanya kweendelana anzila yakuswaangana
(1)Wafer butterfly valve
(2) Flange butterfly valve
(3) Lug butterfly valve
(4) Valve ya butterfly iijisilidwe
Ivalvu ya Concentric Butterfly ninzila imwi yavalvu iijula akujala achipuleti chabutterfly chizungulukide mpawo ilajalula, kujala akubamba nzila yamaanzi akuzungaana kwa valve stem. Ipuleti yabutterfly ya butterfly valve ibikkwa munzila ya diameter yapayipi. Munzila iili mbuli bbola yamubili wa vvalavu ya butterfly, bbwe lya butterfly lya disiki lilazungaana kuzyunguluka bbazu, mpawo nzila yakuzungaana ili akati ka 0 a 90. Eelyo kuzungaana nokwasika ku 90, vvalavu ilajaluka.
Twaambo tupati twakuyaka akubikka
1) Busena bwakubikkila, bulamfu, nzila yakunjizya akugwisya kweelede kweendelana aziyandikana, mpawo kujatana kweelede kuba kuyumu akuyuma.
2) Ijatisyo lyamisyobo yoonse yamavalvu aabelesyegwa amaanza aabikkidwe aamupayipi wakukwabilila kupya tayeelede kuba ansi pe.
3) Ivalvu yeelede kulanga-langwa anze kaitanabikkwa, mpawo zina lya valvu lyeelede kuzuzikizya zyeelelo zyamulawu wanyika yoonse "General Valve Mark" GB 12220. Kumavalvu ajisi nguzu zyakubeleka ziinda ku 1.0 MPa akukosola payipi mpati, kusima akubeleka kabotu kweelede kuchitwa kakutanabikkwa mpawo kubelesegwa. Mukusunkwa kwanguzu, kusinikizyigwa kwakusunka kuli ziindi zili 1.5 kwiinda kusinikizyigwa kwakuyeeyela, mpawo chiindi tachili munsi aamaminiti aali musanu. Chikwabilizyo cha valve antoomwe akupaka kweelede kuti kachili kabotu kakunyina kuvwundauka. Kusunkwa kwakujatikizigwa, musunko wakusunka uli 1.1 ziindi zya musunko uuzyibidwe; muya wakusunka weelede kuzuzikizya GB 50243 muchiindi choonse chakusunka, mpawo busena bwakujala vvalavu buleelela.
Kusala zintu zyakusambala kwa twaambo tupati
1. Zibeela zipati zyeendelezya vvalavu ya butterfly nzintu zilembedwe abupati bwazyo.
2. Ivalvu ya butterfly ninzila yomwe yakubelesya muwo, bupange bwayo buuba, ilakonzya kubelesegwa kabotu, taiyandiki mali manji, ibelesegwa kabotu, pesi kuchincha kwacho takuli kabotu pe, kweelela biyo kubelesya nzila yakunjizya muya akutontozya muuya kuti ichinche naa kuchincha kwachiindi chifwiifwi.
3. Ulakonzya kubelesegwa amaanza, magesi naakuti kubelesya zipper, ulakonzya kubamba kufumbwa Angle ya 90 range.
4. Akaambo kakuti bbaaji lyomwe lyaatala lyomwe, nguzu zyakunyamuna zili munsi, muchiimo chakusiyana kupati kwanguzu, kweenda kupati aawo buumi bwakubelesya bbaala nobufwiifwi. Ivalvu ilijisi musyobo uujalilidwe amusyobo wabuzubaa buzuba, kukwabilila akutakwabilila.
5. Ivalavu yamagesi ilijisi buyo bweendelezi bwamisyobo yobile, ibelesya magesi ilikozyenye aalavu lyamafwaafwi manji.
