Ino mavalvu aabutterfly abelekela biyeni?

Valve ya Butterflyninzila imwi ya valve iibelesya chibeela chakujalula akujala kwa disiki kujokolosya a 90° kujalula, kujala naakuti kuchincha mweelwe wamaanzi aamukati. Butterfly valve taili buyo aabupange buuba, bupati buniini, buteteete, butebelesyi zintu zisyoonto, bupati busyoonto bwakubikka, nguzu zyakweenzya zisyoonto, kubeleka kuuba alimwi akufwambaana, pele alimwi ilijisi mulimo mubotu wakulanganya kweenda kwamaanzi alimwi akujala bube bwakujala, alimwi njiimwi yamisyobo ya valve iikomena kapati mumyaka iili kkumi yainda. Mavalvu aa butterfly alabelesyegwa kapati. Kusiyana amweelwe wakubelesya kwawo kuzumanana kuyaambele, akuyaambele kusika kukupya kupati, kusinikizyigwa kupati, bupati bupati, kujatilila kupati, buumi bulamfwu, bube bwakweendelezya bubotu, alimwi amilimo minji ya valve yomwe. Kusyomeka kwayo azimwi zitondezyo zyakubeleka zyasika aawo mpozigolela.

Akubelesya nsimbi iitakwe misamu iikolamavwili aabutterfly, kuchita kwamavwili aabutterflyyakasumpulwa. Nkaambo kakuti raba yakupanga ilijisi bube bwakukazya kubola, kutabola, kutazungaana, kutazungaana kubotu, kuuba kupanga, kutadula, azimwi, raba yakupanga iijisi bube bwiindene-indene ilakonzya kusalwa kweendelanya aziyandikana zyakubelesya ziindene-indene kutegwa izuzikizye bukkale bwakubeleka bwamavwili aabutterfly.

Nkaambo kakuti polytetrafluoroethylene (PTFE) ilijisi nguzu zyakukazya kubola, ibeleka kabotu, taikatazyi pe kuchembaala, ilijisi nguzu zyakuzwangana, nchuubauba kupanga, ilakkalilila mubupati, alimwi ilakonzya kusumpula bube bwayo kwiinda mukuzuzya akuyungizya zintu zyeelede, zibelesyo zyakujala vvalavu zili anguzu zibotu alimwi akubula nguzu zyakuzwangana, zilakonzya kujanwa akulesyegwa raba yakupanga ilazundwa, aboobo zintu zya polymer polymeric ziimininwa a PTFE antoomwe azintu zyakasandulwa zyakuzuzya zyakabelesegwa kapati mu butterfly valve, aboobo kubeleka kwa butterfly valve kwasumpuka.Mavalvu aabuteteantoomwe akupya akusinikizyigwa kwaandeene, kujala kusyomeka abuumi bulamfwu bwakubeleka zyakabambwa.

Kuti tuzuzikizye ziyandikana zyakubelesya mumafakitali mbuli kupya kapati akutontola, kuvwuuma kwanyika, abuumi bulamfwu, mavalvu aabutterfly seal butterfly akapangwa kapati. Akubelesya nzila zyakukazya kupya kupati, kukaka kupya kusyoonto, kukwabililwa kukubola, kukwabililwa kukunyonyooka, antoomwe azintu zya alloy ziyumu kapati mumavalvu aabutterfly, mavalvu aa butterfly aajalidwe abutale akabelesyegwa kapati mumakwebo mbuli kupya kapati akutontola, kupya kupati, abuumi bulamfwu, alimwi amavalvu aabutterfly aajisi bupati bupati (~7050), pressure mpati (~750 MP). antoomwe akupya kupati (-196~606°C) kwakalibonya, aboobo busongo bwamavwili aabutterfly bwasika aawo mpobugolela.

Eelyo vvalavu ya butterfly niyajalulwa, ilaa nguzu zyakulesya kweenda. Eelyo kujaluka kuli akati ka 15°~70°, kulakonzya kubelesegwa kweendelezya kweenda kwamaanzi, aboobo kubelesya vvalavu ya butterfly nchintu chidumide loko mumulimo wakubamba bupati.

Akaambo kakuzungaana kwachipulo cha butterfly valve butterfly plate, ma butterfly valve manji alakonzya kubelesegwa kubamba zintu ziyumu. Kweelana anguzu zyachisinkilizyo, chilakonzya kubelesegwa akupanga zintu zijisi busi.

Mavalvu aa butterfly alakonzya kweendelezya kweenda kwamaanzi. Nkaambo kakuti kusweekelwa kwanguzu kwa valve ya butterfly mupayipi nkupati, ziindi zyotatwe kwiinda kwa gate valve, notusala butterfly valve, nsungwaazyo yakusweekelwa kwa pressure ya nzila ya paipi yeelede kulanga-langwa, mpawo manguzu aa butterfly plate kuti akonzye kunyamuna muya wa paipi aawo nuujalidwe ayelede kulanga-langwa. Mukuyungizya, kulezya kwakupya kwakubeleka ooko chibbula cha elastomeric nchochikonzya kubikkwa muchiindi chakupya kapati kweelede kubikkilwa maanu.

Ivalvu ya butterfly ilijisi bulamfwu busyoonto bwakuyakwa abulamfwu boonse, ilafwambaana kujalula akujala, alimwi ilaa bube bubotu bwakweendelezya maanzi. Njiisyo yabupange bwamavalvu aabutterfly njiyeelela kapati mukupanga mavalvu aamabbanga mapati. Eelyo vvalavu ya butterfly niyayandika kubelesyegwa kweendelezya mweelwe wamaanzi, nchintu chibotu kusala bupati amusyobo weelede wa vvalavu ya butterfly kuchitila kuti ibeleke kabotu.

Kanjaanji, mukweendelezya, kweendelezya antoomwe abulongo, bulamfwu bwachiyaka mbufwiifwi, kujalula akujala kufwambaana, mpawo kugonkwa kwanguzu ziniini (kwiindana kusyoonto kwanguzu) kulayandika, mpawo vvalavu ya butterfly ilalumbaizigwa. Mavuluvu aa butterfly alakonzya kubelesegwa aawo kakuli kuchincha kwazibeela zyobile, nzila yacheya, muzuzumo muniini, kuvwuuma akuvwuuma, kuvwundauka kusyoonto mumulengalenga, antoomwe azintu zikonzya kukwasula. Muchiimo chakubeleka chilibedelede, kuchincha kwakujala, naa kujala changuzu, kusama kupati, kupya kusyoonto (cryogenic) azimwi ziimo zyakubeleka.
