Ntalisyo ya Butterfly Valve

Kuzibisya:

Ivalvu ya butterflyuzwa mumpuli yamavwili aaitwa kutimavwili aazunguluka kota. Mukubeleka, vvalavu ilajaluka naakuti kujalwa aawo disiki nolizungaanisigwa kota. "Chiyuni" nchikozyano chabutale chibikkidwe amusako. Eelyo vvalavu noijalwa, disiki lilasandulwa kuchitila kuti lijale nzila. Eelyo vvalavu nolijalukide, disiki ilazungaanisigwa kota yakujokela kuchitila kuti izumizye kweenda kwamaanzi kakunyina kulesyegwa. Ivalvu ilakonzya kujalulwa mbichaani kuchitila kuti maanzi azwe.

Kuli misyobo isiyene yamavalvu aabutterfly, umwi awumwi ulakonzya kubelesegwa munzila zisiyene akubelesegwa kusiyene. Ivalvu ya butterfly iitakwe mpindu, eeyo ibelesya kuchincha kwa raba, njiijisi nguzu zyaansi kapati. Ivalvu yabutterfly iibeleka kabotu loko, iibelesyegwa muma system aajisi nguzu zyiingi, ilagwisigwa kuzwa akati-kati kachibbula chadisiki akujala mubili (kugwisigwa komwe), antoomwe amuzila waakati-kati wabbola (kugwisigwa kwabili). Eezi zipa kuti kube kuchita kwa cam muchiindi chakubeleka kuchitila kuti chibbula chigwisye muchikwabilizyo mpawo eezi zipa kuti kutabi kuzwangana kusyoonto kwiinda mbokwakachitwa munzila ya zero offset mpawo kuchesya kusama kwacho. Ivalvu iikonzya kubelesegwa kapati muma system aajisi muya mupati ni valve ya triple offset butterfly. Muchivulu eechi, ntalisyo yachibbula chadisiki iliimpene, eeyo ichita kuti kutabi kujatana aakati kachibbula achibbula. Muchiimo cha mavalvu otatwe, chibbula chakabambwa abutale kuchitila kuti chikonzye kuchitwa mbuli kuti chijale bubble tight shut-off aawo nochiswaangana a disiki.

Misyobo

1. Mavalvu aabutterfly aatakwe ntenda– musyobo ooyu wa vvalavu ulaa chibbula cha raba chiyumu chilaa disiki lyabutale.
2. Mavalvu aabutterfly aajisi zibeela zyobile(mavwili aabeleka obotu naakuti mavwili aajisi zibeela zyobile) – zibelesyo zisiyene-siyene zibelesyegwa kupanga chibbula achibbula.
3. Mavalvu aabutterfly aajisi zibeela zyotatwe(mavwili aajisi zibeela zyotatwe) – zyuuno zilakonzya kuba aama laminate naa zipangidwe abutale buyumu.

Mavalvu aabutterfly aamusyobo wa wafer

Chiwafer style butterfly valveyakabambilwa kuti ikwabilile kukwabililwa kuzwa kukusiyana kwanguzu zyamabazu obile kutegwa kutabi kujokela musyule munzila zyakabambilwa kuzuza kwamaanzi munzila yomwe. Chilazuzikizya eezi achisinkilizyo chijatikizyidwe kabotu; nkokuti, gasket, o-ring, yakapangwa kabotu-kabotu, alimwi abusyu bwa valve bupapalete kumabazu aakujulu alimwi aansi aa valve.

Lug-style butterfly valve

Mavalvu aamusyobo wa Lugzilijisi ntambo zyakunjizya kumabazu oonse obile aamubili wavalvu. Eezi zipa kuti zibikkwe munzila ibelesya mabbaulu obile kakunyina nzungu. Ivalvu ilabikkwa aakati kamafuleji obile kubelesya mabboluti aandeene kuli flange imwi aimwi. Ooku kubamba kupa kuti lubazu lumwi lomwe lwanzila yamapayipi lugwisyigwe kakunyina kunyonganya lubazu lumwi.

Ivalvu ya lug-style butterfly iibelesyegwa mumulimo uutalibonyi kanjikanji ilaa nguzu zyakucheya. Mbuli chitondeezyo, lug-style butterfly valve iibikkidwe aakati kama flange obile ilijisi 1,000 kPa (150 psi) pressure rating. Ivalvu njiyonya yakabikkidwe a flange yomwe, mumulimo uutagoli, ilijisi 520 kPa (75 psi) mweelwe. Mavwili aajisi mabbaaji alakonzya kukazyigwa kapati amakemikalu alimwi azintu zipa kuti zintu zibe kabotu alimwi alakonzya kuzumanana kupya kusikila ku 200 °C, calo cipa kuti ube nzila iikonzya kubelesyegwa munzila ziindene-indene.

Kubelesya mumakwebo

Mumakwebo aamisamu, makemikalu, azyakulya, vvalavu ibelesyegwa kulesya kweenda kwazintu (ziyumu, maanzi, muya) mukati kamulimo. Mavalvu abelesyegwa mumakkampani aaya kanjikanji akapangwa kweendelana amalailile aa cGMP (nzila mbotu yakupanga zintu). Mavalvu aabutterfly kanjikanji akanjila mubusena bwama ball valve mumakkampani miingi, ikapati mafuta, akaambo kakudula akuubauba kwakubikka, asi mapaipi ajisi mavalvu aabutterfly taakonzyi 'kubikkwa' kuti asalazyigwe.
