Ivaluvu yamuwoilijisi chintu chibelesya muuya antoomwe a vvalavu iitegwa butterfly. Ivaluvu yamuwo ibelesya bbwe lyamuwo lizunguluka achisiko chavalvu kuti lijalulwe akujala, kuchitila kuti lichite mulimo wakutalisya. Ivalavu yamuwo ibelesyegwa kapati mbuli vvalavu yakujala, alimwi ilakonzya kuchitwa kuti ibe amulimu wakubambulula naakuti vvalavu yakugwisya akubamba. Kwalino, vvalavu lyabutterfly lilabelesyegwa mumaanzi masyoonto alimwi lipati lilabelesyegwa kapati mumapaipi aajisi bulo bwaakati-kati.
Njiisyo yakubeleka yavvalavu yamuwo
Ipuleti yabutterfly ya butterfly valve ibikkwa munzila yabwamba bwamupayipi. Munzila iili mbuli bbola lyamubili wa bbatani, bbwe lya butterfly lili mbuli disiki lilazungaana kuzyunguluka ntalisyo, mpawo mweengwe wakuzyunguluka uli akati ka 0°-90°. Eelyo kuzungaana kwasika ku 90°, vvalavu ilimuchiimo chakujula. Ivalvu yabutterfly njiubauba mubupange, niini mubupati mpawo njiini mubulemu, mpo ilijisi buyo zibeela ziche. Kwiindawo, ilakonzya kujalulwa akujalwa chakufwambaana kwiinda mukuzungaanya buyo 90°, mpawo nzila eeyi njiubauba. Aawo awo, vvalavu ilijisi bube bubotu bwakweendelezya maanzi. Eelyo vvalavu yabutterfly noili muchiimo chijalukide, bupati bwabbatterfly plate mbobukonzya kukazya aawo akati-kati nikwiinda mumubili wavalvu, aboobo kudonkola kwanguzu kuchitwa avalvu nkusyoonto loko, aboobo ilijisi bube bwakweendelezya kweenda kabotu. Mavalvu aa Butterfly alijisi nzila zyobile zyakujala: chijazyo cha elastic achijazyo chabutale. Kumavwili aakujala aajisi nguzu, nkomo yakujala ilakonzya kubikwa amubili wamavwili naakuti kujatikizyidwe kumbali aapuleti lyabutterfly.
Ivalvu yamuwokubamba akugwisya tumpenda
1. Nzila yakulanga-langa akubamba masilinda
Chiindi chiingi kochita mulimu mubotu wakusalazya atala aachikwabilizyo akunanika mafuta kuchizyungulukilo chachikwabilizyo. Jula chivwumbyo chakumamanino chachibbeeke lyoonse mumyezi iili 6 yoonse kuchitila kuti ubone naa kuli zintu zisiyene-siyene abuteteete muchibbeeke, antoomwe abukkale bwamafuta. Kuti mafuta aakusanzya kaaliwo naakuti akayuma, nkuko kuyandika kuti silinda agwisyigwe kuchitila kuti kube kubambululwa akusalazyigwa kakutanabikkwa mafuta aakusanzya.
2. Kulanga-langa mubili wavalvu
Amwi myezi iili 6, langa naa mubili wa valve ulibonya kabotu, naa kuli kuvwundauka a flange yakubikkila, ikuti naa kacili kabotu, langa naa cisinkilizyo ca valve cili kabotu, kunyina kusama, naa cibulo ca valve cilakonzya kuzungaana, alimwi akuti naa kuli cintu cili coonse cimbi cijatikizyidwe mu valve.
Nzila zyakugwisya akubunganya bbuloki lya cylinder anzila zyakucenjela:
Kusaanguna gwisya silinda kuzwa kumubili wa vvalavu, sanguna gwisya chivwumbyo kumamanino oonse obile aa silinda, bikkila maanu kunzila ya piston rack aawo nogwisya piston, mpawo kobelesya nguzu zyaanze kuzungaanya chisiko cha silinda kuya kulubazu lwawoola kuchitila kuti piston iunke kulubazu lwaanze, mpawo ujale vvalavu. weelede kubikkila maanu kukunjizya muya asyoonto-syoonto, ikuti naa tiikwaba boobo piston ilakonzya kuzwa, eezi zilaa ntenda! Mpawo gwisya chikwabilizyo chili aachikobela cha silinda, mpawo chikozyano cha silinda chilakonzya kujalulwa kuzwa kumamanino aambi. chigwisye. Mpawo ulakonzya kusalazya chibeela chimwi achimwi mpawo ubike mafuta. Zibeela zyeelede kubikkwa mafuta nzizyeezyi: bwaanda bwamukati bwasilinda antoomwe a ringi yakujala pistoni, chibikkilo antoomwe a ringi yakusyule, antoomwe a gear shaft an ringi yakujala. Musule akusanzya mafuta, ayelede kubikwa kweendelanya abubambe bwakugwisigwa anzila yakujokela musule yazibeela. Kuzwa waawo, yeelede kubikwa kweendelanya akutobelana kwakugwisigwa antoomwe akutobelana kwazibeela. Kobikkila maanu kubusena bwagiya achibikkilo, mpawo ubone kuti pisitoni yacheya kusika kubusena aawo vvalavu noijalukide. Mulyango uuli kumamanino aagiya ulakozyanya a bbuloki lya silinda muchiindi chamukati loko, mpawo mulyango uuli kumamanino aagiya uliimvwi nji a bbuloki lya silinda eelyo pisitoni niyatandabikwa kuya kunze loko aawo vvalavu niyajalwa.
Kubikkwa kwa cylinder a valve alimwi anzila zyakugwisya tumpenda alimwi anzila zyakucenjela:
Chakusanguna bikka vvalavu muchimo chakujalila anguzu zyaanze, nkokuti, kojokezya vvalavu kuya kulubazu lwawoola kusikila ipuleti lya vvalavu lijatane achuuno cha vvalavu, mpawo aawo mpobika vvalavu muchiimo chakujala (nkokuti, vvalavu nsyoonto iili atalaa ntambo yasilinda. silinda kuya ku vvalavu (nzila yakubikka ilakonzya kweendelana naakuti iliimvwi nji amubili wa vvalavu), mpawo ubone naa zibulo zyazikulukulu zili kabotu. Kuzanduka kupati, ikuti kakuli kuzanduka kusyoonto, kojokezya biyo bbuloki lya silinda mbichani, mpawo ujatisye zikulukulu zya Pneumatic butterfly valve kusaanguna kulangisisya kuti naa mavalvu ali kabotu. muffler, azimwi, kuti kazitazulide pe, utagwisyi tumpenda, muya uuli kabotu ngu 0.6MPA±0.05MPA, kotana belesya, kosinizya kuti taakwe tombe lyakajatikizyidwe mubbokesi lya valve mumubili wa valve Kumatalikilo aakubelesya akubelesya, kobelesya bbatani lyakubelesya amaanza lya solenoid valve (solenoid valve coil ilazimwa muchiindi chakubeleka amaanza, mpawo kubelesya amaanza kulabeleka; aawo magesi nabelesyegwa, kuzungaanya kwamaanza kulabikkwa a 00 mpawo coil ilazima, mpawo kubeleka kwamaanza kulabeleka; 0 busena 1 nkujala vvalavu, 1 nkujalula vvalavu, nkokuti, vvalavu ilajalulwa aawo magesi naajulwa, mpawo vvalavu ilajalwa aawo magesi naazima.
Kuti kwajanika kuti sikupanga mavwili aamuwo ulachedwa loko aawo mpokutalikila kujalula mavwili muchiindi chakutalisya akubeleka, pesi ulafwambaana loko mbuli mbwaazwa. Chakufwambaana, muchiimo eechi, vvalavu ilijalilidwe loko, kochincha biyo ntambo ya silinda mbichaani (sandula zikulukulu zyakusandula ntalisyo kumagolelo oonse obile aa silinda asyoonto achiindi chomwe, aawo nolibamba, vvalavu yeelede kunyangwa aawo mpoijulidwe, mpawo muya weelede kuzima. Uzime mpawo uchinche kusikila vvalavu ijaluke mubusena kakunyina kuvwundauka. Ikuti muffler kalakonzya kuchinchululwa, kuchincha kwa vvalavu kulakonzya kuchinchululwa. Nchintu chiyandikana kuti muffler uchinche kuti ujalulwe kabotu kuti vvalavu ichinche. Kuti kuchincha kakuli kusyoonto loko, ivalvu ilakonzya kutabeleka.
