Kubelesya vvalavu ya butterfly a gate valve mubukkale bwiindene-indene bwakubeleka

Ivalvu yamulyango lubovalve ya butterfly zyoonse zibeleka mulimo wakusandula akubamba kweenda kwamapaipi. Masimpe, kuchili nzila yakusala nzila ya butterfly valve a gate valve. Mukuchitila kuchesya bulongo buvwumbidwe mumupaipi mumugwagwa wamaanzi, kanjikanji mapaipi mapati alabikkwa mavwili aabutterfly, alo aatakwe mpindu mpati kukuvwumbilila bulongo, mpawo asolekesya kusala mavwili aamulyango.

Ino nkwiindana nzi aakati ka butterfly valve a gate valve?

Kweelana amulimu akubelesegwa kwa vvalavu yamulyango a vvalavu ya butterfly, vvalavu yamulyango ilijisi nguzu zyakukasya kuzwa kwamaanzi mpawo ilakonzya kujala kabotu. Nkaambo kakuti nzila yakuzuza yachipulo chamulyango antoomwe achibelesyo chili akati-akati chili aangle iimvwi, ikuti chipulo chamulyango tiichandulwidwe aachipulo chamulyango, kusanzya chaakati-akati aapuleti lyamulyango kuyoopa kuti chipulo chamulyango chizungaane. , Nchuubauba kunyonyoona chisinkilizyo cha valve yamulyango. Ivalvu ya Butterfly, alimwi yiitwa kuti flap valve, ninzila imwi yeendelezya ilijisi bupange buuba. Ivalvu yabutterfly iikonzya kubelesegwa kujala akuzima kwamapaipi aatakwe nguzu zyamaanzi chaamba kuti chijala (disiki naakuti bbatterfly plate) nidisiki, iizungaana kuzyunguluka nkomo ya valve kuti ijalulwe akujala. Ivalvu iikonzya kubelesyegwa kweendelezya kweenda kwamaanzi aasiyene-siyene mbuli muya, maanzi, busi, zintu zisiyene-siyene zikonzya kubola, matope, mafuta, nsimbi zyamaanzi alimwi azintu zipa nguzu zya radioactive. Ikapati chibeleka mulimo wakugela akulesya mupayipi. Cibeela chakujalula akujala vvalavu yabutterfly nchintu chiboneka mbuli disiki, eeyo iizungaana kuzyunguluka ntalisyo yayo mumubili wavalvu kuchitila kuti izuzikizye makanze aakujalula akujala naakuti kubambulula. Ipuleti lyamubala weendelezegwa achisiko cha valve. Kuti yasika 90°, ilakonzya kumanizya kujalula akujala komwe. Kwiinda mukuchincha nzila yakuleya kwa disiki, kweenda kwachintu chili mukati kulakonzya kweendelezyegwa.

Ziimo zyakubeleka anzila yakubelesya: Ivalvu ya Butterfly ileelela kunyamuna zintu zisiyene-siyene zibola azintu zitabi muzintu zyakupanga-panga mbuli sikupanga, muya wamalasha, muya wacilengwaleza, muya wamafuta aajisi maanzi, muya wamunzi, muya uupya uutontola, kusungulula amakemikalu akupanga manguzu aakukwabilila busena, kuyobola maanzi mumayake, azimwi zili mumupaipi. bamba mpawo ulesye kweenda kwachintu chili akati-akati.

Ivalavu yamulyango ilijisi mulyango uujalula akujala, kweenda kwamulyango kuliimpene anzila yamaanzi, mpawo vvalavu yamulyango ilakonzya buyo kujalulwa akujalwa. Kusumpula kupanga kwayoor ikukonzya akuchita kuti kube kuzanduka kwabusena bwakujala muchiindi chakuchita, mulyango ooyu wiitwa kuti mulyango uukwabilila.

Eelyo vvalavu yamulyango noijalwa, busena bwakujala bulakonzya buyo kusyoma munguzu zili akati-akati kuti zijalwe, nkokuti, kusyoma buyo munguzu zyaakati-kati kuti zisinikizye busena bwakujala bwamulyango kuchibaka chamulyango kulubazu lumwi kuchitila kuti busena bwakujala bujalwe, oobo bulijala. Bunji bwamavwili aamulyango alajalwa chakusinikizya, nkokuti, eelyo mavwili naajalwa, mulyango weelede kusinikizyigwa kuchibbula chavalvu anguzu zyaanze kuchitila kuti busena bwakujala bujatikizyigwe.

Nzila yakweenda: Mulyango wamulyango wamulyango weenda mumuzila uululeme antoomwe achisiko chavalvu, eecho alimwi chiitwa kutiOS&Y vvalavu yamulyango. Kanjikanji, kuli nsinga zya trapezoidal aamusako wakunyamuna. Kwiinda mu nsingo iili atala aa vvalavu amugoti uusololela amubili wa vvalavu, kweendeenda kwakuzungaana kulasanduka kuba kweenda kwamulongo, nkokuti, nguzu zyakubeleka zilasanduka kuba nguzu zyakubeleka. Eelyo vvalavu noijalulwa, eelyo bulamfu bwamulyango nobuli mbuli 1:1 ziindi zyabwamba bwa vvalavu, nzila yamaanzi tiikonzyi kusinkililwa pe, pesi busena oobu tabukonzyi kulanganyigwa muchiindi chakubeleka. Mukubelesya kwini, mutwe wachisiko cha valve ubelesyegwa mbuli chitondezyo, nkokuti, aawo mpoutakonzyi kujalulwa, mbuli busena bwawo bujalukide. Kuti tubikkile maanu kukujala akaambo kakucinca kwakupya, kanjikanji kujalulwa kusika atala, mpawo kujokela ku 1/2-1 turn, mbuli busena bwa valve iijalukide. Aboobo, busena bwakujula buzulide bwa valve bulajanwa kweendelanya abusena bwamulyango (nkokuti stroke). Zimwi nzungu zyamulyango zilabikkwa amulyango, mpawo kuzungaana kwavwili lyamaanza kupa kuti ntambo yamulyango izungaane, eezi zipa kuti mulyango usumpuke. Musyobo ooyu wavalvu wiitwa kuti Rotary stem gate valve naakutiNRS vvalavu yamulyango.
