Nsinya wa nawu wa ntirho na ndlela yo hlayisa na ku lulamisa swihoxo ya valve ya phaphatani ra moya

Valve ya phaphatani ra moyayi vumbiwa hi xitirhisiwa xa moya ni valve ya phaphatani. Valve ya pneumatic butterfly yitirhisa xirhendzevutani xa butterfly plate leyi rhendzelekaka na nsinya wa valve kuva yi pfula naku pfala, leswaku yita lemuka xiendlo xa activation. Valve ya pneumatic yitirhisiwa ngopfu tani hi valve yo pfala, naswona yinga tlhela yi endliwa kuva na ntirho wa adjustment kumbe section valve na adjustment. Sweswi, valve ya phaphatani yitirhisiwa eka ntshikelelo wale hansi naswona yikulu Yitirhisiwa ngopfu eka tiphayiphi ta medium-bore.

Nsinya wa nawu wa ntirho wavalve ya phaphatani ra moya

Puleti ya phaphatani ya valve ya phaphatani yi vekiwa eka tlhelo ra diameter ya phayiphi. Eka xiteji xa cylindrical xa miri wa valve ya phaphatani, pulati ya phaphatani leyi nga na xivumbeko xa disc yi rhendzeleka ku rhendzela axis, naswona angle yo rhendzeleka yi le xikarhi ka 0°-90°. Loko ku rhendzeleka ku fika eka 90°, valve yi le ka xiyimo lexi pfulekeke hi ku helela. Valve ya phaphatani yi olovile hi xivumbeko, yitsongo hi vukulu naswona yi vevuka hi ntiko, naswona yi na swiphemu swi nga ri swingani ntsena. Ku tlula kwalaho, yi nga pfuriwa ni ku pfala hi ku hatlisa hi ku rhendzeleka ntsena hi 90°, naswona vuhandzuri bya kona bya olova. Hi nkarhi lowu fanaka, valve yina swihlawulekisi swa kahle swa vulawuri bya mati. Loko valve ya phaphatani yiri eka xiyimo lexi pfulekeke hiku hetiseka, ku enta ka butterfly plate hi kona ntsena ku lwisanaka loko medium yi khuluka hi miri wa valve, hikokwalaho kuhunguteka ka ntshikelelo loku endliwaka hi valve i kutsongo swinene, hikokwalaho yina swihlawulekisi swa kahle swa vulawuri bya ku khuluka. Ti valve ta maphaphatani tina tinxaka timbirhi to pfalela: elastic seal na metal seal. Eka ti elastic sealing valves, sealing ring yinga nghenisiwa eka miri wa valve kutani yi khomanisiwile na matlhelo ya butterfly plate.

Valve ya phaphatani ra moyaku hlayisiwa na ku lulamisa swihoxo

1. Pulani yo kambela na ku hlayisa silindara

Hi ntolovelo endla ntirho wa kahle wo basisa vuandlalo bya cylinder naku chela mafurha eka circlip ya cylinder shaft. Pfula xifunengeto xa makumu xa cylinder nkarhi na nkarhi endzhaku ka tinhweti tin’wana na tin’wana ta 6 ku kambela loko kuri na ti sundries na ndzhongho eka cylinder, na xiyimo xa mafurha. Loko mafurha yo tola ya kayivela kumbe ya omile, swa laveka ku hahlula silindara kuva yi hlayisiwa hiku hetiseka naku basisiwa loko kungase cheriwa mafurha yo tola.

2. Ku kamberiwa ka miri wa valve

Endzhaku ka tinhweti tin’wana na tin’wana ta 6, languta loko ku languteka ka miri wa valve ku ri kahle, loko kuri na ku vupfa eka flange yo khandziya, loko swi olova, languta loko seal ya miri wa valve yi ri kahle, kungari na ku onhaka, loko valve plate yi olova, na loko kuri na swilo swa matiko mambe leswi khomiweke eka valve.

Maendlelo yo hambanyisa na ku hlanganisa ti cylinder block na switsundzuxo:

Xosungula susa silindara eka miri wa valve, rhanga hi ku susa xifunengeto emakumu hamambirhi ya silindara, nyikela nyingiso eka tlhelo ra rhaki ya piston loko u susa piston, kutani u tirhisa matimba yale handle ku rhendzeleka na shaft ya cylinder hi tlhelo ra wachi ku endla leswaku piston yi tsutsuma kuya eka tlhelo rale handle swinene, kutani u pfala valve Xirhendzevutani xi nghenisiwa moya hiku nonoka naswona piston yi susumetiwa ehandle hiku olova hi ntshikelelo, kambe ndlela leyi yifanele ku nyikela nyingiso eka nghenisa moya hi ku nonoka, handle ka sweswo piston yi ta huma hi xitshuketa, leswi nga ni khombonyana! Kutani susa circlip eka cylinder shaft, naswona cylinder shaft yinga pfuriwa kusuka eka makumu yan’wana. yi humesa. Kutani u nga basisa xiphemu xin’wana ni xin’wana ivi u chela mafurha. Swiphemu leswi lavaka ku cheriwa mafurha hi leswi: rirhangu ra le ndzeni ra silindara na ring ya piston seal, rack na ring yale ndzhaku, xikan’we na gear shaft na seal ring. Endzhaku ko tota girisi, yifanele ku vekiwa kuya hi ku landzelelana ka ku hahluka na ku landzelelana loku tlheriseriweke endzhaku ka swiphemu. Endzhaku ka sweswo, yifanele ku vekiwa kuya hi ku landzelelana ka ku hahluriwa na ku landzelelana loku tlheriseriweke endzhaku ka swiphemu. Nyikela nyingiso eka ndzhawu ya gear na rack, naswona tiyisisa leswaku piston yi hunguteka kuya eka ndzhawu loko valve yi pfulekile. Groove yale makumu yale henhla ya gear shaft yi fambelana na cylinder block hinkarhi wa xiyimo xale ndzeni swinene, naswona groove eka makumu yale henhla ya gear shaft yi perpendicular eka cylinder block loko piston yi olovisiwile kuya eka xiyimo xale handle swinene loko valve yi pfariwile.

Ku vekiwa ka miri wa silindara na valve na tindlela to lulamisa swihoxo na switsundzuxo:

Xosungula veka valve eka xiyimo xo pfala hi matimba yale handle, hi leswaku, jikajika shaft ya valve kuya eka clockwise kufikela loko valve plate yiva eka sealing contact na xitulu xa valve, naswona hi nkarhi lowu fanaka veka cylinder eka xiyimo xo pfala (hileswaku, valve leyintsongo ehenhla ka cylinder shaft Groove yi perpendicular eka miri wa cylinder (eka valve leyi rhendzelekaka clockwise ku pfala valve), kutani u nghenisa cylinder kuya eka valve (ndlela yo veka yi nga va parallel kumbe perpendicular na miri wa valve), ivi u kambela loko ti screw holes ti aligned Large deviation, loko ku ri na ku hambuka nyana, ntsena jikajika cylinder block nyana, ivi u tiyisisa swikwirikiri Pneumatic butterfly valve debugging rhanga u kambela loko switirhisiwa swa valve swi vekiwile hi ku helela, solenoid valve na muffler, etc. unga debug, ntshikelelo wa moya wa mphakelo wa ntolovelo i 0.6MPA±0.05MPA, loko u nga si tirha, tiyisisa leswaku a ku na thyaka leri khomiweke eka pulati ya valve emirini wa valve Eka ku khomixini ko sungula na ku tirha, tirhisa buti yo tirha hi voko ya valve ya solenoid (khoyili ya valve ya solenoid yi timiwile hi nkarhi wa ku tirha hi voko, naswona ku tirha hi voko swi tirha; loko ntirho wa vulawuri bya gezi wu endliwile, ku soholota hi voko ku vekiwa eka 0 naswona khoyili yi timiwile, naswona ntirho wa manual wu tirha; 0 xiyimo xa 1 i ku pfala valve, 1 i ku pfula valve, hi leswaku, valve yi pfuriwa loko gezi ri pfuriwile, naswona valve yi pfala loko gezi ri timiwile.

Loko swikumeka leswaku muendli wa valve ya pneumatic butterfly u nonoka swinene eka ndzhawu yosungula ya ku pfuleka ka valve hinkarhi wa commissioning naku tirha, kambe yi hatlisa swinene hiku hatlisa loko yi famba. Hi ku hatlisa, eka xiyimo lexi, valve yi pfariwile swinene, lulamisa ntsena stroke ya cylinder nyana (lunghisa swikwirikiri swo lulamisa stroke emakumu hamambirhi ya silindara nyana hi nkarhi wun’we, loko u lulamisa, valve yifanele ku yisiwa eka ndzhawu leyi pfulekeke, kutani xihlovo xa moya xifanele ku timiwa Yi time kutani yi lulamisa), lulamisa kufikela loko valve yi olova ku pfula no pfala endhawini ya yona handle ko vupfa. Loko muffler yi lulamisiwa, rivilo ro cinca ra valve ringa lulamisiwa. Swifanele ku lulamisa muffler kuya eka ku pfuleka loku faneleke ka rivilo ro cinca valve. Loko ku lulamisiwa ku ri kutsongo swinene, valve yi nga ha va yi nga tirhi.
