Itandukaniro riri hagati ya O-umupira wumupira na V-umupira wumupira.

Umupira

Hariho ubwoko bwinshi bwimiterere yimipira, ariko mubyukuri ni bimwe.Byose ni imipira yumupira ibice byo gufungura no gufunga bizengurutse.Zigizwe ahanini nintebe ya valve, umuzingi, impeta yo gufunga, stem stem nibindi bikoresho byo gutwara.Igiti cya valve kizunguruka dogere 90 kugirango ugere Gufungura no gufunga valve ikoreshwa kumuyoboro kugirango uhagarike, gukwirakwiza, guhindura igipimo cyoguhindura no guhindura icyerekezo cyogutwara.Intebe ya valve ikoresha uburyo butandukanye bwo gufunga intebe ukurikije imikorere itandukanye.Imbere ya valve yumubiri wa O-umupira wumupira ni umuzingi ufite hagati unyuze mu mwobo.Umuzingi ufite umwobo unyuze hamwe na diameter ingana na diameter y'umuyoboro.Umuzingi urashobora kuzunguruka mu ntebe ya kashe.umubiri kugirango ugere kashe.Umupira wumupira wubwoko bwa V ubwoko bwumupira ufite imiterere ya V.Intanga ya valve nigice cya 1/4 cyikigina hamwe na V.Ifite ubushobozi bunini bwo gutembera, intera nini ishobora guhinduka, gukata imbaraga, no gufunga cyane.Ibikoresho bifite imiterere ya fibrous.

O-umupira wumupira:

Imbere ya valve yumubiri wa O-umupira wumupira ni umuzingi ufite hagati unyuze mu mwobo.Umuzingi ufite umwobo unyuze hamwe na diameter ingana na diameter y'umuyoboro.Umuzingi urashobora kuzunguruka mu ntebe ya kashe.umubiri kugirango ugere kashe.Muguhinduranya umupira 90 °, icyerekezo cyanyuze mu mwobo kirashobora guhinduka, bityo ukamenya gufungura no gufunga umupira wumupira.O-ubwoko bwumupira wa valve ifata igishushanyo kireremba cyangwa gihamye, kandi ibice bigenda byimuka bikozwe mubikoresho byo kwisiga hamwe na coefficient ntoya cyane, bityo torque ikora ni nto.Byongeye kandi, gufunga igihe kirekire amavuta yo gufunga bituma imikorere ihinduka.Ibyiza byibicuruzwa nibi bikurikira:

1.O ubwoko bwumupira wumupira ufite imbaraga nke zo kurwanya amazi

Imipira yumupira muri rusange ifite ibice bibiri bya diameter no kugabanya diameter.Ntakibazo cyaba kimeze gute, coeffisente yo kurwanya umuvuduko wumupira wumupira ni muto.Umupira usanzwe wumupira nubwoko bugororotse, bizwi kandi nkubwoko bwuzuye bwimipira.Diameter y'umuyoboro ingana na diametre y'imbere y'umuyoboro, kandi igihombo cyo kwihanganira ni ukurwanya gusa guhuza imiyoboro y'uburebure bumwe.Mubibaya byose, iyi ball ball ifite byibura irwanya amazi.Hariho uburyo bubiri bwo kugabanya ubukana bwa sisitemu y'imiyoboro: imwe ni ukugabanya umuvuduko w'amazi wongera diameter ya pipe na valve, bizamura cyane ibiciro bya sisitemu y'imiyoboro.Iya kabiri ni ukugabanya kurwanya kwimbere ya valve, kandi umupira wumupira nihitamo ryiza.

2.O-ubwoko bwa ball valve ihindura byihuse kandi byoroshye

Umupira wumupira ukeneye gusa kuzunguruka 90 ° kugirango urangize gufungura byuzuye cyangwa gufunga byuzuye, bityo birashobora gufungurwa no gufungwa vuba.

3. O ubwoko bwumupira wumupira ufite imikorere myiza yo gufunga

Umubare munini wintebe yimipira ikozwe mubikoresho byoroshye nka PTFE, mubisanzwe byitwa imipira yoroheje ifunze.Umupira woroheje ufunze umupira ufite imikorere myiza yo gufunga, kandi ibisabwa kugirango uburangare hamwe nuburyo bukoreshwa neza muburyo bwo gufunga hejuru ya valve ntabwo biri hejuru cyane.

4. O-ubwoko bwumupira wumupira ufite ubuzima burebure

Bitewe nuburyo bwiza bwo kwisiga amavuta ya PTFE cyangwa F4, coefficient de fraisse hamwe nizunguruka ni nto.Bitewe nubuhanga bunoze bwo gutunganya, ubukana bwumupira buragabanuka, bityo bikazamura cyane ubuzima bwa serivisi ya valve yumupira.

5. O-ubwoko bwumupira wumupira ufite ubwizerwe buhanitse

Ikirangantego cyo gufunga hagati yumupira nintebe ya valve ntizigera ibabazwa no gushushanya, kwambara byihuse nibindi byananiranye;

Nyuma yikibabi cya valve gihinduwe muburyo bwubatswe, impanuka yihishe ko igiti cya valve gishobora kuguruka kubera irekurwa rya glande ipakira bitewe nigitutu cyamazi kiravaho;

Umuyoboro wumupira ufite anti-static kandi urwanya umuriro urashobora gukoreshwa mumiyoboro yo gutwara peteroli, gaze gasanzwe na gaze.Icyuma cya valve (umupira) wa O-ball ball yo mu bwoko bwa O.Duhereye ku miterere, intebe yumupira wumupira yashyizwe kuruhande rwintebe yumubiri wa valve mugihe cyo gufunga.Ibice byimuka bigereranijwe bikozwe mubikoresho byo kwisiga hamwe na coefficient ntoya cyane yo guterana, bityo torque ikora ni nto.Byongeye kandi, gufunga igihe kirekire amavuta yo gufunga bituma imikorere ihinduka.Mubisanzwe bikoreshwa muburyo bubiri bwo guhindura, ibintu biranga ni gufungura byihuse.Iyo umupira wo mu bwoko bwa O ufunguye byuzuye, impande zombi ntizibujijwe, zikora umuyoboro ugororotse, hamwe no gufunga inzira ebyiri, bikwiranye nigihe cyo guhagarikwa imyanya ibiri cyane cyane itangazamakuru ryanduye kandi rifite fibrous.Umupira wumupira uhora utanga ubushyamirane hamwe na valve mugihe cyo gufungura no gufunga valve.Muri icyo gihe, gufunga hagati ya valve na intebe ya valve bigerwaho nimbaraga zo gufunga pee imbaraga zo gufunga intebe ya valve kuruhande rwumupira, ariko kubera intebe yoroheje yo gufunga icyuma, Imiterere yubukanishi nubumubiri ikora neza. Ikidodo.

V-umupira wumupira

Umupira wumupira wubwoko bwa V ubwoko bwumupira ufite imiterere ya V.Intanga ya valve nigice cya 1/4 cyikigina hamwe na V.Ifite ubushobozi bunini bwo gutembera, intera nini ishobora guhinduka, gukata imbaraga, no gufunga cyane.Ibikoresho bifite imiterere ya fibrous.Muri rusange, imipira yo mu bwoko bwa V ni imipira imwe ifunze.Ntibikwiye gukoreshwa muburyo bubiri.

Impande ya V, guca umwanda.Mugihe cyo kuzunguruka kumupira, icyuma cya V kimeze nkicyuma cyumupira gihuza intebe ya valve, bityo ugaca fibre nibintu bikomeye mumazi, mugihe umupira rusange wumupira udafite iyi mikorere, kuburyo byoroshye gutera umwanda wa fibre gukomera mugihe ufunze, bikenewe mukubungabunga no gusana.Kubungabunga bizana ikibazo gikomeye.Ikirangantego cyumupira wubwoko bwa V ntikizagumishwa na fibre.Mubyongeyeho, kubera gukoresha flange ihuza, biroroshye gusenya no guteranya, nta bikoresho byihariye bisabwa, kandi kubungabunga nabyo biroroshye.iyo valve ifunze.Hariho imikasi imeze nk'umugozi hagati ya V-shusho ya V n'intebe ya valve, idafite ibikorwa byo kwisukura gusa ahubwo inabuza umupira gukomera.Isoko yumuti rero, torque ikora ni nto kandi ihamye cyane.

V-shusho yumupira wa valve nuburyo bwiburyo bwo kuzenguruka, bushobora kumenya kugenzura imigendekere.Irashobora kugera ku ntera zitandukanye zingana ukurikije inguni ya V ifite umupira wa V.Imipira ya V ifite imipira isanzwe ikoreshwa ifatanije na valve ikora hamwe na posisiyo kugirango bigerweho.V-shusho ya valve yibanze irakwiriye cyane mubihe bitandukanye byo guhinduranya, hamwe na coefficient nini yagabanijwe, igipimo kinini gishobora guhinduka, ingaruka nziza yo gufunga, imikorere ya zeru-yoroheje yo guhindura, ingano nto, kandi irashobora gushyirwaho mu buryo buhagaritse.Birakwiye kugenzura gaze, amavuta, amazi nibindi bitangazamakuru.Ubwoko bwa V-umupira wumupira ni iburyo-buringaniye buringaniye, bugizwe numubiri wa V wo mu bwoko bwa valve, pneumatic actuator, posisiyo hamwe nibindi bikoresho;ifite imigendekere yimiterere iranga hafi ijanisha;ifata ibyiciro bibiri-byubatswe, hamwe na tike yo gutangira itara kandi ikora neza.Sensitivity and induction umuvuduko, ubushobozi bwo gukata cyane.
