1 points Ingingo z'ingenzi zo guhitamo valve

A. Kugaragaza intego ya valve mubikoresho cyangwa igikoresho

Menya imiterere yakazi ya valve: imiterere yikigereranyo gikoreshwa, umuvuduko wakazi, ubushyuhe bwakazi, imikorere nibindi.

B. Hitamo neza ubwoko bwa valve

Guhitamo neza kwubwoko bwa valve bishingiye kubishushanyo mbonera byuzuye mubikorwa byose byakozwe. Mugihe uhisemo ubwoko bwa valve, uwashizeho agomba kubanza kumenya imiterere yimiterere nimikorere ya buri valve.

C. Emeza ko iherezo ryanyuma rya valve

Muguhuza urudodo, guhuza flange no gusudira kurangiza, kandi bibiri byambere bikoreshwa cyane. Indangantego zometseho ni indangagaciro zifite diameter iri munsi ya 50mm. Niba diameter ari nini cyane, biragoye cyane gushiraho no gufunga igice gihuza. Kwishyiriraho no gusenya flange ihujwe na valve biroroshye cyane, ariko ni binini kandi bihenze kuruta indodo zometseho, bityo rero birakwiriye guhuza imiyoboro yubunini butandukanye hamwe nigitutu. Guhuza gusudira birakoreshwa muburyo bwo kugabanya imizigo, byizewe kuruta guhuza flange. Nubwo bimeze bityo ariko, biragoye gusenya no kongera gushyiramo valve yasuditswe, bityo imikoreshereze yayo igarukira gusa aho ishobora kuba isanzwe ikora neza igihe kirekire, cyangwa aho serivisi zanditswe kandi ubushyuhe buri hejuru.

D. Guhitamo ibikoresho bya valve

Hitamo ibikoresho by'igikonoshwa, imbere hamwe no gufunga hejuru ya valve. Usibye gusuzuma imiterere yumubiri (ubushyuhe, umuvuduko) hamwe nubumara bwa chimique (korosivite) yuburyo bukora, isuku yikigereranyo (niba hari ibice bikomeye) nayo igomba gutozwa. Mubyongeyeho, reba ingingo zijyanye na leta nishami ryabakoresha. Guhitamo neza kandi gushyira mu gaciro ibikoresho bya valve birashobora kubona ubuzima bwa serivise yubukungu nubuzima bwiza bwa serivise nziza. Urutonde rwo gutoranya ibintu byumubiri wa valve ni icyuma cyitwa nodular - ibyuma bya karubone - ibyuma bitagira umwanda, kandi uburyo bwo gutoranya ibikoresho byerekana impeta ni reberi - Umuringa - ibyuma bivanze - F4.

2 、 Intangiriro kumibande isanzwe

A. Ikinyugunyugu

Ikinyugunyugu ni uko isahani yikinyugunyugu izenguruka dogere 90 ikikije uruziga ruhamye mu mubiri wa valve kugirango urangize imirimo yo gufungura no gufunga. Ikinyugunyugu kinyugunyugu gifite ibyiza byubunini buto, uburemere bworoshye nuburyo bworoshye. Igizwe gusa nibice bike.

Kandi kuzunguruka gusa 90 °; Irashobora gukingurwa no gufungwa vuba kandi imikorere iroroshye. Iyo ikinyugunyugu kiba kiri mumwanya wuzuye, ubunini bwisahani yikinyugunyugu nicyo cyonyine kirwanya iyo imiyoboro inyuze mumubiri wa valve. Kubwibyo, igitutu cyumuvuduko cyakozwe binyuze muri valve ni gito cyane, kuburyo gifite imiterere myiza yo kugenzura ibintu. Ikinyugunyugu kigabanyijemo kashe ya elastike yoroshye hamwe nicyuma gikomeye. Kuri kashe ya kashe ya elastike, impeta yo gufunga irashobora gushirwa kumubiri wa valve cyangwa igahuzwa nisahani yikinyugunyugu, hamwe nibikorwa byiza byo gufunga. Ntishobora gukoreshwa gusa mu gutereta gusa, ahubwo irashobora no gukoreshwa kumuyoboro wa vacuum wo hagati hamwe nuburyo bubora. Umuyoboro ufite kashe yicyuma muri rusange ufite igihe kirekire cyumurimo kurenza icyapa cya elastique, ariko biragoye kugera kashe yuzuye. Mubisanzwe bikoreshwa mugihe hamwe nimpinduka nini mugutemba no kugabanuka kwumuvuduko no gukora neza. Ikidodo c'icyuma gishobora guhuza n'ubushyuhe bwo hejuru bwo gukora, mugihe kashe ya elastike ifite inenge igarukira kubushyuhe.

B. Irembo ry'irembo

Irembo ry'irembo ryerekeza kuri valve ifite umubiri wo gufungura no gufunga (plaque ya valve) itwarwa nigiti cya valve hanyuma ikazamuka ikamanuka hejuru yikimenyetso cya kashe yintebe, ishobora guhuza cyangwa guca umuyoboro wamazi. Irembo ry'irembo rifite imikorere myiza yo gufunga kuruta guhagarika valve, kurwanya amazi mato, gufungura-kuzigama imirimo no gufunga, kandi bifite imikorere imwe yo kugenzura. Nimwe mumyanya ikoreshwa cyane yo guhagarika. Ikibi ni uko ubunini ari bunini, imiterere iraruhije kuruta guhagarara, guhagarara hejuru biroroshye kwambara kandi biragoye kuyifata, kandi muri rusange ntibikwiriye guterana. Ukurikije umwanya wurudodo kuruti rwa valve, valve y amarembo irashobora kugabanwa mubwoko bwinkoni bwerekanwe hamwe nubwoko bwinkoni bwihishe. Ukurikije imiterere yimiterere yintama, irashobora kugabanywa mubwoko bwa wedge nubwoko bubangikanye.

C. Reba valve

Kugenzura valve ni valve ishobora guhita irinda gusubira inyuma kwamazi. Disiki ya valve ya cheque ya valve yafunguwe munsi yumuvuduko wamazi, kandi amazi atemba ava muruhande rwinjira yerekeza kuruhande. Iyo umuvuduko uri kumurongo winjira uri munsi kurenza kuruhande rwo gusohoka, disiki ya valve izahita ifunga mugikorwa cyitandukaniro ryumuvuduko wamazi, uburemere bwacyo nibindi bintu kugirango birinde gutemba gutemba. Ukurikije imiterere yuburyo, igabanijwemo guterura cheque valve na swing check valve. Ubwoko bwo guterura bufite imikorere myiza yo gufunga no kurwanya amazi menshi kuruta ubwoko bwa swing. Kubijyanye no guswera umuyoboro wa pompe, pompe yo hepfo igomba guhitamo. Igikorwa cyayo nukuzuza umuyoboro winjira wa pompe amazi mbere yo gutangira pompe; Nyuma yo guhagarika pompe, komeza umuyoboro winjira na pompe umubiri wuzuye amazi kugirango utangire. Ububiko bwo hasi busanzwe bushyirwa gusa kumuyoboro uhagaze kuri pompe yinjira, kandi hagati iva hasi ikagera hejuru.

D. Umupira wumupira

Gufungura no gufunga igice cyumupira wumupira ni umupira ufite umuzenguruko unyuze mu mwobo. Umupira uzunguruka hamwe nigiti cya valve kugirango ufungure kandi ufunge valve. Umupira wumupira ufite ibyiza byuburyo bworoshye, guhinduranya byihuse, gukora byoroshye, ingano ntoya, uburemere bworoshye, ibice bike, kurwanya amazi mato, gufunga neza no kubungabunga neza.

E Umuyoboro w'isi

Umubumbe w'isi ni umuyonga wamanutse, kandi igice cyo gufungura no gufunga (disiki ya valve) gitwarwa nigiti cya valve kugirango kizamuke hejuru no munsi yumurongo wintebe ya valve (hejuru yikimenyetso). Ugereranije na valve valve, ifite imikorere myiza yo kugenzura, imikorere idahwitse, imiterere yoroshye, gukora neza no kuyitaho, kurwanya amazi menshi nigiciro gito. Nibisanzwe bikoreshwa mumashanyarazi, mubisanzwe bikoreshwa mumiyoboro mito na ntoya ya diameter.
