Imikorere ya Gasket ya Valve n'Ubuyobozi bw'Imikoreshereze

Gaskets za valve zagenewe gukumira amazi ava mu mazi aterwa n'igitutu, ingese, no kwaguka/gufungana kw'ubushyuhe hagati y'ibice. Mu gihe hafi ya byose bifatanyeguhuza's Valive zikenera gasket, ikoreshwa ryazo ryihariye n'akamaro kazo biratandukanye bitewe n'ubwoko bwa valive n'imiterere yayo. Muri iki gice,TWSizasobanura aho balve ishyirwa n'uburyo ibikoresho bya gasket bitoranywa.

I. Ikoreshwa ry'ibanze rya gaskets ni ku gice cy'urukiramende cy'aho valve ihurira.

Valve ikoreshwa cyane

1. Valve y'irembo
2. Valve y'Isi
3. Valve y'ikinyugunyugu(cyane cyane valve y'ibinyugunyugu ifite imiterere ibiri kandi idafite imiterere)
4. Valve yo kugenzura

Muri izi vali, gasket ntikoreshwa mu kugenzura umuvuduko w'amazi cyangwa gufunga muri vali ubwayo, ahubwo ishyirwa hagati y'udupira tubiri (hagati y'udupira twa vali ubwayo n'udupira tw'umuyoboro). Mu gukaza boliti, imbaraga zihagije zo gufunga ziraboneka kugira ngo habeho agafunga kadahinduka, birinda ko umwuka usohoka mu gice gihuza. Inshingano yayo ni ukuzuza icyuho gito kiri hagati y'ubuso bubiri bw'udupira tw'icyuma, bigatuma habaho gufunga 100% ku gice gihuza.

II.Gukoresha Gasket muri Valve "Igipfukisho cya Valve"

Valve nyinshi zikozwe zifite ibice bitandukanye by'valve n'ibipfundikizo kugira ngo byoroshye kubungabunga imbere (urugero, gusimbuza intebe z'valve, valves za disiki, cyangwa gukuraho imyanda), hanyuma zigahambirwa hamwe. Hakenewe kandi gasket kuri iyi miyoboro kugira ngo habeho gufunga neza.

1. Guhuza igipfukisho cya valve n'umubiri wa valve y'irembo na valve y'isi bisaba gukoresha gasket cyangwa impeta ya O.
2. Agakoresho gafite aho gaherereye kandi gakora nk'agakingirizo kadahinduka kugira ngo karinde ko umwuka uva mu gice cy'umubiri w'agakingirizo ujya mu kirere.

III. Gasket yihariye ku bwoko bwihariye bwa valve

Amwe mu mavali akoresha gasket nk'igice cy'ihuriro ryayo ryo gufunga, ryagenewe gushyirwa mu miterere y'amavali.

1. Valve y'ikinyugunyugu-agasanduku k'intebe gafite vali

• Intebe y'agapira k'ibinyugunyugu mu by'ukuri ni gasket y'impeta, ishyirwa mu rukuta rw'imbere rw'umubiri w'agapira cyangwa igashyirwa hafi y'agapira k'ibinyugunyugu.
• Iyo ikinyugunyugudisikiifunze, ikanda gasket y'intebe ya valve kugira ngo ikore ikimenyetso gihindagurika (nk'uko ikinyugunyugudisikiizenguruka).
• Ibikoresho ubusanzwe ni rabha (urugero: EPDM, NBR, Viton) cyangwa PTFE, byagenewe kwakira imiterere itandukanye y'ubushyuhe n'ibindi bipimo bitandukanye.

2. Valve y'umupira-Gasket y'intebe ya Valve

• Intebe y'agatebo k'umupira nayo ni ubwoko bwa gasket, ubusanzwe ikorwa mu bikoresho nka PTFE (polytetrafluoroethylene), PEEK (polyetheretherketone), cyangwa pulasitiki ikozwe mu buryo bw'imbaraga.
• Itanga agapfundikizo hagati y'umupira n'umubiri wa valve, ikaba ikora nk'agapfundikizo kadahinduka (ugereranije n'umubiri wa valve) ndetse n'agapfundikizo gahinduka (ugereranije n'umupira uzenguruka).

IV. Ni izihe valves zisanzwe zidakoreshwa hamwe na gaskets?

1. Vali zometseho: Igice cy'imvange gihuzwa neza n'umuyoboro, bigatuma hadakenerwa flanges na gaskets.
2. Valve zifite imigozi: Ubusanzwe zikoresha imigozi ifunga (nk'ikaseti y'ibikoresho fatizo cyangwa selant), muri rusange bikuraho gukenera gaskets.
3. Valve imwe n'imwe ihendutse cyangwa valve zihariye zifite agace k'uruhande rw'uruhande ka valve kadashobora gusenywa, bityo katagira gasket yo gupfuka uruvange.
4. Valves zifite impeta za O cyangwa gasket zipfunyitse mu byuma: Mu bikorwa bifite umuvuduko mwinshi, ubushyuhe bwinshi, cyangwa byihariye, ibisubizo bigezweho byo gufunga bishobora gusimbura gasket zisanzwe zitari iz'icyuma.

V. Incamake:

Gasket ya valve ni ubwoko bw'ikintu gisanzwe cyo gufunga urufunguzo, gikoreshwa cyane mu guhuza imiyoboro y'amavali atandukanye ya flange, kandi gikoreshwa no mu gufunga amavali menshi. Mu guhitamo, ni ngombwa guhitamo ibikoresho bya gasket bikwiye n'imiterere yabyo hakurikijwe ubwoko bwa valve, uburyo bwo guhuza, ubushyuhe, ubushyuhe n'umuvuduko.
