Irembo Agaciro VS Umupira

1. Ihame:

Umupira wumupira: Gufungura no gufunga igice cyumupira wumupira ni umuzingi, kandi intego yo gufungura no gufunga igerwaho no kuzunguruka umuzenguruko 90 ° uzengurutse umurongo wikibaho.Umupira wumupira ukoreshwa cyane cyane mugukata, gukwirakwiza no guhindura icyerekezo cyogutwara imiyoboro.Umupira wumupira wateguwe hamwe na V ifungura nawo ufite imikorere myiza yo guhindura ibintu.

Irembo rya Valve: gufunga umunyamuryango (Wedge) bigenda byerekeza ku cyerekezo cyerekezo cyumuyoboro wa axe gikoreshwa cyane cyane mugukata imiyoboro kumuyoboro, ni ukuvuga gufungura cyangwa gufunga byuzuye.Muri rusange, amarembo y amarembo ntashobora gukoreshwa mugutunganya imigendekere.Irashobora gukoreshwa mubushyuhe buke cyangwa ubushyuhe bwinshi hamwe numuvuduko mwinshi, kandi irashobora gukoreshwa ukurikije ibikoresho bitandukanye bya valve.

2. Ibyiza n'ibibi

2.1 Ibyiza byumupira wumupira

1) Ifite umuvuduko muke (mubyukuri 0);irashobora gukoreshwa mu buryo bwizewe mu bitangazamakuru byangirika hamwe n’amazi make atetse kuko ntabwo azaguma mugihe cyo gukora (mugihe nta mavuta yo kwisiga);

2), mumuvuduko mwinshi nubushyuhe, birashobora kugera kashe yuzuye;

3) Irashobora gutahura gufungura no gufunga byihuse, kandi igihe cyo gufungura no gufunga inzego zimwe ni 0.05 ~ 0.1s gusa kugirango urebe ko ishobora gukoreshwa muri sisitemu yo gutangiza intebe yikizamini.Iyo valve ifunguye igafungwa vuba, imikorere nta ngaruka igira;

4).Gufunga umuzingi birashobora guhita bihagarikwa kumupaka

5).Iyo ifunguye byuzuye kandi ifunze byuzuye, ubuso bwa kashe yumupira hamwe nintebe ya valve bitandukanijwe hagati, bityo imiyoboro inyura muri valve kumuvuduko mwinshi ntabwo izatera isuri hejuru yikimenyetso;

6).Hamwe nimiterere yoroheje hamwe nuburemere bworoshye, birashobora gufatwa nkuburyo bwiza bwa valve buboneye kubushyuhe buke bwo hagati;

7) Umubiri wa valve uringaniye, cyane cyane imiterere yumubiri wa weld weld, ushobora kwihanganira neza imihangayiko ituruka kumuyoboro;

8) Igice cyo gufunga kirashobora kwihanganira itandukaniro ryumuvuduko mwinshi mugihe cyo gufunga.

9).Umupira wumupira hamwe numubiri wuzuye wa valve urashobora gushyingurwa mubutaka, kugirango imbere ya valve itangirika, kandi ubuzima bwumurimo bushobora kugera kumyaka 30.Nibikoresho byiza bya peteroli na gaze gasanzwe.

2.2 Ibibi byumupira wumupira

Kuberako icyicaro cyingenzi gifunga impeta yumupira wumupira ni polytetrafluoroethylene, yinjizwamo ibintu hafi ya byose bya chimique, kandi ifite ibiranga coefficente ntoya, imikorere ihamye, ntibyoroshye gusaza, ubushyuhe bwagutse nibikorwa byiza byo gufunga.Ibiranga ibintu byose.

Ariko ibintu bifatika bya PTFE, harimo coefficente yo kwaguka, kumva neza imbeho ikonje, hamwe nubushyuhe buke bwumuriro, bisaba ko igishushanyo mbonera cyicyicaro kigomba kubakwa hafi yiyi mitungo.Kubwibyo, iyo ibikoresho byo gufunga bigoye, ubwizerwe bwa kashe bwangiritse.

Byongeye kandi, PTFE ifite igipimo cyo kurwanya ubushyuhe buke kandi irashobora gukoreshwa munsi ya 180 ° C.Hejuru yubushyuhe, ibikoresho bifunga bizagabanuka.Ku bijyanye no gukoresha igihe kirekire, muri rusange ikoreshwa kuri 120 ° C.

2.3 Ibyiza byo kumarembo

1) Kurwanya imigezi ni bito.Umuyoboro uciriritse imbere yumubiri wa valve uragororotse, urwego rutemba kumurongo ugororotse, kandi irwanya umuvuduko ni nto.

2) Nibindi byinshi bizigama umurimo mugihe cyo gufungura no gufunga.Ugereranije na valve yisi, kuko yaba ifunguye cyangwa ifunze, icyerekezo cyo kugenda kw irembo ni perpendicular yerekeza kumurongo ugana hagati.

3) Uburebure ni bunini kandi igihe cyo gufungura no gufunga ni kirekire.Gufungura no gufunga urugi ni binini, kandi guterura no kumanura bikorwa na screw.

4) Amazi yo ku nyundo ntabwo yoroshye kubaho.Impamvu nigihe kirekire cyo gufunga.

5) Ikigereranyo gishobora gutemba mu cyerekezo icyo aricyo cyose kumpande zombi, byoroshye gushiraho.Irembo rya valve umuyoboro uringaniye kumpande zombi.

2.4 Ibibi byo mumarembo

1) Biroroshye gutera isuri no gushushanya hagati yikimenyetso, kandi kubungabunga biragoye.

3) Ibipimo byo hanze ni binini, umwanya runaka urasabwa gukingurwa, kandi igihe cyo gufungura no gufunga ni kirekire.

4) Imiterere iragoye.

Ese imipira yumupira iruta amarembo?

Ibyiza byumupira wumupira hejuru yumuryango ni uko bafunga cyane, bityo bakarwanya kumeneka kuruta amarembo.Ibi biterwa nimiterere yabo 100%.Mubyongeyeho, imipira yumupira iroroshye gukoresha kuruta amarembo y amarembo, ifite ibipimo byo kunanirwa, kandi biramba.

Ibiranga imipira yumupira ituma biba byiza muguhagarika amazi yo kugenzura.

Imipira yumupira idahwema gukora neza nyuma yizunguruka nyinshi kandi zizewe kandi zirashobora gufunga umutekano nubwo nyuma yigihe kinini cyo kudakora.Kubera izo mpamvu, imipira yumupira ikunzwe kuruta irembo nisi yisi.

Ariko munsi yumuvuduko nubunini bumwe, umupira wumupira uhenze kuruta irembo.
