Ibyiza byo guhagarika valve

Gufungura no gufunga ibice byahagaritswe ni disiki imeze nka plaque, hejuru yikidodo kiringaniye cyangwa kirahuzagurika, kandi disiki igenda mumurongo ugororotse kumurongo wo hagati wamazi. Imiterere yimikorere yinkoni ya valve ikubiyemo ubwoko bwinkoni yo guterura (inkoni ya valve iraterurwa kandi intoki ntizaterurwa) hamwe nubwoko bwikizunguruka buzunguruka (intoki zizunguruka zikazamurwa hamwe ninkoni ya valve, hanyuma umutobe ugashyirwaho umubiri wa valve). Imikorere yo guhagarika valve irakoreshwa gusa kumugaragaro wuzuye no gufunga byuzuye, kandi ntabwo byemewe kugenzura no gutereta. Ibi bigenwa cyane cyane nibiranga valve ihagarara, nkibi bikurikira:

Ibyiza bigaragara cyane ni:

Muburyo bwo gufungura no gufunga, imbaraga zo guterana hagati ya disiki nubuso bwa kashe yumubiri wa valve ni ntoya kuruta iy'irembo, bityo irashobora kwambarwa.

Mubisanzwe, uburebure bwo gufungura ni 1/4 gusa cyumuyoboro wintebe ya valve, bityo rero ni nto cyane kurenza irembo.

Mubisanzwe, hari ubuso bumwe gusa bwo gufunga kumubiri wa valve na disiki, kuburyo inzira yo gukora ari nziza kandi yoroshye kubungabunga.

Imikorere yo guhagarara valve ahanini ni ugukata imiyoboro mumiyoboro. Ugereranije na valve ya gate, ifite uburyo bwiza bwo kugenzura imikorere, uburebure buke bwo gufungura, igihe gito cyo gufunga, gukora neza no kuyitaho, kandi ubuso bwayo bwo gufunga ntabwo byoroshye kwambara no gushushanya, hamwe nibikorwa byiza byo gufunga hamwe nubuzima bwa serivisi ndende; imiterere yumubiri wa valve igishushanyo cya stop valve ni zigzag, nuko ifite imbaraga nyinshi zo kurwanya no gukoresha ingufu nyinshi; irakwiriye kubiciriritse nkibicuruzwa byamavuta namavuta, kandi ntibikwiriye kubiciriritse hamwe nubwiza bunini, ibice, kokiya nubushyuhe. Ikigereranyo. Hagati hamwe n'umuvuduko mwinshi uhagarika indangagaciro na diameter nini yo guhagarara irashobora kuba imiterere iringaniye. Umuyoboro wa Throttle, kwagura ibicuruzwa byahagaritswe na valve, bigenzura umuvuduko nigitemba giciriritse muguhindura igice cyambukiranya inzira. Usibye ko gufungura no gufunga ibice byuburyo bwa cone imiterere, ibyinshi muribyo bisa na valve ihagarara.

Iyo umubumbe wa globe wafunguwe, mugihe uburebure bwa disiki ari 25% -30% ya diameter nominal, umuvuduko wogushika ugera kuri byinshi, byerekana ko valve yageze kumwanya wuzuye. Kubwibyo, imyanya yuzuye ifunguye ya valve ihagarikwa kugenwa na stroke ya disiki.
