API 602 Umuyoboro w'isi

NSW API 602 yisi yose, gufungura no gufunga igice cyicyuma cyamahimbano ya valve ya bolt bonnet ni irembo. Icyerekezo cyerekezo cy irembo ni perpendicular yerekeza kumazi. Irembo ryibyuma byahimbwe birashobora gukingurwa no gufungwa gusa, kandi ntibishobora guhinduka no guterurwa. Irembo ryibyuma byahimbwe ibyuma bifite ibyuma bibiri bifunze. Ibice bibiri bifunga kashe yuburyo busanzwe bwinjiriro bwa valve bugira ishusho ya wedge, kandi impande ya wedge iratandukanye nibipimo bya valve. Uburyo bwo gutwara ibinyabiziga byahimbwe ibyuma ni: intoki, pneumatike, amashanyarazi, gazi-amazi.

Ubuso bwa kashe ya rugi yibyuma birashobora gufungwa gusa nigitutu giciriritse, ni ukuvuga, igitutu giciriritse gikoreshwa mugukanda hejuru yikimenyetso cyumuryango kugeza kuntebe ya valve kurundi ruhande kugirango hamenyekane ubuso bwa kashe, aribwo kwishyiriraho ikimenyetso. Ibyinshi mumarembo ahatirwa gufunga, ni ukuvuga, mugihe iyo valve ifunze, birakenewe guhatira icyapa cy irembo kuntebe yintebe nimbaraga zo hanze kugirango harebwe kashe yubuso.

Irembo ry'irembo ry'irembo rigenda neza hamwe n'uruti rwa valve, ibyo bita lift ya rugi ya rugi (nanone bita inkoni ifunguye). Mubisanzwe hariho umugozi wa trapezoidal kurinkoni yo guterura. Ibinyomoro byimuka biva hejuru ya valve hamwe nuyobora umurongo ku mubiri wa valve kugirango uhindure icyerekezo kizenguruka umurongo, ni ukuvuga urumuri rukora mumikorere.
