Mu bakoresha bakoresha umubyimba munini wa diameter nini ya buri munsi, bakunze kuvuga ikibazo cyuko umubumbe munini wa diameter nini cyane bigoye gufunga iyo bikoreshejwe mubitangazamakuru bifite itandukaniro rinini cyane ryumuvuduko, nk'amazi, umuvuduko mwinshi amazi, nibindi. Iyo bifunze nimbaraga, burigihe usanga hazabaho kumeneka, kandi biragoye gufunga cyane. Impamvu yiki kibazo iterwa nigishushanyo mbonera cya valve hamwe numuriro udahagije wurwego rwumuntu.

Isesengura ryingorabahizi muguhindura ibipimo binini bya diameter

Impuzandengo y'abakuze itambukiranya imipaka isohoka ni 60-90kg, bitewe na physique zitandukanye.

Mubisanzwe, icyerekezo cyerekezo cyisi ya valve cyashizweho kugirango kibe gito kandi hejuru. Iyo umuntu afunze valve, umubiri wumuntu usunika intoki kugirango uzunguruke mu buryo butambitse, kuburyo flap ya valve igenda hepfo kugirango ibone gufunga. Muri iki gihe, birakenewe gutsinda guhuza imbaraga eshatu, arizo:

(1) Imbaraga zitera Axial Fa;

(2) Imbaraga zo guteranya Fb hagati yo gupakira nigiti cya valve;

;

Igiteranyo cyibihe ni ∑M = (Fa + Fb + Fc) R.

Birashobora kugaragara ko uko diameter nini, niko imbaraga zo gutera axial nini. Iyo yegereye leta ifunze, imbaraga zo gusunika hafi ya hafi yumuvuduko nyawo wumuyoboro (kubera P1-P2≈P1, P2 = 0)

Kurugero, indege ya DN200 ya Calibre ikoreshwa kumiyoboro ya 10bar, gusa icyambere cyo gufunga axial Fa = 10 × πr2 = 3140kg, kandi imbaraga zumuzingi utambitse zisabwa kugirango zifunge zegereye imbaraga zuzenguruka zitambitse umubiri usanzwe ushobora gukora Ibisohoka. imbaraga ntarengwa, biragoye cyane rero kumuntu umwe gufunga byimazeyo valve muriyi miterere.

Birumvikana ko inganda zimwe zisaba gushyiramo iyo valve muburyo butandukanye, ikemura ikibazo cyo kugorana kuyifunga, ariko hariho n'ikibazo ko kuyifungura bigoye kuyifunga.

Isesengura ryibitera kumeneka imbere kwimbere ya Diameter nini ya Globe

Umubumbe munini wa diametre wisi ukoreshwa mubisumizi, silinderi nkuru, imiyoboro ya parike nahandi. Ibi bibanza bifite ibibazo bikurikira:
. Byongeye kandi, gutwika neza kumashanyarazi ntibishobora kuba 100%, bizatera umwuka kumasoko ya boiler kugira amazi menshi, ibyo bikaba byoroshye gutera cavitation na cavitation kwangirika hejuru ya kashe ya valve.

. ntabwo ari byiza cyane, igice cyamazi gikunze kugwa. Ibintu bya acide na alkali bizatera kwangirika no gutwarwa hejuru yikimenyetso; ibintu bimwe na bimwe bishobora gutondekwa bishobora kandi kwizirika hejuru yikidodo cya valve hanyuma kigahinduka, bigatuma valve idashobora gufunga neza.

. Tera isuri, cavitation nibindi byangiritse hejuru yikimenyetso cya valve.

. mbere yo guhagarara valve irashobora gufungurwa byuzuye kugirango wirinde kwangiza imiyoboro. Ubushyuhe bwihuse butera kwaguka gukabije, byangiza ibice bimwe bihuza. Nyamara, muriki gikorwa, gufungura valve akenshi usanga ari bito cyane, bigatuma igipimo cy’isuri kiba kinini cyane kuruta ingaruka zisanzwe zikoreshwa, kandi kigabanya cyane ubuzima bwumurimo wububiko bwa kashe.
