EN545 Standard: Ingano y'umuyoboro w'icyuma ukozwe mu cyuma gishyushye n'umuyoboro wa Spigot n'umuyoboro w'icyuma gishyushye

1. Ihuriro ry'icyuma gihindagurika gihindagurika

Ubwoko bw'ingingo bukunze kugaragara cyane kuriumuyoboro w'icyuma ukozwe mu cyuma, agace ka T gashingiye ku gitutu kiri hagati y'impeta ya rubber n'agace kayo na spigot (bikomoka ku gice cyo gukandagira mbere yo gushyirwaho) kugira ngo gakore agafunga gashobora guterwa n'amazi. Imiterere y'agace kayo ishingira ku buryo impeta ya rubber ihagaze n'inguni yo guhindukira, bigatuma ihinduka ku mizingo imwe n'imwe kandi igatanga urwego runaka rwo kudahindagurika. Gafite imiterere yoroshye, koroshye gushyiraho, kandi gafite imiterere myiza yo gufunga. Ariko, ikibazo cyako ni ubushobozi buke bwo gukumira imiyoboro igwa, kuko agace kayo kadashobora kwihanganira imbaraga z'imirongo. Kubwibyo, insinga zo gushyigikira zirakenewe ku miyoboro igonga kugira ngo gashobore kurwanya imbaraga z'imirongo.

Imiyoboro y'ingofero ifite ishusho ya T ikoreshwa cyane mu miyoboro y'icyuma ikoze mu buryo bwa ductile. Yoroshye kuyishyiraho, ihendutse, kandi yemerera inguni nto zo kuyihindura. Gushyiraho biroroshye: shyiramo spigot mu gikoresho, maze agafunga ka rubber gahita gafunga. Ibi byihutisha cyane kuyishyiraho ariko bigagabanya ibisabwa mu bikoresho no mu buhanga bw'abakozi. Ishusho ikurikira ni ishusho y'igice cy'ingofero y'icyuma ikozwe mu buryo bwa ductile n'aho ishyirwa:

• DE ni umurambararo w'inyuma w'umuyoboro w'icyuma ukozwe mu buryo bwa ductile. d1 ni umurambararo w'inyuma w'umuyoboro w'icyuma ukozwe mu buryo bwa ductile.
• d2 ni umurambararo w'imbere w'umuyoboro w'impeta ya rubber mu mwobo w'icyuma ukoresha ductile.
• d3 ni umurambararo w'imbere w'umuyoboro w'icyuma ukoresha ductile.
• d5 ni umurambararo w'imbere w'umuyoboro w'icyuma ukozwe mu cyuma gifunganye n'impeta y'icyuma ikoreshwa mu gufunga.
• d6 ni umurambararo w'imbere w'umuyoboro w'icyuma upfundikiye uri ku mpera y'umuyoboro.

Mu gihe cyo gushushanya no gukora, impera y'isoko d3 igomba kuba nini gato kuruta umurambararo w'inyuma wa spigot DE kugira ngo habeho icyuho gikwiye cyo kuyishyiraho. Umurambararo w'imbere d2 na d3 ugomba kuba uri mu rugero rwo kwihanganira. Impeta za rubber kuri soketi na spigot zubatswe mu buryo bw'uruvange rw'uruvange rukomeye n'urworoshye. Igice cya rubber gikomeye gitanga inkunga ikenewe n'inkingi hagati y'aho umuyoboro uhurira, bikerekana ko impeta ya rubber ifunze neza kugira ngo habeho umutwaro wa 1-5 MPa mbere, bikarinda amazi gusohoka mu muyoboro. Uko umuvuduko w'amazi mu muyoboro wiyongera, impeta ya rubber irushaho kwangirika, yongera umuvuduko w'aho umuyoboro uhurira ukagera kuri 15-25 MPa, bigatuma umuvuduko wongera kandi ugakomera ku buryo bwo gufunga umuyoboro.

2. Umuyoboro w'icyuma wa DuctileUburebure

Uburebure busanzwe bw'umuyoboro w'icyuma ukoreshwa mu buryo bwa ductile ukurikije igipimo cya EN545 ni metero 6, ibipimo bisanzwe byemejwe n'inganda nyinshi haba mu gihugu no mu mahanga. Kugira ngo byorohereze ubwikorezi bw'amakontenari, imiyoboro ikorerwa mu Bushinwa isanzwe ifite uburebure bwa metero 5.6 cyangwa 5.7, nk'uko byemejwe n'abatanga ibicuruzwa n'abaguzi. Imiyoboro ikorerwa mu Buhinde isanzwe ifite uburebure bwa metero 5.5.
