Ni izihe nyungu n'ibibi byavalve y'isi?
Igice cyo gufungura no gufunga cya valve yo gufunga gifite ishusho nini isa n'aho ifunga, kandi ubuso bwo gufunga ni burambitse cyangwa buto, kandi bugenda ku murongo wo hagati w'amazi. Uburyo bwo kugenda bw'inkoni bufite ubwoko bw'inkoni yo guterura (igitereko cya valve kirazamuwe kandi kigamanurwa, uruziga rw'intoki ntiruzamuka), kandi hariho ubwoko bw'inkoni yo guterura izenguruka (uruziga rw'intoki n'uruziga rw'inkoni bizenguruka kandi bigazamuka hamwe, kandi nut iba iri ku mubiri wa valve). Valve yo guhagarara ikwiriye gusa iyo ifunguye kandi ifunze neza, kuyihindura no kuyigonga ntibyemewe.
Valve yo guhagarika ni valve ifunga ku ngufu, bityo iyo valve ifunze, umuvuduko ugomba gushyirwa ku gipfundikizo kugira ngo ihatire ubuso bwo gufunga ntibuve. Iyo icyuma cyinjiye muri valve itandatu uhereye munsi ya disiki ya valve, imbaraga zikoreshwa zigomba gutsinda ni imbaraga zo gukururana kw'umuzingo wa valve n'aho ipakira hamwe n'imbaraga ziterwa n'umuvuduko w'icyuma. Imbaraga zo gufunga valve ziruta imbaraga zo gufungura valve, bityo valve. Umurambararo w'inkoni ugomba kuba munini, bitabaye ibyo umuyoboro wo gufunga icyuma cya valve uzananirwa. Mu myaka ya vuba aha, kuva aho valve zifunga ubwayo zigaragaye, icyerekezo cy'umuvuduko wo hagati wa valve yazimye cyarahindutse uhereye hejuru y'aho valve ihurira ugana mu mwobo wa valve. Muri iki gihe, munsi y'umuvuduko wo hagati, imbaraga zo gufunga valve ni nto, mu gihe imbaraga zo gufungura valve ari nini. Umurambararo ushobora kugabanuka uko bikwiye. Muri icyo gihe, munsi y'umuvuduko wo hagati, ubu bwoko bwa valve nabwo burushaho gukomera. Valve yo mu gihugu cyanjye "Sanhua" yigeze kuvuga ko icyerekezo cy'umuvuduko wa valve yo guhagarika kigomba kuba kuva hejuru kugeza hasi.
Iyo valve yo gufunga ifunguye, iyo uburebure bw'ifungura rya disiki ari 25%-30% by'umurambararo w'amazina, amazi aba ageze ku rugero ntarengwa, bigaragaza ko valve igeze ku mwanya wayo wo gufunga. Kubwibyo, umwanya wo gufunga wa valve ugomba kugenwa n'uburyo disiki ya valve ifunga ikora.
Valve yo guhagarara ishobora kugabanywamo: valve yo guhagarara, valve yo hejuru y'umugozi wo guhagarara, valve yo hasi y'umugozi wo guhagarara, valve yo guhagarara igororotse, valve yo guhagarara y'inguni, valve yo guhagarara y'inzira eshatu, valve yo guhagarara y'umuyoboro w'amazi utaziguye, valve yo guhagarara ya plunger, valve yo guhagarara ifite ishusho ya needle.
Ibyiza: imiterere yoroshye, gukora no kubungabunga byoroshye.
Uburyo bwo gukora ni buto, kandi igihe cyo gufungura no gufunga ni gito.
Imikorere myiza yo gufunga, gukururana guke hagati y'ubuso bwo gufunga, no kuramba.
Ibibi:
Ubudahangarwa bw'amazi ni bwinshi, kandi imbaraga zisabwa kugira ngo umuntu afungure kandi afunge ni nyinshi.
Ntabwo bikwiriye gukoreshwa mu bintu bifite uduce duto, ubushyuhe bwinshi kandi byoroshye guteka.
Imikorere mibi yo gukosora
Amabwiriza yo gushyiraho no kubungabunga: Valve yo guhagarara ikoreshwa n'uruziga rw'intoki n'umukingo ishobora gushyirwa aho ari ho hose h'umuyoboro.
Amapine y'intoki, imigozi n'uburyo bwo guhinduranya imbaraga ntibyemewe gukoreshwa mu guterura. Icyerekezo cy'amazi kigomba kuba gihuye n'icyerekezo cy'umwambi ugaragara ku gice cy'ingufu.
