Ni gute valve z'ibinyugunyugu bikora?

Valve y'ikinyugunyuguni ubwoko bwa valve ikoresha igice cyo gufungura no gufunga disiki kugira ngo isubizeho dogere 90 kugira ngo ifungure, ifunge cyangwa ihindure umuvuduko w'amazi. Valve y'ibinyugunyugu ntabwo ifite imiterere yoroshye gusa, ingano nto, uburemere bworoshye, ikoreshwa ry'ibikoresho bike, ingano nto yo kuyishyiraho, imbaraga nto zo kuyitwara, imikorere yoroshye kandi yihuse, ahubwo inafite imikorere myiza yo kugenzura imikorere no gufunga, kandi ni imwe mu bwoko bwa valve zikurura vuba mu myaka icumi ishize. Valve z'ibinyugunyugu zikoreshwa cyane. Ubwoko n'ingano y'ikoreshwa ryazo bikomeje kwaguka, no gukura kugeza ku bushyuhe bwinshi, umuvuduko mwinshi, umurambararo munini, gukomera cyane, kuramba, imiterere myiza yo kugenzura, n'imikorere myinshi ya valve imwe. Kwizerwa kwayo n'ibindi bimenyetso by'imikorere byageze ku rwego rwo hejuru.

Hamwe no gukoresha umupira w'ubukorano urwanya imiti kugira ngovalve z'ibinyugunyugu, imikorere yavalve z'ibinyugunyugubyanozwa. Kubera ko rubber ikoze mu buryo bwa sintetike ifite imiterere yo kurwanya ingese, kurwanya isuri, kudahindagurika mu buryo bungana, kwihanganira neza, gukora byoroshye, bihendutse, nibindi, rubber ikoze mu buryo bwa sintetike ifite imiterere itandukanye ishobora gutoranywa hakurikijwe ibisabwa bitandukanye kugira ngo yuzuze imiterere y'akazi kayo.valve z'ibinyugunyugu.

Kubera ko polytetrafluoroethylene (PTFE) ifite ubushobozi bwo kurwanya ingese, imikorere yayo ihamye, ntiyoroshye gusaza, ifite ubushobozi buke bwo gukururana, yoroshye kuyirema, ifite ubushobozi bwo kudahinduka, kandi ishobora kunoza imiterere yayo yose binyuze mu kuzuza no kongeramo ibikoresho bikwiye, ibikoresho byo gufunga valve y'ikinyugunyugu bifite imbaraga nziza kandi bifite ubushobozi buke bwo gukururana bishobora kuboneka, kandi imbogamizi za rubber y'ubukorikori zirakemuka, bityo ibikoresho bya polymer polymeric bihagarariwe na PTFE n'ibikoresho byayo byahinduwe byo kuzuza byakoreshejwe cyane muri valve y'ikinyugunyugu, ku buryo imikorere ya valve y'ikinyugunyugu yarushijeho kunozwa.Utuzu tw'ikinyugunyuguHakozwe ubushyuhe n'umuvuduko mwinshi, hakozwe imikorere myiza yo gufunga no kumara igihe kirekire.

Kugira ngo huzuzwe ibisabwa mu nganda nko mu bushyuhe buri hejuru n’ubuke, isuri ikomeye, no kuramba, vali z’ibinyugunyugu zifunga icyuma zatejwe imbere cyane. Hamwe no gukoresha ubushyuhe bwinshi, ubushyuhe buke, ubukonje bukomeye, ubukonje bukomeye, n’ibikoresho bikomeye bya aloyi mu vali z’ibinyugunyugu, vali z’ibinyugunyugu zifunga icyuma zakoreshejwe cyane mu nganda nko mu bushyuhe buri hejuru n’ubuke, isuri ikomeye, no kuramba, kandi vali z’ibinyugunyugu zifite umurambararo munini (9 ~ 750mm), umuvuduko mwinshi (42.0MPa) n’ubushyuhe bwinshi (-196 ~ 606°C) zaragaragaye, ku buryo ikoranabuhanga rya vali z’ibinyugunyugu ryageze ku rwego rushya.

Iyo valve y'ikinyugunyugu ifunguye neza, igira ubushobozi buke bwo kudatera amazi. Iyo umwobo uri hagati ya 15° ~ 70°, ishobora gukoreshwa mu kugenzura amazi anyuramo, bityo ikoreshwa rya valve y'ikinyugunyugu rikunze gukoreshwa cyane mu bijyanye no guhindura uburebure bw'umurambararo munini.

Bitewe n'uko isahani y'ikinyugunyugu cy'ikinyugunyugu ishobora guhanagurwa, imvange nyinshi z'ikinyugunyugu zishobora gukoreshwa mu byuma bifite ibintu bikomeye bimanitse. Bitewe n'imbaraga z'ikinyugunyugu, gishobora no gukoreshwa mu byuma bivanze n'ifu.

Valve z'ibinyugunyugu zikwiriye kugenzura amazi. Kubera ko igitutu cya valve y'ibinyugunyugu mu muyoboro ari kinini, kikubye inshuro eshatu ugereranyije n'igitutu cy'irembo, mu gihe cyo guhitamo valve y'ibinyugunyugu, ingaruka z'igitutu cya sisitemu y'imiyoboro zigomba kwitabwaho byuzuye, kandi imbaraga z'ikinyugunyugu zo kwihanganira igitutu cy'imiyoboro iyo gifunze nazo zigomba kwitabwaho. Byongeye kandi, imbogamizi z'ubushyuhe bw'imikorere y'ibikoresho by'intebe bya elastomeric zishobora gukorerwaho ku bushyuhe bwinshi nazo zigomba kwitabwaho.

Valve y'ikinyugunyugu ifite uburebure buto bw'inyubako n'uburebure rusange, umuvuduko wo gufungura no gufunga vuba, hamwe n'imiterere myiza yo kugenzura amazi. Ihame ry'imiterere y'avalve y'ikinyugunyugu ni ryo rikwiriye cyane mu gukora valve nini. Iyo valve y'ikinyugunyugu ikenewe gukoreshwa mu kugenzura umuvuduko w'amazi, ni ngombwa guhitamo ingano n'ubwoko nyabwo bw'avalve y'ikinyugunyugu kugira ngo ibashe gukora neza kandi neza.

Muri rusange, mu gufunga, kugenzura amabwiriza n'uburyo bwo gufunga, uburebure bw'inyubako ni bugufi, umuvuduko wo gufungura no gufunga ni wihuta, kandi hakenewe gukata umuvuduko muke (itandukaniro rito ry'umuvuduko), kandi ni byiza gukoresha valve y'ikinyugunyugu. Valve z'ikinyugunyugu zishobora gukoreshwa iyo hari uburyo bwo guhindura imyanya ibiri, umuyoboro wagabanutseho umurambararo, urusaku ruto, gusohora amazi no guhumeka, amazi make mu kirere, n'ibikoresho byo gufunga. Mu bihe bidasanzwe byo gukora, guhindura uburyo bwo gufunga, cyangwa gufunga neza, kwangirika gukomeye, ubushyuhe buke (cryogenic) n'ibindi bikorwa.
