Ikinyugunyugu, kizwi kandi nka flap valve, ni valve igenga imiterere yoroshye.Ibinyugunyugu birashobora gukoreshwa muguhindura uburyo bwo kugenzura imiyoboro yumuvuduko muke.Ikinyugunyugu kinyugunyugu gikoresha disiki cyangwa isahani yikinyugunyugu nka disiki, izenguruka uruziga rwa valve kugirango ifungure kandi ifunge.
Imyanda y'ibinyugunyugu irashobora gukoreshwa mugucunga imigendekere yubwoko butandukanye bwamazi nkumwuka, amazi, amavuta, ibitangazamakuru bitandukanye byangirika, ibyondo, amavuta, ibyuma byamazi nibitangazamakuru bya radio.Ifite cyane cyane uruhare rwo gukata no gutembera kumuyoboro.Gufungura no gufunga igice cyikinyugunyugu ni isahani yikinyugunyugu isa na disikuru izenguruka umurongo wacyo mu mubiri wa valve kugirango ugere ku ntego yo gufungura no gufunga cyangwa guhinduka.
Ibintu nyamukuru biranga ikinyugunyugu ni: ntoya ikora, umwanya muto wo kwishyiriraho nuburemere bworoshye.Dufashe DN1000 nk'urugero, ikinyugunyugu kinyugunyugu kingana na 2 T, mugihe irembo ry'irembo rigeze kuri 3.5 T, kandi ikinyugunyugu kinyugunyugu kiroroshye guhuza hamwe nibikoresho bitandukanye byo gutwara, kandi bifite igihe kirekire kandi cyizewe.Ingaruka z'ikinyugunyugu gifunze reberi ni uko iyo ikoreshejwe mu gutereta, cavitation izabaho bitewe no kuyikoresha nabi, izatera gukuramo no kwangiza intebe ya reberi, bityo rero uburyo bwo kuyihitamo neza biterwa n'ibisabwa n'akazi. imiterere.Isano iri hagati yo gufungura ikinyugunyugu nigipimo cyimigendere ihinduka cyane.Niba ikoreshwa mugucunga imigezi, ibiranga imigezi nayo bifitanye isano rya bugufi no kurwanya imiyoboro.Kurugero, niba imiyoboro ibiri yashizwemo na diameter imwe ya valve nuburyo bumwe, ariko coefficient de coiffe yimiyoboro iratandukanye, umuvuduko wimyanda nayo izatandukana cyane.Niba valve iri muburyo bunini cyane, cavitation ikunda kugaragara inyuma yicyapa, gishobora kwangiza valve.Mubisanzwe, ikoreshwa hanze ya 15 °.Iyo ikinyugunyugu kiri mu gufungura hagati, imiterere yo gufungura ikorwa numubiri wa valve nu mpera yimbere yicyapa cyibinyugunyugu iba yibanze kuri shitingi, kandi impande zombi zigakora leta zitandukanye.Impera yimbere yisahani yikinyugunyugu kuruhande rumwe igenda yerekeza ku cyerekezo cy’amazi atemba, naho urundi ruhande rugana ku cyerekezo cy’amazi atemba.Kubwibyo, uruhande rumwe rwumubiri wa valve hamwe na plaque ya valve ikora gufungura ishusho ya nozzle, naho urundi ruhande rusa nugukingura kumera.Umuvuduko w umuvuduko kuruhande rwa nozzle urihuta cyane kurenza kuruhande rwa trottle, kandi umuvuduko mubi uzabyara munsi ya valve kuruhande, akenshi kashe ya reberi izavaho.Umuyoboro ukora wa kinyugunyugu uratandukanye no gufungura no gufungura no gufunga icyerekezo cya valve.Kubibinyugunyugu bitambitse, cyane cyane umubyimba munini wa diameter, kubera ubujyakuzimu bw'amazi, itara ryatewe no gutandukanya imitwe yo hejuru no hepfo yumutwe wa valve ntishobora kwirengagizwa.Mubyongeyeho, mugihe inkokora yashizwe kuruhande rwimbere rwa valve, habaho kubogama kandi urumuri ruziyongera.Iyo valve iri mu gufungura hagati, uburyo bwo gukora bugomba kwifungisha bitewe nigikorwa cyumuriro wamazi.
Ikinyugunyugu ni ubwoko bwa valve ikoresha ubwoko bwa disiki yo gufungura no gufunga ibice kugirango uhindukire inyuma nka 90 ° kugirango ufungure, ufunge cyangwa uhindure urujya n'uruza.Ikinyugunyugu ntigifite gusa imiterere yoroshye, ingano nto, uburemere bworoshye, gukoresha ibikoresho bike, ingano ntoya yo kwishyiriraho, moteri ntoya yo gutwara, gukora byoroshye kandi byihuse, ariko kandi ifite imikorere myiza yo kugenzura imigezi no gufunga no gufunga ibimenyetso icyarimwe.Bumwe mu bwoko bwihuta bwihuta.Ibinyugunyugu bikoreshwa cyane.Ubwoko nubwinshi bwimikoreshereze yabyo biracyaguka, kandi biratera imbere bigana ubushyuhe bwinshi, umuvuduko mwinshi, diameter nini, gufunga cyane, kuramba, kuranga ibintu byiza cyane, hamwe nibikorwa byinshi bya valve.Kwizerwa kwayo nibindi bipimo ngenderwaho bigeze kurwego rwo hejuru.
Ikinyugunyugu kinyugunyugu ubusanzwe kiri munsi ya 90 ° kuva gifunguye kugeza gifunze byuzuye.Ikinyugunyugu n'ikinyugunyugu nta bushobozi bwo kwifungisha.Kugirango ushireho isahani yikinyugunyugu, hagomba gushyirwaho kugabanya ibikoresho byinyo.Gukoresha ibikoresho byo kugabanya inyo ntabwo bifasha gusa isahani yikinyugunyugu kugira ubushobozi bwo kwifungisha, bituma isahani yikinyugunyugu ihagarara kumwanya uwariwo wose, ariko kandi inanoza imikorere ya valve.Ibiranga inganda zidasanzwe zinyugunyugu: kurwanya ubushyuhe bwinshi, umuvuduko ukabije wumuvuduko, diameter nini yizina ya valve, umubiri wa valve ukozwe mubyuma bya karubone, kandi impeta ya kashe ya plaque ikozwe nimpeta yicyuma aho kuba reberi.Ibinyugunyugu binini cyane byo mu bushyuhe bwo mu bwoko bwa kinyugunyugu bikozwe no gusudira ibyuma kandi bigakoreshwa cyane cyane mu miyoboro ya gazi ya gazi no mu miyoboro ya gaze kubitangazamakuru bifite ubushyuhe bwinshi.
