Muri 30 ,.ikinyugunyuguyahimbwe muri Amerika, yerekanwa mu Buyapani mu myaka ya za 50, kandi yakoreshejwe cyane mu Buyapani mu myaka ya za 60, kandi yazamuwe mu Bushinwa nyuma ya za 70. Kugeza ubu, ibinyugunyugu hejuru ya DN300 mm kwisi byasimbuye buhoro buhoro indangagaciro. Ugereranije naamarembo, ibinyugunyugu bifite igihe gito cyo gufungura no gufunga, itara rito ryo gukora, umwanya muto wo kwishyiriraho nuburemere bworoshye. Dufashe DN1000 nk'urugero, ikinyugunyugu kinyugunyugu kigera kuri 2T, na valve y'irembo igera kuri 3.5T, kandi ikinyugunyugu kinyugunyugu kiroroshye guhuza hamwe nibikoresho bitandukanye byo gutwara, hamwe nigihe kirekire kandi cyizewe.
Ibibi bya kashe ya rubberikinyugunyuguni uko iyo ikoreshejwe mugukubita, cavitation izabaho kubera gukoresha nabi, bizatera intebe ya reberi gukuramo no kwangirika. Mu myaka yashize, Ubushinwa nabwo bwateje imbere ibyuma bifunga ikinyugunyugu gifunze, kandi mu myaka yashize, Ubuyapani nabwo bwateje imbere ikibaya kimeze nk'ikinyugunyugu kirwanya cavitation, kunyeganyega gake ndetse n'urusaku ruke.
Ubuzima bwa serivisi bwicyicaro rusange ni imyaka 15-20 kuri rubber na 80-90 kumyuma mubihe bisanzwe. Ariko, uburyo bwo guhitamo neza biterwa nibisabwa kugirango akazi gakorwe.
Isano iri hagati yo gufungura aikinyugunyugukandi igipimo cyo gutembera ni umurongo kandi ugereranije. Niba ikoreshwa mugucunga umuvuduko, imigendekere yacyo nayo ifitanye isano rya bugufi no kurwanya imiyoboro yimiyoboro, nka diametre nuburyo bwa valve byashyizwe mumiyoboro yombi birasa, kandi coefficente yo gutakaza imiyoboro iratandukanye. , kandi umuvuduko wikigereranyo cya valve uzaba utandukanye cyane.
Niba valve iri muburyo bunini bwo gutembera, inyuma yicyapa cya plaque ikunda kwibasirwa, kandi haribishoboka ko byangiza valve, kubwibyo bikoreshwa muri rusange hanze ya 15 °.
Iyo ikinyugunyugu kiri mu gufungura hagati, imiterere yo gufungura yakozwe naindangaumubiri nu mpera yimbere yisahani yikinyugunyugu iba yibanze kuri shitingi ya valve, kandi impande zombi zigize leta zitandukanye, impera yimbere yicyapa kinyugunyugu kuruhande rumwe igenda yerekeza ku cyerekezo cyamazi atemba, kurundi ruhande rukerekeza kuruhande. y'amazi atemba rero, umubiri wa valve kuruhande rumwe hamwe na plaque ya valve ikora gufungura ishusho ya nozzle, naho kurundi ruhande rusa no gufungura umwobo umeze nk'urwobo, uruhande rwa nozzle rwihuta cyane kurenza uruhande rwa trottle, na umuvuduko mubi uzabyara munsi ya trottle kuruhande, kandi kashe ya rubber ikunze kugwa.
Umuyoboro ukora wa kinyugunyugu, bitewe nicyerekezo gitandukanye cyo gufungura no gufungura icyerekezo cya valve, agaciro kayo karatandukanye, hamwe na kinyugunyugu kinyugunyugu gitambitse, cyane cyane nini ya diameter nini, kubera ubujyakuzimu bwamazi, itara ryatewe no gutandukanya umutwe wo hejuru no hepfo ya valve shaft ntishobora kwirengagizwa. Mubyongeyeho, iyo inkokora ishyizwe kuruhande rwimbere rwa valve, havuka urujya n'uruza, kandi torque iriyongera. Iyo valve iri mu gufungura hagati, uburyo bwo gukora bugomba kwifungisha bitewe nigikorwa cyumuriro wamazi.
