6.Inyubako yizewe yo gufunga intebe
Gufunga intebe bikorwa binyuze mu bikoresho bibiri birekura intebe, bishobora kureremba mu buryo bw'uruhande kugira ngo bizibe amazi, harimo no gufunga umupira no gufunga umubiri. Gufunga intebe ya valve ku muvuduko muke bigaragazwa no gufunga umupira mbere yo kuyifunga. Byongeye kandi, ingaruka za piston z'intebe ya valve zakozwe neza, bigatuma ifunga umupira ukabije n'umuvuduko w'icyuma ubwacyo. Ubwoko bubiri bukurikira bwo gufunga umupira burashobora gukorwa.
7. Gufunga rimwe
(Kugabanya Umuvuduko mu buryo bwikora mu mwobo wo hagati wa Valve) Muri rusange, imiterere imwe yo gufunga ikoreshwa. Ni ukuvuga ko hariho gufunga hejuru gusa. Kubera ko intebe zo gufunga zikozwe mu mpande zo hejuru n'izo hasi zikoreshwa, umwobo w'imbere wa valve ushobora gutsinda ingaruka zo gufunga mbere y'isoko, kugira ngo intebe irekurwe mu mupira kandi ibone umuvuduko wikora ugana ku gice cyo hasi. Uruhande rwo hejuru: Iyo intebe igenda ku ruhande rw'umwobo, umuvuduko "P" ukoreshwa ku gice cyo hejuru (injira) utanga imbaraga zisubira inyuma kuri A1, Kubera ko A2 iri hejuru ya A1, A2-A1 = B1, imbaraga kuri B1 zizasunika intebe ku mupira kandi zigafunga igice cyo hejuru cyane.
8. Gufunga kabiri (Piston ebyiri)
Valve y'umupira w'umuyoboro wa trunnion ishobora gushushanywa ifite imiterere ibiri yo gufunga mbere na nyuma y'umupira kugira ngo ikoreshwe mu buryo bwihariye ndetse n'ibisabwa n'umukoresha. Ifite ingaruka ebyiri za piston. Mu gihe gisanzwe, valve muri rusange ifata intebe y'ibanze. Iyo intebe y'ibanze yangiritse igatera gusohoka, intebe y'ibanze ishobora gukora akazi ko gufunga no kongera ubwizerwe bwo gufunga. Intebe ifata imiterere ihujwe. Agace k'ibanze ni agace k'icyuma kuva ku cyuma kugera ku cyuma. Agace k'ibanze ni impeta ya fluorine rubber O ishobora kwemeza ko valve y'umupira ishobora kugera ku rwego rwo gufunga. Iyo itandukaniro ry'umuvuduko riri hasi cyane, intebe y'ibanze izakanda umupira mu gihe cy'impeshyi kugira ngo ikore intebe y'ibanze. Iyo itandukaniro ry'umuvuduko rizamutse, imbaraga zo gufunga intebe n'umubiri ziyongera ku buryo bifunga neza intebe n'umupira kandi bitume habaho imikorere myiza yo gufunga.
Gufunga by'ibanze: Hejuru y'amazi.
Iyo itandukaniro ry'umuvuduko riri hasi cyangwa nta tandukaniro ry'umuvuduko ririho, intebe ireremba izagenda ku ruhande rw'umugozi munsi y'ingufu z'impeshyi hanyuma inyure intebe yerekeza ku mupira kugira ngo ikomeze gufunga neza. Iyo intebe y'umugozi iri hejuru y'imbaraga zikoreshwa ku gace A1, A2- A1 = B1. Bityo, imbaraga ziri muri B1 zizasunika intebe yerekeza ku mupira maze igice cyo hejuru kibe gifunga neza.
Gufunga igice cya kabiri: Kumanuka.
Iyo itandukaniro ry'umuvuduko riri hasi cyangwa nta tandukaniro ry'umuvuduko ririho, intebe ireremba izagenda mu buryo bw'uruhande rw'imashini munsi y'imashini ikora mu mpeshyi hanyuma isunikire intebe yerekeza ku mupira kugira ngo ikomeze gufunga neza. Iyo umuvuduko wa valve P wiyongereye, imbaraga zikoreshwa ku gace A4 k'intebe ya valve hejuru y'imbaraga zikoreshwa ku gace A3, A4- A3 = B1. Kubwibyo, imbaraga ziri kuri B1 zizasunika intebe yerekeza ku mupira maze igice cyo hejuru kikazifunga neza.
9. Igikoresho cyo gufasha mu mutekano
Kubera ko valve y'umupira yakozwe ifite uburyo bwo gufunga bw'ibanze n'ubwa kabiri bufite ingaruka ebyiri za piston, kandi umwobo wo hagati ntushobora gukuraho umuvuduko wikora, valve y'umuvuduko igomba gushyirwa ku mubiri kugira ngo hirindwe ibyago byo kwangirika k'umuvuduko mwinshi mu mwobo w'umwobo bishobora kubaho bitewe no kwaguka k'ubushyuhe bw'umwuka. Guhuza valve y'umuvuduko wikora muri rusange ni NPT 1/2. Ikindi kintu kigomba kwitabwaho ni uko icyuma cy'umuvuduko wikora gisohoka mu kirere mu buryo butaziguye. Mu gihe gusukura mu kirere mu buryo butaziguye bitemerewe, turasaba ko valve y'umupira ifite imiterere yihariye yo gukuraho umuvuduko wikora mu mugezi wo hejuru igomba gukoreshwa. Reba ibi bikurikira kugira ngo umenye ibisobanuro birambuye. Nyamuneka yerekane uko bikurikirana niba udakeneye valve y'umuvuduko wikora cyangwa niba wifuza gukoresha valve y'umupira ifite imiterere yihariye yo gukuraho umuvuduko wikora mu mugezi wo hejuru.
10. Imiterere yihariye yo kugabanya umuvuduko mu buryo bwikora ku mugezi wo hejuru
