Ubwoko bwa valve y'umupira

Valve y'umupira ireremba
Umupira wavalve y'umupirairi kureremba. Mu gihe cy'igitutu kiri hagati, umupira ushobora gukora ikintu runaka ugakanda cyane ku gice cyo gufunga cy'inkombe y'aho usohoka kugira ngo urebe ko inkombe y'aho usohoka ifungirwa. Valve y'umupira iri kureremba ifite imiterere yoroshye kandi ikora neza, ariko umutwaro w'umupira ufite icyuma gikoreraho wimurirwa mu mpeta yo gufunga, bityo ni ngombwa gusuzuma niba ibikoresho byo gufunga bishobora kwihanganira umutwaro w'icyuma gikoreraho. Iyi nyubako ikoreshwa cyane mu mavali y'umupira ari hagati n'ahenshi.
Valve y'umupira wa Trunnion
Umupira wavalve y'umupiraIrahamye kandi ntigenda bitewe n'umuvuduko. Valve y'umupira idahinduka ifite intebe ya valve ireremba. Nyuma yo gushyirwamo umuvuduko n'icyuma gikoresha amashanyarazi, intebe ya valve iragenda, ku buryo impeta yo gufunga ikandagirwa cyane ku mupira kugira ngo irebe ko ifunga neza. Ubusanzwe ibyuma bishyirwa ku mpande zo hejuru n'izo hasi hamwe n'umupira, kandi torque yo gukora iba nto, ikwiriye valve zifite umuvuduko mwinshi n'umurambararo munini. Kugira ngo igabanye torque yo gukora ya valve y'umupira no kongera ubwizerwe bw'igipfundikizo, valve z'umupira zifunze amavuta zagaragaye vuba aha. Amavuta yihariye yo kwisiga ashyirwa hagati y'ubuso bwo gufunga kugira ngo hakorwe firime y'amavuta, yongera imikorere yo gufunga kandi igabanya torque yo gukora. Torque yo gukora ikwiriye cyane valve z'umupira zifite umuvuduko mwinshi n'umurambararo munini.
Valve y'umupira irashya
Umupira wa vali y'umupira ni élastic. Umupira n'impeta yo gufunga intebe ya vali byombi bikozwe mu byuma, kandi igitutu cyihariye cyo gufunga ni kinini cyane. Igitutu cy'icyuma ubwacyo ntigishobora kuzuza ibisabwa byo gufunga, kandi imbaraga zo hanze zigomba gukoreshwa. Iyi vali ikwiriye ubushyuhe bwinshi n'igitutu kinini. Umupira wa elastic uboneka ufunguye umuyoboro wa elastic ku mpera yo hepfo y'urukuta rw'imbere rw'umupira kugira ngo ubone élastic. Mu gihe ufunga umuyoboro, koresha umutwe wa verge w'inkingi ya vali kugira ngo wagure umupira hanyuma ukande intebe ya vali kugira ngo ubone élastic. Mbere yo guhindura umupira, fungura umutwe wa verge, maze umupira usubire mu ishusho yawo ya mbere, ku buryo haboneka icyuho gito hagati y'umupira n'intebe ya vali, bishobora kugabanya uburyaryate n'imbaraga z'imikorere y'ubuso bwo gufunga.
