Sunan Ingilishi na baturin gubar-acid mai sarrafa bawul shine Batirin Gubar Kayyade Valve (batir VRLA a takaice).Akwai bawul ɗin shaye-shaye mai hanya ɗaya (wanda ake kira da aminci bawul) akan murfin.Aikin wannan bawul shine fitar da iskar gas a lokacin da adadin iskar da ke cikin baturin ya wuce wani ƙima (yawanci ana bayyana shi da ƙimar ƙarfin iska), wato lokacin da iskan da ke cikin baturin ya tashi zuwa wani ƙima.Bawul ɗin iskar gas yana buɗewa ta atomatik don fitar da iskar, sannan ta rufe bawul ɗin ta atomatik don hana iska shiga cikin baturin.
Wahalar rufe batirin gubar-acid shine electrolysis na ruwa yayin caji.Lokacin da cajin ya kai ga wani ƙarfin lantarki (gaba ɗaya sama da 2.30V/cell), ana fitar da iskar oxygen akan tabbataccen lantarki na baturi, kuma ana fitar da hydrogen akan mummunan lantarki.A gefe guda kuma, iskar da ake fitarwa tana fitar da hazo na acid don gurbata muhalli;Batirin gubar-acid mai sarrafa bawul samfur ne da aka haɓaka don shawo kan waɗannan gazawar.Siffofin samfurinsa sune:
(1) Multi-element high quality-grid gami da ake amfani da su inganta overpotential na gas saki.Wato, alƙawarin grid ɗin batir na yau da kullun yana fitar da iskar gas lokacin da ya wuce 2.30V/cell (25°C).Bayan yin amfani da allurai masu inganci masu inganci, ana fitar da iskar gas lokacin da zafin jiki ya wuce 2.35V/monomer (25°C), wanda hakan yana rage yawan iskar gas da aka fitar.
(2) Bari mummunan lantarki ya sami ƙarfin da ya wuce kima, wato, 10% fiye da ƙarfin lantarki fiye da ingantaccen lantarki.A mataki na gaba na caji, iskar oxygen ɗin da tabbataccen electrode ɗin ke fitarwa yana tuntuɓar wutar lantarki mara kyau, yana amsawa, kuma yana sake haɓaka ruwa, wato, O2+2Pb→2PbO+2H2SO4→H2O+2PbSO4, ta yadda mummunan electrode yana cikin yanayin da ba a caji. saboda aikin oxygen, don haka ba a samar da hydrogen ba.Oxygen na tabbataccen electrode yana shiga ne ta hanyar gubar da ba ta dace ba, sannan kuma ta ƙara rikiɗa zuwa ruwa, wanda shine abin da ake kira cathode absorption.
