Nkuko twese tubizi, igice cyonyine cy'ikinyabiziga gihuye n'ubutaka ni ipine. Mu by'ukuri amapine agizwe n'ibintu byinshi bikenewe kugira ngo ipine ikore neza kandi yemerere imodoka kugera ku rwego rwayo. Amapine ni ingenzi ku mikorere y'ikinyabiziga, ibyiyumvo byacyo, uburyo kiyitwara, ndetse n'umutekano wacyo. Si amapine ya kabutura gusa atuma umutekano ukomeza mu gihe cyo gutwara, ahubwo n'agace k'ipine kayo ni ingenzi mu ipine.
Valve y'ipine ni iki?
Valve y'ipine ni igikoresho cy'umubiri w'ipine cyigenga, iyo gifunguwe, cyemerera umwuka kwinjira mu mwanya w'ipine cyangwa umuyoboro udafite umuyoboro, hanyuma kigafunga burundu kigafunga kugira ngo umwuka udasohoka mu ipine cyangwa umuyoboro. Uretse amapine akomeye, andi mapine yose cyangwa imiyoboro y'imbere igomba gushyirwamo umwuka igomba gushyirwamo umwuka hamwe n'iki gikoresho.
Ubwoko bungana iki bwa Valve y'Amapine?
Uburyo valve z'amapine zishyirwa mu byiciro buterwa n'ibice byashyizwe mu byiciro. Bishobora gushyirwa mu byiciro hakurikijwe icyitegererezo cyakoreshejwe, cyangwa bishobora gushyirwa mu byiciro hakurikijwe ibikoresho bya valve. Mu bipimo bitandukanye, uburyo bwo gushyira mu byiciro nabwo buratandukanye. Ibi bikurikira bishobora gushyirwa mu byiciro hakurikijwe uburyo bwo guteranya kandi bishobora kugabanywamo ibice bibiri:gushyiramo umupira w'ingufunaicyuma gifungamo umuvuduko mwinshi.
Valves zo gushyiramo imiyoboro zidafite imiyoboro
Valve idafite umuyoboro ifite umuvuduko ntarengwa w’ipine ikonje wa 65psi kandi yagenewe gukoreshwa cyane cyane ku modoka, amakamyo yoroheje n’amakamyo yoroheje. Valve zikoresha umuyoboro zishobora gushyirwaho imyobo ifite umurambararo wa 0.453" cyangwa 0.625" mu mpande, kandi ziboneka mu burebure kuva kuri 7/8" kugeza kuri 2-1/2". Muri make, valve iza ifite umupfundikizo wa pulasitiki nk'uko bisanzwe, ariko ishobora no guhindurwa ikoresheje umupfundikizo wa chrome cyangwa umupfundikizo w'umuringa kugira ngo ijyane n'ishusho y'umuziga.
Valves z'icyuma zishyiramo umuvuduko mwinshi
Valve y'icyuma ikoresha umuvuduko mwinshi ishobora kwinjira hafi ya buri bwoko bw'imodoka, kandi turasaba valve z'icyuma ku modoka zishobora gukoreshwa cyane n'imodoka zishobora kugendeshwa cyane ku muvuduko urenga 130 mph. Valve y'icyuma ifunga ipine na gasket ya rubber mugihe ikomeza nut ifata. Nubwo imiterere n'imiterere ya valves z'icyuma bishobora gutuma nut ifata ipine iba yihishe imbere mu pine cyangwa ikagaragara inyuma, izifite nut ifata ipine inyuma zitanga inyungu zifatika zo kwemerera nut ifata ipine gusuzumwa no guhindurwa hatabayeho gukuraho ubukana bw'ipine mu pine. Valve z'icyuma zifata ipine zemerera umuvuduko ntarengwa wa psi 200 kandi zishobora gukoreshwa mu gushyiraho imyobo ya 0.453" cyangwa 0.625" ku mpande, ndetse n'ibindi bikoresho byihariye nka 6mm (.236") cyangwa 8mm (.315").
Nigute wamenya ubwiza bwa value y'ipine?
Ku bijyanye na valve ya rubber, ubwiza bw'ibikoresho bitandukanye nabwo buratandukanye. Valve igizwe ahanini na rubber, stem ya valve n'inyuma ya valve. Muri rubber zisanzwe harimo rubber karemano na rubber ya EPDM. Ibikoresho bya valve biboneka mu mahitamo ya brass na aluminium. Valve ikunze gukorwa mu nteruro y'umuringa, ariko amasoko amwe yo mu karere ahitamo gukoresha zinc core kuko igiciro cya zinc core gihendutse. Muri rusange, kuri valve nziza, turasaba gukoresha stem ya brass n'inyuma ya valve.
Ese hari itandukaniro riri hagati ya Rubber Naturel na Rubber ya EPMD?
Mbere na mbere, irabu karemano iboneka mu bimera nk'ibiti bya rubu, mu gihe irabu ya EPDM ikorwa mu buryo bw'ubukorano; ibikoresho bya rubu bya EPDM birakomera kandi bigacika intege nyuma yo gusaza, mu gihe ibikoresho bya rubu karemano byoroha kandi bigafatana nyuma yo gusaza.
Umusaruro wo gusaza ubushyuhe wa EPDM rubber ni mwiza kurusha uwa rubber karemano; imikorere yo gushyushya no kurwanya ingese ya rubber karemano nayo ni myiza kuruta uwa rubber karemano; imikorere yo kudaca amazi, amazi ashyushye cyane n'umwuka w'amazi ya rubber ya EPDM rubber Ni nziza cyane kuruta rubber karemano, imikorere ihebuje ni ubudahangarwa bw'umwuka mwinshi, ndetse iruta rubber ya fluorine; ikindi cyiza ni uko rubber ya EPDM ifite ingano nini yuzuza, ishobora kuzuzwamo umukara n'ibindi byuzuza. Ntibigira ingaruka ku miterere myinshi y'ibicuruzwa n'ibindi.
Bityo, hamwe n'isesengura ryavuzwe haruguru, ihurizo ry'ibikoresho twasaba kuri valve nziza cyane niEPDM rubber + Umutsima w'umuringa + Ishingiro ry'umuringa.
