Gushyira mu byiciro no gukoresha valve zo kugenzura
Valve yo kugenzura yerekeza ku bice bifungura n'ibifunga bya valve izengurutse kandi yishingikiriza ku buremere bwabyo n'igitutu cyabyo kugira ngo bikore igikorwa cyo guhagarika inzira yo gusubira inyuma kwa valve. Valve yo kugenzura ni valve yikora ubwayo, izwi kandi nka valve yo kugenzura, valve y'inzira imwe, valve idasubira inyuma cyangwa valve yo kwitandukanya.
Uburyo bwo gukaraba bugabanyijemo ibicevalve yo kugenzura ibizamuranavalve yo kugenzura swing. Imiterere ya valve yo kugenzura umuzamu n'imiterere ya valve y'umubumbe birasa, gusa ni ukubura umugongo wa valve wo kuyobora valve. Uburyo bwo kwinjira buva ku ruhande rw'aho yinjira (uruhande rwo hepfo), buva ku ruhande rw'aho asohoka (uruhande rwo hejuru). Iyo igitutu cy'aho yinjira kirenze uburemere bw'icyuma cyo kwinjira n'ubudahangarwa bwacyo n'igihe valve ifunguye. Ku rundi ruhande, valve irafungwa iyo icyuma gisubira inyuma. Valve yo kugenzura umuzamu ifite slant kandi ishobora kuzenguruka ku murongo w'icyuma cyo gushyiramo valve, ihame ry'imikorere risa na valve yo kugenzura umuzamu. Valve yo kugenzura ikunze gukoreshwa nk'icyuma cyo hasi cy'igikoresho cyo kuvoma, gishobora kubuza amazi gutembera inyuma. Valve yo kugenzura umuzamu n'ibyuma byo hejuru bikoreshwa hamwe, bishobora kugira uruhare mu kwitandukanya mu buryo bwizewe. Ingaruka mbi ni ubudahangarwa bwinshi no kudafunga neza iyo bifunze.
Ubwa mbere, valve yo kugenzura lift igizwe n'ubwoko bubiri buhagaze n'ubutambitse.
Imiterere y'umubiri wa valve ya valve yo kugenzura lift ni imwe n'iya valve y'isi, bityo ifite ubushobozi bwo guhangana n'amazi menshi. Valve flap inyura ku murongo wo hagati uhagaze w'umubiri wa valve. Iyo icyuma gitemba, valve flap ifungurwa hakoreshejwe uburyo bwo gukurura, kandi iyo icyuma gihagaze gutemba, valve flap igwa ku ntebe ya valve yimanitse.
Valve yo kugenzura lift ihagaze. Icyerekezo cy'umuyoboro uciriritse winjira n'aho usohoka n'icyerekezo cy'umuyoboro w'intebe ni kimwe, ubwiyongere bw'amazi ni buto ugereranije n'ubwoko bw'umuyoboro ugororotse. Valve yo kugenzura lift ihagaze ishyirwa mu muyoboro uhagaze.binyuze muri valve yo kugenzura ibitereko ishobora gushyirwa gusa mu muyoboro utambitse. Bigengwa n'ibisabwa mu gushyiraho, bikunze gukoreshwa mu gihe gito cya DN <50.
Icya kabiri, Disiki ya value yo kugenzura swing ifite ishusho y'uruziga kandi izenguruka ku murongo w'inzira y'intebe ya value.
Bitewe n'umuyoboro uri imbere muri vali, ubushobozi bwo kudakora neza kw'amazi ni buto ugereranije n'ubw'ivali yo kugenzura ko amazi atembera. Ikwiriye imiyoboro mito n'iciriritse, ifite umuvuduko muto, n'umurambararo munini (umuvuduko muto w'amazi n'umurambararo munini aho amazi atembera adahinduka kenshi). Imikorere yo gufunga ntabwo ari myiza nk'uburyo bwo guterura.
Valve zo kugenzura Swing zigabanyijemo ubwoko butatu: disiki imwe, disiki ebyiri, na disiki nyinshi. Ubwo bwoko butatu bushyirwa mu byiciro hakurikijwe umurambararo wa valve, kugira ngo hirindwe hydraulic shock iyo icyuma gihagaze gutemba cyangwa kigakomeza gusubira inyuma. Valve zo kugenzura Swing single dis muri rusange zikwiriye gukoreshwa mu buryo buringaniye. Mu gihe ukoresha valve imwe yo kugenzura Swing single dis ku miyoboro minini, ni byiza gukoresha valve yo kugenzura slow ishobora kugabanya umuvuduko w'amazi kugira ngo ugabanye umuvuduko w'amazi. Valve zo kugenzura Swing Double dis zikwiriye imiyoboro minini n'iciriritse. Valve yo kugenzura Swing Double dis ifite imiterere mito kandi yoroheje ni valve yo kugenzura ikura vuba; Valve zo kugenzura Swing Multi dis zikwiriye imiyoboro minini.Aho ishyirwa rya value yo kugenzura ko izunguruka ntirigarukira, kandi ishobora gushyirwa ku miyoboro itambitse, ihagaze, cyangwa ihengamye.
Icya gatatu, valve yo kugenzura ikinyugunyugu: ubwoko bugororotse.
Imiterere ya valve yo kugenzura ibinyugunyugu isa na valve yo kugenzura ibinyugunyugu. Imiterere yayo ni yoroshye, nta bushobozi bwo gutemba buhagije, umuvuduko w'amazi na wo ni muto. Agapfundikizo ka valve kazenguruka agace kari mu ntebe ya valve yo kugenzura. Valve yo kugenzura ubwoko bwa disiki ifite imiterere yoroshye, ishobora gushyirwa gusa ku muyoboro utambitse, kandi gufunga kwayo ni bike.
Icya kane, valve yo kugenzura diaphragm: hari imiterere itandukanye y’imiterere, yose ikoresha diaphragm nk'ibice bifungura n'ibifunga.
Bitewe n'imikorere yayo y'inyundo y'amazi, imiterere yayo yoroshye, ihendutse, kandi mu myaka ya vuba aha itera imbere vuba, imashini igenzura diaphragm irakoreshwa cyane. Ariko ikoreshwa rya imashini igenzura diaphragm n'umuvuduko wayo ribuza ibikoresho bya diaphragm.Valve yo kugenzura diaphragm ikwiriye koroshya gukora ingaruka z'amazi ku muyoboro, diaphragm ishobora kuba nziza cyane mu gukuraho uburyo bworoshye bwo guhangana n'amazi aturuka ku ngaruka, ikoreshwa muri rusange mu muyoboro w'ubushyuhe buke, cyane cyane ikwiriye imiyoboro y'amazi, ubushyuhe rusange bw'uburyo bwo kugenzura hagati ya -12 - 120 ℃ hagati y'umuvuduko wo gukora wa <1.6MPa, ariko valve yo kugenzura diaphragm ishobora gukorwa kugira ngo igere ku rugero runini, ntarengwa ishobora kugerwaho muri DN 2000mm cyangwa irenga! Ariko, valve yo kugenzura diaphragm ishobora kuba nini, DN ishobora kugera kuri 2000mm cyangwa irenga.
