Ni izihe nyungu n'ibibi byaglobe?
Gufungura no gufunga ibice byafunzwe-bifunga amababi manini yagutse, kandi hejuru yikidodo kiringaniye cyangwa kirahuzagurika, kandi kigenda kumurongo ugana kumurongo wo hagati wamazi.Uburyo bwo kugenda bwinkoni bufite ubwoko bwinkoni yo guterura (uruti rwa valve ruzamurwa kandi rumanurwa, uruziga rwamaboko ntiruzamuka), kandi hariho ubwoko bwikizunguruka buzunguruka (uruziga rwamaboko nigiti cya valve bizunguruka kandi bizamuka hamwe, kandi ibinyomoro bishyirwa kumubiri wa valve).Guhagarika valve ikwiranye gusa no gufungura byuzuye no gufunga byuzuye, guhinduka no guterana ntibyemewe.
Guhagarika valve nigikoresho cyo gufunga ku gahato, iyo rero iyo valve ifunze, igitutu kigomba gukoreshwa kuri flap kugirango uhate hejuru yikidodo.Iyo igikoresho cyinjiye muri valve itandatu uhereye munsi ya disiki ya valve, kurwanya imbaraga imbaraga zikeneye gutsinda ni imbaraga zo guteranya uruti rwa valve hamwe no gupakira hamwe nigitutu giterwa nigitutu cyikigereranyo.Imbaraga zo gufunga valve ziruta imbaraga zo gufungura valve, bityo valve Diameter yinkoni igomba kuba nini, bitabaye ibyo umuyoboro wibiti bya valve bizananirana.Mumyaka yashize, kuva havuka kwifungisha-kwifungisha, icyerekezo cyo hagati cyerekezo cyo gufunga cyahindutse kuva hejuru ya clave ya clavike mu cyuho cya valve.Muri iki gihe, munsi yigikorwa cyumuvuduko wo hagati, imbaraga zo gufunga valve ni nto, mugihe imbaraga zo gufungura valve nini.Diameter irashobora kugabanuka ukurikije.Mugihe kimwe, munsi yibikorwa byikigereranyo, ubu bwoko bwa valve nabwo burakomeye.valve yigihugu cyanjye “Sanhua” yigeze guteganya ko icyerekezo gitemba cya valve ihagarara igomba kuva hejuru kugeza hasi.
Iyo gufunga valve bifunguye, iyo uburebure bwo gufungura disiki ari 25% -30% ya diameter nominal, imigezi igeze kuri byinshi, byerekana ko valve yageze kumwanya wuzuye.Kubwibyo, imyanya ifunguye yuzuye yo gufunga valve igomba kugenwa na stroke ya disiki ya valve.
Ihagarikwa rya valve rishobora kugabanywamo: guhagarika valve, urudodo rwo hejuru uruti rwo guhagarika valve, urudodo rwo hasi uruti rwihagararaho, kugororoka-kunyuze guhagarara guhagarara, impande zihagarara, inzira-eshatu zihagarara, icyerekezo gihagarara, icyerekezo gihagarara, inshinge globe.
Ibyiza: imiterere yoroshye, gukora neza no kuyitaho.
Gukubita inkoni ni nto, kandi igihe cyo gufungura no gufunga ni gito.
Imikorere myiza yo gufunga, guterana gato hagati yikimenyetso, no kuramba.
Ibibi:
Kurwanya amazi ni binini, kandi imbaraga zisabwa mu gufungura no gufunga ni nini.
Ntibikwiye kubitangazamakuru bifite ibice, ubukonje bwinshi kandi byoroshye kokiya.
Imikorere idahwitse
Icyitonderwa cyo kwishyiriraho no kubungabunga: Guhagarika valve ikoreshwa nuruziga rwamaboko hamwe nigitoki birashobora gushyirwaho kumwanya uwo ariwo wose wumuyoboro.
Intoki, amaboko hamwe nuburyo bukoreshwa ntabwo byemewe gukoreshwa mu guterura.Icyerekezo gitemba cyikigereranyo kigomba guhuza nicyerekezo cyumwambi cyerekanwe kumubiri wa valve.
