Ibyiza: Imiterere yoroshye, ingano yumucyo, imikorere yoroshye, kashe nziza.
Ibibi: iyo bifunguye byuzuye, isahani ya valve (impeta ya kashe) isenywa nuburyo.
Mu buhanga bwo gushyushya, ikinyugunyugu gifite ibyuma bitatu bya kashe ya kinyugunyugu, reberi yoroshye ya kashe yikinyugunyugu.
1.4.1 Ibyuma bitatu bya kashe ya kashe yikinyugunyugu
Ibyo bita "eccentricité" bivuga igiti cya valve, isahani ya valve mumwanya ugereranije na offset. Ubusanzwe ikinyugunyugu gisanzwe ni eccentric, ni ukuvuga umurongo wa valve shaft rwagati hamwe no gufunga umurongo wo hagati (umurongo wa plate plate center) gutandukana; Kubikorwa bihanitse, ongeramo eccentricity, ni ukuvuga, umurongo wo hagati wumurongo wa valve utandukana kuva kumurongo wo hagati wa valve (umurongo wo hagati wumuyoboro); Intego ya eccentricité ni ugukuraho kashe ya mugenzi wawe nyuma yuko plaque ya valve ifunguye kuri 20¡ã, bityo bikagabanya ubushyamirane (ingaruka za CAM). Ibinyugunyugu bitatu byikinyugunyugu mubice bibiri byavuzwe haruguru hashingiwe ku kongeramo umwihariko udasanzwe - conli oblique, ni ukuvuga guhagarika icyapa cya valve (hejuru yikidodo hamwe nindege ihagaritse indege ihanamye Inguni). Ibi bituma valve iri murugendo rwa 90¡ã, gutandukana byuzuye hagati yikimenyetso, ntabwo bishimangira ingaruka za CAM gusa, ahubwo binakuraho burundu ubushyamirane; Funga valve icyarimwe, mugihe ikidodo gifunze gahoro gahoro, "ingaruka ya wedge", hamwe numuriro muto kugirango ugere cyane.

Ibyo bita "kashe ya cyuma" bivuga intebe ya valve, impeta yo gufunga ukoresheje kurwanya kwambara, kurwanya ruswa, kurwanya ubushyuhe bwinshi bwumuti mwiza wakozwe; Muri icyo gihe, mu rwego rwo kwirinda impeta n’icyicaro gikomeye, ikidodo cyashyizweho kugira ngo kibe cyoroshye, ni ukuvuga gushiraho “kashe y’icyuma cya elastike”, kugira ngo gifunge neza, gifunguye kivanze. Hamwe nuburyo “butatu bwa eccentricique”, bufatanije n '“ikimenyetso cya elastique kashe”, iyo mibande iroroshye gukora, iramba kandi ifunze neza.
Ibyuma bitatu bya eccentricale kashe yikinyugunyugu ikoreshwa muri sisitemu yo gushyushya umurongo nyamukuru nishami rikuru. Calibre DN300 cyangwa irenga.
Ibicuruzwa bitatu bitumizwa mu mahanga bya kashe ya kinyugunyugu nta cyerekezo bifite, ariko muri rusange byasabwe icyerekezo cyo kwishyiriraho, ntibigomba guhinduka; Icyerekezo cyimbere mu gihugu, rusange ihindagurika kuruta itandukaniro ryimbere ryurwego rusohoka cyangwa urwego rumwe kugeza kuri ebyiri, ntishobora guhinduka. Niba gusudira kumuyoboro utambitse, valve igomba gufungwa kugirango irinde impeta ya kashe; MU RUBANZA rwo gusudira VERTICAL VERTICAL, valve igomba gufungwa kandi amazi akongerwamo plaque ya valve mugihe cyo gusudira kugirango azimye icyuma cyo gusudira. Iyo BISHYIZWE MU muyoboro wa HORIZONTAL, birasabwa ko umwanya wuruti uhinduka utambitse cyangwa uhagaritse kugirango urebe neza ko icyuma cyo hasi gifite isuku.
1.4.2 Rubber yoroshye kashe yikinyugunyugu
Isahani y'ibinyugunyugu isanzwe isizwe icyuma cyitwa nodular, kandi impeta yo gufunga ni reberi. Ibikoresho bifunga kashe biratandukanye, imikorere iratandukanye. Bikunze gukoreshwa ni: Dingqing reberi, ubushyuhe bukoreshwa bwa 12¡æ a + 82¡æ; Rubber ya Ethylene propylene, ubushyuhe bukoreshwa 45¡æ a + 135¡æ; Ubushyuhe bwihanganira Ethylene propylene reberi, ibereye ubushyuhe bwa 20¡æ + 150¡æ.
Ubushyuhe bwo gushyushya bukunze gukoreshwa muri sandwich (D371X), flange (D341X). DN125 munsi yimashini iboneka (D71, D41X). Ikinyugunyugu cya wafer ni gito kandi cyoroshye, gufungura no gufunga byihuse, byoroshye gukora, byoroshye gushiraho, byoroshye kubungabunga, gufunga neza no guhindura imikorere, imikorere ihenze cyane, bityo rero bigomba kwakirwa cyane. Ikimenyetso cyoroshye kinyugunyugu ntigifite icyerekezo, gishobora gushyirwaho uko bishakiye.
Iyo ikinyugunyugu kiri mububiko, isahani ya valve igomba gukingurwa 4¡ã kugeza 5¡ã. Kugirango wirinde kwikuramo igihe kirekire no guhindura impeta ya kashe, bigira ingaruka kuri kashe.
1.5 kugenzura valve
Byitwa kandi kugenzura valve, umuryango umwe utemba. Ikoreshwa rya valve ifasha.
Ihame ryakazi: Ukurikije imbaraga zamazi ubwayo nuburemere bwa disiki, valve ihita ifungura igafunga. Nkuko izina ribigaragaza, akazi kayo ni uguhagarika uburyo bwo gusubira inyuma. Mubisanzwe ushyizwe kumasoko kugirango wirinde kwangiza inyundo.
Bikunze gukoreshwa mubushuhe bwubwubatsi nubwoko bwo guterura butambitse (H41H), ubwoko bumwe bwa swing swing (H44H), ubwoko bwikinyugunyugu bubiri (H77H).
Kugenzura valve ni icyerekezo kandi ntishobora gushyirwaho inyuma. Uburyo butandukanye bwo kugenzura indangagaciro, ukurikije imiterere yabyo, zifite igenamigambi rihamye, ntigomba gushyirwaho nabi. Ubwoko bwo gutambuka butambitse bushobora gushyirwaho gusa mumuyoboro utambitse, kandi ukemeza ko disiki ya valve iri mumiterere ihagaze; Ubwoko bumwe bwa disiki ya swing burashobora gushyirwaho gusa mumuyoboro utambitse, kandi ukemeza ko disiki ya disiki iri muburyo butambitse; Ikinyugunyugu cya kabiri gishobora gushyirwaho uko bishakiye.
