Uwiteka imipirani irembo ryo gufungura no gufunga.Icyerekezo cyerekezo cy irembo ni perpendicular yerekeza kumazi.Irembo ry'irembo rishobora gukingurwa gusa no gufungwa byuzuye, kandi ntirishobora guhinduka cyangwa guterwa.Irembo ry'irembo rifunze hamwe no guhuza intebe ya valve na plaque.Mubisanzwe, ubuso bwa kashe buzaba bugaragaramo ibikoresho byuma kugirango byongere imbaraga zo kwambara, nko kugaragara 1Cr13, STL6, ibyuma bitagira umwanda, nibindi. Irembo rifite irembo rikomeye n irembo ryoroshye.Ukurikije amarembo atandukanye, valve y irembo igabanijwemo irembo rikomeye hamwe na valve yoroheje.

Gufungura no gufunga igice cyaimipirani irembo, kandi icyerekezo cyerekezo cy irembo ni perpendicular yerekeza ku cyerekezo cyamazi.Irembo ry'irembo rishobora gukingurwa gusa no gufungwa byuzuye, kandi ntirishobora guhinduka cyangwa guterwa.Irembo rifite ubuso bubiri.Ibice bibiri bifunga kashe yuburyo bukoreshwa muburyo bwamarembo ya valve ikora ishusho ya wedge.Inguni ya wedge iratandukanye nibipimo bya valve, mubisanzwe 5 °, na 2 ° 52 ′ mugihe ubushyuhe bwo hagati butari hejuru.Irembo rya valve wedge irashobora gukorwa muri rusange, bita irembo rikomeye;irashobora kandi gukorwa mumarembo ashobora kubyara déformasiyo nkeya kugirango atezimbere ubukorikori bwayo kandi ashobore gutandukana nu mpande zifunze mugihe cyo gutunganya.Isahani yitwa irembo ryoroshye.Iyo valve y irembo ifunze, ubuso bwa kashe burashobora gufungwa gusa nigitutu giciriritse, ni ukuvuga, gushingira kumuvuduko wo hagati kugirango ukande hejuru yikimenyetso cyumuryango kugeza kuntebe ya valve kurundi ruhande kugirango ushireho ikimenyetso. ubuso, burimo kwifungisha.Ibyinshi mu marembo bifunze ku gahato, ni ukuvuga, iyo valve ifunze, irembo rigomba guhatirwa ku ntebe ya valve n'imbaraga zo hanze kugirango harebwe ubukana bwa kashe.Irembo ry'irembo ry'irembo rigenda neza hamwe n'uruti rwa valve, rwitwa lift-inkoni yo mu irembo, ruzwi kandi nk'izamuka-inkoni y'irembo.Mubisanzwe, hariho insinga za trapezoidal kumutwe.Binyuze mu mbuto hejuru ya valve hamwe nuyobora umurongo ku mubiri wa valve, icyerekezo kizunguruka gihinduka umurongo ugororotse, ni ukuvuga, itara rikora rihinduka muburyo bwo gukora.Iyo valve ifunguye, mugihe uburebure bwo kuzamura irembo bungana ninshuro 1: 1 z'umurambararo wa valve, umuyoboro wamazi ntuburizwamo, ariko uyu mwanya ntushobora gukurikiranwa mugihe ukora.Mu mikoreshereze nyayo, apex ya stem stem ikoreshwa nkikimenyetso, ni ukuvuga, umwanya udashobora gukingurwa, nkumwanya wuzuye wuzuye.Kugirango uzirikane ibintu bifunga biterwa nubushyuhe bwubushyuhe, mubisanzwe bifungurwa kumwanya wo hejuru, hanyuma ugasubira kuri 1 / 2-1, nkumwanya wa valve yuzuye.Kubwibyo, umwanya wuzuye wa valve ugenwa ukurikije umwanya w irembo, ni ukuvuga inkoni.Kubirindiro bimwe byamarembo, ibinyomoro byuruti bishyirwa kumuryango, kandi kuzunguruka kwintoki zitwara uruti rwa valve kuzunguruka, bigatuma irembo rizamuka.Ubu bwoko bwa valve bwitwa kuzenguruka stem gate valve, cyangwa irembo ryijimye ryijimye.
