Uwitekairemboni 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 rifunzwe no guhuza hagati yintebe ya plaque.Mubisanzwe, hejuru yikidodo hazaba hagaragaramo ibyuma kugirango byongere imbaraga zo kwambara, nko kugaragara 1Cr13, STL6, ibyuma bitagira umwanda, nibindi. Irembo rifite irembo rikomeye n irembo ryoroshye.Ukurikije amarembo atandukanye, irembo ry irembo rigabanijwemo irembo rikomeye hamwe n irembo ryoroshye.

Gufungura no gufunga igice cyurugi ni irembo, kandi icyerekezo cyerekezo cy irembo ni perpendicular yerekeza kumazi.UwitekairemboBirashobora gukingurwa gusa no gufungwa byuzuye, kandi ntibishobora guhinduka cyangwa guhindurwa.Irembo rifite ubuso bubiri.Ibice bibiri bifunga kashe yuburyo bukoreshwa muburyo bwamarembo ya valve ikora ishusho.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 kumpande zifatika mugihe cyo gutunganya.Isahani yitwa irembo ryoroshye.Iyo irembo ry'irembo rifunze, ubuso bwa kashe burashobora gufungwa gusa nigitutu giciriritse, ni ukuvuga, kwishingikiriza kumuvuduko wo hagati kugirango ukande hejuru yikimenyetso cyumuryango wintebe kurundi ruhande kugirango ushireho ikimenyetso. ubuso, burimo kwifungisha.Ibyinshi mu marembo bifunze ku gahato, ni ukuvuga, iyo valve ifunze, irembo rigomba guhatirwa ku cyicaro cyimbaraga nimbaraga zo hanze kugirango harebwe neza.Irembo ry irembo ryimodoka rigenda neza hamwe nigitereko cya valve, cyiswe lift-inkoni ya rugi, kizwi kandi nkizamuka-inkoni yumuryango.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, torque ikora ihindurwamo imbaraga.Iyo valve ifunguye, iyo kuzamura uburebure bw irembo bingana na 1: 1 inshuro ya diametre ya 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 wacyo wuzuye.Kugirango uzirikane ibintu byo gufunga biterwa nubushyuhe bwubushyuhe, mubisanzwe bifungurwa kumwanya wo hejuru, hanyuma ugasubira kuri 1 / 2-1, nkumwanya wa valve ifunguye neza.Kubwibyo, imyanya yuzuye ya valve igenwa ukurikije umwanya w irembo, ni ukuvuga inkoni.Kuri bamweamarembo, ibiti by'uruti bishyirwa ku irembo, kandi kuzunguruka kw'intoki bituma igiti cya valve kizunguruka, bigatuma irembo rizamura.Ubu bwoko bwa valve bwitwa kuzunguruka stem gate valve, cyangwa valve yijimye.
