Irembo ry'icyuma

Igice cyo gufungura no gufunga igice cyuma cyuma kitagira umuyonga ni irembo, kandi icyerekezo cyerekezo cy irembo ni perpendikulire yerekeza kumazi. Irembo ry'icyuma ridafite ingese rifite ubuso bubiri. Ibice bibiri bifunga kashe ya moderi ikunze gukoreshwa cyane ikora amarembo, kandi impande zinyuranye ziratandukana. Irembo rya valve wedge irashobora gukorwa muri rusange, bita irembo rikomeye; irashobora kandi gukorwa mumarembo ashobora kubyara ihinduka rito kugirango arusheho kuyikora no kwishyura indinganizo yo gufunga impande zombi mugihe cyo gutunganya. Isahani yitwa irembo ryoroshye. Ibikoresho by'ibikoresho bitagira umuyonga bigabanijwemo CF8, CF8M, CF3, CF3M, 904L, Duplex Icyuma (4A, 5A, 6A).
Ubwoko bwibyuma bitagira umuyonga birashobora kugabanywa mumarembo ya wedge hamwe na parike iringaniye ukurikije imiterere ya kashe. Inzugi z'irembo zishobora kugabanywamo: ubwoko bw'irembo rimwe, ubwoko bubiri bw'irembo n'ubwoko bw'irembo bworoshye; iringaniza ryubwoko bwamarembo irashobora kugabanywa mubwoko bumwe bwubwoko bwubwoko bubiri. Igabanijwe ukurikije urudodo rwumwanya wikibaho, irashobora kugabanywamo ubwoko bubiri: gufungura amarembo yikibiriti hamwe nigitereko cyijimye. Ubu bwoko bwa valve bugomba gushyirwaho muburyo butambitse.
Iyo valve ifunguye, iyo uburebure bwo guterura bw irembo bungana na 1: 1 inshuro ya diameter ya valve, inzira ya fluid irakinguwe rwose, ariko iyi myanya ntishobora gukurikiranwa mugihe ikora. Mugukoresha nyabyo, apex ya stem stem ikoreshwa nkikimenyetso, ni ukuvuga, umwanya udashobora gukingurwa, nkumwanya wacyo wuzuye. Kugirango uzirikane ibintu bifunga bitewe nubushyuhe bwubushyuhe, ubusanzwe valve ifungura kumwanya wa apex hanyuma igasubizwa inyuma na 1/2 kugeza kuri 1 nkumwanya wuzuye ufunguye. Kubwibyo, imyanya yuzuye ya valve igenwa nu mwanya w irembo (ni ukuvuga inkoni).
Mu marembo amwe n'amwe, ibiti by'uruti bishyirwa ku irembo, kandi kuzunguruka kw'intoki bigatwara kuzenguruka uruti rwa valve kugirango uzamure irembo. Ubu bwoko bwa valve bwitwa kuzunguruka stem gate valve cyangwa valve yijimye.
