Kuzamuka Igiti Cyoroshye Gufunga Irembo Valve

Irembo ry'irembo rikoreshwa cyane mugukata ibikoresho bifite umurambararo wa DN ≥ 50mm, kandi rimwe na rimwe indangagaciro z'irembo nazo zikoreshwa mugukata ibikoresho bifite diameter nto.

Igice cyo gufungura no gufunga igice cya valve ni 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 cyane mumarembo ya valve ikora ishusho ya wedge.Inguni ya wedge iratandukanye nibipimo bya valve, mubisanzwe 50, na 2 ° 52 'mugihe ubushyuhe bwo hagati butari hejuru.Irembo ryurugi rwa wedge rushobora gukorwa muri rusange, rwitwa irembo rikomeye;irashobora kandi gukorwa mu irembo rishobora kubyara déformasiyo nkeya kugirango irusheho gukora neza no kwishyura indishyi zo gutandukanya inguni zifunze mugihe cyo gutunganya.Isahani yitwa irembo rya elastike.Irembo ry'irembo ni ibikoresho by'ingenzi bigenzura imigendekere cyangwa itanga ingano y'ifu, ibikoresho by'ingano, ibikoresho bya granulaire hamwe n'uduce duto duto.Ikoreshwa cyane muri metallurgie, ubucukuzi bw'amabuye y'agaciro, ibikoresho by'ubwubatsi, ingano, inganda z’imiti n’inganda zindi kugirango igenzure ihinduka ry’imigezi cyangwa igabanuke vuba.

Irembo ry'irembo ryerekeza cyane cyane ku bwoko bw'ibyuma byo mu irembo ry'ibyuma, bishobora kugabanywamo ibice by'irembo rya wedge, iringaniza ry'irembo, hamwe n'irembo ry'irembo ukurikije imiterere y'ubuso bwa kashe.Irembo ry'irembo rishobora kugabanywamo: ubwoko bumwe bw'irembo, ubwoko bubiri bw'irembo n'ubwoko bw'irembo bworoshye;iringaniza irembo rishobora kugabanywa mubwoko bumwe bwubwoko bwubwoko bubiri.Ukurikije urudodo rwumwanya wikibaho cya valve, irashobora kugabanywamo ubwoko bubiri: kuzamuka kumarembo yikibiriti cyizamuka hamwe nizamuka ridahagarara.

Iyo irembo ry'irembo rifunze, ubuso bwa kashe bushobora gufungwa gusa nigitutu giciriritse, ni ukuvuga, gushingira kumuvuduko wo hagati kugirango ukande hejuru yikimenyetso cya plaque kumuryango wintebe kurundi ruhande kugirango ushireho kashe ya Ikidodo cyo hejuru, kikaba ubwacyo.Byinshi mu byuma byinjira mumarembo bifunzwe kashe, nukuvuga, mugihe iyo valve ifunze, irembo rigomba gukanda kuntebe ya valve nimbaraga ziva hanze, kugirango hafatwe ikimenyetso cyo gufunga hejuru.

Irembo ry'irembo ryinjira mu murongo ugororotse hamwe n'uruti rwa valve, rwitwa kuzamura irembo ry'urugi (nanone rwitwa valve izamuka).Mubisanzwe hariho urudodo rwa trapezoidal kuri lift, kandi unyuze mubitaka hejuru ya valve hamwe nuyoboye umurongo wo kuyobora kumubiri wa valve, icyerekezo kizunguruka gihinduka umurongo ugororotse, nukuvuga, torque ikora irahinduka mu gikorwa.

Iyo valve ifunguye, iyo uburebure bwo kuzamura isahani y irembo bingana ninshuro 1: 1 z'umurambararo wa valve, inzira y'amazi irakinguwe rwose, ariko uyu mwanya ntushobora gukurikiranwa mugihe ukora.Mu mikoreshereze nyayo, apex ya stem stem ikoreshwa nkikimenyetso, ni ukuvuga, umwanya aho igiti cya valve kitimuka gifatwa nkumwanya wuzuye ufunguye.Kugirango usuzume ibintu bifunga bitewe nubushyuhe bwubushyuhe, mubisanzwe ufunguye kumwanya wo hejuru, hanyuma usubire inyuma 1 / 2-1, nkumwanya wuzuye wa valve.Kubwibyo, imyanya yuzuye ya valve igenwa nu mwanya w irembo (ni ukuvuga inkoni).

Mu marembo amwe n'amwe, ibiti by'uruti bishyirwa ku isahani y'irembo, kandi kuzunguruka kw'uruziga rw'intoki bituma igiti cya valve kizunguruka, kandi icyapa cy'irembo kikazamurwa.Ubu bwoko bwa valve bwitwa rotary stem gate gate valve cyangwa irembo ryijimye ryijimye.
