Ibikoresho by'ibice by'ingenzi bya valve bigomba kubanza gusuzuma imiterere yumubiri (ubushyuhe, umuvuduko) hamwe nimiti ya chimique (korosivite) yuburyo bukora.Muri icyo gihe, birakenewe kandi kumenya isuku yikigereranyo (niba hari ibice bikomeye).Byongeye kandi, amabwiriza ajyanye n’ibisabwa bya leta n’ishami ry’abakoresha nabyo byoherezwa.
Ubwoko bwinshi bwibikoresho burashobora kuzuza serivisi zisabwa na valve mubihe bitandukanye byakazi.Nyamara, ubuzima bwa serivise yubukungu cyane nibikorwa byiza bya valve birashobora kuboneka muguhitamo neza kandi gushyira mu gaciro ibikoresho bya valve.
Ibikoresho bisanzwe byumubiri wa valve
1. Icyuma cyumucanga wicyuma gikoreshwa cyane mubikorwa bitandukanye byinganda kubera igiciro cyacyo gito kandi kigakoreshwa.Ubusanzwe zikoreshwa mubijyanye n’amazi, amavuta, amavuta na gaze nkibikoresho, kandi bikoreshwa cyane mu nganda z’imiti, gucapa no gusiga amarangi, amavuta, imyenda n’ibindi bicuruzwa byinshi mu nganda bidafite ingaruka nke cyangwa zitagira ingaruka ku ihumana ry’icyuma.
Irakoreshwa kumuvuduko muke ufite ubushyuhe bwakazi bwa - 15 ~ 200 ℃ hamwe numuvuduko wizina wa PN ≤ 1.6MPa.
ishusho
2. Icyuma cyumukara cyoroshye gishobora gukoreshwa kumashanyarazi yo hagati na make hamwe nubushyuhe bwakazi hagati ya - 15 ~ 300 ℃ numuvuduko wizina PN ≤ 2.5MPa.
Ibitangazamakuru byakoreshwa ni amazi, amazi yo mu nyanja, gaze, ammonia, nibindi
3. Icyuma cyitwa Nodular cyuma Nodular cast nicyuma cyicyuma, ni ubwoko bwicyuma.Igishushanyo cya flake mumyenda yicyuma gisimburwa na nodular grafite cyangwa globular grafite.Guhindura imiterere yimbere yiki cyuma bituma imiterere yubukanishi iruta icyuma gisanzwe cyumukara, kandi ntabwo yangiza indi mico.Kubwibyo, indanga zikoze mucyuma zidafite imbaraga zifite umuvuduko mwinshi wa serivisi kuruta iyakozwe nicyuma.Irakoreshwa kumashanyarazi yo hagati na make hamwe nubushyuhe bwakazi bwa - 30 ~ 350 ℃ hamwe numuvuduko wizina wa PN ≤ 4.0MPa.
Uburyo bukoreshwa ni amazi, amazi yo mu nyanja, umwuka, umwuka, gaze, amavuta, nibindi.
4. Ibyuma bya karubone (WCA, WCB, WCC) byabanje gukora ibyuma bikozwe mubyuma kugirango bikemure umusaruro urenze ubushobozi bwumuringa wibyuma hamwe numuringa wumuringa.Nyamara, kubera imikorere myiza ya serivise ya karubone hamwe no guhangana cyane ningutu ziterwa no kwaguka kwinshi, imitwaro yingaruka no guhindura imiyoboro, uburyo bwabo bwo gukoresha bwagutse, mubisanzwe harimo nakazi k’ibikoresho by’ibyuma bikozwe mu cyuma hamwe n’umuringa.
Irakoreshwa kumurongo wo hejuru kandi mwinshi hamwe nubushyuhe bwo gukora bwa - 29 ~ 425 ℃.Ubushyuhe bwa 16Mn na 30Mn buri hagati ya - 40 ~ 400 ℃, bukoreshwa kenshi mu gusimbuza ASTM A105.Uburyo bukoreshwa ni ibyuka byuzuye hamwe nubushyuhe bukabije.Ibikomoka kuri peteroli yo hejuru kandi ntoya, gaze ya lisukari, umwuka ucanye, amazi, gaze gasanzwe, nibindi
5. Ubushyuhe buke bwa karubone (LCB) Ubushyuhe buke bwa karubone nicyuma gito cya nikel alloy irashobora gukoreshwa mubushyuhe buri munsi ya zeru, ariko ntibishobora kwaguka mukarere ka kirogenike.Imyanda ikozwe muri ibyo bikoresho irakwiriye kubitangazamakuru bikurikira, nk'amazi yo mu nyanja, dioxyde de carbone, acetylene, propylene na Ethylene.
Irakoreshwa mubushyuhe bwo hasi hamwe nubushyuhe bwo gukora hagati - 46 ~ 345 ℃.
6. Imyanda ikozwe mubyuma bito (WC6, WC9) hamwe nicyuma gike cyane (nkicyuma cya karubone molybdenum nicyuma cya chromium molybdenum) irashobora gukoreshwa muburyo bwinshi bukora, harimo amavuta yuzuye kandi ashyushye, amavuta akonje nubushyuhe, gaze gasanzwe n'umwuka.Ubushyuhe bwo gukora bwa karuboni yicyuma irashobora kuba 500 ℃, naho iy'icyuma giciriritse gishobora kuba hejuru ya 600 ℃.Ku bushyuhe bwinshi, imiterere yubukanishi bwibyuma bito cyane birenze ibyuma bya karubone.
Ubushyuhe bwo hejuru hamwe n’umuvuduko mwinshi ukoreshwa muburyo butangirika hamwe nubushyuhe bwo gukora hagati - 29 ~ 595 ℃;C5 na C12 birakoreshwa mubushyuhe bwo hejuru hamwe numuvuduko mwinshi wibikoresho byangirika hamwe nubushyuhe bwo gukora hagati ya - 29 na 650 ℃.
7. Ibyuma bya Austenitike bitagira umuyonga ibyuma bya Austenitike birimo chromium hafi 18% na nikel 8%.18-8 ibyuma bya austenitike bitagira umuyonga akenshi bikoreshwa nkumubiri wa valve nibikoresho bya bonnet munsi yubushyuhe buke kandi buke hamwe nubushuhe bukomeye.Ongeramo molybdenum kuri matrike ya 18-8 idafite ibyuma no kongera nikel nkeya bizongera cyane kurwanya ruswa.Imyanda ikozwe muri iki cyuma irashobora gukoreshwa cyane mu nganda z’imiti, nko gutanga aside aside, aside nitric, alkali, byakuya, ibiryo, umutobe wimbuto, aside karubone, amavuta yo kwisiga hamwe nibindi bicuruzwa byinshi bya shimi.
Kugirango ushyire mubushyuhe bwo hejuru no kurushaho guhindura ibintu, niobium yongewe kumyuma idafite umwanda, izwi nka 18-10-Nb.Ubushuhe burashobora kuba 800 ℃.
Icyuma cya Austenitike kitagira umuyonga gikoreshwa mubushyuhe buke cyane kandi ntikizacika intege, bityo valve ikozwe muribi bikoresho (nka 18-8 na 18-10-3Mo) irakwiriye cyane gukora mubushyuhe buke.Kurugero, itwara gaze yamazi, nka gaze karemano, biyogazi, ogisijeni na azote.
Irakoreshwa kuri valve ifite uburyo bubora hamwe nubushyuhe bwo gukora hagati - 196 ~ 600 ℃.Icyuma cya Austenitike nicyuma nacyo cyiza cyo hasi yubushyuhe.

8. Plastike nubutaka byombi nibikoresho bitari ibyuma.Ikintu kinini kiranga ibikoresho bitarimo ibyuma ni imbaraga zikomeye zo kurwanya ruswa, ndetse zikaba zifite ibyiza ibyuma byuma bidashobora kugira.Mubisanzwe birakoreshwa mubitangazamakuru byangirika bifite umuvuduko wizina PN ≤ 1.6MPa hamwe nubushyuhe bwakazi butarenga 60 and, kandi idafite uburozi SINGLE UNION BALL VALVE nayo ikoreshwa mubikorwa byo gutanga amazi.Ibikoresho by'ibice by'ingenzi bya valve bigomba kubanza gusuzuma imiterere yumubiri (ubushyuhe, umuvuduko) hamwe nimiti ya chimique (korosivite) yuburyo bukora.Muri icyo gihe, birakenewe kandi kumenya isuku yikigereranyo (niba hari ibice bikomeye).Byongeye kandi, amabwiriza ajyanye n’ibisabwa bya leta n’ishami ry’abakoresha nabyo byoherezwa.
Ubwoko bwinshi bwibikoresho burashobora kuzuza serivisi zisabwa na valve mubihe bitandukanye byakazi.Nyamara, ubuzima bwa serivise yubukungu cyane nibikorwa byiza bya valve birashobora kuboneka muguhitamo neza kandi gushyira mu gaciro ibikoresho bya valve.
