Guhagarika valve ikoreshwa cyane mugutunganya no guhagarika amazi atembera mumiyoboro.Bitandukanye na valve nkimipira yumupira hamwe namarembo y amarembo kuberako yabugenewe kugirango igenzure neza amazi kandi ntabwo bigarukira kuri serivisi zifunga.Impamvu ituma valve ihagarara yitwa cyane nuko igishushanyo cya kera cyerekana umubiri runaka kandi gishobora kugabanywamo ibice bibiri, bitandukanijwe na ekwateri, aho imigezi ihindura icyerekezo.Ibintu byimbere byimbere yintebe yo gufunga mubisanzwe ntabwo ari serefegitura (urugero, imipira yumupira) ariko mubisanzwe ni planari, igice cyisi, cyangwa icyuma gikozwe.Umubumbe w'isi ugabanya umuvuduko w'amazi cyane iyo ufunguye kuruta irembo cyangwa imipira, bigatuma umuvuduko mwinshi ugabanuka.Umubumbe wa globe ufite ibice bitatu byingenzi bigize umubiri, bimwe muribi bikoreshwa mukugabanya umuvuduko wumuvuduko unyuze muri valve.Kumakuru kubindi bikoresho, nyamuneka reba Igitabo cyabaguzi bacu.

Igishushanyo mbonera

Guhagarika valve igizwe nibice bitatu byingenzi:valve umubiri nintebe, disiki ya valve nigiti, gupakira na bonnet.Mubikorwa, uzenguruke uruti rudodo ukoresheje intoki cyangwa intoki kugirango uzamure disiki ya valve kuva kuntebe ya valve.Amazi anyura muri valve afite inzira ya Z kugirango inzira ishobore kuvugana numutwe wa disiki ya valve.Ibi bitandukanye na valve yumuryango aho amazi atembera kumarembo.Iboneza rimwe na rimwe bisobanurwa nkumubiri wa Z umeze nka Z cyangwa umubiri wa T.Kwinjira no gusohoka byahujwe hamwe.

Ibindi bishushanyo birimo inguni na Y-shusho.Mu mpagarike ihagarika valve, isohoka ni 90 ° kuva aho winjirira, kandi amazi atembera munzira ya L.Muburyo bwa Y cyangwa Y-imiterere yimibiri yumubiri, uruti rwa valve rwinjira mumubiri wa valve kuri 45 °, mugihe ibyinjira nibisohoka biguma kumurongo, kimwe no muburyo butatu.Kurwanya ingero zinguni gutemba ni ntoya kurenza iyishusho ya T, kandi kurwanya ishusho ya Y ni nto.Inzira eshatu zinzira nizisanzwe muburyo butatu.

Disiki yo gufunga isanzwe ikozwe kugirango ihuze intebe ya valve, ariko disiki iringaniye irashobora kandi gukoreshwa.Iyo valve ifunguye gato, amazi atembera neza hafi ya disiki, no gukwirakwiza imyenda ku ntebe ya valve na disiki.Kubwibyo, valve ikora neza mugihe umuvuduko wagabanutse.Mubisanzwe, icyerekezo gitemba kigana kuruhande rwa valve kuruhande rwa valve, ariko mubushyuhe bwubushyuhe bwo hejuru (parike), iyo umubiri wa valve ukonje kandi ugasezerana, imigezi akenshi irahindukira kugirango disiki ya valve ifunzwe neza.Umuyoboro urashobora guhindura icyerekezo cyogukoresha kugirango ukoreshe igitutu kugirango ufashe gufunga (gutembera hejuru ya disiki) cyangwa gufungura (gutemba munsi ya disiki), bityo bigatuma valve inanirwa gufunga cyangwa kunanirwa gufungura.

Ikidodo cyangwa kasheni Byerekanwe Kuri Intebe Binyuze mu kato kugira ngo hamenyekane neza, cyane cyane mu muvuduko ukabije wa porogaramu.Ibishushanyo bimwe bikoresha intebe ya valve, kandi kashe kuruhande rwa valve inkoni ya disiki ikanda ku ntebe ya valve kugirango irekure igitutu cyo gupakira iyo valve ifunguye neza.

Ukurikije igishushanyo mbonera cya kashe, guhagarika valve birashobora gukingurwa byihuse ninzira nyinshi zuruti rwumubyimba kugirango utangire vuba (cyangwa ufunzwe kugirango uhagarike gutemba), cyangwa buhoro buhoro ufungurwa buhoro buhoro nizunguruka ryinshi ryikibaho kugirango ubyare byinshi gutembera gutembera muri valve.Nubwo amacomeka rimwe na rimwe akoreshwa nkibintu bifunga kashe, ntibigomba kwitiranywa nugucomeka kumashanyarazi, aribikoresho byigihembwe, bisa numupira wumupira, ukoresha ibyuma aho gukoresha imipira kugirango uhagarare kandi utangire gutemba.

Porogaramu

Guhagarika valve bikoreshwa muguhagarika no kugenzura ibihingwa bitunganya amazi mabi, amashanyarazi ninganda zitunganya.Zikoreshwa mu miyoboro ya parike, imiyoboro ikonjesha, sisitemu yo gusiga amavuta, nibindi, aho kugenzura umubare wamazi anyura mumibande bigira uruhare runini.

Guhitamo ibikoresho byumubiri wa valve mubusanzwe bikozwe mubyuma cyangwa umuringa / umuringa mugukoresha ingufu nkeya, hamwe nibyuma bya karubone cyangwa ibyuma bidafite ingese mumuvuduko mwinshi nubushyuhe.Ibikoresho byerekanwe kumubiri wa valve mubisanzwe birimo ibice byumuvuduko, kandi "trim" bivuga ibice bitari umubiri wa valve, harimo intebe ya valve, disiki nigiti.Ingano nini igenwa nicyiciro cyingutu cya ASME, kandi ibisanzwe bisanzwe cyangwa gusudira byateganijwe.Kuringaniza umubumbe wa globe bisaba imbaraga nyinshi kuruta gupima ubundi bwoko bwa valve kuko kugabanuka k'umuvuduko kuruhande bishobora kuba ikibazo.

Kuzamuka kw'ibiti ni byo bikunze kugaragara mu guhagarara, ariko ibiti bitazamuka bishobora no kuboneka.Bonnet isanzwe ihindagurika kandi irashobora gukurwaho byoroshye mugihe cyo kugenzura imbere ya valve.Intebe ya valve na disiki biroroshye kuyisimbuza.

Hagarika indangagaciromubisanzwe byikora ukoresheje piston pneumatike cyangwa diaphragm ikora, ikora neza kumurongo wa valve kugirango yimure disiki mumwanya.Piston / diaphragm irashobora kuba impeshyi ibogamye kugirango ifungure cyangwa ifunge valve nyuma yo gutakaza umuvuduko wumwuka.Amashanyarazi azunguruka nayo arakoreshwa.
