Mugihe uhitamo valve iburyo bwa sisitemu yinganda, ubuhinzi, cyangwa ubucuruzi, gusobanukirwa itandukaniro riri hagatilug ibinyugunyugunakabiri flange ikinyugunyuguni ngombwa. Iyi mibande yombi ikoreshwa cyane mugutunganya amazi, gutunganya imiti, HVAC, ninganda za peteroli na gaze kubera igishushanyo mbonera cyayo, gukora neza, no kugenzura neza imigezi. Nyamara, igishushanyo mbonera cyabo, uburyo bwo kwishyiriraho, hamwe nibisabwa biratandukanye, bigatuma buri kimwe gikwiranye nibihe byihariye. Iyi ngingo iragaragaza itandukaniro ryingenzi, ibyiza, ibibi, hamwe nogukoresha lug na kabiri ya flange ikinyugunyugu kugirango uyobore inzira yawe yo gufata ibyemezo.
1. Lug Butterfly Valve: Igishushanyo nibiranga
Ibinyugunyugu by'ibinyugunyugu birangwa no gushiramo urudodo, cyangwa "lugs", ku mubiri wa valve, ibyo bikaba byemerera guhindagurika kuri flanges. Igishushanyo gikoresha ibice bibiri byigenga bitagira utubuto, nkurudodo rwimigozi rwihishwa. Iboneza nkibi nibyiza kumpera yumurongo wa porogaramu, aho uruhande rumwe rwumuyoboro rushobora guhagarikwa bitagize ingaruka kurundi.
Ibyingenzi Byingenzi bya Lug Ikinyugunyugu
.
- Igishushanyo mbonera: Ibiremereye kandi bigufi muburebure, lug valve ibika umwanya, byuzuye kuri sisitemu ifite icyumba gito.
- Urujya n'uruza rw'ibice bibiri: Byoroheje bifunze lug valve bifasha gutembera mubyerekezo byombi, bitanga byinshi.
- Kubungabunga byoroshye: Ibikoresho bya lug bituma uruhande rumwe rwumuyoboro ruvaho kugirango rukorwe nta ngaruka kurundi.
- Igipimo cyumuvuduko: Mubisanzwe bikwiranye na progaramu yo hasi-yohasi, nubwo igipimo cyumuvuduko gishobora kugabanuka kumurongo wanyuma wumurongo.
- Guhindura Ibikoresho: Biboneka mubikoresho nka fer ductile, WCB, cyangwa ibyuma bidafite ingese, hamwe nintebe zicaro nka EPDM cyangwa PTFE yo kurwanya imiti.
2. Valve Ikinyugunyugu cya Flange ebyiri: Igishushanyo nibiranga
Ibibabi byikinyugunyugu bibiri biranga flanges ihuriweho kumpande zombi zumubiri wa valve, ihujwe neza na flanges ya pipe. Igishushanyo cyemeza ko kidashobora guhuza, bigatuma gikwiranye n’umuvuduko mwinshi hamwe na diameter nini. Kubaka kwayo gukomeye birwanya imbaraga zikomeye.
Ibyingenzi byingenzi biranga ikinyugunyugu kabiri
- Imikorere ihuriweho: Flanges kumpande zombi ihuza imiyoboro ya flanges ikoresheje bolts, ikemeza neza.
- Imiterere ikomeye: Yakozwe mubikoresho biramba nka WCB, ibyuma byangiza, cyangwa ibyuma bidafite ingese.
- Ikidodo cyiza: Igishushanyo cya flange cyerekana kashe ikomeye, kugabanya ingaruka zishobora kumeneka mubikorwa bikomeye.
- Urujya n'uruza rw'ibice: Nka lug valve, ibyuma bibiri bya flange bifasha gutembera mubyerekezo byombi.
- Diameter Nini: Yakira diameter nini ugereranije na lug valve.
3. Lug Butterfly Valve na Double Flange Ikinyugunyugu
Guhitamo neza, gusobanukirwa itandukaniro ryingenzi hagati ya lug na kabiri ya flange ikinyugunyugu ni ngombwa. Hano haribigereranyo birambuye kubintu bikomeye:
3.1 Ibiranga rusange
- Kwiyubaka byoroshye: Byombi byemerera uruhande rumwe rwumuyoboro guhagarikwa bitagize ingaruka kurundi, nibyiza kuri sisitemu isaba kubungabungwa kenshi cyangwa kwigunga.
- Igiciro Ugereranije na Wafer Valves: Bitewe n'imigozi ifatanye cyangwa flanges ebyiri, byombi bihenze kuruta wafer.
- Ibiranga Bisangiwe:
.
- Ibikoresho bitandukanye: Byombi birashobora gukorwa mubikoresho bisa nkibyuma bya karubone, ibyuma byangiza, cyangwa ibyuma bidafite ingese, hamwe nintebe zicaro (urugero, EPDM cyangwa PTFE) zijyanye n'amazi nk'amazi, imiti, cyangwa gaze.
3.2 Itandukaniro ryingenzi
3.2.1 Uburyo bwo Kwishyiriraho
- Lug Butterfly Valve: Koresha umutwe umwe kugirango uhuze imiyoboro ya flanges. Imigozi ifatanye yemerera ibice bibiri bya bolts kugirango irinde valve yigenga nta mbuto, ishyigikira impera yumurongo wa serivisi no kuyitaho.
- Ikinyugunyugu cya kabiri cya Flange: Ikiranga flanges ihuriweho kumpande zombi, bisaba guhuza imiyoboro ya pipe na bolting. Ibi byemeza guhuza gukomeye ariko bigoye kubungabunga.
3.2.2
- Lug Butterfly Valve: Itanga ibintu byoroshye guhinduka, kuko uruhande rumwe rushobora guhagarikwa bitagize ingaruka kurundi, nibyiza kuri sisitemu ikenera kubungabungwa kenshi cyangwa kuyisimbuza.
- Double Flange Butterfly Valve: Irasaba guhuza no guhinduranya kumpande zombi, gukora installation no kuyikuraho bitwara igihe. Itanga uburyo bworoshye bwo kubungabunga ariko ihuza umutekano.
3.2.3
- Lug Butterfly Valve: Mubisanzwe biva kuri DN50 kugeza DN600.Umuyoboro umwebirashobora kuba ubundi buryo bwa sisitemu yagabanijwe.
- Ikinyugunyugu cya kabiri cya Flange: Ikinyuranyo kuva DN50 kugeza DN1800. Kuri diameter nini, ibisubizo byabigenewe birahari bisabwe.
3.2.4 Igiciro nuburemere
- Lug Butterfly Valve: Igiciro cyinshi bitewe nigishushanyo cyayo cyoroheje, kugabanya amafaranga yo kwishyiriraho.
- Double Flange Butterfly Valve: Iremereye kandi ihenze cyane kubera flanges ihuriweho hamwe nibindi bikoresho. Kinini-diameter nini ya flange ya valve irashobora gusaba inkunga yinyongera kubera uburemere bwayo.
3.2.5 Kubungabunga no Gusenya
- Lug Butterfly Valve: Biroroshye gusenya no kubungabunga, kuko uruhande rumwe rushobora gukurwaho rutagize ingaruka kurundi.
- Double Flange Butterfly Valve: Imirimo myinshi isaba akazi gusenya bitewe na bolts nyinshi nibisabwa guhuza neza.
4. Umwanzuro
Guhitamo hagati yoroheje-ifunzelug ibinyugunyuguna akabiri flange ikinyugunyugubiterwa na sisitemu yihariye ikeneye. Amavuta yikinyugunyugu aruta ayandi muri porogaramu zisaba kubungabungwa kenshi no kwishyiriraho. Kabiri ikinyugunyugu kinyugunyugu, hamwe no gufunga gukomeye, birakwiriye cyane kumiyoboro minini ya diameter hamwe nibisabwa bikomeye. Mugusuzuma ibintu nkigitutu, kubungabunga, umwanya, na bije, urashobora guhitamo valve itunganya imikorere nigiciro-cyiza.
