Ibinyugunyugu bihamyenubwoko bukoreshwa cyane bwikinyugunyugu mu miyoboro yinganda. Bakoresha ibikoresho byoroshye nka reberi nkubuso bwa kashe, bashingiye "kwihanganira ibintu" na "compression structure" kugirango bagere kumikorere.
Iyi ngingo ntabwo yerekana gusa imiterere, imikoreshereze, nibikoresho, ahubwo inabisesengura kuva mubumenyi rusange kugeza kuri logique yimbitse.
1. Gusobanukirwa Byibanze Byibinyugunyugu Bikomeye (Ibisobanuro muri make)
1.1 Imiterere shingiro
Umubiri:Mubisanzwe ubwoko bwa wafer, ubwoko bwa lug, cyangwa ubwoko bwa flanged.
Valve Disc:Isahani izengurutsa icyuma cya reberi iyo ifunze kugirango ikore kashe.
Intebe ya Valve:Ikozwe mubikoresho byoroshye nka NBR / EPDM / PTFE / Rubber Line, ikora ifatanije na disiki ya valve.
Igiti cya Valve:Ahanini ikoresha igishushanyo kimwe cyangwa igishushanyo mbonera.
Umukoresha:Koresha, ibikoresho byinyo, amashanyarazi, pneumatike, nibindi
1.2 Ibiranga rusange
Urwego rwo gufunga rusanzwe rugera kuri zeru.
Igiciro gito kandi kigari cya porogaramu.
Ahanini ikoreshwa muri sisitemu yo hasi yumuvuduko nkamazi, ubukonje, HVAC, ninganda zikora imiti yoroheje.
2. Ibitekerezo bitari byo kubyerekeye ibinyugunyugu byikinyugunyugu
2.1 Intangiriro yo gufunga ni reberi
Abantu benshi bizera: "Intebe zihamye zishingiye ku rebero ishobora gushyirwaho kashe."
Intego nyayo yo gushiraho ikimenyetso ni:
Umubiri wumubiri + valve stem hagati yintera + ububiko bwa disiki yububiko + uburyo bwo gushyiramo intebe
Twese hamwe mukore "zone igenzurwa".
Muri make:
Rubber ntishobora kuba irekuye cyangwa ifunze cyane; ishingiye kuri "kashe ya compression zone" igenzurwa no gutunganya neza.
Kuki ibi ari ngombwa?
Gucomeka bidahagije: Valve irekura iyo ifunze.
Kwikuramo gukabije: Umuhengeri mwinshi cyane, gusaza imburagihe za rubber.
2.2 Ese imiterere ya disiki irushijeho kuba nziza ikoresha ingufu?
Ibisanzwe: Disiki ya valve irashobora kugabanya igihombo.
Ibi ni ukuri ukurikije inyigisho ya "fluid mechanics", ariko ntabwo ikoreshwa muburyo bukoreshwa bwa nyaburanga Ikinyugunyugu.
Impamvu:
Inkomoko nyamukuru yo gutakaza umuvuduko mukibaya kinyugunyugu ntabwo imiterere ya disiki ya valve, ahubwo "ingaruka ya micro-umuyoboro wa tunnel" iterwa no kugabanuka kwa reberi yintebe. Disiki ya valve kuba inanutse cyane irashobora kunanirwa gutanga igitutu gihagije cyo guhuza, birashoboka ko biganisha kumurongo udafunze kandi utemba.
Disiki yoroheje irashobora gutera ingingo zikarishye kuri reberi, bikagabanya igihe cyayo.
Kubwibyo, igishushanyo mbonera cyikinyugunyugu cyicaye cyoroshye gishyira imbere "gushiraho umurongo uhamye" kuruta gutondeka.
2.3 Ibinyugunyugu byicaye byoroheje byoroheje bifite imiterere yo hagati
Bikunze kuvugwa kumurongo ko ibinyugunyugu byikinyugunyugu bigomba gukoresha kashe ikomeye.
Ariko, uburambe bwubuhanga-bwisi bwerekana ko:
Kabiri eccentricité itezimbere cyane ubuzima bwikinyugunyugu kinyugunyugu.
Impamvu:
Double eccentricity: Disiki ya valve ihuza gusa na reberi mugihe cya 2-3 ° yanyuma yo gufunga, bikagabanya cyane guterana.
Umuyoboro muto, biganisha ku guhitamo ibikorwa byubukungu.
2.4 Icyifuzo cyibanze ku cyicaro ni "izina ryibintu"*
Abakoresha benshi bibanda gusa:
EPDM
NBR
Viton (FKM)
Ariko igifite ingaruka mubuzima bwose ni:
2.4.1 Gukomera ku nkombe:
Kurugero, Inkombe Gukomera kwa EPDM ntabwo ari ikibazo cy "icyiza cyiza." Mubisanzwe, 65-75 nuburyo bwiza bwo kuringaniza, kugera kuri zeru kumeneka kumuvuduko muke (PN10-16).
Biroroshye cyane: Umuvuduko muke ariko ushwanyaguritse byoroshye. Mugihe cyumuvuduko ukabije (> 2 MPa) cyangwa ibidukikije bidurumbanye, reberi yoroshye iragabanuka cyane, itera guhindagurika. Byongeye kandi, ubushyuhe bwo hejuru (> 80 ° C) burushijeho koroshya reberi.
Birakomeye cyane: Biragoye gufunga, cyane cyane muri sisitemu yumuvuduko ukabije (<1 MPa), aho reberi idashobora guhagarikwa bihagije kugirango ikore intera yumuyaga, biganisha kuri micro-leakage.
2.4.2 Ubushyuhe bwa Vulcanisation nigihe cyo gukiza
Ubushyuhe bwa Vulcanisation hamwe nigihe cyo gukiza bigenzura guhuza imiyoboro ya rebero ya molekile, bigira ingaruka itaziguye kumiterere yimiterere y'urusobekerane no gukora igihe kirekire. Urutonde rusanzwe ni 140-160 ° C, iminota 30-60. Ubushyuhe bukabije cyangwa buke cyane butera gukira kutaringaniye no gusaza byihuse. Isosiyete yacu muri rusange ikoresha ibirunga byinshi (mbere yo gukira kuri 140 ° C, ikurikirwa no gukira kuri 150 ° C). 2.4.3
Gushira hamwe bivuga igipimo cyo guhindura ibintu burundu reberi ihura nimpungenge zihoraho (mubisanzwe 25% -50% kwikuramo, bipimishije kuri 70 ° C / 22h, ASTM D395) kandi ntibishobora gukira neza. Agaciro keza kuri compression yashizweho ni <20%. Agaciro n "" icyuho "cyo gufunga igihe kirekire cya valve; umuvuduko muremure muremure biganisha ku cyuho gihoraho, ugakora ingingo ziva.
2.4.4
A. Imbaraga za Tensile (mubisanzwe> 10 MPa, ASTM D412) nimpagarara nini cyane reberi ishobora kwihanganira mbere yo kuvunika, kandi ni ingenzi cyane mukurwanya kwambara no kurira kwintebe ya valve. Ibikoresho bya reberi hamwe na karubone yumukara igena imbaraga zingana zintebe ya valve.
Mubibinyugunyugu, birwanya kogosha kuruhande rwa disiki ya valve n'ingaruka zamazi.
2.4.5 Akaga gakomeye kihishe kinyugunyugu ni ukumeneka.
Mu mpanuka zubwubatsi, kumeneka ntabwo arikibazo kinini, ahubwo ni kwiyongera kwa torque.
Igitera rwose kunanirwa na sisitemu ni:
Kwiyongera gutunguranye muri torque y ibikoresho byangiza ibyangiritse → gukora ingendo → valve jamming
Kuki itara ryiyongera gitunguranye?
- Kwiyongera k'ubushyuhe bwo hejuru bwintebe ya valve
- Kwinjiza amazi no kwagura reberi (cyane cyane EPDM yo mu rwego rwo hasi)
- Guhindura burundu ka rubber kubera kwikuramo igihe kirekire
- Igishushanyo kidakwiye cyo gutandukanya icyuma cya valve na disiki ya valve
- Intebe ya Valve itavunitse neza nyuma yo gusimburwa
Kubwibyo, "umurongo wa torque" ni ikimenyetso cyingenzi cyane.
2.4.6 Valve yumubiri gutunganya neza ntabwo ari ngombwa.
Abantu benshi bibeshye bemeza ko gufunga ikinyugunyugu cyicaye cyoroshye cyicaye cyane cyane kuri reberi, bityo ibisabwa kugirango imashini ikorwe neza ntabwo ari ndende.
Ibi ni bibi rwose.
Ubusobanuro bwumubiri wa valve bugira ingaruka:
Valve intebe yuburebure → gushiraho ikimenyetso cyo gutandukana, byoroshye gutera kudahuza mugihe cyo gufungura no gufunga.
Kudahuza bidahagije bya groove → gushushanya mugihe cyo kwishyiriraho intebe
Ikosa hagati yintera ya disiki ya valve → yegereye cyane guhuza
2.4.7 Intangiriro ya "reberi yuzuye / PTFE itondekanye ibinyugunyugu" ni disiki ya valve.
Intandaro ya reberi yuzuye cyangwa PTFE itondekanye ntabwo ari "kugira ahantu hanini bigaragara ko irwanya ruswa," ahubwo ni ukubuza uburyo bwo kwinjira mu miyoboro iciriritse imbere yumubiri wa valve. Ibibazo byinshi hamwe nibinyugunyugu bihendutse ntibiterwa nubwiza bwa reberi, ahubwo:
"Icyuho kimeze nk'umugozi" ku ihuriro ry'intebe ya valve n'umubiri ntabwo byakemuwe neza.
Isuri y'amazi maremare → microcracks → rubber blisting and bulging
Intambwe yanyuma ni ukunanirwa kwintebe yintebe.
3. Kuki Ikinyugunyugu Kinyugunyugu gikoreshwa kwisi yose?
Usibye igiciro gito, impamvu eshatu zimbitse ni:
3.1. Kwihanganira amakosa menshi cyane
Ugereranije n'ikidodo c'icyuma, kashe ya reberi, kubera ubuhanga bworoshye cyane, ifite kwihanganira gukomeye gutandukana no guhindura ibintu.
Ndetse n'amakosa yo gutunganya imiyoboro, gutandukana kwa flange, hamwe no guhangayikishwa na bolt bitwarwa na elastique ya reberi (birumvikana ko ibi ari bike kandi bitifuzwa, kandi bizatera ibyangiritse kumuyoboro na valve mugihe kirekire).
3.2. Guhuza neza na sisitemu ihindagurika
Ikirangantego cya reberi ntabwo "gisenyutse" nkikimenyetso cyicyuma; bahita bishyura umurongo wa kashe mugihe ihindagurika ryumuvuduko.
3.3. Ikiguzi cyo hasi yubuzima bwose
Ibinyugunyugu bifunze-bifunze cyane biraramba, ariko ikiguzi nigikorwa cyo hejuru.
Mugereranije, igiciro rusange cyogushora no kubungabunga ibiciro bya Resilient Butterfly Valves nubukungu.
4. Umwanzuro
Agaciro kaIkinyugunyugu Kinyugunyuguntabwo ari "kashe yoroheje"
Ibinyugunyugu byoroheje bifunze neza bisa nkibintu byoroshye, ariko mubyukuri ibicuruzwa byiza bishyigikiwe na tekinoroji yo mu rwego rwo hejuru, harimo:
Igishushanyo mbonera cya zone yogushushanya
Kugenzura imikorere ya reberi
Guhuza geometrike yumubiri wa valve nigiti
Kwemeza intebe yo guterana
Ubuyobozi bwa Torque
Kwipimisha ubuzima
Ibi nibintu byingenzi byerekana ubuziranenge, ntabwo "izina ryibintu" n "imiterere yimiterere".
