Valve z'ibinyugunyugu zikomerani ubwoko bwa valve y'ibinyugunyugu ikoreshwa cyane mu miyoboro y'inganda. Bakoresha ibikoresho bya elastic nka rubber nk'ubuso bwo gufunga, bishingikiriza ku "bushobozi bw'ibikoresho" na "gukanda imiterere" kugira ngo bagere ku musaruro wo gufunga.
Iyi nkuru ntabwo isobanura gusa imiterere, imikoreshereze, n'ibikoresho, ahubwo inasesengura kuva ku bumenyi rusange kugeza ku bwenge bwimbitse.
1. Ubumenyi bw'ibanze ku miterere y'udupira tw'ibinyugunyugu twifata neza (Ibisobanuro bigufi)
1.1 Imiterere y'ibanze
Umubiri w'ingufu:Ubusanzwe ubwoko bwa wafer, ubwoko bwa lug, cyangwa ubwoko bwa flange.
Disiki ya Valve:Isahani y'icyuma izunguruka ikandagira intebe ya rubber iyo ifunze kugira ngo ikoremo agapfundikizo.
Intebe ya Valve:Yakozwe mu bikoresho bya elastic nka NBR/EPDM/PTFE/Rubber Lined, ikorana na disiki ya valve.
Igiti cya Valve:Akenshi ikoresha igishushanyo cy'umugozi umwe cyangwa ibiri.
Umukozi ushinzwe gukora:Igikoresho cyo gufataho, ibikoresho byo mu bwoko bwa worm, amashanyarazi, umwuka, nibindi.
1.2 Ibintu Bisanzwe
Ubusanzwe urwego rwo gufunga nta gusohoka kw'amazi.
Igiciro gito n'uburyo butandukanye bwo gukoresha.
Ikoreshwa cyane mu buryo bw'umuvuduko muto kugeza kuri hagati nko mu mazi, mu byuma bikonjesha, mu byuma bitanga ubushyuhe, ndetse no mu nganda zikora imiti yoroheje.
2. Ibitekerezo bitari byo ku byerekeye Valves z'ibinyugunyugu zihamye
2.1 Ishingiro ry'ipfundikizo ni ukwihangana kwa rubber
Abantu benshi bizera bati: "Intebe zihamye zishingira ku gukomera kwa rabara mu kuzifunga."
Ishingiro nyakuri ry'ugufunga ni:
Umubiri w'imvange + intera iri hagati y'umugongo w'imvange + ubugari bw'imvange + uburyo bwo gushyiramo umwanya w'imvange
Hamwe mukore "agace ko gukanda kagenzurwa".
Mu magambo make:
Rubber ntishobora kuba irekuye cyane cyangwa ifunze cyane; ishingiye ku "gace gashyirwamo ingufu" kagenzurwa n'uburyo bwo gukora neza.
Kuki ibi ari ingenzi cyane?
Gukanda kudahagije: Valve irasohoka iyo ifunze.
Gukanda cyane: Gukomera cyane, gusaza imburagihe.
2.2 Ese imiterere ya disiki yoroshye cyane ikoresha ingufu nke?
Igitekerezo rusange: Disiki za valve zikozwe neza zishobora kugabanya igihombo.
Ibi ni ukuri dukurikije inyigisho ya "fluid mechanics", ariko ntabwo bireba neza ikoreshwa ry’amavalue ya Resilient Butterfly.
Impamvu:
Inkomoko nyamukuru y’igitutu mu tunnel z’ibinyugunyugu si imiterere ya disiki ya valve, ahubwo ni "ingaruka za tunnel za micro-channel" ziterwa no gupfunyika kwa rubber y’intebe ya valve. Disiki ya valve iyo ari nto cyane ishobora kunanirwa gutanga igitutu gihagije, bikaba byatera imiyoboro idakomeza gufunga no kuva.
Disiki ya valve ikozwe mu buryo burambuye ishobora gutera imihangayiko ikomeye kuri rabha, ikagabanya igihe cyo kuyimara.
Kubwibyo, igishushanyo mbonera cy'udupira tw'ibinyugunyugu twicaye neza gishyira imbere "guhagarara k'umurongo ufunga" kuruta kunoza imiterere.
2.3 Utwuma tw'ibinyugunyugu twicaye neza dufite imiterere yo hagati gusa
Bikunze kuvugwa kuri interineti ko uturindantoki tw’ibinyugunyugu tudasanzwe tugomba gukoresha ibyuma bikomeye bifunga.
Ariko, ubunararibonye mu by'ubwubatsi mu isi nyayo bwerekana ko:
Ubushobozi bubiri bwo kwihuza butuma Valves za Resilient Butterfly zigira igihe kirekire cyo kubaho.
Impamvu:
Ubwumvikane bubiri: Disiki ya valve ikorana gusa na rabha mu gihe cy'ubugari bwa 2-3° bwa nyuma bwo gufunga, bigabanya cyane uburyaryate.
Umuvuduko muto w'amashanyarazi, bigatuma habaho guhitamo actuators zihendutse cyane.
2.4 Ikintu cy'ingenzi kigomba kwitabwaho ku ntebe ya rubber ni "izina ry'ibikoresho"*
Abakoresha benshi bibanda gusa kuri:
EPDM
NBR
Viton (FKM)
Ariko ikintu bigira ingaruka ku buzima bw'umuntu ni iki:
2.4.1 Ubukomere bw'inkombe:
Urugero, ubukana bwa EPDM ku nkengero za A ntabwo ari ikibazo cy'uko "iyo yoroshye ari bwo bwiza." Ubusanzwe, 65-75 ni yo ngamba nziza yo kuringaniza, bigatuma hatabaho kuvogera na gato ku muvuduko muke (PN10-16).
Yoroshye cyane: Umuvuduko muke ariko byoroshye gucika. Mu gihe cy'umuvuduko mwinshi (>2 MPa) cyangwa ahantu hahindagurika, umuvuduko woroshye urakandamizwa cyane, bigatuma habaho guhindagurika kw'ingufu. Byongeye kandi, ubushyuhe bwinshi (>80°C) burushaho koroshya umuvuduko.
Gukomera cyane: Kubifunga biragoye, cyane cyane muri sisitemu zifite umuvuduko muto (<1 MPa), aho irangi ridashobora gukandamizwa bihagije kugira ngo rikore ahantu hatagerwa n'umwuka, bigatuma amazi asohoka mu buryo buciriritse.
2.4.2 Ubushyuhe bwa Vulcanization n'igihe cyo kuvura
Ubushyuhe bwa Vulcanization n'igihe cyo gukaraba bigenzura uburyo imiyoboro ya molekile ya rubber ihurirana, bigira ingaruka ku buryo butaziguye ku miterere y'urusobe rw'amazi n'imikorere yarwo mu gihe kirekire. Ingano isanzwe ni 140-160°C, iminota 30-60. Ubushyuhe bwinshi cyane cyangwa buke cyane butuma habaho gukaraba ku buryo butari bumwe no gusaza vuba. Isosiyete yacu muri rusange ikoresha vulcanization y'ibice byinshi (pre-curing kuri 140°C, hagakurikiraho post-curing kuri 150°C). 2.4.3 Itsinda ry'ibikoresho byo gukaraba
Igipimo cyo gukanda bivuze igipimo cy'ihinduka rihoraho rya rubber rikorerwa mu gihe cy'ihungabana rihoraho (ubusanzwe 25%-50% by'ihungabana, ryapimwe kuri 70°C/amasaha 22, ASTM D395) kandi ntirishobora gukira neza. Igipimo cyiza cy'igipimo cyo gukanda ni <20%. Iki gipimo ni "inzitizi" yo gufunga valve igihe kirekire; umuvuduko mwinshi w'igihe kirekire utuma habaho icyuho gihoraho, bigatuma habaho aho amazi asohoka.
2.4.4 Ingufu zo Gufata
A. Ingufu zo gukurura (ubusanzwe >10 MPa, ASTM D412) ni umuvuduko ntarengwa rubber ishobora kwihanganira mbere yo kuvunika, kandi ni ingenzi cyane ku buryo intebe ya valve idashanguka kandi idacika. Ingano ya rubber n'umukara wa karuboni bigena imbaraga zo gukurura rubber.
Mu miyoboro y'ibinyugunyugu, irwanya gucibwa n'inkombe y'ikinyugunyugu cya disiki n'amazi.
2.4.5 Akaga gakomeye cyane k’udupira tw’ibinyugunyugu ni ukuva kw’amazi.
Mu mpanuka z’ubuhanga, amazi asohoka akenshi si cyo kibazo gikomeye, ahubwo ni ukwiyongera kwa torque.
Igitera gutsindwa kwa sisitemu mu by'ukuri ni iki:
Ubwiyongere butunguranye bw'imbaraga zikoreshwa mu gutwika → Kwangirika kw'ibikoresho by'inzoka → Gucika intege kw'actuator → Kugwa kw'ingufu
Kuki imbaraga ziyongera mu buryo butunguranye?
- Kwagura intebe y'agapira k'amashanyarazi mu bushyuhe bwinshi
- Gukurura no kwagura amazi ya rubber (cyane cyane EPDM idakora neza)
- Guhinduka burundu kw'ururabo bitewe no gukandamizwa igihe kirekire
- Igishushanyo mbonera kitari cyiza cy'icyuho kiri hagati y'umugongo wa valve na disiki ya valve
- Intebe ya valve ntiyacitse neza nyuma yo kuyihindura
Bityo rero, "umugozi w'ingufu" ni ikimenyetso cy'ingenzi cyane.
2.4.6 Uburyo bwo gutunganya neza imashini mu gice cy'imashini si ngombwa.
Abantu benshi bibeshya ko gufunga valve z'ibinyugunyugu zoroshye bishingiye ahanini ku rubura, bityo ibisabwa ku buryo bwo gukora neza kw'umubiri wa valve ntabwo biri hejuru.
Ibi ni bibi rwose.
Ubunyangamugayo bw'umubiri wa valve bugira ingaruka kuri ibi bikurikira:
Ubujyakuzimu bw'aho intebe y'ahashyirwa amashanyarazi → Gufunga bigabanya uburyo bwo gufunga, bigatuma habaho kutumvikana nabi mu gihe cyo gufungura no gufunga.
Kudakora neza kw'inkombe y'umuyoboro → gushwanyagurika mu gihe cyo gushyiraho intebe y'abarindazi
Ikosa mu ntera yo hagati ya disiki ya valve → aho ikora cyane
2.4.7 Ishingiro rya "valve z'ibinyugunyugu zikozwe mu rubber/PTFE" ni disiki ya valve.
Ishingiro ry'imiterere yuzuye ya rubber cyangwa PTFE ntabwo ari ukugira "ahantu hanini hasa n'aho hadafatwa n'ingese," ahubwo ni ukubuza icyo gikoresho kwinjira mu miyoboro mito iri imbere mu gice cy'umubiri wa vali. Ibibazo byinshi ku miyoboro ihendutse ya vali z'ibinyugunyugu ntibiterwa n'ubwiza bubi bwa rubber, ahubwo ni:
"Icyuho gisa n'umugozi" kiri aho intebe n'umubiri wa valve bihurira ntabwo gishyirwa neza.
Isuri y'amazi igihe kirekire → uduce duto → uduce duto tw'urubura duhinduka udusebe n'ibibyimba
Intambwe ya nyuma ni ukwangirika kw'intebe ya valve.
3. Kuki Valves za Resilient Butterfly zikoreshwa ku isi yose?
Uretse ikiguzi gito, impamvu eshatu z’ingenzi ni izi:
3.1. Kwihanganira amakosa menshi cyane
Ugereranyije n'udupfundikizo tw'icyuma, udupfundikizo twa rubber, bitewe n'uburyo twazo bworoshye bwo guhindagurika, dufite ubushobozi bwo kwihanganira guhindagurika kw'imitako no kwangirika guke.
Ndetse n'amakosa yo gukora imiyoboro, kunyuranya kw'imigozi, no guhagarara kw'imigozi ku buryo butangana bitwarwa n'ubudahangarwa bw'umugozi (birumvikana ko ibi ari bike kandi ntibikwiye, kandi bizatera kwangirika k'umuyoboro na vali mu gihe kirekire).
3.2. Uburyo bwiza bwo guhuza n'ihindagurika ry'umuvuduko w'umubiri
Ibyuma bifunga imipira ntabwo "bikomeye" nk'iby'icyuma bifunga imipira; bihita byishyura umurongo ufunga iyo umuvuduko uhindagurika.
3.3. Igiciro gito cyane cy'ubuzima bwose
Valve z'ibinyugunyugu zifunze neza ziraramba cyane, ariko ikiguzi n'ikiguzi cy'ibikoresho byo gukurura ni byinshi.
Ugereranije, ishoramari rusange n'ikiguzi cyo kubungabunga Resilient Butterfly Valves birahendutse cyane.
4. Umwanzuro
Agaciro kaValves z'ibinyugunyugu zihamyesi "gufunga byoroshye" gusa
Valve zoroshye zifunze neza zishobora gusa n'aho zoroshye, ariko ibikoresho byiza cyane bishyigikiwe n'uburyo bworoshye bwo gukora ibintu, harimo:
Igishushanyo mbonera cy'agace gakomeye
Imikorere ya rubber igenzurwa
Guhuza imiterere y'umubiri w'agakingirizo n'igitereko
Uburyo bwo guteranya intebe ya valve
Gucunga torque
Ikizamini cy'ubuzima
Ibi ni byo bintu by'ingenzi bigena ubuziranenge, ntabwo ari "izina ry'ibikoresho" n' "imiterere y'isura".
