Valve z'ibinyugunyugu zikora neza cyane (HPBVs) ni iki?

1. Ni iki gikoresho cy'ubururu gitanga umusaruro mwinshi (High Performance Butterfly Valves)

Valve y'ibinyugunyugu ifite imikorere myiza yerekeza ku bwoko bushya bw'ibicuruzwa bya valve y'ibinyugunyugu binoza uburyo valve y'ibinyugunyugu ifunga kandi idashira, yongera ubushyuhe bwinshi n'ubudahangarwa, kandi ikongera ubuzima bwiza bwo kuyikoresha hashingiwe ku mashini zisanzwe za valve (Concentric butterfly valves na triple eccentric butterfly valves) binyuze mu kunoza imiterere n'ibikoresho. Ugereranyije na valve zisanzwe za valve, valve y'ibinyugunyugu ifite imikorere myiza yo kuramba, imbaraga zoroshye zo kuyikoresha, kandi ikora neza mu kuyifunga.

Valve z'ibinyugunyugu zikora neza cyane (HPBVs) zigaragaza iterambere rigezweho ry'imiterere isanzwe y'valve z'ibinyugunyugu. Zakozwe mu rwego rwo kuzifunga neza, kuramba no kuzigenzura mu bikorwa by'ingenzi, zifite imiterere ya disiki ya offset (ifite eccentric ebyiri cyangwa eshatu) kandi zikoresha ibyuma bifunga byicayeho cyangwa biramba. Bitandukanye nabyo,valve z'ibinyugunyugu zikora neza cyaneKuba indashyikirwa mu guhangana n'umuvuduko mwinshi w'amashanyarazi, ubushyuhe bukabije, ibikoresho byangiza, no gutanga uburyo bwo kuzimya umuriro mu buryo butuma bidapfa gukwirakwira, bigatuma biba ngombwa cyane mu nganda zigezweho.

1.1 Ibice by'ingenzi bya Valve y'Ikinyugunyugu: Umubiri, Disiki, Igiti, Intebe, n'Ihuza ry'Umuyoboro w'Ingufu

Ibice by'ingenzi bya valve y'ikinyugunyugu biri mu byiciro bitanu by'ingenzi: umubiri wa valve, disc y'ikinyugunyugu, inkingi ya valve, intebe yo gufunga, n'ibice bihuza actuator.

•Umubiri w'ingufu: Igice cy'agapira k'inyuma gikoreshwa nk'igikonoshwa cy'ingenzi, gitwara umuvuduko w'imiyoboro n'imitwaro iringaniye mu gihe gikoreshwa nk'ishingiro ry'ibindi bice byose. Kiboneka mu buryo bwa wafer na lug, busanzwe bukorwa mu byuma bishongeshejwe, icyuma cya karuboni, cyangwa icyuma kitagira umugese.

•Disiki ya Valve: Disiki y'ikinyugunyugu ni ingenzi cyane mu gufungura, gufunga no gukurura. Imiterere yayo isa n'iya disiki, iboneka mu buryo burambuye cyangwa budasanzwe, igena neza imikorere yo kuziba no kudashira. Igomba kurwanya ingese no gushwanyagurika.

•Igiti cya Valve: Uruti rwa valve rwohereza ingufu, ruhuza actuator na disiki kugira ngo ikoreshwe mu kuzunguruka. Ubusanzwe ikorwa mu cyuma kitagira umugese, ifite imiterere ikomeye kandi minini cyane yo gukoreshwa mu buryo bunini kandi bufite umuvuduko mwinshi kugira ngo budahinduka cyangwa ngo buhinduke.

•Intebe ya ValveIntebe yo gufunga ni ingenzi cyane kugira ngo ifungwe neza. Iza mu bikoresho by'icyuma bifunga neza cyangwa bifunga neza, bifatanye neza na disiki kugira ngo hatavamo amazi.

•Actuator: Ibice bihuza actuator birimo imigozi, ibikoresho byo mu bwoko bwa worm, na actuators z'amashanyarazi/pneumatic. Bitanga torque ikenewe mu gufungura no gufunga, bigatuma habaho imikorere y'intoki ndetse no kugenzura kure mu buryo bwikora. Ibice byose bikorana kugira ngo bigenzure imikorere ihamye, gufunga neza, no kugenzura neza valve y'ikinyugunyugu.

1.2 Isesengura ry'amahame y'imiterere y'icyuma gikingira imikorere myiza

Valve y'ibinyugunyugu ifite imikorere myiza ni valve y'ibinyugunyugu ifite imiterere yihariye, ikwiriye cyane mu kugenzura cyangwa kugenzura urujya n'uruza rw'amazi n'umuvuduko mu bikorwa nk'amazi yo mu robine, amazi yo mu nganda, amazi yanduye, umwuka, HVAC, gaze yo mu mujyi, na LPG. Iyo ifunze, valve nta kintu na kimwe isohora.

Imiterere y'intebe y'agati ifite igishushanyo mbonera cya COS curve kidafunze, kigabanya gukururana hagati ya disiki n'intebe, kigabanya imbaraga za actuator, kandi kikongera igihe cy'intebe. Uburyo bwo gukururana kwayo busa n'ubwa vali ifite impande ebyiri. Ubuso bwo gukururana bwa disiki ni uruziga, bigatuma habaho gukorana neza mu gihe cyo gukururana. Gukururana kugabanuka, cyane cyane ku gice cyo gupfundikira, byongera cyane igihe cyo gukora. Impeta y'icyuma iri imbere mu mpeta y'intebe ihita iziba icyuho kiri hagati y'inkingi n'impeta y'intebe iyo inkingi ihuye n'imbaraga zidahuye, bikuraho amahirwe yo gukururana kw'agati.

•Umuyoboro wa COS: Imiterere ya COS curve yo kuziba igenzura ko nta torque yiyongera mbere yuko iziba. Mu gihe cyo kuziba, disiki ikorana n'impeta y'intebe icyarimwe mu muzenguruko wose wa 360°, ikagabanya torque, ikagabanya torque, ikongera igihe cyo kwicara, kandi ikarinda gusohoka burundu mu gihe kirekire. Kugabanuka kwa torque no kuziba bituma ikoreshwa rya actuators zikoresha ingufu nke, bikagabanya ikiguzi cy'umukoresha.

•Disiki ifite imashini ikoze mu buryo bw'uruziga: Disiki ikozwe mu buryo bw'umuzenguruko, aho igice cyose cy'ubuso bwo gufunga kigize igice cy'umuzenguruko. Disiki n'impeta y'intebe byombi bitunganywa ku buryo bumwe bw'umuzenguruko, bigatuma habaho umwanya muto kandi nta gushwanyagurika. Disiki izenguruka neza, ndetse no ku buso bwo gufunga hejuru no hepfo. Nubwo ikoraho, ubuso bwo gufunga buraryoshye cyane, bigabanya imbaraga kandi byongera imikorere yo gufunga.

•Valve y'ikinyugunyugu ifite PTFE ikora neza cyane: Iyi valve ifite umwobo w’umubiri upfundikiyemo PTFE kandi ikoreshwa cyane mu biribwa, imiti, ibikoresho by’ikoranabuhanga, n’ibindi bikorwa by’isuku mu kugenzura cyangwa kugenzura urujya n’uruza rw’amazi atandukanye, ndetse no mu nganda zikora imiti irimo aside ikomeye, alkali zikomeye, n’imyuka ihumanya cyane. Iraramba cyane, ikora neza cyane, kandi irwanya ingese, bigatuma nta gusohoka kw’amazi iyo ifunze.

•Igishushanyo mbonera cy'ikimenyetso cy'ubwoko bwa I: Igishushanyo mbonera cy'impeta y'urupapuro gikomeza gukora rubber na Teflon mu buryo butari bumwe ariko byuzuzanya, bikongera ubushobozi bwo gufunga. Gukoresha rubber byongera uburibwe ku rubber mu gihe bigabanya ingano y'urubber rukenewe, bikuraho ibyago byo gufunga disiki mu mwanya ufunze bitewe no kwaguka kwa rubber bitewe n'izamuka ry'ubushyuhe.

Uburyo bwo Gufunga bw'Igishushanyo Gishya cya Valve y'Ikinyugunyugu Gikora Cyane:

a. Umugozi wa PFA ufite ubugari bwa mm 3 cyangwa urenzeho urinda neza kwinjira mu myuka itandukanye kandi utanga ubudahangarwa bukomeye bwo kwangirika.

b. Imashini zo gupakira zongerwaho amasoko yombi mu dusanduku two hejuru n'utwo hasi kugira ngo zikureho ingaruka z'ihindagurika ry'ubushyuhe ku gufunga.

2. Valve zikora neza cyane ugereranije n'izisanzwe z'ibinyugunyugu: Itandukaniro ry'ingenzi

3.4. Gufunga mu cyerekezo kibiri:Irinda amazi ava mu cyerekezo icyo ari cyo cyose.

3.5. Igihe kirekire cyo gukora:Intebe zikomeye z'icyuma n'ibikoresho bigezweho bitanga imbaraga mu mirimo yo kwangiza cyangwa kwangiza.

3.6. Igiciro gito cy'ubuzima:Kugabanya ibikorwa byo gusana, igihe kirekire cyo gusimbuza, no gukora neza bigabanya ishoramari ryinshi rya mbere.

3.7. Ubushobozi bwo gukurura ibyuma:Itanga imiterere myiza yo kugenzura amazi ugereranije n'udupira tw'ibinyugunyugu dusanzwe, cyane cyane imiterere ya triple offset.

4. Ubwoko bw'amavaluve y'ibinyugunyugu akora neza cyane

Valve z'ibinyugunyugu zikora neza cyanezishyirwa mu byiciro ahanini hakurikijwe imiterere ya disiki yazo:

4.1.Valves ebyiri z'ikinyugunyugu zikoreshwa mu gusimbuza(Uburyo bubiri bwo gutandukanya ibintu):

Uruti rushyirwa inyuma y'umurongo wo hagati wa disiki (offset ya mbere) no hanze y'umurongo wo hagati w'umuyoboro (offset ya kabiri). Ibi bituma habaho imikorere ya kamera, bigakuramo agafunga ka disiki kure y'intebe mu gihe cyo gufungura kwa 10°, bigagabanya kwangirika. Ni byiza ku ntebe zikomeye cyangwa iz'icyuma mu gihe zikoreshwa mu buryo buri hagati cyangwa bwinshi.

4.2. Valves eshatu z'ikinyugunyugu (TOV / Triple Eccentric):

Irimo ibice bibiri by’igishushanyo cya offset ebyiri hamwe n’ikindi cya gatatu: imiterere y’ubuso bw’intebe. Ibi bituma habaho gukorana kw’icyuma n’icyuma, bigakuraho gushwanyagurika mu gihe cyose cy’igikorwa.Valves eshatu z'ikinyugunyugu zikoreshwa mu gihe gitokuba indashyikirwa muri serivisi zikomeye cyane - ubushyuhe bukabije, umuvuduko mwinshi, ibikoresho byangiza, n'aho icyemezo cyo kwirinda inkongi y'umuriro gikenewe (API 607/API 641). Ni bo ba mbere muvalve z'ibinyugunyugu zikora neza cyane.

5. Ibikoresho, Ingano, n'Isuzuma ry'Umuvuduko
