Vali z'umupirabigira imiterere myinshi, ariko muri rusange ni bimwe. Ibice byo gufungura no gufunga ni ibice by'uruziga bizunguruka, bigizwe ahanini n'intebe z'abafunga, imipira, impeta zo gufunga, inkingi z'abafunga n'ibindi bikoresho byo gukora. Urufatiro rw'abafunga ruzunguruka dogere 90 kugira ngo bagere ku gufungura no gufunga kwa bafunga. Udupira tw'abafunga dukoreshwa ku miyoboro kugira ngo dufunge, dukwirakwize, dugenzure uburyo bwo gutembera no guhindura icyerekezo cy'inzira. Intebe y'abafunga ikoresha imiterere itandukanye yo gufunga intebe hakurikijwe imiterere itandukanye y'akazi. Umubiri w'abafunga umupira w'ubwoko bwa O ufite umupira ufite umwobo wo hagati unyuramo ufite umurambararo ungana n'umurambararo w'umuyoboro. Umupira ushobora kuzenguruka mu ntebe yo gufunga. Hariho impeta ya annular elastic ku mpande zombi mu cyerekezo cy'umuyoboro. Vale y'umupira w'ubwoko bwa V ifite imiterere isa na V. Imbere y'abafunga ni 1/4 cy'uruziga gifite agace ka V. Ifite ubushobozi bwo gutembera bunini, intera nini ishobora guhindurwa, imbaraga zo gukata, kandi ishobora gufungwa neza. Ikwiriye cyane cyane mu bihe by'amazi aho ibikoresho bifite fibrous.
1. Imiterere ya valve y'umupira wo mu bwoko bwa O:
Valve y'umupira wo mu bwoko bwa O igenzura icyerekezo cy'ubugari bw'umupira binyuze mu kuzunguruka umupira kuri 90°, bityo umwobo unyuramo ushobora guhinduka, bityo bigatuma valve y'umupira ifunguka kandi igafungwa. Valve y'umupira wo mu bwoko bwa O ikoresha imiterere ihindagurika cyangwa idahinduka. Ibice bigenda bikozwe mu bikoresho byishyiramo amavuta bifite coefficient nto cyane yo gukururana, bityo imbaraga zo gukora zikaba nto. Byongeye kandi, gufunga amavuta yo gufunga igihe kirekire bituma imikorere yoroha. Ibyiza byayo ni ibi bikurikira:
-
Valve y'umupira yo mu bwoko bwa O ifite ubushobozi buke bwo kudakoresha amazi
Muri rusange, valve z'umupira zifite imiterere ibiri: umurambararo wose n'umurambararo muto. Uko imiterere yaba iri kose, coefficient yo kurwanya amazi mu muyoboro w'umupira ni ntoya. Valve zisanzwe z'umupira zigororotse, zizwi kandi nka valve z'umupira zigenda zigana ku muyoboro. Umurambararo w'umuyoboro ungana n'umurambararo w'imbere w'umuyoboro, kandi igihombo cyo kurwanya amazi ni ukurwanya gusa uburebure bumwe bw'umuyoboro. Iyi valve y'umupira ifite ubushobozi buke bwo kurwanya amazi kurusha valve zose. Hari uburyo bubiri bwo kugabanya imbaraga zo kurwanya imiyoboro: bumwe ni ukugabanya umuvuduko w'amazi mu kongera umurambararo w'umuyoboro n'umurambararo w'umuyoboro, ibyo bikazongera cyane ikiguzi cy'imiyoboro. Ubwa kabiri ni ukugabanya imbaraga zo kurwanya imiyoboro, kandi valve z'umupira ni zo mahitamo meza.
-
Valve y'umupira yo mu bwoko bwa O irahinduka vuba kandi ku buryo bworoshye
Valve y'umupira ikeneye kuzunguruka dogere 90 gusa kugira ngo ifunguke cyangwa ifungwe neza, bityo ibashe gufungurwa no gufungwa vuba.
- Valve y'umupira yo mu bwoko bwa O ifite ubushobozi bwo gufunga neza
Intebe nyinshi z'imipira zikozwe mu bikoresho bya elastic nka PTFE, bikunze kwitwa soft-sealing ball valves. Soft seating ball valves zifite ubushobozi bwo kuziba neza kandi ntizisaba ubukana bwinshi no gutunganya neza ubuso bwo kuziba valve.
-
Valve y'umupira yo mu bwoko bwa O imara igihe kirekire
Kubera ko PTFE/F4 ifite ubushobozi bwiza bwo kwisiga, ubushobozi bwo gukururana n'umubumbe ni buke. Bitewe n'ikoranabuhanga rigezweho ryo gutunganya, ubukana bw'umupira buragabanuka, bityo bikongera cyane igihe cyo gukora cy'umupira.
-
Valve y'umupira yo mu bwoko bwa O ifite ubwizerwe bwinshi
Impande zombi z'umupira n'intebe ya valve ntibizagira ibibazo byo gushwanyagurika, kwangirika vuba n'ibindi bibazo;
Nyuma y'uko uruti rw'umugozi ruhinduwe rukaba urwubatswemo, impanuka ishobora gutuma uruti rw'umugozi ruguruka bitewe n'uko umuvuduko w'amazi ugabanutse;
Utwuma tw’umupira dufite inyubako zirwanya umuriro kandi zirinda umuriro dushobora gukoreshwa mu miyoboro itwara peteroli, gazi karemano na gazi y’amakara.
Igice cy'imbere cya valve (umupira) ya valve y'umupira wo mu bwoko bwa O ni uruziga. Ukurikije imiterere y'icyuma, intebe y'umupira iba iri mu ntebe ku ruhande rw'umubiri wa valve iyo uyipfundikiye. Ibice bigenda bikozwe mu bikoresho byisiga bifite ubushobozi bwo gukururana gato cyane, bityo imbaraga zo kuyikoresha zikaba nto. Byongeye kandi, gufunga amavuta yo kuyipfundikira igihe kirekire bituma imikorere yoroha. Muri rusange ikoreshwa mu guhindura imyanya ibiri, imiterere y'inzira ni ugufungura vuba.
Iyo valve y'umupira wo mu bwoko bwa O ifunguye neza, impande zombi ntiziba zikinguye, zigakora umuyoboro ugororotse ufite uburyo bwo gufunga bw'impande zombi. Ifite ubushobozi bwiza bwo "kwisukura" kandi ikwiriye igihe cyo gukata ahantu habiri hadasukuye cyane kandi hafite fibre. Igice cy'umupira gihora gitera gushwanyagurika na valve mu gihe cyo gufungura no gufunga valve. Muri icyo gihe, gufunga hagati y'igice cy'umutima wa valve n'intebe ya valve bigerwaho binyuze mu mbaraga zo gufunga mbere y'uko intebe ya valve ikanda ku gice cy'umutima. Ariko, kubera intebe ya valve yoroshye gufunga, imiterere myiza ya mekanike n'iy'umubiri ituma imikorere yayo yo gufunga iba myiza cyane.
2.Imiterere ya valve y'umupira ifite ishusho ya V:
Igice cy'imbere cy'umupira w'urushundura gifite ishusho ya V gifite imiterere isa na V. Igice cy'imbere cy'urushundura ni igishishwa cy'uruziga cya 1/4 gifite ipfundo rimeze nka V. Gifite ubushobozi bwo gutemba cyane, ahantu hanini hashobora guhindurwa, imbaraga zo gukata, kandi gishobora gufungwa neza. Kirakwiriye cyane cyane amazi. Ahantu ibikoresho bifite fibroids. Muri rusange, vali z'umupira zifite ishusho ya V ni vali z'umupira zifunze rimwe. Ntizikwiriye gukoreshwa mu buryo bubiri.
Hari ubwoko bune bw'inyuma bufite ishusho ya V, dogere 15, dogere 30, dogere 60, dogere 90.
Inkombe ifite ishusho ya V igabanya imyanda. Mu gihe cyo kuzenguruka k'umupira, inkombe y'icyuma gityaye ifite ishusho ya V ifatana n'intebe ya valve, bityo igaca imigozi n'ibintu bikomeye biri mu mazi. Ariko, valve zisanzwe z'umupira ntabwo zifite iyi nshingano, bityo biroroshye gutuma imyanda ya fibre ifatana iyo ufunze, bigatera ibibazo byo kubungabunga no gusana. Kubungabunga ni ikibazo gikomeye. Imbere ya valve ya valve ifite ishusho ya V ntabwo izafatirwa n'imigozi. Byongeye kandi, bitewe n'aho flange ihurira, biroroshye kuyikuraho no kuyiteranya nta bikoresho byihariye, kandi kuyibungabunga biroroshye iyo valve ifunze. Hariho ingaruka y'umukasi imeze nk'ibanga hagati y'agace ka V n'intebe ya valve, idakora gusa nk'isuku ahubwo inabuza inkingi ya valve gufatana. Igice cya valve, igifuniko cya valve n'intebe ya valve bikoresha imiterere y'icyuma igera ku ngingo, kandi hakoreshwa coefficient nto yo gukururana. Urufatiro rwa valve rufite impera, bityo torque yo gukora iba nto kandi ihamye cyane.
Valve y'umupira ifite ishusho ya V ni imiterere izunguruka y'impande z'iburyo ishobora kugera ku miterere y'amazi. Ishobora kugera ku bipimo bitandukanye by'ingano hakurikijwe inguni ifite ishusho ya V y'umupira ufite ishusho ya V. Valve y'umupira ifite ishusho ya V muri rusange ikoreshwa hamwe n'ibikoresho bikoresha valve n'ibipimo kugira ngo igere ku miterere ingana. , Igice cy'imbere cy'umupira gifite ishusho ya V kibereye cyane mu bihe bitandukanye byo gukosora. Ifite ingano nini y'umuvuduko, igipimo kinini gishobora guhindurwa, ingaruka nziza zo gufunga, nta bushishozi mu mikorere yo gukosora, ingano nto, kandi ishobora gushyirwaho ihagaze cyangwa itambitse. Ikwiriye kugenzura gaze, umwuka, amazi n'ibindi bikoresho. Valve y'umupira ifite ishusho ya V ni imiterere izunguruka y'impande z'iburyo, igizwe n'umubiri wa valve ifite ishusho ya V, actuator y'umwuka, positioner n'ibindi bikoresho; ifite imiterere y'umuvuduko ingana; ifata imiterere ifite ishusho ebyiri, ifite torque nto yo gutangira, kandi ifite ubushobozi bwo kumva no kumva neza, ubushobozi bwo gukata neza.
