Kugenzura ikinyugunyugubivuga kuri valve ihita ifungura no gufunga disiki bitewe nuburyo bwo hagati ubwayo, kandi ikoreshwa mukubuza uburyo gusubira inyuma.Yitwa kandi cheque valve, inzira imwe, valve, reaction ya valve, hamwe numuvuduko winyuma.Kugenzura valve ni ubwoko bwa valve yikora, umurimo wingenzi wacyo ni ukurinda imigendekere yinyuma yikigereranyo, kubuza pompe na moteri ya moteri gusubira inyuma, no gusohora ibikoresho bya kontineri.Kugenzura valve nabyo birashobora gukoreshwa mugutanga imiyoboro ya sisitemu yubufasha aho umuvuduko ushobora kuzamuka hejuru yumuvuduko wa sisitemu.Kugenzura indangagaciro zishobora kugabanywamo ibice byo kugenzura (kuzunguruka ukurikije hagati ya gravit), kuzamura igenzura (kugendagenda kumurongo), no kugenzura ibinyugunyugu (kuzenguruka hagati).
Imikorere
Imikorere yikinyugunyugu igenzura ni ukwemerera gusa uburyo bwo gutembera mu cyerekezo kimwe no gukumira gutembera mu cyerekezo kimwe.Mubisanzwe ubu bwoko bwa valve bukora mu buryo bwikora.Munsi yigikorwa cyumuvuduko wamazi utemba mucyerekezo kimwe, flap ya valve irakinguka;iyo amazi atemba yerekeza muburyo bunyuranye, umuvuduko wamazi hamwe no guhurirana kwi flap ya flap ikora kumuntebe ya valve, bityo igabanya umuvuduko.
Ibiranga imiterere
Kugenzura ibinyugunyugu birimo swing cheque ya valve no kuzamura cheque.Igenzura rya swing rifite uburyo bwa hinge hamwe na disiki ya valve nkurugi ruba rwisanzuye hejuru yintebe ya valve.Kugirango hamenyekane neza ko claque ya valve ishobora kugera kumwanya ukwiye wubuso bwa valve buri gihe, claque ya valve yakozwe muburyo bwa hinge kuburyo claque ya valve ifite umwanya uhagije wo guhinduka kandi bigatuma clave ya claque mubyukuri kandi byuzuye ubaze kuri intebe.Ikibaho cya valve gishobora kuba gikozwe mubyuma, uruhu, reberi, cyangwa igifuniko cyogukora gishobora gushyirwaho icyuma, bitewe nibikorwa bisabwa.Iyo swing cheque ya valve ifunguye neza, umuvuduko wamazi usanga ntakumirwa, bityo umuvuduko ukamanuka muri valve ni muto.Disiki ya valve ya lift igenzura valve yicaye hejuru yikidodo cyintebe ya valve kumubiri wa valve.Usibye ko disiki ishobora kuzamurwa no kumanurwa mu bwisanzure, ahasigaye ya valve ni nka valve ifunze.Umuvuduko wamazi uterura disikuru hejuru yicyicaro cyicyicaro, kandi gusubira inyuma kwicyuma bituma disiki isubira kumuntebe ikagabanya umuvuduko.Ukurikije ibisabwa kugirango ukoreshwe, clave clav irashobora kuba ibyuma byose, cyangwa birashobora kuba muburyo bwa reberi cyangwa impeta ya reberi yometse kumurongo wikariso.Kimwe na valve ifunze, kunyura mumazi unyuze muri cheque ya lift nayo iragufi, bityo umuvuduko ukamanuka unyuze muri cheque ya lift ni nini kuruta iy'igenzura rya swing, kandi umuvuduko wo gutembera wa swing cheque urabujijwe gake.Ubu bwoko bwa valve bugomba gushyirwaho muburyo butambitse.
Ukurikije imiterere nuburyo bwo kwishyiriraho, cheque valve irashobora kugabanywamo:
1. Disiki ya kinyugunyugu igenzura ikinyugunyugu ifite ishusho ya disiki, kandi irazenguruka uruziga rw'umuyoboro wintebe.Kuberako umuyoboro wimbere wa valve uringaniye, irwanya umuvuduko ni muto ugereranije niyizamuka ryibinyugunyugu.Irakwiriye umuvuduko muke no kudasubira inyuma.Ibihe binini bya diametre hamwe nimpinduka nyinshi, ariko ntibikwiranye no gutembera neza, kandi imikorere yayo yo gufunga ntabwo ari byiza nkubwoko bwo guterura.Kugenzura ikinyugunyugu bigabanijwemo ubwoko butatu: valve imwe, valve ebyiri na valve nyinshi.Ubu bwoko butatu bugabanijwe cyane ukurikije diameter ya valve.Ikigamijwe ni ukurinda uburyo bwo guhagarara cyangwa gutembera inyuma no guca intege hydraulic.
2. Kugenzura ikinyugunyugu: Ukurikije uburyo bwa disiki ikora, igabanijwemo ubwoko bubiri: 1. Igenzura rya valve hamwe na disiki iranyerera igana umurongo uhagaze hagati yumubiri wa valve.Kugenzura ibinyugunyugu birashobora gushyirwaho gusa kumuyoboro utambitse.Umupira uzengurutse urashobora gukoreshwa kuri disiki ya diameter nto yo kugenzura.Imiterere yumubiri wa valve igenzura ikinyugunyugu ni kimwe nubwa globe ya globe (ishobora gukoreshwa mubisanzwe hamwe na globe ya globe), bityo coefficente yayo irwanya amazi ni nini cyane.Imiterere yacyo isa na valve ihagarara, kandi umubiri wa valve na disiki ni kimwe na valve ihagarara.Igice cyo hejuru cya disiki ya valve nigice cyo hepfo cyigifuniko cya valve gitunganywa hamwe nuyobora amaboko.Ubuyobozi bwa disiki burashobora kwimurwa hejuru no hepfo mubwisanzure muri valve iyobora.Iyo igikoresho gitemba epfo, disiki irakingurwa nimbaraga zo hagati.Iramanuka ku ntebe ya valve kugirango ibuze uburyo gusubira inyuma.Icyerekezo cyumuyoboro uciriritse winjira no gusohokera unyuze-unyuze mu kinyugunyugu kugenzura valve ni perpendicular yerekeza ku cyerekezo cyumuyoboro wintebe;vertical lift cheque valve ifite icyerekezo kimwe cyumuyoboro winjira usohoka nogusohoka nkumuyoboro wintebe ya valve, kandi irwanya umuvuduko ni muto ugereranije nubwoko bugororotse;2. Kugenzura valve aho disiki izunguruka hafi ya pin mu cyicaro cya valve.Kugenzura ikinyugunyugu bifite imiterere yoroshye kandi birashobora gushyirwaho gusa kumuyoboro utambitse, hamwe no gukora nabi.
3. Mumurongo wo kugenzura valve: valve disiki iranyerera kumurongo wo hagati wumubiri wa valve.Mu murongo wo kugenzura valve ni ubwoko bushya bwa valve.Nibito mubunini, urumuri muburemere, kandi nibyiza mubuhanga bwo gutunganya.Nimwe mubyerekezo byiterambere byigenzura.Ariko coeffisente yo kurwanya amazi ni nini gato ugereranije na swing check valve.
4. Kugenzura ububiko bwa compression: Iyi valve ikoreshwa nkamazi yo kugaburira amazi hamwe na valve ifunga.Ifite imikorere yuzuye yo kuzamura igenzura no guhagarika valve cyangwa inguni.
Mubyongeyeho, hari cheque zimwe na zimwe zidakwiriye gushyirwaho pompe isohoka, nkibibirindiro byamaguru, imizigo yuzuye, Y-ubwoko nubundi bugenzuzi.
Koresha n'ibisobanuro byihariye:
Iyi valve ikoreshwa nkigikoresho cyo gukumira isubira inyuma ryibikoresho mu miyoboro yinganda.
Ibyerekeye kwishyiriraho
Kwishyiriraho cheque valve bigomba kwitondera ibintu bikurikira:
1. Ntukemere ko cheque ya valve ifite uburemere mumuyoboro.Indangantego nini zigomba gushyigikirwa mu bwigenge kugira ngo zidatewe ingaruka n’umuvuduko ukomoka kuri sisitemu yo kuvoma.
2. Mugihe ushyiraho, witondere icyerekezo cyurugendo rwo hagati rugomba kuba ruhuye nicyerekezo cyumwambi watowe numubiri wa valve.
3. Kuzamura vertical flap cheque valve igomba gushyirwaho kumuyoboro uhagaze.
4. Kuzamura ubwoko bwa horizontal flap cheque valve igomba gushyirwaho kumuyoboro utambitse.
1. Ihame ryimikorere nibisobanuro byimiterere:
Mugihe cyo gukoresha iyi valve, ikigereranyo gitemba cyerekezo cyumwambi cyerekanwe mubishusho.
2. Iyo imiyoboro itembera mu cyerekezo cyagenwe, flap flap irakingurwa n'imbaraga zo hagati;iyo ikigereranyo gitemba inyuma, hejuru yikimenyetso cya flap ya flap hamwe nintebe ya valve bifunze kubera uburemere bwikibabi cya valve nigikorwa cyingufu zinyuranye ziciriritse.Funga hamwe kugirango ugere ku ntego yo kubuza uburyo gutembera inyuma.
3. Ubuso bwo gufunga umubiri wa valve hamwe na clack clack bifata ibyuma bidafite ingese.
4. Uburebure bwimiterere yiyi valve ihuye na GB12221-1989, naho ingano ya flange ihuza na JB / T79-1994.
Kubika, Kwinjiza no Gukoresha
5.1 Impera zombi zinzira zigomba guhagarikwa, kandi hari icyumba cyumye kandi gihumeka.Niba ibitswe igihe kirekire, igomba kugenzurwa kenshi kugirango irinde ruswa.
5.2 Umuyoboro ugomba gusukurwa mbere yo kwishyiriraho, kandi inenge zatewe mugihe cyo gutwara abantu zigomba kuvaho.
5.3 Mugihe cyo kwishyiriraho, ugomba gusuzuma neza niba ibimenyetso nibimenyetso byanditse kuri valve byujuje ibisabwa kugirango ukoreshwe.
5.4 Umuyoboro ushyirwa kumuyoboro utambitse hamwe na valve hejuru.
9. Ibishobora kunanirwa, Impamvu nuburyo bwo Kurandura:
1. Kumeneka ahuza umubiri wa valve na bonnet:
(1) Niba ibinyomoro bidakomeye cyangwa birekuwe neza, birashobora kongera guhinduka.
(2) Niba hari ibyangiritse cyangwa umwanda hejuru yikimenyetso cya flange, hejuru yikimenyetso hagomba gutemwa cyangwa umwanda ugomba kuvaho.
(3) Niba gasike yangiritse, igomba gusimburwa nindi nshya.
2. Kumeneka hejuru yikimenyetso cya clave hamwe nintebe ya valve
(1) Hariho umwanda hagati yikimenyetso, gishobora gusukurwa.
(2) Niba ikidodo cyangiritse cyangiritse, ongera usya cyangwa wongere ugaragare no gutunganya.
