Ubumenyi bwa Valve: Gukoresha torque iranga ibice byaciwe na ball ball yumunsi kubungabunga buri munsi kugenzura

Imikorere ya torque iranga umurongo wo gukata-valve ni muremure hagati no hasi kumpande zombi. Impamvu yibi bintu nuko, mugihe iyo valve yaciwe iri mumwanya wo hagati, isukari ihagarikwa nisahani yikinyugunyugu, ikazenguruka amazi yikinyugunyugu, izakorwa kumpande zombi zicyapa kinyugunyugu kizunguruka, ikinyugunyugu isahani itanga umwanya-wimbere wamazi, umwanya uratwarwa kugirango uhagarike isahani yikinyugunyugu. Hamwe no gufungura cyangwa gufunga isahani yikinyugunyugu, ingaruka zumuzunguruko ziterwa namazi kumpande zombi zisahani yikinyugunyugu igenda iba nto kandi ntoya, kugeza igihe igishushanyo mbonera gikora igishushanyo kiranga umupira ugabanuka bisa cyane nibya valve yaciwe, impamvu nyamukuru nayo ni ukubera ingaruka zamazi murwego rwatewe nimpinduka zinjira.
(a) Ibikorwa biranga valve yaciwe
Imikorere ya torque iranga umurongo wo gukata-valve ni muremure hagati no hasi kumpande zombi.
Impamvu yibi bintu nuko, mugihe iyo valve yaciwe iri mumwanya wo hagati, isukari ihagarikwa nisahani yikinyugunyugu, ikazenguruka amazi yikinyugunyugu, izakorwa kumpande zombi zicyapa kinyugunyugu kizunguruka, ikinyugunyugu isahani itanga umwanya-wimbere wamazi, umwanya uratwarwa kugirango uhagarike isahani yikinyugunyugu. Hamwe no gufungura cyangwa gufunga isahani yikinyugunyugu, ingaruka zamazi kumpande zombi zikinyugunyugu zatewe numuyaga wa vortex ni nto kandi ntoya, kugeza igihe inkubi y'umuyaga igabanutse, muriki gihe kurwanya ubukana bwibisahani byikinyugunyugu nabyo ni bito na bito, bivamo hagati murwego rwo hejuru, ibintu biranga impande zombi zishusho. Umuyoboro nyawo ukora muburyo bwo gufungura amarembo ya valve nini kuruta iyo muburyo bwo gusoza. Impamvu nyamukuru nuko hydrodynamic torque iterwa namazi yo ku isahani yikinyugunyugu ihora yerekeza kuri Angle ifunga.
Umuyoboro munini cyane wimikorere ya valve idahagaritswe na valve iboneka mumwanya wo hagati, mugihe itara rinini cyane ryimikorere ya gari ya moshi yahagaritswe ibaho iyo valve yumuryango ifunze, cyane cyane kubera itara ryongeweho gufunga.
Icyicaro cya valve cyaciwe na valve gusa kugirango kizenguruke gusa, disiki yacyo nintebe ubwayo ntabwo ifunze imbaraga. Kugirango ukore disiki ihagaze neza (kurangirira kumwanya wagenwe), uburyo bumwe busaba kugabanya iyindi ifite imbaraga zo gufunga intebe. Nyuma yo kugabanya umubumbe wongeyeho, umuvuduko wimpande urashobora kwiyongera kugeza kumirongo myinshi, mugihe umuriro nyirizina wagabanutse. Ibi bituma ibintu bimwe na bimwe bifatika biranga valve yaciwe (nk'impinduka zose hamwe n'umuriro nyawo ukora) kuba hafi yandi marembo, bifasha mugukoresha ibikoresho byamashanyarazi.
Kugirango hafungwe ku gahato valve yaciwe, umwanya wacyo wo gufunga ugomba kugenwa nu muriro nyirizina ukora uzamuka ku gipimo gisanzwe.
(2) Valve ibiranga imikorere Valve ikora ya torque ibiranga:
Imikorere ya torque iranga igishushanyo cyumupira wumupira urasa cyane nuwaciwe na valve yaciwe, impamvu nyamukuru nayo ni ukubera ingaruka zamazi atemba aterwa nimpinduka zinjira murwego. Ingaruka z'umuyaga wa serwakira zigabanuka buhoro buhoro no gufungura cyangwa gufunga valve.
Umupira wumupira kuva gufungura kugeza gufunga, icyicaro cyizunguruka cyerekezo ni 90%, umupira wumupira kugirango ushireho imipaka. Igice cyo gutangira cyangwa gufunga igice cyumupira kigomba kugenwa nicyerekezo cyo kuzenguruka intebe ya valve, bityo umupira wumupira uhagaze ukurikije gahunda yurugendo.
Kubungabunga buri munsi clamp cheque valve valve kubungabunga buri munsi ububiko bwa flange ball valve bugomba kuba butarimo amazi, butagira amazi, butarinda amazi, hamwe nigifuniko cya flange neza, bibitswe amezi arenga 12 yumuryango wamarembo, gusaba bigomba gusubirwamo kugirango ubuziranenge buhamye.

Flange ball valve usaba
1, icyapa cyuruganda cyerekana ko flange ball valve yemerewe gukora mubushyuhe bunini cyane ugereranije nubushyuhe buke bwo gukora bwurwego rwa King Kong.
2, flange ball valve hamwe na PTFE cyangwa RTFE ibikoresho byumuvuduko mwinshi wamarembo ya valve hamwe na kashe ya hydraulic, ubushyuhe bwakazi bugomba kuba hagati ya -290C kugeza 2000C. Ubushyuhe bwo gukora bwubundi bwoko bwumuvuduko mwinshi wamarembo hamwe na kashe ya hydraulic bigomba kugenzurwa nuruganda rwa KI.
3, diameter nominal yicyiciro cya valve (PN), irashobora kwerekana ko valve mumiterere yubushyuhe busanzwe ari umuvuduko mwinshi. (Kurugero: PN4.0, byerekana ko ubushyuhe bwo gukora -290C ~ 380C nyuma yumuvuduko mwinshi wa 40 Bar (4.0MPa)).

Imwe, umupira wamaguru ureremba
Umupira wa valve umupira ureremba hejuru no munsi, bitewe nigitutu cyibikorwa byakazi, umupira urashobora gutanga offset runaka kandi ugafatana hejuru yumusozo wanyuma, kugirango umenye neza ko isohoka rifungwa. Imiterere yimipira yumupira iroroshye, imiterere yoroheje, ariko umupira ufata umutwaro wibitangazamakuru byose kumpeta yinjira no gusohoka, bityo rero tugomba kumva impeta ya kashe ishobora kwihanganira imipira yumurimo wo hagati. Iyi miterere ikoreshwa mumashanyarazi yo hagati na make.
Babiri, umupira wuzuye
Umupira wa valve umupira uhoraho, nyuma yimbaraga ntizimurwa. Imipira ihamye yumupira ije ihindagurika ihindagurika ryumuvuduko mwinshi. Nyuma yumuvuduko wakazi wibikoresho, umuvuduko mwinshi w irembo ryimuka, kugirango impeta ifunga kanda kumupira kugirango umenye neza. Mubisanzwe mumyenda yumupira, uruziga rwo hasi rufite ibyuma bizunguruka, urumuri ruto rwo kugenzura, rukwiranye numuvuduko mwinshi hamwe numubiri muto wa kalibiri. Kugirango ugabanye urumuri rukora rwumupira wumupira no kongera urwego rwokwizerwa rwa kashe, skeleton ifunze umupira wumupira wagaragaye mumyaka yashize. Ntabwo ari ugusiga amavuta yihariye hagati yubuso kugirango habeho urwego rwamavuta ya peteroli, atezimbere ubukana kandi agabanya umuriro wimikorere. Birakwiriye cyane kumupira wumupira ufite umuvuduko mwinshi na diameter nto.
Bitatu, imipira yumupira
Umupira wumupira wumupira urahagaritswe. Umupira hamwe numuvuduko mwinshi w irembo rya kashe impeta ikozwe mubikoresho bigize ibyuma, igitutu cyo gufunga ni kinini cyane, bitewe nigitutu cyibikoresho byarenze ibisabwa byo gufunga, gukenera kongera imbaraga ziva hanze. Irembo ry'irembo rikwiranye na ultra-high pressure hamwe nubushyuhe bwo hejuru. Umwanya wa elastike kugirango ufungure igikonjo cyoroshye munsi yumuzingi, hanyuma ubone imbaraga za elastique. Iyo umuyoboro wumutekano uzimye, umupira urakingurwa numutwe wumutwe winkoni ya piston hanyuma valve yumuvuduko mwinshi winjira kugirango ugere kashe. Mbere yo kuzunguruka umupira, banza uhanure umutwe wa wedge, umupira hamwe no gusubira muri prototype isanzwe, kugirango umupira hamwe na valve ihagarike hagati yu cyuho, bishobora kugabanya imikorere yimikorere yubuso bwubuso.

Umupira wumupira ukurikije umwanya wumutekano wacyo urashobora kugabanwa muburyo butaziguye, inzira eshatu cyangwa Inguni iburyo. Imipira ibiri yanyuma ikoreshwa mugukwirakwiza ibikoresho no guhindura urujya n'uruza rw'itangazamakuru. Gushyira umupira wumupira no kubungabunga bigomba kwitondera ibintu bikurikira: 1. Kureka igice kizunguruka cyumukono wa valve. 2. Ntishobora gukoreshwa nka valve ya trottle. Imipira yumupira hamwe nibikoresho byohereza igomba guteranyirizwa hamwe.
Kubungabunga buri munsi clamp igenzura umupira
Kwoza umupira wa flange, kugirango usukure byimazeyo ivumbi risigaye, irangi ryamavuta nibindi byongeweho, nkamazi ashyushye ntibishobora gusukurwa, ntibishobora gusenya ikibaho cyamavuta hamwe nibice munsi yacyo, byibasiwe ninzoga nibindi bikoresho byogusukura. Flange ball valve isukura nyuma yisuku imaze guhinduka mbere yo gushiraho. Flange ball valve umubiri iracyafite igice gisigaye cyibikoresho, nanone munsi yigitutu runaka cyakazi. Mbere yo kubungabunga umupira wumupira, birakenewe kuzimya umupira wumupira mbere yuko byihutirwa guca valve, gufungura umupira wumupira ugomba gusanwa, no kurekura burundu flange ball valve amavuta yumuzunguruko wa plaque imbere yimikorere yimikorere.
