Kwesango uMlilo: iintlobo iimpawu kunye neempawu isixhobo

Kuba ingcinezelo umlilo ifuna yonke inkqubo eyenziwa imibhobho yamanzi, namathumbu, iivelufa kunye nezinye iintlobo lweziqalelo. Ezi zixhobo ukuvumela ukuba linikezele ngamanzi ngqo de ucinezelo. Kanjalo inkqubo zokucima umlilo akaphelelanga ngaphandle kwezivalo ezikumgangatho ophezulu ukuya apho vana ngumlilo. Khawuve oko iintlobo kukho, iiyantlukwano zabo iingenelo ngokusebenzisa.

izenzo olumisiweyo

Kuyo yonke imicimbi enxulumene neenkqubo zokukhusela umlilo, ulawulo lwenzeka ngokubhekisele maxwebhu alandelayo:

• NPB 154-2000. Lo mmiselo utyhila zonke iinkcukacha malunga ubuchule lomlilo, izivingco, imibhobho umlilo. Ukwalawula isahlulo zobugcisa: iimfuno zokhuseleko kunye neendlela zokusebenza test.
• GOST P 53278-2009. uxwebhu Previous ibhekiselele Standard njengoxwebhu esisiseko, enika inkcazelo echanileyo kakhulu amaxabiso ezithile zolawulo.
• Federal Law №123. Lo mthetho olawula imeko ngokusemthethweni xa ngomlilo, kwakunye amanyathelo okuthintela kuyo.

Le migaqo elawula zonke iindawo, ukususela imveliso kwezivalo phambi ukusebenzisa kunye novavanyo.

Yintoni na?

kwesango Umlilo (aka vana) yinxalenye crane. Zixhonywe ngaphakathi kwinkqubo yonikezelo lwamanzi kuba umlilo zokucima ubushushu ulwelo okanye igesi ku-50 ° C. Enye ekupheleni kwale mveliso ziya kuba ngokohlobo izingxobo, kwaye eyesibini - tsapkovy (oyindoda) ukuba kokujikeleza kokuxhuma intloko coupling. Xa uyilo, iivelufa umlilo zahluke akukho ukusuka noogxa oluqhelekileyo. Umahluko - kuphela ubukhulu kunye eziphathekayo. Xa design wabo, bona babe handwheel bushing nokupakisha nobubovu umzimba intloko, intonga azinamsonto, ikheswa vana kunye gasket.

iintlobo

iintlobo ezininzi zingahlukaniswa ngokwemimiselo ezahlukeneyo:

• Ngokutsho uhlobo ufakelo - itshaneli, eludongeni.
• Ngokubhekiselela isakhiwo igobhogobho engaphandle - angle (90 ° okanye 125 °), nokuthetha, nge-flow.
• Xa umsebenzi - kuvaleka, uzivalele-off nokulawula ezizodwa.
• Le nkcazelo - isinyithi, nobhedu.
• Njengoko enobubanzi zangaphakathi - 50 mm okanye mm 65.
• Ngokutsho uhlobo lonxibelelwano - nokuhlangana / bamba, iklatshi / hoe. Hoe isivingco umbhobho umlilo ivumela uqhagamshelwano umbhobho (umlilo ithumbu ferrule).

Iintlobo ngeentlobo ukuhlela aluchaphazeli umgangatho osisiseko kwase - ukuthembeka.

Iimfuno ukuba ivelufa

Kukho inani nezidingo kwemithambo umlilo:

• uphawu iimveliso kunye nemixube;
• NW - ukususela-40 ukuya kuma-65 mm;
• xi ukusebenza xa amanzi - hayi ngaphantsi kwe-1 MPA;
• uxinzelelo osebenza phantsi ivelufa;
• lobushushu yokusebenza kufuneka ingadluli-50 ° C;
• inani revolutions phambi lokuvula - 4 ukuya kowe-6, kuxhomekeke sicatshulwa ngegama;
• Flywheel ujikelezo - ngasekunene;
• crimping inyanzelekile ukuba kwiiyure ezili-12 phambi kwentengiso.

Zonke ezi mfuno kwenza kube lula ngokukhawuleza emlilweni iimeko ukuqala inkqubo esebenza phantsi kweemeko ezinzima.

uphumezo ezibonakalayo

ivelufa umlilo ezenziwe ongangokugibisela ngentsimbi nobhedu. Oku kungenxa yokuba amanqaku ezinjalo kufuneka ilifa amandla nokuthembeka. Iron, nobhedu, kunye neempawu ezifana zisenokwahluka, ezizezi anticorrosive, iyahlala nokukwazi ukumelana uxinzelelo oluphezulu le nkqubo. Le propati kuvumela ukusetyenziswa iimveliso ezifana ixesha elide.

uphawu

Iipropati Crane ekuboniswa kuphela kwileta, imiqondiso yedijithali, kodwa ngesimilo nomzimba umbala ukupeyinta. Le nokumakishwa isicelo yi ulahle kwaye kufuneka siqulathe le datha ilandelayo:

• enobubanzi obungu;
• uxinzelelo ngegama;
• izinto istili;
• uphawu kunye / okanye igama yomvelisi;
• kolwalathiso medium ukusebenza;
• unyaka;
• utolo-isalathisi ulwalathiso bume yokusebenza;
• gasket abizwa ngokuba esisangqa lokutywina njalo njalo. d.

Ezi ntlobo eziseleyo nokumakishwa isicelo ngokungqinelana neemfuno zolawulo kunye nemimiselo.

Lwemibala uveza izinto ezenziwe yezindlu kuwo:

• Grey,, castings oluthambileyo intsimbi ductile - Black;
• grey - carbon yesinyithi;
• blue - ingxubevange yesinyithi;
• blue - ingxubevange high intsimbi, emelana nokudliwa ngumhlwa kunye aluminiyamu ubushushu ezingatshiyo.

Njengoko sibonile, ivelufa umlilo iimpawu zazo uchaza ngokupheleleyo ukuba zokuphawula.

Ukufakelwa nokugcinwa neempawu

Iintlobo ezahlukeneyo loyilo ivumela ivalve xa kuqhambuke umlilo kuso nasiphi na isikhundla. Ezingavumelekanga ukufakelwa flywheel phantsi. Xa iimeko umlilo, umsebenzi kwinkqubo yonikezelo lwamanzi kufuneka ezifikelelekayo lula. Xa likaxakeka, zonke izibalo yesibini, ngoko ivelufa kufuneka mazivulwe kuphela 4-6 amathuba. Uyilo Modern akuvumela wenze iintshukumo ezifana ngaphandle zokuxhathisa ezongezelelweyo. Xa inkqubo eqhubekayo kufuneka babonwe ukuvuza. Xa ufaka ivalve phezu unxulumano conduit ukuba liqiniswe yaye itywina ndlala gasket. Phambi ufakelo, umbhobho kufuneka zicocwe ngenyameko ngaphandle ukungcola nesanti.

Hardware Requirements:

• Unako ukufaka vana usebenzisa intloko coupling.
• Xa ukusilela (ukonakala) itywina ndlala indawo yayo.
• Kwimpahla kuxhomekeke ekubeni ukuthambisa ajikeleze ngamaxesha.
• Rhoqo izixhobo Test.
• Ekupheleni ithuba lokugcinwa kwezinto zento waqhaqhwa wathumela ukuba ngokurisayikilisha.
• Ubomi inkonzo kwemithambo ixhomekeke ufakelo wabulawa ngokufanelekileyo kunye nolondolozo.

Thulani-off valve umlilo - enye yamacebo umlilo-ekulweni ezibaluleke kakhulu kwinkqubo. On umgangatho wayo kunye nokufakwa efanelekileyo ixhomekeke isantya kwaye amathuba ukusetyenziswa kwayo ngexesha likaxakeka. Kwaye oku kuxhomekeke ebomini bomntu. Ngoko ke, amashishini zithintelwe ngokungqongqo ukusetyenziswa kwezixhobo zokulwa umlilo, kungekhona amaxwebhu olumisiweyo engqinelanayo.

Xa uthenga isixhobo ezifana isivingco, kufuneka acele isatifikethi bokuthobela. Nikelani ingqalelo mshini kwi ubungakanani lisetyenziswa ngokuchanekileyo nokuba iinkcukacha ezifunekayo. Xa umcimbi kufuneka uthathe imveliso ye imvelaphi ezingaqondakaliyo. Abayi musa bahluka umgangatho efanelekileyo kunye nokuthembeka. Gcina kwi ezi mveliso ayikho kuyimfuneko, baxhomekeke ngqo kubomi babantu kunye nempilo.
