Kwemithambo Ball - Ezahlukeneyo babetha Crane

izixhobo ezongezelelweyo evale-off ezabiwa kwemithambo ibhola, ngaphandle apho akunakwenzeka ukuba nomfanekiso imibhobho, esihambisa petroleum sukube kwaye ulwelo, igesi yendalo, okusela amanzi kunye namanzi mveliso, alkalis kunye asidi. Crane ngokwayo luhlobo semigudu yombhobho, luphawulwa element yokusebenza semilo ukulenza. Loo isisombululo uyilo akanguye ezintsha, yaye sisetyenziswe ngaphezu kwekhulu leminyaka, kodwa kwemithambo yezi ntlobo sele kutshanje kuphela kuba okuhlala ngokwenene kwaye athembekile.

Ke kaloku, ixesha wokwenziwa semigudu ibhola uye wasebenzisa izinto ultra ezifana ezifana PTFE kunye zerabha zokwenziwa. Kuyenzeka ukuba lula kakhulu kuyilo kwezivalo imibhobho kwaye yandisa kakhulu nokusetyenziswa kwezi zixhobo. Njengoko shutter ibhola vana kuphuma ibhola intsimbi kunye axis ubaleka nge kumngxuma apho ulwelo ukusebenza ongenakugqithwa. Kwimeko xa ubukhulu le mingxuma lilingane ubukhulu lwangaphakathi yombhobho kuthiwa yazala valve ngokupheleleyo. Ukuba ingaphantsi, crane kuthiwa nepolnoprohodnym.

Ngokuqhelekileyo kwasiso na iinqwelo, equka qhoqo PTFE, nawayenxuse ngeranti, kodwa isixhobo solawulo inika amandla ubuncinane. Kuba valve ibhola luphawulwa kwizikhundla ezimbini kakhulu, kwaye utshintsho esangweni position ngenxa ujikelezo usiba okhethekileyo. Kulo mzekelo, iivelufa ibhola zingasetyenziswa njenge control kunye kwezivalo enamandla umbhobho ovalelweyo-off. Phakathi ibhola valve ungakhetha modeli apho shutter ezinokususwa kuphela njengeziza ngokungqongqo ngenxa yengcinezelo medium ukusebenza, kodwa ezinye iimodeli shutter ke ubeka olusisigxina isekela ezizodwa.

Ibhola "ezidadayo" kweplagi ukholosile licinezelwe nxamnye umsesane lokutywina ethambileyo, ibekwe kwicala imveliso, ukubonelela ukutywina liphezulu icebo. Kodwa ke iintlobo semigudu ibhola lubonakala ngokuba sezingeni eliphezulu ukunganyangeki flow, ngoko ngalo mbhojana ovalelweyo-off lungasetyenziswa kuphela xa imibhobho nje omncinci kakhulu. Zonke elimisiweyo iibheringi itshixa izinto zithembekile, kwaye ifuna ukhe, kodwa design lwabo entsonkothileyo kakhulu ukuzilawula.

Kwinxalenye esezantsi element kumise yi ndiwele yezihlunu apho imvelaphi inyuselwa khona ukuba izindlu ivelufa ibhola esebenzisa of iibheringi mmandla okanye ukunikezela. Izinto eziluncedo semigudu ibhola ziquka benolungelelwano loyilo, ngokusebenza kakhulu lula, ubungakanani encinane, ukuthembeka kunye yengxinano ophezulu, uhlobo olulula flow inxenye, ukungabikho ngokupheleleyo kuso nasiphi na imimandla efile. Ukuze uphendule lo nendwe kufuneka achithe ixesha elifutshane, yaye neevalvu ukuze zisetyenziswe kuzo zonke iintlobo ezingcolisekileyo kwaye viscous ulwelo, slurries kunye slurries, ukumiswa ezahlukeneyo.

Igalelo elibi semigudu ibhola, zibonelelwa ekwakhiweni ngesiphatho console, kuba phambi zone "ufile" imi Ekuveleni, kunye nemodeli ngenkxola-ezifana imvana thabatha kude. Kwemithambo ezipheleleyo Uhlobo wamzalela ukuvula ngokupheleleyo okanye uvale esi sicatshulwa ukutshintsha ibhola ngokwayo. Ukuba ivelufa luvuleleke ngokupheleleyo xa idlula therethrough ukusebenza ilahleko flow fluid ukuba ayikho. Ngokulinganayo phawu elikhulu esi sixhobo ebalulekileyo valving ukwakweli lwemibhobho ephambili inxalenye yomgama.

Ukunciphisa torque kunye nomlinganiselo eziyimfuneko ngexesha kwemithambo zolawulo adla ngokusetyenziswa izivingco iingqameko, ngoko ukuntsonkotha unganciphisa kakhulu ukusetyenziswa kweendlela zobugcisa ..
