1. Iimpawu zesakhiwo
Kukho umahluko ocacileyo phakathi kwevalve yebhabhathane yodidi A kunye nevalve yebhabhathane yodidi B ngokwesakhiwo.
1.1 Udidi A iivalve zebhabhathane luhlobo "concentric", ludla ngokuba nesakhiwo esilula, esibandakanya umzimba wevalvu, idiski yevalvu, isitulo sevalvu, ishafu yevalvu kunye nesixhobo sokuhambisa. Idiskhi yevalve imile okwediskhi kwaye ijikeleza kwishafu yevalve ukulawula ukuhamba kolwelo.
1.2 Ngokwahlukileyo, i-valve ye-butterfly yodidi lwe-B luhlobo lwe-"offset", oku kuthetha ukuba i-shaft ikhutshwe kwi-disc, iyinkimbinkimbi kwaye ingaba neempawu ezongezelelweyo, izixhaso, okanye ezinye izinto ezisebenzayo zokubonelela ngokutywinwa okukhulu kunye nokuzinza.
2. Aizicelo kwiimeko ezahlukeneyo zokusebenza
Ngenxa yokumahluko kulwakhiwo, udidi A lwevalve yebhabhathane kunye nodidi B lwevalve yebhabhathane nazo zisetyenziswa kwiimeko ezahlukeneyo zokusebenza.
2.1 Udidi A iivalvu zebhabhathane zisetyenziswa kakhulu kuxinzelelo oluphantsi, isixokelelwano sombhobho omkhulu wedayamitha enkulu, njengokukhupha amanzi, ukungena komoya kunye namanye amashishini, ngenxa yobume bayo obulula, ubungakanani obuncinci, ubunzima bokukhanya kunye nezinye iimpawu.
2.2 I-valve ye-butterfly yeCandelo B ifaneleke ngakumbi kwisicelo sokusebenza kunye neemfuno zokusebenza zokutywinwa okuphezulu kunye noxinzelelo olukhulu oluphakathi, olufana neekhemikhali, i-petroli, igesi yendalo kunye namanye amashishini.
3. Uthelekiso lwenzuzo yokusebenza
3.1 Ukusebenza kokutywina: Iivalvu zebhabhathane zodidi B zingcono kunevalufa zebhabhathane zodidi A ekusebenzeni kokutywina, ngenxa yolwakhiwo lwazo oluntsonkothileyo kunye noyilo olongezelelweyo lokutywina. Oku kwenza ukuba i-valve yebhabhathane yecandelo B igcine isiphumo esihle sokutywinwa kwiindawo ezirhabaxa ezifana noxinzelelo oluphezulu kunye nobushushu obuphezulu.
3.2 Umthamo wokuqukuqela: Umthamo wokuqukuqela wodidi Ivalve yebhabhathane yomelele, kuba uyilo lwediski yevalve lulula, ukuxhathisa kokudlula kolwelo kuncinci. Ivalve yebhabhathane yodidi B inokuchaphazela ukusebenza kakuhle kolwelo ukuya kumlinganiselo othile ngenxa yobume bayo obuntsonkothileyo.
3.3 Ukuqina: Ukuqina kodidi lwe-butterfly valves luhlala luphezulu, kuba uyilo lwalo lwesakhiwo kunye nokukhethwa kwezinto eziphathekayo kunika ingqalelo ngakumbi ukuzinza kwexesha elide kunye nokuxhathisa ukubola. Nangona i-valve ye-butterfly ilula kwisakhiwo, inokuba yingozi kakhulu ukutshabalalisa kwiindawo ezithile ezinzima.
4. Ukuthenga amanyathelo okhuseleko
Xa kuthengwa udidi A kunye nodidi B izivalo butterfly, ezi zinto zilandelayo kufuneka kuthathelwe ingqalelo:
4.1 Iimeko zokusebenza: Khetha udidi olufanelekileyo lwevalve yebhabhathane ngokoxinzelelo lwabo lokusebenza, ubushushu, ubuphakathi kunye nezinye iimeko zesixokelelwano sombhobho. Ngokomzekelo, i-valve ye-butterfly yodidi kufuneka inikwe kuqala kuxinzelelo oluphezulu kunye neendawo zokushisa eziphezulu.
4.2 Iimfuno zokusebenza: Iimfuno zokusebenza ezicacileyo, ezifunekayo ukuvulwa nokuvala ngokukhawuleza, ukusebenza rhoqo njl., Ukukhetha isakhiwo esifanelekileyo sevalve yebhabhathane kunye nemo yokuhambisa.
4.3 Uqoqosho: Phantsi kwesiseko sokuhlangabezana neemfuno zokusebenza, qwalasela uqoqosho lwevalve yebhabhathane, kubandakanywa iindleko zokuthenga, iindleko zokugcina, njl. njl., iivalve zebhabhathane zodidi A zihlala ziphantsi ngexabiso, ngelixa izivalo zebhabhathane zodidi B, nangona zingcono ukusebenza, kusenokuba phezulu ngokwentelekiso ixabiso.
