I-Butterfly Valve, ekwabizwa ngokuba yiValve yeFlepu, yivali elawulayo enesakhiwo esilula. Iivallo zebhabhathane zingasetyenziselwa ukutshintsha ulawulo lwemithombo yoxinzelelo esezantsi. Ivalve yebhabhathane isebenzisa i-disc okanye ipleyiti yebhabhathane njenge-disc, ejikeleza i-vall ye valve ukuze ivulwe kwaye isondele.
Iivallo zebhabhathane zinokusetyenziselwa ukulawula ukuhamba kweentlobo ezahlukeneyo zolwelo ezinjengomoya, amanzi, umsasazi wemidiya yobutyebi, udaka, ioyile, i-oyile, i-oyile, i-oyile ye-oyile kunye ne-radio medions kunye neendaba zentsimbi. Ibizana ikakhulu idlala indima yokusika kunye nokuqaqamba kumbhobho. Inxalenye yokuvula kunye nokuvala i-vaterfely ivalve ifakwe ipleyiti yebhabhathane ejikeleza i-axis yayo kwibhunga lokuvula kunye nokuvalwa.
Iimpawu eziphambili zevalve yebhabhathane zezi: i-torque encinci esebenzayo, indawo encinci yokufakelwa kunye nobunzima bokukhanya. Ukuthatha i-DN1000 Umzekelo, ivalve yebhabhathane imalunga ne-2 t, ngelixa i-valve yesango imalunga ne-3.5 t, kwaye ivalve yebhabhathane kulula ukudibanisa nezixhobo eziphezulu kwaye zinokuqiniseka kakuhle. Ukungancedisi kwivalve etywiniweyo yerabha yeyokuba xa isetyenziselwa ukuqaqamba, i-cavication iyakwenzeka ngenxa yokusetyenziswa okungafanelekanga, okuya kubangela i-Peeling kunye nomonakalo weSitulo serabha, ukuze ukhethe ngokuchanekileyo kwimfuno yeemeko zomsebenzi. Ubudlelwane phakathi kokuvulwa kwevalve yebhabhathane kunye nereyithi yokuhamba ngokusisiseko itshintsha umgca. Ukuba isetyenziselwa ukulawula ukuhamba, iimpawu zayo zokuhamba zihambelana ngokusondeleyo nokunganyangeki kwendlela yokuhamba. Umzekelo, ukuba imibhobho emibini ifakwe kwindawo enye ye-valve kunye nefom, kodwa ilahleko yelahleko yahlukile, inqanaba lokuhamba kweeValve liya kwahluka kakhulu. Ukuba i-valve ikwimo ye-hertling enkulu, i-cavication ithathelwe ukuba ifike ngasemva kweplate ye-valve, enokwenzakalisa ivalve. Ngokubanzi, isetyenziswa ngaphandle kwe-15 °. Xa ivalve yebhabhathane ikwindawo yokuvula ephakathi, imilo evulekileyo eyenziwa ngumzimba wevali kunye nomphambili weplate yebhabhathane igxile kwi-vall, kwaye la macala mabini abumba amazwe ahlukileyo. Isiphelo sangaphambili seplate yebhabhathane kwelinye icala lihamba ecaleni kwendlela yokuqhuba amanzi, kwaye elinye icala lihamba ecaleni kwendlela yokuqukwa kwamanzi. Ke ngoko, elinye icala le-valir kunye neplati ye-valve yenza i-valve-ivule i-nozzle-ivale, kwaye elinye icala liyafana nokuvulwa okubuhlungu. I-velocity yendawo yokuhamba ecaleni kwe-nozzle ihamba ngokukhawuleza kunokuba kwicala elingaphantsi, kwaye uxinzelelo olubi luya kwenziwa phantsi kwevali kwithayile, ngokufuthi itywina lerabha liza kuphuma. I-torque esebenzayo ye-butterfly ivelve iyahluka ngokuvula kunye nokuvula nokuvalwa kwevali. Kwiivali zebhabhathane ezithe tyaba, ngakumbi iivasta ezinkulu zedayam, ngenxa yobunzulu bamanzi, i-torque iveliswe ngumahluko phakathi kweentloko eziphezulu ze-valve zingenakutyeshelwa. Ukongeza, xa i-elbow ifakwe kwindawo yokungena kwivalve, ukuhamba kwekhefu kwaye itota iya kukhula. Xa ivalve ikwindawo yokuvula ephakathi, indlela yokusebenza kufuneka ibe kukuzilalela ngenxa yesenzo sokuhamba kwamanzi.
I-Butterfly Valve luhlobo lwe-valve esebenzisa ukuvula i-disc kunye necandelo lokuvala ukubuyela umva nangaphandle kwe-90 ° ukuvula, ukusondela okanye ukulungisa ukuhamba kwephakathi. Ivali yebhabhathane ayinalo kuphela ulwakhiwo olulula, ubungakanani obukhulu, ubunzima bokukhanya, ubungakanani obuphantsi, ubungakanani bofakelo oluncinci, olulula kwaye lusebenza ngokukhawuleza, kodwa lube nokuvalwa kunye nokutywina iimpawu ezifanayo. Enye yezona ntlobo zeValte zeHalve. I-vally yebhabhathane isetyenziswa. Iintlobo kunye nenani lokusetyenziswa kwayo zisasanda, kwaye ikhula kubushushu obuphezulu, uxinzelelo oluphezulu, ukutywinwa okukhulu, ukutywina okuphezulu, iimpawu ezibalaseleyo, kunye nomsebenzi weva-valti. Ukuthembeka kwayo kunye nezinye izalathi zomsebenzi kufikelele kwinqanaba eliphezulu.
Ivalve yebhabhathane ihlala ingaphantsi kwe-90 ° ukusuka ekuvulekeni ngokupheleleyo ekuvalekeni ngokupheleleyo. Ibhodlo yebhabhathane kunye nebhabhathane le-byterfly alinasikhono sokuzikhethela. Ukuze ubeke iplate yebhabhathane, i-Worm yeGem yeGera ifakwe kwi-valve rod. Ukusetyenziswa kwe-Worm Geardy Scress ayikwenzi ipleyiti yebhabhathane ukuba ibekhona ngokwakho, yenza iplate yebhabhathane iyeke nakweyiphi na indawo, kodwa ikwaphucula ukusebenza kwevali. Iimpawu ze-Buttervery ye-Butterfely ye-Butterfely: Ukuxhathisa ubushushu obuphezulu, ububanzi be-valve ye-valve, i-vall ye-valve yenziwe ngentsimbi ye-carbon, kwaye i-varing ye-vate ye-valve yenziwa ngomsesane wesinyithi. I-valves enkulu ephezulu ye-blackffily yenziwa ziipleyiti zentsimbi ze-welding kwaye isetyenziselwa ikakhulu kwii-ducts zegesi kunye nemibhobho yegesi kwimithombo yeendlela zobushushu eziphezulu.
