Ukuhlaziya okubili okukhulu kweuvemvane valveamaphuzu okufaka: indawo yokufaka, ubude, kanye nesiqondiso se-inlet ne-outlet kumele kuhlangabezane nezidingo zokuklama.Qaphela ukuthi isiqondiso sokugeleza okuphakathi kufanele sihambisane nesiqondiso somcibisholo omakwe emzimbeni we-valve, futhi uxhumano kufanele luqine futhi luqine.I-valve uvemvane kufanele ihlolwe ngokubonakalayo ngaphambi kokufakwa, futhi i-nameplate yevalvu kufanele ihambisane nezinga likazwelonke lamanje elithi “General Valve Mark” GB12220.Kumavalvu anomfutho wokusebenza omkhulu kuno-1.0MPa kanye nomsebenzi wokunqamula epayipini elikhulu, ukuhlolwa kwamandla nokuqina kufanele kwenziwe ngaphambi kokufakwa.Ingasetshenziswa ngemuva kokuqeqeshwa.Ngesikhathi sokuhlolwa kwamandla, ingcindezi yokuhlola iphindwe izikhathi ezingu-1.5 ingcindezi encane, futhi ubude besikhathi abukho ngaphansi kwemizuzu emi-5.Izindlu ze-valve kanye nokupakishwa kufanele zifaneleke ngaphandle kokuvuza.I-valve ye-Butterfly ingahlukaniswa ngohlobo lwepuleti ye-offset, uhlobo lwepuleti eqondile, uhlobo lwepuleti ethambekele kanye nohlobo lwe-lever ngokusho kwesakhiwo.Ngokwefomu lokubeka uphawu, lingahlukaniswa ngohlobo oluthambile lokuvala kanye nohlobo lokuvala okunzima.Uhlobo lophawu oluthambile luvamise ukuvalwa ngendandatho yerabha, futhi uhlobo lophawu oluqinile luvamise ukuvalwa ngendandatho yensimbi.
Umgomo wesakhiwo se-Butterfly valve:
Ivalve uvemvane ngokuvamile yakhiwa i-angular stroke actuator (0~90° ukuzungezisa ngokwengxenye) kanye nevalve uvemvane iyonke ngoxhumo lwemishini, ngemva kokufakwa nokulungisa iphutha.Ngokwemodi yesenzo, kukhona: uhlobo lokushintsha kanye nohlobo lokulungisa.Uhlobo lweswishi ukuxhuma ngokuqondile ukunikezwa kwamandla (AC220V noma okunye ukunikezwa kwamandla kwezinga lamandla) ukuze uqedele isenzo sokushintsha ngokushintsha izikhombisi-ndlela zokuya phambili nokuhlehla.Uhlobo lokulungiswa luxhaswe amandla kagesi we-AC220V, futhi luthola inani lepharamitha elisethiwe 4~20mA (0~5 kanye nezinye izilawuli zamanje ezibuthakathaka) zesistimu yokulawula ezishintshayo zezimboni ukuze kuqedelwe isenzo sokulungisa.
Izinhlelo zokusebenza ze-Butterfly valve:
Ama-valve e-butterfly afanele ukulawulwa kokugeleza.Njengoba ukuncipha komfutho we-valve uvemvane epayipini kukhulu uma kuqhathaniswa, ukuqina kwepuleti uvemvane ukuze limelane nokucindezela komzila wepayipi kufanele futhi kucatshangelwe lapho livaliwe.Ngaphezu kwalokho, imikhawulo yokushisa yokusebenza kwempahla yesihlalo se-elastomeric emazingeni okushisa aphakeme nawo kufanele icatshangelwe.Ubude besakhiwo nokuphakama okuphelele kwe-valve uvemvane kuncane, isivinini sokuvula nokuvala siyashesha, futhi sinezici ezinhle zokulawula uketshezi.Isimiso se-valve ye-butterfly ifaneleka kakhulu ekwenzeni ama-valve amakhulu.Lapho i-valve ye-butterfly idingeka ukuthi isetshenziselwe ukulawula ukugeleza, into ebaluleke kakhulu ukukhetha kahle ubukhulu kanye nohlobo lwe-valve butterfly ukuze lusebenze kahle nangempumelelo.
I-Butterfly valve ilungele amanzi ahlanzekile, indle, amanzi olwandle, amanzi anosawoti, umusi, igesi yemvelo, ukudla, imithi, uwoyela kanye nama-acids ahlukahlukene adinga ukubekwa uphawu, ukuvuza kwe-zero ekuhlolweni kwegesi, isikhathi eside sokuphila, kanye nezinga lokushisa eliphakathi -10 degrees. futhi 150 degrees.I-alkali namanye amapayipi.
