Ivalve yebhola idla ngokubizwa ngokuba yeyona valve ilula, kodwa ngaba uyazi ngenene?Inomphumela wokujikeleza i-90 degrees.Iplagi yingqukuva enomngxuma ongqukuva okanye umjelo kwi-axis yayo.Kwilizwe lam, iivalve zebhola zisetyenziswa kakhulu ekusulungeni ioli, imibhobho yexesha elide, ishishini lemichiza, iphepha, amayeza, ukugcinwa kwamanzi, umbane, umasipala, intsimbi kunye namanye amashishini, abambe indawo ebalulekileyo kuqoqosho lwelizwe.Eli nqaku ikakhulu lizisa ezinye iimpawu kunye namanqaku okwakhiwa kofakelo lwevalve yebhola yeplastiki.
Ukusebenza okusisiseko
Ivalve yebhola yeplastiki isetyenziselwa ukunqumla okanye ukudibanisa okuphakathi kumbhobho, kwaye iifom ezikhethekileyo zingasetyenziselwa ukulawulwa kwamanzi kunye nokulawula.Xa kuthelekiswa nezinye iivalve, ivalve yebhola ineempawu zesakhiwo esilula, umthamo omncinci, ubunzima obukhanyayo, ukusetyenziswa kwezinto ezincinci, ubungakanani obuncinci bokufaka, ukutshintshela ngokukhawuleza, i-90 ° ukujikeleza kwakhona, umzuzu omncinci wokuqhuba, kunye nezinye iimpawu.Ineempawu ezilungileyo zokulawula ulwelo kunye nokusebenza kokutywinwa okuvaliweyo.
Kwiminyaka yakutshanje, ngokuhambelana neemfuno zamanye amashishini kumashishini ahlukeneyo, kuye kwaphuhliswa iindidi zeevalvu zeplastiki, ezinomsebenzi obalaseleyo.Ukuthatha ivalve yebhola ye-UPVC njengomzekelo, xa kuthelekiswa nevalve yebhola yentsimbi, ubunzima bomzimba wevalve, ukumelana nokugqwala okuqinileyo, inkangeleko ehlangeneyo kunye nentle, ubunzima obulula, ukufakwa okufanelekileyo, ukuxhathisa okuqinileyo kwe-corrosion, uluhlu olubanzi olusebenzayo, ukucoceka kwezinto kunye nokungabikho. -ityhefu, ukuxhathisa ukunxiba, kulula ukunxiba, kulula Ukuqina kwaye uyisebenzisele ukugcinwa lula.Ukongeza kwizinto zeplastiki ze-UPVC, i-valve yebhola yeplastiki nayo ine-FRPP, i-PVDF, i-PPH, i-CPVC, njl. Izakhiwo zayo ikakhulu ziquka ilifa, i-spiral flang, njl.

Ukuhlohla
Amanqaku okufakela ulwakhiwo: 1. Indawo, ubude, kunye nesalathiso sokungeniswa kunye nokuthunyelwa ngaphandle kufuneka kuhlangabezane neemfuno zoyilo, kwaye uqhagamshelo luqinile kwaye luqinile.2. Izibambo zevalvu ezahlukahlukeneyo ezifakwe kumbhobho wokugquma we-thermal akufuneki zibe phantsi.Ntathu.Ngokuxhomekeke kwiimfuno zoyilo lombhobho, iipads zifakwe phakathi kwe-valve flange kunye ne-pipeline flange.Isine.Ngaphambi kokuba i-valve ifakwe, kufuneka iqwalaselwe ukuqinisekisa ukuba ngaba umenzi uye wafumana uvavanyo loxinzelelo.
Ivalve yebhola yeplastiki isetyenziswa njengevalve yebhola iyonke, enamanqaku okuvuza amancinci, amandla aphezulu, kwaye kulula ukudibanisa ivalve yebhola ukuyifaka kunye nokuqhaqha.Ukufakwa kunye nokusetyenziswa kwevalve yebhola: Xa ii-flanges ziphela zidibene nombhobho, i-bolt kufuneka iqiniswe ngokulinganayo ukukhusela i-deformation ye-flange kunye nokuvuza.Jika isibambo ngokwewotshi ukuze ucime, kungenjalo siya kuvulwa.Iivalve zebhola eziqhelekileyo zingasetyenziselwa kuphela ukusika kunye nokuhamba, kwaye azikwazi ukusetyenziselwa ukulungiswa kwezithuthi.Ulwelo olunamasuntswana aqinileyo kulula ukukrwela umphezulu webhola.Apha, kufuneka sichaze ukuba kutheni iivalve zebhola eziqhelekileyo azifanelekanga ukulungiswa kwezithuthi, kuba ukuba i-valve ikwimeko evulekileyo ixesha elide, ubomi benkonzo yevalve buya kuncitshiswa.Isizathu simi ngolu hlobo lulandelayo: 1. Ukutywinwa kweValve kunokonakala.Ibhola iya konakaliswa;3. Ulungelelwaniso lokuhamba aluchanekanga.Ukuba umbhobho ngumbhobho wobushushu obuphezulu, kulula ukubangela i-eccentricity.
