Isebenza Njani Ivalufa Yebhabhathane eZimeleyo?

Jonga umfanekiso oMkhulu
Enye yeevalvu ezisetyenziswa ngokuqhelekileyo kwinkqubo yokubhobhoza.Ilungu lentsapho yekota, iivalve zebhabhathane zihamba ngentshukumo ejikelezayo.I-disc yevalve yebhabhathane ifakwe kwisiqu esijikelezayo.Xa ivuliwe ngokupheleleyo, i-disc ikwi-angle ye-90-degree malunga ne-actuator yayo.Le valve ifanele ukuhamba okukhulu kunye noxinzelelo oluphantsi kunye nemidiya ye-viscous enepesenti enkulu eqinile.

Iimpawu zevalve yebhabhathane ziquka:
– Ukuvula okulula
– Kulula ukuyifaka
– Kulula ukuyigcina
– Kungabizi ukuyifaka
-Ifuna indawo encinci
– Iindleko zokulungisa ezisezantsi
-Ifanele ukusetyenziswa kwevalvu enkulu

Enye indlela yokwahlulahlula iivalvu zebhabhathane isekelwe kuyilo lwesitulo.Olunye lolo yilo sisitulo esomeleleyo.Oko sele kutshiwo, eli nqaku liphengulula nzulu kwindlela ivalve yebhabhathane ekwaziyo ukumelana nayo.Ikwajongana nomahluko phakathi kwevalve yebhabhathane ehleli ngentsimbi kunye nevalve yesitulo esomeleleyo sebhabhathane.

Iindidi zeeVavu zebhabhathane

Njengoko bekutshiwo ngaphambili, iivalve zebhabhathane zihlelwa ngeendlela ezininzi.Icandelo ngalinye lisebenza kakuhle kunye nezicelo ezithile.Ekubeni kukho ngaphezu kwendlela enye yokuhlela iivalvu, unokwenza iivalve zebhabhathane ngokuxhomekeke kukhetho lwakho kunye nesicelo.

Iivalvu zebhabhathane ngohlobo loQhagamshelwano

Olu lwahlulo lusekelwe kwindlela i-valve exhunywe ngayo kwimibhobho.

Uhlobo lweWafer

Le yeyona nto inoqoqosho kwaye ilula.Olu yilo lujolise ekuthinteleni uxinzelelo lwe-bi-directional umahluko kunye nokubuyela umva.Kukho iiflange ezimbini zemibhobho ezidibanisa ivalve.Batywina kwaye badibanise i-valve kwinkqubo yombhobho ngokusebenzisa iibholiti.Ukutywinwa okunamandla, kukho i-O-rings kunye neegaskets ezibekwe kumacala omabini evalve.

Uhlobo lweLug

Ivalve yebhabhathane yohlobo lwelug ineelugi ezibekwe ngaphandle kwaye zijikeleze umzimba wevalvu.Ezi zidla ngokusetyenziswa kwiinkonzo zokuphela okanye kwizicelo ezifuna kuphela uxinzelelo oluphantsi.Iilugs zifakwe umsonto.Iibholiti, ezihambelana naloo mibhobho, zidibanisa i-valve kumbhobho.

Impundu-Welded

Ivalve yebhabhathane ene-butt-welded inemidibaniso edityaniswe ngokuthe ngqo kumbhobho.Olu hlobo lwevalve lusetyenziswa ikakhulu kwizicelo zoxinzelelo oluphezulu.

Flanged

Olu hlobo lubonakaliswe ngokuba nobuso be-flange kumacala omabini.Kulapho iivalve zidibana khona.Olu luyilo luqhelekileyo phakathi kweevalve ezinobungakanani obukhulu.

Iivalvu zeButterfly ngohlobo loLungelelwaniso lweDisc

Olu hlobo lokuhlela lusekelwe kuyilo lwesihlalo kunye ne-angle apho isihlalo sifakwe kwi-disc.

Ugxininise

Olu lolona yilo lusisiseko phakathi kwabo baqukiweyo kolu lwahlulo.Oku kukwabizwa ngokuba yivalve yebhabhathane ekwaziyo ukuhlala okanye ngamanye amaxesha uyilo lwevalve yebhabhathane engu-zero-offset.Isiqu sidlula embindini wediski kunye nesihlalo.Isihlalo sifumaneka kwi-diameter yangaphakathi yomzimba.Amaxesha amaninzi, iivalve ezihleliyo ezithambileyo zifuna uyilo olugxininisiweyo.

Iseti ephindwe kabini

Ngamanye amaxesha oku kubizwa ngokuba yi-double eccentric butterfly valve.I-disc ayihambelani neziko lomzimba kunye ne-valve yonke.Oku kushenxisa isihlalo ngaphandle kwesitywina ngexesha lokusebenza.Lo matshini unciphisa impembelelo yokukhuhlana kwidiski yebhabhathane.

I-Offset kathathu

Ivalve yebhabhathane kathathu yaziwa ngokuba yi-triple eccentric butterfly valve.Umphezulu wesihlalo wenza enye i-offset.Olu luyilo luqinisekisa ukuhamba okungahambiyo kwediski ngexesha lokusebenza.Oku kuqhelekileyo xa izihlalo zenziwe ngentsimbi.

Umsebenzi weValve yebhabhathane

Iivalve zebhabhathane zezinye zezo zivalo ezinokuthi zisetyenziswe ekubetheni nasekuvaleni okanye ukuvala.Iyakwazi ukumodareyitha isixa okanye ukuhamba kwemidiya edlula kwivalve kumsebenzi onikiweyo.Ngokubhekiselele kwindlela yokuvala okuqinileyo, kufuneka uthathele ingqalelo ubungakanani bomgca kunye nokuhla koxinzelelo oluphantsi olufunekayo xa ivalve ivuliwe.

Ukuba ivelufa yokulawula, ivalve yebhabhathane idinga izibalo ezithile kunye nesibonelelo kwiimfuno zemidiya kunye nezibalo ezinjengeemfuno zokuhamba, ukuhla koxinzelelo, kunye nezinto ezithandwayo.

Isebenza njani iValve yebhabhathane eZimeleyo

Ivalve yebhabhathane eyomelelayo ehleliyo ibonakala ngesiqu esibotshwe kwidiski kwaye sincanyathiselwe emazantsi evalve.Amaxesha amaninzi, izihlalo zolu hlobo lwevalvu zenziwe ngerabha, ngoko ke, igama elithi resilient.
Ngaloo ndlela, i-disc ixhomekeke kwikhono eliphezulu lokuqhagamshelana nesihlalo kunye nesihlalo sokuvalwa okuqinileyo.Ngolu hlobo loyilo, unxibelelwano lwesihlalo-ukuya-kutywina luqala malunga nokujika kwe-85-degree.

Iivalve zebhabhathane ezihleliyo ezihlala zihleli zenziwe ngeqhekeza elinye.Oku kwandisa amandla evalve kunye nokunciphisa ubunzima bayo.Isitulo serabha ngasemva senza kube lula ukuyifaka naxa ivalve yebhabhathane ingaphandle.Ngenxa yobume bezinto eziphathekayo, unamandla okutywinwa okuthembekileyo.

Ukuze isihlalo sitywine ngokufanelekileyo, kufuneka singene ngokuqinileyo kwaye sithintele umda wediski.Oku kwenza idiskhi yebhabhathane ingabi nakushukuma.Oku ke kumisa ukuhamba.Enye indlela yokuyijonga yi-disc isebenza kwisihlalo esikumlinganiselo ongaphakathi wevalve.

Isixhobo sokuXhobisa seSitulo seBhavaveyi

Izihlalo zevalve yebhabhathane zingahlelwa zibe zimbini.Ezi zixhobo ezithambileyo kunye nevalve yebhabhathane ehleli ngentsimbi.Ivalve yesitulo sebhabhathane eyomelelayo yeyangaphambili.Isetyenziselwa izicelo ezingabalulekanga, izihlalo ezinjalo zebhabhathane zingenziwa kwi-EPDM (ethylene propylene diene terpolymer), i-VITON, kunye ne-acrylonitrile-butadiene irabha.

Umahluko phakathi kweeValuvu zeBhavane ezihleli ngesinyithi kunye neeValuvu zebhabhathane eziZimeleyo

Iivalvu zebhabhathane ezihleliyo okanye ezo zigxininise zihlala zihlala phantsi.Xa kuthelekiswa, i-eccentric okanye ezo zine-offsets, zenziwe ngezihlalo zetsimbi, ngaphandle koyilo oluphindwe kabini.Oku kunokuba nezinto ezihlala phantsi okanye isinyithi.Ngokuchaseneyo noyilo oluphindwe kabini, uyilo lwevalvu egxininisiweyo luxabiso eliphantsi.

Ukuvalwa okuqinileyo, kuhlala kukho isibonelelo semigangatho yeentsimbi ezihleli iivalve zebhabhathane.Kwelinye icala, ihlala inguziro ukuvuza kwevalve yebhabhathane eyomelelayo ehleliyo, ngaphandle kokuba isihlalo sonakalisiwe.

Kwakhona, kunye noyilo lwesihlalo esomeleleyo, iivalvu zebhabhathane ezinjalo zixolela ngakumbi kumajelo ashinyene kakhulu.Nokuba yeyiphi na inkunkuma ebanjwe phakathi kwezixhobo zevalve, isihlalo sisenokubonelela ngokuqina kwetywina.Kwakhona kulula ukubuyisela izihlalo ezithambileyo xa kuthelekiswa nezihlalo zentsimbi ukuba ezi zinokukhubazeka.Nangona kunjalo, kuyilo lwesihlalo sesinyithi, izihlalo zinokuxinga kwindawo ukuba kukho inkunkuma phakathi kwezixhobo zevalvu yangaphakathi.
