Iivalvu ze-slab zizinto ezibalulekileyo kwiinkqubo ezahlukeneyo zemizi-mveliso, ngakumbi ezo zibandakanya ukulawula ukuhamba kolwelo okanye iigesi.Ezi zivalo zisetyenziswa kwizicelo ezininzi ezahlukeneyo, kubandakanywa ukuveliswa kweoli kunye negesi, ukusetyenzwa kweekhemikhali, kunye nonyango lwamanzi.Kweli nqaku, siza kuphonononga ukuba zeziphi iivalve ze-slab, zisebenza njani, kunye neentlobo zazo ezahlukeneyo.
Yintoni naivalve ye-slab?
Ivalve yesilabhu luhlobo lwesivalo esinesango elisicaba okanye elimile okwe slab elityibilika linyuka lize lilawule ukuhamba kolwelo okanye igesi ngombhobho.Isango ngokuqhelekileyo lenziwe ngentsimbi kwaye liqhutywa yi-actuator, enokuthi ibe yi-manual, i-hydraulic, okanye i-pneumatic.Xa isango likwindawo evaliweyo, livala ukuhamba kolwelo, kwaye xa livuliwe, livumela ulwelo ukuba ludlule.
Wenza njani aivalve ye-slabumsebenzi?
Umgaqo osebenzayo wevalve ye-slab ulula.Xa i-actuator ivuliwe, ihambisa isango phezulu okanye ezantsi, kuxhomekeke ekubeni ivalve kufuneka ivulwe okanye ivalwe.Kwindawo evaliweyo, isango livaleka kumzimba wevalvu, lidala itywina eliqinileyo elithintela ulwelo ukuba lungahambi kumbhobho.Xa ivalve kufuneka ivulwe, i-actuator isusa isango endleleni, ivumela ulwelo ukuba luhambe ngokukhululekileyo kumbhobho.
Iivalve zeslab ziqhele ukusetyenziswa kwizicelo apho umthamo omkhulu wolwelo kufuneka uhanjiswe ngokukhawuleza.Ziyincedo ngokukodwa kwizicelo apho i-fluid i-abrasive okanye i-corrosive, njengoko isango lingenziwa ngezinto ezichasene nokugqoka kunye nokukrazula.
Iintlobo zeevalvu ze-slab
Kukho iintlobo ngeentlobo zeevalvu ze-slab, nganye inoyilo olukhethekileyo kunye neempawu zokusebenza.Ezinye zezona ntlobo zixhaphakileyo ziquka:
Ivalve ye-slab stem enyukayo: Olu hlobo lwevalve ye-slab inesango elihla linyuka lihamba nesiqu esinemisonto.Njengoko isiqu sijikelezwa, isango lihamba phezulu okanye lihla, livula okanye livale ivalve.
Ivalve ye-slab ye-stem enganyukiyo: Olu hlobo lwesivalo lunesango elinyuka lisihla kunye nesiqu esingenamisonto.Esikhundleni sokujikeleza isiqu, i-actuator ihambisa isango phezulu okanye phantsi ngokuthe ngqo, ivula okanye ivale ivalve.
Ivalve yesango lemela: Olu hlobo lwesivalo lunesango elibukhali elinqumla ulwelo njengoko lunyuka lusehla.Izivalo zesango lemela zidla ngokusetyenziswa kwizicelo apho ulwelo lunamasuntswana aqinileyo, njengasemigodini okanye kunyango lwamanzi amdaka.
Ivalve yesango lokutyibilika: Olu hlobo lwesivalo lunesango elijikela emva naphambili kunokuba linyuke lihle.Iivalvu zesango lokutyibilika zidla ngokusetyenziswa kwizicelo apho kufuneka isitywina esiqinileyo, njengakwimibhobho yerhasi.
Ivalve yesango leWedge: Olu hlobo lwesivalo lunesango elimise okwe wedge.Njengoko isango lithotywa, licinezela isitulo sevalvu, lisenza itywina eliqinileyo elithintela ulwelo ukuba lungangeni.
Ukukhetha ivalve ye-slab efanelekileyo kwisicelo sakho
Xa ukhetha i-valve ye-slab kwisicelo sakho, kukho izinto ezininzi ekufuneka uziqwalasele, kubandakanywa uhlobo lolwelo oluthuthwayo, uxinzelelo kunye nobushushu bolwelo, kunye nesantya sokuhamba.Kubalulekile ukukhetha ivalve eyenziwe kwizinto ezihambelana nolwelo oluthuthwayo, kunye nevalve enokumelana noxinzelelo kunye nobushushu bolwelo.
Ukongeza, kubalulekile ukukhetha ivalve elingana ngokufanelekileyo kwisicelo sakho.Ukukhetha i-valve encinci kakhulu kunokubangela ukuhla koxinzelelo olugqithisileyo kunye nezithintelo zokuhamba, ngelixa ukhetha i-valve enkulu kakhulu kunokubangela ukunyuka kweendleko kunye nokunciphisa ukusebenza kakuhle.
Ukuqukumbela
Iivalve zeslabngamacandelo ayimfuneko kwiinkqubo ezininzi zemizi-mveliso, ebonelela ngolawulo oluchanekileyo lokuhamba kolwelo ngemibhobho.Ngoyilo lwazo olulula kunye nokusebenza okuthembekileyo, iivalve ze-slab zilungele ukusetyenziswa kuluhlu olubanzi lwezicelo, ukusuka kwimveliso yeoli kunye negesi ukuya.
ukusetyenzwa kweekhemikhali kunye nokunyangwa kwamanzi.Ngokuqonda iintlobo ezahlukeneyo zeevalve ze-slab kunye nezinto ezinokuthi ziqwalaselwe xa ukhetha i-valve efanelekileyo kwisicelo sakho, unokuqinisekisa ukuba inkqubo yakho iqhuba kakuhle kwaye ngokufanelekileyo.
Kwakhona kubalulekile ukugcina ngokufanelekileyo iivalvu zakho ze-slab ukuqinisekisa ukusebenza kwazo okuqhubekayo kunye nokuthembeka.Ukuhlolwa rhoqo kunye nokugcinwa kunokunceda ukuchonga nayiphi na imiba enokubakho ngaphambi kokuba ibe yingxaki ebalulekileyo, ukuthintela ixesha lokunciphisa kunye nokulungiswa kweendleko.
Ukuqukumbela, iivalve ze-slab ziyinxalenye yeenkqubo ezininzi zoshishino, ezibonelela ngolawulo oluthembekileyo noluchanekileyo lokuhamba kwamanzi.Ngokukhetha i-valve efanelekileyo kwisicelo sakho kwaye uyigcine ngokufanelekileyo, unokuqinisekisa ukuba inkqubo yakho ihamba kakuhle kwaye isebenze kakuhle, ukwandisa imveliso kunye nokunciphisa ixesha lokuphumla.
