I-valve ye-butterfly ephakathi yivalve yokulawula esetyenziswa ngokuqhelekileyo, enokuthi idlale indima ebalulekileyo ekuzinziseni izinga lokuhamba kunye nokulawula uxinzelelo kwinkqubo yolwelo. Ukukhetha uhlobo olufanelekileyo lwevalve yebhabhathane yomgca ophakathi kubaluleke kakhulu ekusebenzeni okuzinzile kwenkqubo. Eli nqaku liza kwazisa umgaqo osisiseko wevalve yebhabhathane ephakathi, kunye nendlela yokukhetha uhlobo oluchanekileyo ngokweemfuno zenkqubo, ukuze kuqinisekiswe ukuzinza kunye nokusebenza kakuhle kwenkqubo yokusebenza.
Okokuqala, umgaqo osisiseko wevalve yebhabhathane ephakathi
Ivalve yebhabhathane yomgca ophakathi yivalve enediski kumzimba wevalve njengenxalenye yokuvala, kwaye ulwelo lulawulwa kwaye luhlengahlengiswe ngokujikeleza idiski. Ulwakhiwo lwayo olusisiseko lubandakanya umzimba wevalve, isiqu sevalve, idiski yevalve njalo njalo. Umzimba wevalvu yeyona ndawo iphambili yevalve kwaye inebhabhathane lokuvuleka lokuhamba kolwelo. I-stem idibanisa i-disc ye-valve kunye nendlela yokusebenza, kwaye ilawula i-on-off kunye nokulawulwa kolwelo ngokujikeleza i-disc valve.
Ivalve yebhabhathane yomgca ophakathi ibonakala ngesakhiwo esilula, ubungakanani obuncinci, ubunzima obulula kunye nokusebenza kakuhle kokulawula ulwelo. Ngenxa yokuba i-disc inokuvulwa ngokupheleleyo, ivalwe ngokupheleleyo kwaye ilungiswe kuyo nayiphi na indawo, i-valve ye-butterfly ephakathi isetyenziswa ngokubanzi kulawulo lokuhamba kunye nokulawula uxinzelelo.
Okwesibini, khetha uhlobo olufanelekileyo lweevalvu zebhabhathane
1. Iimpawu zemidiya ye-Fluid: Imidiya eyahlukeneyo ye-fluid ineemfuno ezahlukeneyo zezinto kunye nokutywinwa kwevalve. Umzekelo, imithombo yeendaba ezonakalisayo kufuneka ikhethe izinto ezikwaziyo ukumelana nomhlwa, imithombo yeendaba yobushushu obuphezulu kufuneka ikhethe izixhobo ezinokumelana nobushushu obuphezulu. Ngoko ke, xa ukhetha uhlobo lwe-valve butterfly, iimpawu ze-fluid medium kufuneka ziqwalaselwe ngokupheleleyo, kwaye izinto ezihambelanayo kunye nesakhiwo sokutywinwa kufuneka sikhethwe.
2. Uxinzelelo olusebenzayo kunye nobushushu: Uxinzelelo olusebenzayo kunye noluhlu lweqondo lokushisa lomgca ophakathi we-butterfly valve nazo ziyizinto eziphambili ekukhethweni. Ngokweemeko ezithile zokusebenza, khetha uhlobo lwe-valve yebhabhathane ephakathi enokumelana noxinzelelo oluhambelanayo kunye nobushushu bokuqinisekisa ukuthembeka kunye nokhuseleko lwevalve.
3. Iimfuno zokuhamba: Misela ubungakanani kunye nefom yendlela yokuhamba yevalve yebhabhathane yomgca osembindini ngokweemfuno zokuhamba kwenkqubo. Kufuneka kuqatshelwe ukuba ukuba izinga lokuhamba kwinkqubo likhulu okanye kukho i-pulsating flow, uhlobo lwe-butterfly valve ye-central line eneempawu ezintle ze-hydrodynamic, ukumelana nokuhamba okuphantsi kunye nengxolo ephantsi kufuneka kukhethwe.
4. Sebenzisa iimeko zokusingqongileyo: Ukuqwalasela indawo yokusetyenziswa kwevalve yebhabhathane yomgca ophakathi, njengokungcangcazela, ukubola, ubushushu obuphezulu kunye nezinye izinto, khetha uhlobo lwevalve yebhabhathane yomgca ophakathi ngokuguquguquka okuhle. Ngaphantsi kweemeko ezikhethekileyo zokusingqongileyo, kuyimfuneko kwakhona ukuqwalasela ukusebenza kokutywinwa kunye nokumelana nokubola kwevalve.
Ezintathu, iintlobo zevalve yebhabhathane yomgca osembindini oqhelekileyo
Ngokweemfuno ezahlukeneyo zenkqubo yolwelo, iintlobo eziqhelekileyo zevalve yebhabhathane ephakathi zezi zilandelayo:
1. Ivalve yebhabhathane ene-eccentric enye: Ivalve yebhabhathane ene-eccentric enye ine-friction ephantsi kunye ne-torque yokuvala, ilungele ulawulo lokuhamba ngokubanzi kunye nolawulo.
2. Ivalve yebhabhathane ene-eccentric ephindwe kabini: Ivalve yebhabhathane eneeccentric ephindwe kabini inokumelana noxinzelelo oluphezulu kunye nokusebenza ngcono kokutywina kunevalve yebhabhathane ene-eccentric enye, efanelekile ngamanye amaxesha aneemfuno zokutywinwa okuphezulu.
3. Ivalve yebhabhathane eneeccentric ezintathu: Ivalve yebhabhathane ene-eccentric iphuhliswa ngakumbi ngesiseko sevalve yebhabhathane ephindwe kabini, enotywino oluphezulu kunye nokumelana nomhlwa, isetyenziswa ngokubanzi kwibango eliphezulu kunye nezihlandlo zokulawula uxinzelelo.
4. Ivalve yebhabhathane yobushushu obuphezulu: ivalve yebhabhathane yobushushu obuphezulu ithatha ubushushu obuphezulu be-alloy imathiriyeli kunye nesakhiwo esikhethekileyo sokutywina, inokusebenza ngokuzinzileyo kwindawo yobushushu obuphezulu, ilungele ukucocwa kweoyile, ishishini lemichiza kunye nezinye iindawo.
5. Ivalve yebhabhathane etyhutyhayo: ivelufa yebhabhathane ipulsating ithatha uyilo olucandekileyo lomjelo wokuqukuqela, olunokunciphisa ifuthe lokuqukuqela kwevalve kunye nokugcina uzinzo lolwelo. Ilungele inkqubo ene-pulsation enkulu yokuhamba.
6. I-valve ye-butterfly yezinto ezikhethekileyo: i-valve ye-butterfly yezinto ezikhethekileyo ifanelekile kumajelo akhethekileyo okanye iimeko ezikhethekileyo zokusebenza, ezifana ne-asidi eqinile, i-alkali eyomeleleyo, igesi ephezulu yokucoca, njl.
Iv. Isishwankathelo
