Enyanisweni, i-valve yokulawula umbane isetyenziswe ngokubanzi kwishishini kunye nemigodi.Ivalve yokulawula ibhola yombane idla ngokuqulunqwa nge-angular stroke actuator yombane kunye nevalve yebhabhathane ngokuqhagamshelwa koomatshini, emva kofakelo kunye nokulungiswa kweempazamo.Ivalve yebhola yokulawula umbane ngokwendlela yokwenza isenzo: uhlobo lokutshintsha kunye nohlobo lommiselo.Oku kulandelayo yinkcazo eyongezelelweyo yevalve yokulawula ibhola yombane.
Kukho iingongoma ezimbini eziphambili ekufakweni kwevalve yokulawula ibhola yombane
I-1) Indawo yokufakela, ukuphakama kunye nolwalathiso lwe-inlet kunye ne-outlet kufuneka ihlangabezane neemfuno zoyilo.Isalathiso sokuhamba okuphakathi siya kuhambelana necala lotolo oluphawulwe kumzimba wevalvu, kwaye umdibaniso uya kuqina kwaye uqine.
2) Ngaphambi kokufakwa kwevalve yolawulo lombane, ukuhlolwa kwembonakalo kufuneka kuqhutywe, kwaye ipleyiti yegama levalve iya kuhambelana nomgangatho wangoku wesizwe "uphawu lwevalve yezandla" GB 12220. Kwivalve enoxinzelelo lokusebenza olukhulu kune-1.0 MPa kunye nomsebenzi wokunqunyulwa kumbhobho oyintloko, uvavanyo lwamandla kunye nokuqina luya kuqhutywa ngaphambi kokufakwa, kwaye i-valve ingasetyenziselwa kuphela emva kokuba ifanelekile.Ngethuba lovavanyo lwamandla, uxinzelelo lovavanyo luya kuba ngamaxesha angama-1.5 oxinzelelo oluncinci, ubude bexesha abuyi kuba ngaphantsi kwe-5min, kunye negobolondo le-valve kunye nokupakishwa kuya kufaneleka ukuba akukho kuvuza.
Ngokwesakhiwo, i-valve yokulawula ibhola yombane inokwahlulwa ibe yi-offset plate, ipleyiti ethe nkqo, ipleyiti ethambekele kunye nohlobo lwe-lever.Ngokwefomu yokutywina, inokwahlulwa ibe ziindidi ezimbini: uhlobo olutywiniweyo kunye nohlobo olutywiniweyo.Uhlobo lwetywina oluthambileyo luhlala lutywinwe ngeringi yerabha, ngelixa uhlobo lwetywina oluqinileyo luhlala luvalwa ngentsimbi yentsimbi.
Ngokohlobo lokudibanisa, i-valve yokulawula ibhola yombane inokwahlulwa ibe yi-flange uxhumano kunye nokudibanisa i-clamp pair;ngokwemowudi yothumelo, inokwahlulwa ibe yi-manual, i-gear transmission, i-pneumatic, i-hydraulic kunye nombane.
Ukufakwa kunye nokugcinwa kwevalve yokulawula ibhola yombane
1. Ngethuba lofakelo, i-disc kufuneka imise kwindawo evaliweyo.
2. Isikhundla sokuvula kufuneka sinqunywe ngokwe-angle yokujikeleza kwebhola.
3. Kwivalve yebhola enevalve yokudlula, ivalve yokudlula kufuneka ivulwe phambi kokuvula.
4. I-valve yokulawula ibhola yombane iya kufakwa ngokwemiyalelo yokufakela umenzi, kwaye i-valve yebhola enzima iya kunikwa isiseko esiqinileyo.
