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 uqhagamshelo luya kuba luqilima kwaye luqine.
2) Ngaphambi kokufaka i-valve yokulawula i-valve yombane, ukuhlolwa kwembonakalo kufuneka kuqhutywe, kwaye ipleyiti yegama levalve iya kuhambelana nomgangatho wangoku wesizwe "uphawu lwevalve ye-manual" GB 12220. Kuba ivalve enoxinzelelo olusebenzayo olungaphezu kwe-1.0 MPa kunye nomsebenzi wokunqunyulwa kumbhobho oyintloko, uvavanyo lwamandla kunye nokuqina luya kuqhutywa ngaphambi kokufakwa, kwaye ivalve ingasetyenziswa kuphela emva kokufakwa. 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.
