Ukwethulwa kafushane kwezinto ezibalulekile zokufakwa nokugcinwa kwe-valve yokulawula ibhola kagesi

Eqinisweni, i-valve yokulawula kagesi isetshenziswe kabanzi embonini nasezimayini. I-valve yebhola yokulawula kagesi ivamise ukwakhiwa nge-angular stroke actuator kanye ne-butterfly valve ngoxhumano lwemishini, ngemva kokufakwa nokulungisa iphutha. I-valve yebhola yokulawula kagesi ngokuya ngesigaba semodi yesenzo: uhlobo lokushintsha nohlobo lokulawula. Okulandelayo incazelo eyengeziwe ye-valve yebhola yokulawula kagesi.

Kunamaphuzu amabili ayinhloko ekufakweni kwe-valve yebhola yokulawula kagesi

I-1) Indawo yokufaka, ubude kanye nesiqondiso se-inlet ne-outlet kumele ihlangabezane nezidingo zokuklama. Isiqondiso sokugeleza okuphakathi kufanele sihambisane nesiqondiso somcibisholo omakwe emzimbeni wevalvu, futhi ukuxhuma kuzoqina futhi kuqine.

2) Ngaphambi kokufakwa kwe-valve yebhola yokulawula kagesi, ukuhlolwa kokubukeka kufanele kwenziwe, futhi ipuleti yegama le-valve kufanele ihambisane nezinga likazwelonke lamanje "uphawu lwe-valve manual" GB 12220. Ukuze i-valve enengcindezi yokusebenza enkulu kuno-1.0 MPa nomsebenzi wokusika epayipini elikhulu, ukuhlolwa kwamandla nokuqina kuzokwenziwa ngaphambi kokufakwa, futhi i-valve ingasetshenziswa kuphela ngemva kokufakwa. Ngesikhathi sokuhlolwa kwamandla, ingcindezi yokuhlola izoba izikhathi ezingu-1.5 zokucindezela okulinganiselwe, ubude besikhathi ngeke bube ngaphansi kwe-5min, futhi igobolondo le-valve nokupakisha kuzofaneleka uma kungekho ukuvuza.

Ngokusho kwesakhiwo, i-valve yebhola yokulawula kagesi ingahlukaniswa ibe yi-offset plate, ipuleti eqondile, ipuleti ethambekele kanye nohlobo lwe-lever. Ngokwefomu lokufaka uphawu, lingahlukaniswa ngezinhlobo ezimbili: uhlobo oluvalwe ngokuqhathaniswa nohlobo oluvalwe kanzima. Uhlobo lophawu oluthambile luvamise ukuvalwa ngendandatho yerabha, kanti uhlobo lophawu oluqinile luvamise ukuvalwa ngendandatho yensimbi.

Ngokusho kohlobo lokuxhuma, i-valve yebhola yokulawula kagesi ingahlukaniswa ibe uxhumano lwe-flange kanye nokuxhumeka kwe-clamp pair; ngokuya ngemodi yokudlulisa, ingahlukaniswa ngemanuwali, ukuhanjiswa kwegiya, i-pneumatic, ihydraulic kanye nogesi.

Ukufakwa nokugcinwa kwe-valve yebhola yokulawula kagesi

1. Ngesikhathi sokufakwa, i-disc kufanele ime endaweni evaliwe.

2. Isikhundla sokuvula kufanele sinqunywe ngokuvumelana ne-angle yokujikeleza yebhola.

3. Nge-valve yebhola ene-bypass valve, i-valve yokudlula kufanele ivulwe ngaphambi kokuvula.

4. I-valve yebhola yokulawula kagesi izofakwa ngokulandela imiyalelo yokufaka yomkhiqizi, futhi i-valve yebhola esindayo izohlinzekwa ngesisekelo esiqinile.
