Eqinisweni, i-valve yokulawula kagesi isetshenziswe kabanzi embonini nasezimayini. I-valve yebhola yokulawula kagesi ivame ukwakhiwa yi-actuator kagesi ye-angular stroke kanye ne-valve ye-butterfly ngokuxhumeka komshini, ngemuva kokufakwa nokulungisa amaphutha. I-valve yebhola yokulawula kagesi ngokwesigaba semodi yesenzo: uhlobo lokushintsha kanye nohlobo lomthethonqubo. Okulandelayo incazelo eyengeziwe ye-valve yebhola yokulawula kagesi.
Kunamaphuzu amabili ayinhloko ekufakweni kwe-electric control ball valve
1) Indawo yokufaka, ukuphakama kanye nesiqondiso sokungena kanye nesokukhipha kumele kuhlangabezane nezidingo zomklamo. Isiqondiso sokugeleza okuphakathi kufanele sihambisane nesiqondiso somcibisholo ophawulwe emzimbeni wevalvu, futhi uxhumano kufanele luqine futhi luqine.
2) Ngaphambi kokufakwa kwevalvu yokulawula kagesi, ukuhlolwa kokubukeka kumele kwenziwe, futhi ipuleti legama levalvu kumele lihambisane nezinga lamanje likazwelonke elithi "uphawu lwevalvu olusebenzisa ngesandla" GB 12220. Kuvalvu enengcindezi yokusebenza engaphezu kwe-1.0 MPa kanye nomsebenzi wokunqunywa epayipini eliyinhloko, ukuhlolwa kwamandla nokuqina kufanele kwenziwe ngaphambi kokufakwa, futhi ivalvu ingasetshenziswa kuphela ngemva kokuba ifanelekile. Ngesikhathi sokuhlolwa kwamandla, ingcindezi yokuhlola kufanele ibe izikhathi eziyi-1.5 zengcindezi evamile, ubude akufanele bube ngaphansi kwemizuzu emi-5, futhi igobolondo levalvu kanye nokupakisha kufanele kuqinisekiswe uma kungekho ukuvuza.
Ngokwesakhiwo, i-valve yebhola yokulawula kagesi ingahlukaniswa ibe yi-offset plate, i-vertical plate, i-inclined plate kanye nohlobo lwe-lever. Ngokwesimo sokuvala, ingahlukaniswa ibe izinhlobo ezimbili: uhlobo oluvalwe ngokulinganayo kanye nohlobo oluvalwe ngokuqinile. Uhlobo lokuvala oluthambile luvame ukuvalwa ngendandatho yerabha, kanti uhlobo lokuvala oluqinile luvame ukuvalwa ngendandatho yensimbi.
Ngokusho kohlobo lokuxhuma, i-valve yebhola yokulawula kagesi ingahlukaniswa ngokuxhumeka kwe-flange kanye nokuxhumeka kwe-clamp ye-pair; ngokusho kwemodi yokudlulisela, ingahlukaniswa ngokudluliselwa ngesandla, kwegiya, komoya, komoya kanye nogesi.
Ukufakwa nokugcinwa kwevalvu yebhola yokulawula kagesi
1. Ngesikhathi sokufakwa, idiski kufanele ime endaweni evaliwe.
2. Indawo yokuvula kufanele inqunywe ngokwe-engeli yokujikeleza kwebhola.
3. Kwi-ball valve ene-bypass valve, i-bypass valve kufanele ivulwe ngaphambi kokuvula.
4. Ivalvu yebhola yokulawula kagesi kufanele ifakwe ngokwemiyalelo yokufaka yomenzi, futhi ivalvu yebhola esindayo kufanele inikezwe isisekelo esiqinile.
Isikhathi sokuthunyelwe: Feb-16-2023
