¢ Uvavanyo lwamandla eivalve yokunciphisa uxinzelelo idityaniswa ngokubanzi emva kovavanyo lweqhekeza elinye, kwaye inokuvavanywa kwakhona emva kokuhlangana. Ubude bexesha lovavanyo lwamandla: 1 min ye-DN 150 mm. Emva kokuba i-bellows idibene kunye namacandelo, uvavanyo lwamandla luya kuqhutywa ngomoya ngamaxesha angama-1.5 oxinzelelo oluphezulu emva kokusetyenziswa kwe-valve yokunciphisa uxinzelelo.
¢Ú Uvavanyo lokutywina luya kwenziwa ngokweyona ndlela yokusebenza. Xa usebenzisa umoya okanye amanzi, uvavanyo luya kwenziwa ngamaxesha e-1.1 yoxinzelelo oluncinci; xa usebenzisa i-steam, uvavanyo luya kuqhutywa kuxinzelelo oluphezulu oluvumelekileyo lokusebenza phantsi kobushushu bokusebenza. Umahluko phakathi koxinzelelo lokungena kunye noxinzelelo lokuphuma aluyi kuba ngaphantsi kwe-0.2MPa. Indlela yokuvavanya: emva kokuba uxinzelelo lwe-inlet lusetyenzisiwe, ngokuthe ngcembe ulungelelanise i-screw yokulungelelanisa i-valve, ukwenzela ukuba uxinzelelo lwe-outlet lutshintshe ngokukhawuleza kwaye ngokuqhubekayo kuluhlu oluphezulu kunye nobuncinci, ngaphandle kokumisa kunye ne-jamming. Kwi-valve yokunciphisa uxinzelelo lwe-steam, xa uxinzelelo lwe-inlet luhlengahlengiswa, vala i-valve yebhloko emva kwevalve, kwaye uxinzelelo lwe-outlet luphezulu kwaye ixabiso eliphantsi. Ngaphakathi kwemizuzu emi-2, ukuxatyiswa koxinzelelo lokuphuma kufuneka kuhlangabezane nemimiselo kwitheyibhile 4.176-22, kunye nomthamo wombhobho emva kwevalve kufuneka uhlangabezane nemimiselo kwitheyibhile 4.18. Kumanzi kunye ne-valve yokunciphisa uxinzelelo lomoya, xa uxinzelelo lwe-inlet luhlengahlengiswa kwaye uxinzelelo lwe-outlet luyi-zero, vala i-valve yokunciphisa uxinzelelo lokutywinwa Uvavanyo lufanelekile ukuba akukho kuvuza ngaphakathi kwemizuzu emi-2.
