¢ Ukuhlolwa kwamandla wei-valve yokunciphisa ingcindezi ngokuvamile ihlanganiswa ngemva kokuhlolwa kocezu olulodwa, futhi ingabuye ihlolwe ngemva kokuhlanganiswa. Ubude besikhathi sokuhlolwa kwamandla: 1 iminithi le-DN 150 mm. Ngemuva kokuthi ama-bellows ahlanganiswe nezingxenye, ukuhlolwa kwamandla kuzokwenziwa ngomoya ngezikhathi ezingu-1.5 zokucindezela okukhulu ngemuva kokusetshenziswa kwe-valve yokunciphisa ingcindezi.
¢Ú Ukuhlolwa kokuvala kuzokwenziwa ngokwendlela yokusebenza yangempela. Uma usebenzisa umoya noma amanzi, ukuhlolwa kuzokwenziwa ngezikhathi ezingu-1.1 zokucindezela okujwayelekile; lapho usebenzisa umusi, ukuhlolwa kuzokwenziwa ngengcindezi ephezulu evumelekile yokusebenza ngaphansi kwezinga lokushisa elisebenzayo. Umehluko phakathi kwengcindezi yokungena kanye nokucindezela kokuphumayo akufanele kube ngaphansi kuka-0.2MPa. Indlela yokuhlola iwukuthi: ngemva kokusetha ingcindezi yokungena, lungisa kancane kancane isikulufu sokulungisa se-valve, ukuze ukucindezela kokuphumayo kungashintsha ngokuzwela nangokuqhubekayo ebangeni eliphezulu nobuncane, ngaphandle kokuma nokugxumela. Ku-valve yokunciphisa umfutho we-steam, lapho ukucindezela kwe-inlet kulungiswa, vala i-valve ye-block ngemuva kwe-valve, futhi ukucindezela kokuphuma kuyinani eliphakeme kakhulu neliphansi kakhulu. Phakathi nemizuzu emi-2, ukwazisa kokucindezela kwe-outlet kufanele kuhlangabezane nezinhlinzeko kuthebula 4.176-22, futhi umthamo wepayipi ngemuva kwe-valve kufanele uhlangabezane nezinhlinzeko kuthebula 4.18. Ku-valve yokunciphisa umfutho wamanzi nomoya, lapho ukucindezela kwe-inlet kulungiswa futhi ingcindezi yokuphuma ingu-zero, vala i-valve yokunciphisa ingcindezi yokuvala Ukuhlolwa kuyafaneleka uma kungekho ukuvuza kungakapheli imizuzu emi-2.
