Amavalvu ebhabhathane angavamile amathathu angasetshenziswa ezimweni zokusebenza ezinamazinga okushisa afinyelela ku-600°C, futhi izinga lokushisa lomklamo wevalvu livame ukuhlotshaniswa nezinto kanye nesakhiwo.
Uma izinga lokushisa lokusebenza kwevalvu lidlula u-350℃, igiya le-worm liyashisa ngokushisa, okuzoshisa kalula i-actuator kagesi, futhi ngesikhathi esifanayo kubangele kalula ukuthi umqhubi ashise. Ngakho-ke, ekwakhiweni okujwayelekile kwe-NSEN, isiqu sesandiso esinomklamo wephini lokupholisa sisetshenziswa ukuvikela ama-actuator njengemishini kagesi kanye ne-pneumatics.
Nasi isibonelo esilula. Uma izinto zomzimba eziyinhloko zihlukile futhi izingxenye zangaphakathi ziyizinto ezifanayo, ubude besiqu se-valve esandisiwe buvame ukuhluka ngaphansi kwezinga lokushisa elifanayo lokusebenza.
| 主体材质 Izinto zomzimba | 使用温度 Izinga lokushisa elisebenzayo | 阀杆加长 Ukunwetshwa kwesiqu |
| I-WCB | 350℃ | 200mm |
| I-WC6/WC9 | 350℃ | 300mm |
Uma uhlobo lokuxhuma luyi-flange, kubalulekile ukunaka kakhulu izinga lokushisa elibucayi elingu-538℃. Akukhuthazwa ukusebenzisa uxhumano lwe-flange uma izinga lokushisa lokusebenza langempela lidlula u-538℃.
Isithombe esilandelayo sibonisa i-valve yethu evamile ye-carbon steel extension stem high temperature butterfly, izinto ezithile yilezi ezilandelayo:
Umzimba we-valve-WCB
Idiski ye-valve-WCB
Indandatho ye-clamp-SS304
I-Seal- SS304+Graphite
Isiqu- 2CR13
Izinga lokushisa eliphezulu elinconywayo levalvu lingu-425℃
