Ama-valve emvemvane eccentric kathathu angasetshenziswa ezimeni zokusebenza ngamazinga okushisa afika ku-600 ° C, futhi izinga lokushisa lomklamo we-valve livame ukuhlotshaniswa nempahla nesakhiwo.

Lapho izinga lokushisa lokusebenza kwevalvu lidlula ama-350 ℃, igiya lezikelemu liyashisa ngokuqhutshwa kokushisa, okuzoshisa kalula i-actuator kagesi, futhi ngesikhathi esifanayo kuzobangela kalula ukuthi opharetha ashise.Ngakho-ke, kumklamo ojwayelekile we-NSEN, isiqu esinwetshiwe esinomklamo wokupholisa we-fin sisetshenziselwa ukuvikela ama-actuator afana nempahla kagesi kanye ne-pneumatics.

Nasi isibonelo esilula.Lapho impahla yomzimba eyinhloko ihlukile futhi izingxenye zangaphakathi ziyizinto ezifanayo, ubude besiqu se-valve esandisiwe ngokuvamile buhlukile ngaphansi kwezinga lokushisa elifanayo lokusebenza.

Lapho uhlobo lokuxhuma luyi-flange, kubalulekile ukunaka ngokukhethekile izinga lokushisa elibucayi lika-538 ℃.Akunconywa ukusebenzisa uxhumano lwe-flange uma izinga lokushisa langempela lokusebenza lidlula i-538 ℃.

Isithombe esilandelayo sibonisa i-carbon steel extension yethu evamile isiqu sokushisa okuphezulu kwe-butterfly valve, izinto ezithile zimi kanje:

Umzimba we-valve-WCB

I-valve disc-WCB

I-Clamp ring-SS304

Seal- SS304+Graphite

Idatha ye-2CR13

Izinga lokushisa eliphezulu elinconyiwe levalvu ngu-425 ℃
