産品特點
刀型閘閥通過配用電磁閥、接近開關等附件可以完成開、關兩位置的動作控制和信号輸出,也可以完成連續動作的自動控制。刀型閘閥廣泛用于化工、煤碳、制糖、污水、造紙等領域,是一種理想的密封閥門。刀型閘閥特别适合于造紙行業在管道上作調節和節流使用。 

刀型閘閥主要由左、右閥體、U型密封圈、閘闆、鋼螺母、閥杆、支架、氣缸等件組成,閥門啟閉靠氣缸動作來完成。 

刀型閘閥結構特點主要有:
1、采用對夾式結構,體積小,重量輕。
2、完全敞開的通道,可以防止介質在閥内沉積。
3、新研制的U型封圈,可以保證閥門的良好密封性。
4、閘闆的外密封,則是通過嵌在閥體内具有彈性的密封條來實現,并可借助于螺釘,壓闆進行調整。
5、流阻小。
6、安裝維修方便。
