Flow guiding pneumatic knife-shaped sluice valve

Abstract

一种导流型气动刀形闸阀,包括气动刀形闸阀本体、连接在阀门腔体周围的气体吹扫管路和导流体。导流体为内锥形短管,其大径端设有翻边,导流体通过该翻边连接在阀门进口端的法兰上,导流体的小径端伸入阀门腔体内接近闸板。本实用新型导流型气动刀形闸阀可以更好地避免固体颗粒的沉积,大大减少维修成本。并且应用广泛,安装方便。
The utility model discloses a flow guiding pneumatic knife-shaped sluice valve, which comprises a pneumatic knife-shaped sluice valve body as well as an air blowing and sweeping pipeline and a flow guiding body connected with the surrounding of the cavity of the valve. The flow guiding body is an internal conical short pipe and the larger diameter end thereof is provided with flanging; the flow guiding body is connected with a flange at the inlet end of the valve through the flanging; the smaller end of the flow guiding body stretches into the cavity of the valve to approach to a sluice board. The flow guiding pneumatic knife-shaped sluice valve can better avoid the deposition of solid particles, and can greatly reduce the maintenance cost; moreover, the flow guiding pneumatic knife-shaped sluice valve is applied widely, and is convenient to be mounted.
