Background technique

The existing material guide devices are mainly plate type three-way valves, four-way valves, etc., which are used to transfer materials from one process flow to another. However, when problems such as poor sealing and deformation of the material guide plate often occur, It is necessary to add a flat gate valve at the corresponding discharge end.

The first is that the sealing is not strict when it is used for the distribution and guiding of fine powder materials. The main reasons for the poor sealing are: 1. There is a gap between the material guide plate and the edge, which is washed by the fine powder material, resulting in an increase in the gap. 2. Due to the impact of the reciprocating motion of the actuator, the material guide plate is deformed, resulting in poor sealing and the occurrence of material leakage; 3. The improper positioning of the actuator causes the leak to occur Channeling phenomenon.

The second is that a flat gate valve needs to be added to ensure the sealing effect after material channeling occurs.
