What is dome valve?

Dome valve is one of the most effective and fast opening and closing material conveying valve in the world, and it is also a key valve in the international coal-fired power plant ash conveying system with a large number of use and with premium effect, In the operation of the system, it is used to cut off and connect the blanking between the ESP ash hopper and the bin pump, used as the discharge valve of the bin pump, the delivery discharge valve of the unit bin pump, and the switching dome valve of the ash silo, as the discharge dome valve of the ash silo, etc.

The unique feature of the dome valve is that it can cut off the flowing material flow into the pressure tank or the static material column, and then close to achieve sealing. Thus, the filling rate of the pressure tank is 100%, and it does not depend on the level gauge of the sending tank, so the control principle is simple and reliable.

Only one maintenance is needed for 1000000 times of rated operation, which greatly reduces the maintenance cost and the loss of equipment outage. The pneumatic conveying system adopts dome valve to ensure the reliability and efficiency of system operation.
