Outlet device mainly apply raw material homogenization silo and cement silo as equipment of bottom silo and side silo. It has the function of cutting off material flow, on-off control and outlet flow together. The whole system is composed of screw gate, pneumatic on-off valve and motorized(pneumatic) flow control valve. The user can select them according to his need. It may use one equipment alone, to cut off powder material or outlet control device.
Structural Features
The pneumatic/electric shut-off valve and electric/pneumatic flow control valve of the discharge device feature a flexible sealing structure.
The flexible sealing design employs a felt packing that is fitted and pressed between the valve core and the valve body. This structure is compact and simple, offering excellent sealing performance. The sealing elements can be replaced conveniently without disassembling the valve body.
The opening and closing of the pneumatic shut-off valve are driven by a cylinder, while the electric shut-off valve is actuated by an electric linear actuator.
The flow control of the electric/pneumatic flow control valve is achieved by adjusting the opening angle of the valve core. The electric flow control valve is regulated by an electric actuator, whereas the pneumatic flow control valve is regulated by a pneumatic actuator. The pneumatic actuator features rapid response speed and is equipped with a fail-safe close function (air-to-close) upon power failure.

Maintenance & Servicing
1. Screw Gate: The lead screw of the screw gate is equipped with two oil cups, which should be regularly lubricated. If the sealing components between the valve body and the gate plate show signs of wear, they should be replaced. If agglomerates or foreign matter become lodged between the gate plate and the sealing components, they should be cleaned out. The gate plate passage through the valve body is sealed with gland packing. In case of leakage, the bolts on the gland packing plate should be tightened. If the packing becomes worn, it should be replaced.
2. Shut-Off Valve & Flow Control Valve: The bearings at both ends of the shut-off valve and flow control valve are equipped with grease nipples and should be lubricated regularly, with a thorough cleaning once a year. The inner surface of the valve body should be inspected frequently for damage caused by foreign objects, and all debris should be removed to prevent material buildup and valve damage. After prolonged operation, the clearance between the valve core and the sealing elements may increase due to wear, and should be adjusted or replaced in a timely manner.
3. For replacement of wear parts, please contact our factory.
4. Auxiliary equipment such as cylinders, electric linear actuators, electric actuators, and pneumatic actuators shall be maintained and serviced in accordance with their respective instruction manuals.
