In the process flow of mining machinery, the combined slurry valve drives the rise and fall of the valve rod and gate through the hydraulic cylinder to prevent the opening and closing of the valve. When the valve is opened, the hydraulic cylinder provides power to pull the valve rod and drive the ram to move downward. When the ram drops to a specific height, the hole on the ram is aligned with the hole on the sealing plate and equal to the inner diameter of the outer pipeline. At this time, the valve forms a short channel, thus forming a smooth channel. When the valve is closed, the ram rises and the ram locks the channel. The length from the fully open position to the gate position when the gate is dead is the stroke of the valve. Combined slurry valve is a new type of valve, which is widely used in the slurry transportation of granular materials in mining, power plant, metallurgy, chemical industry and other departments. Let's talk about the working principle of combined pulp valve. Working principle and characteristics of combined pulp valve.
