Mining Water Distribution Gate is a specially designed device for distributing water in various water intake wells of mine pump houses, featuring its lightweight, simple structure, easy operation, and good sealing performance. Below is a detailed introduction to the mining water distribution gate:
Types and Features
Mining water gate valves mainly come in two types:
PZ1 Type Water Distribution Gate Valve: This is the basic model, suitable for manual operation, with a simple structure and easy operation.
PZ2 Type Explosion-Proof Water Distributing Valve: Improved design based on the PZ1 type, featuring an electric device for automation needs, offering more convenient operation.
Structure and Working Principle
Mining water gate operates by the valve rod to vertically lift or lower the gate plate for opening and closing. As the valve rod rotates clockwise, the gate plate is pressed down and tightly seals with the valve seat, cutting off the water flow; rotating counterclockwise, the gate plate rises, the passage opens, and the water flow resumes. This structure effectively reduces water hammer effect, ensuring smooth system operation.
Application Scenario
Mine drainage gate is mainly used for water distribution in various intake wells of the underground pump house in mines, and can also be used for water discharge in ore dressing and water treatment ponds. It is suitable for water without corrosive medium, with water temperature not exceeding 80°C.
Technical specifications and installation precautions
Nominal Diameter: Ranges from 400mm to 1200mm.
Medium Temperature: Not exceeding 80℃.
Nominal Pressure: 0.1 MPa (Test Pressure: 0.25 MPa).
Operation Stroke: Varies by model, ranging from 220mm to 350mm._
Please note the following points during installation:
The valve body arrow must align with the medium flow direction to prevent reverse installation causing seal failure.
Large bore valves require additional reinforced supports to prevent pipeline vibration from affecting the sealing performance.
Ensure even tightening of bolts diagonally when connecting flanges to ensure even distribution of force.
Provide clearance for valve rod operation, facilitating manual adjustment or replacement of packing later.
