In conjunction with unloading devices or hoppers, sluice valves are typically square or circular, depending on the geometry of the intake and outflow. The advantages of a manual sluice valve include its simple structure, reliable sealing, flexible operation, wear resistance, smooth passage, and simple installation and removal. It is particularly suited for the transportation and regulation of the flow of water, slurry, powder, solid materials, and block/lump materials less than 10mm, and has found widespread application in the pulp & paper, cement, mining, and food industries. It is an excellent device for applications requiring substantial volume control changes, frequent startup/shutdown, and rapid operation.
Sluice gate valve installation tips
- Check the chamber and sealing surface of the valve, and no grit is permitted prior to installation;
- The lens bolt connections must be tightened uniformly;
- The packing component must be pushed to ensure the packing’s flexible sealing and gate-opening capabilities;
- Check the valve model, connection size, and medium flow direction prior to installation to ensure everything is in accordance with the specifications; provide adequate room for the actuator.
- The sluice gate valve is a sort of manually controlled gate that resembles the blade gate valve in appearance. It is also known as the sluice gate valve.
- The sluice valve consists mostly of frames, gates, screws, nuts, and other components utilized in abrasive slurry and liquid systems. By turning the handwheel, the screw moves the screw nut and gate horizontally back and forth to open and close the gate.
- The installation is not restricted by Angle, is simple to operate, and allows the customer to select the actuator according to their needs, such as pneumatic, electric, etc. Different pipe fitting sizes can be achieved by utilizing mounting flanges on each side.
How does Sluice Valve Function?
The sluice valve is controlled by a lift or wedge door to allow for uninterrupted water flow. The higher end of the rod is equipped with a hand-operated wheel or motor that raises and lowers the door, while the lower end is equipped with a circular or wedge-shaped gate to impede the flow of water. Utilizing a threaded rod, the valve must rotate numerous times to move from the open to the closed position, and vice versa, in order to prevent water hammer.
There are two primary types of spindles utilized to raise the sluice valve’s gate.
The spindle or stem is attached to the gate in this sort of valve. When being operated, the spindle valve does not rotate with the handwheel but rather is lifted by the spindle.
In this sort of valve, the spindle is threaded and the gate is threaded internally where it is attached to the spindle. The valve stem does not lift out of position during operation, but rather rotates in place to raise the gate utilizing a thread.
Typically, the sluice valve has the same proportions as the main valve, which has a maximum diameter of 300 mm. For bigger diameters, the size of the valve is roughly two-thirds that of the main valve.
The valve is positioned in a valve chamber with an operating cap or hand wheel. The valve can be opened either clockwise or counterclockwise, as indicated on the shaft’s outer end sluice valve Malaysia.
