How to install mining water distribution gate valve correctly?

1、 Preparation before installation

1. ‌reserved holeWhen pouring into the wellbore, it is necessary to reserve short pipe holes and channel steel holes to support the gate valve in advance. Foundation holes should be reserved on the pump room floor1.

2. ‌Component inspectionConfirm that components such as gate valves, control consoles, connecting rods, and valve stems are intact and free from deformation or corrosion2.

2、 Installation steps

1. ‌Connect the short pipe to the gate valveAlign and fix the gate valve flange with the short pipe flange, insert it into the reserved hole, and adjust the verticality by exposing the valve stem1.

2. ‌Console in placeRaise the screw according to the size requirements in the manual to ensure the stability of the console base2.

3. ‌Installation of connecting rodMeasure the height difference between the bottom plate of the water distribution well and the bottom plate of the pump room, determine the length of the connecting rod, install it, and fix the connection between the valve stem and the screw rod2.

3、 Debugging and sealing

1. ‌Operational testingRotate the handwheel to drive the screw up and down, and check whether the gate valve opens and closes smoothly without any jamming phenomenon2.

2. ‌Sealing treatmentAdd a sealing gasket at the joint between the valve cover and the valve body, fill the space between the valve stem and the sealing block with a packing and press it tightly with a packing cover to prevent leakage.

4、 Precautions

• ‌Verticality calibrationThe verticality deviation of the valve stem should be controlled within the allowable range to avoid sealing failure caused by uneven force on the gate plate1.

• ‌regular maintenanceAfter installation, it is necessary to regularly clean impurities, check the wear of the sealing surface, and replace damaged gaskets or valve stems in a timely manner3.
