Design feature:

• Valve body: the main pressure-bearing structure of the valve, including all internal parts in contact with the controlled fluid.

• Valve cover: provide leak-proof sealing to protect the internal parts of the valve.

• Disc: a plug-shaped opening and closing piece that moves linearly along the center line of the fluid.

• Seat: cooperate with disc to realize sealing.

• Valve stem: connects the disc with an external handwheel or actuator, and is used to control the up-and-down movement of the disc.

Maintenance:

1. Check the sealing performance of the valve regularly, and replace the gasket in time if water leakage is found.

2. When the valve is not used for a long time, the valve should be closed and the internal residue should be cleaned to ensure the normal use of the valve.

3. The handle and stem of the valve should be kept clean and lubricated to ensure smooth operation.
