Some common faults may occur during the use of the flat gate valve, such as leakage of the sealing surface, jamming of the valve rod, and falling off of the gate plate. In order to ensure the normal operation and extend the service life of the flat gate valve, it is necessary to take corresponding measures to handle these faults in time.
Leakage of sealing surface: leakage of sealing surface is one of the common faults of flat gate valve. The methods to deal with the leakage of the sealing surface include replacing the sealing ring, adjusting the compression amount of the sealing ring, and cleaning the sealing surface. If the sealing surface leaks seriously, the valve may need to be removed for thorough inspection and repair.
Valve stem jamming: valve stem jamming is one of the common faults of flat gate valve. The methods for handling jamming of the valve stem include cleaning the valve stem, adjusting the fit between the valve stem and the stuffing box, replacing the packing, etc. If the valve stem is seriously jammed, it may be necessary to disassemble the valve for comprehensive inspection and repair.
Falling off of gate plate: falling off of gate plate is one of the serious faults of flat gate valve, which shall be handled immediately. The methods to deal with the falling off of the ram include replacing the ram, adjusting the assembly position of the ram, reinforcing bolts, etc. If the gate falls off seriously, the entire valve may need to be replaced.

Blockage of fluid channel: Blockage of fluid channel will affect the normal operation of flat gate valve. The treatment methods for fluid channel blockage include cleaning the fluid channel, cleaning impurities in the fluid, etc. If the fluid path is severely blocked, the valve may need to be removed for thorough inspection and repair.
Transmission device failure: the transmission device failure of the flat gate valve will affect its normal operation. The methods to deal with the failure of the transmission device include checking the components of the transmission device, replacing the damaged components, adjusting the fit of the transmission device, etc. If the actuator fails seriously, the entire actuator or valve may need to be replaced.
To sum up, correct treatment of common faults of flat gate valve requires corresponding measures for different faults. It is recommended to follow the following steps when dealing with the fault: first check and determine the type and cause of the fault; Then take corresponding measures according to the fault type and cause; Finally, test and verify to ensure that the flat gate valve returns to normal working condition. At the same time, it is suggested to regularly maintain the flat gate valve to prevent common faults.
