OneThere may be several reasons why the gate valve does not die:
Gate valve seal surface damage:If the sealing surface of the gate valve is damaged or there are impurities, the seal will not be tight, so that the gate valve cannot be completely closed.
Loose gate stem or nut:If the gate stem or nut is loose, the ram will not close completely.
Gate valve internal structure failure:The internal parts of the gate valve, such as sealing rings and springs, will also affect the closing of the gate valve if they are damaged or loose.
IIThe steps are as follows:
Check the sealing surface of the gate valve:Close the pipeline related to the gate valve first, use a manual rod or tool to close the gate plate in place, check whether there is damage or impurities on the sealing surface of the gate valve, if there is damage, the sealing surface needs to be replaced, and if there are impurities, it can be cleaned.
Check the gate stem and nut:Check the gate stem and nut with your hand or tool for looseness, if so, you need to lock the loose part.
Check the internal structure of the gate valve:Disassemble the gate valve, inspect the internal structure for damaged or loose parts, and replace them if there is damage.
Cleaning and lubrication:Clean the gate valve, remove impurities and dirt, and apply the appropriate amount of lubricant.
The above are the general steps to deal with the gate valve not to die, and it is recommended to refer to the instruction manual of the gate valve or consult the relevant professionals of Detersen for specific operation. Please note that you need to pay attention to safety during operation to avoid electric shock and other hazards.
