There are several reasons why a high-pressure ball valve is not closed properly:
Transmission mechanism failure:The transmission mechanism of the high-pressure ball valve includes a manual operation device, an electric device or a pneumatic device, if the transmission mechanism fails, such as breakage, loosening, stuckness, etc., it will lead to the ball valve not being closed properly.
Leakage Issues:The inadequate closure of the high-pressure ball valve may be due to leakage problems inside the ball valve, such as worn seals, loose seals, etc., which cause the ball valve to not close completely.
Ball valve structure problem:Unreasonable structural design or manufacturing defects of ball valves may also lead to inadequate closing, such as poor fit between the ball and the sealing surface, wear of the sealing surface, etc.
Interference from external forces:External factors such as pipe vibration, shock, transition flow rate, etc., can also cause the ball valve to close inadequately.
Operation error:Incorrect use of the ball valve by the operator, such as insufficient closing force, incorrect operation, etc., may also result in inadequate closing.
To solve the problem that the high-pressure ball valve is not closed in place, the following measures can be taken:
Check the transmission mechanism:Check whether the transmission mechanism is operating normally, repair or replace the faulty parts.
Check the seals:Check whether the sealing ring inside the ball valve is in good condition, and replace it in time if it is worn or loose.
Check the ball valve structure:Check whether the structure of the ball valve is reasonable, and if there are defects, you can consider replacing the ball valve or repairing it.
Reduce external interference:Take measures to reduce the impact of external forces such as vibration and impact on the ball valve.
Specification Operation:Provide operator training to ensure proper operation of the ball valve, including the correct force and procedure.
The above is a summary of the reasons and solutions for the failure of the high-pressure ball valve to close in place, I hope it can help you.
