Remove the original one-way valve of the oil pump.
Connect the multi-functional fixed valve to the oil pump and lower it down
The multifunctional fixed valve and oil well pump are connected to the well string, and a wellhead pressure setting and sealing packer is installed.
After the packer seat is sealed, the limit seat inside the fixed valve is pushed down and collided with the steel ball by the pump rod of the oil well, which can be used as a one-way valve for oil extraction operations.
When the oil needs to be drained during the lifting of the string, the ball valve is pressed down by the suspended weight of the pumping rod, and the ball valve will open to drain the oil.
