Tool Introduction

The pump flushing reverse circulation valve is a backup circulation valve. When the broken pin of the broken pin reverse circulation valve cannot be broken, pressure is applied from the pipe column to 8-10 MPa, the shear pin of the pump flushing reverse circulation valve is cut off, the pump striking plate is opened, and the stroke circulation channel is opened.

Structural characteristics

① The tool structure is simple, easy to operate and reliable;

② Open the circulation channel by pressurizing inside the oil pipe.

operation

After the test is completed, pressurize the pipe column with 8-10 MPa, cut off the shear pin of the pump flushing circulation valve, open the pump striking plate, and open the stroke circulation channel.
