Description
1. BASIC INFORMATION ABOUT THE ARTICLE Check ball valve SHOK-73-175 (hereinafter referred to as valve) is intended for use in oil production by submersible pumps. It automatically prevents the backflow of liquid and keeps the liquid in the tubing string (tubing) and the oil pipeline after the pump stops. The valve is a steel cylindrical body, on the ends of which there is a thread for its installation in the tubing string. Inside the housing there is a ball-seat valve pair V11-175 according to API standard. During operation of the pump, liquid enters the valve housing and, lifting the ball above the seat, passes through holes in the housing into the tubing string. When the pump stops under the action of its own weight and pressure of the liquid column, the ball is tightly pressed to the seat and provides reliable sealing, keeping the liquid column in the tubing string for the entire time from the moment the pump stops. 2. BASIC TECHNICAL DATA The valve is manufactured in three versions. The valve design depends on the material of the ball-seat valve pair.
