In view of the problems in pumping wells in the No. 4 Oil Production Plant of PetroChina Huabei Oilfield Company, such as frequent failures of check valves in daily production, long shut-down time during maintenance, impact on crude oil production and high safety risk during maintenance, a new type of double-control check valve has been invented. This check valve has the dual functions of ordinary lift check valve and stop valve, which avoids the unsafety in the operation process, improves the well opening time rate of pumping wells, and has the advantages of simple operation, long service life, simple structure, convenient repairing and recycling, and considerable procurement cost is saved.
