Recently, the SK-1 type pumping well ground check valve was successfully developed in Shengli Oilfield Shengli No. 4 Mine.
The device was developed by the technical research team of Shengli Oilfield Shengli Mining Technology Management Station for more than three months. The check valve is installed inside the nozzle sleeve. The ball is used in the hemisphere and the back is connected with the righting rod to avoid the spring. The lateral displacement of the sphere caused by the reduction of the elastic force produces the non-homing of the sphere. At the same time, as the volume of the valve cavity increases, the flow passage area increases, the flow resistance is lowered, the efficiency of the pumping system is improved, and the pump diameter of various specifications can be satisfied. Different needs.
The device is small in size and light in weight, and is connected by a threaded button. When replacing, one person can complete it in 10 minutes, thereby avoiding the series of problems such as replacement of the necessary electric welding, reducing the workload, improving the safety and reliability, and reducing the safety. Loss of production. At present, the ground check valve has been field-installed and tested in several wells of the mine, and achieved remarkable results.
