| Shaanxi Rongle Petroleum Machinery Co.,Ltd is one of the best China below packer hydraulic safety joint manufacturers and suppliers,Website:http://www.snrle.com, and also a professional co***ny and factory, welcome to import quality below packer hydraulic safety joint products from us.Application It is used for fracturing by layer,acidification by layer,testing string and other construction.E type differential circulating valve is a full bore test valve according to the special needs in the process of down-hole operation and is suitable for high pressure oil wells in the cycle operation. The circular hole is always in open position in the process of cycle operation. After completing the cycle operation, you can close the circular hole by operation. Once a loop hole is closed, you will not be able to turn it on again. Working principles and structural characteristics E type differential circulating valve is made up of ball valve part and cycling part. During the cycle operation, the circular hole is always open under the action of shearing pins. After completing the cycle operation, putting a steel ball into the oil pipe from the wellhead, the steel ball automatically sits in a ball seat under the action of gravity and blocks tubing diameter. Then, using a pump truck to inject liquid to the oil pipe in a continuous speed. The flow rate is not less than 2m ³/min. Because the ball seat position cannot be absolutely sealed, when the liquid passes through the ball seat, it then forms resistance flow in the pipe column of the top of ball seat. Larger the flow, more obvious the resistance flow effect. When the resistance flow pressure on the upper ball seat reaches shearing stress of shear pin, shear pin will be cut to close the circular hole. In the course of this tool in the operation, once a circular hole is closed, you will not be able to turn it on again. |
