Abstract

The invention provides a reversing device for fracturing operation. The reversing device comprises a body, a cock, a valve rod, a piston and a first handle. The cock is assembled in a cavity of the body, a fracturing mixed liquid inlet is formed in the top end of the cock, and a first fracturing mixed liquid outlet communicating with the fracturing mixed liquid inlet is formed in the side portionof the cock. At least two sets of second fracturing mixed liquid outlets capable of rotationally communicating with the first fracturing mixed liquid outlet are formed in the side portion of the body.The piston is connected to the bottom end of the body in a sealed manner, and the interior of the piston is in threaded connection with the valve rod. The end, stretching into the body, of the valverod is in threaded connection with the bottom end of the cock, and the first handle is fixed to the end, stretching out of the body, of the valve rod. According to the reversing device, a traditionalfive-way valve and a gate valve are fused into a whole, fluid leakage points are reduced, the overall structure is optimized, cost is greatly reduced, sealing is facilitated, operation is simple, andthe installing and maintaining time is saved.

Description

technical field [0001] The invention relates to a reversing device, in particular to a reversing device used in fracturing operations. Background technique [0002] Multi-wellhead operations often occur on oilfield sites. During fracturing operations, the fracturing fluid is discharged through high and low pressure manifolds, and flows to each wellhead through a diversion device. The traditional diversion device usually consists of a five-way 100 and a flat gate valve 200 (such as figure 1 and 2 As shown), when a wellhead is performing fracturing operations, the fracturing fluid enters the five-way cavity through the top of the five-way, opens the gate valve connected to the wellhead, and closes the other outlet gate valves to ensure that there is no leakage at the other outlets. Fracturing operations at the wellhead. Based on the large structure and cumbersome operation process of the traditional diversion device, a reversing device used in fracturing operations is now d...
