Background
In the field development process, workover operations are often required for a variety of reasons. For some water wells with low pressure and large overflow, in the pipe lifting process, well liquid overflowing from the pipe can be blown out far in wind along with the lifting of the large hook, so that the well site is polluted, and farmland or mountain forests around the well site are polluted. For such wells, temporary plugging of tubing joints is required. At present, a suspension plug valve is generally adopted in the industry to plug a tubing coupling, and the suspension plug valve is a valve which is opened or closed by rotating a valve core by 90 degrees to enable a passage port on the valve core to be communicated with or separated from a passage port on a valve body. The shape of its valve core can be cylindrical or spherical. The suspension plug valve is suitable for cutting off, connecting media and shunting, and if the suspension plug valve needs to be assembled and disassembled once in each oil pipe in the well repairing process, time and labor are wasted, and the suspension plug valve is not economical.
