Problems solved by technology
[0003] Plug valves on the market are usually used for two-way rotation. After long-term use of two-way rotation, the internal shaft will often be damaged due to repeated rotation, which will cause inconvenience to production and use. For this, we provide a Oil drill adopts plug valve and method of using the same

The invention discloses a plug valve for oil drilling and production and a using method of the plug valve, and relates to the technical field of oil drilling and production. The valve rod is fixedly connected with the valve body, and the valve rod is located on the outer side face of the valve body; the communicating pipeline is fixedly connected with the valve body, the communicating pipeline is located on the outer side face of the valve body, and the communicating pipeline communicates with the interior of the valve body; the throttling mechanism is arranged in the communicating pipeline; the valve is rotationally connected to the interior of the valve body, and a water leakage hole is formed in the valve; the fixing column is fixedly connected with the valve, and the fixing column is located in the valve body; and the one-way rotating mechanism is fixedly connected with the valve body, the one-way rotating mechanism is located in the valve body, and the one-way rotating mechanism is fixedly connected with the valve rod. The valve is driven to rotate through the fixing column, the plug valve is opened for use, only one-way rotation can be achieved for use, permanent damage to the internal shaft block caused by long-time reciprocating rotation is prevented, and convenience is brought.
Description
technical field [0001] The invention relates to the technical field of oil drilling, in particular to a plug valve used in oil drilling and a method for using the same. Background technique [0002] The plug valve is a closing member or a plunger-shaped rotary valve. By rotating 90 degrees, the channel port on the valve plug communicates with or separates from the channel port on the valve body to realize opening or closing. The shape of its valve plug It can be cylindrical or conical. In the cylindrical valve plug, the channel is generally rectangular; in the conical valve plug, the channel is trapezoidal. These shapes make the structure of the plug valve light. The plug valve is a fast switch. The straight-through valve, because the movement between the screw sealing surfaces has a wiping effect, can completely prevent contact with the flowing medium when it is fully open, so it can usually be used for medium with suspended particles. Another important feature of it is It...
