Problems solved by technology
[0003] Usually, when the user does not use the butterfly valve, it is generally closed by turning the valve stem. When not in use, when the staff uses other equipment, they may accidentally touch the valve stem and cause the butterfly valve to start, causing trouble. In this regard, we propose a butterfly valve used in oil drilling and its use method

The invention discloses a butterfly valve for oil drilling and production and a using method of the butterfly valve, and relates to the technical field of oil drilling and production. The butterfly plate is rotationally connected with the valve body, and the butterfly plate is located on the inner wall of the valve body; the fixed column is rotationally connected with the valve body, and the fixed column is fixedly connected with the butterfly plate; the fixing block is fixedly connected with the fixing column, and the fixing block is located on the upper surface of the fixing column; the valve rod structure is fixedly connected with the fixing block, and the valve rod structure is located on the outer wall of the fixing block; the dismounting rod structure is fixedly connected with the valve rod structure, and the dismounting rod structure is located at one end of the valve rod structure; and the fixing structure is fixedly connected to the interior of the fixing block. According to the butterfly valve, the valve rod can be conveniently taken down and placed aside, the situation that the butterfly valve is loosened due to accidental touch is prevented, the use safety of the butterfly valve is guaranteed, and a better prospect is brought to use of people.
Description
technical field [0001] The invention relates to the technical field of oil drilling and production, in particular to a butterfly valve used for oil drilling and a method of using the same. Background technique [0002] Butterfly valve, also known as flap valve, is a kind of regulating valve with simple structure, which can be used for on-off control of low-pressure pipeline medium. It is used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media, and it mainly plays the role of cutting and throttling on the pipeline. The disc-shaped butterfly plate rotates around its own axis in the valve body, so as to achieve the purpose of opening and closing or adjustment. Valves and butterfly valves not only have simple structure, small size, light weight, low material consumption, small installation size, small driving torque, simple and rapid operation, but also have good flow regulation functio...
