Problems solved by technology
[0003] In the field of oil production, the gate valve is an important part of the pipeline. At present, most of the valves on the pipeline are placed in the valve well, which will increase the construction cost, and it is inconvenient to open and maintain, which is not conducive to popularization and application. Light source, if you want to find the valve in the dark at night, you have to use the electric light
It is realized by the lighting of an external light source such as a torch, which brings inconvenience to the valve used in low brightness and dark light

The invention relates to a deeply-buried type luminous valve and relates to the technical field of oil field oil recovery. The valve is composed of a valve body (1), a pressing cap (2), a flange (3), a protective sleeve (4), a lengthening rod (5), a valve rod (6), a hexahedron (7) and a luminous material layer (8). The pressing cap (2) is arranged at the upper end of the valve body (1), the flange (3) is arranged between the pressing cap (2) and the protective sleeve (4), the lengthening rod (5) is arranged in the protective sleeve (4), the lower end of the lengthening rod (5) is connected with the valve rod (6), the hexahedron (7) is arranged at the upper end of the lengthening rod (5), and the luminous material layer (8) is arranged on valve body (1). The valve is simple in structure, reduces construction cost, is convenient to open and maintain, capable of emitting light in the dark for a long time and long in service life, and a special lighting device does not need to be installed.
Description
Technical field: [0001] The invention relates to the technical field of oil field recovery, in particular to a deep-buried valve with night light. Background technique: [0002] The valve is a control component in the fluid delivery system. It has functions such as cut-off, adjustment, flow diversion, backflow prevention, pressure stabilization, flow diversion or overflow pressure relief. It is used as a valve in the fluid control system to control the direction, pressure, and flow of the fluid. A valve is a device that makes or stops the medium (liquid, gas, powder) in piping and equipment and controls its flow, ranging from the simplest shut-off valve to various valves used in extremely complex automatic control systems, its varieties and specifications Quite a variety, valves can be 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. Valves are also divided into cast iron...
