Abstract The invention discloses a natural gas sampling device, which is a left-right symmetrical structure and comprises: the tank body positioned in the middle of the natural gas sampling device and used for storing the natural gas; a pair of sealing rings used for sealing a joint of the tank body and end covers; a pair of end covers, wherein the end covers are connected with the tank body via threads and are sealed by the sealing rings therebetween and used for installing the lifting check valves; and a pair of lift check valves, wherein the lifting check valves are installed in the middle of the end covers by threaded connection, and external threads are milled at outer ends of the lifting check valves for being connected with an air source; and a pair of cleaning covers capped on the lift check valves at two ends and used for preventing the lift check valves from being operated in error. The sampling device is simple in structure, easy to produce and process, low in manufacturing cost, light in weight and convenient to operate in practice. It is suitable for mass use in a natural gas exploration and development process. 5 4 3 2 1 23 4 5
