[0015] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0016] like Figure 1 and Figure 2As shown, the utility model proposes an automatic sampler for crude oil detection, including a sampling bottle 1, a sampling cover 2, a valve seat 3, a sampling structure 4 and a vacuum structure 5. The sampling cover 2 is threaded on the sampling bottle 1, the valve seat 3 is fixed on the sampling cover 2, the sampling structure 4 is fixed on the valve seat 3, the vacuum structure 5 is arranged on the valve seat 3, the sampling structure 4 includes a sampling tube 6, a valve seat 7, a sealing groove 8, a threaded rod 9 and a rubber plug 10, the sampling tube 6 passes through the valve seat 3 and is fixedly arranged, the valve seat 7 is wrapped on the sampling tube 6, the sealing groove 8 is arranged in the valve seat 7, the threaded rod 9 is threaded on the valve seat 7, and the rubber plug 10 is fixed on the threaded rod 9 and is slidably sealed in the sealing groove 8.

[0017] like Figure 1 and Figure 2 As shown, the vacuum structure 5 includes an air hole 11, a sealing chamber, a sealing gasket 13, a supporting spring 14, a sealing cover 15 and an air suction nozzle 16. The air hole 11 is arranged through the valve seat 3, the sealing chamber is arranged in the valve seat 3, the sealing gasket 13 is pasted to the bottom of the sealing chamber, the supporting spring 14 is arranged at the top of the sealing chamber, the sealing cover 15 is arranged on the supporting spring 14, and the air suction nozzle 16 is fixedly arranged through the valve seat 3.

[0018] like Figure 2 As shown, the sealing gasket 13 is arranged between the air hole 11 and the sealing cover 15 , and the supporting spring 14 is arranged between the sealing cover 15 and the valve seat 3 .

[0019] like Figure 2 As shown, the sealing gasket 13 is arranged in parallel with the sealing chamber, and the sealing groove 8 is arranged in parallel with the rubber plug 10.

[0021] like Figure 1 As shown, the sampling bottle 1 is set for sampling high hardness steel.

[0022] When using the device specifically, the user first installs the vacuum pump and connects it to the suction nozzle 16, and starts the vacuum machine to extract the air in the sampling bottle 1. At this time, the control pushes the sealing cover 15 through the air hole 11, and then the air is extracted through the suction nozzle 16. After extraction, the suction nozzle 16 is pulled out. At this time, the external air pressure is relatively large, and the air pressure in the sampling bottle 1 is relatively small. At the same time, the supporting spring 14 pushes the sealing cover 15 to squeeze on the sealing gasket 13, thereby closing the air hole 11 to prevent the outside air from entering the sampling bottle 1. When in use, the rubber tube is inserted into the sampling tube 6, and one end of the oil extraction pipe is inserted into the oil barrel, and then the threaded rod 9 is screwed to pull the rubber plug 10 upward in the blocking groove 8, thereby opening the valve port of the sampling tube 6. At this time, the pressure in the sampling bottle 1 is not negative, and the pressure difference is used to draw crude oil into the sampling bottle 1 through the oil extraction pipe on the sampling tube 6, thereby completing the sampling work and avoiding spilling and transfer. The above is the entire use process of the automatic sampler for crude oil detection.
