Compared with the prior art, the beneficial effects of the utility model reside in that: when the device is used, the sliding ring is placed at a sampling port of the tank car, so that the functions of stabilizing the sampling pipe and indicating the sampling depth are achieved; the sampling pipe is placed perpendicular to the length direction of the tank car, an operator slowly puts the sampling pipe down into the tank, the liquid inlet valve plate is jacked open by liquid in the sliding process, and samples at the depth of each liquid level can enter the sampling pipe, so that the collected samples are more uniform and representative; and need not to set up control switch at the sampling pipe lower extreme, rely on the gravity of intraductal liquid to close the feed liquor valve plate when lifting, realize sealed, sample easy operation, reliable.
The utility model discloses a preferred scheme does:
the feed liquor valve plate comprises a center fixing plate, a rubber outer ring and a connecting shaft, the rubber outer ring is connected to the outer edge of the center fixing plate, the upper surface of the center fixing plate is connected with one end of the connecting shaft, and the other end of the connecting shaft is rotatably connected to the inner bottom surface of the sampling pipe.
The sampling tube is characterized by further comprising an end cover, wherein the end cover is hinged to the upper end of the sampling tube and covers the upper port of the sampling tube. In order to prevent the sample from being scattered in the lifting process of the sampling pipe, an end cover is arranged at the upper port of the sampling pipe, and the temporary sealing effect is achieved.
The outer diameter of the slip ring is larger than the diameter of the sampling port of the tank car.
The lateral wall of sampling pipe is provided with the scale, and zero scale setting is at the sampling pipe lower extreme.

Detailed Description
The present invention will be described in detail with reference to the following embodiments in order to fully understand the objects, features and functions of the present invention, but the present invention is not limited thereto.
As shown in figure 1 and figure 2, the utility model provides a pair of sampling device on liquid dichloroethane tank car comprises sampling pipe 1, sliding ring 2, feed liquor valve plate 3 and end cover 4 etc.. Sampling pipe 1 is the upper end uncovered, the lower extreme has the cylindric structure of bottom plate, and sampling hole 5 has been seted up at sampling pipe 1's bottom plate center, is fixed with a pair of otic placode on the sampling pipe bottom plate inner wall of sampling hole 5 peripheries, is connected with the axis of rotation between the otic placode, and the axis of rotation is connected with the feed liquor valve plate.
As shown in fig. 3 and 4, the liquid inlet valve plate is composed of a connecting shaft 6, a central fixing plate 7 and a rubber outer ring, one end of the connecting shaft 6 is connected with the rotating shaft, the other end of the connecting shaft 6 is connected with the surface of the central fixing plate 7, and a circle of the rubber outer ring is fixed on the outer edge of the central fixing plate 7. When the liquid inlet valve plate 3 is closed, the central fixing plate 7 completely covers the sampling hole 5, and the rubber outer ring plays a role in sealing; when the liquid inlet valve plate 3 is opened, the central fixing plate 7 and the rubber outer ring are separated from the sampling hole 5, so that a sample enters the sampling pipe 1.
The lateral wall of sampling pipe 1 is provided with two symmetrical spout 8 along sampling pipe length direction, and the upper and lower end of sampling pipe 1 is not reachd at the both ends of spout 8, therefore 8 both ends of spout all have the shutoff. The sampling tube 1 outside cover is equipped with the sliding ring 2, and the sliding ring 2 inner circle is fixed with symmetrical lug 9, and lug 9 dress is in spout 8 and can slide from top to bottom along spout 8. The external diameter of sliding ring 2 is greater than the diameter of tank car sample connection, guarantees that sliding ring 2 card is in the tank car sample connection outside, and the steady support sampling pipe 1 alleviates operating personnel's the operation degree of difficulty. The side wall of the sampling tube 1 is provided with scales from the lower end surface to the upper end surface. And in the process of sliding down the sampling tube 1, the sampling depth is indicated by taking the sliding ring 2 as a pointer. During the equipment preparation, the sliding ring 2 adopts the metal material, reserves the opening, and the sliding ring 2 welds after overlapping to 1 spout 8 positions of sampling pipe.
Because the length of the sampling pipe 1 is larger than 1m, and the pipe diameter is less than or equal to 5cm, the upper port is easy to spill samples in the process of extracting and transferring the sampling pipe 1, therefore, the upper end of the sampling pipe 1 is connected with an openable end cover 4 (a rotary connection mode, a chain connection mode and the like can be adopted), when the sampling pipe 1 needs to be lifted up after sampling is completed, the end cover 4 is covered, then the sampling pipe 1 is lifted up from a tank car, and when the sliding ring 2 reaches the lower end of the sliding groove 8 for plugging, the sampling pipe 1 is lifted up together with the sliding ring 2.
The using method comprises the following steps: when the sampling pipe sinks, the liquid inlet valve plate is opened, the liquid enters the sampling pipe, the end face of the sampling pipe sinks continuously, the liquid enters the sampling pipe when the sampling pipe contacts the liquid, and the representativeness of the sample is guaranteed. After the sampling pipe reachd the tank car bottom, cover the end cover, operating personnel lifts the sampling pipe, takes the sliding ring together, changes and puts appointed lofting district, and the sampling pipe of keeping flat, sampling pipe upper port are located directly over the collection sample bucket, open the end cover, discharge the intraductal liquid of sampling.
Finally, it is noted that: the preferred embodiments of the present invention have been shown and described, and it will be understood that modifications and variations may be made by those skilled in the art without departing from the scope of the invention.
