Petroleum liquid sampling device favorable for sampling inspection

Abstract

The invention discloses a petroleum liquid sampling device favorable for sampling inspection.The petroleum liquid sampling device comprises a bag, one end of the bag is connected with an input pipe, the inner side of the free end of the input pipe is provided with an internal thread, the input pipe is in adaptive connection with a funnel connecting pipe through the internal thread, and the funnel connecting pipe is provided with a pipe cap.The bag is further provided with an output hole, an output pipe is inserted in and connected with the output hole, and the tail end of the output pipe is provided with an expansion connecting end.The funnel connecting pipe is installed on the input pipe, and a funnel-shaped opening of the funnel connecting pipe structure can solve the problem of adding petroleum of a large volume.The output hole is formed, the petroleum flows out through the output pipe connected with the output hole, and the problem that samples are directly extracted from the sampling device and the petroleum is attached to a sampling bag is solved.A medicine injection connection port is adopted and is a plastic cylindrical cavity, the shape of an insertion cover is adaptive with the inner side structure of the medicine injection connection port while a bag in the prior art has no such functional structure arrangement, and the petroleum liquid sampling device is favorable for adding a corresponding agent for pretreatment.

Description

technical field [0001] The invention relates to petroleum mechanical equipment, in particular to a petroleum liquid sampling device which is beneficial to sampling inspection. Background technique [0002] The oil sampling device is a structure for sampling and collecting oil in the process of oil exploitation. The commonly used sampling and collection device is a plastic bag, which has the characteristics of light weight, high strength, and corrosion resistance. It can realize the function of storing petroleum liquid, but there are some defects. When testing and sampling multiple indicators such as temperature and softening point, the sampling volume is relatively large, and the input port of the existing sampling bag is small, which is not convenient for adding the sampled oil; at the same time, when people take out the oil in the sampling bag, it is easy to put The oil sticks to the sampling bag, which cannot be reused and requires constant replacement of the collection ...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: the input port caliber of the existing collection bag is small and it is inconvenient to add a large volume of oil; when the oil in the sampling bag is output for inspection, it is easy to adhere to the sampling bag, causing contamination of the sampling bag , the problem that it can only be used once, a petroleum liquid sampling device that is beneficial to sampling inspection is now provided. By setting the input structure of the sampling device, a funnel connecting pipe is installed on the input pipe, and the funnel-shaped inlet of the structure of the funnel connecting pipe can be Solve the problem of adding large volumes of oil; set the output hole, the oil will flow out through the output pipe connected to the output hole, and solve the problem of directly extracting samples from the sampling device and sticking the oil to the sampling bag
