Petroleum liquid transparent glass sampler and sampling method thereof

Abstract

The invention relates to a petroleum liquid transparent glass sampler and a sampling method thereof, belonging to the technical field of petrochemical industry, and has the characteristics of multi-function, good versatility, accurate sampling fixed point, convenient operation, clean environment and no pollution, and the like. It is composed of a container part, a valve control mechanism and a tape disc; the container part includes a screw rod, a base, a container, a connecting pipe, a gasket, an upper cover, a valve cover, an ear handle and a handle. The valve control mechanism includes a cock, a valve sleeve, a valve stem, a valve plate, a positioning nut, a push rod, a hook, a spring and a valve cap. The structure of the ruler belt reel is composed of two parts: fixed and rotating. The fixed part includes the left fixed ring, inner fixed ring, pulley shaft, pulley and ruler door lever; the rotating part includes the right moving ring, left rail ring, warehouse bottom ring, Spacers, nuts, left rail ring and right moving ring form a ruler belt bin, the outer circle of the bottom ring of the bin is used as the bottom plate of the ruler belt bin, the inner circle of the left rail ring is inserted into the pulley groove as a rotating track, and the ruler door rods are distributed around the left ring.

Description

technical field [0001] The invention relates to a petroleum liquid transparent glass sampler and a sampling method thereof, belonging to the technical field of petrochemical industry, and has the characteristics of multi-function, good versatility, accurate sampling fixed point, convenient operation, clean environment and no pollution, and the like. Background technique [0002] The storage and transportation of oil products is often carried out in a closed environment, so there are many factors that affect the quality of oil products, such as: unclean storage and transportation equipment containers pollute oil products; misadjusted oil products during shipment; Replacement of oil products; oxidative deterioration of inferior oil products, etc., will lead to changes in the color, clarity, viscosity and other appearance of the oil products, resulting in some obvious visible features. Looking back at previous major automobile oil quality accidents, most of them were caused by ...

Problems solved by technology

[0003] Currently commonly used petroleum liquid samplers, one is a spotting sampler that is specially used to take samples at various points between the outlet liquid level of the oil storage container and the top liquid level, and the other is a bottom sampler that is specially used to take samples from the bottom of the oil storage container. The following three problems: first, it cannot be used universally; second, the casing is opaque, and it is inconvenient to check the appearance quality of the oil at the sampling site; third, the sampling rope must be used, which is troublesome for dirty and messy

The pointing sampler must use a plug, and problems often occur during use: if the plug is too tight, it is not easy to open, and the sampling rope is pulled violently, which will easily cause excessive disturbance; and when the plug is too loose, the sampling point will not be reached. It will open the sample by itself, and the upper sample has leaked into the sampler; these problems are sometimes difficult to find, resulting in the lack of representativeness of the samples taken
