Oil products sampler

Abstract

An oil product sampler consists of sampler body and static current suppressing sleeve sheathed on sampler body. It features that metal bottle of sampler or metal weight of dipper stick is used as sampler body and static sub conductor is applied as material of static current suppressing sleeve for preventing sampler from static discharge effectively.

Description

technical field [0001] The invention relates to an improvement in the structure of a sampling and oil measuring appliance used for petroleum and petroleum products. Background technique [0002] During the processing and storage and transportation of petroleum and petroleum products, the oil products in storage tanks or tank cars, operating tools and human bodies will generate and accumulate a large amount of static electricity, causing static electricity hazards, causing explosions and fire accidents, and endangering people's lives. Property poses a great threat. [0003] In order to grasp and understand the quality and oil storage capacity of oil products in storage tanks, tank trucks and other tanks, people have to use metal samplers or dipsticks to obtain corresponding data. However, in the process of putting in and pulling the sampler or oil dipstick, when the resistance of the sampling rope fails, is not grounded, or does not work according to the static requirements,...

Problems solved by technology

However, in the process of putting in and pulling the sampler or oil dipstick, when the resistance of the sampling rope fails, is not grounded, or does not work according to the static requirements, it is inevitable that the electrification of the sampler or oil dipstick, and The tank wall, the floating plate in the tank or the oil surface are close to each other and cause electrostatic discharge, resulting in an explosion accident in sampling / testing

[0004] In response to the above problems, the current preventive measures mainly include two aspects: one is to allow the oil in the tank to stand for at least 30 minutes before sampling / testing operations, but this measure requires timely control of oil blending operations or refueling of group vehicles When the tonnage of the oil product is high, it is impossible to operate according to the static requirements; even if the static operation is allowed in the operation process, the static time is often not easy to grasp, or the occurrence of human phenomena such as illegal operations also makes this preventive measure practical. The effect appears to be unreliable

The second is to connect the sampler or oil dipstick to the special ground terminal on the tank with a static conductive rope to discharge static electricity, but the validity period of the static conductive rope is very limited. For example, most products need to be replaced in time within three months of shelf life. It is often used for more than half a year, or even a year, two years or longer, so that the metal sampler and the detection tool form an isolated conductor, which is very prone to spark discharge and cause hazards.
