Oil inlet device of oil storage tank

Abstract

The invention discloses an oil inlet device of an oil storage tank. The oil inlet device of the oil storage tank comprises an oil inlet pipeline (5) which is horizontally arranged, wherein the oil inlet pipeline (5) is connected with one end of a main pipe of a tee joint (7) through a reducer (6), and the other end of the main pipe of the tee joint (7) is provided with a flange (12) and a flange cover (13). A buffer guide plate (10) is arranged in the main pipe of the tee joint (7), the buffer guide plate (10) is arranged above a branch pipe of the tee joint (7), and a spring (11) is arrangedbetween the buffer guide plate (10) and the flange cover (13). An outlet of the branch pipe of the tee joint (7) is downward and is used as an oil outlet (9). An anti-impact base plate (14) is arranged below the oil outlet (9), and the anti-impact base plate (14) is fixed on a soleplate (3) of the oil storage tank. The oil inlet device can be used for the oil storage tank of an oil storage and transportation system of a petrochemical enterprise.

Description

technical field [0001] The invention belongs to the field of oil storage and transportation systems for petrochemical enterprises, and relates to an oil inlet device for an oil storage tank. Background technique [0002] In the oil storage and transportation system, the oil enters the oil storage tank through the oil outlet of the oil inlet pipeline. Controlling the flow rate of the oil outlet is an important measure to ensure the safe production and operation of the oil storage tank in petrochemical enterprises. According to the requirements of the national standard GB13348-2009 "Electrostatic Safety Regulations for Liquid Petroleum Products", during the filling process, the oil should be prevented from flying and splashing. In addition, when there is obviously an incompatible second phase in the oil inlet pipeline, the oil flow rate should be controlled below 1 m / s to prevent electrostatic hazards. There are generally two types of existing oil inlet devices for oil storag...
