A prevention and control device and method for avoiding wrong oil unloading

Abstract

The invention discloses a prevention and control device and method for avoiding wrong oil unloading. The end face is rotatably connected with a sealing cover plate, and the interior of the main body of the prevention and control device is provided with a baffle plate, which divides the inside of the main body of the prevention and control device into a control area and a liquid injection area, and the bottom of the main body of the prevention and control device is provided with a baffle plate. An infusion tube, one end of the infusion tube is communicated with the liquid outlet, a first spring is arranged in the control area, and the other end of the first spring is elastically connected with a constant volume chamber, and the constant volume chamber passes through the first spring. The spring is elastically connected inside the control area, and the lower end surface of the constant volume bin is fixedly connected with a control valve plate. The device realizes that the oil is unloaded by sampling a large amount of the input oil and driving the control valve to open and close through the density. If the product is wrong, it is difficult to raise.

Description

technical field [0001] The invention relates to the technical field of supervisory devices, and in particular, to a prevention and control device and method for avoiding wrong oil unloading. Background technique [0002] At present, the oil products of most gas stations are stored in different ground tanks, and the oil discharge ports of various oil products are concentrated in a fixed oil discharge tank. The Chinese oil products are the same. When the gas station receives and unloads the oil products, the mixed oil caused by the wrong pipeline connection is one of the main reasons for the oil product quality accident at the gas station. The main thing is to distinguish the oil discharge ports of gasoline and diesel with the female and male quick joints respectively, and use hoses with different interfaces for docking the unloading and diesel oil. However, because the interface between the hose and the connection end of the oil tanker is common to all warehouses, and The va...
