Abstract

The invention discloses a loading / unloading arm and tank opening connecting device. A gas collecting cylinder and a cylinder are mounted on a cover plate; an exhaust flange is arranged on the side surface of the gas collecting cylinder, and is used for connecting with a gas recovery channel; a cylinder cover is arranged above the gas collecting cylinder; a groove is formed in the upper surface of the cover plate; the gas collecting cylinder is mounted in the groove; the cover plate is provided with a thread hole; the thread hole is used for mounting the cylinder; a through hole is formed in middle of the cover plate; a flow passing pipe penetrates through the through hole; a gap is formed between the cover plate and the outer peripheral surface of the flow passing pipe, and is connected with the gas collecting cylinder; the flow passing pipe is provided with a fan-shaped plate in the contacted place with the lower surface of the cover plate; an external thread is arranged at the upper part of the flow passing pipe; and the cylinder cover can be tightly pressed through a round nut mounted on the external thread. The device is simple in structure and convenient in manufacturing, reduces the production cost, is high in adaptability, can be applied to truck loading of most liquid types and tan openings with different sizes, improves the reliability of similar structures, improves the safety of truck loading of dangerous and harmful fluids, and reduces environmental pollution.

Description

technical field [0001] The invention belongs to the technical field of fluid loading and unloading, in particular to a connecting device between a loading and unloading arm and a tank mouth. Background technique [0002] This patent relates to the technical field of fluid loading and unloading, especially the loading and unloading of highly volatile, flammable, explosive, or environmentally hazardous liquids; the loading and unloading arm used for loading and unloading volatile liquids such as gasoline has a vertical pipe at its end. There is a conical sealing cap on the top, and the vertical pipe and the conical sealing cap together constitute the connection structure between the loading and unloading arm and the tanker. The vertical pipe is extended to the bottom of the tank by telescopic means, the loading and unloading arm is loaded with liquid into the tank car through the vertical pipe, and the conical sealing cap is closely matched with the tank mouth of the tank car ...
