Embodiment 1

[0023] A kind of safe quick connector for loading and unloading of liquefied hydrocarbon tanker, such as Figure 1-3 As shown, it includes two parts: male head and female head, including two parts: male head and female head. The outer circumference of the male head is uniformly distributed with spiral grooves and set limit card slots, with a built-in stop valve; the female head and the tanker are fixed by flanges Installed on the tank car, the tail of the female head is fixed and installed on the front end of the liquefied hydrocarbon crane pipe through the conical pipe thread. The female head is equipped with an ultra-short ball valve, a relief ball valve, and a flange seat. Roller, with a ball groove in the middle section, a hand wheel at the tail, a ball groove on the inner circumference of the female head, connected to the male head through balls, a built-in stop valve, and a universal joint at the tail; when connecting, the female head roller is in the male head spiral gro...

Abstract

The invention relates to a liquefied hydrocarbon tank car loading and unloading safety quick coupling. The problems that in the prior art, a coupling is likely to be disengaged and prone to leakage, quick cutting cannot be achieved, and safety is poor are mainly solved. The liquefied hydrocarbon tank car loading and unloading safety quick coupling comprises a male end and a female end, the femaleend and the tank car are fixedly installed on the tank car through flanges, the tail of the female end is fixedly installed at the front end of a liquefied hydrocarbon crane pipe through threads of aconical pipe, the female end is provided with an ultra-short ball valve, a tapping ball valve and a flange base, spiral grooves are evenly distributed in the outer periphery of the male head, a stop valve is arranged inside, the female head of the quick coupling is provided with a locking mechanism, a roller is arranged at the head, a ball groove is formed in the middle section, a hand wheel is arranged at the tail, a ball groove is formed in the inner periphery of the female head, the stop valve is arranged inside through connection of the ball and the male head, and a universal joint is arranged at the tail, so that the problems are solved, and the quick coupling can be used for liquefied hydrocarbon tank car loading and unloading.

Description

technical field [0001] The invention relates to a quick connector of a safe loading and unloading type for a liquefied hydrocarbon tanker. Background technique [0002] Liquefied hydrocarbons in liquefaction plants are generally loaded and unloaded by tank trucks, and the quick joints on the fluid loading arm (crane tube) are used to connect with the quick joints on the tank trucks to realize a closed loading and unloading process. Therefore, the reliability of the quick joints is related to the loading and unloading of liquefied hydrocarbons. safe or not. On June 5, 2017, a liquefied gas tanker in the liquefied hydrocarbon loading and unloading area of ​​Jinyu Petrochemical, Lingang District, Linyi City, Shandong Province exploded during loading and unloading operations, resulting in 10 deaths and 9 serious injuries. The cause of the preliminary investigation was liquefied hydrocarbons during loading and unloading. After leaking and gasifying rapidly, it will explode viole...
