Problems solved by technology

At present, there are only quick connectors for normal temperature medium transportation on the market, and the loading and unloading of LNG products is different from normal temperature medium. Since the temperature of LNG medium is -162 degrees, the pipes and connecting flanges usually freeze during loading and unloading. Therefore, the commonly used quick connectors cannot meet the working conditions of LNG product loading and unloading.
[0003] Since there are no quick connectors for loading and unloading low-temperature media currently on the market, some users tried to replace them with normal temperature quick connectors, but found that the normal temperature quick connectors are connected by male and female heads of single-layer pipes, and the conventional connector connection method is too compact and always ends up Frozen to death, unable to break free

Abstract

The invention discloses an LNG special quick connector. The LNG special quick connector comprises a female connector, a sealing ring and a male connector; the female connector comprises a female connector connecting clamping head, a female connector connecting part used for dismountably connected with an external pipeline, and a female vacuum connecting pipe used for connecting the female connector connecting clamping head and the female connector connecting part; the male connector comprises a male connector connecting clamping head, a threaded pushing ring and a male connector vacuum connecting pipe; the sealing ring is embedded in the interior of the female connector connecting clamping head; the male connector connecting clamping head can be axially docked with the female connector connecting clamping head in an embedded and limited manner; the threaded pushing ring is dismountably and axially fixed to the male connector vacuum connecting pipe in a limited manner and matched with the rear end of the male connector connecting clamping head. According to the technical scheme, the connecting can be realized in the way of axially positioning the male connector connecting clamping head and the female connector connecting clamping head and then screwing in the threaded pushing ring and finally pushing the male connector vacuum connecting pipe tightly onto the pre-installed sealing ring.

Description

technical field [0001] The present invention is applied to the loading and unloading process of liquefied natural gas (LNG) products. When loading and unloading vehicles or ships or fueling, connect the female joint of this product with the storage tank interface of the loaded vehicle or ship, and connect the male joint with the transportation or The filling pipeline interface is connected, and the male and female heads can be quickly connected and expressly separated when the connection is needed. LNG special quick connector. Background technique [0002] According to reports in the industry, there is currently no quick connector suitable for the working conditions in this field, and flange connections are generally used. At present, there are only quick connectors for normal temperature medium transportation on the market, and the loading and unloading of LNG products is different from normal temperature medium. Since the temperature of LNG medium is -162 degrees, the pipe...
