Problems solved by technology

[0002] With the advent of the adjustment of the global energy structure, the construction of domestic liquefied natural gas (LNG) receiving stations, loading and unloading stations, and vehicle and ship filling stations is advancing by leaps and bounds. It has become a key issue to realize fast and safe connections in the process of LNG receiving, unloading and filling. The existing connection methods are slow to install or unsafe, and ultra-low temperature fluids (LNG, liquid nitrogen, liquid oxygen, liquid hydrogen, etc.) The loading and unloading flange interface cannot be opened quickly due to ice formation

Abstract

The invention discloses an ultralow temperature vacuum insulation quick connector and a production method thereof. The connector comprises a pull rod, a vacuum cavity, a first outer pipe, a second outer pipe, a third outer pipe, a piston rod, a first oil orifice, a cylinder and the like. The pull rod is integrated with a jaw. The pull rod can be connected with a piston pin through a connecting shaft. The vacuum cavity is located among the first outer pipe, the second outer pipe, the third outer pipe and an inner corrugated pipe. The first oil orifice is located at the front end of the cylinder. A second oil orifice is located at the rear of the cylinder. The cylinder is connected with the piston rod. A vacuum opening is connected with the third outer pipe and communicated with the vacuum cavity. A counter flange and a connecting flange are welded with two ends of the inner corrugated pipe respectively. A support ring is located in the vacuum cavity between the inner corrugated pipe and the third outer pipe. A guide plate and a guide rod are welded to an annular rotator and fixed on the first outer pipe. By the ultralow temperature vacuum insulation quick connector, fast and safe connection and separation of a pipeline or a loading arm with a tank-truck or a LNG (liquefied natural gas) ship during ultralow-temperature liquid loading and unloading are achieved.

Description

technical field [0001] The invention relates to a connector, in particular to an ultra-low temperature vacuum heat insulation quick connector and a manufacturing method thereof. Background technique [0002] With the advent of the adjustment of the global energy structure, the construction of domestic liquefied natural gas (LNG) receiving stations, loading and unloading stations, and vehicle and ship filling stations is advancing by leaps and bounds. It has become a key issue to realize fast and safe connections in the process of LNG receiving, unloading and filling. The existing connection methods are slow to install or unsafe, and ultra-low temperature fluids (LNG, liquid nitrogen, liquid oxygen, liquid hydrogen, etc.) The loading and unloading flange interface cannot be opened quickly due to ice formation. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an ultra-low temperature vacuum insulated quick connect...
