Problems solved by technology

[0003] However, the existing filling device is usually provided with an elastic member and a sealing cover in the housing, and then the filling device squeezes the sealing cover and then fills LNG; after the filling is completed, the elastic member is pushed The sealing cover is moved upwards to realize the sealing, but the extrusion of the sealing cover through the liquid filling device will cause the sealing cover to loosen, resulting in a decrease in sealing performance, resulting in a lower sealing performance of the filling device

Abstract

The invention discloses a filling device applied to a liquefied natural gas (LNG) bottle. The filling device comprises a housing composed of a housing inlet and a sealing surface, an outlet joint, a valve element assembly and an elastic part, wherein the housing inlet is formed in the front end of the housing, and the sealing surface is arranged inside the housing; the outlet joint is arranged at the tail end of the housing, and the outlet joint is matched with an inlet of the LNG bottle; the valve element assembly comprises a hoop, a sealing part and a valve element; the hoop is arranged in the front of the inside of the housing; the sealing part and the valve element are mounted in the hoop, and the sealing part is matched with the sealing surface; the elastic part is disposed in the housing, one end of the elastic part is fixed in the housing, and the other end of the elastic part is connected with the valve element assembly. By means of the filling device applied to the LNG bottle, the sealing performance of the filling device can be improved.

Description

technical field [0001] The invention relates to the technical field of LNG (liquefied natural gas, liquefied natural gas), in particular to a filling device applied to LNG bottles. Background technique [0002] With the shortage of oil resources, natural gas has been widely used as a new energy source, and the application of LNG in new energy vehicles has gradually expanded. The demand for LNG supporting products has also increased year by year. Quick connection to refuel LNG vehicles requires higher reliability of the filling device. [0003] However, the existing filling device is usually provided with an elastic member and a sealing cover in the housing, and then the filling device squeezes the sealing cover and then fills LNG; after the filling is completed, the elastic member is pushed The sealing can be achieved by moving the sealing cover, but the extrusion of the sealing cover by the liquid filling device will cause the sealing cover to loosen, resulting in a decrea...
