Embodiment Construction

[0034] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the illustrated embodiment, with Figure 16 (Conventional Art) The same components shown are denoted by the same reference numerals. exist figure 1 and 2 1 , a pipe joint generally designated by reference numeral 100 has a socket 20 as a component on the filling device side and a plug 10 as a component on the nozzle side. Here, the longitudinal direction of the plug is in figure 1 and 2 are different. This is to make the overall configuration easier to see. In addition, in order to clearly show the internal structure of the socket 20, in figure 2 In, the prismatic housing 21 of the socket 20 is omitted (the socket main body: figure 1 ) and the upper cover 31 ( Figure 7 ). figure 1 and 2 A state in which the plug 10 and the socket 20 are connected to each other is shown. The overall cylindrical plug 10 has a plug main body 1 and a plug-side protruding ...

Abstract

Provided is a pipe joint capable of cutting off a hydrogen gas flow path immediately at an initial stage when a plug (nozzle-side member) is removed from a socket (filler-side member) to prevent release of escape gas. The pipe joint according to the present invention comprises: a cylindrical nozzle-side member having a shut-off valve, in which a passage is formed; and a cylindrical filling device-side member having a shut-off valve in which passages are formed, in which, when the nozzle-side member and the filling device-side member are connected to each other, the center axes of the passages of the nozzle-side member and the filling device-side member do not form the same straight line, and the center axes of the passages are offset without intersecting. The shut-off valves of the two members are opened so that the passages of the two members communicate with each other when the nozzle-side member and the filling device-side member are separated from each other, and the shut-off valves of the two members are closed when the nozzle-side member and the filling device-side member are separated from each other.

Description

technical field [0001] The present invention relates to a charging device for charging gas such as hydrogen used as fuel. More particularly, the present invention relates to a pipe joint for separating a filling device and a gas filling nozzle from each other in an emergency when filling gas with the filling device. Background technique [0002] For example, if Figure 15 As shown, for vehicle A using hydrogen as fuel, hydrogen gas is filled after a hydrogen filling station connects filling nozzle 202 attached to one end of filling hose 201 of hydrogen filling apparatus 200 and vehicle side filling port 203 to each other. Filling is performed while being controlled based on the maximum operating pressure of the hydrogen tank 204 mounted on the vehicle A. Here, for example, when the vehicle A is driven while charging hydrogen and the charging hose 201 is pulled, components such as the charging nozzle 202 and the charging hose 201 are damaged to inject hydrogen, making it a d...
