Embodiment Construction

[0050] Hereinafter, embodiments of the present invention will be described with reference to the drawings. First, refer to figure 1 , figure 2 The first embodiment will be described. exist figure 1 Among them, the safety joint of the first embodiment, which is indicated by the reference numeral 100 as a whole, includes a nozzle-side member (plug) 10 and a filling device-side member (socket) 20 .

[0051] The plug 10 has a plug body 11 and a plug protrusion 12 integrally formed with the plug body 11 . The plug body 11 has, for example, a cylindrical shape, and a narrowed portion 11d having a small diameter is formed in the substantially center thereof. The plug protruding portion 12 is formed, for example, in a cylindrical shape with a diameter smaller than that of the plug body 11, and is opposite to the side away from the plug body 11 ( figure 1 , figure 2 The center is the left side) the end is chamfered.

[0052] A second flow path 14 is formed in the plug body ...

Abstract

The present invention provides a safety joint capable of immediately cutting off a hydrogen gas flow path at an initial stage in which a plug serving as a nozzle-side member is separated from a socket serving as a filling device-side member, thereby preventing emission of exhaust gas. The safety joint is composed of a cylindrical nozzle-side member and a cylindrical filling device-side member, wherein a flow path is formed in the nozzle-side member, and the shutoff valve is opened when the nozzle-side member is connected with the filling device-side member; and a flow path is formed in the cylindrical filling device-side member, and the filling device-side member can be connected with the nozzle-side member.

Description

technical field [0001] The present invention relates to a filling device for filling a gas such as hydrogen used as a fuel. In more detail, this invention relates to the pipe joint which isolate|separates a filling apparatus and the nozzle for gas filling when an emergency arises when a gas is filled with this filling apparatus. Background technique [0002] For example, in vehicle 400 running on hydrogen as fuel, as Figure 8 As shown, a filling nozzle 202 provided at the tip of a filling hose 201 of a hydrogen filling device 200 installed in a hydrogen filling facility is connected to a vehicle-side filling port 203 to fill with hydrogen gas. This filling is performed while being controlled according to the maximum operating pressure of the hydrogen tank 204 mounted on the vehicle 400 . Here, for example, when the filling hose 201 is pulled due to the movement of the vehicle 400 during filling, equipment such as the filling nozzle 202 and the filling hose 201 is damaged a...
