Abstract:
1. A socket structure used by connecting the socket structure to a plug of a connector disposed at an outlet of a vessel for taking a fluid out of the vessel for transfer, the socket structure comprising: a valve mechanism; a socket body having a channel for the fluid, and a plurality of parallel gas channels disposed concentrically about the channel for the fluids which are fluidly coupled to the vessel, the channel for the fluid having a length which is substantially the same as a length of the plurality of parallel gas channels; and a sleeve in which the socket body is disposed along a central axis thereof and which is disposed so as to be slidable in an axial direction on an outer circumferential surface of the socket body, the socket structure being configured to be screwed and secured by inserting and connecting an entrance of the channel that opens at a lower end of the socket body to a plug exit that opens at an upper end of the plug and then rotating the sleeve while sliding the sleeve downward so that a sleeve thread portion is screwed into a female thread portion which is provided on the plug, wherein the valve mechanism includes a valve element, a valve shaft which is directly coupled to the valve element, and a valve-opening/closing mechanism which is directly coupled to the valve shaft, wherein the valve element reciprocates along a central axis of the channel of the socket body, and wherein the plurality of parallel gas channels and the fluid channel are integrally formed in the socket body.
