FEMALE JOINT HAVING SAFETY FUNCTION
Document Type and Number:
WIPO Patent Application WO/2014/050929
Kind Code:
A1
Abstract:
[Problem] To provide a female joint in which the male joint is prevented from being blown away by fluid pressure when the connected male joint is detached. [Solution] This invention is provided with: a main joint body (20) having a fluid channel (32) and adapted so as to receive the male joint from the front end part; and a valve member (40) provided to the main joint body so as to intersect the fluid channel. The valve member has an opening and is capable of being displaced between an open position and a closed position along a direction intersecting the fluid channel. In the open position, the front-end-part side and the rear-end-part side of the fluid channel communicate with each other through the opening. In the closed position, the opening is located outside the fluid channel, and the front-end—part side and the rear-end-part side are closed from each other. This invention has a purge channel (48) configured so as to communicate between the front-end-part side of the fluid channel and the atmosphere outside the female joint when the valve member is in the closed position.
