Abstract
A pipe connector for a high-pressure fluid pipe comprises a socket and a plug. The socket includes a housing having a first end portion connected to a high-pressure fluid source, a second end portion receiving a plug, and a bore formed of a valve chamber located on the first end portion side and a plug hole located on the second end portion side, the bore connecting the first and second end portions. The housing includes a valve seat and a valve body disposed in the valve chamber, a sealing ring for sealing the gap between the outer peripheral surface of the valve body and the inner peripheral surface of the plug hole, and a passage adapted to connect the bore portion between the valve seat and the sealing ring to the bore portion on the second end portion side with respect to the sealing ring when the valve body is separated from the valve seat. The plug has a fluid passage capable of communicating with the pipe and at least one radial through hole adapted to communicate with the fluid passage when the plug is inserted in the plug hole. When the plug is inserted into the plug hole of the housing, the valve body is separated from the valve seat, so that a high-pressure fluid flows through the passage of the housing and the through hole and the fluid passage of the plug.
