摘要： The objective is to provide a sealing device provided with an accumulated pressure relief function. In order to achieve the objective, a seal ring is combined with a back ring, and the back ring is comprised of a lip packing wherein one end of an annular base portion in the axial direction is provided with an inner lip and an outer lip, and the outer peripheral surface of the annular base portion is provided with an annular protrusion for setting a margin for the compression of the back ring in the radial direction. The outer lip is brought into close contact with a cylinder to seal fluid to be sealed, and is pushed by pressure accumulated in a space on the other end in the axial direction so that the outer lip is spaced from the cylinder to relieve the accumulated pressure. The annular protrusion is provided with a passage through which the accumulated pressure is introduced to the outer lip.

摘要： An object is to implement seal inspection with a simple structure and to enable the inspection to be performed with higher accuracy and in a shorter time than in the conventional case.
A seal inspection device includes: a first holder (11) including a port (101) surrounded by an inspection target (20), and a through hole connected to an outside-leak detection flow path (104); a second holder (12) holding the inspection target (20) between the first and second holders (11 and 12); an inspection-place sealing portion (30) forming, into a closed space, a space where the inspection target (20) is arranged, in cooperation with the first and second holders (11 and 12); a pressurization valve (111) connecting the port (101) to both a supply source of an inspection gas and an exhaust system; a detector for the inspection gas; a first measurement valve (121) connecting the detector to the port (101); and a second measurement valve (124) connecting the outside-leak detection flow path (104) to the detector.

摘要： Provided is a sealing device that can suppress deterioration of sealing properties due to plastic deformation (settling) of an outer circumferential lip. The sealing device is characterized by including a packing (10) made of resin having an outer circumferential lip (12) on an outer circumferential side with respect to an annular mounting groove (11) provided on a sealed fluid side and an inner circumferential lip (13) on an inner circumferential side with respect to the annular mounting groove (11), and a metal spring member (20) mounted in the mounting groove (11) and having an outer circumferential pressing portion (21) that extends radially outward and toward the sealed fluid side from a groove bottom of the mounting groove (11) and presses the outer circumferential lip (12) radially outward, and an inner circumferential pressing portion (22) that extends radially inward and toward the sealed fluid side from the groove bottom of the mounting groove (11) and presses the inner circumferential lip (13) radially inward. Among the outer circumferential lip (12) and the inner circumferential lip (13), a protrusion (13a) for preventing the spring member (20) from coming off is provided only on the inner circumferential lip (13).
