Filed: 1988-08-19
Abstract: PURPOSE: To perform sealing with reliability by putting inner and outer elastomeric seal rings between upper and lower actuation rings, expanding and shrinking the elastomeric seal rings by an axial thrust, and flexibly bending metal seal lips. CONSTITUTION: A sealing device 80 is constituted with an upper actuation ring 100, a sealing member 102, and a lower actuation ring 104, which are respectively made to rotate and to move in axial directions within limited regions. On a ring-shaped body part, the member 102 has inner and outer elastomeric seal rings, which respectively form elastic seals between an inner bore wall 15 of a wellhead housing 10 and an outer sealed face 60 of a casing hanger 22. When fluid pressure is added, the rings 102, 104 expand and shrink two sets of inner and outer elastomeric seal rings to contact closely with walls 15, 60 respectively, preventing the leakage of the pressurized fluid, which enables pressure- energization up to full working pressure.

In the case of sample measurement, the shutter 18 (16) is opened (closed), and the optical fiber 38 sends the sample beam to the sample, and an optical fiber 40 receives the sample beam from the sample. At the time of the measurement of transmissivity (reflectance), the sample is arranged between the input and output terminals (on the same side) of fibers 38, 40.  In either case, the light quantity of the sample beam received by the optical fiber 40 and detected by the detector 24 through the cube 22 is compared with the reference value by the unit 30 to quantitatively determine the density of the specimen to be examined in the sample.
