Title:
PRESSURE MEASURING INSTRUMENT
Document Type and Number:
Japanese Patent JP3475212
Kind Code:
B2
Abstract:
PURPOSE: To reduce contamination due to the leakage of a hydraulic fluid and its loss by selectively connecting a manometer to reduce the number of the measurement when measuring the pressure at a plurality of points.
CONSTITUTION: A pressure measuring instrument has an attachment body 20 mounted to a nipple B of a pressure detection part C and a manometer 36 connected to it. A second valve 25 for preventing the pressure at the manometer side from being leaked externally is provided in the attachment body 20 and a protruding part 30 projecting from a nipple B is inserted when mounting the attachment body 20 to either nipple B and a first check valve 15 incorporated into it is opened and then the pressure at a pressure detection part is led to the manometer 36 via a first check valve 15, an introducing path P, and a second check valve 25. The protruding part 30 may be provided at the attachment body 20 or a valve body 27 of the second check valve 25. The attachment body 20 is clamped to the nipple B by a mounting member 34.
