Apparatus for checking the set pressure of a safety valve

Image Number 2 for United States Patent #4527415.

The apparatus for checking the set pressure of a safety valve (300) comprises: a first tank (100) filled with a first fluid (110) at a pressure less than the set pressure, and connected to the fluid inlet tubing (310) of the valve; a second tank (200) filled with a second fluid (210) at a pressure greater than the set pressure; means (410) for rapidly putting the two tanks into communication with each other; and means (500, 510, 520) for simultaneously measuring the pressure in the fluid inlet tubing and the displacement of the valve plate.
