A shock responsive fluid valve assembly capable of automatically closing a fluid
valve in response to earthquake forces or other shock forces of a predetermined
magnitude. The shock responsive valve assembly has a flow control mechanism having
a cradle that holds a movable ball in a recess at a point perpendicular in relation
to a horizontal base plate, where the ball can be rotated 360 in any direction
during seismic actions or other shock forces and rolls out of its recess at a predetermined
force such that it ricochets off a housing cover covering the cradle and pushes
a trip fork mechanism having elongated walls to provide additional leverage when
the force strikes the trip fork mechanism that is mounted on a pivoting mechanism,
thereby releasing a swing arm which has a disc on the end that functions as a plug
for the hole in the valve body to interrupt gas or fluid flow therein. The improvement
comprises a novel reset valve mechanism so that a respective reset valve mechanism
is located on both sides of the valve body. In this way, regardless of how the
valve mechanism is installed, at least one reset valve mechanism will be on the
side of the valve body away from the structure wall and will be easily accessible
to reset the valve after it is tripped.
