    摘要： An example internal relief valve disclosed herein includes a relief valve seat coupled to a first end of the relief valve stem and to engage a first side of a sensing apparatus to prevent fluid flow between the first side of the sensing apparatus and a second side of the sensing apparatus when the internal relief valve is in a closed position. A bleed hole within a surface of the sensing apparatus and separate from the opening of the sensing apparatus is dimensioned to provide a controlled flow rate between the first side and the second side of the sensing apparatus when the internal relief valve is in an open position. A seal is disposed along a body of the relief valve stem upstream from the bleed hole and the valve seat to prevent fluid flow between the first side of the sensing apparatus and the second side of the sensing apparatus via the opening of the sensing apparatus when the relief valve is in the open position.

    摘要： A slam-shut safety device includes a valve body, a valve disc, a reset pin, a and a guide collar. The valve disc is shiftable between an open position spaced away from a valve seat, and a closed position seated against the valve seat. The reset pin operatively is coupled to the valve disc and shiftable between an untripped position placing the valve disc in the open position and a tripped position placing the valve disc in the closed position. The guide collar includes a hollow cylindrical portion slidably supported in a guide bore and extending at least partly over the reset pin at a location adjacent to the valve disc. The guide collar is shiftable between a retracted position and an extended position relative to the guide bore for providing added structural integrity and protecting the reset pin from bending forces.

    摘要： A slam-shut safety device includes a valve body, a valve disc, a reset pin, and a guide collar. The valve disc is disposed within the valve body and shiftable along a slam-shut axis between an open position and a closed second position. The reset pin is operatively coupled to the valve disc and shiftable along the slam-shut axis relative to the valve body between an untripped position placing the valve disc in the open position and a tripped position placing the valve disc in the closed position. The guide collar includes a hollow cylindrical portion extending away from the valve disc at least partly over the reset pin and being slidably disposed in a guide bore of a slam shut body that is connected to the valve body and supporting the reset pin, thereby providing added structural integrity to the rest pin and valve disc.
