摘要： Multidirectional vent limiting devices for use with fluid regulators are described. An example vent limiting device includes a housing having an interior surface, a fluid inlet, a fluid outlet, and a first fluid passageway in fluid communication with and located between the fluid inlet and the fluid outlet. The interior surface includes a first sealing surface that defines a portion of the first fluid passageway. The vent limiting device further includes a stem having a first end, a second end located opposite the first end, and an axial portion located between the first end and the second end. The vent limiting device further includes a poppet having a first end, a second end located opposite the first end, a second sealing surface that defines a portion of the first fluid passageway, and a bore that defines a second fluid passageway in fluid communication with and located between the fluid inlet and the fluid outlet. The first end of the stem is rigidly coupled to the poppet. The poppet is slidable in an axial direction within the housing between an open position and a closed position. The second sealing surface contacts the first sealing surface when the poppet is in the closed position to close off the first fluid passageway.

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： Multidirectional vent limiting devices for use with fluid regulators are described. In some examples, a vent limiting device includes a housing having an interior surface, a fluid inlet, a fluid outlet, and a first fluid passageway in fluid communication with and located between the fluid inlet and the fluid outlet. The interior surface includes a first sealing surface that defines a portion of the first fluid passageway. In some examples, the vent limiting device further includes a stem and a poppet. In some examples, the stem is rigidly coupled to the interior surface of the housing. In some examples, the poppet includes a second sealing surface that defines a portion of the first fluid passageway, and a radial bore that defines a second fluid passageway in fluid communication with and located between the fluid inlet and the fluid outlet. In some examples, the poppet is slidable along the stem between an open position and a closed position. In some examples, the second sealing surface contacts the first sealing surface when the poppet is in the closed position to close off the first fluid passageway.

摘要： A fluid regulating device includes a valve body having an inlet, an outlet, and a valve port, a control element adapted to be displaced relative to the valve port to control the flow of a fluid between the inlet and the outlet, a control assembly operatively coupled to the control element and including a diaphragm disposed adjacent a diaphragm chamber, and a sense tube. The sense tube has a first end, a second end, and a sense hole formed adjacent the second end. The first end is positioned to communicate with the diaphragm chamber, and the second end is disposed adjacent the outlet, with the second end being movable, relative to the first end, between a first position within the valve body and a second position extending outside of the valve body, the movement being in response to fluid flowing between the inlet and the outlet.
