    摘要: A thermal trigger assembly for remote mechanical actuation of another fire protection system component includes an activation component having a base and a movable member. A bias member biases the movable member from a preactivation to an activated position with respect to the base. A thermally responsive element retains the movable member in the preactivation position until a predetermined thermodynamic condition is reached, when the thermally responsive element loses structural integrity. A flexible connector includes a flexible hollow outer cable housing with one end configured to be stationarily (preferably fixedly) connected with the base. A flexible cable is inside the outer cable housing for sliding movement therein and has one end configured to be stationarily (preferably fixedly) connected with the movable member. The flexible cable is moved with respect to the outer cable housing by movement of the movable member upon loss of structural integrity by the thermally responsive element.

    摘要: A wet piping system modular valve assembly includes a single piece valve body with a check valve within the valve body. The check valve is movable between a closed position and an open position according to a pressure differential across the check valve. A drain valve is removably mounted to the valve body and fluidly connected with the valve body downstream of the check valve. A mechanically independent flow detection switch is removably mounted to the valve body and fluidly connected with the valve body upstream of the drain valve.

    摘要: A fire-protection system for delivering a fire-control fluid includes a valve having a body with an inlet, an outlet, and a fluid passageway connecting the inlet with the outlet. A seal member is supportable across the passageway to close the passageway. The seal member is supported across the passageway in a sealing position in a pre-activation condition of the valve. The seal member is movable from the sealing position to a fluid-flow position in an activated condition of the valve. The seal member includes a support body having a longitudinal axis, a seat, a leading surface facing in an upstream direction from the seat, and a trailing surface located in a downstream direction from the seat and contoured radially inwardly in the downstream direction. A Belleville washer is mounted on the seat of the support body.

    摘要: An adjustable drop nipple has an upper pipe with an inlet end adapted for connection to a branch pipe, and an outlet end. A lower pipe is telescopically and sealingly engaged with the upper pipe and has an inlet and an outlet including a connection for a sprinkler head. Upper and lower supports are respectively fixed to the upper and lower pipes. A vertical support member is positioned generally parallel to the longitudinal axes of the upper and lower pipes and is secured to the upper and lower supports by upper and lower fasteners, respectively. The upper fastener permits the vertical support member to travel axially upwardly upon an application of a primarily upward axial force, but prevents the vertical support member from traveling axially downwardly upon the application of a primarily downward axial force.

    摘要: A combination control and check valve assembly for a wet piping system includes a control valve in the form of a ball valve and a one-way check valve mounted within the flow pathway of the ball valve. A valve actuation assembly is mounted to the valve assembly to selectively rotate the ball valve between the open and closed positions thereof. The valve actuation assembly is mounted to a first side of the valve assembly and rotationally fixed to the ball, whereby rotation of the valve actuation assembly rotates the ball between the open and closed positions. A side opening is formed in a second side of the valve assembly that is angularly spaced from the first side. The side opening is positioned to align with the fluid flow pathway of the ball valve in the closed position thereof to provide access to the check valve.

    摘要: A thermal trigger assembly for remote mechanical actuation of another fire protection system component includes an activation component with a distal base, a distal movable member, a proximal base, a proximal movable member, and a bias member biasing the proximal movable member from a preactivation position to an activated position located proximally of the preactivation position. A thermally responsive element is retained by the distal base, loses structural integrity under occurrence of a predetermined thermodynamic condition, and thereby allows the distal movable member to move from a preactivation position to an activated position with respect to the distal base. A flexible connector connects the proximal movable member to the distal movable member. Upon the loss of structural integrity by the thermally responsive element, a biasing force from the bias member causes a movement of the proximal movable member from the preactivation position to the activated position.
