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 fire protection system is provided for a space having a pitched roof constructed of structural members extending from a ridgeline to an eave, with respective channels therebetween. A first row of sprinklers is mounted to a first branch line extending generally parallel to the ridgeline. Each sprinkler is positioned within a respective channel, with consecutive sprinklers spaced apart having no less than one, and no more than five, channels therebetween. A second row of sprinklers, downslope from the first row, is mounted to a second branch line extending generally parallel to the first branch line. Each sprinkler thereof is positioned within a respective channel, with consecutive second row sprinklers spaced apart as in the first row. Each second row sprinkler is also placed within a different channel from each first row sprinkler. A farthest number of channels between a first row sprinkler and a second row sprinkler is three.

摘要： A manifold assembly is mountable to a piping manifold for a dry sprinkler system having a non-wet valve assembly separating pressurized gas on a downstream side thereof from a water supply on an upstream side thereof. The manifold assembly includes a single piece body having an inlet for removably coupling to, and receiving water from, an upstream wet standpipe, and an outlet for removably coupling to, and delivering water to, the non-wet valve assembly. A control valve assembly is mounted to the body and a mechanically independent flow detection switch is mounted to the body. Each of a test and drain valve and a pressure relief valve is fluidly connected with the body downstream of the control valve assembly and upstream of the outlet.

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： A supervisory-fluid-adjusted friction-loss coefficient based fire suppression sprinkler system has an array of pipes in fluid communication with an arrangement of sprinklers. A supervisory fluid sub-assembly is fluid communication with the array of pipes. The supervisory fluid sub-assembly provides a supervisory fluid other than air to the array. A diameter of each respective pipe of the array is determined by a friction-loss formula having a friction-loss coefficient representing a metric corresponding to a corrosion-induced internal surface roughness of each respective pipe of the array The friction-loss coefficient is determined by empirical testing of a representative pipe of the array in accordance with a nationally recognized testing procedure.

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 sprinkler system protects a combustible concealed space between a floor and a sloped roof above and includes a water supply line connected with a valve having a body and a passageway connecting an inlet and an outlet. A seal member is located and supported in a body along the passageway to block and open the passageway. A water discharge device is connected by piping with the outlet and installed in the concealed space at a location remote from the valve to spray water onto the Boon A thermal activation component includes a thermally responsive element installed at a location in the concealed space remote from the valve and the water discharge device. A flexible connector mechanically connects the thermal activation component and the valve and initiates movement of the seal member in response to a physical change in the thermally responsive element due to heating thereof.

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.

摘要： A test, drain and adjustable pressure relief module for a sprinkler system has a single body with three independent and fluidly connectable flow ports. A first port of the three flow ports is fluidly connectable at an inlet side thereof to the sprinkler system. A second port of the three flow ports has an adjustable pressure relief valve removably mounted to an outlet thereof. The valve is biased into a closed position and a threshold pressure is required to open the valve and discharge fluid is selectively adjustable. A third port of the three flow ports has an open outlet end configured to removably connect with a drainage pipe. The three ports form a Tee connection and have a flow valve therebetween to selectively direct flow between an outlet of the first port and at least one of the respective inlets of the second and third ports.
