摘要： A valve has a valve body that defines a chamber. The chamber has an inlet and an outlet through which a flow path passes. A seat is positioned within the chamber and surrounds the flow path. A closing member is positioned within the chamber and a biasing member biases the closing member into an open position away from the seat. The biasing member exerts a biasing force on the closing member which exceeds the force exerted on the closing member by a first fluid which enters the inlet and flows past the closing member and through the open valve. The biasing force is less than the force exerted by a second fluid having one or more different characteristics from the first fluid. Force exerted by the second fluid on the closing member overcomes the biasing force and moves the closing member into engagement with the seat, closing the valve.

摘要： An actuator for use with a negative pressure fire suppression sprinkler system is disclosed. The actuator has three chambers, each chamber having a flexible diaphragm. One chamber is connected to the sprinkler system piping network. Its diaphragm moves in response to an increase in pressure in the piping network signaling a fire. The diaphragm in the second chamber opens an orifice in response to the motion of the first diaphragm. The open orifice allows water to flow from the third chamber to the ambient. The diaphragm in the third chamber moves in response to the water flow from the third chamber. The third chamber is connected to a valve controlling water flow to the piping network. Motion of the diaphragm in the third chamber actuates the valve, releasing water to the system.

摘要： A valve for fire suppression sprinkler systems is disclosed. The valve has a chamber with an inlet and an outlet. A closure member, positioned within the chamber, is movable to close and open the inlet. A latch engages the closure member to hold it in the closed position. The latch also engages a deformable diaphragm. The diaphragm deforms in response to pressure applied to it and allows the latch to move between a latched position engaged with the closure member and an unlatched position away from the closure member. When the diaphragm is depressurized it allows the latch to move and disengage from the closure member, which opens under fluid pressure from the inlet and allows fluid to flow through the valve.

摘要： A fire suppression sprinkler system convertible between a wet and a dry mode of operation is disclosed. The system features a field convertible valve having a bypass loop with a bypass valve for selectively configuring the valve for wet or dry mode operation. For dry mode operation, the bypass valve is open. The field convertible valve also has a system actuator, a gas control valve and a water supply shut-off valve which are open in the dry mode. In the wet mode of operation, the bypass valve is open and the gas control and water supply shut-off valves are closed. The field convertible valve operates in a latch mode controlled by the system actuator in the dry mode, and as a flapper valve in the wet mode of operation. A method of converting the mode of operation of the sprinkler system is also disclosed.

摘要： A sprinkler system and a method for mitigating scaling, microbiological influenced corrosion and oxidative corrosion are disclosed. The system includes a piping network in fluid communication with a source of pressurized water and an air pump. The network is vented to the ambient. The air pump moves initially dry ambient air through the system, either by maintaining a negative or a positive air pressure within the network. The dry air absorbs residual water within the network and exhausts it to the ambient. Rate of air flow through the system is controlled by restrictor elements such as orifices, throttle valves or venturies within the piping network.

摘要： Apparatus and method for converting a fire suppression system from a single interlock electric or double interlock electro-pneumatic system to a single interlock pneumatic system which draws no electrical power. A pneumatic actuator is in fluid communication with a pressurized piping network and a control valve controlling flow of fire suppressant to the network. The pneumatic actuator is isolated from the piping network by a check valve and a latching solenoid valve. In the event of a power failure the latching solenoid valve is opened, placing the pneumatic actuator in fluid communication with the piping network. Electrical power is drawn only to change the state of the latching solenoid valve, it otherwise draws no power. When the latching solenoid valve is open the pneumatic actuator controls actuation of the control valve, and triggers the control valve when there is a pressure change in the piping network indicative of a fire.
