    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 fire suppression system is disclosed. The system includes a gaseous extinguishing agent and a liquid extinguishing agent. At least one emitter is in fluid communication with the liquid and gas. The emitter is used to establish a gas stream, atomize and entrain the liquid into the gas stream and discharge the resulting liquid-gas stream onto the fire. A method of operating the system is also disclosed. The method includes establishing a gas stream having first and second shock fronts using the emitter, atomizing and entraining the liquid with the gas at one of the two shock fronts to form a liquid-gas stream, and discharging the stream onto the fire. The method also includes creating a plurality of shock diamonds in the liquid-gas stream discharged from the emitter.

    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.

    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 seal for use with a knife gate valve is disclosed, the seal having a loop to which is attached an axially facing sealing lobe. A sealing surface is positioned on the sealing lobe, the sealing surface having an axially projecting leading edge and flanking annular sealing surfaces oriented angularly. Axial and inner channels extend around the loop and provide space for the loop to deform when the sealing lobe is compressed. A reinforcing band is encapsulated within the loop to stiffen it against buckling when compressed by forces acting across the leading edge. The seal is used in facing pairs with the sealing lobes being compressed against one another to form a radial seal when the valve is open. The seal is made from a flexible, resilient elastomeric compound; the band is metal.
