Abstract: A main valve for a straightway deluge valve includes a valve body (1), a valve cover (2), a diaphragm (3), a drawing piston (4), a diaphragm pressure plate (5), a drawing link (6), a valve body link (7), a valve plate link (8), a rotatable lip and a mounting hole cover (13). A piston guide is provided at a side part of the valve body (1). The drawing piston (4) is provided slidably in the piston guide along a left-right direction. When the drawing piston (4) slides along the piston guide, the rotatable lip can contact with or separate from the inner sealing end surface. The main valve for drawing the straightway deluge valve, after the valve plate (9) is opened, enables the flow passage to be close to a straightway passage, thereby reducing flow loss.

Abstract: The present invention relates generally to the technical field of smart home. More particularly, it relates to a sweeping and fire extinguishing device comprising a sweeping robot, a fire extinguishing mechanism and a body frame, wherein said fire extinguishing mechanism is disposed in a space surrounded by the body frame while said sweeping robot is disposed under the fire extinguishing mechanism. Said sweeping robot comprises a body, a processer, an abutting hole and a camera, wherein an abutting terminal is disposed in said abutting hole. Said camera and the abutting terminal are both electrically connected to the processor; Said fire extinguishing mechanism comprises a supporting platform and a clamping mechanism, wherein said supporting platform comprises an abutting block on its lower end and said abutting block comprises a connecting terminal. Said supporting platform comprises a swinging mechanism for placing a fire extinguisher.

Abstract: A dry pilot actuator provides for a high liquid to gas trip ratio. The actuator includes a housing having an interior surface defining an internal chamber with a central axis. The valve further includes a first inlet port; a second pilot port and a third drain port, each in communication with the internal chamber. A first actuator seat is disposed along the interior surface of the housing circumscribed about the central axis and a second actuator seat is circumscribed about the first actuator seat. A seal member having a sealed position and an open position is substantially aligned with the central axis of the housing in each of the sealed and open positions. The third port is isolated from the first and second port when the sealing member is in the sealed position, and in fluid communication with the first port when the sealing member is in the open position. The second port is isolated from the first and third ports when the sealing member is in the actuated position.

Abstract: A sprinkler assembly includes a body, a support, which extends from the body, and a closure device that releasably closes the discharge opening of the body. The sprinkler assembly further includes a trigger that releasably holds the closure device at the discharge opening. The support is adapted to allow the fluid flowing from the discharge opening, when the closure device is released, to pass through the support substantially unimpeded by the support and, further, is adapted to reshape the flow of fluid as it flows through the support.

Abstract: An improved fire protection system that is of fail safe design for kitchen stoves with or without a range hood and other applications utilizing electrical power for generating heat and in which a fire condition such as a skillet of grease becomes ignited. Said system is activated thermally to release a quantity of fire suppressant material while simultaneously cutting off the electrical power. The system utilizes a reservoir containing the fire suppressant under pressure with a hose or pipe connected to one or a plurality of thermally activated nozzles. A second hose or pipe is connected to a pneumatically operated electrical interruption device.

Abstract: Provided is a fire-fighting robot that can quickly start to fight a fire occurring at a hazardous location, which firefighters cannot access, and extinguish fires occurring at any location without receiving a supply of fire extinguishing water. The fire-fighting robot (1) of the present invention is self-propelled and remote-controlled via wireless or mobile communications to fight a fire. The robot includes one or more fire extinguisher storage portions (24a, 24b) for storing fire extinguishers (24c, 24d) which provide a jet of a fire-fighting agent from a jet outlet (26) by depressing a lever, a jet control portion disposed in the fire extinguisher storage portion (24a, 24b) for depressing the lever, and a jet outlet securing portion (26a) for detachably securing the jet outlet (26) of the fire extinguisher (24c, 24d).

Abstract: A booster actuator 10 may be positioned between the solenoid 12 and a valve 14, and increases the energy output from the solenoid to activate the valve. The booster actuator 10 may include a force input member 28 and a force output member 30 each linearly movable with respect to a body 20 from an initial position to an activated position. A coil spring 46 biases the input member to the initial input position, while a plurality of disk springs 48 bias the output member 30 to the activated output position. A plurality of linking members 32 each pivotable with respect to the body normally retain the force output member in the initial position, but upon movement of the input member to the activated position release the force output member in response to the disk springs.

Abstract: A modular valve field convertible between a wet and dry configuration including a valve body and a passage within the valve body for allowing fluid to flow therethrough. A valve seat and clapper are positioned within the valve body. The clapper is allowed to pivot between a first position wherein the clapper is sealingly engaged with the valve seat and a second position wherein the clapper is spaced from the valve seat to allow fluid to flow through the valve. The operator controls the position of the clapper with respect to the valve seat. An operator securely retains the clapper in the first position in a first mode of operation and allows the clapper to freely move between the first and second positions in a second mode of operation. A controller governs the position of the clapper with respect to the valve seat when the operator is in the second mode of operation.
