A gas fire-extinguishing apparatus according to an embodiment of the invention is configured such that a silencer is disposed on an ejection head which ejects fire-extinguishing gas supplied from a fire-extinguishing gas supply source via a conduit pipe, a diverging pipe and a branch pipe. The configuration suppresses ejection sound caused by an ejection flow of the fire-extinguishing gas.

An odor generation alarm and a method for informing an unusual situation having a high attention attracting effect and a high degree of safety are provided. An odor generation alarm includes an odorant receptacle, a drive section, a detector and a circuit section which is a controller. The odorant receptacle contains an odorant. A concentration of the odorant in air at which a person can no longer tolerate a strength of smell is lower than a no observed effect concentration of the odorant. The drive section causes the odorant to be emitted from the odorant receptacle. The detector detects occurrence of an unusual situation, and outputs a detection signal. When the detection signal from the detector is inputted, the controller causes the drive section to emit the odorant in accordance with the detection signal.

Odor generation alarm and method for informing unusual situation

One embodiment of the present invention discloses an odor-generating alarm apparatus that can ensure the reliability of a releasing operation and the odor dispersibility. In an odor-generating alarm apparatus, when abnormality information indicating occurrence of an abnormal state is supplied from a sensor for occurrence of an abnormal state, an initiator is operated by a circuit portion, and the initiator displaces a piston of a driving portion and displaces a spray can with respect to a casing and switches the spray can to a releasing state, thus releasing an odorous liquid filling the spray can in the form of fine particles.

A rapid opening pressure regulating valve reduced in size and having improved flow rate characteristics, a fire extinguishing apparatus using the same, a high-pressure gas cylinder apparatus, and an apparatus rapidly supplying a fluid. When the rapid opening pressure regulating valve is assembled, a valve element member body () is inserted into a body (), and a valve element () is inserted into an inlet nozzle part () from the inlet () thereof and fixed to the lower end of the valve element member body (). The valve element () is fixed to the valve element member body () by, for example, threading the inner circumferential surface of the valve element () and the corresponding lower end outer peripheral surface of the valve element member body () and screwing the lower end of the valve element body () into the valve element (). Since a valve seat () can be provided on the valve element (), the valve element member body () can be inserted from the upper end of the body () and the valve element () can be inserted from the inlet () of the body (), and the valve element member body () and the valve element () can be installed so as to hold the valve seat (), a conventional barrel part can be eliminated and the number of members can be reduced to reduce the size of the rapid opening pressure regulating valve.
