Problems solved by technology
However, many fire extinguishing devices used in the prior art can only protect one protection area or a piece of equipment, and do not use a suitable fire detection tube temperature-sensitive self-starting fire extinguishing device selection valve to realize simultaneous protection of several protection areas or multiple units. The protection of equipment leads to the repeated configuration of fire extinguishing devices and the waste of fire extinguishing agents, and the excess fire extinguishing agents can easily cause environmental pollution

The invention discloses a selection valve of a fire detecting tube temperature sensing self-starting fire extinguishing apparatus. The selection valve mainly comprises a screw sleeve, a valve body, a piston, a piston compression spring, a fire detecting tube valve clack sleeve, a fire detecting tube valve clack sleeve compression spring and a screw plug and is characterized in that the screw sleeve is in screw joint with the valve body. The piston and the piston compression spring are arranged in the valve body, and the fire detecting tube valve clack sleeve, the fire detecting tube valve clack sleeve compression spring and the screw plug are arranged in the piston. The selection valve of the fire detecting tube temperature sensing self-starting fire extinguishing apparatus plays a role in controlling the flowing direction of a fire extinguishing agent and releasing the fire extinguishing agent and is mainly applied to a combined distribution fire extinguishing system for protecting few protection areas at the same time; and when a fire disaster of a certain protection area happens, the selection valve of the protection area is started to spray the fire extinguishing agent to implement fire extinguishing.
Description
Technical field [0001] The present invention relates to a selection valve, in particular to a selection valve of a fire detection tube temperature sensing self-starting fire extinguishing device, which is installed on the fire detection tube temperature sensing self-starting fire extinguishing device and used to control the flow direction of the fire extinguishing agent and release the fire extinguishing agent. Kind of valve. Background technique [0002] At present, the installation of fire detection tube temperature-sensing self-starting fire extinguishing devices in equipment and facilities such as power distribution rooms, electrical cabinets, and mobile communication base stations has attracted much attention. However, many fire extinguishing devices used in the prior art can only protect one protection area or one piece of equipment, and no suitable fire detection tube temperature sensing self-starting fire extinguishing device selection valve is used to realize simultaneou...
