Memory alloy valve for building fire extinguishing system

Abstract

The invention relates to a memory alloy valve for a building fire extinguishing system. The memory alloy valve comprises a floor slab and further comprises a runner pipe, the runner pipe comprises a first water spraying pipe with one end rotatably arranged on the floor slab and a second water spraying pipe with one end rotatably arranged on the other end of the first water spraying pipe. According to the memory alloy valve, a traditional fire extinguishing mode is improved, two temperature sensing mechanisms in a temperature sensing device are used for sensing the indoor temperature, the first water spraying pipe can rotate to drive a control part to rotate and open a closing part, a first blocking plate is driven by a lifting mechanism to open a first circulation hole, a flow channel in the second water spraying pipe can be opened, water flow passes through an atomizing spray head for fire extinguishment, atomized water in atomizing fire extinguishment is small in particle, large in coverage and high in cooling performance, a very good rapid fire extinguishment effect can be achieved on a small-range fire disaster, the equipment cannot be damaged even if the atomized water sinks on the electrical equipment, and good fire extinguishing and equipment protecting effects are achieved.

Description

technical field [0001] The invention relates to the technical field of fire-fighting valves, in particular to a memory alloy valve for a building fire-fighting system. Background technique [0002] The valve is a pipeline accessory used to open and close the pipeline, control the flow direction, adjust and control the parameters of the conveying medium, and there are many applications of the valve in fire protection, such as the opening mode of the open sprinkler head and the closed sprinkler head , the open nozzle is always in the normally open state, the nozzle can spray water directly, generally opened by the electric deluge valve, and the closed nozzle is normally closed under normal conditions, when the temperature reaches the set threshold, the temperature sensing element falls off open. [0003] At present, areas such as office buildings are usually equipped with the above two types of fire extinguishing equipment. When a fire occurs, it can be automatically turned o...

Problems solved by technology

[0003] At present, areas such as office buildings are usually equipped with the above two types of fire extinguishing equipment. When a fire occurs, it can be automatically turned on to put out the fire. Water spray is usually sprinkled on the fire in the form of droplets. Although it has the effect of extinguishing the fire, the electronic equipment is also damaged or even completely damaged due to the falling of the water droplets, and the resulting data loss is irreparable. Play a very good fire extinguishing effect and the effect of protecting equipment
