Abstract
The utility model relates to an indoor sprinkler with shape memory alloy for temperature sensing and driving, comprising pipe, normally open valve, spool, support and dispersion plate. It is characterized in that a short bar or spring shape memory alloy stay is equipped between inside bottoms of the spool and the support. One end of the shape memory alloy stay is positioned on the inside bottom of the support while the other end bears the spool. Because shape reset of the memory alloy stay might be adjusted and selected within a great temperature range, automatic sprinklers of different alarming levels might be designed to meet various needs. This utility model has the advantages that the memory alloy stay is with repetitive utilization, steady and reliable performance and easy access.
Description
One, technical field:
The utility model relates to a kind of indoor spray thrower, the indoor spray thrower that especially a kind of marmem temperature-sensitive drives.
Two, technical background:
The spray thrower of Gong Ying indoor fire extinguishing usefulness mostly is the glass envelope spray thrower greatly in the market, mainly is made up of water pipe, normally open valve, spool, support, glass envelope and dispersion impeller etc., and wherein glass envelope one end is placed on the support inner bottom surface, and the other end withstands spool; When this spray thrower was elevated to a certain degree in indoor temperature, the glass envelope that withstands pipeline will explosion, and spool is opened and made extinguishing chemical (normally water) ejection automatically, realized the function of sprinkling fire.This extinguishing device is simple in structure, easy for installation, but control element wherein---the fusible alloy glass tube can not use repeatedly, realize difficult adjustment of temperature of requirement action, past contact causes unnecessary loss therefrom owing to the defective of glass material causes the quick-fried or not quick-fried phenomenon of mistake.
Three, technology contents:
The purpose of this utility model is to provide and can puts out a fire according to predetermined alarm temperature, and automatic spray is stable and reliable for performance, and can use repeatedly, the spray thrower that operating temperature can be adjusted.
Technology contents of the present utility model is: the indoor spray thrower that a kind of marmem temperature-sensitive drives, comprise water pipe, normally open valve, spool, support and dispersion impeller, it is characterized by the marmem support member that a stub shape or spring shape are arranged between the inner bottom surface of spool and support, one end of marmem support member is placed on the support inner bottom surface, and the other end withstands spool.
Marmem is a kind of new functionalized material, and its obvious characteristics is through after the suitable processing and heat treatment, the shape under certain state of energy " memory " self.Universal law is: finish certain processing and heat treatment, make it obtain desired shape; After reducing temperature it is deformed, as long as this distortion is no more than certain limit (concerning niti-shaped memorial alloy, being no more than 7%), through reheating, it will be returned to original shape.
The novel advantage that is compared with prior art had of this use is;
1, support member can use repeatedly.
2, because the recovery of shape of memorial alloy can be adjusted and select, therefore just can make different other automatic spray washers of alarm temperature level as required in quite wide temperature range.
3, this uses novel stable and reliable for performancely, and is convenient to detect.
Four, description of drawings:
Fig. 1 is the utility model schematic diagram
Fig. 2 is the dispersion impeller schematic diagram
Five, utility model specific embodiment
The indoor spray thrower of marmem temperature-sensitive driving comprises water pipe 1, normally open valve 2, spool 3, support 4 and dispersion impeller 6 as shown in Figure 1.
To at room temperature with manpower this root stub shape support member 5 be aligned earlier once machining deformation and heat treated stub shape niti-shaped memorial alloy support member 5 with certain radian, pack into then in the spray thrower, stub shape support member 5 one ends are placed on the inner bottom surface of support 4, the other end withstands valve 3, play desired supporting role, guarantee automatic spray washer close and.
In a single day its operation principle is for fire alarm occurring, indoor temperature must raise, when reaching the operating temperature of stub shape niti-shaped memorial alloy support member, stub shape support member will be returned to the state of originally giving with certain radian, this moment, its vertical length can shorten, spool is opened, thereby realizes the function of sprinkling fire-distinguishing.
Stub shape niti-shaped memorial alloy support member can be changed into equally once machining deformation and heat treated spring shape niti-shaped memorial alloy support member with a less original length, at room temperature earlier spring shape niti-shaped memorial alloy support member is elongated with manpower earlier, in the spray thrower of packing into then.In case fire alarm occurs, when reaching the operating temperature of spring shape niti-shaped memorial alloy support member, spring will shorten automatically, and spool is opened, thereby realize the function of sprinkling fire-distinguishing.
