Description
Technical field
The utility model relates to the SE field, specifically is that a kind of fire and smoke exhaust valve is used temperature sensor.
Background technique
At present, high-rise all is equipped with ventilation duct, and the fire and smoke exhaust valve in the ventilation duct requires to possess temperature sense and control function, and above-mentioned functions relies on and on the fire and smoke exhaust valve temperature sensor is set and realizes.Temperature control element in the temperature sensor of existing technology is to adopt acolite and metalwork to be welded; After arriving assigned temperature; The acolite dissolving causes temperature control element to be broken off, and temperature control element is broken off actuator's running that can touch the fire and smoke exhaust valve, finally realizes the unlatching of valve.Because the temperature control element of existing technology just can't be reused after breaking off, promptly temperature control element is disposable temperature control element, so only uses once the back just must change temperature control element, so inconvenience and maintenance cost are high.
Summary of the invention
The technical problem that the utility model will solve is to provide a kind of fire and smoke exhaust valve that can use repeatedly to use temperature sensor.
The technical solution of the utility model is, provides a kind of fire and smoke exhaust valve to use temperature sensor, and it comprises a sleeve and a main shaft; Two end plates of sleeve all are penetrated with through hole; Two through holes of two end plates of sleeve are passed at the two ends of main shaft respectively, and an end of main shaft is provided with first limiting stopper, and this end of main shaft also is sheathed with memory alloy spring; Memory alloy spring is between an end plate of first limiting stopper and sleeve; The other end of main shaft is fixed with second limiting stopper, and the shaft part that main shaft is positioned at sleeve is provided with confined planes, is provided with stage clip between the end plate near first limiting stopper of confined planes and sleeve.
The fire and smoke exhaust valve that adopts above structure with temperature sensor compared with prior art has the following advantages:
The working principle of this temperature sensor is: when the temperature of present position meets or exceeds the assigned temperature of memory alloy spring; Memory alloy spring will elongation strain; And sleeve is fixed; The memory alloy spring of elongation will promote first limiting stopper to away from the motion of the direction of sleeve, so drive main shaft final drive be fixed on the main shaft the other end second limiting stopper to direction motion near sleeve, second limiting stopper moves; Will touch actuator's running of fire and smoke exhaust valve, finally realize the unlatching of valve; After dropping to the assigned temperature that is lower than memory alloy spring when temperature; Memory alloy spring returns to original shape and length again; Compressed stage clip is passed the confined planes of main shaft to the direction away from first limiting stopper, and then drives second limiting stopper that is fixed on the main shaft away from sleeve and finally get back to initial position, like this; When meeting with high temperature, this temperature sensor still can reuse next time.
In sum, this fire and smoke exhaust valve can repeated multiple times uses with temperature sensor, use and all need not the temperature control element that more renews behind the one or many, so make things convenient for and the working service cost low.
As improvement, sleeve is made up of first nut, sleeve pipe and guide sleeve, and the external thread rotary of guide sleeve is combined in the female end of sleeve pipe, and the internal thread of first nut screws the male end at sleeve pipe, such structure, and the manufacturing assembling is all simple and convenient.
As also improving; Main shaft is made up of mandrel and pull bar, and mandrel is provided with blind screw hole, and an end of pull bar is provided with outside thread; One end of pull bar screws in the blind screw hole of mandrel; The step surface of mandrel and pull bar joint constitutes confined planes, like this, can assemble the main shaft that produces the band confined planes easily.
As improving, the end away from mandrel of pull bar also is provided with outside thread again, and this end of pull bar is combined with second nut, and like this, second nut has just formed first limiting stopper that is fixed on the main shaft, and this is simple in structure and easy to assembly.
