Fig. 2 is sectional structure schematic diagram of the present utility model.
Fig. 3 is plan view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, with specific embodiment, the utility model is further described, referring to Fig. 1-Fig. 3;
The Emergeny Cutoff Valves that the present embodiment provides, comprises valve body 1, flap 2, flap axle 3, torsion spring, connecting rod 4 and pivoted arm 5.In valve body 1, be provided with flap seat 6, this flap seat 6 is for matching with flap 2, and when flap 2 is fastened on flap seat 6, its two formation is sealed and matched, and cuts off oil circuit; When flap 2 departs from flap seat 6, open oil circuit.Flap 2 is fixedly connected with flap axle 3, makes flap axle 3 and flap 2 form interlock.Flap axle 3 is installed in rotation on valve body 1, and the end of flap axle 3 is exposed at valve body 1 outside.In the present embodiment, flap axle 3 only has an end to be exposed at the outside of valve body 1.Certainly, also the two ends of flap axle all can be exposed to the outside of valve body.By torsion spring, flap 2 can be fastened on flap seat 6 flap seat and flap formation are sealed and matched, that is to say, torsion spring assembles in the mode of pre-pressing.Described pivoted arm 5 comprises arm 51 and joint 52.One end of described connecting rod 4 is connected with valve body 1, and the other end of described connecting rod 4 is connected with arm 51, and joint 52 is fixedly connected with flap axle 3; Described arm 51 is connected with joint 52 by welding manner, and this welding procedure adopts low melting material, and the fusing point of this low melting material is 75 ℃ ± 5 ℃ conventionally, 70 ℃-80 ℃.In use, when external temperature is during lower than the fusing point of low melting material, arm is formed and is rigidly connected by this low melting material and joint; Now, connecting rod and pivoted arm form tractive to flap axle, make flap depart from flap seat in flap; When external temperature is during higher than the fusing point of low melting material, described arm and joint are removed and are rigidly connected; Now, flap is subject to the elastic restoring force of torsion spring that flap is fastened on flap seat.As can be seen here, for example, when external temperature is too high when breaking out of fire (), this Emergeny Cutoff Valves can cut off oil circuit automatically, has improved safety in utilization.
