Description
Technical field
The present invention relates to controlling component technical field, especially relate to a kind of novel pneumatic system.
Background technique
Both at home and abroad a large amount of fire cases shows, in multilayer structure during breaking out of fire, the situation of cause smoke poisoning in personnel death's many factors, suffocating occupies the majority.Therefore, the key facility of discharging fume during as fire, the reliability that natural smoke extraction window is opened seems particularly important.Some roofs that can automatically open have been there are under fire fighting state for this reason, also having of more optimizing is positioned over roof on the track of inclination and realizes the function without electric-opening with component or the counterweight of utilizing gravity to be parallel to track, but the manual release of these roofs and automatic smoke exhausting window open many by wire rope, directly discharge or open band-type brake discharge.Due to the elastic property unbalance stress of wire rope, usually occur that part forms can not open or open incomplete situation.Meanwhile, aspect hot melt unlatching, the machinery temperature fusing point that hot melt is opened is that isolate or interrupted, and thermometric is inaccurate, also not prompt enough.That is, above-mentioned technology also has certain potential safety hazard in the application of fire-fighting domain.
Summary of the invention
The object of this invention is to provide a kind of novel pneumatic system, it has can make natural smoke extraction window open in time, effectively, reliably, and more adapts to complicated personalized fabric structure and the feature of inside decoration.
The technical solution adopted in the present invention is: novel pneumatic system, and described novel pneumatic system comprises:
---cylinder, the upper and lower of this cylinder has respectively the first suction port and the second suction port, and this cylinder has piston rod;
---fiery inserting tube, this fire inserting tube is plastics fire inserting tube or metal fire inserting tube, when it adopts non-low melting alloy to belong to the metal fire inserting tube that pipe is prepared from, on its tube wall, be distributed with blast hole, and this blast hole gives shutoff by low melting alloy or the tinsel that welds by low melting alloy gives shutoff;
---the first tracheae, the second tracheae, this first, second tracheae is a kind of in metal tube, heat resistant plastice pipe, rubber pipe;
---the first valve, the second valve, the 3rd valve, the 4th valve;
---threeway, this threeway has first interface, the second interface, the 3rd interface;
---gas tank; And
The upper end of this fire inserting tube is communicated to this first suction port, and the upper end of this first tracheae is communicated to this second suction port;
The lower end of this fire inserting tube is communicated to this second interface by the 3rd valve, and the lower end of this first tracheae is communicated to this first interface by this first valve;
One end of this first valve is communicated with this first tracheae, the other end is open, and one end of the 4th valve is communicated with this fire inserting tube, the other end is open;
The 3rd interface is communicated to this gas tank.
Described cylinder replaces with pneumatic motor.
The advantage that the present invention has is: can make natural smoke extraction window open in time, effectively, reliably, and more adapt to complicated personalized fabric structure and inside decoration.Novel pneumatic system of the present invention substitutes wire rope to control the unlatching of pneumatic window with the stretching of piston rod of cylinder, efficiently solve the problem of wire rope gearing unbalance stress, simultaneously, the fiery inserting tube adopting is comparatively sensitive to heat energy, point for measuring temperature is also relatively continuous, solved original technology hot melt open imperfection, not in time, inaccurate problem, thereby solve natural smoke extraction window and can not open in time, effectively, reliably problem, make the closed position of natural smoke extraction window more accurate, and opening speed is controlled.And, owing to adopting gas circuit transmission power, at corner and when wiring, no longer as wire rope form, need numerous pulleys turn to and lead, and pulley fixed bearing firmly, therefore interior of building is decorated to the little while of impact and more adapt to complicated personalized construction steel structure.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described:
