Description
Technical field
The utility model belongs to fire-protection equipment technical field, is specifically related to fire-closing valve.
Background technique
Fire-protection valve is installed on the pipeline of ventilation, the sending of air-conditioning system, return air or mechanical smoke extraction system.At ordinary times in opening state, close when gas in pipelines temperature reaches 70 DEG C or 280 DEG C during fire, can meet within a certain period of time and leak smoke which and fire integrity demands, play the effect every cigarette back-fire relief.At present, general fire-protection valve is all by being welded after shaping operation by Q235 iron plate.During production, technique requires, except the planeness of iron plate is good after shaping operation problem, also there is the problem easily producing thermal distortion because of welding processing, thus bring very large difficulty of processing to the workman making product except existing.Existing smoke exhaust fire damper does not often reach technological requirement because of the flatness of processing rear iron plate, cause the inleakage of fire-protection valve can not be up to state standards regulation requirement.In addition existing fire-proof valve structure intensity difference, during breaking out of fire, scene of a fire high temperature can make into plane metal blade and produce distortion, occurs comparatively wide arc gap, therefore effectively can not stop spreading of flame and high temperature, can cause larger disaster.Therefore a kind of fire-closing valve is needed to solve the problems referred to above.
Model utility content
The utility model, for the deficiencies in the prior art, provides a kind of fire-closing valve.This fire-closing valve reliable performance, valve leak out less, good every cigarette back-fire relief effect.
The technical solution of the utility model is achieved in that a kind of fire-closing valve comprises with valve body and the actuator be arranged on this valve body, actuator is connected with temperature fuse, valve inner is provided with sharf, this sharf is provided with blade, described blade is connected with blade connecting rod by sharf, and actuator is connected with sharf, it is characterized in that, described blade two ends is kink shape, and centre is provided with stiffening rib; The flange with flanging is riveted at described valve body two ends respectively, is provided with the barge board matched with described blade end head shapes inside flange; Described blade two ends place is also provided with fire proof sealing strip; Described valve body, flange and blade are made up of galvanized sheet material.
Preferably, the angle of described blade two ends bending is 35 ° ~ 50 °.
Preferably, described fire proof sealing strip is made up of fire protection layer and heatproof glue-line.
Preferably, described flange is also provided with multiple boss.
Preferably, described temperature fuse is 70 DEG C of marmem temperature sensors.
The utility model solves the defect existed in background technique, has following beneficial effect:
The fire-closing valve reliable performance that the utility model provides, blade two ends is set to kink shape, also be provided with the barge board that matches with blade shape and be provided with fire proof sealing strip at blade two ends place, the face of traditional blades is contacted the contact becoming limit and limit with face, greatly reduce the inleakage of fire-protection valve, effective thus very first time smoke exhaust and air supply can be played, for the life safety of fire control and disaster rescue and people provides reliable guarantee every cigarette back-fire relief.Flange is provided with flanging and boss, and the stiffening rib on blade, improves integral rigidity, the possibility of valve body and deformable blade when reducing high temperature.This outer valve, flange and blade are made up of galvanized sheet material, and valve body and flange are riveted fixing, save tradition polishing, the subsequent technique such as zinc-plated, provide cost savings spending, improve productivity.
