Description
Technical field
The utility model belongs to fire resisting damper technical field, and in particular to a kind of novel fire damper.
Background technique
Known, fire resisting damper is a kind of open type valve, leads to direct current 24V by control centre and is electrically turn off or is turned off manually, 70
DEG C when fusing close, reset must manually.Its effect is: when flue-gas temperature reaches 70 DEG C, evacuation finishes people substantially, arranges
Cigarette is without practical significance, and band fire, valve fusing at this time is closed in flue gas, to avoid fire spreading to other regions.
Existing fire resisting damper is mostly welded by steel plate and components, is polished after welding by solder joint, derusting,
Oil removing, spray painting, assembling have that speed is slow, noise is big, has floating dust and produces until complete the production in production manufacturing process
The process of the environmental pollutions such as raw dangerous waste, solid waste, and the drawback that finished product has appearance bad after polishing.
For the drawback in the prior art, how by technological improvement, by existing valve body, blade construction, in conjunction with existing
There is accessory, realize the riveted structure between each components, generates maximum discharge, highly energy-consuming, dirt to avoid welding, polishing, spray painting etc.
The work step of metachromia is existing industry technical staff technical problem urgently to be resolved, caters to the energy conservation that country advocates at present and subtracts
Row, environmentally protective policy.
Utility model content
To realize that above-mentioned technical functionality, the technical solution of the utility model are as follows: a kind of novel fire damper, material therefor are
Galvanized steel plain sheet a comprising valve body, the valve body are continuous roll forming, and the riveting of only one interface combines, and valve body
An ancient unit of weight has strengthening groove to improve the resistance to fire intensity of fire resisting damper entirety on left and right frame, and the inner vertical of valve body is fixed with more blades
And riveting has stiffening plate, all blades are by axis fixing plate and axis connection, wherein the drive shaft is connected with executing agency, institute
The blade on the blade and drive shaft on driven shaft stated is fixedly connected by the link assembly at intermediate position, by executing agency's band
Dynamic drive shaft movement is to drive all blade linkages (closing or opening)；It is respectively coated on the copper sheathing frame of valve body upper and lower
For the stainless steel elastic slice of one arcuation for closed with blade, stainless steel elastic slice can be with the variation of angle when blade opens or closes
And change, to play the role of closed.In adjacent two panels blade junction, the end of blade all using it is flat take combination by the way of,
On the blade on right side, with lobus lateralis sinister oblique cut grafting at have stainless steel blade elastic slice, be to be withheld by a V-type pressing plate,
Blade elastic slice is pressed on blade and is riveted fixation, blade elastic slice and left side blade, which are put down, to be taken.
The blade and valve body left and right sidewall baffle of the valve body left and right ends also take mode using flat, by valve buckle body
The left and right sides rivets baffle on strengthening groove middle position, and increases stainless steel elastic slice between baffle and valve body, and bending angle compares baffle
Angle is slightly larger and overlaps with blade.
The utility model has the beneficial effects that the utility model by designing above, effectively increases the strong of valve body and blade
Degree, material are changed to be changed to rivet by the mode of original welding without the galvanized steel plain sheet of spray painting, be fixed on blade by riveting axis
The mode of plate fixes blade and driven shaft and drive shaft, uses chain assemblies horizontal connection to realize blade using between blade
Between linkage；Furthermore the utility model is by riveting blade elastic slice in each blade lap-joint, and in blade in conjunction with valve body
The mode for increasing stainless steel elastic slice at baffle realizes between blade that no-welding-spot is flat and takes closed combination, both ensure that leakproofness between blade,
Welding, polishing operation are in turn avoided simultaneously, reduce noise, drift along etc. and is generated without dangerous waste, solid waste, moreover it is possible to improve production effect
Rate is a kind of ideal novel fire damper.

Specific embodiment
The utility model is further described through with reference to the accompanying drawing.As shown in the picture, a kind of novel fire damper, it is former
Material is galvanized steel plain sheet comprising a valve body 1, valve body 1 are continuous rolling molding, and the riveting of only one interface combines, valve body
The left and right sides have a strengthening groove, the inner vertical of valve body 1 is fixed with more blades 7, and riveting has blade stiffening plate 2 on blade 7,
In drive shaft 4, being connected by riveting blade axis fixing plate 5 and blade 7, the drive shaft 4 and executing agency 3 connect,
The both ends of remaining blade 7 also by blade axis fixing plate 5 respectively with driven shaft 6 connect, all blades 7 middle position with
8 horizontal connection of chain assemblies is linked between realization blade by being connected with upper member；As shown in figure 5, driven shaft 6 and drive shaft 4
A copper sheathing 10 is coated at the uniformly distributed hole position for passing through copper sheathing frame 12, the top of the copper sheathing frame 12, arcuation
Stainless steel elastic slice 11 will coat above copper sheathing frame 12.
Further, as shown in fig. 6, in adjacent 7 junction of two panels blade, combination is all taken using flat in the end of blade
Mode, on the blade 7 on right side, with lobus lateralis sinister oblique cut grafting at pass through one 13 He of blade elastic slice of riveting machine two ply riveting
One V-type pressing plate 14, as shown in riveting point 15 in Fig. 6, the V-type pressing plate 14 detains blade elastic slice 13, blade elastic slice 13
It puts down and takes with left side blade, blade elastic slice 13 will be tightly attached on the blade 7 of left side by wind pressure in pipeline after blade 7 is closed, will
It is sealed between adjacent blades.
Further, the 1 left and right sidewall baffle 9 of blade 7 and valve body of the left and right sides edge also takes mode using flat,
Reinforce baffle 9 by riveting L-type in 1 left and right sidewall of valve body, and increases as baffle shape between baffle 9 not in side wall
Become rusty steel bomb piece 16.
The utility model by designing above, and by the mode of original welding all using riveting, such processing method is by valve
Body raw material are directly changed to galvanized sheet and stainless steel plate accessory, do not have be ugly in appearance caused by subsequent welding, destroy zinc layers,
The drawbacks such as polishing, touch-up paint, the utility model is on blade 7 by blade 7 and driven shaft by way of riveting blade axis fixing plate 5
6 and drive shaft 4 it is fixed, and the resistance to fire intensity of entirety for having blade stiffening plate 2 to improve blade 7 is riveted on blade 7, then use
All blade horizontal connections are realized interlobate linkage by chain assemblies 8, furthermore, the utility model passes through the lap-joint between blade
By the way of riveting blade elastic slice 13, and in blade 7 and 1 junction of valve body, riveted on valve body 1 L-type reinforce baffle 9 and
The mode of baffle elastic slice 16 realizes that 7 no-welding-spots of each blade are flat and takes closed combination, has both improved body strength and has in turn ensured blade
Between leakproofness, while welding, polishing operation are in turn avoided, in conclusion blade and blade, blade and baffle, blade and copper
There is the sealing of stainless steel elastic slice in stock overlap joint contact site, substantially increases the airtightness after valve blade is closed, and on a left side
Roll-in strengthening groove and rivet that blade stiffening plate is reinforced and L-type reinforces the modes such as baffle to improve fire prevention on sharf on left frame
The integral strength of valve is a kind of ideal novel fire damper.
