Background technique
The volume damper (hereinafter referred to as air-valve) that Dimensions is larger, particularly be used in and have certain requirements in ventilation system to air-valve intensity, general employing split production, but the air-valve of this split production often causes transmission effect undesirable because blade transmission mechanism is complicated.Current air-valve manufacturing firm normally increases dividing plate between linear leaf air-valve framework, is divided into the framework that 2-3 is used for installing short blade, to strengthen the intensity of framework and blade; But current dividing plate adopts rectangular steel pipe Type of Welding to make mostly, also exist dividing plate difficulty of processing large, to weld with valve body rear blade assemble difficult, weld that subsequent treatment is loaded down with trivial details, blade and the problem such as spacer gap is large.
Model utility content
For the problems referred to above, the utility model provides a kind of air-valve dividing plate, has simple, the easy to assembly and intensity advantages of higher of preparation process.
For achieving the above object, the technical solution of the utility model is as follows: air-valve dividing plate, comprising: C-type steel, flat board, spacer sleeve, L-type part and axle sleeve; Described C-type steel is folded by steel plate and forms, and the first portion of C-type steel with several equally spaced hole flangings I, and is respectively equipped with the circular hole for installing L-type part on both sides; Described flat board, with the hole flanging II corresponding with C-type steel, lower edges is provided with equally spaced staking nail; Described L-type part, make of Equal Angle Steel, two planes are all threaded hole, are used for respectively being undertaken fastening with C-type steel and air-valve framework by bolt; Described spacer sleeve, is made up of steel pipe Vehicle Processing, and internal diameter is greater than hole flanging I and hole flanging II outside dimension; The opening surface of C-type steel is provided with the pulling rivet bottom outlet matched with staking nail, by pulling rivet by C-type steel and the fastening assembling of flat board, inlay axle sleeve in hole flanging I and hole flanging II, its outside is provided with spacer sleeve, and L-type part is placed in the C-type steel and dull and stereotyped two ends that assemble;
Described staking nail is placed in the midline position of adjoining hole flanging II;
Described end face of shaft bush slightly exceeds the first portion of C-type steel and dull and stereotyped plane;
The thickness of described C-type steel is 1.5mm or 2mm;
Described flat board is identical with material with C-type steel thickness;
The beneficial effects of the utility model are: this kind of air-valve dividing plate component make simple, easy to assembly, vane end faces and septum plane gap is little, intensity is high, be convenient to fixing and dismantling of dividing plate and valve body, can be used in the various material air-valves such as carbon steel board, corrosion resistant plate, galvanized sheet and aluminising plate, the air-valve obturation effect applying this dividing plate is fabulous;
Staking nail is placed in the midline position of adjoining hole flanging II, and the pulling rivet avoiding vane end faces and protrusion is interfered; Spacer sleeve can ensure that C-type steel is consistent with the rectangle plane of dull and stereotyped composition; End face of shaft bush slightly exceeds the first portion of C-type steel and dull and stereotyped plane, this ensure that vane end faces and septum plane gap not too large and cause leakage rate to exceed standard.

Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1
Dividing plate material is consistent with air-valve material.
Air-valve dividing plate, comprising: C-type steel 5, flat board 2, spacer sleeve 3, L-type part 8 and axle sleeve 1; Described C-type steel 5 is folded by the steel plate that 1.5mm or 2.0mm is thick and forms, and the first portion 10 of C-type steel with several equally spaced hole flangings I 11, and is respectively equipped with the circular hole 9 for installing L-type part 8 on both sides; Described flat board 2 and the material of C-type steel 5 and consistency of thickness, with the hole flanging II 12 corresponding with C-type steel 5, lower edges is provided with equally spaced staking nail 4, except 4 the staking nail 4 being positioned at two ends, all the other staking nail 4 are positioned at the midline position of two contiguous hole flangings II 12, and the pulling rivet of vane end faces and protrusion can be avoided like this to interfere; Described L-type part 8, make of Equal Angle Steel, two planes, all with two tapped holes, are used for being undertaken fastening with C-type steel 5 and air-valve framework by bolt respectively; Described spacer sleeve 3, is made up of steel pipe Vehicle Processing, and internal diameter is greater than hole flanging I 11 and hole flanging II 12 outside dimension; The opening surface of C-type steel 5 is provided with the pulling rivet bottom outlet matched with staking nail 4, by pulling rivet by C-type steel 5 and dull and stereotyped 2 fastening assemblings, inlay axle sleeve 1 in hole flanging I 11 and hole flanging II 12, its outside is provided with spacer sleeve 3, and L-type part 8 is placed in the two ends of C-type steel 5 and dull and stereotyped 2 assembled; Axle sleeve 1 end face slightly exceeds the first portion 10 of C-type steel and the plane of dull and stereotyped 2, makes the gap between the first portion 10 of air valve blades end face and C-type steel and the plane of dull and stereotyped 2 less, thus when air valve blades is closed between vane end faces and dividing plate leakage rate very little; With bolt through air-valve framework, screw in L-type part 8 tapped hole, the assembling of dividing plate and air-valve framework can be realized.
The C-type steel 5 of this kind of air-valve dividing plate is consistent with air-valve framework sheet material with flat board 2, avoids adopting square steeel tube structure to need the manufacturing processs such as surface treatment, welding and after welding treatment such as holing, zinc-plated, makes simple efficiency high.This kind of air-valve dividing plate component make simple, easy to assembly, vane end faces is little with septum plane gap, be convenient to dividing plate and valve body is fixed and dismantled, diaphragm strength is good, can be used on various material needs compared with in the air-valve of linear leaf.
The above is only preferred implementation of the present utility model; be not limited to the utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
