Abstract
A weight-reduction flange comprises a flange body, a connecting pipe opening and mounting holes, and is characterized in that a circular weight-reduction ring is further arranged on the outer sides of the mounting holes; the depth of the circular weight-reduction ring is one third of the thickness of the flange; the diameter of an excircle of the circular weight-reduction ring is four fifths of that of the weight-reduction flange; the diameter of an inner circle of the circular weight-reduction ring is three fifths of that of the weight-reduction flange; the weight-reduction flange is subjected to nickel-plating or zinc-plating corrosion prevention treatment. Since the circular weight-reduction ring is arranged on the outer side of the flange to reduce the weight of the flange, the purpose of reducing the weight of the flange is achieved, and the structure arrangement and the strength requirement of the flange are ensured at the same time; moreover, via the structural design, the flange is simple in manufacturing, and the processing cost is reduced.
Description
Technical field
The present invention relates to a kind of loss of weight flange, belong to the pipeline connection area.
Background technique
Flange is widely used in pipeline connects, pipeline generally is applied to the conveying of liquid and gas, in the long-distance large pipeline is carried, for easy for installation and saving purpose, reduce the weight of flange itself and do not affect the structural requirement of flange itself, just seem particularly important.Although the loss of weight flange is also arranged, just loss of weight is carried out in part, and, mostly adopting via design, this may affect the structure arrangement of flange, as affects the size of flange facing, and other performances of flange reduce; Simultaneously, through hole also may affect the intensity of flange itself, causes reduce its working life.Therefore, be necessary to design and a kind ofly can reduce flange weight, and don't affect the flange of its structure arrangement and requirement of strength.
Summary of the invention
For the deficiencies in the prior art, the purpose of this invention is to provide and a kind ofly can reduce flange weight, guarantee again the loss of weight flange of its structure arrangement and requirement of strength.
For achieving the above object, the present invention realizes by following technological means:
A kind of loss of weight flange, comprise flange body, take over mouth and mounting hole, it is characterized in that: in the described loss of weight flange mounting hole outside, also be provided with the loss of weight annulus;
Preferably, the degree of depth of described loss of weight annulus is 1/3rd of flange thickness;
Preferably, the diameter of described loss of weight annulus cylindrical is 4/5ths of loss of weight flange diameter, and in described loss of weight annulus, diameter of a circle is 3/5ths of loss of weight flange diameter.
Preferably, described loss of weight flange process degree nickel or galvanized anticorrosive erosion are processed.
The invention has the beneficial effects as follows: take to offer the loss of weight annulus in the flange outside and reduce the weight of flange own, both reached the purpose that alleviates flange weight, structure arrangement and the requirement of strength of flange itself have been guaranteed again simultaneously, simultaneously, this structural design, flange itself is made simple, reduced processing cost.
Description of drawings
Fig. 1 is structural representation of the present invention.
The implication of drawing reference numeral is as follows:
1 flange body, 2 take over mouth, 3 mounting holes, 4 loss of weight annulus.
Embodiment
Below in conjunction with Figure of description, the present invention is further illustrated.
As shown in Figure 1, a kind of loss of weight flange, comprise flange body, take over mouth and mounting hole, it is characterized in that: in the described loss of weight flange mounting hole outside, also be provided with the loss of weight annulus, can effectively reduce flange weight, do not affect simultaneously structure arrangement and the requirement of strength of flange, make the flange manufacturing simple, save production cost.
Preferably, the degree of depth of described loss of weight annulus is 1/3rd of flange thickness, this Thickness Design, the unlikely requirement of strength that affects flange;
Preferably, the diameter of described loss of weight annulus cylindrical is 4/5ths of loss of weight flange diameter, and in described loss of weight annulus, diameter of a circle is 3/5ths of loss of weight flange diameter, considers the requirement of strength of flange itself, and the width of this annulus is unsuitable excessive;
Preferably, described loss of weight flange process degree nickel or galvanized anticorrosive erosion are processed, and can make flange be applicable to corrosive environment, enlarge use occasion and the working life of flange.。
Above demonstration and described basic principle of the present invention, major character and advantage.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
