Description
Technical field
The utility model belongs to flange connector technical field, is specifically related to a kind of flange connector.
Background technique
Common flange arrangement easily occurs in long-term high pressure high impulse situation that stress is concentrated, and stress easily concentrates on sharp corner, appears in sharp corner generation cracking and cause losing efficacy after a period of time uses.
Model utility content
The purpose of this utility model Yu Xing certainly above-mentioned technical problem and a kind of flange connector is provided, be intended to solve current common flange arrangement in long-term high pressure high impulse situation, easily occur that stress is concentrated, stress easily concentrates on sharp corner, appears in sharp corner and produce the technical problem ftractureing and cause losing efficacy after a period of time uses.
For achieving the above object, the utility model adopts following technological scheme:
A kind of flange connector, comprise a flange body, the flanged pipe that described flange body is comprised flange plate and is connected with described flange plate by tapered portion, the upper end diameter of described tapered portion is greater than the diameter of lower end, described flange plate is connected by a tapered portion with described flanged pipe, the upper end of described tapered portion is connected by the first arc transition portion with described flanged pipe, and the lower end of described tapered portion is connected by the second arc transition portion with described flange plate.
Further, the circular arc central angle in described first arc transition portion is 10-20 degree, and the circular arc central angle in described second arc transition portion is 70-80 degree.
Preferably, the central angle of the circular arc in described first arc transition portion is 15 degree, and the central angle of the circular arc in described second arc transition portion is 75 degree.
The utility model is connected by a tapered portion with flanged pipe by flange plate, the upper end diameter of described tapered portion is greater than the diameter of lower end, and the upper end of described tapered portion is connected by the first arc transition portion with described flanged pipe, the lower end of described tapered portion is connected by the second arc transition portion with described flange plate; Effectively to be eliminated stress concentration phenomenon by this indent arc groove, reduce stress and concentrate, prevent from, at sharp corner cracking, greatly to extend the working life of part.
Accompanying drawing explanation
Figure 1 shows that the utility model embodiment provides the structural representation of flange connector.
Embodiment
Below, in conjunction with example, substantive distinguishing features of the present utility model and advantage are further described, but the utility model is not limited to listed embodiment.
Refer to shown in Fig. 1, a kind of flange connector, comprise a flange body 1, the flanged pipe 11 that described flange body is comprised flange plate 12 and is connected with described flange plate 12 by a tapered portion 13; The upper end diameter of described tapered portion 13 is greater than the diameter of lower end, and the upper end of described tapered portion 13 is connected by the first arc transition portion 14 with described flanged pipe 11, and the lower end of described tapered portion 13 is connected by the second arc transition portion 15 with described flange plate 12.
Further, the circular arc central angle in described first arc transition portion 14 is 10-20 degree, and the circular arc central angle in described second arc transition portion 15 is 70-80 degree.
Preferably, the central angle of the circular arc in described first arc transition portion is 15 degree, and the central angle of the circular arc in described second arc transition portion is 75 degree.
The utility model is by changing the staircase structural model of flange body into tilted conical surface form, the conical surface is connected with Flange Plane and adopts orthodrome transition, and can effectively eliminate stress concentration phenomenon like this, greatly can extend the working life of part, prevent from, at sharp corner cracking, greatly to extend the working life of part.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
