Abstract
The utility model belongs to flange-type hydraulic connectors technical field, is specifically related to a kind of flange-type hydraulic connectors.Described flange-type hydraulic connectors, comprises a flange body, described flange body comprise flange plate and with described flange plate adpting flange pipe, the step confluce of described flange plate and described flanged pipe is equipped with indent arc groove.The utility model flange-type hydraulic connectors is by being equipped with indent arc groove at the flange plate of flange body and the step confluce of flanged pipe, effectively to be eliminated stress concentration phenomenon by this indent arc groove, reduce stress to concentrate, prevent from, at sharp corner cracking, greatly to extend the working life of part.
Description
Technical field
The utility model belongs to flange-type hydraulic connectors technical field, is specifically related to a kind of flange-type hydraulic connectors.
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-type hydraulic connectors 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-type hydraulic connectors, comprise a flange body, the flanged pipe that described flange body comprises flange plate and is connected with described flange plate, the step confluce of described flange plate and described flanged pipe is equipped with indent arc groove.
Further, the central angle of the circular arc part of described indent arc groove is 110-130 degree, downside wall and horizontal angle be 10-20 degree, the angle of upside wall and vertical line is 10-20 degree.
Preferably, the central angle of the circular arc part of described indent arc groove is 120 degree, downside wall and horizontal angle be 15 degree, the angle of upside wall and vertical line is 15 degree.
The utility model is by being equipped with indent arc groove at the flange plate of flange body and the step confluce of flanged pipe, effectively to be eliminated stress concentration phenomenon by this indent arc groove, reduce stress to 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-type hydraulic connectors;
Figure 2 shows that the enlarged diagram of indent arc groove.
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. 1-2, a kind of flange-type hydraulic connectors, comprise a flange body 1, the flanged pipe 11 that described flange body comprises flange plate 12 and is connected with described flange plate, the step confluce of described flange plate and described flanged pipe is equipped with indent arc groove 13.
It should be noted that, described indent arc groove 13 comprises circular arc part 130 and the upside wall 132 that connects with described circular arc part 130 and downside wall 131, described upside wall 132 and downside wall 131 are a plane, the predetermined angle and described upside wall 132 inwardly has a down dip, described downside wall 131 is upwards outward-dipping predetermined angle on horizontal plane upwards.
Further, the central angle of the circular arc part 130 of described indent arc groove 13 is 110-130 degree, downside wall 131 is 10-20 degree with horizontal A angle, upside wall 132 is 10-20 degree with the included angle B of vertical line.
Preferably, the central angle of the circular arc part of described indent arc groove is 120 degree, downside wall and horizontal angle be 15 degree, the angle of upside wall and vertical line is 15 degree.
The utility model is by being equipped with indent arc groove at the flange plate of flange body and the step confluce of flanged pipe, effectively to be eliminated stress concentration phenomenon by this indent arc groove, reduce stress to concentrate, 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.
