Abstract
The utility model relates to a flexible pipeline expansion joint and belongs to a pipeline connection accessory. The flexible pipeline expansion joint is characterized by mainly comprising a left flange, a right flange and an expansion ball, each of the left flange and a right flange is a circular disc with mounting holes uniformly distributed on the periphery, the expansion ball is mainly composed of a left ball neck, a ball body, a right ball neck and reinforcing ribs which are made into a whole, the left ball neck and the right ball neck are both cylindrical, the left end of the left ball neck is a flanging circular vertical face, the right end of the right ball neck is also a flanging circular vertical face, the ball body is hollow, and the circular reinforcing ribs are arranged on the outer surface of the ball body. The left ball neck and the right ball neck are inserted into inner holes of the left flange and the right flange correspondingly, and the flanging circular vertical faces correspondingly lean on the outer surfaces of the left flange and the right flange so as to function as gaskets. The flexible pipeline expansion joint is simple and safe in construction, low in cost and good in effect.
Description
Technical field
The utility model belongs to pipeline connecting fitting, especially relates to a kind of flexible pipeline joint.
Background technique
At present, in the pipework construction, because pipe vibration and stretchability are larger, and cause the situation of pipe leakage and damage not within minority, and the situations such as distance (gap) is little between the pipe end, the counterpart difficulty is large appear in the pipe first-aid process, often increased difficulty of construction.
Summary of the invention
The purpose of this utility model is to propose a kind of flexible pipe expansion joint, not only rational in infrastructure, safe and reliable, solve effectively that the gap that occurs in the pipe first-aid process is little, the counterpart difficulty is large and because the vibrations of pipeline and the flexible problem that causes pipe leakage, damage, raising pipeline installation quality.
The purpose of this utility model is achieved like this: a kind of flexible pipe expansion joint, it is characterized in that: this flexible pipe expansion joint is mainly by left flange plate, right flange plate and flexible ball form, the structure of this left flange plate and right flange plate is identical, be circumference uniform distribution and offer the circular disk of mounting hole, this flexible ball is again mainly by the left ball neck of all-in-one-piece processed, spheroid, right ball neck and stiffening rib form, this left ball neck and right ball neck are all cylindrical, and the left end of left ball neck is the annular facade that is flange, and the right-hand member of right ball neck is also for being the annular facade of flange, spheroid be cavity and on the outer surface of spheroid with ring stiffener, to increase the compressive strength of spheroid, the wall thickness that is somebody's turn to do flexible ball can be 8mm-10mm, this flexible ball can be made with pressure-resistant rubber, in the endoporus with left ball neck and right ball neck corresponding insertion left flange plate and right flange plate, and the annular facade correspondence of each flange is abutted on the outer side surface of left flange plate and right flange plate, to play the effect of sealing gasket.
During installation, with end flange dish corresponding be fixedly connected with of bolt with left pipeline and right pipeline, construction not only simply but also safety, and is with low cost effective with left flange plate and right flange plate.
The flexible pipe expansion joint that the utility model proposes, not only rational in infrastructure, safe and reliable, and be very easy to meeting and discussing and being connected of pipeline, and improved the installation quality of pipeline, reduced construction cost.
The flexible pipe expansion joint that now in conjunction with the accompanying drawings and embodiments the utility model is proposed is described further.
Description of drawings
Fig. 1 be the flexible pipe expansion joint that proposes of this institute model utility partly cut open schematic representation.
Among Fig. 1:
1, annular facade 2, left flange plate 3, right flange plate 4. stiffening ribs 5, flexible ball 5-1, left ball neck 5-2, spheroid 5-3, right ball neck.
Embodiment
As can be seen from Figure 1
:A kind of flexible pipe expansion joint, it is characterized in that: this flexible pipe expansion joint is mainly by left flange plate 2, right flange plate 3 and flexible ball 5 form, this left flange plate 2 is identical with the structure of right flange plate 3, be circumference uniform distribution and offer the circular disk of mounting hole, this flexible ball 5 is again mainly by the left ball neck of all-in-one-piece processed 5-1, spheroid 5-2, right ball neck 5-3 and stiffening rib 4 form, this left ball neck 5-1 and right ball neck 5-3 are all cylindrical, and the left end of left ball neck 5-1 is the annular facade 1 that is flange, and the right-hand member of right ball neck 5-3 is also for being the annular facade 1 of flange, spheroid 5-2 be cavity and on the outer surface of spheroid 5-2 with ring stiffener 4, to increase the compressive strength of spheroid 5-2, the wall thickness that is somebody's turn to do flexible ball 5 can be 8mm-10mm, this flexible ball 5 can be made with pressure-resistant rubber, in the endoporus with left ball neck 5-1 and right ball neck 5-3 corresponding insertion left flange plate 2 and right flange plate 3, and annular facade 1 correspondence that makes each flange abuts on the outer side surface of left flange plate 2 and right flange plate 3, to play the effect of sealing gasket.
During installation, with left flange plate 2 and end flange dish corresponding be fixedly connected with of right flange plate 3 usefulness bolts with left pipeline and right pipeline, construction not only simply but also safety, and is with low cost effective.
