Abstract
The utility model relates to a kind of compensators, including bellows, the both ends of bellows respectively connect an end pipe, a connecting flange is socketed outside each end pipe, it is connected between two connecting flanges by Double-head telescopic bar, the both ends of the Double-head telescopic bar are respectively provided with a ball, and the periphery of the connecting flange sets that there are three the hangers in equilateral triangle arrangement, each hangers is equipped with a ball bowl, and the ball elastic conjunction is in ball bowl.The beneficial effects of the utility model are: two big pipe joints of deviation can be connected, the distance change when pipeline expands with heat and contract with cold between adaptive two pipe joint.
Description
Technical field
The utility model relates to compensator technical field more particularly to a kind of compensators.
Background technique
Compensator is made of attachmentes such as the bellows and end pipe, bracket, flange, the conduits that constitute its operative body.Belong to one
Kind compensating element,.It is cold by heat expansion with absorption line, conduit, container etc. using effective dilatation of its operative body bellows
The reasons such as contracting and change in size or compensation pipes, conduit, the axial of container etc., transverse direction and the angular displacement generated.It can also be used for
Noise-and-vibration-reduction.It is widely used in modern industry.In heat supply, when heat supply pipeline heats up in order to prevent, due to thermal stretching or temperature
Stress and cause pipe deforming or destruction, need that compensator is arranged on pipeline, to compensate the thermal stretching of pipeline, to reduce pipe
The stress of wall and act on the active force on valve member or supporting structure.
Utility model content
Utility model aims to solve the connectivity problems between the big pipe joint of two deviations, provide a kind of compensation
Device can connect two big pipe joints of deviation.
To realize above-mentioned technical purpose and the technique effect, the utility model is achieved through the following technical solutions:
A kind of compensator, including bellows, the both ends of bellows respectively connect an end pipe, are socketed one outside each end pipe
Connecting flange is connected by Double-head telescopic bar between two connecting flanges, and the both ends of the Double-head telescopic bar are respectively provided with a ball,
The periphery of the connecting flange is set there are three the hangers in equilateral triangle arrangement, and each hangers is equipped with a ball bowl, institute
Ball elastic conjunction is stated in ball bowl.
Wherein, the Double-head telescopic bar includes two piston rods and one with piston tube, one end of the piston rod be ball,
The other end is rubber piston head, and the both ends that the rubber piston head of two piston rods is located at piston tube form a closed chamber
Room is filled with nitrogen in the chamber.
Wherein, the compressed volume of the nitrogen accounts for the 50% ~ 80% of chamber.
Wherein, the compressed volume of the nitrogen accounts for the 70% of chamber.
Wherein, the bellows is made of polytetrafluoroethylene (PTFE) or propylene oxide.
Wherein, one layer of spring steel sleeve or stainless steel outer sleeve are wrapped up outside the bellows.
Wherein, support ring is installed on the inside of the bellows wave crest, wraps up one layer of material identical as bellows outside the support ring
Crust made of expecting.
The beneficial effects of the utility model are: two big pipe joints of deviation can be connected, when pipeline expands with heat and contract with cold
Distance change between adaptive two pipe joint.
