Problems solved by technology

Its disadvantages are: the fluid medium will generate a large pressure thrust in the bellows, which is easy to have adverse effects on the connected equipment or pipeline support; at the same time, the self-weight of the bellows compensator is easy to deform the bellows and cause instability.

Embodiment Construction

[0009] The specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0010] The bellows compensator includes a balance bellows 5, and a first bellows 3 and a second bellows 7 are respectively welded at both ends of the balance bellows through a middle joint 51. The diameter of the first bellows is the same as the diameter of the second bellows. The pipe diameters are equal, and the pipe diameter of the balance bellows is larger than that of the first bellows. The left end of the first corrugated pipe is welded with a left joint 31, one end of the left joint is welded with a first pipe 1, the right end of the second corrugated pipe is welded with a right joint 71, and one end of the right joint is welded with a second pipe 8, the first pipe and the second pipe It is used to connect with the pipeline. When the pipeline expands or contracts linearly, the gap between the facing end faces of the first connecting pipe 1 and th...

Abstract

The invention relates to a bellows compensator, which comprises a balance bellows (5), a first bellows (3) and a second bellows (7) are welded onto two ends of the balance bellows (5) through joints; a left end ring (21) and a right end ring (22) are respectively welded onto the joints on the two ends of the balance bellows; a first ear plate (2) is welded onto the left side of the first bellows; a second ear plate (23) is welded onto the right side of the second bellows; a plurality of first pull rods (4) are symmetrically arranged between the first ear plate and the right end ring (22); a plurality of second pull rods (41) are symmetrically arranged between the second ear plate and the left end ring (21); the pipe diameter of the balance bellows is larger than the pipe diameters of the first bellows and the second bellows. Thrust generated by fluid pressure in the balance bellows is larger than thrust in the first bellows and the second bellows, so that the thrust generated by the fluid pressure is balanced; a first joint pipe extends rightwards to the middle part of the right joint, so that the bellows is prevented from being deformed and instable.

Description

technical field [0001] The invention relates to a bellows compensator, which comprises a balance bellows, and a first bellows and a second bellows connected at both ends of the balance bellows. The second pipe is connected to the heat pipe to compensate the linear expansion of the heat pipe. Background technique [0002] The thermal pipeline will produce linear expansion or linear contraction due to thermal expansion and contraction, which affects the safe operation of the thermal pipeline. Usually, a bellows compensator is used to compensate the thermal expansion and contraction of the thermal pipeline. In order to make the bellows compensator have enough expansion and contraction, multiple bellows are used to connect together. The disadvantage is that the fluid medium will generate a large pressure thrust on the bellows, which is easy to have an adverse effect on the connected equipment or pipeline supports; at the same time, the self-weight of the bellows compensator wil...
