Abstract
A corrugated pipe compensator capable of reducing thrust is used for compensating expansion and contraction of a pipeline. The novel corrugated pipe comprises a corrugated pipe (4), wherein the left end of the corrugated pipe is connected with a first connecting pipe (1), the right end of the corrugated pipe is connected with a second connecting pipe (8), the novel corrugated pipe is characterized in that a first annular plate (2) is sleeved on the first connecting pipe, a second annular plate (5) is sleeved on the second connecting pipe, a plurality of pull rods (3) symmetrically penetrate through the first annular plate and the second annular plate, fastening nuts (9) are screwed at the left end of the pull rods (3), the fastening nuts are located on the left side and the right side of the first annular plate, flanges (7) are arranged at the right end of the pull rods (3), springs (6) are sleeved on the pull rods, and the springs are located between the flanges and the second annular plate. The corrugated pipe compensator has the beneficial effects that the spring has compression force on the corrugated pipe, and the pressure of the fluid medium in the corrugated pipe can be partially or completely counteracted by the spring, so that the thrust of the corrugated pipe compensator on external equipment can be greatly reduced, and the damage to the external equipment is avoided.
Description
Technical Field
The utility model relates to a corrugated pipe compensator which is used for compensating expansion caused by heat and contraction caused by cold of a pipeline.
Background
When the corrugated pipe compensator works, the corrugated pipe bears the pressure of fluid medium, the corrugated pipe can generate axial thrust to external equipment connected with the corrugated pipe under the action of the fluid pressure, and the external equipment can be damaged when the thrust is overlarge.
Disclosure of utility model
The utility model aims to solve the technical problems of reducing the axial thrust of a corrugated pipe compensator
The utility model solves the technical scheme that the corrugated pipe compensator capable of reducing thrust comprises a corrugated pipe 4, wherein the left end of the corrugated pipe is connected with a first connecting pipe 1, the right end of the corrugated pipe is connected with a second connecting pipe 8, and the corrugated pipe compensator is characterized in that a first annular plate 2 is sleeved on the first connecting pipe, a second annular plate 5 is sleeved on the second connecting pipe, a plurality of pull rods 3 symmetrically penetrate through the first annular plate and the second annular plate, fastening nuts 9 are screwed at the left end of each pull rod 3, the fastening nuts are positioned at the left side and the right side of the first annular plate, flanges 7 are arranged at the right end of each pull rod 3, springs 6 are sleeved on the pull rods, and the springs are positioned between the flanges and the second annular plates.
The corrugated pipe compensator has the beneficial effects that the spring has compression force on the corrugated pipe, and the pressure of the fluid medium in the corrugated pipe can be offset by the spring to a part, so that the thrust of the corrugated pipe compensator on external equipment can be greatly reduced, and the damage to the external equipment is avoided.
Drawings
Fig. 1 is a schematic structural view of the present invention.
The reference signs are as follows: 1-first connecting pipe, 2-first annular plate, 3-pull rod, 4-bellows, 5-second annular plate, 6-spring, 7-flange, 8-second connecting pipe, 9-fastening nut and 10-limit nut.
Description of the embodiments
The utility model provides a can reduce bellows compensator of thrust, it includes bellows 4, the left end and the first takeover 1 sealing welding of bellows, the right-hand member and the second takeover 8 sealing welding of bellows, it has first annular plate 2 to overlap on first takeover, first annular plate and first takeover welding, it has second annular plate 5 to overlap on the second takeover, first annular plate and first takeover welding, many pull rods 3 run through in first annular plate and second annular plate symmetrically, the left end of pull rod 3 revolves has fastening nut 9, fastening nut is located the left and right sides of first annular plate, the right-hand member of pull rod 3 has flange 7, the cover has spring 6 on the pull rod, the spring is located between flange and the second annular plate, the flexible volume of spring is greater than bellows compensator's compensation volume.
The pre-pressure of the spring to the corrugated pipe can be adjusted by adjusting the fastening nuts on the left side and the right side of the first annular plate, and the pre-pressure is 1/2 to 2/3 of the rated working pressure of the corrugated pipe compensator.
The pull rod is further screwed with a limit nut 10, and the limit nut 10 can be contacted with the left end face of the second annular plate; the limiting nut has the function of preventing the pre-pressure of the spring from pressing the corrugated pipe; the limiting nut should be remote from the second annular plate during normal operation.
When in use, the corrugated pipe compensator is connected in series in the pipeline, and then the limit nut is far away from the second annular plate. Most of the axial thrust generated by the fluid medium in the bellows can be counteracted by the spring; when the pipeline expands with heat and contracts with cold, the corrugated pipe stretches and contracts with the pipeline to realize compensation.
Claims (2)
1. Can reduce bellow compensator of thrust, it includes bellows (4), the left end and the first takeover (1) of bellows are connected, the right-hand member and the second takeover (8) of bellows are connected, characterized by has cup jointed first annular plate (2) on first takeover, cup jointed second annular plate (5) on the second takeover, many pull rods (3) run through in first annular plate and second annular plate symmetrically, the left end of pull rod (3) soon has fastening nut (9), fastening nut is located the left and right sides of first annular plate, the right-hand member of pull rod (3) has flange (7), the cover has spring (6) on the pull rod, the spring is located between flange and the second annular plate.
2. The bellows compensator capable of reducing thrust according to claim 1, wherein the draw rod is screwed with a limit nut (10) which can be in contact with the left end face of the second annular plate.
