Description

Corrugated pipe compensator with leakage repairing structure

Technical Field

The utility model particularly relates to a corrugated expansion joint ware mending-leakage technique specifically is a corrugated expansion joint ware with mending-leakage structure.

Background

The corrugated pipe is a tubular elastic sensitive element which is formed by connecting foldable corrugated sheets along the folding and stretching direction. The corrugated pipe has wide application in instruments and meters, and is mainly used as a measuring element of a pressure measuring instrument to convert pressure into displacement or force. The corrugated pipe has thin pipe wall and high sensitivity, and the measurement range is from tens of Pa to tens of MPa. Its open end is fixed, its sealed end is in free state, and its elasticity is increased by using auxiliary helical spring or reed. When working, the pipe is extended along the length direction under the action of internal pressure, so that the movable end generates displacement in a certain relation with the pressure. The movable end drives the pointer to directly indicate the pressure. Bellows are often combined with displacement sensors to form pressure sensors that output an electrical quantity, sometimes also acting as isolation elements. The response speed of the bellows is slower than that of the bourdon tube because of the large volume change required for the expansion of the bellows. The bellows is adapted to measure low pressure.

Compensators are also conventionally called expansion joints, or expansion joints. It is composed of bellows (an elastic element) and its working body, end pipe, support, flange and guide pipe. Belongs to a compensating element. The effective telescopic deformation of the working body corrugated pipe is utilized to absorb the dimensional change of pipelines, conduits, containers and the like caused by expansion and contraction due to heat and the like or compensate the axial, transverse and angular displacement of the pipelines, the conduits, the containers and the like. And can also be used for noise reduction and vibration reduction. Has wide application in modern industry. In order to prevent the pipeline from deforming or breaking due to thermal elongation or temperature stress when the heating pipeline is heated, a compensator is required to be arranged on the pipeline to compensate the thermal elongation of the pipeline, so that the stress of the pipeline wall and the acting force acting on the valve member or the bracket structure are reduced.

Cn202120131612.X discloses a corrugated pipe compensator, which comprises a corrugated pipe compensator main body, wherein a protection mechanism is mounted on a surface of the corrugated pipe compensator main body, the protection mechanism includes two groups of first protection sleeves, the two groups of first protection sleeves are all sleeved on the surface of the corrugated pipe compensator main body, one sides of the two groups of first protection sleeves, which are far away from each other, are all fixedly connected with one side of the corrugated pipe compensator main body, one sides of the two groups of first protection sleeves, which are close to each other, are all provided with movable grooves, a second protection sleeve is sleeved in the middle of the surface of the corrugated pipe compensator main body, two sides of the second protection sleeve respectively extend into the two groups of movable grooves, a sponge cushion is sleeved on the surface of the corrugated pipe compensator main body, and a pre-fixing mechanism is arranged on the surface of the corrugated pipe compensator main body;

the corrugated pipe compensator can only be used for leveling places, can not be used in places needing bending or turning, has certain limitation, and can not meet the use requirements of people on the corrugated pipe compensator; therefore, the corrugated pipe compensator with the leakage repairing structure can make up the defects of the corrugated pipe compensator, can be applied to places with more requirements, meets the requirements, has the leakage repairing function, avoids leakage inside, reduces the harm caused by leakage, improves the using time, and reduces the replacement cost.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a corrugated expansion joint with mending-leakage structure to the corrugated expansion joint who proposes in solving the background art is that one kind can only be used for leveling the local compensator, and the place that bends or need turn round at many needs can not be used, has certain limitation, can not satisfy the problem of people to corrugated expansion joint's operation requirement.

In order to achieve the above object, the utility model provides a following technical scheme:

a corrugated pipe compensator with a leakage repairing structure comprises a corrugated pipe; a flange plate is arranged on a connecting head at one end of the corrugated pipe; the flange plate is provided with holes for connecting bolts and nuts in a threaded manner; the flange plate is connected with a compensator through bolts and nut threads.

As a further technical scheme of the utility model, the bellows on the ring flange that sets up and the ring flange that sets up on the compensator between be provided with the gasket.

As a further technical scheme of the utility model, the compensator on ordinary bellows be provided with crest and trough equally.

As a further technical scheme of the utility model, the outside mending leakage bellows of compensator sealed with the laminating of inside ordinary bellows.

As a further technical proposal of the utility model, two ends of the compensator are provided with flange plates; and the compensator is provided with a hole for connecting the bolt and the nut in a threaded manner.

Compared with the prior art, the beneficial effects of the utility model are that:

1. in the utility model, because the common corrugated pipe in the compensator is also provided with the wave crest and the wave trough, the situation that gas or liquid enters the compensator and then is blocked can not occur; and the compensator may be different depending on the used scenario. The bending machine can be applied to places needing bending or needing turning, and meets the use requirements of people.

2. The utility model can improve the sealing performance between the corrugated pipe and the compensator and prevent leakage caused by poor sealing due to the gasket arranged between the flange arranged on the corrugated pipe and the flange arranged on the compensator;

3. the utility model discloses, because the compensator is provided with two-layerly, take place to reveal or damaged when inside ordinary bellows, when personnel failed in time to discover to change, outside mending leakage bellows can continue to support the use of this compensator, and is long when having improved the use, has reduced the cost of changing.
