Description

Technical Field

[0001] The utility model relates to the technical field of pipeline corrugated compensators, and more specifically to a stainless steel water pipe annular pressure type pipeline corrugated compensator. Background Art

[0002] Pipe compensators are also called expansion joints or expansion joints. They are mainly used to compensate for the thermal expansion and contraction caused by temperature changes in pipes. If the pipe cannot expand or contract freely when the temperature changes, thermal stress will be generated inside the pipe. This stress must be considered in the pipe design, otherwise it is likely to cause the pipe to rupture and affect normal production. There are many types of pipe compensators, including pipe corrugated compensators. Commonly used pipe corrugated compensators are cumbersome and time-consuming to install, and most of the compensators are made of non-stainless steel, and their service life may not meet people's usage needs.

[0003] For example, announcement No. CN219082580U discloses a pressure-sealed leak-proof device for a corrugated compensator of a heating pipe, which includes a heating pipe, a corrugated compensator body and a ring plate sleeved on the corrugated compensator body. One end of the heating pipe is arranged on the inner side of the ring plate, an annular groove is provided on the inner wall surface of the ring plate, and a telescopic air bag is provided inside the annular groove.

[0004] It can be seen from the above-mentioned public scheme that the two ends of the corrugated compensator body are fixed by connecting flanges and bolts when connected. Since the construction workers manually rotate and fix the bolts one by one, it is not only time-consuming, but also increases the labor intensity of the construction workers, making the installation of the corrugated compensator body more cumbersome and time-consuming, reducing the assembly efficiency. In addition, the corrugated compensator body is made of non-stainless steel material. During use, when the medium flows through, the grooves formed inside the corrugated part are easily eroded by the medium and wear faster, which makes the corrugated part of the corrugated compensator body easy to wear through and leak, so that the service life of the corrugated compensator body is limited. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide a stainless steel water pipe ring-pressed pipe corrugated compensator. The stainless steel water pipe ring-pressed pipe corrugated compensator can be quickly connected to the water pipe joint by ring pressing when the pipe corrugated compensator is connected, through the set stepped feed joint and discharge joint. The operation is simple, which greatly improves the assembly efficiency of the pipe corrugated compensator. The pipe corrugated compensator body and sealing block made of stainless steel material can not only increase the service life of the pipe corrugated compensator, but also increase the sealing and leak-proof performance of the corrugated part.

[0024] Example 1

[0025] See also Figure 1-4, a stainless steel water pipe annular pressure type pipeline bellows compensator, including a pipeline bellows compensator body 1, which is made of stainless steel material. Compared with the original material products, the service life of the pipeline bellows compensator can be increased. The two ends of the pipeline bellows compensator body 1 are connected to the water pipes to compensate for the thermal expansion and contraction caused by temperature changes in the pipeline. Its working principle is well known to those skilled in the art and will not be described in detail here. A pressurized plugging device can also be installed at one end of the pipeline bellows compensator body 1. An axially penetrating channel 15 is provided in the center of the pipeline bellows compensator body 1. A feed connector 11 and a discharge connector are provided at both ends of the pipeline bellows compensator body 1. The head 12, the stepped feed joint 11 and the discharge joint 12, after being pressed against the water pipe ring, make the connection area non-planar, thereby improving the connection stability and firmness. One end of the feed joint 11 is provided with a first groove 111 and a second groove 112 which are coaxial and concentric with the channel 15, the inner diameter of the first groove 111 is larger than the inner diameter of the channel 15, the inner diameter of the second groove 112 is larger than the inner diameter of the first groove 111, and one end of the discharge joint 12 is provided with a third groove 121 and a fourth groove 122 which are coaxial and concentric with the channel 15. A corrugated portion 13 is provided in the middle of the pipeline corrugated compensator body 1, and a corrugated groove 14 is formed inside the corrugated portion 13, and a sealing block 2 is fixedly connected to the surface of the corrugated portion 13.

[0026] The shapes of the feed joint 11 and the discharge joint 12 are both stepped. The surface of the feed joint 11 is provided with a first slope 113 and a second slope 114, and the surface of the discharge joint 12 is provided with a third slope 123 and a fourth slope 124. The first slope 113, the second slope 114, the third slope 123 and the fourth slope 124 can increase the tightness of the fit with the inner wall of the water pipe. The first slope 113 and the third slope 123 have the same size and shape, and the second slope 114 and the fourth slope 124 have the same size and shape, which can increase the fitting area between the surface of the stepped joint and the inner wall of the water pipe.

[0027] The sealing block 2 is made of elastic corrosion-resistant sealing rubber, and a corrugated sealing groove 21 is formed inside the sealing block 2. Both ends of the sealing groove 21 are connected with sealing holes 22. The sealing block 2 can seal the outside of the corrugated part 13 to avoid leakage of the medium after the corrugated part 13 is perforated. The first groove 111 and the third groove 121 have the same size and shape, and the second groove 112 and the fourth groove 122 have the same size and shape, which facilitates the molding of the feed joint 11 and the discharge joint 12 at both ends of the pipeline corrugated compensator.

[0028] The stainless steel water pipe ring-pressed pipe corrugated compensator is installed after the water pipe reaches a certain length. First, one end of the pipe corrugated compensator body 1 is plugged into one end of the laid water pipe, and then the water pipe and the feed joint 11 are fixed by ring pressing through a ring pressing mold. Then the water pipe to be laid is laid, and one end of the water pipe and the discharge joint 12 of the pipe corrugated compensator body 1 are fixed by ring pressing through a ring pressing mold, so that the pipe corrugated compensator body 1 is located between the two water pipes, and the installation of the pipe corrugated compensator is completed. By setting the stepped feed joint 11 and the discharge joint 12, the pipe corrugated compensator can be quickly connected to the water pipe joint by ring pressing when connected. The operation is simple, which greatly improves the assembly efficiency of the pipe corrugated compensator. The pipe corrugated compensator body 1 and the sealing block 2 made of stainless steel material can not only increase the service life of the pipe corrugated compensator, but also increase the sealing and leak-proof performance of the corrugated part 13.
