Technical Field

[0001] The utility model relates to a pipeline connecting sleeve, in particular to a high-pressure-resistant full-width sleeve. Background Art

[0002] A sleeve is a connector used to connect pipes. Currently, sleeves suitable for connecting fiberglass reinforced plastic (FRP) pipes are typically constructed of a fiberglass outer layer and a full-width, integral rubber sleeve. To reduce weight and save costs, existing sleeves typically have thinner walls, which can easily deform and break when subjected to high pressure during stacking and use. Furthermore, pressure during use transfers this pressure to the pipe, where the pipe connects to the sleeve at the port, which is more susceptible to damage under pressure. Therefore, a high-pressure-resistant, full-width sleeve is proposed. Utility Model Content

[0004] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: a high-pressure-resistant full-width sleeve, comprising a sleeve body composed of a full-width integral rubber in an inner layer and a stainless steel sleeve on the outside of the full-width integral rubber; its characteristic is that it also includes a pressure-resistant structure arranged on the stainless steel sleeve for enhancing the pressure resistance of the sleeve body; the pressure-resistant structure includes a plurality of reinforcing ribs arranged on the inner side of the sleeve; the full-width integral rubber is provided with a limiting groove that is adapted to the reinforcing ribs on the inner side of the stainless steel sleeve and serves to limit the position of the full-width integral rubber installed in the stainless steel sleeve.

[0005] Further preferably, the middle portion of the full-width integral rubber is further provided with a block which limits the position of the pipe inserted into the sleeve body and prevents the ends of the pipe on both sides of the sleeve body from colliding.

[0007] Further preferably, the stopper is provided with a trapezoidal groove adapted to the inner ring of the block, and the thickness of the stopper is the same as that of the block.

[0008] Further preferably, the full-width integral rubber inner ring is configured to be corrugated to form a plurality of wave crests, and multiple seals are formed between the pipe inserted into the inner body of the stainless steel sleeve and the plurality of wave crests.

[0009] Further preferably, the compression ratio of the full-width integral rubber (2) is 50-56%.

[0010] The beneficial effects of the present invention are as follows: through the setting of the pressure-resistant structure, corresponding reinforcing ribs are set at several positions on the inner side of the stainless steel sleeve to enhance the pressure resistance of the stainless steel sleeve, thereby enhancing the pressure resistance of the entire sleeve body, avoiding the deformation of the sleeve body after being pressurized and applying pressure to the pipe port, causing damage to the pipe port and the sleeve body due to pressure, resulting in leakage and other problems, thereby improving the service life of the sleeve body and the pipeline.

[0015] Below we further explain the high pressure-resistant full-width sleeve described in the present invention with reference to the accompanying drawings.

[0016] It should be noted that all directional indications such as up, down, left, right, front, back, etc. in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components in a certain specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly.

[0017] In this utility model, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; it can mean mechanical connection or electrical connection; it can mean direct connection or indirect connection through an intermediate medium; it can mean internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0018] See Figure 1-3As shown in the figure, a high-pressure-resistant full-width sleeve includes a sleeve body 1 composed of a full-width integral rubber 2 on the inner layer and a stainless steel sleeve 3 on the outer side of the full-width integral rubber 2; it is characterized by further including a pressure-resistant structure provided on the stainless steel sleeve 3 for enhancing the pressure resistance of the sleeve body 1; the pressure-resistant structure includes a plurality of reinforcing ribs 4 provided on the inner side of the sleeve 3; the full-width integral rubber 2 is provided with a limiting groove 5 that is adapted to the reinforcing ribs 4 on the inner side of the stainless steel sleeve 3 and serves to limit the position of the full-width integral rubber 2 installed in the stainless steel sleeve 3;

[0019] The full-width integral rubber is bonded to the stainless steel material, and the stainless steel sleeve 3 is made of stainless steel, which can increase the effective thickness of the pipeline;

[0020] The stainless steel sleeve 3 and the full-width integral rubber 2 are structurally bonded using an environmentally friendly adhesive, resulting in higher bonding strength;

[0021] By setting up the pressure-resistant structure, a number of reinforcing ribs 4 are set on the inner side of the stainless steel sleeve 3 to enhance the pressure resistance of the stainless steel sleeve 3, thereby enhancing the pressure resistance of the entire sleeve body 1, avoiding the sleeve body 1 from deforming after being compressed and applying pressure to the pipe port, causing damage to the pipe port and the sleeve body 1 due to pressure, resulting in leakage and other problems, thereby improving the service life of the sleeve body 1 and the pipeline;

[0022] At the same time, the cooperation between the reinforcing rib 4 on the inner side and the limiting groove 5 set on the full-width integral rubber 2 also has a limiting effect on the installation of the full-width integral rubber 2 on the inner wall of the stainless steel sleeve 3. When inserting the pipe, it can avoid the full-width integral rubber 2 from moving in the stainless steel sleeve 3 due to the resistance during the insertion of the pipe, thereby causing the full-width integral rubber 2 to be disconnected from the stainless steel sleeve 3, thereby enhancing the connection firmness between the full-width integral rubber 2 and the stainless steel sleeve 3.

[0023] In one embodiment, the middle portion of the full-width integral rubber 2 is further provided with a block 6 which limits the position of the pipe inserted into the sleeve body 1 and prevents the ends of the pipe on both sides of the sleeve body 1 from colliding.

[0024] By setting the block 6, the position of the pipe inserted into the stainless steel sleeve 3 is limited, avoiding inconsistent insertion distances of the pipes on both sides and affecting the stability of the connection between the pipe and the sleeve body 1. At the same time, it can also separate the pipes on both sides to avoid collision between the pipe ports when inserting the pipes and causing damage.

[0025] In one embodiment, the inner circle of the block 6 is trapezoidal in shape, and a number of blocks 7 are installed on the inner circle of the block 6 to prevent the pipe from passing over the block 6 when inserted; the setting of the block 7 prevents the pipe from passing over the block 6 due to excessive extrusion force when inserted into the sleeve body 1.

[0026] In one embodiment, the stopper 7 is provided with a trapezoidal groove 8 that is adapted to the inner ring of the block 6, and the thickness of the stopper 7 is the same as that of the block 6; by setting the inner end of the block 6 into a trapezoid, and providing a trapezoidal groove 8 that is adapted to the inner ring of the block 6 on the stopper 7, the installation position of the stopper 7 is limited by the setting of the trapezoidal groove 8, and the stopper 7 is installed on the inner ring of the block 6 by gluing. At the same time, by setting the thickness of the stopper 7 to be the same as that of the block 6, the purpose is to enable the port of the pipeline to fit with the end faces of the block 6 and the block 7 after installation, so as to avoid being blocked by the block 7 and causing its port to be unable to fit, resulting in the pipeline being unable to be inserted and installed in place and affecting the sealing.

[0027] In one embodiment, the inner ring of the full-width integral rubber 2 is configured to be corrugated, forming a plurality of wave crests 9. After the pipeline is inserted into the inner body of the stainless steel sleeve 3, the plurality of wave crests 9 on the full-width integral rubber 2 are squeezed to form multiple seals between the wave crests 9 and the pipeline, thereby enhancing the sealing performance and improving the installation firmness.

[0028] In one embodiment, the compression ratio of the full-width integral rubber is 50-56%, and the sealing performance is better.

[0029] When the utility model is in use: first, a plurality of blocks 7 are installed on the block 6 by gluing, and are positioned and installed on the trapezoidal inner ring of the block 6 through the trapezoidal groove 8 during rotation, and then one end of the pipe is pushed into one side of the sleeve body 1 by the pipe pushing equipment. During the pushing process, the pipe squeezes a plurality of peaks 9 on the full-width integral rubber 2 until the end face of the pipe is fitted with the end face of the block 6 and installed in place, and then one end of the other pipe is pushed into the other side of the sleeve body 1 in the same way.

[0030] The protection scope of the present invention is not limited to the above embodiment and its variations. Conventional modifications and replacements made by those skilled in the art based on the contents of this embodiment fall within the protection scope of the present invention.
