Description

Technical Field

[0001] This utility model relates to the field of pipeline technology, and in particular to a pressure-resistant bend pipe. Background Technology

[0002] A pressure-resistant bend is a pipe fitting specifically designed to withstand high internal fluid pressure. It is typically used to change the direction of a pipeline or connect straight pipe sections in different directions. Pressure-resistant bends have sufficient strength and toughness to maintain their shape and function without deformation or cracking under high pressure. In long-distance pipelines, pressure-resistant bends are needed to connect straight pipes in different directions in order to adjust the route or avoid specific areas. In existing technologies, flange connections are usually used when connecting to straight pipes, which is extremely inconvenient when pipeline replacement is required. It requires the disassembly of a large number of bolts and nuts, which is cumbersome and time-consuming. If the bolts are rusty or stripped, it will increase the difficulty of disassembly and slow down the replacement process. Utility Model Content

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Example 1

[0029] Reference Figures 2-6This is the first embodiment of the present utility model. This embodiment provides a pressure-resistant bend, which includes a connecting component 200, a positioning component 300, and a main component 100. The three components work together to eliminate the need to disassemble a large number of bolts and nuts during pipeline maintenance and replacement, avoiding tedious and time-consuming operations. It also eliminates the problems of bolt rust, stripped threads causing difficulty in disassembly and slow progress, and can greatly improve the efficiency of maintenance and replacement.

[0030] The connecting assembly 200 includes a connector 201, which includes a connecting clamp 201a, a push plate 201b, a push rod 201c, and a movable plate 201d. The push plate 201b is fixed to the top of the connecting clamp 201a, the push rod 201c is fixed to one side of the push plate 201b, and the movable plate 201d is fixed to one end of the push rod 201c.

[0031] The connecting clamp 201a is fixed to one end of the bend body 101. By placing other connecting pipes inside the connecting clamp 201a, they are engaged with the bend body 101. By moving the moving plate 201d, the moving plate 201d drives the push rod 201c to move. The movement of the push rod 201c can drive the push plate 201b to move. At this time, the movement of the push plate 201b can cause the two ends of the connecting clamp 201a to tighten inward, thereby fixing the bend body 101 and other connecting pipes. There are two push plates 201b, two push rods 201c, and two moving plates 201d, all of which are set on the connecting clamp 201a.

[0032] The positioning component 300 is disposed on the connector 201 and includes the positioning component 301, including the positioning wheel 301a, the positioning strip 301b and the pull rod 301c. The positioning wheel 301a is disposed on the connector 201, the positioning strip 301b is located on one side of the positioning wheel 301a, and the pull rod 301c is fixed to one end of the positioning strip 301b.

[0033] A beveled groove corresponding to the positioning strip 301b is provided on the positioning wheel 301a. The positioning strip 301b is set as a bevel. By rotating the positioning wheel 301a, the two moving plates 201d can be driven to move towards each other, thereby tightening the two ends of the connecting hoop 201a inward. At this time, the positioning strip 301b will not limit the positioning wheel 301a. The setting of the positioning strip 301b can limit the positioning wheel 301a in one direction, preventing the positioning wheel 301a from reversing and causing the connecting hoop 201a to loosen. When it is necessary to disconnect the connection to the bend body 101, the pull rod 301c is pulled. The pull rod 301c can drive the positioning strip 301b to move and separate from the positioning wheel 301a, thereby releasing the limit on the positioning wheel 301a. By reversing the positioning wheel 301a, the moving plate 201d can return to its original position, and the connecting hoop 201a can be loosened.

[0034] Example 2

[0035] Reference Figures 2-6 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0036] Specifically, the connecting component 200 also includes a movable part 202, which is disposed on the movable plate 201d. A cam 202a is disposed on one side of the movable plate 201d, and a support plate 202b is disposed at the bottom of the cam 202a. The support plate 202b and the cam 202a are rotatably connected by a rotating shaft, and the support plate 202b is fixed to the top of the connecting hoop 201a.

[0037] When the positioning wheel 301a rotates, it can drive the cam 202a to rotate. The rotation of the cam 202a can squeeze the two moving plates 201d, thereby causing them to move towards each other. The support plate 202b is fixed to the top of the connecting hoop 201a and is movably connected to the other end of the top of the connecting hoop 201a. The support plate 202b can support the cam 202a and prevent the cam 202a from shifting.

[0038] Specifically, a torsion spring 202c is fixed to the bottom of the cam 202a, and the torsion spring 202c is fixed to the top of the support plate 202b.

[0039] When the cam 202a rotates and presses the moving plate 201d, a torsional force can be applied to the torsion spring 202c. When it is necessary to return the moving plate 201d to its original position, the limit on the positioning wheel 301a is released. Then, the force of the torsion spring 202c rotating can drive the cam 202a to rotate, thereby releasing the pressure on the moving plate 201d.

[0040] Specifically, a moving strip 202d is fixed on one side of the moving plate 201d, and a positioning frame 202e is fitted on the outside of the moving strip 202d. The positioning frame 202e and the moving strip 202d are movably connected, and the positioning frame 202e is fixed to the top of the support plate 202b.

[0041] When the movable plate 201d moves, it can drive the movable bar 202d to move. At this time, the movable bar 202d can move within the positioning frame 202e, which can support the movable plate 201d and prevent the movable plate 201d from shifting during movement.

[0042] Specifically, a first spring 202f is fixed to one end of the moving bar 202d, and the first spring 202f is fixed to the inner wall of the positioning frame 202e.

[0043] When the moving bar 202d moves to tighten the connecting clamp 201a, it can apply a squeezing force to the first spring 202f. After the squeezing of the moving plate 201d is released, the rebound force of the first spring 202f can drive the moving bar 202d back to its original position.

[0044] Specifically, the positioning component 300 also includes a movable part 302, which is disposed on the positioning strip 301b. A connecting box 302a is sleeved on the outside of the positioning strip 301b, and the connecting box 302a and the positioning strip 301b are movably connected.

[0045] A support frame is fixed to the bottom of the connecting box 302a. The support frame is fixed to the top of the support plate 202b and is sleeved on the outside of the positioning wheel 301a. It is rotatably connected to the positioning wheel 301a through a rotating shaft. The connecting box 302a can support the positioning strip 301b and prevent the positioning strip 301b from shifting.

[0046] Specifically, a positioning block 302b is sleeved on the outside of the pull rod 301c. The pull rod 301c and the positioning block 302b are movably connected. The positioning block 302b is fixed to one side of the connecting box 302a. A pull block 302c is fixed to one end of the pull rod 301c.

[0047] The positioning block 302b is used to support the pull rod 301c and prevent the pull rod 301c from shifting. The setting of the pull block 302c makes it convenient for the user to pull the pull rod 301c. By pulling the pull rod 301c, the positioning strip 301b can be separated from the positioning wheel 301a.

[0048] Example 3

[0049] Reference Figures 1-6 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0050] Specifically, a second spring 302d is fixed to one side of the positioning block 302b, and the second spring 302d is fixed to one end of the positioning strip 301b.

[0051] When the pull rod 301c is pulled to separate the positioning strip 301b from the positioning wheel 301a, a squeezing force can be applied to the second spring 302d. When the pull block 302c is released, the rebound force of the second spring 302d can drive the positioning strip 301b back to its original position and re-engage with the positioning wheel 301a.

[0052] Specifically, it also includes a main component 100, which is disposed on the connecting clamp 201a, including a bent pipe body 101 and a straight pipe 102. The bent pipe body 101 is disposed inside the connecting clamp 201a, and the straight pipe 102 is fixed to one side of the bent pipe body 101.

[0053] The bend body 101 is used to change the direction of the pipeline, so that the fluid can be smoothly transmitted between pipelines in different directions. The straight pipe 102 is fixed on one side of the bend body 101. Its function is to serve as the straight transmission part in the pipeline system, ensuring that the fluid is transported in a relatively stable direction. Together with the bend body 101, a complete pipeline transmission path is constructed.

[0054] Specifically, a sealing ring 103 is fixed inside the bent pipe body 101 and the straight pipe 102.

[0055] The sealing ring 103 is used to seal the pipeline. The sealing ring 103 can prevent the fluid transported in the pipeline from leaking, ensure that the fluid flows in the pipeline system along a predetermined path, and guarantee the sealing and safety of the pipeline system.

[0056] In use, other connecting pipes are placed inside the connecting clamp 201a, which engages with the bend body 101. Then, the positioning wheel 301a is rotated, which drives the cam 202a to rotate. The rotation of the cam 202a compresses the two moving plates 201d. When the cam 202a rotates and compresses the moving plates 201d, it applies a torsional force to the torsion spring 202c. The moving plates 201d drive the push rod 201c to move. The movement of the push rod 201c drives the push plate 201b to move. At this time, the movement of the push plate 201b can cause the two ends of the connecting clamp 201a to tighten inward, thereby fixing the bend body 101 with other connecting pipes.

[0057] When it is necessary to disconnect the connection of the bend body 101, the pull block 302c is pulled to move the pull rod 301c. When the pull rod 301c is pulled to separate the positioning strip 301b from the positioning wheel 301a, a squeezing force can be applied to the second spring 302d. The movement of the pull rod 301c can move the positioning strip 301b to separate from the positioning wheel 301a, thereby releasing the limitation on the positioning wheel 301a. At this time, the force of the torsion spring 202c can drive the cam 202a to rotate, thereby releasing the squeezing of the moving plate 201d. Then the moving plate 201d returns to its original position, causing the connecting clamp 201a to loosen, thereby separating the bend body 101 from other connecting pipes.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
