Description

Technical Field

[0001] This utility model relates to the field of pipeline valve maintenance technology, and in particular to a device for replacing intermediate valves in vertical pipelines. Background Technology

[0002] Valves, as important pipeline accessories, are mainly used to open and close pipelines, control flow direction, and regulate and control the parameters of the transported medium. In actual use, due to prolonged operation, valves inevitably suffer damage, leading to a decline in their sealing performance. Therefore, when valves or sealing components are damaged, they must be replaced promptly.

[0003] In on-site operations, replacing valves in the middle of vertical pipelines presents numerous challenges. When removing a valve, it's difficult to effectively secure the pipelines above and below it, easily leading to issues like pipeline eccentricity and settlement. Furthermore, during the reinstallation of the new valve, sufficient space must be maintained between the upper and lower pipelines to allow for timely adjustment of the valve's alignment and to compensate for any issues caused by pipeline settlement preventing proper valve placement. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a vertical pipeline intermediate valve replacement device, which solves the problems in the prior art where pipelines are prone to eccentricity and settlement, and new valves are difficult to reinstall when replacing intermediate valves in vertical pipelines.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A vertical pipeline intermediate valve replacement device includes an upper pipeline and a lower pipeline. The upper part of the upper pipeline flange is provided with two first clamping plates that are interlocked with each other and connected by a first clamping bolt. The lower part of the lower pipeline flange is provided with two second clamping plates that are interlocked with each other and connected by a second clamping bolt. An adjusting bolt is fixedly installed above the support part of the second clamping plate. After the adjusting nut is installed on the adjusting bolt, the adjusting part of the first clamping plate is movably sleeved on the adjusting bolt.

[0007] The first clamp is a right-angle clamp, and the second clamp is an arc-shaped clamp, with the inner circle of the second clamp matching the outer circle of the lower pipe.

[0008] The outer side of the first clamping plate is detachably equipped with multiple fixing buckles. The fixing buckles are L-shaped, with the long side of the fixing buckle detachably connected to the outer side of the first clamping plate and the short side of the fixing buckle supporting the bottom surface of the upper pipe flange.

[0009] Compared with the prior art, the beneficial effects of this utility model are: by fixing the upper and lower pipes with the first and second clamping plates respectively, and with the help of adjusting bolts and nuts, the position of the pipes can be precisely adjusted, effectively eliminating errors caused by settlement or deviation, creating good conditions for the installation of new valves, and improving the accuracy and efficiency of installation.

[0010] The system uses a matching clamp plate. The right-angled first clamp plate fits the upper pipe flange, while the arc-shaped second clamp plate fits the outer circle of the lower pipe, increasing the contact area. In addition, the L-shaped fixing buckle further reinforces the upper pipe, greatly enhancing the pipe fixing effect and reducing the risk of pipe displacement.

[0011] Stable pipe fixing reduces the possibility of gasket damage due to pipe instability, thus lowering maintenance costs; at the same time, it avoids injury to workers caused by pipe movement, ensuring personnel safety. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0018] A vertical pipeline intermediate valve replacement device includes an upper pipeline 1 and a lower pipeline 2. The upper flange of the upper pipeline 1 has two interlocking first clamping plates 3 connected by a first clamping bolt 4. The lower flange of the lower pipeline 2 has two interlocking second clamping plates 5 connected by a second clamping bolt 7. An adjusting bolt 8 is fixedly installed above the support part 6 of the second clamping plate 5. After an adjusting nut 9 is installed on the adjusting bolt 8, the adjusting part 10 of the first clamping plate 3 is movably sleeved on the adjusting bolt 8. By rotating the adjusting nut 9, the height of the first clamping plate 3 can be precisely adjusted, thereby adjusting the positional relationship between the upper and lower pipelines, effectively eliminating errors caused by pipeline settlement or deviation, and creating favorable conditions for the smooth installation of the new valve 12.

[0019] The first clamping plate 3 is a right-angle clamping plate, and the second clamping plate 5 is an arc-shaped clamping plate. The inner circle of the second clamping plate 5 is adapted to the outer circle of the lower pipe 2. The right-angle first clamping plate 3 can better match the structure of the flange of the upper pipe 1, providing a stable fixing effect; the arc-shaped design of the second clamping plate 5, which is adapted to the outer circle of the lower pipe 2, can increase the contact area between the clamping plate and the pipe, and improve the reliability of fixing.

[0020] Multiple fixing buckles 11 are detachably installed on the outer side of the first clamping plate 3. The fixing buckles 11 are L-shaped, with their long sides detachably connected to the outer side of the first clamping plate 3 and their short sides supporting the bottom surface of the flange of the upper pipe 1. This setting of fixing buckles 11 further enhances the fixing effect on the upper pipe 1, ensuring the stability of the upper pipe 1 during valve 12 replacement and reducing the possibility of pipe displacement.

[0021] When using:

[0022] First, the two first clamping plates 3 are snapped onto the upper part of the flange of the upper pipe 1, and the two first clamping plates 3 are securely connected by the first clamping bolts 4, ensuring that the first clamping plates 3 are firmly installed on the upper pipe 1. Then, the two second clamping plates 5 are snapped onto the lower part of the flange of the lower pipe 2, and the second clamping plates 5 are fixed to the lower pipe 2 using the second clamping bolts 7. Next, an adjusting bolt 8 is installed above the support part 6 of the second clamping plate 5, and an adjusting nut 9 is screwed into the adjusting bolt 8. Then, the adjusting part 10 of the first clamping plate 3 is movably fitted onto the adjusting bolt 8. Based on the actual positional deviation between the upper and lower pipes, the height of the first clamping plate 3 on the adjusting bolt 8 is adjusted by rotating the adjusting nut 9, thereby fine-tuning the positional relationship between the upper and lower pipes, keeping the upper and lower pipes aligned, and eliminating errors caused by settlement or deviation.

[0023] After the pipe position adjustment is completed, multiple L-shaped fixing buckles 11 are installed on the outside of the first clamping plate 3, so that the long side of the fixing buckle 11 is connected to the outside of the first clamping plate 3 by a detachable method such as bolts, and the short side of the fixing buckle 11 is supported on the bottom surface of the flange of the upper pipe 1, further enhancing the fixing effect on the upper pipe 1.

[0024] At this point, the damaged valve 12 can be removed from the middle of the vertical pipe, and a new valve 12 can be installed. During the installation of the new valve 12, the pipe position can be finely adjusted again by adjusting the adjusting nut 9 to ensure that the new valve 12 can be accurately installed between the upper and lower pipes and to ensure a good seal.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
