Description

Technical Field

[0001] The utility model relates to the technical field of pipeline protection, and more specifically, it relates to a gas pipeline protection structure. Background Art

[0002] A gas pipeline is a pipeline system specifically used to transport combustible gases (such as natural gas, liquefied petroleum gas, artificial gas, etc.). The design and construction of such pipelines need to consider the properties of the gas, the transportation distance, the usage scenario, and safety factors. Usually, flanges are provided at the ports of the pipelines, and the pipelines are connected by bolts passing through the flanges.

[0003] Over time, the flanges will be corroded, especially in environments with large temperature differences and frequent vibrations, resulting in unstable connections between gas pipelines and insufficient airtightness, leading to gas leakage.

[0004] Therefore, a protection structure is needed to ensure the connection stability and airtightness between gas pipelines. Summary of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a gas pipeline protection structure, which has the advantage of improving the connection stability of the pipe body and thus reducing the possibility of gas leakage.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a gas pipeline protection structure, including two pipe bodies with flanges fixedly connected to each other by bolts. A protection component is sleeved at the connection of the two pipe bodies. The protection component includes a left clamping plate and a right clamping plate that are rotatably connected to each other. The left clamping plate and the right clamping plate use the gravity of the pipe bodies to give the two pipe bodies a tendency to approach each other.

[0007] The utility model is further provided as follows: one end of the left clamping plate is fixedly connected with a first support plate, and one end of the right clamping plate is fixedly connected with a second support plate. The bottom surfaces of the first support plate and the second support plate form an angle, and the angle is between 90° and 180°.

[0008] The utility model is further provided as follows: the ends of the first support plate and the second support plate far from the left clamping plate and the right clamping plate are both fixedly connected with a contact plate, and the cross-section of the contact plate is arc-shaped.

[0009] The utility model is further provided as follows: elastic plates are arranged on the opposite end faces of the left clamping plate and the right clamping plate.

[0010] The utility model is further provided as follows: a plurality of through grooves for the bolts on the flange to pass through are provided on the left clamping plate, the right clamping plate, and the elastic plate.

[0011] The present utility model is further configured such that: the elastic plate is made of rubber, and the left clamping plate and the right clamping plate are both made of carbon structural steel.

[0012] To sum up, the present utility model has the following beneficial effects: through the setting of the protection component, the present utility model utilizes the gravity of the pipe body to transform it into a force that makes the two pipe bodies approach each other, thereby making the connection of the pipe bodies tighter. At the same time, the probability of the flange becoming loose over time is reduced, the risk of gas leakage in the pipeline is reduced, and the safety performance of the gas pipeline is improved. In addition, the left clamping plate and the right clamping plate made of carbon structural steel increase the durability of the present utility model. The design of the elastic plate reduces the frictional damage of the protection component to the flange and improves the service life. Description of the Drawings

[0014] Figure 2 is a structural schematic diagram of the protection component in the present utility model.

[0016] The present utility model will be described in detail below with reference to the drawings and embodiments.

[0017] Embodiment: A gas pipeline protection structure, as Figure 1 , Figure 2 shown, includes two pipe bodies 1 with flanges 11 fixedly connected to each other by bolts. A protection component 2 is sleeved at the connection of the two pipe bodies 1. The protection component 2 includes a left clamping plate 21 and a right clamping plate 22 that are rotatably connected to each other. The left clamping plate 21 and the right clamping plate 22 use the gravity of the pipe body 1 to give the two pipe bodies 1 a tendency to approach each other, so that even if the pipe body 1 expands due to heat or is in a place with frequent vibration, the connection of the flange 11 will not become loose and will always be clamped by the left clamping plate 21 and the right clamping plate 22 of the protection component 2 under the action of gravity. This not only makes the connection of the two pipe bodies 1 connected by the flange 11 tighter, but also prevents the flange 11 from being corroded and loosened under the action of environmental factors for a long time, affecting the connection stability.

[0018] As Figure 1 , Figure 2As shown in the figure, one end of the left clamping plate 21 is fixedly connected to a first support plate 212, and one end of the right clamping plate 22 is fixedly connected to a second support plate 222. The first support plate 212 and the second support plate 222 form an angle between 90° and 180°. The design of this structure enables the first support plate 212 and the second support plate 222 to better change the direction of force under the action of the gravity of the pipe body 1, and at the same time, it can also convert a greater force into the acting force of the left clamping plate 21 and the right clamping plate 22 on the flange 11. Both ends of the first support plate 212 and the second support plate 222 away from the left clamping plate 21 and the right clamping plate 22 are fixedly connected to a contact plate 23. The contact plate 23 is used to contact the ground. The cross-section of the contact plate 23 is arc-shaped to reduce the contact area between the contact plate 23 and the ground, thereby reducing the friction between the contact plate 23 and the ground and facilitating the sliding of the two contact plates 23 relative to the ground during the process of the left clamping plate 21 and the right clamping plate 22 clamping the flange 11.

[0019] As Figure 1 , Figure 2 shown in the figure, elastic plates 221 made of rubber are bonded to the opposite end faces of the left clamping plate 21 and the right clamping plate 22. The left clamping plate 21 and the right clamping plate 22 are both made of carbon structural steel. Through the setting of the elastic plates 221, it is avoided that the high-strength left clamping plate 21 and right clamping plate 22 made of carbon structural steel directly contact the flange 11, which causes greater wear to both the protection component 2 and the flange 11, and improves the durability of the protection component 2. A number of through grooves 211 for the bolts on the flange 11 to protrude are provided on the left clamping plate 21, the right clamping plate 22 and the elastic plates 221, so that the flange 11 connected by bolts will not affect the contact pressure of the left clamping plate 21 and the right clamping plate 22 on the flange 11. The structural design is simple and reasonable.

[0020] Working principle: After connecting two pipe bodies 1 with flanges 11 through bolts, place the protection component 2 on the ground, and place the part of the pipe body 1 with the flange 11 between the left clamping plate 21 and the right clamping plate 22 of the protection component 2. When the placement is completed, under the action of the gravity of the pipe body 1, the two contact plates 23 are driven to separate. When the two contact plates 23 separate from each other, they will drive the left clamping plate 21 and the right clamping plate 22 to squeeze the flanges 11 on the two pipe bodies 1 located between them, giving the two pipe bodies 1 a tendency to approach each other. Under the buffering action of the elastic plates 221, the wear between the flange 11 and the left clamping plate 21 and the right clamping plate 22 is reduced, and the durability of the protection component 2 is improved. Through the setting of the protection component 2 of the present utility model, it is prevented that the pipe bodies 1 connected through the flanges 11 become loose in an environment with temperature changes or frequent vibrations, resulting in gas leakage, improving the airtightness of the pipe bodies 1 and protecting the tightness of the connection of the pipe bodies 1.

All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements should also be regarded as within the protection scope of the present utility model.
