Description

Technical Field

[0001] The utility model relates to the technical field of pipelines, in particular to a variable-diameter gas pipeline component. Background Art

[0002] Natural gas has been widely used as an energy source in people's daily lives. People use gas pipelines to transport natural gas to designated areas and then transport it to every household. Under normal circumstances, the diameter of the gas pipeline in a high-rise residential building decreases from bottom to top, and the upper and lower pipelines are coaxial and in a vertical state.

[0003] This type of variable diameter pipe is generally fixed to the wall through a pipe clamp bracket. One end of the pipe clamp bracket clamps the pipe and the other end is fixed to the wall through an expansion bolt, thereby tightening and fixing the pipe. Since the pipe diameter decreases step by step from bottom to top, the distance between each section of the pipe and the wall is different. This will result in the depth of the expansion bolt driven into the wall cannot be accurately controlled when each section of the pipe is fixed with a pipe clamp bracket. If the depth of the expansion bolt driven into the wall is too large, on the one hand, the wall will be damaged, and on the other hand, the pipe will be tilted due to the pulling of the pipe clamp bracket, affecting the construction quality of the gas pipeline.

[0031] Reference Figure 1-5A variable diameter gas pipeline component is used for connecting and fixing variable diameter gas pipelines, in order to facilitate the connection of multiple sections of gas pipelines with different diameters and stably fix them on the wall.

[0032] The variable-diameter gas pipeline assembly comprises a gas pipeline and a fixing mechanism;

[0033] The gas pipeline includes a plurality of pipe sections 1 and a plurality of pipe joints 2. The diameter of each pipe section 1 decreases step by step from bottom to top. Each pipe joint 2 is fixedly connected between two adjacent pipe sections 1, so that the plurality of pipe sections 1 are connected end to end. Each pipe joint 2 includes a reducing portion 201, a lower straight section 202 and an upper straight section 204. The reducing portion 201 is arranged between the lower straight section 202 and the upper straight section 204. The diameter of the lower straight section 202 is the same as the diameter of the pipe section 1 at the bottom of the pipe joint 2, so that the pipe joint 2 is connected to the bottom pipe section 1. The upper straight section 204 is straight. The diameter of the pipe joint 2 is the same as the diameter of the pipe section 1 at the top of the pipe joint 2, so that the pipe joint 2 is convenient to communicate with the top pipe section 1, and one side of the reducing portion 201 in the pipe joint 2 is streamlined to smoothly connect the lower straight section 202 and the upper straight section 204, and the other side of the pipe joint 2 is vertical, so that after the pipe joint 2 is connected to the top and bottom pipe sections 1, one side of each pipe section 1 and each pipe joint 2 remains vertical, so that the distance between one side of each pipe section 1 and each pipe joint 2 and the wall is equal, which facilitates the fixing mechanism to fix the connected gas pipeline on the wall.

[0034] Each fixing mechanism 3 includes a first clamping plate 301, a second clamping plate 302 and two third clamping plates 303. The first clamping plate 301 and the second clamping plate 302 are located on both sides of the lower straight section 202 and can clamp the pipe joint 2. One end of the first clamping plate 301 is fixedly connected with an expansion bolt 4, so that it is convenient to fix the first clamping plate 301 on the wall. Since the side of each pipe segment 1 and each pipe joint 2 close to the wall is at an equal distance from the wall, the first clamping plate 301 in each fixing mechanism 3 is at an equal distance from the wall, so that pipe segments 1 with different cross-sectional diameters can be fixed to the wall through fixing mechanisms 3 of the same specifications.

[0035] Two connecting members are provided between the first clamping plate 301 and the second clamping plate 302. The two connecting members are provided on both sides of the pipe joint 2. Each connecting member includes a bolt 5, two threaded sleeves 6 and two connecting rods 7. The two threaded sleeves 6 are threadedly connected to the outside of the bolt 5. One end of the two connecting rods 7 is rotatably connected to one end of the first clamping plate 301 and the second clamping plate 302 respectively, and the other end is rotatably connected to the two threaded sleeves 6 respectively. By rotating the bolt 5, the threaded sleeves 6 can be moved outside the bolt 5, so that the first clamping plate 301 and the second clamping plate 302 are driven to approach or move away through the connecting rod 7, so that the first clamping plate 301 and the second clamping plate 302 can clamp and fix the lower straight sections 202 of different diameters. Each third clamping plate 303 is pressed and fixed on the outer wall of the pipe joint 2 by a bolt 5. The rotation of the bolt 5 causes the first clamping plate 301 to move. When the second clamping plate 302 clamps and fixes the lower straight section 202, the bolt 5 will also make the two third clamping plates 303 approach each other, thereby clamping and fixing the lower straight section 202 in the other two directions, thereby improving the stability of pipe clamping and fixing, and because the outer wall of the pipe joint 2 is provided with a plurality of clamping blocks 203, the first clamping plate 301 and the second clamping plate 302 are provided with a clamping groove on the inner side, and each clamping block 203 is adapted to a clamping groove, so that when the first clamping plate 301 and the second clamping plate 302 are clamped and fixed, they play a role of positioning and limiting, thereby preventing the lower straight section 202 from moving under clamping, and the first clamping plate 301, the second clamping plate 302 and the third clamping plate 303 are all arc-shaped, thereby increasing the contact area with the lower straight section 202, and a rubber pad is provided on the inner side to prevent the lower straight section 202 from being damaged by the clamping force.

[0036] The working principle of the variable diameter gas pipeline assembly is as follows: first, the first clamping plate 301 is fixed to the wall by the expansion bolt 4, and then the pipe sections 1 of different diameters are connected one by one along the diameter size through the pipe joint 2 to form a gas pipeline. Since one side of the pipe joint 2 is vertical, the distance between one side of the connected gas pipeline and the wall is equal everywhere. Then, the vertical side of the gas pipeline is made close to the first clamping plate 301, which can ensure that the axis of the pipe section 1 is vertical and close to each first clamping plate 301. Then, the bolt 5 is passed through the two threaded sleeves 6, and the bolt 5 is rotated to make the threaded sleeve 6 move outside the bolt 5, so that the first clamping plate 301 and the second clamping plate 302 are mutually fixed. When the first and second clamping plates 301 and 302 are brought closer, the pipe connector 2 is clamped and fixed. At the same time, the bolt 5 pushes the two third clamping plates 303 to press on the pipe connector 2, so that the two third clamping plates 303 clamp and fix the pipe connector 2 in another direction, and cooperate with the first clamping plate 301 and the second clamping plate 302 to achieve stable fixation of the pipe connector 2. When the first clamping plate 301 and the second clamping plate 302 clamp and fix the pipe connector 2, the block 203 on the outer wall of the pipe connector 2 is clamped into the groove of the first clamping plate 301 and the second clamping plate 302, so that the pipe connector 2 cannot move on the first clamping plate 301 and the second clamping plate 302, thereby improving the stability of the pipe fixation.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
