Description

Technical Field

[0001] The utility model belongs to the technical field of pipelines, in particular to an impact-resistant PVDF pipeline structure. Background Art

[0002] PVDF pipe is a pipe made of polyvinylidene fluoride material. Polyvinylidene fluoride is a polymer aggregate. When it is heated to 500℃ or above, it will melt and be bonded into one body after being connected under the action of external force. After cooling and forming, the pipe itself will continue to have super tensile strength, breaking elongation and other properties. In addition, PVDF pipe also has excellent chemical resistance and is not corroded by acids, alkalis, strong oxidants, and halogens at room temperature. PVDF pipe plays an important role in many fields with its excellent performance.

[0003] During the use of traditional PVDF pipes, the pipe wall is easily damaged by the fluid flowing too fast in the pipe under the impact of the flow of the fluid in the pipe. The main reason for the damage is that the pipe wall is easily deformed when the fluid in the pipe moves, which will damage the PVDF pipe over time. Utility Model Content

A rotating rod is rotatably connected to the side of the fixed block close to the pipeline body, and a sleeve plate is movably sleeved on the outer side of the rotating rod. An installation groove is provided on the side of the sleeve plate away from the fixed block.

Buffer springs are fixedly connected between the two movable blocks and the fixed block, and both buffer springs are sleeved on the outer side of the annular rod.

[0008] Preferably, the outer side of the sleeve plate is symmetrically rotatably connected to two movable rods, and one end of the two movable rods away from the sleeve plate is rotatably connected to the two movable blocks respectively.

[0009] Preferably, the mounting mechanism includes two side plates symmetrically located on the outside of the annular plate, a connecting plate fixedly connected between the two side plates and the annular plate, an L-shaped round rod fixedly connected between the connecting plate and the side plate, a slide plate movably sleeved on the outside of the L-shaped round rod, a clamping plate is provided on the side of the slide plate away from the connecting plate, the clamping plate is fitted with the outer wall of the pipe body, a U-shaped round rod is fixedly installed on the side of the clamping plate close to the slide plate, and the slide plate is fixedly sleeved on the outside of the U-shaped round rod.

[0010] Preferably, a return spring is fixedly connected between the slide plate and the connecting plate, and the return spring is sleeved on the outer side of the L-shaped round rod.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] (1) The utility model, through the cooperation between the rubber ball and the sleeve plate, and the rotating rod and the fixed block, makes the sleeve plate move when the pipe body is impacted, and through the cooperation between the movable rod and the movable block, and the annular rod and the buffer spring, makes the buffer spring deform, and absorbs part of the impact force under the action of the buffer spring elasticity, and then can buffer the pipe body, thereby improving the impact resistance of the pipe body and avoiding damage to it;

[0013] (2) The new type facilitates the movement of the two clamps through the cooperation between the slide plate and the U-shaped round rod, and the L-shaped round rod and the clamp. Then, under the action of the elastic force of the return spring, the clamps can be tightly fitted with the pipe body, making it easier for the two clamps to clamp the pipe body, thereby facilitating the installation of the annular plate on the outside of the pipe body.
