Abstract
Description
Technical Field
[0001] This utility model relates to the field of heating pipeline technology, specifically a protective device for heating engineering pipelines. Background Technology
[0002] In heating projects, pipeline systems bear the critical responsibility of heat energy transmission, and pipeline connections, as the weakest link in the entire system, directly affect heating efficiency and safety. Currently, most heating pipeline connections only use conventional sealing and fixing methods, such as flange connections and external insulation layers after welding, lacking targeted protective measures. When heating pipelines cross complex environments such as roads and buildings, they are highly susceptible to external forces such as vehicle traffic, foundation settlement, and collisions with construction machinery. These impacts can cause wear at pipeline connections, leading to aging and damage of sealing materials, loosening of connecting parts, and ultimately, problems such as heat leakage and pipeline disconnection.
[0003] To address this issue, we propose a protective device for heating projects that cross pipelines. Utility Model Content
[0004] The purpose of this utility model is to provide a protective device for pipelines passing through heating projects, which solves the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a protective device for pipelines passing through heating projects, comprising two pipeline bodies, with their end faces in contact with each other, and the two pipeline bodies installed together by a flange assembly, wherein a buffer assembly is installed between the inner wall of one of the flanges and the outer wall of the pipeline body, and a shock-absorbing assembly is installed between the inner walls of the two pipeline bodies.
[0006] Preferably, there are two buffer assemblies, with the other buffer assembly installed between another flange and another pipe body.
[0007] Preferably, the pipe body includes an inner layer, the inner wall of which is fixedly fitted with a heat insulation layer, the outer wall of which is fixedly fitted with a shock-resistant layer, and the outer wall of which is fixedly fitted with an outer layer. The heat insulation layer can prevent heat loss, and the shock-resistant layer can enhance the shock resistance of the pipe body.
[0008] Preferably, the buffer assembly includes a buffer pad, which is cylindrical in shape and has eight perforations on its surface. The eight perforations are arranged in a circular array. The buffer pad can provide a buffering effect, disperse collision energy, and reduce the force of injury. The perforations can enhance the buffering capacity.
[0009] Preferably, the inner wall of the hollow hole is fixedly installed with a first arc-shaped buffer rubber sheet and a second arc-shaped buffer rubber sheet of the same size and shape. The buffering capacity can be enhanced by setting the first arc-shaped buffer rubber sheet and the second arc-shaped buffer rubber sheet.
[0010] Preferably, the vibration damping assembly includes a first vibration damping pad, which is columnar in shape. The outer wall of the first vibration damping pad is fixedly installed to the inner wall of the pipe body. A second vibration damping pad, which is T-shaped, is sleeved on the inner wall of the first vibration damping pad. The outer wall of the end of the second vibration damping pad is fixedly installed to the inner wall of another pipe body. The installed first and second vibration damping pads can achieve a vibration damping effect, reduce the vibration amplitude, and reduce the wear force between the two pipe bodies.
[0011] This utility model provides a protective device for pipelines crossing heating projects. This protective device for pipelines crossing heating projects has the following beneficial effects:
[0012] (1) The protective device for the pipeline crossing the heating project can play a buffering role by setting a buffer pad, which can disperse the collision energy and reduce the damage force. The buffering capacity can be enhanced by setting a hollow hole and installing a first arc-shaped buffer rubber sheet and a second arc-shaped buffer rubber sheet in the hollow hole.
