Summary of the invention
The utility model connects the problem easily transmitting nuisance vibration for existing rigid conduit, provide a kind of a kind of vibration damping device for pipe joint that can effectively solve the problem.
A kind of vibration damping device for pipe joint of the present utility model is by the following technical solutions:
A kind of vibration damping device for pipe joint, mainly comprise pipeline, seal ring, fluid weakening cylinder and rubber stopper, pipeline is divided into pipeline A and pipeline B, seal ring to be divided into seal ring A and seal ring B, installs seal ring A, seal ring B, fluid weakening cylinder and rubber stopper successively from inside to outside between pipeline A and pipeline B; The diameter of described pipeline A jointing pipeline section is greater than other pipeline sections, and pipeline A jointing has a profound circular groove and is provided with internal thread on its side, and pipeline B interface place has two circular grooves, and two circular grooves are other to be had a profound circular groove and is provided with outside thread on its side; Described seal ring A and seal ring B is " O " shape structure, and seal ring A and seal ring B is arranged in two circular grooves at pipeline B interface place respectively; Described fluid weakening cylinder is made up of rubber bag tank and high-viscosity fluid, and rubber bag tank is long tubular construction, is made up of viscoelasticity high-damping rubber material, and rubber bag tank is arranged in the profound circular groove in pipeline A and pipeline B, and high-viscosity fluid is glycerine; Described rubber stopper is middle part open-celled structure, and is provided with internal thread in middle vacancy, is provided with outside thread outside rubber stopper, and rubber stopper selects viscoelasticity high-damping rubber material, and rubber stopper is pressed on sealing gasket, and passes through its internal and external screw thread and be connected with pipeline B and pipeline A respectively.
The utility model adopts double-sealing and seal ring A and seal ring B in the joint of pipeline A and pipeline B, realizes strengthening seal for pipe joints by this design, prevents single seal ring lost efficacy and caused leakage accident.
The rubber bag tank of the utility model in fluid weakening cylinder adopts viscoelasticity high-damping rubber material, its inner fluid adopts high-viscosity fluid glycerine, the absorption of vibrational energy and separating vibration energy is realized to connected tube transmission by this design, specific works process is as follows: as when pipeline A vibrates, vibrational energy will be delivered to rubber bag tank, by the local deformation of rubber bag tank, kinetic energy is converted to potential energy, in addition being converted to heat energy by rubbing in the viscosity between its rubber molecular chain by kinetic energy, consuming vibrational energy by above two kinds of modes; And fluid adopts high-viscosity fluid glycerine, its high viscosity can be utilized, the kinetic energy of transmission is converted to heat energy.The effect in sum, during work, by rubber bag tank and high-viscosity fluid by the vibration energy absorption of pipeline A, thus play separating vibration energy and transmit to pipeline B, buffering pipe A vibrates, preventing pipeline B from vibrating.
Rubber stopper is adopted viscoelasticity high-damping rubber material by the utility model, plays absorbing vibrational energy equally, the effect of isolation connected tube vibration.
The beneficial effects of the utility model are: realize strengthening seal for pipe joints by double-sealing design, prevent single seal ring to lose efficacy and cause leakage; Realize vibration energy absorption by fluid weakening cylinder and rubber stopper, and separating vibration energy is to connected tube transmission.
