Abstract
The invention discloses a double-layer vibration damper with a temperature varying pipeline capable of stretching freely, which belongs to the technical field of vibration damping and comprises a vibration damping bracket used for supporting a pipeline. The vibration damping bracket is fixed on a panel under the vibration damping bracket through symmetrically installed vibration damping bracket supports, and a spring absorber is installed under a panel. The spring absorber comprises a vibration damping spring, a spring vibration damping base plate, a rolling steel ball and a base support. One end of the vibration damping spring is installed on the lower end face of the panel, the other end of the vibration damping spring is installed on the spring vibration damping base plate, and the spring vibration damping base plate is installed on the base support through the rolling steel ball and is capable of rolling on the base support. The double-layer vibration damper enables a pipeline to be arranged in the support of the double-layer vibration damper, moves with the change of the axial size and the radial size of the pipeline and maintains the position of a damping system in the pipeline. The double-layer vibration damper has the advantages of being capable of enabling multiple-dimension size change of the pipeline in the vibration state caused by temperature change to be removed through the rolling steel ball under the double-layer damping system and simple in structure.
Description
Affiliated technical field
The present invention relates to the double-deck vibration damping equipment that a kind of alternating temperature pipeline freely stretches, belong to antivibration area, especially can adapt to the multidimensional dimensional changes that steam pipework expands with heat and contract with cold.
Background technique
Pipe vibration is to cause under the effect of its internal fluid pressure and flow velocity, and pipeline is if receiving vibration for a long time can produce fatigue ruption, especially at stress raiser; Fatigue ruption can so that generator tube thread breakage, medium leak, cause serious production accident, at present; The measure and the method that solve pipe vibration have multiple; One type is damping or the change system stiffness through the change system, to change system frequency, reaches the purpose of weakening.One type for reaching the result who eliminates airstream vibration through fluctuation pressure or the adjustment gas column natural frequency that changes air-flow.In these vibration reducing measures, through to reach the measure application of the construct noise between reducing pipeline and supporting more extensive adding flexible apparatus-rubber damping carriage below the vibrating conduit.In general, the vibration damping bracket housing is a hard, wear-resistant rubber, and it is low to have the natural frequency of vibration, the characteristics that damping ratio is big.Product structure is simple and reliable, easy for installation simultaneously, is applicable to the vibration and noise reducing of all kinds of aerial pipelines.The noise transfer of eliminating pipe-line system etc. all there is remarkable result, has further rooted out the influence of overhead speaker construction.But; After pipeline being carried out the vibration damping processing; Whole pipe radially is being in free state, particularly has the pipeline of cold and hot alternating temperature, axially, radially all possibly produce deformation displacement; If cause the vibration damping bracket pressurized uneven and cause effectiveness in vibration suppression to descend because the size of pipeline or position change, even do not have damping effect.
Summary of the invention
In order to overcome owing to the pipeline axial that temperature variation causes, size or change in displacement radially; The deficiency that existing rubber damping carriage can not move freely; The double-deck vibration damping equipment that the present invention provides a kind of alternating temperature pipeline freely to stretch can adapt to the multidimensional dimensional changes that steam pipework expands with heat and contract with cold.
The technical solution adopted for the present invention to solve the technical problems is: the double-deck vibration damping equipment that a kind of alternating temperature pipeline freely stretches; Comprise the vibration damping bracket that is used to hold pipeline; The vibration damping bracket that vibration damping bracket is installed through symmetry is supported and fixed on the flat board that is positioned at below the vibration damping bracket; Spring cushion is installed below flat board, and described spring cushion comprises shock-absorbing spring, spring damping base plate, rolling steel balls and base support; One end of described shock-absorbing spring is contained on the dull and stereotyped lower end surface, and the other end is contained on the spring damping base plate, and described spring damping base plate is installed on the base support through rolling steel balls and can on base support, rolls.
Owing to adopted technique scheme; Promptly below the rubber damping carriage of pipeline, increase by a sleeve spring vibration damper; Pipeline is in the support of double-deck vibration damping, guarantees effectiveness in vibration suppression, simultaneously; Under the stand of spring cushion, settle the rolling steel balls that to roll; And steel ball can move along with the variation of pipeline axial, radial dimension, remain on the steel ball spring cushion and rubber damping carriage pipeline position of center line, guarantee that the pressure of pipeline is evenly distributed on the platform of whole vibration damping bracket and spring cushion; All the time make above double-deck vibration insulating system be in good working order, reach and satisfy the pipeline multidimensional dimensional changes of bringing owing to temperature variation.
The invention has the beneficial effects as follows that the multidimensional dimensional changes that the pipeline that is in vibrational state is caused in temperature variation is eliminated through the rolling steel balls below the double-deck vibration insulating system, and simple in structure.
