Abstract

The invention relates to a vibration isolation mechanism for effectively protecting a pipeline system when an earthquake occurs. The vibration isolation mechanism with a displacement compensation expansion effect is formed by connecting three flexible groove collar clamp members with displacement compensation actions in series through two sections of pipelines, and further the functions of pipeline vibration isolation, noise elimination and noise reduction are realized.

Description

A kind of vibration isolating mechanism

Patent of the present invention relates to a kind of angular displacement and linear displacement characteristic of utilizing single flexible groove clamping hoop spare to have, is combined to form a series of flexible groove clamping hoop spare to realize the vibration isolating mechanism of the advantage of independent flexible groove clamping hoop spare angular displacement and linear displacement extension effect.This vibration isolating mechanism forms a device that is similar to the conventional metals soft connector by the tandem arrangement of three flexible groove clamping hoop spares, can carry out a certain amount of angular displacement and linear displacement compensation to pipeline.Because flexible groove clamping hoop spare itself has rubber gasket, packing ring has the effect of a certain amount of absorption noise and vibration, so this vibration isolating mechanism also has the effect of certain noise elimination noise reduction when having the bit shift compensation function.

At present; owing to inquire into not enough to research and relevant protective measure that pipe-line system is destroyed; the general both at home and abroad pipe-line system that laterally or vertically is provided with in the localized metallic FlexbleJoint protection taphrogeny that adopts; but because that no matter impurity such as the as easy as rolling off a log deposition dirt of transverse metal FlexbleJoint make in system maintenance or pipe vibration compensation and isolation effect is all not good; and metal corrugation compensator is limited for the adaptability of taphrogeny; very easily be torn when running into the bigger earthquake of earthquake intensity; and As time goes on, metal corrugation compensator is easy to deform and makes that descending appearred in the compensation ability of pipeline when earthquake took place.Because taphrogeny has the shortage that protection is studied to pipe-line system in more difficult foreseeability and the earthquake; make the pipe-line system that should need in a large number to implement the antidetonation protective measure not be effectively protected; in case taphrogeny takes place; pipe-line system will may cause because of being effectively protected the pipe-line system autoclasia (as leak, stress crosses the ambassador joint and breaks etc.) time, and might bring relevant secondary disaster.Pipe-line system when earthquake takes place makes the afunction of its original piping design or part lose because destroy, this will cause heavy losses to the security of the lives and property.Destruction as the pulverized coal in power plant conveyance conduit will cause the power station by forced-stopping machine; the destruction of heat supply pipeline will cause large area region to lose the supply of heating installation in cold season, and the destruction of fire protection pipeline will make that the fire of often following earthquake and causing can't be controlled etc.The protection of pipe-line system has important meaning in fields such as commerce, industry when therefore earthquake being taken place, and the frequent area of geological movement is seemed particularly important.

In order to tackle the destruction of seismic activity to pipe-line system; this vibration isolating mechanism will provide the pipe-line system protection of pipe-line system in certain intensity of earthquake scope; in the time of protection pipe-line system and relevant main equipment, drop to minimum level destroying the secondary disaster of bringing because of pipe-line system.

The technological scheme that patent of the present invention adopted is: the characteristics of utilizing the multiple flexible groove clamping hoop spare tandem arrangement of vibration isolating mechanism, the flexible groove clamping hoop spare wigner effect function extension that originally has certain angular displacement and linear displacement function, the isolation of pipe vibration in effective bit shift compensation when realizing the pipeline taphrogeny and the earthquake alleviates because the destruction that taphrogeny causes pipe-line system.

Further set forth below in conjunction with 1 pair of this vibration isolating mechanism of accompanying drawing.

Description of drawings

Accompanying drawing 1 vibration isolating mechanism plan view

(1) number among the figure, (2) number, (3) number are flexible groove clamping hoop spare; (I) number, (II) number plays the pipeline of interconnect function for intermediate section.

As shown in Figure 1, this vibration isolating mechanism mechanism is linked together by the pipeline that (I) number, (II) number intermediate section play interconnect function by (1) that itself has a certain amount of angular displacement and linear displacement number, (2) number, (3) number flexible groove clamping hoop spare respectively, forms one and has the mechanism of bit shift compensation effect significantly.

This vibration isolating mechanism utilizes three flexible groove clamping hoop spare tandem arrangement that originally have a certain amount of angular displacement and linear displacement, has the effect of certain noise elimination noise reduction when realizing the pipe vibration buffer action.This vibration isolating mechanism has rational in infrastructure, need not to take big quantity space, is easy to advantages such as on-the-spot installation and later maintenance, can be widely used in the antidetonation protection of pipe-line systems such as commerce, industry.

Claims

1. this vibration isolating mechanism is connected in series by two segment pipes by three flexible groove clamping hoop spares that have certain angular displacement and a linear displacement compensating action itself and forms.

2. vibration isolating mechanism according to claim 1, three flexible groove clamping hoop spare features are made up of bolt, nut, rubber gasket and mechanical cover.
