Abstract
The utility model relates to a novel expansion joint which has relatively large displacement compensation capability and can perform displacement compensation in axial direction, transverse direction and angular direction. The novel expansion joint is fixedly connected between a left connecting pipe and a right connecting pipe. Two ends of the expansion joint are respectively connected with the left connecting pipe and the right connecting pipe through a bolt, a nut and a gasket; wherein the bolt, the nut and the gasket are arranged outside each connecting pipe. Convenient operation is realized. The expansion joint body is made of rubber and is provided with three crest-shaped projections. A middle crest-shaped projection is also provided with a metal reinforcing ring, thereby greatly improving compression resistance of the novel expansion joint. The novel expansion joint has the advantages of: simple structure, low cost, high elasticity, high compression resistance, high displacement amount, high abrasion-absorbing and noise-reducing effect, and long service life.
Description
Technical field
The utility model relates to a kind of expansion joint, particularly a kind of non-metal expansion joint.
Background technique
Expansion joint is the additional stress that compensation causes because of temperature difference and mechanical vibration, and is arranged on a kind of flexible structure on container shell or pipeline.Because it is as a kind of elastic compensating element that can free-extension, the advantages such as reliable operation, functional, compact structure, have been widely used in the departments such as chemical industry, metallurgy, nuclear energy.Expansion joint is also slip joint traditionally, or corrugated expansion joint, be to utilize effective dilatation of the elastic element of corrugated expansion joint to absorb pipeline, conduit or the container a kind of compensation device by former thereby the dimensional changes that produces such as expand with heat and contract with cold, belong to a kind of compensating element.Expansion joint can be to axially, laterally and the absorption of angular displacement, for pipeline, equipment and system add thermal walking, mechanical displacement absorbs vibration, reduces noise etc.Non-metal expansion joint can compensating axial, laterally, the product such as angle, have without thrust, simplify the features such as susceptor design, corrosion-resistant, high temperature resistant, silencing vibration-damping, be specially adapted to hot air duct and fume ducts.Use at present the expansion joint in industrial system, generally adopt metallic sheath cartridge type structure, by inside and outside sleeve, formed, between inside and outside sleeve, pass through seal with O ring, structure heaviness, displacement amount is little, and cost is high.
The utility model will overcome existing expansion joint structure heaviness exactly, and displacement amount is little, and the deficiency that cost is high provides one can compensate multiple directions, is greatly better than Pipelines with Single Direction Compensation.In pipeline connection procedure, the appearance of systematic error is unavoidable, so non-metal compensator has compensated alignment error preferably.Scrap metal material in non-metal compensator itself has the function of sound absorption, vibration isolation, can effectively reduce the noise and vibration of the systems such as boiler, blower fan and certain antiseptic power.Simple in structure, body is light, manufacture, easy to maintenance, cost is low, long service life.
Model utility content
The technical problems to be solved in the utility model is: a kind of novel expansion joint is provided, have compared with large displacement compensation capability, can carry out the compensation of axial, horizontal and angular displacement, this expansion joint is fixedly connected between left adapter and right adapter, with bolt and nut and pad, couple together respectively, be arranged on the outside of adapter, easy to operate, the material of this expansion joint body is rubber, on body, there are three ripple peak-like convexes, at middle crest shape high spot, also have metal stiffening ring, increased greatly the withstand voltage properties of this expansion joint.This model utility is simple in structure, and cost is low, good springiness, withstand voltage height, displacement amount are large, and vibration-absorbing denoising is effective, long service life.
In order to address the above problem, the utility model is realized by following technology,
A novel expansion joint, comprises bolt, metallic shim, nut, left adapter, expansion joint, metal stiffening ring, right adapter.Expansion joint one end is connected with left adapter, fastening with bolt, nut, pad; One end is connected with right adapter, fastening with bolt, nut, pad.On expansion joint, there are three ripple peak-like convexes, at middle crest shape high spot, also have metal stiffening ring, increase withstand voltage properties, bulk material is rubber, have compared with large displacement compensation capability, can carry out the compensation of axial, horizontal and angular displacement, have the noise of reduction, reduce vibrations and certain antiseptic power.
Expansion joint is arranged on the outside of left and right adapter, installs and changes easily, good sealing effect.
Expansion joint is arranged on vertical pipe, prevents that flange from bearing water corrosion.
Expansion joint two ends tighten together with two pipe nipples with bolt, nut, pad respectively, seal good, compact structure.
Three ripple peak-like convexes are set on expansion joint, at middle crest shape high spot, metal stiffening ring are set, stiffening ring increases the withstand voltage properties of expansion joint.
The bulk material of expansion joint is rubber, has compared with large displacement compensation capability, can compensate multiple directions, has the vibrations of minimizing, reduces noise and certain antiseptic power.
Adopted technique scheme, the beneficial effects of the utility model are:
The utility model is connected to the outside that left and right is taken over, install and change easily, the setting of metal stiffening ring, increased the withstand voltage properties of expansion joint, selecting of rubber material, expansion joint is had compared with large displacement compensation capability, can carry out the compensation of axial, horizontal and angular displacement, have the noise of reduction, reduce vibrations and certain antiseptic power.Simple in structure, low, the withstand voltage height of cost, displacement amount are large, long service life.
Therefore, the utility model, compared with existing expansion joint, has outstanding advantage and is: the bulk material of (1) expansion joint is rubber, has compared with large displacement compensation capability, can compensate the displacement of multiple directions, has the vibrations of minimizing, reduces noise and certain antiseptic power; (2) three ripple peak-like convexes are set on expansion joint, at middle crest shape high spot, metal stiffening ring are set, stiffening ring increases the withstand voltage properties of expansion joint; (3) expansion joint is arranged on the outside of left and right adapter, installs and changes easily, good sealing effect; Applicable to the pipeline that error is large, install, mounting process is simple.
A kind of novel expansion joint that the utility model provides, have compared with large displacement compensation capability, can carry out the compensation of axial, horizontal and angular displacement, this expansion joint is fixedly connected on left adapter and right adapter outside, easy to operate, on body, there are three ripple peak-like convexes, at middle crest shape high spot, also have metal stiffening ring, increased greatly the withstand voltage properties of this expansion joint.This model utility is simple in structure, and cost is low, good springiness, withstand voltage height, displacement amount are large, and vibration-absorbing denoising is effective, long service life.
