Abstract
The invention relates to a novel expansion joint with large displacement compensation capacity. The novel expansion joint can conduct compensation of axial, transverse and angular displacement, is fixedly connected between a left connection pipe and a right connection pipe through bolts, nuts and gaskets, and is installed on the outer side of the connection pipes. Operation is convenient. An expansion joint body is made of rubber and provided with three crest-shaped protrusions; a metal reinforcing ring is arranged at the crest-shaped protrusion in the middle, and the pressure-resistant property of the novel expansion joint is increased greatly. The novel expansion joint is simple in structure, low in cost, good in elasticity, high in pressure resistance, large in displacement, good in vibration absorption and noise reduction effect and long in service life.
Description
Technical field
The present invention relates to a kind of expansion joint, particularly a kind of non-metal expansion joint.
Background technique
Expansion joint is the additional stress compensated because temperature difference and mechanical vibration cause, and is arranged on a kind of flexible structure on container shell or pipeline.Due to it as a kind of can the elastic compensation element of 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, being utilize effective dilatation of the elastic element of corrugated expansion joint to absorb pipeline, conduit or container by reason and a kind of compensation device of the dimensional changes produced such as expanding with heat and contract with cold, belonging to a kind of compensating element.Expansion joint can to the absorption of axis, transverse direction and angular displacement, for pipeline, equipment and system add thermal walking, mechanical displacement absorbs vibration, reduce noise etc.Non-metal expansion joint can the product such as compensating axial, transverse direction, angle, has without thrust, simplifies the features such as susceptor design, corrosion-resistant, high temperature resistant, silencing vibration-damping, be specially adapted to hot air duct and fume ducts.Be currently used in the expansion joint of industrial system, general employing metallic sheath core structure, be made up of inside and outside sleeve, by seal with O ring between inside and outside sleeve, structure bulky, displacement amount is little, and cost is high.
It is heavy that the present invention will overcome existing expansion joint structure exactly, and displacement amount is little, the deficiency that cost is high, provides one to compensate multiple directions, is greatly better than Pipelines with Single Direction Compensation.In pipeline connection procedure, the appearance of systematic error is can hardly be avoided, so non-metal compensator compensate for alignment error preferably.Scrap metal material in non-metal compensator itself has the function of sound absorption, vibration isolation, effectively can reduce the noise and vibration of the system such as boiler, blower fan and certain antiseptic power.Structure is simple, body is light, manufacture, easy to maintenance, cost is low, long service life.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of novel expansion joint, there is larger displacement compensation ability, the compensation of axis, transverse direction and angular displacement can be carried out, this expansion joint is fixedly connected between left adapter and right adapter, couple together with bolt and nut and pad respectively, be arranged on the outside of adapter, easy to operate, the material of this expansion joint body is rubber, body has three ripple peak-like convexes, also have metal stiffening ring at the crest shape high spot of centre, add the withstand voltage properties of this expansion joint greatly.This invention structure is simple, and cost is low, good springiness, withstand voltage height, displacement amount large, and vibration-absorbing denoising is effective, long service life.
In order to solve the problem, the present invention is achieved through 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.Expansion joint there are three ripple peak-like convexes, also have metal stiffening ring at the crest shape high spot of centre, increase withstand voltage properties, bulk material is rubber, there is larger displacement compensation ability, the compensation of axis, transverse direction and angular displacement can be carried out, have and reduce noise, minimizing 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 flange from bearing water corrosion.
Expansion joint two ends tighten together with two pipe nipples with bolt, nut, pad respectively, seal excellent, compact structure.
Expansion joint is arranged three ripple peak-like convexes, arrange metal stiffening ring at the crest shape high spot of centre, stiffening ring increases the withstand voltage properties of expansion joint.
The bulk material of expansion joint is rubber, has larger displacement compensation ability, can compensate multiple directions, has and reduces vibrations, reduction noise and certain antiseptic power.
Have employed technique scheme, the invention has the beneficial effects as follows:
The present invention is connected to the outside of left and right adapter, install and change easily, the setting of metal stiffening ring, increase the withstand voltage properties of expansion joint, selecting of rubber material, make expansion joint have larger displacement compensation ability, the compensation of axis, transverse direction and angular displacement can be carried out, have and reduce noise, minimizing vibrations and certain antiseptic power.Structure is simple, and low, the withstand voltage height of cost, displacement amount are large, long service life.
Therefore, the present invention, compared with existing expansion joint, has outstanding advantage and is: the bulk material of (1) expansion joint is rubber, has larger displacement compensation ability, the displacement of multiple directions can be compensated, have and reduce vibrations, reduction noise and certain antiseptic power; (2) expansion joint is arranged three ripple peak-like convexes, arrange metal stiffening ring at the crest shape high spot of centre, 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; Be applicable to the Pipe installing that error is large, mounting process is simple.
A kind of novel expansion joint provided by the invention, there is larger displacement compensation ability, the compensation of axis, transverse direction and angular displacement can be carried out, this expansion joint be fixedly connected on left adapter and right take over outside, easy to operate, body has three ripple peak-like convexes, also has metal stiffening ring at the crest shape high spot of centre, add the withstand voltage properties of this expansion joint greatly.This invention structure is simple, and cost is low, good springiness, withstand voltage height, displacement amount large, and vibration-absorbing denoising is effective, long service life.
