Domain.
To achieve the above object, the technical solution adopted in the utility model is as follows:
Bending rubber joint, including body of rubber, and it is separately positioned on the flange at body of rubber both ends, the rubber master
Body is cylindrical in shape, and spherical redundancy protrusion is equipped in the middle part of body of rubber；The flange is set on the outside of body of rubber end, flange
Outer surface is equipped with the bayonet slot of a ring shape, and the body of rubber end edge is then first towards bending, again court on the outside of body of rubber
In the bayonet slot for being caught in flange after to bayonet slot bending, to realize the locking of body of rubber and flange；The body of rubber end edge
Annular reinforcing ring is equipped in the part that edge is bent towards body of rubber outside；The body of rubber be by inside and outside two layers of rubber layer and
Middle layer enhancement layer is crosslinked by high temperature and pressure to be combined, and is also uniformly provided with several steel ring layers in body of rubber.
Preferably, the enhancement layer is polyester cord layer.
Preferably, the enhancement layer is 66 dipped type cord fabric of polyamide fibre.
Preferably, the reinforcing ring is carbon steel ring, spheroidal graphite iron ring or stainless steel ring.
Preferably, the reinforcing ring is the 304 stainless steels circle more wirings of stock.
Compared with prior art, the utility model has the following beneficial effects:
(1) body of rubber of the utility model using rubber special performance (high resiliency, high-air-tightness, resistance to medium and
Weatherability), 66 dipped type cord fabric of polyester cord or polyamide fibre that joint is high-intensitive, cold and hot stability is strong is multiple through high temperature, high-voltage crosslinking
It closes, makes it have biggish multidirectional displacement function, elongation or compression (axial displacement) in fluid flow direction can be generated,
Also it can generate and the displacement of the vertical direction of fluid flow direction (radial displacement), moreover it is possible to both ends connected pipe be made to generate angle
Change (angular displacement)；In addition, the setting of its reinforcing ring, which is avoided that deformation is excessive, leads to not the problem of replying again.
(2) the utility model is well suited for complex geologic conditions, and pipeline foundation subsiding extent is big, the temperature difference greatly so as to cause
In the big pipe-line system of pipeline stroke, the pressure generated due to various reasons in pipeline can be effectively eliminated, obstructs and cuts down
The vibration and noise that the equipment such as pump, valve generate.
(3) the utility model flange and the unique connection of body of rubber are arranged, and can have the effect of tensing anticreep,
Avoid a series of problems for causing flange and body of rubber to fall off initiation because of external force.
(4) the utility model bending rubber joint has adaptability, which can be widely applied to municipal discharge
The cooling circulating water of water, thermal power plant and water-power plant and water supply, condensate line, chemical substance pipeline and its
The medium conveying of the solid powder and gas of its sweat.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Wherein, the corresponding title of appended drawing reference are as follows:
1- flange, 2- body of rubber, 3- steel ring layer, 4- enhancement layer, 5- reinforcing ring.
Specific embodiment
The utility model is described in further detail with embodiment for explanation with reference to the accompanying drawing, and the mode of the utility model includes
But it is not limited only to following embodiment.
The purpose of the present embodiment is can to adapt to more high requests to improve existing bending rubber joint
Environment specifically as shown in Figure 1, the bending rubber joint of the present embodiment includes body of rubber 2, and is separately positioned on rubber
The flange 1 at glue main body both ends, shape seem identical as connector in the prior art, but are substantially different, firstly, this
The body of rubber of embodiment is crosslinked and is combined by high temperature and pressure by inside and outside two layers of rubber layer and middle layer enhancement layer 4,
Several steel ring layers 3 are also uniformly provided in body of rubber, the high resiliency based on rubber material itself is crosslinked in conjunction with high temperature and pressure
Compound 66 dipped type cord fabric of polyamide fibre etc. makes it have elastomeric while also having great toughness and deformation-recovery performance, and
The steel ring layer of body of rubber liner can play the enhancing performances such as intensity again, made it have after composite portfolio geology subsiding extent compared with
The big or big region of the temperature difference uses necessary stroke and flexible amount, has biggish multidirectional displacement function.In addition, this
Embodiment flange and the connection type of body of rubber also with it is different in the prior art, due in the larger or change in displacement of some vibrations
In larger usage scenario, due to the difference of flange and body of rubber stress, flange and body of rubber is easily caused to be detached from, therefore,
The present embodiment improves this, and in the present embodiment, the flange 1 is set on the outside of 2 end of body of rubber, flange appearance
Face is equipped with the bayonet slot of a ring shape, and the body of rubber end edge then first towards bending on the outside of body of rubber, makes the bending
Side is parallel with flange, is caught in the bayonet slot of flange after being then re-directed towards bayonet slot bending, the common shape in the both sides entirely bent
At the L-shaped ring-type in a section, it can realize the locking of body of rubber and flange；Since rubber has certain deformation,
Therefore, the present embodiment is also in the body of rubber end edge towards being equipped with annular reinforcing ring in the part bent on the outside of body of rubber
5, the reinforcing ring 5 is the 304 stainless steels circle more wirings of stock, can play and stop to skid off outside flange rubber main body.
Detection discovery is carried out to the bending rubber joint of the present embodiment: the axial position of≤DN150 bending rubber joint
Shifting elongation >=12mm, decrement >=20mm, lateral displacement amount >=14mm, permission deflection angle maximum >=± 7.50, DN200~
Axial displacement elongation >=16mm of DN1400 bending rubber joint, decrement >=25mm, lateral displacement amount >=22mm allow
Deflection angle maximum >=± 7.50.It is mountable to water supply, draining and circulating water pipeline, hot-water heating ventilation shaft and in oiling formula pipeline
On, main function is vibration insulation and noise reduction, damage caused by supplementing piping displacement and preventing foundation settlement.
Above-described embodiment is only one of preferred embodiments of the present invention, should not be taken to limit the utility model
Protection scope, as long as the utility model body design thought and mentally make have no the change of essential meaning or profit
Color, it is solved the technical issues of it is still consistent with the utility model, the protection scope of the utility model should all be included in
