Abstract
The utility model relates to an anti drawing off high pressure joint, which comprises a drum shaped rubber mass and flanges at the both ends of the rubber mass. The utility model is characterized in that: a ring steel band is compounded in the drum shaped rubber mass, the external layer of which is clap by an elastic layer. With simple structure, light weight and greatly prolonged service life, the utility model is applicable to petroleum mechanical field.
Description
Technical field
The utility model relates to a kind of high pressure joint.
Background technique
In foundation engineerings such as chemical industry, building, plumbing, oil, hot-water heating, freezing, fire-fighting, electric power, often to use various pipelines, at a certain distance a pipe joint must be installed between the employed rigid conduit, in order to overcome axial displacement, angular displacement, the lateral displacement between the rigid conduit, the difficulty that factors such as flange is not parallel cause to construction often adopts the flexible elastomer connector to finish connection work between the rigid conduit.Existing elastomer connector is made of the rubber flange at cydariform colloid and its two ends, because the rubber flange material at cydariform colloid and its two ends is softer, the problem that cydariform colloid and rubber flange pull in use can occur, and causes adverse effect to ordinary production.If pressure is excessive in the pipeline, the joint also can produce explosion, leakage, influences working life greatly.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of anti-slip high pressure joint and has solved the defective that lack working life in the prior art.
Technological scheme
The utility model provides a kind of anti-slip high pressure joint, comprises the flange at cydariform colloid and its two ends, is compounded with ring steel belt in the cydariform colloid, and its skin is wrapped with one deck elasitic layer.
End face at flange is equipped with clamp flange, on the end face of flange annular groove is arranged, and the annular protrusion adaptive with annular groove arranged on the end face of clamp flange, and the fastener hole on two flanges is corresponding mutually, is compounded with the steel wire ring in clamp flange.
Beneficial effect
The high pressure joint of this anti-slip rubber is widely used in foundation engineerings such as chemical industry, building, plumbing, oil, hot-water heating, freezing, fire-fighting, electric power.Can not be subjected to the pipeline decentraction, the uneven restriction of flange, can reduce structure-borne noise, damping capaicty strong, use flexible, easy for installation, in light weight, bear pressure height, good springiness, be convenient to change and repair, reduce labor intensity, with water pump, supporting, heat-resisting, the corrosion resistant, ageing-resistant of valve.Owing in clamp flange, be compounded with steel loop, can not occur disk stripping in the work and pull phenomenon, can prevent effectively that sealing hangs down.
Alternative bushing type expansion bend of this product and choked flow coefficient are little, compare in light weight 2/3 with cast iron bushing type expansion bend.
The utility model skin has one deck elasitic layer to reduce wearing and tearing, greatly the working life of Zeng Jiaing.
