Abstract
The utility model discloses a loose tube expansion joint with flat-face flange type. The loose tube expansion joint comprises a flange plate; an expansion joint is matched with an inclined plane of one side of the flange plate; a seal groove is arranged in the expansion joint; a seal ring is matched in the seal groove; and a plurality of annular cavities are arranged in the seal ring. The loose tube expansion joint provided by the utility model is matched with different valves while in use, so that the assembly and disassembly of the valves are more convenient and the operation of pipes are safer and more reliable; the loose tube expansion joint has light weight and great compensation quality; when the loose tube expansion joint is pressed at the periphery of the pipes, the pipes are pressed and connected by the slant angles between the loose tube expansion joint and the peripheries of the pipes.
Description
Technical field
The utility model relates to the pipe first-aid field, specifically belongs to the expansion joint of face-flange formula pine cover.
Background technique
Expansion bend is also claimed slip joint, expansion joint, compensator.But expansion bend is axial stretching within the specific limits; Also can in certain angle, overcome pipeline butt joint disalignment to and the skew that produces; Can greatly facilitate the installation and removal of valve pipe; In pipeline allows extending amount, can freely stretch, just play spacingly, guarantee the safe operation of pipeline in case cross its maximal dilation amount.Be mainly and ensure the pipe safety operation, have following effect: the compensation extraction duct is axial, horizontal, the angle thermal distortion; The absorption equipment vibration reduces the influence of vibration equipment to pipeline; Absorb earthquake, earth subsidence amount of deformation to pipeline.
The model utility content
The purpose of the utility model provides cover expansion joint of a kind of face-flange formula pine and the supporting use of various valve, makes the valve loading and unloading more convenient; Make the pipeline operation safer, reliable, in light weight, compensation rate is big; Rely on mutual gradient, be pressed on peripheral device sealing of pipe and interconnect function.
The technological scheme of the utility model is following:
The expansion joint of face-flange formula pine cover includes flange plate, and a skew back face of flange plate is combined with expansion joint, is provided with seal groove in the expansion joint, is combined with seal ring in the seal groove, is provided with a plurality of toroidal cavities in the seal ring.
The cross section of described seal ring is trapezoidal.
After the pine of the utility model cover telescopic head was installed on the pipeline, fastening nut, elastic seal ring made the valve loading and unloading more convenient under the pressure of nut, gland and the supporting use of various valve, make the pipeline operation safer, reliable, in light weight, and compensation rate is big.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
