Description of drawings
accompanying drawing 1 is looked the sectional structure sketch map for the master of the utility model most preferred embodiment.
accompanying drawing 2 is that the A-A of accompanying drawing 1 is to the sectional structure sketch map.
Coding in
accompanying drawing is respectively: 1 is pipe in the blending, and 2 are the blending outer tube, and 3 is the body cavity, and 4 is gasket ring, and 5 is the mist pipe base, and 6 is mist pipe, and 7 is toroidal cavity, and 8 is orifice, and 9 is annular concave platform, and 10 is annular boss.
The specific embodiment
the utility model does not receive the restriction of following embodiment, can confirm concrete embodiment according to the technical scheme and the actual conditions of the utility model.
are in the utility model; For the ease of describing; The description of the relative position relation of each parts all is to describe according to the Butut mode of Figure of description 1, as: the position relation of forward and backward, upper and lower, left and right etc. is what to confirm according to the Butut direction of Figure of description.
Below in conjunction with embodiment and accompanying drawing the utility model is further described:
like accompanying drawing 1, shown in 2, this oil field overheat steam injection boiler blending device comprises pipe 1, blending outer tube 2 and mist pipe 6 in the blending; The external diameter of pipe 1 is less than the internal diameter of blending outer tube 2 in the blending; Pipe 1 is fixedly mounted in the inner chamber of blending outer tube 2 in the blending; Form the body cavity 3 of annular in the blending between pipe 1 and the blending outer tube 2; Be installed with mist pipe base 5 on the right part of blending urceolus 2, mist pipe 6 is fixedly mounted in mist pipe base 5 internal cavities and the bottom is positioned at blending pipe 1 inside, and there is at least one row's orifice 8 in the left side, lower end of mist pipe 6.Pipe 1 is selected the thin steel pipe of wall thickness for use in the blending, because about 500 ℃ of the superheat steam temperature through interior pipe, and from about 300 ℃ of the high saliferous saturation water temperature of mist pipe 6 apertures ejection; The temperature difference is bigger; Select for use the thin steel pipe of wall thickness as managing 1 in the blending, can adapt to preferably that near the blending that high saliferous saturation water caused of the aperture ejection of mist pipe 6 pipe 1 tube wall local temperature is fallen suddenly and the STRESS VARIATION that causes is avoided cracking; Prolong the service life of blending device; Simultaneously, the air in the body cavity 3 in blending outer tube 2 and the blending between the pipe 1 can produce good insulation effect, effectively reduces the radiation loss of blending device; Mist pipe 6 is drilled with many row's orifices 8 towards the port of export of steam, and the position of orifice 8 and diameter must satisfy high saliferous saturation water and when ejection, keep complete spray pattern.
