the utility model provides a high temperature high pressure steam pipeline to power plant exhaust steam, includes the pipeline body, and the inner wall of pipeline body is fixed and is equipped with the bayonet socket piece, is equipped with heat preservation, heat insulation layer from inside to outside in the bayonet socket piece in proper order.

Further, the junction of pipeline body is equipped with the storage tank, and the junction of pipeline body is fixed to be equipped with solid fixed ring, is equipped with the internal thread on solid fixed ring's the inner wall, and the one end that the junction was kept away from to the pipeline body is equipped with the isolating ring board, and the part that the pipeline body is close to the isolating ring board is equipped with the external screw thread.

Further, the inner diameter of the fixing ring is consistent with the outer diameter of the pipeline body.

Furthermore, the fixing ring comprises an upper half ring and a lower half ring, through holes are formed in the upper half ring and the lower half ring respectively, and bolts used for fixing the upper half ring and the lower half ring are arranged in the through holes.

Furthermore, the surface of the bayonet block is an arc surface.

To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:

1. the utility model discloses in, when the installation, the gap can be avoided having when the installation between the current segmentation heat preservation to the department of will segmenting fills in the bayonet socket piece in the installation, leads to producing the heat loss, because of being equipped with the heat insulation layer, so can avoid producing the heat loss, therefore improved the heat preservation effect of heat preservation, also avoid the condition that pipeline body scalds the staff to appear.

2. The utility model discloses in, when passing through threaded connection between pipeline body and the pipeline body, the isolating ring board can the holding in the storage tank, and then avoids the heat loss of heat preservation junction to pipeline body transmission, has fixed the junction between the pipeline body because of the fixed ring, so also further avoids high temperature high pressure steam outwards to give off to cause the heat loss, also stopped the potential safety hazard.

3. The utility model discloses in, solid fixed ring's internal diameter is unanimous with the external diameter of pipeline body, can make the fixed pipeline body of fixed ring, avoids appearing the condition of heat loss.

4. The utility model discloses in, go up the semi-ring, the semi-ring passes through the bolt fastening down, and not only convenient to detach connects, still makes the installation between pipeline body and the pipeline body more firm.

5. The utility model discloses in, the surface of bayonet block is the pressure when the reducible pipeline body of cambered surface transmits high temperature high pressure steam.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

The utility model provides a high temperature high pressure steam pipeline to power plant exhaust steam, includes pipeline body 1, and the inner wall of pipeline body 1 is fixed and is equipped with bayonet block 11, is equipped with heat preservation 12, heat insulating layer 13 from inside to outside in the bayonet block 11 in proper order.

Further, the junction of pipeline body 1 is equipped with storage tank 14, and the fixed solid fixed ring 2 that is equipped with in junction of pipeline body 1 is equipped with the internal thread on the inner wall of solid fixed ring 2, and the one end that pipeline body 1 kept away from the junction is equipped with isolating ring board 15, and the part that pipeline body 1 is close to isolating ring board 15 is equipped with the external screw thread.
