In description of the present utility model, it should be noted that unless otherwise clearly defined and limited, term " peace Dress ", " being connected ", " connection " should be interpreted broadly, for example, it may be fixedly connected, or be detachably connected, or integratedly Connection；Can be mechanically connected, or electrically connect；Can be joined directly together, it is also possible to be indirectly connected to by intermediary, It can be the connection of two element internals.For the ordinary skill in the art, can be by concrete condition understanding State concrete meaning of the term in this utility model.

Below with reference to the accompanying drawings and in conjunction with the embodiments describing this utility model in detail.

As illustrated in fig. 1 and 2, a kind of steam evacuation device that the present embodiment is provided, which includes safe valve outlet tube 2, emptying Pipe 4 and pallet 3, safe valve outlet tube 2 are arranged on above blow-down pipe 4, and safe valve outlet tube 2 is socketed with blow-down pipe 4, and relief valve goes out Exhaust passage 6 of the mouth pipe 2 with diameter greater than socket place one annular of formation of blow-down pipe 4, safe valve outlet tube 2 and blow-down pipe 4.

As steam passes through from safe valve outlet tube 2, a part of steam is directly entered from blow-down pipe 4, some from Exhaust passage 6 is discharged, and such a process is caused outside the effective discharge line of steam.

It is possible to throw into question the safety of workers at scene in view of the overheated steam from exhaust passage 6 out, thus Pallet 3 is arranged on 6 bottom of exhaust passage, pallet 3 is arranged on the outer wall of blow-down pipe 4 and towards safe valve outlet tube 2.Here Set pallet 3 can effectively stop the direct injection of steam, increase safety of workers coefficient.

It should be noted that because pallet 3 be subject to vapor impulsive force, in order to ensure the stability of pallet 3, here Pallet 3 is welded together with 4 outer wall of blow-down pipe.Also reduce because pipeline is rocked and make pallet 3 danger for coming off occur, so as to Increased service life and safety.

3 material of pallet is carbon steel.Carbon steel because its cost it is lower than rustless steel, and carbon steel generally than stainless intensity more Height, from consideration is counted in advance in, carbon steel is more suitable selection.

In view of when steam is through safe valve outlet tube 2, because jet chimney has vibrations, in safe valve outlet port The outer wall of pipe 2 is provided with the first leading truck 1；Outer wall in blow-down pipe 4 is provided with the second leading truck 5 simultaneously.Pipeline produces vibrations The reason for be：Fluid is subject to sufficiently large resistance of ducting turbulization, and then the impact of shape twin conduit in pipeline.Condensed water Do not drain in time, high velocity vapor impact condensed water defines vibrations, and this vibrations endanger very big to jet chimney, thus arrange Leading truck is necessary.

First leading truck 1 is clip, and the first leading truck 1 is setting parallel to the ground.Clip is 13 nut 12 of bolt Locking, the locking of 13 nut of bolt 12 include the ring body 11 of a breach, and the two ends of ring body 11 are equipped with evagination flanging, two evaginations folding Side is provided with corresponding installation fastener hole, and two evagination flangings are by being located in 13 phase of bolt installed described in two in fastener hole Even, and fastened by nut 12.The clip being so configured.Same second leading truck 5 is also clip, is fixed and mounting means It is as described above identical, repeat no more.

Above-mentioned this clip fixed form, can be by adjusting nut 12, to be adjusted to clip size, so as to increase The scope of application.Nut 12 is locked or is decontroled according to the different pipe diameters of blow-down pipe 4 and safe valve outlet tube 2, so as to Reach fixed purpose.

Depth depth of the blow-down pipe 4 along the axial direction of safe valve outlet tube 2 can be 30mm, 40mm, 50mm or 60mm.According to Different working conditions and Production requirement, depth depth of the blow-down pipe 4 along the axial direction of safe valve outlet tube 2 is variable.

6 radical length of exhaust passage can be 5mm, 6mm, 7mm, 8mm, 9mm or 10mm.Exhaust passage described herein 6 diameters are calculated according to thermal expansion, and the temperature of the pipeline passed through according to steam is different, so as to cause the different journeys of pipeline The expansion and contraction of degree.

A kind of steam evacuation apparatus structure that this utility model is provided is simple, easy to use, is filled using this steam evacuation Put, arrange easy, use range is wide.So as to save maintenance expense of the later stage to complicated steam evacuation device.Secondly, in blow-down pipe The pallet of upper setting, simply and effectively prevents from scalding.Safe valve outlet tube forms the aerofluxuss of an annular with blow-down pipe Passage, this convenient operation is simple and row's steaming effect is good.

Preferred embodiment of the present utility model is the foregoing is only, it is not to limit this utility model, all at this Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc. should be included in this utility model Protection domain within.
