Accompanying drawing explanation
Be described in further detail this use is novel below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation of the utility model steam discharge muffler;
In figure: 1-silencer cylinder, 2-take over the import of cylinder core, 21-enlarged diameter section, 22-cylinder core changeover portion, 23-reduced diameter section, 31-the first end socket, 32-the second end socket, 4-restricting orifice, 5-supporting tripods, 6-hanger, 7-reinforcement dividing plate, 8-adapter cylinder core.
Embodiment
Steam discharge muffler shown in Fig. 1 comprise silencer cylinder 1, in be located at the adapter cylinder core 2 of silencer cylinder 1, silencer cylinder 1 one end is closed end, which is provided with the first end socket 31 for sealing, silencer cylinder 1 the other end is connecting end, and itself and take over cylinder and be provided with the second end socket 32 for sealing between core 2, the second end socket 32 of silencer cylinder 1 with take over a core 2 and be connected with welding manner.; One end of taking over cylinder core 2 is the inner that is placed in silencer cylinder 1, and the other end is the outer end that exposes to silencer cylinder 1, the import 8 that the outer end opening of taking over cylinder core 2 is silencing apparatus; Take in cylinder core 2 and be provided with at least one deck restricting orifice 4, and on the barrel of silencer cylinder 1, be laid with multiple noise elimination apertures.The sidewall of silencer cylinder 1 is provided with multiple supporting tripodss 5, and supporting tripods 5 can fixedly mount with the support that manufacture forms according to site specific, plays the effect of location steam discharge muffler.On the first end socket 31 of silencer cylinder 1, be also provided with hanger 6, utilize this hanger 6 can make the installation and removal of steam discharge muffler become convenient laborsaving.On the barrel of silencer cylinder 1, be laid with multiple noise elimination apertures, the diameter of noise elimination aperture remains within the scope of 1 ~ 3mm, and the gross area of all noise elimination apertures is more than or equal to the twice of muffler inlet 8 areas.The import 8 of silencing apparatus is communicated with corresponding steam outlet sealing, and steam enters in silencing apparatus by this import 8.Adapter cylinder core 2 is placed in the inner of silencer cylinder 1 to be continued to extend to silencer cylinder 1 top the position that approaches the first end socket 31, adapter cylinder core 2 inside that are arranged in silencer cylinder 1 are provided with multilayer restricting orifice 4, the number of plies of restricting orifice 4 is preferably one to four layer according to actual exhaust steam pressure, so that the vapor pressure while entering micropore jet is only higher for good than barometric pressure.Enter the steam of taking over cylinder core 2 successively by restricting orifice 4, its pressure also declines step by step, makes to reach a suitable numerical value by the vapor pressure after last one deck restricting orifice 4.
Taking over cylinder core 2 according to the difference of steam discharge parameter can form with upper-part by 3 or 3, adapter cylinder core 2 in the present embodiment comprises that enlarged diameter section 21, reduced diameter section 23 and connection enlarged diameter section 21 and reduced diameter section 23 are trumpet-shaped cylinder core changeover portion 22, and the large one end internal diameter of cylinder core changeover portion 22 openings equals the internal diameter of enlarged diameter section, the little one end internal diameter of cylinder core changeover portion 22 openings equals the internal diameter of reduced diameter section.Steam enters by cylinder core changeover portion 22 major diameter 21 that internal diameter is larger from the less reduced diameter section 23 of internal diameter, and the volume of its steam increases, pressure decreased.Take over the inner that cylinder core 2 is arranged in silencer cylinder 1 and seal for being provided with sealing plate, and offer multiple uniform apertures on the barrel of adapter cylinder core (2) between sealing plate and restricting orifice, the diameter of these apertures is between 5 ~ 12mm.After the aperture of steam on the barrel by taking over cylinder core 2, pressure and the speed of steam further reduce, and according to the difference of steam flow, pressure and temperature, the little hole number on the barrel of adapter cylinder core 2 is also different.The steam that aperture from the barrel of adapter cylinder core 2 is discharged is finally by the noise elimination aperture ejection on silencer cylinder 1, in the time that the vapor (steam) velocity by noise elimination aperture is enough high, noise elimination aperture can be shifted to high frequency by the frequency spectrum of exhaust noise, audible sound part in noise spectrum is reduced, thereby reduced the interference of Noise upon Environment.
Between silencer cylinder 1 and an adapter core 2, approach the first end socket 31 and the second end socket 32 places and be also welded with polylith reinforcement dividing plate 7, strengthen having through hole on dividing plate 7, strengthen dividing plate 7 and play the effect that connects and reinforce silencer cylinder 1 and take over cylinder core 2, improve the integrated connection intensity of steam discharge muffler.The second end socket 32 at silencer cylinder 1 is laid with two symmetrical through holes, and the steam condensate in silencer cylinder 1 can be discharged by through hole.
