Embodiment
Below in conjunction with accompanying drawing, summary of the invention is described further:
With reference to shown in Fig. 1, travelling speed is the passage control speed device of the steam of velocity of sound, be included in for by travelling speed be on the vapour passage of velocity of sound cover be wound with hollow cavity 2, it is conducted by the same vapour passage for being velocity of sound by travelling speed in the inside of the hollow cavity 2 described in the perforate at two ends, the two ends of described hollow cavity 2 are connected by the same vapour passage for being velocity of sound by travelling speed of flange 3, the two ends of described hollow cavity 2 are end cylindrical toroidal body 4, one end of two hollow round table bodies 5 of hollow cavity 2 is conducted with the cylindrical toroidal body 4 at the two ends of hollow cavity 2 respectively, one end that two hollow round table bodies 5 are conducted with the cylindrical toroidal body 4 at the two ends of hollow cavity 2 respectively is less one end, the aperture of hollow round table body 5, like this for by travelling speed be velocity of sound vapour passage in travelling speed be that the steam of velocity of sound enters the effect that cylindrical toroidal body 4 can play the buffering transition that travelling speed slows down, so just it is unlikely to the effect forfeiture causing the control speed of hollow container to become slow owing to travelling speed is too fast, and have passed through the steam after hollow container due to travelling speed continued to become slow after also flow out stably by the effect of transition buffer of hollow round table body 5, so just it is unlikely to unstable outflow, the other end of two described hollow round table bodies 5 is conducted with the two ends of the middle part cylindrical toroidal body 6 of hollow cavity 2 respectively, the outer wall of described middle part cylindrical toroidal body 6 coils annular projection 7, the baffle plate 8 that outer wall embeds annular projection 7 it is provided with in hollow cavity 2 inside, through baffle plate 8 is hollow container 9, it is conducted with the inside of hollow cavity 2 by the inside of the hollow container 9 described in the perforate at two ends, the exterior contour of described hollow container 9 is cylindrical shape, and described end cylindrical toroidal body 4, hollow round table body 5, middle part cylindrical toroidal body 6 and hollow container 9 right alignment, described hollow container 9 inside is axially symmetric structure, this hollow container 9 in-profile is linked together by fillet 12 transition between the hollow circular arc column body 10 of left part part and the hollow round table body 11 of right part, and the inductive means of the test element corresponding to the test of steam parameter is arranged on the entrance of vapour passage 1 that travelling speed is velocity of sound and travelling speed be velocity of sound steam passage control speed device between vapour passage 1 in. the longitudinal span of the left end of the hollow circular arc column body 10 of described left part part span more longitudinal than the right-hand member of the hollow circular arc column body 10 of left part part is big, and the longitudinal span span more longitudinal than the right-hand member of the hollow round table body 11 of right part of the left end of the hollow round table body 11 of described right part is little. the length of described hollow container 9 can be that the steam travelling speed that the size of vapour passage 1 of velocity of sound, the steam travelling speed upper limit of the inductive means of test element adjust to be reached through the inductive means of the test element corresponding to the test of steam parameter is less than the described steam travelling speed upper limit according to travelling speed.
The principle of work of the present invention be for by travelling speed be velocity of sound vapour passage in travelling speed be that the steam of velocity of sound enters after cylindrical toroidal body 4 can play the buffering transition that steam travelling speed is slowed down, steam enters the hollow circular arc column body 10 of left part part again, by the longitudinal span span more longitudinal than the right-hand member of the hollow circular arc column body 10 of left part part of the left end of the hollow circular arc column body 10 of its left part part big when, the right-hand member of the hollow circular arc column body 10 of left part part that steam is diminished by longitudinal span arrives fillet place, the right-hand member of the hollow round table body 11 of the right part described in then increasing from longitudinal span again via fillet place steam flows out, like this when vapor pressure enter travelling speed be velocity of sound steam passage control speed device before keep constant, the decrease in velocity of steam will be caused like this thus meet the control overflow of steam travelling speed entering after based on the automatic steam control speed device under factor stroke reactive force gradually like this.
The above, it it is only the better embodiment of the present invention, not the present invention is done any restriction in form, although the present invention discloses as above with better embodiment, but and be not used to limit the present invention, any those skilled in the art, do not departing within the scope of technical solution of the present invention, make a little change when the technology contents of above-mentioned announcement can be utilized or it is modified to the equivalent embodiment of equivalent variations, in every case it is do not depart from technical solution of the present invention content, according to the technical spirit of the present invention, within the spirit and principles in the present invention, the any simple amendment that above embodiment is done, equivalent replacement and improvement etc., all still belong within the protection domain of technical solution of the present invention.
