Detailed description of the invention:
Embodiment: by particular specific embodiment, embodiment of the present utility model is described below, those skilled in the art can understand other advantages of the present utility model and effect easily by content disclosed in the present specification.
The silencing means of steam (vapor) outlet as shown in Figure 1, Figure 2, Figure 3 and Figure 4, comprises main body 1, plunger type check valve 2, chock plug 3 and vent body 4.Main body 1 is threaded connection mode and pot body is connected, main body 1 top exterior walls 103 is connected with chock plug 3 inwall 301 and coordinates, plunger type check valve 2 is placed in main body 1 top, the outer wall 201 of plunger type check valve 2 contacts with body top inwall 104 and moves up and down within the scope of its top interior, and chock plug 3 is connected with vent body 4 by outside wall surface.The steam of HTHP flows up into the inwall of main body 1 from the bottom of the quick links of Boiler Steam shown in Fig. 1 device, its initial pressure is large, temperature is high, flow velocity is fast, through the silencing means inwall that internal diameter is expanded gradually, the plunger type check valve 2 be placed in main body 1 top backs down by the High Voltage of himself, steam progresses into along the gap between plunger type check valve and main body inner wall storehouse of reducing pressure, this moment, storehouse internal volume expands, steam pressure diffusion reduces, the sound wave of steam is also diffused in interior storehouse accordingly, acoustic wave segment friction in by interstitial gap process turns thermal energy consumption, rear steam changes again the flow direction by the air guide port 303 that chock plug 3 is vertically arranged and moves downward, the air guide port 303 of vent body 4 inner chamber and chock plug 3 is through, the Horizontal vents 401 that steam is introduced into vent body 4 is discharged.
As shown in Figure 1, main body 1 lower inner wall has wedge-like opening, and this is that both are sealed by wedge ring, and this kind of encapsulating method can prevent the leakage of steam better in order to better coordinate with the support component of lower pot body.
As shown in Figure 1 and Figure 2, lower inner diameter and the top internal diameter of main body 1 vary in size, lower inner diameter is less than top internal diameter, this is in order to make plunger type check valve 2 energy safety " seat " in main body 1, the skewed surface 202 of plunger type check valve contacts with the internal wall transitions place of main body 1, the difference of the two internal diameter transition position is 2mm, and chamfering is 135 °.
As shown in Figure 1, Figure 2, Figure 3 shows, plunger type check valve 2 is placed in the top of main body 1, plunger type check valve is vertical motion in its top, when plunger type check valve 2 is got on by steam top, its lower surface leaves main body 1, steam is moved upward gradually by gap between the two, and the step-down erasure effect of the clearance distance thus between plunger type check valve 2 and main body 1 top inner wall to steam is even more important, and the top inner surface surface processing accuracy of regulation main body 1 is Ra0.8.
As shown in Figure 1, Figure 2, Figure 3 shows, there is the surface processing accuracy of the plunger type check valve 2 of relative displacement relation to be also Ra0.8 with main body 1.
As shown in Figure 3, plunger type check valve 2 needs the impact experiencing high temperature and high pressure steam, completes the first task to steam pressure-reducing cooling, and this plunger type check valve needs to use carbon steel material to process.
As shown in Figure 4, chock plug 3 is provided with vertical air guide port 303, and this is to change the original flow direction of steam, flows straight down from becoming straight up, and in order to make steam more fast and effectively by chock plug, the air guide port number of this chock plug is set to 8.
The air guide port different through direction and steam vent, the pressure of steam is lowered again, the noise decibel produced meets the requirement of " industrial enterprise's noise criteria " completely, and a large amount of experimental datas shows, the noise decibel that the noise decibel that this kind of project organization produces produces than original structure is low by 30%, is the silencing means of effective steam (vapor) outlet.
