Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.
First, it should be noted that fig. 1 shows a preferred structure of the steam valve seat of the present invention, and this preferred structure is only used for explaining the steam valve seat 1, but the steam valve seat 1 is not limited, that is, the steam valve seat 1 is not limited to the structure shown in fig. 1, and those skilled in the art can make various modifications and substitutions to the structure of the steam valve seat 1 according to the following technical solutions and effects.
With reference to the structure shown in fig. 1, the steam valve seat 1 of the present invention includes a plate body 2, a drainage casing 3 is formed on the plate body 2, wherein, a plurality of spaced first baffles 11 are formed on an inner surface 4 of the plate body 2 located in the drainage casing 3 to form a steam drainage structure 5, the steam drainage structure 5 is used for forming a labyrinth-shaped steam flow channel 6 (as shown by an arrow in fig. 3), the inner surface 4 of one end of the steam drainage structure 5 has a steam inlet 8 which runs through an opening 7 of the plate body 2 to form the steam flow channel 6, and the other end of the steam drainage structure 5 is used for forming a steam outlet 9 of the steam flow channel 6.
Of course, it is preferable that the opening 7 extends in the entire width direction of the draft housing 3, that is, the opening 7 extends in the entire width direction of the first baffle 11.
In the technical scheme, a plurality of spaced first baffles 11 are formed on the inner surface 4 of the plate body 2 in the drainage shell 3, so that when the steam valve seat 1 is assembled with the steam valve cover 26 provided with a plurality of second baffles 12 at intervals, the plurality of second baffles 12 of the steam valve cover 26 and the plurality of first baffles 11 of the steam valve seat 1 are sequentially and alternately arranged, thereby forming a labyrinth-shaped steam flow channel, as shown by arrows in fig. 3, so that the steam valve seat 1 can effectively prolong the path of steam flow, and steam bubbles can be automatically broken when steam flows through each bending point of the labyrinth-shaped channel, thereby effectively preventing overflow.
Further, after the steam bubbles are broken, or in order to timely return the condensed liquid, to avoid accumulation in the steam flow passage 6, it is preferable that, as shown in fig. 1 and 3, the surface portions of the inner surface 4 separated by the first barrier 11 are formed with return holes 10 penetrating the plate body 2, that is, the portions of the inner surface 4 separated by the first barrier 11 are respectively formed with return holes 10, so that the liquid can be timely returned.
Further, as shown in fig. 3 and 4, a backflow check valve 32 may be provided on each backflow hole 10, the backflow check valve 32 being configured to allow backflow liquid to flow only from the interior surface 4 through the backflow hole 10, while preventing vapor from passing through the backflow hole 10 into the vapor flow path on the interior surface 4. For example, as shown in the figure, a large opening is formed on the plate body, a sleeve is supported on the inner peripheral surface of the opening through a plurality of support rods, a backflow hole 10 is formed between the support rods, the sleeve is provided with a mounting hole 31, and a backflow check valve 32 is arranged in the mounting hole 31 to close and open the backflow hole 10 to allow only liquid to flow back, so that under the steam pressure, the backflow check valve 32 closes the backflow hole 10, thereby preventing the steam from passing through, and when the steam pressure is weakened or disappears, the backflow check valve 32 descends, thereby backflow liquid on the inner surface 4 flows back.
Further, the backflow check valve 32 may have various structural forms, for example, in the structure shown in fig. 3 and 4, the backflow check valve 32 includes a rod body, one end of which is an elastic blocking flange having a diameter slightly larger than the inner diameter of the fitting hole 31, and the other end of which is a blocking plate capable of blocking all of the backflow holes, so that, after the elastic blocking flange is pressed to pass through the fitting hole 31 from bottom to top, the rod body of the backflow check valve 32 can be fitted into the fitting hole 31, and the length of the rod body is slightly larger than the axial length of the fitting hole 31, so that the backflow check valve 32 can move axially with respect to the fitting hole 31.
Of course, after the first baffle 11 is disposed on the inner surface 4, two sides of the first baffle 11 may have a certain gap with two side walls 13 opposite to the drainage housing 3. However, in order to allow the steam to flow along the labyrinth-shaped steam flow path 6 to flow through a longer path, it is preferable that both sides of the first baffle 11 are connected to both opposite side walls 13 of the draft housing 3 as shown in fig. 1, so that the entire steam is driven to flow upward and downward along the flow shown by the arrows of fig. 3 to flow forward, thereby lengthening the flow path.
In addition, in order to further lengthen the steam flow path and improve the anti-overflow effect, it is preferable that the draft housing 3 is rectangular in shape and the first baffle 11 is arranged along the length extension direction of the draft housing 3, as shown in fig. 1 and 3. In this way, the structure of the flow-inducing housing 3 itself can be utilized to arrange more first baffles 11 in its length extension, which correspondingly lengthens the steam flow channel 6, while more first baffles 11 also form more corners, which would break up bubbles in the steam.
Of course, the rectangular-shaped flow guide housing 3 may have various structural forms, for example, in order to simplify the structure and to make full use of the steam valve cover 26 when assembled, preferably, as shown in fig. 1, the flow guide housing 3 is a U-shaped plate 14, the side plate portions 15 and the bottom plate portion 16 of the U-shaped plate 14 are simultaneously connected to the plate body 2, wherein each first baffle plate 11 is connected to both side plate portions 15, and the opening 7 is located between the bottom plate portion 16 and the outer first baffle plate 11, and the opening portion 17 of the U-shaped plate 14 is used to form the steam outlet 9. Thus, the steam guide structure 5 of the present invention can be simply formed by the simple U-shaped plate 14 and the first baffle 11.
Of course, the utility model discloses an in the steam valve seat 1, steam outlet 9 can directly lead to the outside, that is, this steam valve seat 1 and steam valve gap 26 assembly back, steam outlet 9 can directly pass the steam valve gap in order to lead to the outside. However, in order to further enhance the anti-overflow effect, it is preferable that the steam valve seat 1 further comprises a steam discharge chamber 19 arranged around the steam flow channel 6, for example, the peripheral edge of the plate body 2 is formed with an annular rib 18, and the steam discharge chamber 19 communicating with the steam outlet 9 is formed between the flow guide housing 3 and the annular rib 18, as shown in fig. 1, 3 and 4. In this way, the steam discharge chamber 19 can be regarded as an enlarged section of the steam flow channel 6, so that after the steam discharged from the steam outlet 9 enters the steam discharge chamber 19, the pressure of the steam is significantly reduced because the space of the steam discharge chamber 19 is larger than that of the steam outlet 9, which can reduce the flow rate of the steam and alleviate the overflowing effect to a certain extent. Subsequently, most or all of the steam will flow along the steam outlet chamber 19 and exit at the rear end of the steam outlet chamber 19 through the steam outlet 28 of the steam valve cover 26 (of course, with the steam valve seat 1 and the steam valve cover 26 in the assembled state).
Further, the bottom surface 20 of the steam exhaust chamber 19 extends obliquely towards the steam outlet 9 based on the same backflow effect, so that the steam outlet 9 is formed as the lowest part of the bottom surface 20 of the steam exhaust chamber 19. For example, the bottom surfaces 20 around the steam outlet 9 may be inclined toward the steam outlet 9 as a whole, and the bottom surfaces 20 around the steam outlet 9 are arcuately connected to each other to form a funnel-like shape; alternatively, as shown in fig. 1, the bottom surface 20 is divided into two parts by a lowest boundary line 33, wherein the two parts of the bottom surface 20 extend obliquely toward the lowest boundary line 33, respectively, so as to form a V-shaped groove or a U-shaped groove at the lowest boundary line 33, and the V-shaped groove or the U-shaped groove is communicated with the steam outlet 9, so that the liquid in the steam discharge chamber 19 can timely flow back to the steam outlet 9 and flow back from the return hole 10 near the steam outlet 9.
Further, in order to extend the flow path of the steam discharged from the steam outlet 9, it is preferable that, as shown in fig. 1, a drainage baffle 21 is disposed on a bottom surface 20 of the steam discharge chamber 19, one end of the drainage baffle 21 is connected to extend toward a side chamber wall 22 of the steam discharge chamber 19, and the other end of the drainage baffle 21 extends close to one side edge of the steam outlet 9 and maintains a gap 23 with the side edge, that is, due to the blocking effect of the drainage baffle 21, the steam discharged from the steam outlet 9 is not directly discharged from a steam discharge port 28 on a steam valve cover 26, but most of the steam flows through a large part of the steam discharge chamber 19 and is then discharged from the steam discharge port 28, of course, due to the existence of the gap 23, a small part of the steam discharged from the steam outlet 9 directly passes through the gap 23 and is then discharged from the steam discharge port 28, and at the same time, the returned liquid can flow back to the. For example, in the graphical interface shown in fig. 1, the other end of the flow guide baffle 21 maintains a gap 23 with the right side edge of the steam outlet 9, and at this time, when the steam valve cover 26 is assembled, the steam outlet 28 on the steam valve cover 26 is located on the upper space of the steam outlet cavity 19, so that most of the steam discharged from the steam outlet 9 flows leftwards first, flows upwards under the guidance of the inner circumferential surface of the steam outlet cavity 19, then flows rightwards, then flows downwards and is discharged from the steam outlet 28, and in the process, the bent part of the inner circumferential surface of the steam outlet cavity 19 can further break the bubbles of the steam, thereby improving the anti-overflow effect.
In addition, in order to facilitate the assembly of the steam valve having the steam valve seat, it is preferable that a fixing frame 25 for assembling and positioning the steam valve seat is formed on the lower surface 24 of the plate body 2, as shown in fig. 3 and 4, wherein the steam inlet 8 is located in the fixing frame 25. Of course, the shape of the fixing frame 25 is preferably adapted to the shape of the drainage housing 3, and may be, for example, a rectangular frame.
