Detailed Description
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
The first embodiment is as follows:
the embodiment discloses a steam valve assembly and a steam heating device comprising the same. As shown in fig. 2 and 3, the steam valve assembly includes a valve cover 1, a valve seat 2 and bubble breaking fan blades 3, the bubble breaking fan blades 3 are disposed in a steam cavity 4 enclosed by the valve cover 1 and the valve seat 2, the bubble breaking fan blades 3 include a rotating shaft 31 and blades 32 disposed on the outer side wall of the rotating shaft 31, the rotating shaft 31 is vertically disposed between the valve cover 1 and the valve seat 2, and the blades 32 are disposed in an inclined manner relative to the axis of the rotating shaft 31 and are twisted to a certain degree. In order to prevent steam from leaking from the periphery of the steam valve assembly, a sealing ring 6 is provided between the valve cover 1 and the valve seat 2.
The bubble breaking fan blades 3 are vertically arranged, and when steam with liquid is blown to the lower surfaces of the inclined blades 32, the blades 32 are pushed to move transversely, so that bubbles in the steam are effectively broken, the steam is prevented from flowing too fast, and meanwhile, too large resistance is not generated to steam flow; the steam without the viscous liquid can flow freely between the blades 32, and the pressure in the steam heating device is always in a safe range.
As shown in fig. 2 to 7, the valve seat 2 is provided with a return hole 21, and the return pad 5 is mounted in the return hole 21. When the steam pressure is lower than the set value, the backflow pad 5 sinks due to its own weight and the pressure applied thereto by the bubble breaking blades 3, and opens the backflow hole 21 (as shown in fig. 6, the arrow curve in the figure indicates the gas flow direction), and the liquid droplets can flow back into the steam heating device through the backflow hole 21. When the steam pressure is greater than or equal to the set value, the force of the steam is greater than the gravity of the backflow pad 5, and the blades 32 of the bubble breaking fan blades 3 are blown by the steam to be lifted upwards, so that the backflow pad 5 floats upwards until the backflow hole 21 is completely shielded (as shown in fig. 7, a straight line with an arrow in the figure indicates the flow direction of the steam), and the high-pressure steam with liquid is prevented from directly rushing out of the backflow hole 21.
As shown by the dotted lines with arrows in fig. 4 and 5, the flow path of the steam in the exhaust state is shown, and the solid curve with arrows indicates the rotation direction of the bubble-breaking fan blades 3. In the steam chamber 4, the line with the arrow is the dropping direction of the condensed liquid droplets of the viscous liquid, and the steam is discharged through the air outlet 11 on the valve cover 1.
In order to avoid that the steam directly breaks the blades 32 of the fan blades 3, a plurality of blocking ribs are arranged on the valve seat 2 along the air inlet channel 24, or the blocking ribs are enclosed to form the air inlet channel 24. Specifically, a first valve seat rib 241 is arranged on the bottom surface of the valve seat 2, and the first valve seat rib 241 is located at a position of the air inlet 23 close to the edge and used for blocking the liquid-carrying vapor rushing to the position; when the liquid-carrying vapor enters the air inlet channel 24 through the air inlet 23, the liquid-carrying vapor may sequentially strike the second rib 242 and the third rib 243 of the valve seat, and then enter the vapor chamber 4 along the space between the two oppositely arranged fourth ribs 244 of the valve seat.
As can be seen from fig. 4, the second rib 242 is perpendicular to the flow direction of the liquid-carrying vapor entering the air inlet 23, and the third rib 243 is substantially perpendicular to the flow direction of the liquid-carrying vapor after striking the second rib 242. The third rib 243 of valve seat keeps off except stopping taking liquid steam directly towards, the third rib 243 of valve seat has still reduced the sectional area at intake passage 24 here, make take liquid steam slope to rush into intake passage 24's back end, and flow along the lower surface of slope, it is oblique downward flow when guaranteeing to take liquid steam to get into steam chamber 4, avoid directly towards blade 32, reduce the probability that the viscid liquid adheres to on blade 32 or gets into the upper and lower both ends of pivot 31, avoid pivot 31 because of the adhesion of viscid liquid to be difficult to rotate, even the jamming.
Referring to fig. 5, when the liquid-carrying vapor flows to the position D, a part of the air flow will impact the first rib 241 of the valve seat, and the liquid-carrying vapor condenses into liquid drops on the cavity wall and flows back into the vapor heating device; when the liquid-carrying steam flows to the position E, the air flow impacts the second rib 242, the third rib 243 and the inner side of the cavity wall of the valve seat, and most of solid substances such as rice grains carried in the liquid-carrying steam are blocked at the position; when the liquid-carrying steam flows to the position F, the liquid-carrying steam enters the steam cavity 4 under the blocking of the fourth blocking ribs 244 of the two valve seats, and cannot directly impact the air outlet 11.
After entering the steam chamber 4, the high-temperature and high-pressure steam with liquid blows the blades 32, and the inclined blades 32 simultaneously generate axial upward movement and circumferential rotation. The rotation of the blades 32 reduces ambient temperature, slows down airflow, consumes energy, and simultaneously breaks or breaks bubbles generated from the viscous liquid to prevent the generation of new bubbles. With the rotation of the blades 32 and the centrifugal force of the blades 32, the viscous liquid hits the inner wall of the steam chamber 4, and is rapidly condensed into liquid droplets. The liquid drops drop to the bottom of the steam cavity 4 and can flow back to the steam heating device when the return hole 21 is opened. The common steam without the viscous liquid is discharged after passing through the communication gap 251 and the air outlet 11 in sequence.
After the boiling process in the steam heating device is finished, the bubble breaking fan blades 3 sink to the initial position, the backflow pad 5 is pushed to move downwards, the backflow hole 21 is opened, and backflow of liquid drops is accelerated.
In order to realize the linkage of the bubble breaking fan blades 3 and the backflow pad 5, as shown in fig. 2, 8 and 9, the bottoms of the rotating shafts 31 of the bubble breaking fan blades 3 are installed on the installation part 22 of the valve seat 2, and the backflow pad 5 is installed on the installation part 22; when the bubble breaking fan blade 3 is pressed down, the bottom end of the rotating shaft 31 abuts against the top end of the backflow pad 5 and can extrude the backflow pad 5 to move downwards.
As shown in fig. 10 to 13, the top of the rotating shaft 31 of the bubble-breaking fan blade 3 is a tubular structure, and a plurality of rotating shaft protrusions 33 are disposed on the top surface of the tubular structure. After the installation, the top of the rotating shaft 31 abuts against the inner surface of the valve cover 1, namely the rotating shaft salient point 33 abuts against the inner surface of the valve cover 1, and the contact structure of the point and the surface reduces the friction force and avoids the clamping stagnation in the rotating process of the bubble breaking fan blades 3; in addition, gaps are formed among the rotating shaft salient points 33, so that the inside and the outside of the tubular structure at the top of the rotating shaft 31 are communicated, the blockage of sticky liquid between the top of the rotating shaft 31 and the inner surface of the valve cover 1 is avoided, and the problem of rotating shaft clamping stagnation in the existing structure is further solved.
The bottom of the rotating shaft 31 of the bubble breaking fan blade 3 is a columnar structure, and the columnar structure is inserted into the mounting part 22 on the tubular valve seat 2. In order to limit the position of the rotating shaft 31 and prevent the rotating shaft 31 from being excessively inserted into the mounting portion 22, a protruding edge 34 may be provided at a proper position of the bottom of the rotating shaft 31, or the rotating shaft 31 may be contracted in diameter at a proper position to form a step-shaped structure, and the top surface of the mounting portion 22 abuts against the lower surface of the protruding edge 34 or the lower surface of the step-shaped structure to accurately limit the rotating shaft 31.
In order to better link the backflow pad 5, a backflow pad connecting cavity 35 is formed inside the bottom end of the rotating shaft 31, and a corresponding structure on the backflow pad 5 can be inserted into the backflow pad connecting cavity 35, so that dislocation between the backflow pad and the backflow pad 5 due to up-and-down movement of the bubble breaking fan blades 3 is avoided.
At least two layers of blades 32 are arranged on the outer side wall of the rotating shaft 31 of the bubble breaking fan blade 3, and the blades 32 in different layers are arranged in a staggered mode. The term "offset" is used herein to mean that the blades 32 of different layers do not completely overlap. Because of the area issues, there may actually be some overlap between the different layers of blades 32.
In order to better convert the impact force of the liquid-carrying steam into the movement thrust of the bubble breaking fan blade 3 and increase the contact area of the liquid-carrying steam and the blades 32, the blades 32 are twisted into a structure similar to a spoon, the inner surface of the spoon is downward, and the liquid-carrying steam can contact the lower side surfaces of the blades 32 more.
Broken bubble flabellum 3 is vertically installed between valve gap 1 and disk seat 2, easy dismounting, sound construction. The upper end face and the lower end face of the rotating shaft 31 can be planes, so that the processing is convenient and the cost is low; and a chamfer can be formed at the edge, so that the assembly and disassembly are smoother.
As shown in fig. 14 to 16, two air inlets 23 are provided on the valve seat 2, and the air inlets 23 communicate with the steam chamber 4. Correspondingly, two air inlet channels 24 are arranged on the valve seat 2, each air inlet channel 24 at least comprises a turn, the displacement of the steam with liquid in unit time is relatively large, and the efficiency is higher. The included angle between the two air inlet channels 24 is less than 180 degrees, so that two strands of liquid-carrying steam in the steam cavity 4 are prevented from directly rushing towards each other, and the liquid-carrying steam in one air inlet channel 24 is prevented from directly rushing into the other air inlet channel 24.
An arc valve seat blocking rib 25 is arranged between the two air inlet channels 24 and used for blocking liquid-carrying steam in the steam cavity 4 from rushing out from between the two air inlet channels 24, and a communication gap 251 is arranged on the valve seat blocking rib 25 in order to enable common steam with sticky liquid removed to normally vent. In order to better block the liquid-carrying vapor, as shown in fig. 14, two layers of valve seat blocking ribs 25 are arranged on the valve seat 2 in the front and back direction, and the communication gaps 251 on the two layers of valve seat blocking ribs 25 are arranged in a staggered manner, so that even if part of the liquid-carrying vapor rushes through the communication gaps 251 of the first layer of valve seat blocking ribs 25, the liquid-carrying vapor can be blocked by the valve seat blocking ribs 25 on the second layer.
The top surface of the mounting portion 22 is provided with mounting portion bumps 221 to prevent the rotation shaft 31 from being stuck. In order to accelerate the return of the liquid droplets, a flow-guiding bevel 26 is also provided on the bottom surface of the valve seat 2.
As shown in fig. 17 and 18, the valve cover 1 is provided with an air outlet 11, and the air outlet 11 is communicated with the steam cavity 4. The valve cover 1 is provided with a valve cover rib 12, as shown in fig. 8 and 9, after the valve cover 1 and the valve seat 2 are buckled, the steam cavity 4 is divided into an inner cavity and an outer cavity by the valve cover rib 12 and the valve seat rib 25, and the inner cavity and the outer cavity are communicated through a communication gap 251. The bubble breaking fan blades 3 are positioned in the inner cavity, vapor with liquid flows only in the inner cavity, and common vapor without viscous liquid can enter the outer cavity after passing through the communication gap 251 and then is discharged from the air outlet 11.
When the cover is opened, the gas outlet 11 and the steam cavity 4 have certain capacity, so that partial accumulated liquid can be accommodated, and meanwhile, part of accumulated liquid is blocked by the valve seat blocking rib 25, so that the accumulated liquid cannot enter the outer cavity, and the accumulated liquid is prevented from flowing onto the working table.
The valve cover 1 is provided with the fixing pin 13 which can be inserted into the tubular structure at the top of the rotating shaft 31 of the bubble breaking fan blade 3, so that the fixing effect on the top of the rotating shaft 31 is better.
As shown in fig. 19, the reflow pad 5 includes a spacer 51, a stopper 52, and a shaft connecting portion 53. The spacer 51 is made of a flexible material, such as rubber, plastic; the area of the gasket 51 is larger than the total area of the position of the reflux hole 21, so that the reflux hole 21 can be completely shielded after the gasket 51 is lifted, and the steam with liquid directly enters the steam cavity 4 from the reflux hole 21.
The limiting portion 52 is a frustum-shaped structure, and the structure with a small top and a large bottom facilitates installation and prevents easy separation from the installation portion 22 of the valve seat 2 due to pressing down after installation. A certain distance is left between the bottom surface of the limiting part 52 and the gasket 51 for accommodating the wall thickness of the mounting part 22, and a sufficient space is left for the up-and-down movement of the reflow pad 5.
The shaft connecting portion 53 is a cylindrical structure and is inserted into the reflow pad connecting cavity 35 at the bottom end of the shaft 31 after being installed.
Example two:
the present embodiment discloses a steam valve assembly and a steam heating device including the same, which have substantially the same structure as the first embodiment. Except that, as shown in fig. 20, the inner surface of the valve cap 1 is provided with a fixing sleeve 14 instead of the fixing pin 13 of the first embodiment. Accordingly, as shown in fig. 21 and 22, a columnar structure 36 is formed at the top of the rotating shaft 31 of the bubble-breaking fan blade 3. As shown in fig. 23, columnar structure 36 is inserted into fixing sleeve 14 to mount bubble-breaking fan blade 3.
In fig. 22, the lower portion of the rotating shaft 31 is contracted in diameter at a proper position to form a stepped structure, and the top surface of the mounting portion 22 of the valve seat 2 abuts against the lower surface of the stepped structure, so that the rotating shaft 31 can be accurately limited.
The structure of the valve seat 2 may be modified as shown in fig. 24, and the valve seat 2 includes only one inlet port 23 and, accordingly, only one inlet passage 24, to increase the condensation rate of the viscous liquid by reducing the flow rate of the vapor.
It should be noted that the foregoing is only a preferred embodiment of the present invention and the technical principles employed. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention.
