Description

TECHNICAL FIELD

[0001] The utility model relates to a runner type venturi carbon neutralization steam trap, specifically, the utility model aims at separating and discharging the condensed water generated in the high-temperature, high-pressure steam pipeline, thereby improving the power generation efficiency and heat recovery efficiency. The utility model also has the function of efficiently cleaning steam, and can dynamically adjust the steam aperture according to the steam pressure and discharge amount, thereby realizing the accurate and continuous discharge of condensed water. In this process, the utility model can stabilize the steam pressure and maintain constant temperature. The steam trap of this design is a runner type structure and has carbon neutralization performance. BACKGROUND

[0002] Generally, in industrial facilities such as power plants, steam delivery systems are commonly installed with steam traps on the pipelines. This device is mainly used to discharge condensed water generated during constant pressure steam supply due to external low temperature influence.

[0003] The steam trap installed on the steam pipeline is essentially an intelligent automatic control valve, and its core function is to effectively separate and discharge condensed water during steam delivery, while preventing steam leakage.

[0004] Therefore, the steam trap on the steam pipeline must have the function of removing air and non-condensable gases to ensure the stability of the entire system performance and achieve energy saving effect.

[0005] If the steam trap of the steam pipeline leaks steam, it will cause the loss of heat carried by the steam, resulting in energy waste. At the same time, the pressure in the condensed water recovery pipe will rise, thereby affecting the pressure balance of other steam traps in the connecting pipeline, ultimately leading to the decline of the entire system efficiency.

[0006] In addition, if the steam trap does not work properly, it may also cause water hammer phenomenon, which not only damages the pipeline system, but also greatly shortens the service life of the valve and the main pipeline.

[0007] At present, the steam trap is mainly used to automatically discharge condensed water in the pipeline, and common designs include floating ball type, disc type, bimetallic strip type, bucket type and orifice type.

[0008] Among the above-mentioned various types of steam traps, the floating ball type steam trap uses the density difference between steam and condensed water to discharge condensed water, although it is not easily affected by pressure and flow fluctuations, but it is easily damaged by scale deposition.

[0009] The working principle of the disc type steam trap is that when condensed water accumulates in the trap, the temperature inside the valve decreases, causing the pressure in the pressure chamber to drop, thereby causing the disc to rise and discharge condensed water.

[0010] A bimetallic strip type steam trap is a valve that opens when condensate accumulates in the trap, lowering the temperature inside the valve, and causing the bimetallic strip to deform, opening the ball valve and allowing the condensate to drain.

[0011] The bimetallic strip in a bimetallic strip type steam trap is made of two metals with different thermal expansion rates that are bonded together and will bend due to temperature changes.

[0012] A float bucket type steam trap works on the principle of buoyancy. Under normal conditions, the float bucket rises, causing the drain valve to close. When inlet condensate flows in and accumulates in the float bucket, the float bucket sinks, causing the drain valve connected to it to open, and the accumulated condensate to be drained under the action of steam pressure.

[0013] The principle of an orifice type steam trap is to prevent steam leakage by maintaining the drained condensate occupying the small holes of the orifice.

[0014] The orifice type steam trap has the advantages of minimizing steam leakage, not requiring an operating device, having a small heat dissipation area, and having a high heat transfer efficiency to the heating body, making it the most widely used and economical and efficient type.

[0015] However, the orifice type steam trap of the conventional art is always in an open state under the action of the pressure difference between steam and condensate, and can be frequently opened unnecessarily, causing valve wear and thus shortening the service life of the steam trap and generating noise.

[0016] When condensate accumulates in the system at a rate exceeding the expected rate, a backflow phenomenon to the main pipe can occur, causing a water hammer phenomenon, which can seriously affect the service life of the valve and the main pipe.

[0017] Patent Document 1 (Republic of Korea Registered Patent Gazette No. 10-2181147, registered on November 16, 2020) discloses a steam trap having a Venturi nozzle type, orifice nozzle type, or tunnel structure resistance pipe, using a rotary adjustment mechanism to adjust the condensate discharge amount by changing the height difference between the drain port of the steam trap drain low portion and the external drain port of the system.

[0018] Although the nozzle type steam trap of Patent Document 1 can adjust the condensate discharge amount without replacing the core components such as the orifice nozzle, Venturi nozzle, and tunnel structure resistance pipe when the steam usage amount or working pressure changes, it cannot automatically adjust the steam flow according to changes in the ambient temperature, and cannot control the size of the steam hole through a disassembly-free, tool intervention method during adjustment, thus causing fluctuations in steam pressure and temperature due to changes in the external temperature.

[0019] Patent Document 2 (Republic of Korea Registered Patent Gazette No. 10-2681773, Registered on July 1, 2024) proposes an improved rotating wheel type Venturi carbon neutralization steam trap, which includes: a valve body assembly installed between a steam supply pipeline and a discharge pipeline, which integrates a steam trap and a control valve; an intelligent adjustment system provided on the valve body, which can be adjusted in real time according to the steam pressure and discharge amount to ensure the stability of the system pressure and temperature; and a discharge device specially used for condensate water of the trap body. The design controls the steam discharge amount through the precision nozzle of the trap part, realizes the continuous and stable discharge of condensate water, and ensures the constant system temperature and pressure.

[0020] The plug type Venturi carbon neutralization steam trap related by Patent Document 2 is an invention applied earlier by the applicant, which has the effect of adjusting the condensate discharge amount according to the field environment, i.e. the invention can control the steam pressure and condensate discharge amount outside the steam trap of the Venturi hole using tools.

[0021] However, the steam trap part of the plug type Venturi carbon neutralization steam trap related by Patent Document 2 is composed of multiple fittings including a nozzle, a rotating handle, a combination, and a rotating cover, so there is a problem that the fittings of the steam trap part are complicated to make and have high production cost.

[0054] Main body 100 is the component installed on the steam pipeline, the overall shape is that the inclined pipe body is integrally formed in the lower central part of the horizontal pipe body, and the connecting part 110 of the steam trap component 220 is equipped in the central part of the front end of the horizontal pipe body.

[0055] The structure of the main body 100 is such that steam flows in from one side of the horizontal pipe body and flows out from the other side.

[0056] A connection part 110 is formed in the center of the front end of the main body 100, and a rotating cover 250 of a steam drain part 200, which will be described later, is installed by screwing.

[0057] A protruding surface 111 is formed at the front end of the connection part 110, and is used to install the rear end of a nozzle 220 of the steam drain part 200.

[0058] A main body steam hole 112 for supplying high-pressure steam flowing into the main body 100 and a condensate drain hole 113 for draining condensate treated by the steam drain part 200 are provided on the protruding surface 111.

[0059] A connection part gasket 114 is installed on the connection part 110, and is used to improve the sealing property when the rotating cover 250 is screwed and to prevent the connection part 110 from being separated from the rotating cover 250.

[0060] The steam drain part 200 is installed on the connection part 110 of the main body 100, and functions to adjust the steam pressure according to the steam pressure and discharge amount, to maintain the steam pressure and temperature constant, thereby facilitating steam supply.

[0061] The steam drain part 200 includes the nozzle 220, the rotating cover 250, a nameplate 260, and a cover ring 270.

[0062] In the rotating wheel type Venturi carbon neutral steam drain valve according to the present application, condensate generated by initially introduced steam remains on the inside of the rotating cover 250, and when newly generated condensate exceeds a predetermined water level, it is drained through the condensate drain hole 113 of the connection part 110.

[0063] The nozzle 220 is a part for adjusting the amount of steam discharged to the main body steam hole 112 of the connection part 110 of the main body 100, and can be rotated left and right in front of the connection part 110 of the main body 100.

[0064] The nozzle 220 has a form in which a pressing circular plate 222 is provided in front of an adjusting circular plate 221 attached to the protruding surface 111 of the connection part 110, and an adjusting shaft 223 is provided in front of the pressing circular plate 222 and is inserted into and connected to a coupling hole 251 of the rotating cover 250, which will be described later.

[0065] A plurality of nozzle steam holes 221-1 are formed in a circular arrangement on the adjusting circular plate 221 of the nozzle 220 at positions corresponding to the main body steam hole 112, to adjust the amount of steam supplied to the main body steam hole 112 of the protruding surface 111 of the connection part 110.

[0066] The plurality of nozzle steam holes 221-1 formed on the adjusting circular plate 221 are arranged in a clockwise direction or an anticlockwise direction in order of diameter from small to large.

[0067] In the illustrated embodiment, the nozzle steam holes 221-1 of the adjusting circular plate 221 are five in number, but the number of the nozzle steam holes 221-1 formed on the adjusting circular plate 221 can be a predictable number, such as one, four, six, eight, etc., in the rotary-type Venturi carbon neutralization steam trap to which the present application relates.

[0068] The pressing circular plate 222 is a part that moves the nozzle 220 in the direction of the connecting portion 110 during the process of screwing the rotating cover 250 into the connecting portion 110, thereby stably making the adjusting circular plate 221 of the nozzle 220 adhere to the portion of the protruding surface 111 of the connecting portion 110, and has a diameter slightly smaller than that of the adjusting circular plate 221.

[0069] The adjusting shaft 223 is a part for connecting a wrench to rotate the nozzle 220 left and right, and has a wrench groove 223-1 and an indication groove 223-2 on the end surface exposed through the coupling hole 251 of the rotating cover 250.

[0070] The elastic compression washer 224 is inserted and installed on the adjusting shaft 223, and exerts an appropriate elastic pressure on the pressing circular plate 222 when the rotating cover 250 is threadedly connected to the connecting portion 110, thereby ensuring the stability and sealing of the assembly.

[0071] The compression washer 224 has a disc shape with a central portion protruding forward to provide an elastic force.

[0072] The reference numeral 225, which is not illustrated in the drawing, is an O-ring for sealing.

[0073] The rotating cover 250 is installed in front of the connecting portion 110 of the main body 100, and serves to compress and support the nozzle 220, and is threadedly connected to the connecting portion 110 of the main body 100.

[0074] The rotating cover 250 has a cylindrical shape with a sealed front end, and has a coupling hole 251 for inserting the adjusting shaft 223 of the nozzle 220 at the front end, and an external thread for threadedly connecting the cover ring 270 at the outer peripheral end.

[0075] The nameplate 260 serves to display the amount of steam corresponding to the steam amount adjustment position of the nozzle 220, and has a circular plate shape with a through hole 261 for passing the end portion of the adjusting shaft 223 of the nozzle 220.

[0076] The nameplate 260 has a steam amount diagram 262 for adjusting the amount of steam supplied from the main body 100, and a steam hole diagram 263 formed on the adjusting circular plate 221 to confirm the position of the nozzle steam hole 221-1.

[0077] The cover ring 270 is a part fixedly installed in the position of the nameplate 260 in front of the rotary cover 250, and is located at the front end of the rotary cover 250.

[0078] The cover ring 270 is annular to confirm the steam amount diagram 262 and the steam hole diagram 263 formed on the nameplate 260 and is screw-fastened to the rotary cover 250.

[0079] In the runner type Venturi carbon neutralization steam trap, the steam flowing into the horizontal pipe body of the main body 100 through the main body steam hole 112 of the connecting part 110 flows into the inside of the rotary cover 250, at this time, the nozzle 220 is rotated clockwise or counterclockwise by using a wrench or the like, and the amount of steam flowing into the inside of the rotary cover 250 can be adjusted.

[0080] Specifically, the user can adjust the amount of steam flowing into the inside of the rotary cover 250 by inserting a tool into the wrench groove 223-1 at the front end of the nozzle 220 adjusting shaft 223 exposed from the combination hole 251 of the rotary cover 250, and rotating the nozzle 220 clockwise or counterclockwise while referring to the steam amount diagram 262 and the steam hole diagram 263 on the nameplate 260.

[0081] When the nozzle 220 is rotated clockwise or counterclockwise by using a tool, the nozzle steam hole 221-1 on the adjusting circular plate 221 corresponding to the main body steam hole 112 of the connecting part 110 can be changed. If the nozzle steam hole 221-1 with a diameter smaller than the originally set nozzle steam hole 221-1 corresponds to the main body steam hole 112 of the connecting part 110, the amount of steam flowing into the inside of the rotary cover 250 is reduced, and if the nozzle steam hole 221-1 with a diameter larger than the originally set nozzle steam hole 221-1 corresponds to the main body steam hole 112 of the connecting part 110, the amount of steam flowing into the inside of the rotary cover 250 is increased.

[0082] The condensed water generated by the steam flowing into the inside of the rotary cover 250 through the nozzle steam hole 221-1 of the adjusting circular plate 221 is discharged through the condensed water discharge hole 113 of the connecting part 110 and is supplied to the valve part 300 through the main body 100.

[0083] As described above, in the runner type Venturi carbon neutralization steam trap, the user can adjust the amount of steam flowing into the inside of the rotary cover 250 according to the situation on the spot, and thus the appropriate amount of condensed water is discharged to maintain a certain temperature.

[0084] Figure 6 is a front view of the nameplate of the runner type Venturi carbon neutralization steam trap according to the present application; Figure 7 is a front view of the valve part structure of the runner type Venturi carbon neutralization steam trap according to the present application; Figure 8It is the valve part foreign matter removing component structure sectional view of the runner type Venturi carbon neutralization steam trap of the utility model; Figure 9 It is the part side view of the runner type Venturi carbon neutralization steam trap in the utility model in combination with the valve part screen cover foreign matter removing component; Figure 10 It is the screen cover structure sectional view of the runner type Venturi carbon neutralization steam trap of the utility model;

[0085] Valve part 300 is the part that can discharge the condensate water condensed in main body 100, and it is arranged in the inclined pipe body of main body 100 to discharge the condensate water generated by adjusting the steam supply amount from steam trap part 200.

[0086] Valve part 300 is composed of screen cover 310, plug 320 and foreign matter removing component 330.

[0087] Screen cover 310 is inserted into the inside of the inclined pipe body, that is, the inside of cap connecting pipe 120 of main body 100, and is screw-connected with it.

[0088] A fastening hole 311 with screw thread is formed in the center of screen cover 310, and plug 320 is connected in the fastening hole.

[0089] The inside of screen cover 310 has a combination groove 312-1 capable of combining foreign matter removing component 330, and forms a net combination body 312, a plurality of foreign matter removing holes 312-2 are formed in the combination groove 312-1 on net combination body 312, so as to remove the foreign matter contained in the steam filtered by foreign matter removing component 310 by using high-pressure steam.

[0090] Foreign matter removing holes 312-2 are preferably formed as circular or elliptical long holes, but can also be formed as various other shapes.

[0091] A cover gasket 313 made of metal is arranged in screen cover 310, and cover gasket 313 has elastic force to prevent cap connecting pipe 120 and screen cover 310 from being separated in the combined state.

[0092] In addition, cover gasket 313 maintains the sealing property between cap connecting pipe 120 and screen cover 310 by the elastic force, so as to prevent steam leakage.

[0093] Plug 320 is arranged in fastening hole 311 to discharge the foreign matter filtered by foreign matter removing component 330 controlled by opening and closing valve, and to discharge the condensate water generated by the steam flowing from main body 100.

[0094] In addition, in order to remove the impurities in the steam flowing from main body 100, impurity removing assembly 330 is installed on net rack body 312 of filter cap 320, which is located in the inside of cap connecting pipe 120.

[0095] The impurity removal assembly 330 is composed of a first filter screen 331, a second filter screen 332, and a screen rack fixing body 333.

[0096] The first filter screen 331 is installed inside the connecting groove 312-1 formed on the screen rack body 312 of the filter cap 310 and is located inside the cap connecting pipe 120.

[0097] The second filter screen 332 is installed inside the connecting groove 312-1 formed on the screen rack body 312 at a certain distance from the first filter screen 331 and is located inside the cap connecting pipe 120.

[0098] The mesh of the first filter screen 331 is larger than that of the second filter screen 332, and the mesh of the second filter screen 332 is relatively small, so that impurities can be removed step by step through the first filter screen 331 and the second filter screen 332.

[0099] The first filter screen 331 and the second filter screen 332 ensure that the steam flowing to the steam drain 200 has been filtered by impurities.

[0100] The screen rack fixing body 333 has a circular structure and is provided with a screen rack fixing protrusion 333-1 on one side, and the protrusion is provided with a screen rack fixing groove 333-2. The first filter screen 331 is installed on the inner side of the screen rack fixing protrusion 333-1, and the second filter screen 332 is installed in the screen rack fixing groove 333-2.

[0101] The screen fixing body 333 is inserted into the inner side of the cap connecting pipe 120 in a state of being provided with the first filter screen 331 and the second filter screen 332, so that the first filter screen 331 and the second filter screen 332 are easily installed, and the steam drain 200 is easily assembled, thereby improving the convenience of production.

[0102] The rotating type Venturi carbon neutral steam drain valve disclosed by the utility model can set the pressure of steam and the discharge amount of condensed water from the outside, so that the discharge amount of condensed water can be easily adjusted according to the site environment.

[0103] In addition, while the steam is effectively cleaned, the position of the nozzle steam hole 221-1 can be adjusted according to the steam pressure and the discharge amount, the change of the condensed water can be coped with while the steam pressure and the temperature change do not occur, and therefore the efficiency of steam supply is improved.

[0104] In addition, the diameter of the nozzle steam hole 221-1 gradually increases from the outside of the rotating type Venturi hole steam drain valve which can adjust the amount of condensed water from the outside by using the steam pressure, so that the rapid discharge of the condensed water is ensured.

[0105] The rotating wheel type Venturi carbon neutralization steam trap is capable of discharging condensate water by using the valve part 300 which can adjust the condensate water amount from outside, so that the smooth discharge of condensate water can be ensured even if a large amount of condensate water is generated below a certain temperature.
