Description

Technical Field

[0001] This invention belongs to the technical field of desuperheating and pressure reducing valves, and particularly relates to an atomizing nozzle type desuperheating and pressure reducing valve. Background Technology

[0002] The desuperheating and pressure-reducing valve is a type of valve used to regulate the flow rate of a medium and reduce its pressure and temperature. It is widely used in various industries such as thermal power plants, district heating, food industry, and petrochemical industry. This valve regulates the flow rate by controlling the opening degree of the opening and closing parts in the valve body, and sprays cooling water into the valve body or downstream of the valve to reduce the temperature. It integrates the three functions of pressure reduction, desuperheating, and noise reduction. The integrated desuperheating and pressure-reducing valve performs desuperheating and pressure reduction in the same valve, reducing the installation space.

[0003] In the existing technology (patent application CN213855172U, entitled "A Nebulizer-Type De-icing and Pressure-Reducing Valve"), disassembly is convenient, and adjustments can be made as needed, thus improving the cooling effect of the device. However, in implementing this technical solution, at least the following problems were found in the existing technology: When reducing the temperature and pressure of a fluid medium, a desuperheating and pressure reducing valve is used. However, most desuperheating and pressure reducing valves currently in use directly achieve the effect of reducing the temperature of the fluid medium inside the valve and passing through it through an atomizing nozzle on an embedded single refrigeration pipe. This is prone to uneven cooling, the cold source cannot fully reach the inside of the valve body, and it is not easy to make sufficient cooling contact with the fluid medium passing through, thus reducing the cooling effect of the fluid medium. Summary of the Invention

[0004] This application aims to at least solve the technical problem in the prior art that, without relying on inlet and outlet turbulence for pressure relief, the combination of swirling flow and cold conduction cannot achieve a uniform and comprehensive cooling and pressure reduction effect on the valve body and the fluid medium it passes through. To this end, this application proposes an atomizing nozzle type cooling and pressure reducing valve.

[0005] To achieve the above objectives, the specific technical solution of the present invention is as follows: A type of atomizing nozzle de-temperature and pressure reducing valve includes a valve body. A valve core is threadedly embedded at the top of the valve body. The valve core is electrically controlled to facilitate automatic opening and closing of the valve cavity within the valve body. The threaded embedding of the valve core and the valve body facilitates quick screwing and disassembly of the valve core. The inlet end of the valve body is connected to a feed pipe, and the outlet end of the valve body is connected to a discharge pipe. Both the feed pipe and the discharge pipe have external threads at their outer ends to facilitate threaded connection between the feed pipe and the discharge pipe and the external pipeline. Furthermore, the valve body and the feed pipe are sealed by an inlet plug thread, which facilitates quick disassembly and assembly of the feed pipe on the valve body. The valve body and the discharge pipe are sealed by an outlet plug thread, which facilitates quick disassembly and assembly of the discharge pipe on the valve body. A temperature and pressure gauge is threadedly embedded on the side of the valve body near the valve core to monitor the temperature and pressure inside the valve body in real time, ensuring that the temperature and pressure generated by the fluid medium inside the valve body are within the normal monitoring threshold. Both the inlet and outlet ends of the valve body are provided with flow disturbance components for flow disturbance cooperation between the feed pipe and the discharge pipe, and the flow disturbance components include a skeleton embedded in the inlet and outlet ends of the valve body. The bottom end of the valve body is threadedly connected to a valve seat, and the bottom of the valve seat is fixed with a cover. The cover contains a rotating component and a cold conduction component that cooperate with the cooling of the valve body.

[0006] Preferably, the flow-disrupting component further includes a flow-equalizing mesh embedded in the frame. The frame provides fixed support for the flow-equalizing mesh, which in turn equalizes the flow and stabilizes the pressure of the fluid medium flowing into and out of the valve body. The flow-equalizing mesh is distributed in a triangular equidistant manner along the horizontal axis of the frame. A rotating hole is provided in the middle of the frame, and a hollow rotating shaft rotates within the rotating hole. This facilitates the stable rotation of the hollow rotating shaft on the frame. The fluid medium flowing into and out of the valve body can also flow through the channel within the hollow rotating shaft, preventing the fluid medium from flowing too fast and causing turbulence.

[0007] Preferably, a turbulence impeller is fitted onto the hollow rotating shaft. Under the flow impact force generated by the fluid medium in the valve body, the turbulence impeller is forced to drive the hollow rotating shaft. The shaft rotates within the rotating holes on the frame, following the flow direction of the fluid medium. This turbulence effect on the fluid medium flowing into and out of the valve body, and also provides pressure relief. The turbulence impeller has a hollow cavity communicating with the hollow rotating shaft. A scraper for cleaning the flow equalization net is fixed on the hollow rotating shaft. The scraper, which rotates with the turbulence impeller, scrapes and cleans the flow equalization net on the frame, preventing impurities in the fluid medium from adhering to the flow equalization net for a long time and clogging its mesh, thus reducing the frequency of replacement and cleaning of the flow equalization net. The scraper is distributed in a triangular equidistant manner along the transverse axis of the hollow rotating shaft.

[0008] Preferably, the rotating assembly includes a servo motor horizontally positioned outside the housing, and a main bevel gear is sleeved on the output shaft of the servo motor. A driven bevel gear meshes with the main bevel gear, and the servo motor drives the driven bevel gear to rotate through the main bevel gear.

[0009] Preferably, the bevel gear is fitted with an air distribution pipe, and the top end of the air distribution pipe is connected to an atomizing nozzle for cooling the valve body. The rotating bevel gear drives the air distribution pipe and the atomizing nozzle on it to make a swirling motion in the valve cavity of the valve body, which is beneficial to the subsequent swirling cooling operation of the cold source.

[0010] Preferably, the valve seat is embedded with a flow equalization shroud that rotates with the air distribution pipe, and the flow equalization shroud has a flow equalization window on its circumference. The top of the flow equalization shroud has a flow equalization port that communicates with the atomizing nozzle. This stabilizes the flow of the cold source distributed in the valve body, prevents turbulence from occurring in the valve body when the cold source is distributed, and facilitates the cooling operation of the fluid medium carrying heat.

[0011] Preferably, the cold conduction assembly includes a cold injection pipe on an external cold source pipeline, and the inner end of the cold injection pipe is connected to a pressure boosting angle pipe. Through the cold injection pipe and the pressure boosting angle pipe, the cold source in the external cold source pipeline is pressurized and injected into the air distribution pipe from the cold injection pipe through the pressure boosting angle pipe. The cold injection pipe and the pressure boosting angle pipe are sealed by a cold injection sealing plug thread. The cold injection sealing plug facilitates quick disassembly and assembly of the cold injection pipe on the pressure boosting angle pipe.

[0012] Preferably, the top end of the pressure-boosting angle tube is connected to a rotating end, and the rotating end has a connecting end that is connected to the air distribution pipe. The rotating end and the connecting end are in an interconnected state. Through the rotating end and the connecting end, not only can the rotation requirement of the air distribution pipe on the connecting end be met, but normal cold source delivery can also be carried out in the air distribution pipe.

[0013] Preferably, the gas distribution pipe has an opening groove on the circumference of the side near the flow equalization hood, and a conductive sleeve is fitted on the gas distribution pipe to conduct cold through the opening groove. Cooling fins that rotate with the flow equalization hood are fixed around the conductive sleeve. The cold source in the gas distribution pipe reaches the valve cavity in the valve body in sequence through the opening groove and the conductive sleeve. After passing through the cooling fins, a comprehensive and efficient cooling effect of the fluid medium is achieved, preventing uneven cooling of the fluid medium and the occurrence of large temperature differences.

[0014] Preferably, the valve body has bypass heads connected to both sides near the outlet end and the valve seat, and the outer end of the bypass head is connected to an interconnecting bend. Through the bypass head and the interconnecting bend, it is convenient to interconnect and release pressure and reduce temperature of the fluid medium and cold source in the valve cavity of the valve body, as well as the fluid medium and cold source in the area near the outlet end of the valve body. The bypass head and the interconnecting bend are sealed by a bypass plug thread. By turning the bypass plug clockwise and counterclockwise, the interconnecting bends on the two sets of bypass heads can be quickly disassembled and repaired.

[0015] The atomizing nozzle type desuperheating and pressure reducing valve of the present invention has the following advantages: 1. This atomizing nozzle type depressurizing and pressure reducing valve achieves a uniform flow and pressure relief effect on the fluid medium at the valve body inlet and outlet through the skeleton of the turbulence component and the flow equalization net. The turbulence impeller on the hollow rotating shaft at the rotating hole also achieves a turbulence and pressure relief effect on the fluid medium at the valve body inlet and outlet, thus achieving a bidirectional pressure reduction effect on the fluid medium at the valve body inlet and outlet. This avoids excessive pressure and turbulence during the flow of the fluid medium, and also provides pressure relief and temperature reduction protection for the valve body.

[0016] 2. This atomizing nozzle type de-cooling and pressure reducing valve uses a servo motor of a rotating component to drive the main bevel gear and the driven bevel gear to rotate. Through the air distribution pipe and its atomizing nozzle, the cold source is released into the valve body in a swirling manner, improving the overall coverage of the cold source in the valve body and forcing the cold source to fully contact the passing fluid medium, thereby achieving a uniform and comprehensive de-cooling effect.

[0017] 3. This atomizing nozzle type de-icing and pressure reducing valve provides a cold source supply to the valve body and the fluid medium passing through it through the cold injection pipe and the pressurizing angle pipe of the cold conduction component. Then, the cold source supplied in the pressurized air distribution pipe is conducted to the cooling fin area through the opening groove and the conduction sleeve, realizing the conduction and diffusion effect of the cold source, further increasing the de-icing range of the valve body and the fluid medium passing through it, and also enhancing its de-icing effect, making the de-icing more rapid and the effect better.

Detailed Implementation

[0021] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments: like Figures 1-11 As shown, an atomizing nozzle type de-heating and pressure reducing valve of the present invention includes a valve body 1, and a valve core 2 is threadedly embedded at the top of the valve body 1. The valve core 2 is electrically controlled for opening and closing. The valve core 2 is threadedly embedded in the valve body 1, which facilitates quick screwing and disassembly of the valve core 2. Furthermore, the inlet end of the valve body 1 is connected to the feed pipe 3, and the outlet end of the valve body 1 is connected to the discharge pipe 4. Both the feed pipe 3 and the discharge pipe 4 are provided with external threads to facilitate the feed pipe 3 and the discharge pipe 4 to be threadedly connected to the external pipeline respectively. Furthermore, the valve body 1 and the feed pipe 3 are sealed by the inlet plug 15 thread. The inlet plug 15 facilitates quick disassembly and assembly of the feed pipe 3 on the valve body 1. The valve body 1 and the discharge pipe 4 are sealed by the outlet plug 16 thread. The outlet plug 16 facilitates quick disassembly and assembly of the discharge pipe 4 on the valve body 1. Furthermore, a sealing ring is provided between the feed pipe 3 and the inlet plug 15, and between the discharge pipe 4 and the outlet plug 16. The sealing ring seals the connection between the feed pipe 3 and the inlet plug 15, and between the discharge pipe 4 and the outlet plug 16, thereby enhancing the sealing performance of the connection between the feed pipe 3 and the discharge pipe 4 and the valve body 1 and preventing leakage of the fluid medium. Furthermore, a temperature and pressure gauge 17 is threadedly embedded on the side of the valve body 1 near the valve core 2. The temperature and pressure inside the valve body 1 are monitored in real time through the temperature and pressure gauge 17 to ensure that the temperature and pressure generated by the fluid medium inside the valve body 1 are within the normal monitoring threshold.

[0022] like Figures 1-11As shown, the inlet and outlet ends of the valve body 1 are provided with turbulence assemblies for turbulence cooperation between the feed pipe 3 and the discharge pipe 4, and the turbulence assemblies include a skeleton 51 embedded in the inlet and outlet ends of the valve body 1. It also includes a flow equalization net 52 embedded in the frame 51, and the flow equalization net 52 is distributed in a triangular equidistant state along the horizontal axis of the frame 51. The frame 51 provides fixed support for the flow equalization net 52, and the flow equalization net 52 plays the role of equalizing flow and stabilizing pressure for the fluid medium flowing into and out of the valve body 1. A rotating hole 53 is provided in the middle of the frame 51, and a hollow rotating shaft 54 ​​rotates inside the rotating hole 53. The rotating hole 53 facilitates the stable rotation of the hollow rotating shaft 54 ​​on the frame 51. The fluid medium flowing into and out of the valve body 1 can also flow through the channel inside the hollow rotating shaft 54 ​​to prevent the fluid medium from flowing too fast and causing turbulence. A turbulence impeller 55 is fitted on the hollow rotating shaft 54. Under the flow impact force generated by the fluid medium in the valve body 1, the turbulence impeller 55 is forced to drive the hollow rotating shaft 54 ​​to rotate in the rotating hole 53 on the frame 51, following the flow direction of the fluid medium. This has a turbulence effect on the fluid medium flowing in and out of the valve body 1, and also relieves its pressure. Furthermore, the turbulence impeller 55 has a hollow cavity 56 that communicates with the hollow rotating shaft 54. Through the hollow cavity 56, the fluid medium flowing into and out of the valve body 1 can flow through the hollow cavity 56 channel reserved in the turbulence impeller 55, further expanding the flow space of the fluid medium and playing an auxiliary pressure relief role. A scraper 57 for cleaning the flow equalization net 52 is fixed on the hollow rotating shaft 54. The scraper 57 is distributed in a triangular equidistant state along the horizontal axis of the hollow rotating shaft 54. The scraper 57, which rotates with the turbulence impeller 55, plays a scraping and cleaning role on the flow equalization net 52 on the frame 51, so as to prevent impurity particles in the fluid medium from adhering to the flow equalization net 52 for a long time, causing blockage of its mesh, and reducing the replacement and cleaning frequency of the flow equalization net 52.

[0023] like Figures 1-11 As shown, the bottom end of the valve body 1 is threadedly connected to the valve seat 6, and the bottom of the valve seat 6 is fixed with the cover 7. The valve seat 6 and the valve body 1 are connected by a thread, which facilitates the quick disassembly and assembly of the valve seat 6 and the cover 7 on the valve body 1 and the overall components inside. All the major components on the valve body 1 are connected by a thread. The pressure reducing and temperature reducing valve adopts a split design, which facilitates the quick disassembly, assembly, maintenance and cleaning of major components. The cover 7 is respectively provided with a rotating component and a cold conduction component that cooperate with the temperature reducing of the valve body 1. The rotating assembly includes a servo motor 81 that is horizontally placed outside the housing 7, and a main bevel gear 82 is sleeved on the output shaft of the servo motor 81. A driven bevel gear 83 meshes with the main bevel gear 82. The servo motor 81 drives the main bevel gear 82 to rotate, and the main bevel gear 82 drives the driven bevel gear 83 to rotate accordingly. An air distribution pipe 84 is fitted inside the bevel gear 83, and the top end of the air distribution pipe 84 is connected to an atomizing nozzle 85 for cooling the valve body 1. When the bevel gear 83 is rotating, it drives the air distribution pipe 84 and the atomizing nozzle 85 to make a swirling motion in the valve cavity of the valve body 1, which is beneficial to the subsequent swirling cooling operation of the cold source. The valve seat 6 is embedded with a flow equalization shroud 86 that rotates with the air distribution pipe 84, and a flow equalization window 87 is opened on the circumference of the flow equalization shroud 86. Through the flow equalization shroud 86 and the flow equalization window 87, the cold source distributed in the valve body 1 is stabilized to prevent turbulence from occurring in the valve body 1 when the cold source is distributed, which is conducive to the cooling operation of the fluid medium carrying heat. The top of the flow equalization hood 86 is provided with a flow equalization port 10 that communicates with the atomizing nozzle 85, and the flow equalization port 10 is located directly above the atomizing nozzle 85. The cold source sprayed from the atomizing nozzle 85 on the air distribution pipe 84 is evenly distributed and reaches the valve cavity inside the valve body 1 after being processed by the flow equalization port 10 on the flow equalization hood 86. This prevents the cold source from causing turbulence due to excessive flow velocity when it is sprayed from the atomizing nozzle 85, and avoids the cold source sprayed from the atomizing nozzle 85 from wandering around. It ensures that the cold source is evenly and fully contacted with the fluid medium flowing through the valve body 1, resulting in comprehensive and effective cooling treatment.

[0024] like Figures 1-11 As shown, the cold conduction assembly includes a cold injection pipe 91 on an external cold source pipeline, and the inner end of the cold injection pipe 91 is connected to a pressurization angle pipe 92. Through the cold injection pipe 91 and the pressurization angle pipe 92, the cold source in the external cold source pipeline is pressurized from the cold injection pipe 91 and injected into the air distribution pipe 84 through the pressurization angle pipe 92. The cooling pipe 91 and the pressure-boosting angle pipe 92 are sealed by a threaded cooling pipe 11. The cooling pipe 91 on the pressure-boosting angle pipe 92 can be quickly disassembled and assembled through the cooling pipe 11. The top end of the pressure-boosting angle tube 92 is connected to a rotating end 93, and a connecting end 94 that is connected to the air distribution tube 84 is rotated inside the rotating end 93. The rotating end 93 and the connecting end 94 are in an interconnected state. Through the rotating end 93 and the connecting end 94, not only can the rotation requirement of the air distribution tube 84 on the connecting end 94 be met, but normal cold source delivery can also be carried out inside the air distribution tube 84. An opening groove 95 is provided on the circumference of the air distribution pipe 84 near the flow equalization hood 86. The opening groove 95 adopts a long strip design. The cold source reaching the air distribution pipe 84 is dispersed and conducted through the opening groove 95. The air distribution pipe 84 is fitted with a conductive sleeve 96 that conducts cold with the opening groove 95. Through the conductive sleeve 96, the cold source dispersed and discharged from the opening groove 95 is conducted to the conductive sleeve 96 area, completing the dispersion and conduction of the cold source. Cooling fins 97 that rotate with the flow equalization shroud 86 are fixed around the conduction sleeve 96, and a gap is reserved between the cooling fins 97 and the flow equalization shroud 86. Through the gap, a cooling space is provided for the cold source conducted and dispersed by the cooling fins 97. The cold source is then conducted to the conduction sleeve 96, reaches the circumferentially distributed cooling fins 97 area, and then disperses the cold source into the flow equalization shroud 86. Through the flow equalization window 87 on it, the cold source is evenly distributed into the valve cavity in the valve body 1, achieving a comprehensive and efficient cooling effect for the fluid medium and preventing uneven cooling of the fluid medium and the occurrence of large temperature differences.

[0025] Both sides of the valve body 1 near the outlet end and the valve seat 6 are connected to bypass heads 12, and the outer end of the bypass head 12 is connected to an interconnecting bend 13. Through the bypass head 12 and the interconnecting bend 13, the fluid medium and cold source in the valve cavity of the valve body 1 can be branched and transported to the area near the outlet end of the valve body 1. Conversely, the fluid medium and cold source branched and transported to the area near the outlet end of the valve body 1 can also be interconnected and reach the valve cavity of the valve body 1, thereby reducing the pressure of the fluid medium in the valve body 1 and the outlet end, and also allowing the discharged fluid medium to be cooled and de-temperatured again. The bypass head 12 and the interconnecting bend 13 are sealed by a bypass plug 14 threaded together. The bypass plug 14 facilitates quick assembly and disassembly of the interconnecting bend 13 on the bypass head 12.

[0026] The working principle of an atomizing nozzle type desuperheating and pressure reducing valve is as follows: First, the valve core 2 and valve seat 6 are threadedly embedded with the valve body 1, and the valve core 2 and valve seat 6 can be quickly disassembled and assembled by turning clockwise and counterclockwise. The feed pipe 3 and valve body 1 are sealed by the inlet plug 15, and the feed pipe 3 can be quickly disassembled and assembled by turning the inlet plug 15 clockwise and counterclockwise. The discharge pipe 4 and valve body 1 are sealed by the outlet plug 16, and the discharge pipe 4 can be quickly disassembled and assembled by turning the outlet plug 16 clockwise and counterclockwise. The whole adopts a threaded disassembly design, which facilitates quick disassembly and maintenance. During the process of the fluid medium flowing from the feed pipe 3 through the valve body 1 and out through the discharge pipe 4, the flow force generated by the fluid medium forces the turbulence impeller 55 on the hollow rotating shaft 54 ​​at the feed pipe 3 and the discharge pipe 4 to rotate in the rotating hole 53 in the frame 51, and performs turbulence and pressure relief treatment on the inflowing and outflowing fluid medium, and the flow equalization treatment is performed by the flow equalization net 52 on the frame 51. At the same time, the fluid medium can also be assisted to flow in and out through the hollow cavity 56 reserved by the turbulence impeller 55 and the hollow rotating shaft 54. During this period, the rotating turbulence impeller 55 drives the scraper 57 to rotate through the hollow rotating shaft 54, and scrapes and cleans the impurity particles attached to the flow equalization net 52. At the same time, the cold source in the external cold source pipeline is injected into the pressurized angle tube 92 through the cold injection pipe 91 in one direction, and then injected into the air distribution pipe 84 through the rotating end 93 and the connecting end 94 in sequence. The servo motor 81 is turned on and drives the bevel gear 83 to rotate through the main bevel gear 82. The bevel gear 83 drives the air distribution pipe 84 and the atomizing nozzle 85 to rotate synchronously. The cold source injected into the air distribution pipe 84 is then sprayed into the valve body 1 from the atomizing nozzle 85 in a swirling manner. During this period, the cold source injected into the pressurized air distribution pipe 84 also reaches the conduction sleeve 96 through the opening groove 95, and conducts the cold source to the cooling fin 97 area that rotates synchronously with the air distribution pipe 84. The cold source conducted to the cooling fin 97 then rotates and disperses, and disperses outward and upward through the flow equalization window 87 and flow equalization port 10 on the flow equalization shroud 86. The temperature and pressure inside the valve body 1 are always monitored in real time by the temperature and pressure gauge 17. Furthermore, the fluid medium and cold source in the valve body 1 near the valve seat 6, and the fluid medium and cold source in the valve body 1 near the discharge pipe 4, are mutually pressure-relieving and temperature-reducing through the interconnecting bends 13 on the two sets of bypass heads 12. The interconnecting bends 13 on the two sets of bypass heads 12 can be quickly disassembled and repaired by turning the bypass plug head 14 clockwise and counterclockwise.

[0027] It should be noted that the specific models and specifications of valve core 2 and servo motor 81 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.
