Description

Technical Field

[0001] The invention relates to the field of descaling valves, and in particular to a descaling valve for descaling. Background Art

[0002] Scale is mainly formed when salts such as calcium and magnesium contained in boiler feed water precipitate and adhere to the metal surface after heating. The thermal conductivity of scale is very small, about 2% to 5% of ordinary steel. Scale formed on the heating surface of the boiler will greatly deteriorate the heat transfer effect and affect the efficiency of the boiler. After scale is formed, it should be removed in time by mechanical or chemical methods.

[0003] On the market, descaling valves are usually used to eliminate scale in boiler feed water, because scaling is caused by the accumulation of calcium and magnesium ions (salts that determine the hardness of water) in the water on the inner wall of the pipe, the surface of the heat exchanger and the inside of the control and regulating elements. The amount of scale accumulation depends on the temperature, hardness and water consumption of the water. Unlike other salts, the solubility of calcium and magnesium salts decreases when the water temperature rises. For this reason, the risk of scaling is particularly high in systems that produce hot water. The parameters that need to be controlled to prevent scaling include the total hardness of the water, the total concentration of calcium and magnesium ions, and the chemical structure of calcium bicarbonate, calcium carbonate, water and carbon dioxide. When the water temperature rises, the soluble calcium bicarbonate decomposes to release carbon dioxide and generates insoluble calcium carbonate, forming water scale. The traditional descaling valves on the market use chemical reactions to form a compound similar to scale that adheres to the inner wall of the pipe, making it impossible to isolate the oxygen in the water from the metal, resulting in corrosion and scaling. At the same time, the existing scale in the pipe cannot be discharged smoothly.

[0004] In addition, when using the chemical reaction in the descaling valve to eliminate calcium carbonate in the water, it is important to control the flow rate of the water source entering the descaling valve, because the chemical reaction of the water source plays a role in preventing scale formation and removing the formed scale. If the water source flow rate is too fast, the reaction time will be shortened, and the reaction requires a certain amount of time. Too fast a flow rate makes the water and the reaction conditions not fully react, and the calcium carbonate in the water cannot be effectively removed, which reduces the descaling effect. At the same time, when high-speed water flows through the descaling valve, a large pressure fluctuation will be generated. This pressure fluctuation will affect the stability of the entire water supply system. When the flow rate in the pipeline is too fast, the water flow has a large kinetic energy. If the valve is suddenly closed, the pump suddenly stops running, or the direction of the water flow changes sharply, due to the inertia of the water flow, the high-speed flowing water will stop or change direction in an instant, thereby generating a huge impact force. This impact force will quickly propagate and reflect in the pipeline in the form of pressure waves, thereby forming a water hammer effect. If the water flow rate cannot be limited, it will cause serious damage to pipeline accessories such as pumps, valves, and flow meters, for example, the impeller of the pump will be deformed, the shaft will be broken, and the valve seal will fail.

[0005] Secondly, traditional descaling valves on the market usually use filters to filter impurities produced after the calcium carbonate reaction. A large amount of impurities will be generated during the long-term working process, which will eventually cause the filter to be blocked, thereby affecting the normal operation of the descaling valve, and causing the traditional filter to be unable to meet the descaling requirements of the descaling valve.

[0006] Therefore, it is necessary to provide a descaling valve for descaling, aiming to solve the above problems. Summary of the invention

[0007] In view of the shortcomings of the prior art, an object of the present invention is to provide a descaling valve for descaling.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a descaling valve for descaling, comprising a descaling valve body, a water outlet and a transparent tank body, wherein the water outlet is arranged at the top of the descaling valve body, the transparent tank body is arranged at the bottom of the descaling valve body, a liquid speed regulating component for controlling the flow speed of a water source is arranged on the outside of the descaling valve body, a power component for providing power to the liquid speed regulating component is arranged on the outside of the descaling valve body, and an anti-blocking component for preventing blockage of the top of the transparent tank body is arranged inside the descaling valve body.

[0009] Preferably, the power assembly includes a distance increasing tube, which is fixedly connected to the outer side of the descaling valve body, and the inside of the distance increasing tube is rotatably connected to a blade rod, the bottom of the blade rod is fixedly connected to a balance plate, the top of the blade rod is slidably connected to a power sliding plate, the bottom of the power sliding plate is symmetrically rotatably connected to a connecting plate, and the ends of the two connecting plates away from the power sliding plate are rotatably connected to a spherical tilting rod.

[0010] Preferably, the liquid speed regulating assembly includes a positioning rod, the positioning rod is fixedly connected to the top of the distance increasing tube, the top of the positioning rod is rotatably connected to a Y-shaped rotating rod, one end of the Y-shaped rotating rod is rotatably connected to a rotating block, the end of the Y-shaped rotating rod away from the rotating block is rotatably connected to a connecting rod, the end of the connecting rod away from the Y-shaped rotating rod is rotatably connected to a rotating plate, and the interior of the descaling valve body is rotatably connected to a liquid blocking block.

[0011] Preferably, the anti-clogging component includes a sealing plate, which is clamped to the inside of the descaling valve body through a sealing ring, and the inside of the sealing plate is rotatably connected to a filter disc, and a triangular plate group is arranged above the filter disc.

[0012] Preferably, the tops of the two spherical tilting rods are rotatably connected to the top of the blade rod.

[0013] Preferably, the rotating block is slidably connected to the inside of the power sliding plate, and the rotating plate and the liquid blocking block are arranged at a parallel angle.

[0014] Preferably, the aperture of the filter disc gradually increases from the center to the edge area, and the triangular plate group is fixedly connected to the top of the sealing plate.

[0015] Preferably, one-way valves are provided inside the descaling valve body and at the bottom of the water outlet, and the transparent tank body is made of PA.

[0016] The descaling valve provided by the present invention for descaling has the following beneficial effects compared with the prior art:

[0017] 1. Through the setting of the power assembly and the liquid speed adjustment, before the water source enters the descaling valve body through the distance increase pipe, if the water source flow rate is too fast, the fan blade rod will accelerate the rotation with the liquid flow rate. When the water source exceeds the safety standard, the fan blade rod and the spherical tilting rod pull the power slide plate down through the connecting plate due to the increase in eccentricity, and then the power slide plate moves the rotating plate and the liquid blocking block through the rotating block and the Y-shaped rotating rod, so that the liquid blocking block limits the water source flow rate entering the descaling valve body, and finally achieves the purpose of reducing the liquid flow rate. Compared with the traditional descaling valve, which cannot effectively control the water flow rate, this structure can automatically adjust the angle of the liquid blocking block according to the water flow rate to realize intelligent control of the water flow rate. When the water source flow rate is too fast, the system can respond in time to reduce the flow rate to ensure the descaling effect and the safe operation of the equipment. The unique spherical design of the spherical tilting rod increases the flexibility of the connection with the connecting plate, so that under the action of centrifugal force, the connecting plate can be pulled more stably to ensure the accuracy and reliability of the action;

[0018] Secondly, the appropriate water flow rate helps the silicon phosphorus crystals to fully contact and react with the calcium carbonate in the water, thereby improving the descaling efficiency. By automatically controlling the water flow rate, the structure can always maintain a flow rate range that is conducive to descaling, allowing the silicon phosphorus crystals to better play a descaling role, reducing the formation and accumulation of scale, and avoiding the damage of valves and pipes caused by excessive pressure due to the water hammer effect when the traditional descaling valve faces a water flow with a too fast flow rate. The structure can automatically reduce the flow rate when the flow rate is too fast, reduce the damage to the equipment caused by the water hammer effect, extend the service life of the equipment, and reduce maintenance costs.

[0019] 2. Through the setting of the anti-clogging component, when the water flows into the descaling valve, due to the setting of the triangular plate group, the water source generates pressures of different angles on the filter disc through the triangular plate group, thereby causing the filter disc to vibrate. The shape of the triangular plate is strong and durable, and can withstand the long-term impact of the water flow without deformation. At the same time, the installation angle of the triangular plate can ensure that the water flow can exert pressure on the filter disc at the best angle, thereby generating effective vibration;

[0020] At the same time, because the filter disc is designed into areas with different apertures, when water flows through areas with different apertures, different pressures will be generated due to the difference in water flow resistance. This pressure difference will cause the filter to be subjected to different forces in different areas. Since the central area of ​​the filter is set with a smaller aperture and the edge area is set with a larger aperture, when water flows through, the pressure in the central area will be greater than that in the edge area, causing the filter to deform and vibrate toward the edge, thereby avoiding the accumulation of impurities produced after the calcium carbonate reaction on the filter disc, preventing the filter disc from being blocked, and avoiding affecting the normal operation of the descaling valve.

Therefore, they should not be understood as limitations on the present invention.

[0035] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0036] Implementation example Figures 1 to 8 As shown, a descaling valve for descaling provided by an embodiment of the present invention includes a descaling valve body 11, a water outlet 12 and a transparent tank body 13, the water outlet 12 is arranged at the top of the descaling valve body 11, the transparent tank body 13 is arranged at the bottom of the descaling valve body 11, a liquid speed regulating component for controlling the flow speed of the water source is arranged on the outside of the descaling valve body 11, a power component for providing power to the liquid speed regulating component is arranged on the outside of the descaling valve body 11, and an anti-blocking component for preventing the top of the transparent tank body 13 from being blocked is arranged inside the descaling valve body 11.

[0037] Silicon phosphorus crystals are placed inside the transparent tank 13 to allow the silicon phosphorus crystals to react with water sources to reduce the formation of scale.

[0038] The power assembly includes a distance increasing tube 21, which is fixedly connected to the outer side of the descaling valve body 11, and the inside of the distance increasing tube 21 is rotatably connected to a blade rod 22, the bottom of the blade rod 22 is fixedly connected to a balance plate 23, the top of the blade rod 22 is slidably connected to a power sliding plate 24, the bottom of the power sliding plate 24 is symmetrically rotatably connected to a connecting plate 25, and the ends of the two connecting plates 25 away from the power sliding plate 24 are rotatably connected to a spherical tilting rod 26.

[0039] The liquid speed regulating assembly includes a positioning rod 31, which is fixedly connected to the top of the distance increasing tube 21, and the top of the positioning rod 31 is rotatably connected to a Y-shaped rotating rod 32, one end of the Y-shaped rotating rod 32 is rotatably connected to a rotating block 33, the end of the Y-shaped rotating rod 32 away from the rotating block 33 is rotatably connected to a connecting rod 34, the end of the connecting rod 34 away from the Y-shaped rotating rod 32 is rotatably connected to a rotating plate 35, and the interior of the descaling valve body 11 is rotatably connected to a liquid blocking block 36.

[0040] The anti-clogging component includes a sealing plate 41 , which is clamped to the inside of the descaling valve body 11 through a sealing ring. A filter disc 42 is rotatably connected to the inside of the sealing plate 41 , and a triangular plate group 43 is arranged above the filter disc 42 .

[0041] The tops of the two spherical tilting rods 26 are both rotatably connected to the top of the blade rod 22. During the rotation of the two spherical tilting rods 26, the eccentricity can be used to pull the connecting plate 25 down.

[0042] The rotating block 33 is slidably connected to the inside of the power sliding plate 24, so that the power sliding plate 24 can drive the Y-shaped rotating rod 32 to rotate through the rotating block 33. The rotating plate 35 and the liquid blocking block 36 are arranged at a parallel angle, so that the liquid blocking block 36 rotates synchronously during the rotation of the rotating plate 35.

[0043] The aperture of the filter disc 42 gradually increases from the center to the edge area, so that the filter disc 42 is subjected to different forces in different areas. The triangular plate group 43 is fixedly connected to the top of the sealing plate 41, so that the triangular plate group 43 impacts the filter disc 42 at different angles.

[0044] One-way valves are provided inside the descaling valve body 11 and at the bottom of the water outlet 12 to prevent the treated water from flowing back into the tap water system and to prevent salt from seeping into the pipe system when not in use for a long time. The transparent tank body 13 is made of PA, which has strong chemical stability, good toughness and transparency, allowing people to clearly see the amount of silicon phosphorus crystals inside, making it convenient for users to add medicines in time.

[0045] Working principle: In the initial state, the power slide plate 24 is located at the top of the blade rod 22, and the positioning rod 31 and the Y-shaped rotating rod 32 are in a vertical state.

[0046] During operation, the descaling valve body 11 must be installed vertically upward and cannot be inverted. Following the water flow direction marked on the valve body, the staff first connects the water source to the distance increasing pipe 21, so that the water source flows into the descaling valve body 11 through the distance increasing pipe 21. During this process, the flow rate of the water source will drive the blade rod 22 to rotate synchronously. When the flow rate is too fast, the tops of the two spherical tilting rods 26 are rotated and connected to the tops of the blade rods 22. At this time, the blade rod 22 will drive the two spherical tilting rods 26 at the top to rotate under the action of eccentricity, and the two spherical tilting rods 26 will pull the power slide plate 24 down through the connecting plate 25;

[0047] When the power slide plate 24 slides along the top of the blade rod 22, the power slide plate 24 drives the rotating block 33 to descend synchronously, so that the rotating block 33 drives the Y-shaped rotating rod 32 to rotate along the positioning rod 31. Under the action of the lever, the end of the Y-shaped rotating rod 32 away from the rotating block 33 pulls the connecting rod 34 to rise, and the end of the connecting rod 34 away from the Y-shaped rotating rod 32 drives the rotating plate 35 and the liquid blocking block 36 to rotate.

[0048] Because the liquid blocking block 36 rotates inside the descaling valve body 11, when the liquid blocking block 36 rotates, the liquid blocking block 36 will form a certain resistance to the water flow, thereby reducing the flow rate of the water source, and finally achieving the purpose of reducing the liquid flow rate. Compared with the traditional descaling valve, which cannot effectively control the water flow rate, the structure can automatically adjust the angle of the liquid blocking block 36 according to the water flow rate, and realize intelligent control of the water flow rate. When the water source flow rate is too fast, the system can respond in time to reduce the flow rate, ensure the descaling effect and the safe operation of the equipment, and prevent the occurrence of water hammer phenomenon and avoid the impact of the water hammer effect;

[0049] After the water source flows into the descaling valve body 11 through the distance increasing pipe 21, the water source will impact the filter plate 42 along the triangular plate group 43, and the triangular plate group 43 is set at two different horizontal heights, so that the water source impacts the filter plate 42 at different angles, causing the filter plate 42 to vibrate;

[0050] At the same time, the filter disc 42 is designed to have different aperture areas. When water flows through the different aperture areas, different pressures will be generated due to the difference in water flow resistance. This pressure difference will cause the filter disc 42 to be subjected to different forces in different areas. Since the central area of ​​the filter disc 42 is set with a smaller aperture and the edge area is set with a larger aperture, when water flows through, the pressure in the central area will be greater than that in the edge area, causing the filter to deform and vibrate toward the edge.

[0051] Finally, because silicon phosphorus crystals are placed inside the transparent tank body 13, the silicon phosphorus crystals react with the water source to reduce the formation of scale. After the water source reacts with the silicon phosphorus crystals inside the transparent tank body 13, it will flow along the filter plate 42 to the water outlet 12, thereby preventing the formation of scale, thereby avoiding the accumulation of impurities generated after the calcium carbonate reaction on the filter plate 42, preventing the filter plate 42 from being blocked, and ensuring the normal operation of the descaling valve body 11. At the same time, the transparent tank body 13 is made of PA, which has strong chemical stability, good toughness, and transparency, so that people can clearly see the amount of silicon phosphorus crystals inside, which is convenient for users to add medicines in time. At the same time, the consumption status of silicon phosphorus crystals can be easily observed through the transparent tank body. Adding a few black indicator particles in the medicine can reflect the use of the medicine. If the black particles are not visible, it proves that more than 60% of the medicine remains, because the black particles will be suspended on the top of the medicine box. When the black particles sink to the bottom of the medicine box, the medicine needs to be added again.

[0052] One-way valves are provided inside the descaling valve body 11 and at the bottom of the water outlet 12 to prevent the treated water from flowing back into the tap water system and to prevent salt from penetrating into the pipe system when the descaling valve body 11 is not used for a long time.
