Description

Technical Field

[0001] This invention relates to the field of control valve technology, and in particular to an anti-crystallization overflow control valve and its usage method. Background Technology

[0002] Valves are indispensable components in fluid transport pipelines and are widely used in the fluid transport field. In the transport of some impure media, valve failure often leads to media leakage, which may affect production or, in critical scenarios such as chemical engineering, may even cause dangerous accidents.

[0003] For fluid transport in high-concentration saline wastewater treatment systems, it is crucial to prevent media crystallization. Crystals accumulate in the corners of pipelines, gradually clogging them. For valves, crystals on the sealing surface also affect the shut-off function of the control valve, causing leakage. Traditional valve bodies have inlet and outlet on the same straight line, and the flow channel inside the valve body inevitably has bends and flow passages. The sealing surface of the valve core that needs to be sealed is often a non-cylindrical or non-conical irregular curved surface. This not only makes casting relatively complex, but also makes it difficult to clean the crystals adhering to the irregular curved surface during valve maintenance. It often requires increasing the frequency of maintenance to ensure reliable use.

[0004] To address the above technical problems, this invention discloses an anti-crystallization overflow regulating valve and its usage method. This invention has the advantages of removing crystals adhering to the valve body, ensuring normal liquid flow through the regulating valve. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an anti-crystallization overflow regulating valve and its usage method to solve the problems mentioned in the background art.

[0006] This invention is achieved through the following technical solution: This invention discloses an anti-crystallization overflow regulating valve, including a valve body, the valve body including an input pipe and an output pipe, a ball valve built into the connection between the two, and an operating valve handle configured on the surface of the ball valve to realize rotation control; The input tube integrates a cleaning component to remove crystals from the flowing medium; The cleaning assembly includes a flow restrictor, a guide vane, a driven ring, and a driven shaft, which are fitted inside the input pipe, with an inlet at one end and an outlet at the other end. The guide vane is rotatably disposed inside the flow-limiting cylinder, and the driven ring is fixed to the end of the central shaft of the guide vane; The driven shafts are provided in four sets and are evenly distributed around the end face of the driven ring. Each set of driven shafts has multiple sets of arc-shaped blades on its outer wall along the axial direction to scrape off the crystals on the inner wall of the input pipe.

[0007] Furthermore, semiconductor heating elements are mounted on both sides of the ball valve, and a battery capable of providing power to the semiconductor heating elements is installed on the outside of the output pipe.

[0008] Furthermore, the cutting end of the arc-shaped blade has a cutting edge to form a composite cutting structure of a first cutting edge and a second cutting edge, which is used to cut the crystals in stages to reduce resistance.

[0009] Furthermore, the arc-shaped blades on the adjacent sets of driven shafts are staggered, and the ends of the four sets of driven shafts are connected by cross-shaped reinforcing ribs to enhance structural stability.

[0010] Furthermore, the ball valve has fixed blades inside, with the edges of the blades closely attached to the inner wall of the ball valve. Fluid impact drives the blades to rotate, scraping away crystals from the inner wall of the valve cavity.

[0011] Furthermore, a wire groove is formed inside the valve handle, and the wires between the semiconductor heating element and the battery are arranged in the wire groove, with the wire length meeting the requirements for the full stroke rotation of the valve handle.

[0012] Furthermore, the cleaning assembly also includes a filter screen that fits onto the end face of the end ring at the end of the flow restrictor, and the end face of the end ring has a reserved annular groove to fit the filter screen.

[0013] Furthermore, both the input and output pipes are constructed by connecting a flange pipe and a ball valve pipe. A threaded sleeve is rotatably installed on the outer wall of the ball valve pipe. The inner wall of the threaded sleeve is threadedly engaged with the outer wall of the flange pipe. A hexagonal handle is fixed to the outer wall of the threaded sleeve. Rotating the hexagonal handle can adjust the extension and retraction lengths of the input and output pipes.

[0014] Furthermore, the ball valve is equipped with a temperature detection sensor to monitor the wastewater temperature inside the ball valve in real time, and the controller dynamically adjusts the power of the semiconductor heating element based on the detection data.

[0015] A method for using an anti-crystallization overcurrent regulating valve includes the following steps: S1. Wastewater flows into the ball valve and impacts the blades, which rotate to scrape away the crystals on the inner wall of the valve cavity. S2, a semiconductor heating element heats the ball valve and the wastewater flowing through it, and the controller maintains the temperature above the crystallization point; S3. When high-concentration salt wastewater enters the inlet pipe, it impacts the guide vanes, causing them to rotate. This causes the arc-shaped blades to scrape away the crystals from the inner wall of the inlet pipe, which are then discharged along with the flow of the wastewater. S4. Rotate the hexagonal handle to adjust the extension and retraction length of the input and output tubes, and then tighten the threaded sleeve after adapting to the installation space.

[0016] The present invention has the following advantages: (1) The present invention uses the impact force of wastewater to drive the guide vane to rotate by setting up a cleaning component. The driven ring and driven shaft connected to it will rotate synchronously at the first time, thereby driving the arc blade to rotate to efficiently scrape and clean the crystals on the inner wall of the input pipe, effectively preventing the blockage problem caused by the accumulation of crystals; at the same time, the first cutting edge and the second cutting edge of the arc blade form a compound cutting angle, which cuts the crystals attached to the inner wall of the input pipe in two stages, thereby reducing the resistance of the crystals to the arc blade 280, and can efficiently remove the salt crystals attached to the pipe wall; (2) The present invention can also drive the blades to rotate by setting wastewater. The flow impact force of high-concentration salt wastewater drives the blades to rotate, thereby automatically scraping off the crystals attached to the inner wall of the ball valve, effectively preventing flow channel blockage and sealing surface failure, while reducing external energy dependence. At the same time, in conjunction with the semiconductor heating element, the temperature of the ball valve body and the temperature of the wastewater flowing through the valve cavity are always higher than its crystallization critical point, fundamentally inhibiting crystal formation.

[0019] The embodiments of the present invention are described in detail below. These embodiments are implemented based on the technical solution of the present invention, and provide detailed implementation methods and specific operation processes. However, the scope of protection of the present invention is not limited to the following embodiments. In the description of the present invention, words such as "front", "rear", "left", and "right" that indicate orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Example

[0020] This embodiment discloses an anti-crystallization overflow regulating valve, such as Figures 1 to 7 The valve body 100 includes an inlet pipe 110 and an outlet pipe 120, with a ball valve 130 built into the connection. The ball valve 130 is equipped with an operating handle 140 to achieve rotation control. The inlet pipe 110 integrates a special cleaning component 200 to remove crystals in the flowing medium, ensuring unobstructed flow and valve sealing performance.

[0021] like Figures 1-6 As shown, the ball valve 130 has a blade 131 that can be rotated by liquid impact. Semiconductor heating elements 160 are mounted on both sides of the ball valve 130. A battery 180 that can provide power to the semiconductor heating elements 160 is installed on the outside of the output pipe 120. The cleaning assembly 200 includes a flow-limiting cylinder 230 sleeved in the input pipe 110. A guide vane 240 is rotatably provided in the flow-limiting cylinder 230. A driven ring 250 that can be rotated by the central axis of the guide vane 240 is provided at the end of the flow-limiting cylinder 230. Four sets of circumferentially arranged driven shafts 260 are fixed on the end face of the driven ring 250. The outer wall of each set of driven shafts 260 is provided with multiple sets of arc-shaped blades 280 that can remove crystals from the inner wall of the input pipe 110 along its axial direction. An end ring 210 is fixed at the end of the flow-limiting cylinder 230 away from the driven ring 250. The end ring 210 is fitted into the end face of the input pipe 110.

[0022] It is worth noting that one end of the flow-limiting cylinder 230 is provided with an inlet 231, and the other end of the flow-limiting cylinder 230 is provided with an outlet. The outer wall of the central shaft of the guide vane 240 is provided with a positioning frame fixed inside the flow-limiting cylinder 230. A wire groove 161 is provided inside the valve handle 140. The wires connecting the semiconductor heating element 150 and the battery 180 are arranged in the wire groove 161, and the length of the wires is sufficient to allow the valve handle 140 to rotate to complete the opening and closing of the ball valve 130. like Figure 4 As shown, the cleaning component 200 also includes a filter screen 220 that fits onto the end face of the end ring 210, and a ring groove 150 is reserved at the position corresponding to the end face of the end ring 210 and the filter screen 220 and the end ring 210.

[0023] like Figure 5 As shown, the curved surface of the arc-shaped cutter 280 is fixed with a cutter ring 270 that is sleeved on the outer wall of the driven shaft 260. The outer wall of the driven shaft 260 is provided with a keyway that matches the internal dimensions of the cutter ring 270. The cutter ring 270 is fixed in the keyway with screws.

[0024] The curved blade 280 has a cutting edge 281 at the external corner of its cutting end, which divides the cutting end of the curved blade 280 into a first cutting edge 282 and a second cutting edge 283.

[0025] The arc-shaped blades 280 fixed to the outer wall of the two adjacent driven shafts 260 are in a staggered position, and the ends of the four driven shafts 260 are fixed with cross-shaped reinforcing ribs.

[0026] Wastewater rich in high concentrations of salts enters the inlet pipe 110 and flows along its axial direction. It passes through the cleaning component 200 and enters the ball valve, then exits through the outlet pipe 120. When the wastewater flows through the flow-limiting cylinder 230, its specific flow channel design causes the fluid to concentrate and impact the guide vanes 240. The guide vanes 240 rotate under the action of fluid kinetic energy, driving the driven ring 250 to rotate synchronously via the central shaft. The four sets of driven shafts 260 fixed to the driven ring 250 then move circumferentially, driving the arc-shaped blades 280 distributed along the axis to perform circumferential scraping on the inner wall of the inlet pipe 110. The first cutting edge 282 and the second cutting edge 283 of the arc-shaped blades 280 (see...) Figure 5 The composite cutting angle is formed to cut the crystals attached to the inner wall of the input pipe 110 in two stages, thereby reducing the resistance of the crystals to the arc-shaped blade 280 and efficiently removing the salt crystals attached to the pipe wall. The scraped-off crystals are discharged with the wastewater. In this process, the cross reinforcing ribs effectively enhance the structural stability of the end of the driven shaft 260 and prevent deformation during high-speed rotation. like Figure 7 As shown, the outer wall of the output pipe 120 is provided with a positioning platform 170 outside the valve handle 140, and the battery 180 is installed on the top of the positioning platform 170. The top of the positioning platform 170 is also provided with a controller 190 that can control the upper limit of the temperature of the semiconductor heating element 160.

[0027] It is worth mentioning that the ball valve 130 is equipped with a temperature detection sensor, and the wastewater rich in high concentrations of salts then enters the cavity of the ball valve 130, where the fluid directly impacts the vane 131 fixed to the valve core (see...). Figure 5The blade 131 rotates under impact force, and its edge moves closely against the inner wall of the ball valve 130, forming a continuous scraping effect, effectively removing the crystal deposits on the inner surface and sealing area of ​​the ball valve 130. At the same time, the semiconductor heating plates 160 installed on both sides of the ball valve 130 are connected to the battery 180 through the wires laid in the wire groove 161. The temperature detection sensor detects the temperature of the wastewater, and the controller 190 monitors and adjusts the heating power of the semiconductor heating plates 160 in real time, so that the temperature of the ball valve 130 body and the temperature of the wastewater flowing through the valve cavity are always higher than its crystallization critical point, fundamentally inhibiting the formation of crystals. The positioning platform 170 provides a stable mounting base for the battery 180 and the controller 190, ensuring the reliability of electrical components under vibration conditions. Example

[0028] The differences between this embodiment and Embodiment 1 are as follows: Figure 3 As shown, both the input pipe 110 and the output pipe 120 are constructed by connecting a flange pipe 101 and a ball valve pipe 102. The outer wall of the ball valve pipe 102 is rotatably provided with a threaded sleeve 104 that fits onto the outer wall of the flange pipe 101. The inner wall of the threaded sleeve 104 is threaded to the outer wall of the flange pipe 101. A hexagonal shank 103 is fixed to the outer wall of the threaded sleeve 104. The end of the ball valve pipe 102 away from the flange pipe 101 is provided with an integrally cast connecting flange 105. The two sets of connecting flanges 105 are fixed with bolts and wrapped around the outer wall of the ball valve 130. The mating surfaces of the two sets of connecting flanges 105 are provided with sealing rings.

[0029] When adjusting the length of the input pipe 110 and the output pipe 120, a special tool is used to apply external force to the outside of the hexagonal handle 103, which then drives the threaded sleeve 104 to rotate. After rotating the threaded sleeve 104, the connection position between the input pipe and the output pipe is changed through its thread engagement, thereby precisely adjusting the length to meet the needs of different installation environments.

[0030] A method for using an anti-crystallization overcurrent regulating valve includes the following steps: S1. When wastewater rich in high concentration of salts enters the inlet pipe 110, it can flow along its axis and enter the outlet pipe 120 through the ball valve 130, and then be discharged into the pipe connected to it. When it flows through the ball valve 130, the wastewater hits the blade 131 and makes it rotate. The edge of the blade 131 scrapes the inner wall of the ball valve 130. This scraping action continues and effectively prevents crystals from accumulating on the curved surface of the valve core. S2. The semiconductor heating element 160 is powered by the battery 180. It heats the ball valve 130 body and the wastewater with high concentration of salt flowing through the ball valve 130, so that the temperature of the valve body 100 is kept above the crystallization point of the wastewater with high concentration of salt. The heating process is set with an upper limit temperature by the controller 190, usually in the range of 50-70°C, to ensure safety and efficiency. S3. When high-concentration salt wastewater enters the inlet pipe 110, it will first flow through the flow restrictor 230. The wastewater impacts the guide vane 240, causing it to rotate. Subsequently, the driven ring 250 and the driven shaft 260 rotate synchronously, causing the arc blade 280 to scrape off the crystals on the inner wall of the inlet pipe 110. The crystals are discharged along with the flow of wastewater. The staggered arc blades 280 cover the entire inner wall surface without leaving any dead corners. S4. When the inlet pipe 110 and outlet pipe 120 are separate, they can extend and retract along the axial direction with the help of flange pipe 101 and ball valve pipe 102. With the locking effect of threaded sleeve 104, they can meet the installation requirements of various sites. For example, in a narrow space, the extension length can be adjusted by rotating hexagonal handle 103 and then locked, simplifying the installation process.

[0031] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
