Abstract
Description
Technical Field
[0001] This utility model relates to the field of valve technology, and in particular to a hemispherical valve with a filtration and cleaning function. Background Technology
[0002] In many fields of industrial production, such as petrochemicals, wastewater treatment, and food processing, fluid transportation and control are key links. As the core component of fluid control systems, the performance of valves directly affects the stability, efficiency, and product quality of the production process. As a new type of ball valve, the hemispherical valve has shown significant advantages in many working conditions due to its unique structure, and its application has become increasingly widespread in recent years.
[0003] The existing equipment produces a solid-liquid mixture after the material reaction. This mixture needs to be filtered by an independent filtration device to separate the liquid from the particulate solids. The mixture is then discharged through relevant pipelines and valves to proceed to the next step. After this step, the reactor needs to be cleaned. Conventional equipment requires a large number of pipelines and valves, which takes up a lot of space and has excessive space requirements. Furthermore, the cost of stacking various devices is too high and it is not convenient for practical use and operation.
[0004] Therefore, there is an urgent need to provide a ball valve with a filtration and cleaning function to solve the above problems. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a hemispherical valve with a filtration and cleaning function.
[0006] To solve the above-mentioned technical problems, the present invention provides a hemispherical valve with a filtration and cleaning function, comprising a valve body, wherein ports A and B are respectively opened on the outer wall of the valve body at the top and bottom positions, ports C and D are respectively opened on the outer wall of the valve body, a rotating filter assembly is provided inside the valve body, a sealing ring and multiple rotating O-rings are respectively installed between the rotating filter assembly and the valve body, a bearing is installed inside the valve body, a drain port end cap corresponding to port C is installed on the outer wall of the valve body, a lower end connection end cap corresponding to port B is installed on the outer wall of the valve body, a three-position actuator is installed on one side of the valve body, and a drive shaft end cap is installed on the outer wall of the valve body near the three-position actuator.
[0007] The present invention is further configured such that the valve body is connected to the main equipment via a quick-release chuck.
[0008] With the above technical solution, the quick-install chuck connection does not require complicated tools and operating procedures. The operator only needs to align the quick-install chuck of the valve body with the corresponding interface on the main equipment, and then complete the connection through simple operation, which greatly shortens the installation time and improves work efficiency.
[0009] The present invention is further configured such that: the inner wall of the valve body is provided with an anti-scaling coating, and the outer side of the valve body is provided with a heat insulation layer.
[0010] Through the above technical solutions, the anti-scaling coating can reduce the surface roughness of the valve body, making it difficult for materials to adhere, reducing material residue, avoiding blockage caused by material residue, ensuring the normal flow capacity of the valve, and the heat insulation layer on the outside of the valve body can effectively reduce heat loss or the introduction of external heat, keep the material within a suitable temperature range, reduce energy waste, and lower production costs.
[0011] The present invention is further configured such that: the rotating filter assembly includes a valve core rotatably connected to the inside of the valve body, the top of the valve core is provided with a particle filtration zone, and the inside of the valve core is provided with a liquid channel and two mounting seats respectively.
[0012] Through the above technical solution, after the material reaction is completed, the three-position actuator drives the valve core to rotate to a specific position, aligning the particle filtration zone at the top of the valve core with port A of the valve body. This opens the valve connected to the drain port C. The solid-liquid mixture flows towards the valve core under pressure or gravity. The particle filtration zone traps particulate solids, while the liquid enters the liquid channel inside the valve core through the pores of the particle filtration zone. The liquid then flows from port C into the liquid recovery device, thus achieving solid-liquid separation. When it is necessary to discharge the trapped particulate solids, the three-position actuator controls the valve core to rotate 90 degrees, positioning it at the drain port D. The upper port A and lower port B of the valve body are connected. The particulate solids, relying on their own gravity, fall from port A through the channel between the valve core and the valve body into the lower connected discharge and fixing particle device B. In the port connection device, after the discharge of particulate solids is completed, the three-position actuator controls the valve core to rotate another 90 degrees, for a total rotation of 180 degrees, so that the valve core is at the lower port B, and the upper port A and the sewage port D are connected. Cleaning liquid is injected into the reaction device, such as the reactor, and the cleaning liquid cleans the reactor. The sewage generated during cleaning enters the channel between the valve core and the valve body through port A, and then is discharged into the sewage pipe through port D, thus realizing the cleaning function of the reactor. The two mounting seats inside the valve core are used to install bearings that cooperate with the bearings installed inside the valve body. This structural design ensures the stability and smoothness of the valve core rotation inside the valve body, reduces friction and wear during rotation, and ensures that the valve core can rotate accurately to different positions, reliably realizing the functions of solid-liquid separation, material discharge and cleaning.
[0013] The present invention is further configured such that: the sealing ring is disposed at the circumferential position where the rotating filter assembly contacts the valve body, and the plurality of rotating O-rings are distributed at intervals along the rotational direction of the rotating filter assembly.
[0014] Through the above technical solution, the sealing ring set at the circumferential position where the rotating filter assembly contacts the valve body can form a tight sealing barrier between the two. During solid-liquid separation and cleaning, it can effectively prevent liquid from seeping out from the contact gap between the rotating filter assembly and the valve body. Multiple rotating O-rings are distributed at intervals along the rotation direction of the rotating filter assembly, which can provide a continuous and effective seal when the rotating filter assembly rotates. Since the valve core needs to rotate frequently to achieve different functions, ordinary sealing rings are difficult to meet the sealing requirements during the rotation process. However, the rotating O-ring has good elasticity and wear resistance, and can deform with the rotation of the valve core, always maintaining the sealing effect and preventing liquid leakage during rotation.
[0015] The present invention is further configured such that both the drain port end cap and the lower connecting end cap are installed on the valve body in a detachable connection manner.
[0016] The above technical solution, employing a detachable connection method, allows staff to quickly open the end cover and directly inspect key components inside the valve body, such as rotating filter components, sealing rings, and rotating O-rings. If any problems are found, timely repairs or cleaning can be carried out, saving a significant amount of time and effort spent on dismantling complex connection structures, reducing equipment downtime, and improving production efficiency.
[0017] The present invention is further configured such that a sealing gasket is provided at the connection between the drive shaft end cover and the three-position actuator.
[0018] Through the above technical solution, the sealing gasket can effectively prevent dust, debris and other contaminants from entering the three-position actuator. With the sealing gasket, the inside of the actuator can be kept clean, ensuring its stable operation.
[0019] The beneficial effects of this utility model are as follows:
[0020] 1. This utility model designs a rotating filter assembly with a particle filtration zone at the top of the valve core. With the help of a three-position actuator, the rotation of the valve core can be precisely controlled after the material reaction is completed, achieving efficient solid-liquid separation. The particle filtration zone traps particulate solids, while the liquid flows into the recovery device from port C through the liquid channel. After solid-liquid separation is completed, the valve core rotates to different positions to achieve particle discharge and reactor cleaning functions. It is simple to operate and has a high degree of functional integration.
[0021] 2. This utility model connects the valve body to the main equipment via a quick-release chuck. During installation, only simple alignment of the interface is required, eliminating the need for complex tools, significantly shortening installation time and improving work efficiency. The drain port end cap and the lower connection end cap are detachable, facilitating quick opening of the end caps for direct observation, inspection, repair, and cleaning of key components inside the valve body, such as the valve core assembly, sealing ring, and rotating O-ring. This saves the time and effort required to dismantle complex connection structures, reduces equipment downtime, and lowers maintenance costs. Attached Figure Description

[0027] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.
[0028] Please see Figures 1-3A hemispherical valve with filtration and cleaning function includes a valve body 1. The valve body 1 is connected to the main equipment via a quick-release chuck. The quick-release chuck connection requires no complicated tools or operating procedures. The operator only needs to align the quick-release chuck of the valve body 1 with the corresponding interface on the main equipment, and then complete the connection through a simple operation, which greatly shortens the installation time and improves work efficiency. The inner wall of the valve body 1 is provided with an anti-scaling coating, and the outer wall of the valve body 1 is provided with a heat insulation layer. The anti-scaling coating can reduce the surface roughness of the inner wall of the valve body 1, making it difficult for materials to adhere, reducing material residue, avoiding blockage problems caused by material residue, and ensuring the normal flow capacity of the valve. The heat insulation layer on the outer wall of the valve body 1 can effectively reduce heat loss or external heat transfer, keep the material within a suitable temperature range, reduce energy waste, and reduce production costs. The outer wall of the valve body 1 has ports A 2 and B 3 at the top and bottom positions, respectively, and ports C 4 and D 5 are also provided.
[0029] like Figure 4 As shown, a rotating filter assembly 6 is provided inside the valve body 1. The rotating filter assembly 6 includes a valve core 601 rotatably connected inside the valve body 1. A particle filtration zone 602 is provided on the top of the valve core 601. Liquid channels 603 and two mounting seats 604 are respectively opened inside the valve core 601. A sealing ring 7 and multiple rotating O-rings 8 are respectively installed between the rotating filter assembly 6 and the valve body 1. The sealing ring 7 is located at the circumferential position where the rotating filter assembly 6 contacts the valve body 1. The multiple rotating O-rings 8 are distributed at intervals along the rotational direction of the rotating filter assembly 6. The sealing rings 7 located at the circumferential position where the rotating filter assembly 6 contacts the valve body 1 are... The O-ring 7 forms a tight sealing barrier between the two, effectively preventing liquid from seeping out from the contact gap between the rotating filter assembly 6 and the valve body 1 during solid-liquid separation and cleaning. Multiple rotating O-rings 8 are spaced apart along the rotation direction of the rotating filter assembly 6, providing a continuous and effective seal when the rotating filter assembly 6 rotates. Since the valve core 601 needs to rotate frequently to achieve different functions, ordinary sealing rings 7 are difficult to meet the sealing requirements during rotation. However, the rotating O-rings 8 have good elasticity and wear resistance, and can deform with the rotation of the valve core 601, always maintaining the sealing effect and preventing liquid leakage during rotation.
[0030] like Figure 4As shown, after the material reaction is complete, the three-position actuator 12 drives the valve core 601 to rotate to a specific position, so that the particle filtration zone 602 at the top of the valve core 601 corresponds to port A 2 of the valve body 1, opening the valve connected to the drain port C 4. The solid-liquid mixture flows to the valve core 601 under pressure or gravity. The particle filtration zone 602 traps the particulate solids, while the liquid enters the liquid channel 603 inside the valve core 601 through the pores of the particle filtration zone 602, and then flows into the liquid recovery device from port C 4 through the liquid channel 603, thereby achieving solid-liquid separation. When it is necessary to discharge the trapped particulate solids, the three-position actuator 12 controls the valve core 601 to rotate 90 degrees, so that the valve core 601 is in the position of the drain port D 5. The upper port A 2 and the lower port B 3 of the valve body 1 are connected. The particulate solids rely on their own gravity to fall from port A 2 through the channel between the valve core 601 and the valve body 1 into the drain port connected below. In the granulation device, port B3 is connected to the device to complete the discharge of granular solids. After the material discharge is completed, the three-position actuator 12 controls the valve core 601 to rotate another 90 degrees, for a total rotation of 180 degrees, so that the valve core 601 is at the lower port B3. At this time, the upper port A2 and the drain port D5 are connected, and cleaning liquid is injected into the reaction device, such as the reactor. The cleaning liquid cleans the reactor. The wastewater generated during cleaning enters the channel between the valve core 601 and the valve body 1 through port A2, and then is discharged into the sewage pipe from port D5, thus realizing the cleaning function of the reactor. The two mounting seats 604 inside the valve core 601 are used to install the bearing 9 and cooperate with the bearing 9 installed inside the valve body 1. This structural design ensures the stability and smoothness of the rotation of the valve core 601 inside the valve body 1, reduces friction and wear during the rotation process, and ensures that the valve core 601 can be accurately rotated to different positions, reliably realizing the functions of solid-liquid separation, material discharge and cleaning.
[0031] like Figures 1-3 As shown, a bearing 9 is installed inside the valve body 1, and a drain port end cap 10 corresponding to port C 4 is installed on the outer wall of the valve body 1. Both the drain port end cap 10 and the lower connecting end cap 11 are installed on the valve body 1 in a detachable manner. This detachable connection method allows operators to quickly open the end caps and directly observe and inspect key components inside the valve body 1, such as the rotating filter assembly 6, the sealing ring 7, and the rotating O-ring 8. Once a problem is found, it can be repaired or cleaned in a timely manner, saving the time and effort required to dismantle complex connection structures. To reduce equipment downtime and improve production efficiency, the valve body 1 has a lower end cap 11 corresponding to port B 3 installed on its outer wall. A three-position actuator 12 is installed on one side of the valve body 1. A drive shaft end cap 13 is installed on the outer wall of the valve body 1 near the three-position actuator 12. A sealing gasket is provided at the connection between the drive shaft end cap 13 and the three-position actuator 12. The sealing gasket can effectively prevent dust, debris and other contaminants from entering the interior of the three-position actuator 12. With the sealing gasket, the interior of the actuator can be kept clean, ensuring its stable operation.
[0032] In use, the valve body 1 has port A2 connected to the corresponding reaction device, port B3 connected to the device for discharging fixed particles, port C4 connected to the residual liquid recovery pipe after reaction, and port D5 connected to the wastewater discharge pipe after cleaning. During the material reaction, the valve core 601 is in the closed state and is located at port A2. After the material reaction is completed, the three-position actuator 12 drives the valve core 601 in the rotating filter assembly 6 to rotate, so that the particle filtration zone 602 at the top of the valve core 601 corresponds to port A2 of the valve body 1, opening the valve connected to the drain port C4. Under the action of pressure or gravity, the solid-liquid mixture flows to the valve core 601. The particle filtration zone 602 at the top of the valve core 601 plays a interception role, preventing the particle solids from passing through, while the liquid passes through the pores of the particle filtration zone 602 and enters the liquid channel 603 inside the valve core 601, and finally flows into the liquid recovery device through port C4, thereby achieving solid-liquid separation.
[0033] When it is necessary to discharge the retained particulate solids, the three-position actuator 12 controls the valve core 601 to rotate 90 degrees, so that it is in the position of the drain port D5. The upper part A2 and the lower part B3 of the valve body 1 are connected. The particulate solids rely on their own gravity to fall from A2 through the channel between the valve core 601 and the valve body 1 into the discharge and fixing particulate device connected to B3 below, thus completing the discharge of particulate solids.
[0034] After the material discharge is completed, the three-position actuator 12 controls the valve core 601 to rotate 90 degrees, so that the valve core 601 is at the lower B port 3, and the upper A port 2 and the sewage outlet D port 5 are connected, injecting cleaning liquid into the reaction device. The cleaning liquid cleans the reactor, and the sewage generated by cleaning enters the channel between the valve core 601 and the valve body 1 through A port 2, and then is discharged into the sewage pipe from D port 5, thus realizing the cleaning function of the reactor.
[0035] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
