[0002] In fields such as the petrochemical industry, the food and medicine hygiene industry, the rubber industry, and the special vehicle industry, conveying pipelines are widely used to control the flow of fluids, regulate pressure and flow rate to ensure the stability of the production process and product quality. In these applications, conveying pipelines usually need to handle media containing particles, impurities, corrosive substances, or high-viscosity fluids. Therefore, material accumulation often occurs inside the conveying pipelines, resulting in blockage or contamination, which affects the overall performance of the system. Therefore, the design of conveying pipelines that can be conveniently cleaned internally is of great significance in these fields.

[0003] In the existing design of conveying pipelines, many conveying pipelines are inconvenient to clean, with complex internal structures. Multiple components need to be disassembled to carry out effective cleaning, resulting in long maintenance time and large workload, which affects the operating efficiency of the equipment. At the same time, there is often a lack of effective isolation measures between the flow path and the cleaning channel of traditional conveying pipelines. During the cleaning process, residual materials may mix into the cleaning water, causing cross-contamination and unable to ensure the purity of the cleaning effect. This situation is particularly prominent in application scenarios that require frequent cleaning, directly affecting the reliability and service life of the equipment. Summary of the Utility Model

[0004] The purpose of the embodiments of the utility model is to provide a multi-functional slide valve that can be washed with water, aiming to solve the technical problems mentioned in the background art.

[0021] In order to make the objectives, technical solutions, and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0022] The following describes the specific implementation of the present utility model in detail in conjunction with specific embodiments.

[0023] As Figures 1-5 shown, a water-washable multi-functional slide valve provided by an embodiment of the present utility model includes an upper valve body 1 and a lower valve body 9, and the upper valve body 1 and the lower valve body 9 are arranged along the same axis.

[0024] A mounting frame 12 is provided on the surface of the upper valve body 1, and a cylinder 13 is mounted on the surface of the mounting frame 12. One end of the cylinder 13 is connected to a driving block 11. The cylinder 13 is a driving component mounted on the mounting frame 12 on the surface of the upper valve body 1 for providing linear driving force. The cylinder 13 is connected to the driving block 11 at one of its ends, thereby realizing the operation of opening, closing, or adjusting the valve.

[0025] An upper valve body fixing ring 5 is sleeved on the outer side of the upper valve body 1 near the lower valve body 9, and a lower valve body fixing ring 6 is sleeved on the outer side of the lower valve body 9 near the upper valve body 1.

[0026] A first sealing washer 14, a second sealing washer 15, and a third sealing washer 16 are sequentially arranged from top to bottom between the upper valve body fixing ring 5 and the lower valve body fixing ring 6, and a valve port is provided on the side surface of the second sealing washer 15. A valve plate 10 is movably connected inside the valve port, and one end of the driving block 11 is connected to the surface of the valve plate 10.

[0027] Three sealing washers form an effective sealing effect through the pressing force between the upper valve body fixing ring 5 and the lower valve body fixing ring 6. The upper valve body fixing ring 5 is sleeved on the outer side of the upper valve body 1 near the lower valve body 9, and the lower valve body fixing ring 6 is sleeved on the outer side of the lower valve body 9 near the upper valve body 1. They are connected by a detachable threaded connection or using fasteners such as bolts and nuts between them. This connection method ensures the pressing effect between the fixing rings, firmly presses the three sealing washers together, prevents leakage, and ensures the sealing inside the valve body.

[0028] The material selection of the sealing washers is crucial. Usually, materials with corrosion resistance, high temperature resistance, and wear resistance are used, such as Viton fluororubber, PTFE (polytetrafluoroethylene), commonly known as Teflon, and other high-performance elastomers. These materials have excellent chemical corrosion resistance and heat resistance, and can resist the erosion of fluids and temperature changes during valve operation, maintaining a long-term sealing effect.

[0029] In addition, the multiple settings of the sealing washers, the first sealing washer 14, the second sealing washer 15, and the third sealing washer 16 enhance the sealing effect. Especially, the second sealing washer 15 is provided with a valve port on its side for connecting the valve plate 10. This design allows the valve plate to move freely during operation while maintaining a tight seal at the valve port, effectively preventing leakage problems during the movement of the valve plate. Through appropriate material selection and connection methods, this sealing structure ensures the reliable sealing of the valve body and long-term stable operation.

[0030] The surface of the upper valve body 1 is provided with a water passage port 17, and a cleaning cylinder 4 is arranged at a position on the surface of the upper valve body 1 near the water passage port 17. A connecting cylinder 8 is arranged on the outer side of the cleaning cylinder 4, and a water injection pipe 7 is connected to the outer side of the connecting cylinder 8.

[0031] The water injection pipe 7 is connected to the inside of the connecting cylinder 8, the connecting cylinder 8 is connected to the inside of the cleaning cylinder 4, and the cleaning cylinder 4 is connected to the inside of the water passage port 17. The water injection pipe 7 can be connected to an external water source, and a control valve is arranged on it for regulating and controlling the on-off and flow rate of the water flow.

[0032] In an embodiment of the present utility model, the purpose is to fully wash and clean the inner wall of the upper valve body 1 and the conveying pipeline connected to the upper valve body 1.

[0033] The flow direction of the material is from the upper valve body 1 into the lower valve body 9. When it is necessary to clean the inner wall of the upper valve body 1 and the conveying pipeline connected to the upper valve body 1, it should first be ensured that no more material flows into the upper valve body 1.

[0034] After that, start the cylinder 13, and one end of it drives the valve plate 10 to move between the first sealing washer 14 and the third sealing washer 16. At this time, the valve plate 10 intercepts the flow port between the upper valve body 1 and the lower valve body 9.

[0035] When the valve plate 10 is in the closed and blocking state, if it is necessary to wash the inside of the upper valve body 1, external cleaning water can be injected into the water injection pipe 7. The cleaning water flows into the inside of the upper valve body 1 through the water injection pipe 7, the connecting cylinder 8, the cleaning cylinder 4 and the water passing port 17 in sequence, and cleans the inner wall of the upper valve body 1 and the conveying pipeline connected to the upper valve body 1. Since the valve plate 10 has been closed and blocked the material flow path, the cleaning water and sewage in the upper valve body 1 will not enter the lower valve body 9, ensuring the purity of the cleaning effect. After the cleaning is completed, the sewage can be discharged reversely through the water injection pipe 7 to complete the entire cleaning process.

[0036] In summary, this technical solution has significant beneficial effects, which are mainly reflected in the high efficiency and safety of its cleaning and flow control. When the valve plate 10 is in the closed state, the cleaning water can be injected from the outside into the water injection pipe 7 and flow into the inside of the upper valve body 1 through the connecting cylinder 8 and the water passing port 17 in sequence to thoroughly clean the inner wall of the valve body. During the cleaning process, due to the effective plugging and sealing of the valve plate 10, the cleaning water is prevented from entering the lower valve body 9. This design makes the cleaning process independent of the material flow path, avoiding the pollution of the cleaning water by the material, thereby improving the purity of the cleaning effect. At the same time, the effective sealing design of the valve plate reduces the requirements for manufacturing and installation accuracy of the system, simplifies the production process, and reduces the maintenance cost. Overall, this technical solution realizes the organic combination of flow control and cleaning functions, improves the reliability, operation simplicity and operation efficiency of the equipment, and is applicable to various fluid control systems that require cleaning functions.

[0037] In this embodiment, the valve plate 10 is arranged between the upper valve body 1 and the lower valve body 9 at an inclined angle. Through this inclined design, the flow direction and flow rate of the cleaning water can be effectively guided, making the cleaning water enter the inside of the upper valve body 1 more smoothly. Overall, this design enhances the control accuracy and reliability of the valve, making it applicable to different fluid control application environments.

[0038] In this embodiment, a hinge is installed on the surface of the cleaning cylinder 4, and the cleaning cylinder 4 is rotatably connected to the sealing cover plate 3 through the hinge. A sealing connection state is maintained between the sealing cover plate 3 and the cleaning cylinder 4 through a sealing ring or gasket. When the cover plate is closed, the sealing ring or gasket is pressed under the action of the locking device to ensure airtightness and liquid tightness. At the same time, the sealing cover plate 3 can be firmly locked with the cleaning cylinder 4 through a simple buckle or bolt structure, which is convenient for quick opening and closing. The hinge design makes the operation of the sealing cover plate 3 simple when opening and closing, and maintenance and cleaning can be carried out without completely disassembling the components.

[0039] By setting the sealing cover plate 3, it is possible to conveniently open the cleaning cylinder 4 during equipment cleaning, maintenance or troubleshooting, and facilitate a thorough cleaning of the interior of the cleaning cylinder 4, the water injection pipe 7 and the connecting cylinder 8, ensuring that there are no residues or contaminants inside the equipment and maintaining the normal operation of the equipment. The sealing cover plate 3 is made of a transparent material, allowing users to directly observe the condition inside the cleaning cylinder 4 through the cover plate, promptly detect possible blockages or contaminants, thereby reducing unnecessary disassembly times and improving the maintenance efficiency and the operational safety of the equipment.

[0040] This design not only improves the convenience of cleaning and maintenance but also ensures the system's sealing performance and operational safety, enabling the equipment to have higher reliability and operational efficiency under complex working conditions.

[0041] In this embodiment, an installation panel 2 is sleeved outside the upper valve body 1, and a number of reserved installation holes are provided on the surface of the installation panel 2, thus facilitating the fixing of the valve body on the support structure of a pipeline or equipment. Through these reserved installation holes, bolts, nuts or other fasteners can be used to firmly install the upper valve body 1 in a predetermined position, ensuring the stability and reliability of the valve during operation. At the same time, the positions and quantities of these reserved installation holes are optimized in design, capable of adapting to different installation requirements, providing a more flexible installation method, and facilitating installation and maintenance under various working conditions.

[0042] This design not only improves the adaptability and easy installability of the equipment but also simplifies the on-site installation process, reduces the installation time and maintenance costs, and ensures the safety and stability of the equipment operation.

[0043] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
