Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a hydraulic control valve with a filtering function. Background Art

[0002] A hydraulic control valve is a device used to regulate flow. Its principle is to control flow by increasing or decreasing the cross-sectional area of ​​the pipe. The hydraulic control valve can be controlled manually or automatically to adjust parameters such as flow and pressure. Specifically, when water flows through the hydraulic control valve, a pressure difference is formed. By changing the opening of the valve, the flow rate is changed to achieve hydraulic balance. Hydraulic control valves have a wide range of application scenarios in industrial production, domestic water use, etc.

[0003] Hydraulic control valves also have important applications in industrial wastewater treatment, tap water treatment and other fields, and can ensure the safety and stability of water flow. However, when traditional hydraulic control valves are used in tap water treatment, they are unable to filter suspended impurities such as grass in the water, causing grass impurities in the impurities to easily adhere to the space between the valve disc and the valve seat, thereby reducing the sealing between the valve disc and the valve seat.

[0020] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] See also Figure 1-6 , the utility model provides a technical solution:

[0022] A hydraulic control valve with a filtering function includes a hydraulic control valve body 1, which includes a groove flange 11. A water filter assembly 2 is threadedly installed at one end of the groove flange 11. The water filter assembly 2 includes a fixing sleeve 21. One end of the fixing sleeve 21 is threadedly installed inside the groove flange 11. An iron pipe 22 is fixedly installed at the other end of the fixing sleeve 21. A filter cylinder 24 is provided inside the cavity of the iron pipe 22. A first filter ring plate 23 is provided at the top end of one end of the filter cylinder 24. The first filter ring plate 23 is provided at the top end of the filter cylinder 24. A second filter ring plate 26 is provided at the bottom end of the filter cylinder 24. A guide plate 25 is fixedly installed between the first filter ring plate 23 and the second filter ring plate 26. A connecting pipe 27 is provided at the top end of the iron pipe 22.

[0023] In this embodiment, the hydraulic control valve body 1 is responsible for adjusting the flow and pressure according to demand. The groove flange 11 is threadedly arranged at one end of the hydraulic control valve body 1 for connecting and fixing the water filter assembly 2. The design of the groove flange 11 is convenient for installation and disassembly, and also provides sufficient strength and sealing. The fixing sleeve 21 of the water filter assembly 2 is threadedly installed inside the groove flange 11 for fixing and supporting the entire filter structure. The iron pipe 22 serves as a container for the filter cylinder 24. The iron pipe 22 is an external wire water guide pipe with threads at both ends. The iron pipe 22 has certain strength and corrosion resistance, which can protect the internal filter structure from damage. The filter cylinder 24 is composed of annular sheets for filtering impurities in the water. The first filter ring plate 23 and the second filter ring plate 26 are respectively arranged at the top and bottom ends of the filter cylinder 24 for supporting the filter medium and preventing it from leaking. The guide plate 25 is arranged between the first filter ring plate 23 and the second filter ring plate 26. Between the two filter ring plates 26, it is used to guide the water flow through the filter cylinder 24, ensuring that the water flow is evenly distributed and improving the filtration efficiency. The connecting pipe 27 is set at the top of the iron pipe 22, and is used to introduce the filtered water into the hydraulic control valve body 1. When the water flows through the hydraulic control valve body 1 with a filtering function, it is first filtered by the water filter assembly 2. Under the guidance of the guide plate 25, the water flows evenly through the filter cylinder 24, and the impurities therein are intercepted by the filter medium, while the clean water enters the hydraulic control valve body 1 through the connecting pipe 27 for flow and pressure regulation. The filtering function and the hydraulic control function are integrated into one, which simplifies the system structure and reduces the installation and maintenance costs. Through the reasonable design of the filter cylinder 24 and the selection of the filter medium, the suspended matter, organic matter and other impurities in the water can be effectively removed. By disassembling the groove flange 11 and the water filter assembly 2, the filter medium and damaged parts can be easily cleaned or replaced.

[0024] Specifically, the water inlet of the hydraulic control valve body 1 is provided with a groove flange 11 , and the groove flange 11 is threadedly installed with the fixing sleeve 21 .

[0025] In this embodiment, the water inlet is arranged at one end of the hydraulic control valve body 1 for receiving the water flow to be treated. The groove flange 11 is installed at the water inlet of the hydraulic control valve body 1, and a reliable connection with the pipeline is achieved through the groove connection technology. The design of the groove flange 11 is convenient for installation and disassembly, and also provides good sealing performance. The fixing sleeve 21 is installed inside the groove flange 11 through a threaded connection. The function of the fixing sleeve 21 is to support and fix the subsequent water filter assembly 2 to ensure the stability and reliability of the filtering structure. A threaded connection is adopted between the groove flange 11 and the fixing sleeve 21. The connection method has the advantages of simple structure, easy installation, and reliable connection. During installation, it is only necessary to screw the threaded part of the fixing sleeve 21 into the threaded hole of the groove flange 11 until the predetermined tightness is reached. When the filter medium needs to be cleaned or replaced, it is only necessary to remove the fixing sleeve 21 to easily access the water filter assembly 2, thereby reducing maintenance cost and time.

[0026] Specifically, a nut 221 is provided between the fixing sleeve 21 and the iron pipe 22 , and a fixing block 211 is provided inside the fixing sleeve 21 .

[0027] In this embodiment, the nut 221 is provided between the fixing sleeve 21 and the iron pipe 22 for fastening the two together. The nut 221 is usually used in conjunction with a bolt or a threaded rod. By rotating the nut 221, the clamping force between the fixing sleeve 21 and the iron pipe 22 is achieved, thereby ensuring the stability and reliability of the connection. One end of the fixing sleeve 21 may be provided with an external thread, and the corresponding end of the iron pipe 22 may be provided with a matching thread. During installation, the threaded portion of the fixing sleeve 21 is screwed into the threaded hole of the iron pipe 22 or the matching threaded portion, and then the nut is tightened. 221 is used to complete the connection. The connection method has the advantages of simple structure, reliable connection, and easy disassembly. The fixed block 211 is arranged inside the fixed sleeve 21 to fix and support the filter cylinder 24. The fixed block 211 may be made of elastic material to provide a certain clamping force when inserting the filter cylinder 24 to prevent it from loosening or falling off during use. The design of the fixed block 211 should facilitate the disassembly and replacement of the filter cylinder 24. When the filter cylinder 24 needs to be cleaned or replaced, the filter cylinder 24 can be easily removed by simply loosening the fixed block 211.

[0028] Specifically, there are several groups of filter cylinders 24 , and support rods 241 are provided between the filter cylinders 24 .

[0029] In this embodiment, the main function of the support rod 241 is to provide structural support to ensure that the multiple filter cylinders 24 can be stably arranged and fixed together. Through the support rod 241, the relative positions between the filter cylinders 24 are maintained, thereby avoiding possible displacement or deformation during the filtration process. The support rod 241 may also help to disperse the pressure on the filter cylinder 24 and improve the stability and durability of the entire filtration system.

[0030] Specifically, the first filter ring plate 23 is provided with a plurality of water flow troughs 231 .

[0031] In this embodiment, the design of the water flow trough 231 enables the water flow entering the filter cylinder 24 to be more evenly distributed, which helps to ensure that the filter medium can be fully utilized throughout the filter cylinder 24, thereby improving the filtration efficiency. By adjusting the number, size and distribution of the water flow troughs 231, the distribution of water flow can be further optimized to adapt to different filtration needs. The water flow trough 231 can guide the water flow through the filter cylinder 24 with less resistance, which helps to reduce pressure loss during the filtration process, thereby maintaining the stability and efficiency of the hydraulic control valve.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
