Description

Technical Field

[0001] The utility model belongs to the technical field of filter joints, and in particular relates to a joint used for installing a filter. Background Art

[0002] In the process of liquid flow, especially in industrial applications, the liquid often contains various particles, impurities and sediments. If these impurities are not effectively filtered, they may not only block the pipeline and affect the flow, but also cause wear or damage to the precision parts inside the system. By installing a filter joint, the impurities in the liquid can be effectively intercepted and removed, thereby ensuring the normal operation of the system and extending its service life;

[0003] However, the existing integrated filter joint design also brings some challenges, especially in terms of cleaning and maintenance of the filter;

[0004] First, the integrated design of the filter connector does enhance its compactness and ease of installation. However, this design also makes it relatively difficult to regularly clean the internal filter and accumulated filter material. Since the filter is usually located inside the filter connector and the entire device is closed, users cannot directly access the filter for cleaning or replacement.

[0005] Over time, the filter will gradually accumulate a large amount of particles and impurities, resulting in a gradual reduction in the filtration effect. This will not only affect the purity of the outflowing liquid, but may also cause a reduction in water flow and even block the pipes, thus affecting the normal operation of the entire system. Utility Model Content

[0006] The utility model provides a joint for filter installation, aiming to solve the problem of existing filter joints that the filter screen is located in a closed interior and is difficult for users to directly touch, resulting in difficulty in cleaning and replacing the filter screen. After long-term use, the filter screen is prone to accumulate impurities, reducing the filtering effect and even affecting the water flow and normal operation of the system.

[0007] The utility model is implemented as follows: a joint for filter installation, comprising a valve body; connecting ends arranged at the two end sides of the valve body, a filtering channel for liquid flow is formed between the two connecting ends; a connecting component arranged outside the two connecting ends; the connecting component comprises: a joint, the joint is a cylindrical setting with two ends connected; an external thread groove arranged on the outer edges of the ends on both sides of the joint; an internal thread groove arranged on the inner side of the connecting end, the connecting end and the joint are threadedly matched; an assembly groove arranged on the inner side of the joint, the assembly groove is an annular setting; a fixing ring arranged in the assembly groove; a sealing gasket arranged on the outer side of the fixing ring; a filter seat arranged on the outer side of the fixing ring; a filter screen arranged on the outer side of the filter seat.

[0008] Preferably, a plurality of connection blocks are arranged on one side of the filter screen, a plurality of connection slots adapted to the connection blocks are opened on the filter seat, and the connection blocks are engaged with the connection slots.

[0009] Preferably, a valve stem is disposed at an upper position of the inner cavity of the valve body, a first valve flap is disposed at a bottom of the valve stem, and a second valve flap is disposed at a bottom position of the inner cavity of the valve body.

[0010] Preferably, a lock core connected to the valve stem is provided at the top of the valve body, and a matching key is provided in the lock core.

[0011] Preferably, an annular protrusion is provided on the outer side of the sealing gasket, and an annular groove matching the protrusion is provided on the inner wall of the assembly groove.

[0012] Preferably, the outer diameter of the sealing gasket matches the inner diameter of the assembly groove.

[0013] Preferably, the winding ratio of the internal thread groove is consistent with the winding ratio of the external thread groove.

[0014] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0015] First, by providing connectors with filter seats on the outside of the two connecting ends, the device ensures that the liquid can be filtered for the first time before flowing through the valve body and can be filtered for the second time after flowing out of the valve body, thereby efficiently removing impurities and particulate matter therein. This double filtering mechanism significantly improves the filtering effect and ensures the purity of the outflowing liquid so that it meets the filtering requirements.

[0016] Second: The device adopts a threaded connection method between the joint and the connection end, which is not only stable and reliable, but also convenient for subsequent installation and disassembly while ensuring the sealing performance. In addition, the quick disassembly design of the filter allows users to easily replace or clean the filter, thereby simplifying the maintenance process. This convenience improves work efficiency, reduces maintenance costs, and brings users a better user experience.

[0017] Third: This device can effectively prevent the valve from being opened or closed at will through the cooperation of the key and the lock core. This design improves the safety of valve operation and avoids accidents. At the same time, by adjusting the rotation of the lock core, the opening degree of the valve can be accurately controlled, thereby achieving the adjustment of the fluid flow. This provides users with more flexibility and meets the flow control needs in different application scenarios. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0026] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0027] The utility model embodiment provides a connector for filter installation, such as Figure 1-6As shown, it includes a valve body 1; connecting terminals 2 provided at two end sides of the valve body 1, and a filtering channel for liquid flow is formed between the two connecting terminals 2; a connecting component provided on the outside of the two connecting terminals 2; the connecting component includes: a joint 3, which is a cylindrical setting with two terminals connected; an external thread groove 4 provided on the outer edges of the terminals on both sides of the joint 3; an internal thread groove 5 provided on the inner side of the connecting terminal 2, and the connecting terminal 2 and the joint 3 are threadedly matched; an assembly groove 6 provided on the inner side of the joint 3, and the assembly groove 6 is an annular setting; a fixing ring 7 provided in the assembly groove 6; a sealing gasket 8 provided on the outside of the fixing ring 7; a filter seat 9 provided on the outside of the fixing ring 7; and a filter screen 10 provided on the outside of the filter seat 9.

[0028] It should be noted that, since the existing filter connector 3 has a closed filter screen 10, it is difficult for users to directly access it, which makes it difficult to clean and replace the filter screen 10. After long-term use, the filter screen 10 is prone to accumulate impurities, reducing the filtering effect and even affecting the water flow and normal operation of the system. This solution achieves double filtration of the liquid through a double filtering mechanism, ensuring the effect of liquid filtration. At the same time, the threaded connection and quick disassembly design are used to simplify the installation and maintenance process, realize the rapid replacement or other operations of the internal parts of the connector 3, and use the safety locking function to achieve precise flow control, thereby improving the overall safety and flexibility of use.

[0029] Specifically, in this embodiment, the scheme mainly includes a valve body 1; when liquid needs to pass through the filter, it will flow in from one end of the valve body 1, and then pass through the filtering channel formed by the connecting end 2, and flow smoothly to the other end; in this process, the joint 3 plays a key guiding and restraining role, ensuring the directionality and stability of the liquid flow, thereby ensuring the realization of the filtering effect; the external thread groove 4 of the joint 3 is tightly matched with the internal thread groove 5 of the connecting end 2, and the firmness and stability of the joint 3 are ensured by threaded connection; this design not only ensures that the joint 3 is not easy to loosen or fall off under high pressure or high flow rate, but also facilitates the installation and disassembly process and improves work efficiency; a sealing gasket 8 is provided on the outer side of the fixing ring 7; when the joint 3 is tightly connected to the connecting end 2, the sealing gasket 8 can effectively prevent the liquid from leaking between the joint 3 and the connecting end 2, thereby ensuring the sealing of the filtering system;

[0030] A filter screen 10 is provided in the filter seat 9. When the liquid flows through the filter joint 3, it will pass through the filter screens 10 in the two joints 3 in turn. This double filter screen 10 design can effectively remove impurities and particulate matter in the liquid, thereby ensuring that the final outflowing liquid meets the use requirements and effectively guarantees the purity of the liquid. The fixing ring 7 is located in the assembly groove 6, which provides stable support for other components such as the sealing gasket 8 and the filter seat 9; the annular design of the assembly groove 6 enables all components to be assembled together in an orderly manner to form a compact and stable whole; this design not only improves the structural strength of the joint 3, but also facilitates subsequent maintenance and cleaning work.

[0031] In a further preferred embodiment of the present invention, Figure 4 As shown, a plurality of connection blocks 16 are disposed on one side of the filter screen 10 , and a plurality of connection slots 17 adapted to the connection blocks 16 are opened on the filter seat 9 , and the connection blocks 16 are engaged with the connection slots 17 .

[0032] Preferably, after accurately aligning the connecting block 16 on the filter 10 with the connecting slot 17 on the filter seat 9, the connecting block 16 can be easily snapped into the corresponding connecting slot 17, thereby forming a stable and firm snap-fit. This snap-fit ​​method ensures that the filter 10 can be tightly and reliably fixed on the filter seat 9, which not only ensures the stability of the filter 10 during the filtration process and prevents it from shifting or falling off, but also provides necessary support for the filter 10. When the filter 10 needs to be replaced or cleaned, the user only needs to perform simple operations to easily pull out the connecting block 16 from the connecting slot 17 to achieve rapid disassembly of the filter 10. This design greatly simplifies the user's daily maintenance process for the filter 10 and improves the usability and maintainability of the equipment.

[0033] In a further preferred embodiment of the present invention, Figure 3 As shown, a valve stem 11 is disposed at the upper position of the inner cavity of the valve body 1 , a first valve flap 12 is disposed at the bottom of the valve stem 11 , and a second valve flap 13 is disposed at the bottom position of the inner cavity of the valve body 1 .

[0034] In this embodiment, when the valve body 1 is in a closed state, the valve stem 11 drives the first valve flap 12 to move downward. At this time, the first valve flap 12 and the second valve flap 13 fit tightly together to form an effective seal to prevent the medium from passing through. When the valve body 1 needs to be opened, the valve stem 11 is in its highest position, so that the valve stem 11 is away from the second valve flap 13 to allow the medium to flow through.

[0035] In a further preferred embodiment of the present invention, Figure 2-3 As shown, a lock core 14 connected to the valve stem 11 is disposed at the top of the valve body 1 , and a matching key 15 is disposed in the lock core 14 .

[0036] In this embodiment, when the correct key 15 is inserted into the lock cylinder 14, the cutting edge of the key 15 matches the gear or drive plate inside the lock cylinder 14, and the lock cylinder 14 can be rotated at this time. Due to the connection between the lock cylinder 14 and the valve stem 11, rotating the lock cylinder 14 will cause the valve stem 11 to move up and down, thereby changing the opening degree of the valve, and then adjusting the flow rate of the fluid to prevent it from being opened or closed at will. This design not only improves the safety of valve operation, but also facilitates the management and maintenance of the valve.

[0037] In a further preferred embodiment of the present invention, Figure 4 As shown, the outer side of the sealing gasket 8 is provided with an annular protrusion, and the inner wall of the assembly groove 6 is provided with an annular groove matching the protrusion.

[0038] In this embodiment, when the sealing gasket 8 is compressed, the annular protrusion can be embedded in the annular groove to form a more secure sealing structure, and also enhance the structural strength of the joint 3, which enables the joint 3 to maintain a stable sealing effect under high pressure or high flow rate, thereby ensuring the normal operation of the filtration system.

[0039] In a further preferred embodiment of the present invention, Figure 4 As shown, the outer diameter of the sealing gasket 8 is matched with the inner diameter of the mounting groove 6 .

[0040] In this embodiment, when the sealing gasket 8 is placed in the assembly groove 6, its outer diameter matches the inner diameter of the assembly groove 6, so that the gasket can be evenly stressed and fit tightly against the inner wall of the groove. This tight fit can effectively prevent liquid or gas from leaking out through the gap of the assembly groove 6.

[0041] In a further preferred embodiment of the present invention, Figure 3 As shown, the winding ratio of the internal thread groove 5 is consistent with the winding ratio of the external thread groove 4.

[0042] In this embodiment, it is ensured that the connection end 2 and the connector 3 can be screwed in smoothly and continuously, thereby achieving a good threaded connection effect.

[0043] Working principle: When liquid needs to pass through the filter, it will first flow in from one end of the valve body 1. The two end sides of the valve body 1 are provided with connecting ends 2, and a filtering channel for the liquid is formed between the two connecting ends 2; when the liquid flows through this channel, it will maintain its directionality and stability;

[0044] The two ends of the connector 3 are connected cylindrical structures; external thread grooves 4 are provided on the outer edges of the two side ends of the connector 3, and these external thread grooves 4 are tightly matched with the internal thread grooves 5 on the inner side of the connecting end 2; through this threaded connection method, the connector 3 is firmly connected to the connecting end 2, which not only ensures the stability of the connection, but also facilitates the subsequent installation and disassembly process;

[0045] On the inner side of the joint 3, there is an assembly groove 6, which is an annular structure for orderly assembling other components; the fixing ring 7 is located in the assembly groove 6, providing stable support for subsequent components such as the sealing gasket 8 and the filter seat 9; in particular, the sealing gasket 8 can effectively prevent the liquid from leaking at the joint 3 when the joint 3 is tightly connected to the connecting end 2, thereby ensuring the sealing of the entire filtering system;

[0046] The filter seat 9 is the core part of the filtration system, and a filter screen 10 is arranged inside it; when the liquid flows through the joint 3, it will pass through the two filter screens 10 in sequence; this double filter screen 10 design can effectively remove impurities and particulate matter in the liquid, ensuring that the outflowing liquid meets the use requirements, thereby ensuring the purity of the liquid; in addition, the clamping method ensures that the filter screen 10 can be tightly and reliably fixed on the filter seat 9, which not only ensures the stability of the filter screen 10 during the filtration process and prevents it from shifting or falling off, but also provides necessary support for the filter screen 10. When the filter screen 10 needs to be replaced or cleaned, the user only needs to perform simple operations to easily pull out the connecting card block 16 from the connecting card slot 17, thereby realizing the rapid disassembly of the filter screen 10;

[0047] In addition, the filter joint 3 also has a safety locking function; when the correct key 15 is inserted into the lock core 14, the lock core 14 can rotate and move the valve stem 11 up and down through the connection with the valve stem 11; in this way, the opening degree of the valve can be accurately adjusted to control the flow rate of the fluid; this design not only prevents the valve from being opened or closed at will, improves safety, but also facilitates the management and maintenance of the valve;

[0048] Finally, regarding the design of the sealing gasket 8, when it is compressed, the annular protrusion thereon can be embedded in the annular groove of the joint 3 or the connecting end 2 to form a more secure sealing structure; this not only enhances the sealing effect, but also improves the structural strength of the joint 3, so that it can still maintain stable performance under high pressure or high flow rate.
