Description

Technical Field

[0001] This utility model relates to the field of filter valve technology, specifically a filter valve that is easy to clean. Background Technology

[0002] A filter valve, also known as a filter, is a device used to remove impurities from fluids. The working principle of a filter valve is relatively simple and effective. When fluid passes through the filter valve, it first enters the interior of the filter. The interior of the filter typically contains one or more layers of filter screens or filter media, the pore size of which is set according to the required filtration precision. Impurity particles in the fluid, because their size is larger than the filter screen pores, are intercepted on the surface or inside the filter screen, while clean fluid can pass through the filter screen smoothly and flow out from the filter outlet, thus achieving fluid filtration and purification.

[0003] The utility model disclosed in CN215293786U is a filter valve, which includes a valve body with an inlet hole and an outlet hole arranged on the same center line. The valve body has a water passage hole that connects the inlet hole and the outlet hole. A filter screen is installed in the water passage hole. A clamping connector is fixedly connected to the valve body at the inlet hole and the valve body at the outlet hole. The clamping connector has a convex ring on the outside and a groove on the inside of the clamping connector corresponding to the position of the convex ring. A sealing ring is installed in the groove, and the inner edge of the sealing ring extends out of the groove. It has the advantages of convenient connection and firm connection.

[0004] In the aforementioned filter valve, the filter screen is inverted, meaning that during filtration, the water flows upward through the filter screen and then flows out from the outlet on the other side. This arrangement causes most of the filtered impurities to tumble at the inlet end under the influence of gravity and water flow, preventing them from settling and collecting. This affects the filtration efficiency of the filter screen and also makes the filter valve easier to clean. Furthermore, due to the relatively thin wall of the filter screen, it is prone to deformation under pressure during use without the constraint of an auxiliary support structure, thus affecting its normal operation. Therefore, to address these issues, a filter valve that is easier to clean is proposed. Utility Model Content

[0005] The technical problem this utility model aims to solve is to provide a filter valve that is easy to clean. This filter valve has a vertically arranged assembled filter cylinder installed in an installation pipe. Water flows in from the inlet channel and then flows downwards through the assembled filter cylinder to complete filtration. This arrangement allows most impurities to accumulate at the bottom of the assembled filter cylinder under the impact of gravity and water flow, preventing them from affecting the filtration effect. It also facilitates subsequent cleaning. Furthermore, in the assembled filter cylinder, the top sealing sleeve and base constrain and support both ends of the cylinder body, effectively preventing deformation under pressure during use. During cleaning, the top sealing sleeve and base can be removed for thorough cleaning of the cylinder body. This solves the technical problems of comparative technologies, such as the difficulty in collecting and depositing filtered impurities, which affects both the filtration effect and the cleanliness of the filter valve, and the lack of auxiliary support structures leading to deformation of the filter cylinder under pressure during use, thus affecting its normal operation.

[0006] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0007] A filter valve designed for easy cleaning includes a valve body with an inlet pipe and an outlet pipe fixedly connected to its two ends, and an installation pipe at its bottom. The installation pipe has a filter chamber connected to the valve body, and the valve body has an inlet channel connecting the inlet pipe and the filter chamber. An assembled filter cartridge is inserted into the filter chamber, and a sealing cap is threaded onto the opening of the installation pipe to press the assembled filter cartridge tightly into the filter chamber. When the filter valve is in operation, water flows in from the inlet channel and then flows downward through the assembled filter cartridge to complete the filtration. This arrangement allows most impurities to accumulate at the bottom of the assembled filter cartridge under the impact of gravity and water flow, preventing them from affecting the filtration effect. It also facilitates subsequent cleaning. Cleaning the assembled filter cartridge is very convenient; simply unscrew the sealing cap and remove the assembled filter cartridge for cleaning.

[0008] In one possible implementation, the assembled filter cartridge includes a base with a mounting ring seat on its upper end face. The mounting ring seat is threadedly connected to the cartridge body, which has a plurality of arrayed filter holes. The top sealing sleeve constrains and supports the bottom end of the cartridge body, effectively preventing it from being deformed under pressure during use. Furthermore, the top sealing sleeve can be directly removed during cleaning, facilitating a thorough cleaning of the cartridge body.

[0009] In one possible implementation, the top of the filter chamber is provided with a convex ring, which forms an installation slot with the valve housing. The top of the cylinder body is snapped with a top sealing sleeve, the size of which matches the size of the installation slot. The top sealing sleeve constrains and supports the top of the cylinder body, effectively preventing it from being deformed under pressure during use. In addition, the top sealing sleeve can completely seal the installation slot, ensuring the sealing of the connection between the top of the cylinder body and the valve housing, and effectively preventing water from flowing out through the installation gap.

[0010] In one possible implementation, a sealing ring is fixedly provided on the inner wall of the mounting tube, the diameter of which matches the outer diameter of the mounting ring seat. When installing the assembled filter cartridge, the base and the sealing ring are pressed together to ensure the sealing of the connection and prevent water leakage.

[0011] In one possible implementation, a positioning ring is fixedly provided on the lower side of the closed ring, and a plurality of positioning grooves arranged in a circular array are opened on the inner wall of the positioning ring. The outer wall of the base is fixedly provided with positioning ridges corresponding to the positioning grooves. When the positioning ridges are inserted into the positioning grooves, the base cannot rotate due to the locking effect. At this time, even if the closed cover is turned, the base cannot be driven to rotate by friction, which can prevent the cylinder body from tortuous deformation under the action of torque.

[0012] In one possible implementation, the sealing cover includes a threaded cover that is threaded to the inner wall of the mounting tube, with a pressing protrusion fixedly provided on its upper end face and a lever fixedly provided on its lower end face. After the assembled filter cartridge is installed, the threaded cover is rotated by turning the lever, so that the pressing protrusion presses against the assembled filter cartridge, thereby completing the installation of the assembled filter cartridge.

[0013] In one possible implementation, a gap is left between the outer wall of the cylinder body and the filter chamber, and all the filter holes are located inside the filter chamber. This structure can ensure that all parts of the entire cylinder body can participate in the filtration work, thereby improving the filtration efficiency.

[0014] In summary, this utility model has the following beneficial technical effects:

[0015] The filter valve has a vertically arranged assembled filter cartridge installed in the installation pipe. Water flows in from the inlet channel and then flows downward through the assembled filter cartridge to complete the filtration. This arrangement allows most impurities to accumulate at the bottom of the assembled filter cartridge under the action of gravity, i.e. the impact of water flow, thus avoiding affecting the filtration effect and also facilitating subsequent cleaning.

[0016] In addition, in the assembled filter cartridge, the top sealing sleeve and the base can constrain and support both ends of the cartridge body, effectively preventing it from being deformed by pressure during use. Furthermore, the top sealing sleeve and the base can be removed for cleaning, making it easy to thoroughly clean the cartridge body. Attached Figure Description

[0023] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0024] like Figure 1 - Figure 2 As shown, this embodiment provides a filter valve that is easy to clean, including a valve body 1, with an inlet pipe 2 and an outlet pipe 3 fixedly connected to its two ends, and an installation pipe 4 at its bottom. The installation pipe 4 has a filter chamber 12 connected to the valve body 1, and the valve body 1 has an inlet channel 11 connected to the inlet pipe 2 and the filter chamber 12. An assembled filter cartridge 5 is inserted into the filter chamber 12, and a sealing cap 6 is threaded to the opening of the installation pipe 4 to press the assembled filter cartridge 5 into the filter chamber 12. When the filter valve is working, water flows in from the inlet channel 11 and then flows downward through the assembled filter cartridge 5 to complete the filtration. This arrangement allows most impurities to accumulate at the bottom of the assembled filter cartridge 5 under the action of gravity, i.e., the impact of the water flow, thus avoiding affecting the filtration effect. It also facilitates subsequent cleaning. Cleaning the assembled filter cartridge 5 is very convenient; simply unscrew the sealing cap 6 and remove the assembled filter cartridge 5 for cleaning.

[0025] like Figure 3As shown, the assembled filter cartridge 5 includes a base 51 with an mounting ring 52 on its upper end. A cartridge body 53 is threaded into the mounting ring 52, and several arrayed filter holes 54 are opened on it. The top sealing sleeve 55 constrains and supports the bottom end of the cartridge body 53, effectively preventing it from being deformed by pressure during use. When cleaning, the top sealing sleeve 55 can be directly removed, facilitating a thorough cleaning of the cartridge body 53. In addition, the top of the filter chamber 12 is provided with a protruding ring 13, which forms an installation slot 14 with the valve body 1. The top of the cartridge body 53 is snapped with the top sealing sleeve 55, the size of which matches the size of the installation slot 14. The top sealing sleeve 55 constrains and supports the top of the cartridge body 53, effectively preventing it from being deformed by pressure during use. In addition, the top sealing sleeve 55 can completely seal the installation slot 14, ensuring the sealing of the connection between the top of the cartridge body 53 and the valve body 1, effectively preventing water from flowing out through the installation gap.

[0026] like Figure 3 - Figure 4 As shown, a sealing ring 15 is fixedly installed on the inner wall of the mounting tube 4. The diameter of the ring matches the outer diameter of the mounting ring seat 52. When installing the assembled filter cartridge 5, the base 51 and the sealing ring 15 are pressed together to ensure the sealing of the connection and prevent water leakage. In addition, a positioning ring 17 is fixedly installed on the lower side of the sealing ring 15. Several positioning grooves 16 arranged in a circular array are opened on the inner wall of the positioning ring 17. The outer wall of the base 51 is fixedly installed with positioning ribs 56 corresponding to the positioning grooves 16. When the positioning ribs 56 are inserted into the positioning grooves 16, the base 51 cannot rotate due to the locking effect. At this time, turning the sealing cover 6 will not drive the base 51 to rotate through friction, which can prevent the cartridge body 53 from tortuous deformation under torque.

[0027] like Figure 3 As shown, the sealing cover 6 includes a threaded cover 61 that is threaded to the inner wall of the mounting tube 4. A pressing protrusion 62 is fixedly provided on its upper end face, and a lever 63 is fixedly provided on its lower end face. After the assembled filter cartridge 5 is installed, the threaded cover 61 is rotated by turning the lever 63, so that the pressing protrusion 62 presses against the assembled filter cartridge 5, thereby completing the installation of the assembled filter cartridge 5.

[0028] like Figure 2 As shown, there is a gap between the outer wall of the cylinder body 53 and the filter chamber 12, and all the filter holes 54 are located inside the filter chamber 12. This structure can ensure that all parts of the cylinder body 53 can participate in the filtration work, thereby improving the filtration efficiency.

[0029] The working principle and usage process of this utility model:

[0030] The filter valve has a vertically arranged assembled filter cartridge 5 installed in the installation pipe 4. Water flows in from the inlet channel 11 and then flows downward through the assembled filter cartridge 5 to complete the filtration. This arrangement allows most impurities to accumulate at the bottom of the assembled filter cartridge 5 under the action of gravity and water flow, thus avoiding affecting the filtration effect and facilitating subsequent cleaning. Cleaning the assembled filter cartridge 5 is also very convenient. Simply unscrew the sealing cap 6 and remove the assembled filter cartridge 5 for cleaning. After cleaning, simply insert the assembled filter cartridge 5 into the installation pipe 4 and then tighten the sealing cap 6 to complete the fixed installation.

[0031] In addition, in the assembled filter cartridge 5, the top sealing sleeve 55 and the base 51 can constrain and support both ends of the cartridge body 53, effectively preventing it from being deformed by pressure during use. Furthermore, the top sealing sleeve 55 and the base 51 can be removed during cleaning, making it easy to thoroughly clean the cartridge body 53.

[0032] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
