Description

Technical Field

[0001] This utility model relates to the technical field of an angle valve, and more specifically, to an angle valve with a filtering structure. Background Technology

[0002] Angle valves are crucial components in modern building water supply and drainage systems, widely used in homes, commercial buildings, and industrial facilities. They are primarily used to control the flow of water and regulate its volume, enabling precise water supply control for various water-using devices such as faucets, toilets, and water heaters.

[0003] However, the quality of current water supply is inconsistent, and various impurities easily mix into the water during transportation. From silt and algae at the source, to rust and metal debris from aging and corroding pipelines, as well as microorganisms and bacteria that thrive in the water, all can enter the angle valves and subsequent water-using equipment with the water flow. These impurities pose many hazards: on the one hand, large particles such as silt and debris can easily clog the small flow channels of the angle valves and the nozzles and valve cores of water-using equipment, leading to poor water flow or even flow interruption. For example, when a shower head is clogged with silt, the water flow becomes uneven and weak, seriously affecting the user experience; on the other hand, the long-term accumulation of impurities such as rust can react with chemicals in the water, accelerating the corrosion of internal metal parts of the equipment, shortening the service life of the equipment, and increasing maintenance and replacement costs. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an angle valve with a filtration structure that has excellent filtration effect and is easy to maintain.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an angle valve with a filtration structure, comprising a valve body having an inlet and an outlet, a water flow channel disposed within the valve body, and a valve stem assembly disposed within the valve body. The inlet and outlet are perpendicularly arranged, and the inlet is provided with an internal thread. The valve body is also provided with a filtration assembly threadedly connected to the inlet. The filtration assembly includes a filter housing with one open end and a hollow cylindrical body, a conical multilayer filter element disposed within the filter housing, and an elastic seal. The outer wall of the filter housing is provided with an external thread adapted to the internal thread of the inlet. The elastic seal is disposed at the connection between the filter housing and the valve body and between the layers of the filter element.

[0006] The present invention is further configured such that: the filter housing has a dual-channel structure, and each dual channel is provided with a filter element; the inner wall of the filter housing at the outlet end of the conical multi-layer filter element is provided with guide fins; the guide fins are non-uniformly arranged along the circumferential direction and have a spiral structure.

[0007] The present invention is further configured such that: the valve stem assembly includes a valve cover installed on the top of the valve body, a valve core disposed in the water flow channel, and a valve stem connected to the valve core; by rotating the valve cover, the opening and closing action of the valve core in the valve body can be controlled, thereby regulating the water flow.

[0008] The present invention is further configured such that: the filter element is provided with a coarse filter layer, a fine filter layer and an ion adsorption layer from the outside to the inside, the coarse filter layer is made of a large-pore metal mesh, and the fine filter layer is made of nanofiber filter material.

[0009] The present invention is further configured such that: the filter housing is made of transparent high-strength plastic material, which makes it easy to directly observe the pollution status of the filter element.

[0010] The present invention is further configured such that: the edge of the opening end of the filter housing is provided with an annular flange, and the annular flange is provided with a plurality of evenly distributed anti-slip grooves for manually rotating, disassembling and installing the filter housing.

[0011] The present invention is further configured such that: the valve cover is provided with an angle scale mark for intuitively displaying the opening and closing angle of the valve core.

[0012] The beneficial effects of this utility model are:

[0013] 1. The valve body's inlet and outlet are vertically aligned, aligning with pipeline installation requirements, saving space, and facilitating flexible layout. The filter assembly connects to the valve body's inlet via external threads; this detachable design greatly simplifies maintenance. The conical multi-layer filter cartridge has a large inlet diameter and a small outlet diameter, employing staged filtration to reduce pressure drop and prevent the filtration structure from increasing water flow resistance and affecting outlet pressure. When the filter cartridge needs cleaning or replacement due to excessive impurities, users can easily remove it from the valve body by simply rotating the filter housing, without the need for complex tools or professional technicians. The filter cartridges within the filtration assembly effectively intercept various impurities in the water, from large particles of silt and rust to fine microorganisms and colloids, ensuring cleaner water flowing from the outlet and significantly reducing the risk of damage to downstream water-using equipment. An elastic seal is installed at the connection between the filter housing and the valve body to ensure that the angle valve will not leak during operation. The elastic seal fits tightly against the filter housing and the valve body, effectively filling the gap between them, and maintaining good sealing even under water pressure fluctuations.

[0014] 2. The coordinated design of the valve cover, valve core, and valve stem in the valve stem assembly results in a smoother operation. When the user rotates the valve cover, the valve stem precisely controls the opening and closing of the valve core within the valve body, allowing for delicate adjustment of the water flow. Whether it's a precise trickle or a strong, unobstructed flow, it easily meets the water usage needs of different scenarios. The filter housing employs a dual-channel structure, with filter cartridges in both channels. The filter cartridges in the two channels work together; even if one channel's filter cartridge becomes partially clogged or slightly damaged, the other channel can still function normally, maintaining a certain filtration capacity. This ensures the angle valve continuously and stably provides filtered water, reducing water outages or water quality deterioration caused by sudden filter cartridge malfunctions, and guaranteeing the continuity and stability of water usage. The guide fins are non-uniformly arranged in a spiral structure along the circumference. When water flows through the filter element, the guide fins guide the water flow to form a spiral flow. This spiral flow method can make the water flow more evenly from the outlet, avoid the accumulation or turbulence of water in local areas, optimize the water flow path, and improve the stability and smoothness of the water flow.

[0015] 3. The filter cartridge consists of a coarse filtration layer, a fine filtration layer, and an ion adsorption layer, arranged sequentially from the outside to the inside, achieving deep purification of water. The coarse filtration layer, made of a large-pore metal mesh, can quickly intercept larger impurities in the water, such as sand, gravel, and rust, reducing the burden on subsequent fine filtration. The fine filtration layer, made of nanofiber filter material, effectively filters out fine particles, suspended solids, and some bacteria due to its tiny pores, significantly improving water purity. The ion adsorption layer adsorbs heavy metal ions, residual chlorine, and other harmful substances in the water, improving the taste and quality of the water and meeting people's higher requirements for healthy drinking water. It is especially suitable for direct drinking water systems or equipment with stringent water quality requirements. The filter housing is made of transparent, high-strength plastic, allowing direct observation of the filter cartridge's contamination status. Once the filter cartridge becomes darker in color or shows significant accumulation of impurities, it can be cleaned or replaced promptly to avoid excessive clogging affecting filtration efficiency and water flow rate. This proactive approach helps prevent malfunctions in water-using equipment caused by water quality issues, while also allowing for more efficient maintenance and lower maintenance costs.

[0016] 4. The filter housing features an annular flange and anti-slip grooves at the open edge, greatly facilitating manual rotation, disassembly, and installation. No additional tools are needed; simply use your fingers in close contact with the anti-slip grooves to easily rotate the filter. Whether for routine filter cleaning or replacement after its lifespan, the operation becomes easy and efficient. Even users with less strength or dexterity can complete the task smoothly, enhancing the convenience of user-managed angle valve maintenance. The angle scale markings on the valve cover allow users to intuitively understand the valve core's opening and closing angle, enabling precise water flow control. Users can adjust the valve core to the appropriate angle based on their actual water usage needs. For example, a larger water flow is needed when washing clothes; while a smaller water flow can be precisely controlled for delicate tasks such as watering plants. This meets the varying water flow requirements of different scenarios, avoiding inconvenience caused by excessive or insufficient water flow, and improving water efficiency and user experience.

[0021] Reference Figures 1 to 3 The embodiments of this utility model will be further described below.

[0022] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” are used in the embodiments to describe the relationship of one element or feature shown in the figures relative to another element or feature. It should be understood that, in addition to the orientations shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figures is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations. The device may be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0023] Moreover, relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.

[0024] Figures 1 to 3 The angle valve shown includes a filter structure, comprising a valve body 3 with an inlet 1 and an outlet 2, a water flow channel within the valve body 3, and a valve stem 8 assembly within the valve body 3. The inlet 1 and outlet 2 are vertically arranged to meet pipeline installation requirements, save space, and facilitate flexible layout. The inlet 1 has an internal thread. The valve body 3 also has a filter assembly threadedly connected to the inlet 1. The filter assembly includes a filter housing 4 with one open end and a hollow cylinder, a conical multi-layer filter element within the filter housing 4, and an elastic seal 5. The conical multi-layer filter element has a large inlet diameter and a small outlet diameter, providing staged filtration to reduce pressure drop and prevent the filter structure from increasing water flow resistance and affecting the outlet pressure. The outer wall of the filter housing 4 has an external thread that matches the internal thread of the inlet 1. The filter assembly is connected to the internal thread of the inlet 1 of the valve body 3 via the external thread. This detachable design greatly facilitates maintenance. When the filter element needs cleaning or replacement due to excessive impurities, the user can easily remove it from the valve body 3 by simply rotating the filter housing 4, without the need for complicated tools or professional technicians. The filter element in the filter assembly effectively intercepts various impurities in the water, including large particles of silt and rust, as well as tiny microorganisms and colloids, all of which are filtered layer by layer, making the water flowing from the outlet 2 cleaner and greatly reducing the risk of damage to downstream water-using equipment. The elastic seal 5 is located at the connection between the filter housing 4 and the valve body 3, and between the layers of the filter element, ensuring that the angle valve does not leak during operation. The elastic seal 5 fits tightly against the filter housing 4 and the valve body 3, effectively filling the gaps between them, maintaining good sealing even under fluctuating water pressure.

[0025] The filter housing 4 has a dual-channel structure 9, and each channel contains a filter element. The filter elements in the two channels cooperate with each other. Even if the filter element in one channel is partially blocked or slightly damaged, the other channel can still work normally, maintaining a certain filtration capacity. This ensures that the angle valve continuously and stably provides filtered water, reducing water outages or water quality deterioration caused by sudden filter element malfunctions, and guaranteeing the continuity and stability of water use. The inner wall of the filter housing 4 at the outlet end of the conical multi-layer filter element is provided with guide fins 14. The guide fins 14 are non-uniformly arranged in a spiral structure along the circumference. When water flows through the filter element, the guide fins 14 guide the water flow to form a spiral flow. This spiral flow allows the water to flow more evenly from the outlet 2, avoiding water accumulation or turbulence in local areas, optimizing the water flow path, and improving the stability and smoothness of the water flow.

[0026] The valve stem 8 assembly includes a valve cover 6 installed on the top of the valve body 3, a valve core disposed in the water flow channel, and a valve stem 8 connected to the valve core. When the user rotates the valve cover 6, the valve stem 8 can precisely control the opening and closing action of the valve core in the valve body 3, and achieve fine adjustment of the water flow. Whether it is a precise drip of small water flow or a smooth flow of large water flow, it can be easily achieved to meet the water use needs in different scenarios.

[0027] The filter element consists of a coarse filter layer 10, a fine filter layer 11, and an ion adsorption layer 12, arranged sequentially from the outside to the inside. This achieves deep purification of the water. The coarse filter layer 10, made of a large-pore metal mesh, can quickly intercept larger impurities in the water, such as sand and rust, reducing the burden on subsequent fine filtration. The fine filter layer 11, made of nanofiber filter material, can effectively filter out fine particles, suspended solids, and some bacteria due to its tiny pore size, significantly improving the purity of the water. The ion adsorption layer 12 can adsorb harmful substances such as heavy metal ions and residual chlorine in the water, improving the taste and quality of the water and meeting people's higher requirements for healthy water. It is especially suitable for direct drinking water systems or equipment with strict water quality requirements.

[0028] The filter housing 4 is made of transparent high-strength plastic material, which makes it easy to directly observe the pollution status of the filter element. Once the filter element is found to be darker in color and impurities are obviously accumulated, it can be cleaned or replaced in time to avoid affecting the filtration effect and water flow speed due to excessive clogging of the filter element. This can prevent water equipment from malfunctioning due to water quality problems in advance, and at the same time, it can reasonably arrange maintenance time, improve maintenance efficiency, and reduce maintenance costs.

[0029] The filter housing 4 has an annular flange 13 at the open end edge, and multiple evenly distributed anti-slip grooves are provided on the annular flange 13. This greatly facilitates the user's manual rotation, disassembly, and installation of the filter housing 4. No additional tools are needed; the user can easily rotate the filter housing 4 by making close contact with the anti-slip grooves with their fingers. Whether it is daily cleaning of the filter element or replacement after the filter element has reached the end of its service life, the operation becomes easy and efficient. Even users with less strength or poor hand dexterity can complete the task smoothly, improving the convenience of users maintaining the angle valve themselves.

[0030] The valve cover 6 is equipped with angle scale markings, allowing users to intuitively understand the opening and closing angle of the valve core. This enables precise control of the water flow. Users can adjust the valve core to the appropriate angle by observing the scale markings, depending on their actual water usage needs. For example, when washing clothes, a larger water flow is required. In scenarios such as watering plants, a smaller water flow can be precisely controlled to meet the different needs of water flow in different scenarios. This avoids the inconvenience caused by excessive or insufficient water flow, improving water usage efficiency and experience.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included within the protection scope of the present utility model.
