Abstract
Description
Technical Field
[0001] This utility model relates to the field of valve technology, specifically to a valve with anti-leakage function. Background Technology
[0002] A valve is a pipeline accessory used to control flow. It can open and close pipelines, control the direction of flow, and regulate and control the parameters (such as temperature, pressure, and flow rate) of the conveyed medium.
[0003] Existing valve bodies often cause users to have difficulty quickly determining the valve status and water flow, frequently leading to water waste or inconvenience due to misoperation. Insufficient sealing at the valve body-wall connection allows even minor leaks to seep into the wall or inside the tiles, causing tiles to become damp and fall off, and walls to mold, impacting the home environment. The valve core-base connection structure has poor stability; after prolonged operation or water flow impact, it is prone to loosening or even detachment, leading to leaks or malfunction. The traditional hexagonal disassembly structure of the valve core is located at the bottom, too close to the wall. During tiling, disassembling and reinstalling the valve core requires confined space, easily causing damage to the valve body or improper installation. During renovation, the opening between the valve body and the wall often results in gaps due to dimensional deviations, uneven wall surfaces, and other defects, affecting the overall aesthetics and lacking an effective covering structure. Utility Model Content
[0004] In view of the problems existing in the valves with the above-mentioned anti-leakage function, this utility model is proposed.
[0005] Therefore, the purpose of this utility model is to provide a valve with anti-leakage function, which solves the problems of unclear switch status, hidden danger of water seepage in the wall, easy loosening and falling off of valve core, difficulty in decoration and disassembly, and poor installation aesthetics.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A valve with anti-leakage function includes an anti-leakage valve body, an anti-detachment valve core base inside the anti-leakage valve body, a first valve core threaded on the top of the anti-detachment valve core base, an anti-leakage polygonal valve stem fixed on the top of the first valve core, a stainless steel decorative cover threaded on the stem wall of the anti-leakage polygonal valve stem, the stainless steel decorative cover engaging with the anti-leakage valve body, the anti-leakage valve body being made of stainless steel, a blue marking line and a red marking line fixed on the stem wall of the anti-leakage polygonal valve stem, a water inlet groove on the top of the anti-leakage valve body, and a polygonal extension rod fixed on the stem wall of the anti-leakage polygonal valve stem.
[0008] Preferably, one end of the anti-detachment valve core base is fixedly provided with anti-detachment teeth.
[0009] Preferably, the leak-proof polygonal valve stem is disc-shaped.
[0010] Preferably, there are three blue and three red marking lines.
[0011] Furthermore, the leak-proof valve body is T-shaped.
[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0013] This utility model uses blue (open) and red (closed) markings on the leak-proof polygonal valve stem to clearly indicate the switch status and degree of opening (each turn corresponds to 1 / 3 of the flow rate). Users can quickly identify and accurately adjust the valve, avoiding misoperation. The leak-proof valve body adopts a T-shaped flow guiding structure, which can guide any possible trace water seepage to the outside for discharge, preventing water from seeping into tiles or walls, protecting the integrity of the decoration, and extending the service life of walls and tiles. The serrated structure of the anti-detachment valve core base achieves bidirectional limiting. Clockwise adjustment is smooth and effortless, while counterclockwise operation is not easy to loosen or fall off due to the reverse resistance of the serrations, improving the stability of the valve core connection and its service life.
[0014] This utility model features a leak-proof polygonal valve stem with a hexagonal structure extending from the bottom to the top. During renovation, the valve core can be easily disassembled and installed through the top structure, without space limitations, avoiding damage to the valve body and improving renovation efficiency. The stainless steel decorative cover is connected to the valve body by a snap-fit, effectively covering up defects such as excessively large openings or uneven walls during renovation, enhancing the coordination between the valve and the home environment, and combining decoration and durability.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0023] This utility model discloses a valve with anti-leakage function.
[0024] This utility model provides, for example Figure 1-3The valve shown includes a leak-proof valve body 1, an anti-detachment valve core base 2 inside the leak-proof valve body 1, a first valve core 3 threaded onto the top of the anti-detachment valve core base 2, a leak-proof polygonal valve stem 4 fixedly mounted on the top of the first valve core 3, and a stainless steel decorative cover 5 threaded onto the wall of the leak-proof polygonal valve stem 4. The stainless steel decorative cover 5 is snap-fitted into the leak-proof valve body 1. The leak-proof valve body 1 is made of stainless steel. The wall of the leak-proof polygonal valve stem 4 is fixedly equipped with a blue marking line 6 and a red marking line 7. A water inlet groove 9 is opened on the top of the leak-proof valve body 1. A polygonal extension rod 10 is fixedly mounted on the wall of the leak-proof polygonal valve stem 4. The leak-proof valve body 1 is made of high-strength stainless steel, possessing corrosion resistance, high temperature resistance, and pressure resistance, and is suitable for environments with long-term contact with tap water. Structure: The valve features a T-shaped design with a dedicated internal flow channel for "water diversion and leak prevention." When a small amount of water leaks from the valve's connection to the pipe, the water is guided outwards along the flow channel, preventing it from seeping into the wall or tiles. This addresses the root cause of problems caused by leaks in traditional valves, such as mold growth and tile detachment. Installation compatibility: The valve body interface dimensions conform to general pipe standards and can be matched with common DN15 and DN20 water pipes, ensuring strong installation compatibility. Anti-detachment valve core base 2: Fixed inside the leak-proof valve body 1, it is the core support structure for the valve core. Anti-detachment design: One end of the base has ring-shaped anti-detachment teeth 8 with a unidirectional inclined angle, precisely engaging with the teeth at the bottom of the first valve core 3. When rotated clockwise: the anti-disengagement tooth 8 engages with the valve core teeth in a forward-facing manner, ensuring smooth tooth surface contact and low resistance, facilitating easy adjustment of the valve's open / closed state. When rotated counterclockwise: the anti-disengagement tooth 8 contacts the valve core teeth in a reverse-facing manner, with the tooth surface tilt angle creating mechanical resistance. This effectively prevents the valve core from loosening, retracting, or even falling off due to water flow impact, vibration, or misoperation, significantly improving the stability and service life of the valve core connection. The first valve core 3's function: through engagement with the anti-disengagement valve core base 2, it controls the flow of water and its volume. The valve core contains internal seals (such as rubber sealing rings) to ensure tightness in the closed state, reducing the risk of leakage. Connection method: the top is fixedly connected to the anti-leakage polygonal valve stem 4, and the bottom is threaded into the anti-disengagement valve core base 2 for secure installation. Furthermore, it boasts excellent sealing performance and a leak-proof polygonal valve stem with four structural features: The hexagonal disassembly structure of the valve stem extends from the bottom to the top of the valve core (in traditional valves, the hexagonal structure is usually only located at the bottom of the valve core, too close to the wall), solving the pain point of difficult valve core installation and removal during renovation. Practical advantages: During the tiling stage: The valve core can be easily removed by directly gripping the hexagonal structure at the top of the valve stem with a wrench, preventing the valve core from obstructing tile laying. After tiling: Utilizing the same top hexagonal structure, the valve core can be easily reinstalled without being limited by bottom space (such as insufficient gap between the wall and the valve body). The installation and removal process is effortless and will not damage the valve body or tiles. Operational convenience: The top of the valve stem has anti-slip textures, preventing slippage during manual rotation and improving the operating feel.Stainless Steel Decorative Cover 5 Material and Appearance: Made of 304 stainless steel with a polished surface, it has a smooth texture, is corrosion-resistant, and easy to clean. It matches the material of the leak-proof valve body 1, maintaining a unified overall style. Function: It is secured to the leak-proof valve body 1 via a snap-fit structure, fitting snugly at the connection between the valve body and the wall. It can conceal imperfections caused by oversized pipe openings, uneven walls, or gaps between the valve body and the wall during renovation, enhancing the overall aesthetics of the valve after installation and making the valve more harmonious with the wall decoration. Installation Flexibility: The inner diameter of the decorative cover can adapt to walls or tiles of different thicknesses. After installation, its position can be fine-tuned according to the actual gap to ensure effective coverage. Marking Lines (Blue Marking Line 66, Red Marking Line 77): These are printed on the stem wall of the leak-proof polygonal valve stem 4, arranged in a ring. Each group... The marking lines correspond to specific valve open / closed states. The number and meaning of the marking lines are as follows: There are three sets each of blue marking lines 6 and red marking lines 7. The color and the number of exposed rings visually indicate the valve's status and degree of openness: Blue marking line 6: Represents "Open". The more exposed rings, the greater the water flow—1 exposed ring corresponds to 1 / 3 flow rate, 2 exposed rings to 2 / 3 flow rate, and 3 fully exposed rings indicate a fully open valve. Red marking line 7: Represents "Closed". The more exposed rings, the tighter the closure—1 exposed ring corresponds to 1 / 3 closed, 2 exposed rings to 2 / 3 closed, and 3 fully exposed rings indicate a fully closed valve. Advantages: This solves the problem of "ambiguous open / closed status" caused by the lack of markings on traditional valves. Users can quickly determine the valve status without experience, avoiding misoperation (such as forgetting to close the valve). (Leakage or accidental closure affecting normal water use) All components are mechanically connected to form an organic whole: the anti-detachment valve core base 2 provides stable support for the valve core; the leak-proof polygonal valve stem 4 allows for convenient installation, removal, and operation; the leak-proof valve body 1 ensures leak-proof water intake; the marking lines provide visual status; and the stainless steel decorative cover 5 enhances aesthetics. These structures work together to ensure the valve's core function (water flow control) while specifically addressing the pain points of traditional valves, achieving multiple advantages of "leak prevention, stability, convenience, intuitiveness, and aesthetics." Before installation, check the product: After unpacking, confirm that the leak-proof valve body 1, anti-detachment valve core base 2, first valve core 3, leak-proof polygonal valve stem 4, stainless steel decorative cover 5, and other components are complete and free from damage or deformation. Confirm the installation location: Based on water usage requirements. Determine the valve installation location (e.g., under the kitchen sink, at the bathroom water heater interface, etc.), ensuring sufficient operating space around the valve body (it is recommended to reserve space with a diameter ≥10cm) for easy adjustment and maintenance later. Prepare the following tools: a wrench (compatible with the hexagonal size of the leak-proof polygonal valve stem 4), Teflon tape, screwdrivers, and sealant (optional, used to enhance the seal between the valve body and the wall). Installation process: Pipe pretreatment: Clean the water pipe interface to be connected, removing oil, rust, and other impurities, ensuring the interface is flat. Fixing the leak-proof valve body 1: Wrap an appropriate amount of Teflon tape around the water pipe interface (clockwise, 3-5 turns are sufficient; avoid excessive thickness which may prevent tightening). Align the inlet end of the leak-proof valve body 1 with the water pipe interface and tighten clockwise with a wrench.Ensure a tight connection (Note: Tighten with moderate force; excessive force may deform the valve body). Valve core and stem installation: If you are currently tiling, you can skip installing the first valve core 3 and only fix the leak-proof valve body 1. Proceed with the subsequent steps after the tiles are laid. After the tiles are laid, align the bottom of the first valve core 3 with the threaded interface of the anti-detachment valve core base 2. Use a wrench to hold the hexagonal structure at the top of the leak-proof polygonal valve stem 4 and rotate clockwise until the valve core and base are tightly engaged (Note: Initially, rotate slowly to ensure that the valve core teeth and anti-detachment teeth 8 are precisely aligned to avoid misalignment). Stainless steel decorative cover 5 installation: Slide the decorative cover onto the top of the valve stem and slide it down to the connection between the valve body and the wall. Gently press to engage and secure the decorative cover with the leak-proof valve body 1. Ensure the covering is tight and the position is correct. Water flow test: Open the upstream main valve and observe whether there is any leakage at the valve connection points. At the same time, rotate the valve stem to test the switch function. Confirm that the blue / red indicator line 7 is normal and there are no problems such as jamming or leakage. Switch operation: Open the valve: Rotate the leak-proof polygonal valve stem 4 clockwise. At this time, the blue indicator line 6 will gradually emerge from the inside of the valve body. Determine the degree of opening based on the number of turns that are exposed (1 turn = 1 / 3 flow, 2 turns = 2 / 3 flow, 3 turns = fully open). Stop rotating after reaching the required flow. Close the valve: Rotate the leak-proof polygonal valve stem 4 counterclockwise. The red indicator line 7 will gradually emerge. The more turns that are exposed, the tighter the closure. It is completely closed when 3 turns are fully exposed. Adjust the valve according to the water usage scenario (such as washing vegetables, washing hands, mopping). For applications such as floor cleaning, adjust the flow rate by observing the number of circles exposed on the blue indicator line 6: Low flow (e.g., handwashing): Adjust until the blue indicator line 6 is exposed once; Medium flow (e.g., washing vegetables): Adjust until the blue indicator line 6 is exposed twice; High flow (e.g., mopping, filling a basin): Adjust until the blue indicator line 6 is fully exposed three times. In daily use, the valve status can be quickly determined by the indicators on the valve stem without manual operation: If only the blue indicator line 6 is visible, the valve is open; the number of exposed circles corresponds to the degree of opening. If only the red indicator line 7 is visible, the valve is closed; the number of exposed circles corresponds to the tightness of closure. If both the blue and red indicator lines 7 are visible, the valve is partially open and can be further adjusted according to actual needs. Regular cleaning: Clean weekly with a dry cloth. Wipe the valve surface and stainless steel decorative cover 5 to remove dust and water stains, and avoid oil buildup affecting appearance and operation. If there are stubborn stains on the surface, wipe with a neutral detergent and then wipe clean with water. Do not use acidic or alkaline detergents (to avoid corroding the stainless steel material). Lubrication maintenance: Every six months, apply a small amount of food-grade lubricating oil (such as petroleum jelly) to the contact area between the leak-proof polygonal valve stem 4 and the valve body to reduce frictional resistance during rotation and keep operation smooth. Sealing check: Every three months, open the valve to its maximum position and observe whether there is water leakage at the connection between the valve core and the base. If water leakage is found, close the upstream main valve in time and check whether the valve core seal is aged (if aged, replace with the same model seal) or whether the valve core and the base are loose (tighten them again).Marker line maintenance: Avoid scratching the marker lines on the valve stem with hard objects. If the marker lines are worn and their visibility decreases, you can help determine the cause by recording the number of rotations (in the fully closed state, one clockwise rotation corresponds to opening 1 / 3 of the valve, and so on).
[0025] To prevent hair loss, such as Figure 2-3 As shown, anti-detachment teeth 8 are fixedly provided at one end of the anti-detachment valve core base 2.
[0026] And for ease of rotation, such as Figure 1 As shown, the leak-proof polygonal valve stem 4 is disc-shaped.
[0027] For ease of observation, such as Figure 1 As shown, there are 3 blue marking lines 6 and 3 red marking lines 7.
[0028] Finally, to facilitate traffic generation, such as Figure 1-3 As shown, the anti-leakage valve body 1 is T-shaped.
