Description

Technical Field

[0001] This utility model relates to the technical field of angle valves, and in particular to an angle valve with a filter structure. Background Technology

[0002] Angle valves are valves mainly used in daily life to control water flow. They are usually installed at the corners of water pipes, and their main function is to adjust the size and direction of water flow to meet different water needs. There are many types of angle valves, which can be divided into different types according to different uses and materials. Generally, they can be divided into cold water angle valves and hot water angle valves. According to materials, they can be divided into brass angle valves, stainless steel angle valves, plastic angle valves, etc. The structure of an angle valve is relatively simple, usually composed of a valve body, valve core, handle, and sealing gasket. The valve body is the main part of the angle valve, and its internal channel allows water to flow through. The valve core is the key part to control the water flow. It adjusts the size of the water flow by rotating or moving up and down. The sealing gasket is used to ensure the seal between the valve body and the valve core to prevent water leakage. Therefore, an angle valve with a filter structure is particularly needed.

[0003] However, existing angle valves are prone to water leakage during use, which wastes water resources and increases costs due to frequent maintenance. In addition, since ordinary angle valves do not have an internal filtration structure, they cannot guarantee the cleanliness of the water flow during use, thus affecting the user's access to clean water. Furthermore, the replacement of ordinary angle valves requires the removal and replacement of the entire valve, which increases maintenance costs. Utility Model Content

[0004] The purpose of this utility model is to provide an angle valve with a filter structure to solve the problems mentioned in the background art. In the process of use, because the angle valve has a valve core mechanism and a filter mechanism inside, ordinary angle valves are prone to water leakage, which wastes water resources and increases costs for frequent maintenance. At the same time, because ordinary angle valves do not have an internal filter structure, the cleanliness of the water flow cannot be guaranteed during use, thus affecting the user's access to clean water. Furthermore, ordinary angle valves require the removal and replacement of the entire angle valve when replaced, which increases maintenance costs.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-7 This utility model provides a technical solution: an angle valve with a filter structure, including an angle valve 1, a cap 2 fixedly connected to one end of the angle valve 1, a filter mechanism 3 provided on one side of the angle valve 1, and a valve core mechanism 4 provided at one end of the angle valve 1.

[0026] The filter mechanism 3 includes a side tube 301, a filter screen 302, and a first waterproof rubber ring 303. The side tube 301 is threadedly connected to one side of the angle valve 1. The filter screen 302 is fixedly connected to one side inside the side tube 301. The first waterproof rubber ring 303 is fixedly connected to one side of the side tube 301. During use, the filter mechanism 3 filters the water flow. The filter mechanism 3 can be disassembled or replaced by rotating it. The filter mechanism 3 can be replaced without replacing the angle valve 1, thereby saving costs.

[0027] Furthermore, the first waterproof rubber ring 303 is fixedly connected to one side of the angle valve 1, and the filter screen 302 is made of polyester. By fixing the first waterproof rubber ring 303 to one side of the angle valve 1, it can be ensured that there will be no water leakage at the connection between the first waterproof rubber ring 303 and the angle valve 1. The polyester material of the filter screen 302 makes the filter screen 302 more durable and more corrosion resistant, increasing the service life of the filter screen 302.

[0028] Furthermore, the valve core mechanism 4 includes a housing 401, a first engaging groove 402, an engaging strip 403, a fixing post 404, a waterproof groove 405, a second waterproof rubber ring 406, a connecting rod 407, a rotating base 408, a sliding groove 409, a sliding block 410, a rotating block 411, a second engaging groove 412, a threaded hole 413, a third waterproof rubber ring 414, a connecting strip 415, a first valve 416, a first valve port 417, a second valve 418, a second valve port 419, a first waterproof collar 420, and a second waterproof collar 421. The angle valve 1 is threadedly connected to the housing 401 on one side. The inner wall of the housing 401 has a first engaging groove 402, and the surface of the first engaging groove 402 is engaged with the engaging strip 403. One side of the engaging strip 403... A fixed post 404 is fixedly connected. One end of the fixed post 404 has a waterproof groove 405. A second waterproof rubber ring 406 is fixedly connected to the surface of the waterproof groove 405. A connecting rod 407 is fixedly connected to one end of the fixed post 404. A rotating base 408 is fixedly connected to the other end of the connecting rod 407. A sliding groove 409 is provided at one end of the rotating base 408. A sliding block 410 is slidably connected to the surface of the sliding groove 409. A rotating block 411 is fixedly connected to one end of the sliding block 410. A second engaging groove 412 is provided at one end of the rotating block 411. A threaded hole 413 is provided at one end of the rotating block 411. A third waterproof rubber ring 414 is fixedly connected to one end of the fixed post 404. A connecting strip 415 is fixedly connected to one end of the fixed post 404. The other end of 415 is fixedly connected to a first valve 416. Both ends of the first valve 416 have first valve ports 417. A second valve 418 is fixedly connected to one side of the inner side of the outer casing 401. Both ends of the second valve 418 have second valve ports 419. A first waterproof collar 420 is movably fitted onto one end of the outer casing 401, and a second waterproof collar 421 is fixedly connected to one side of the outer casing 401. During use, when it is necessary to install or disassemble the valve core mechanism of the angle valve 1, the screw connecting the cap 2 and the rotating block 411 can be loosened manually to remove the cap 2. Then, the outer casing 401 can be manually removed with pliers to extract the valve core mechanism 4. A new valve core mechanism 4 can then be installed. When it is necessary to adjust the water flow, the valve core mechanism 4 can be removed from the angle valve 1. By manually rotating the cap 2, the rotation of the cap 2 will drive the rotating block 411 to rotate. The rotation of the rotating block 411 will drive the sliding block 410 to rotate within the sliding groove 409. When the sliding block 410 abuts against one inner wall of the sliding groove 409, applying a torque in the same direction to the cap 2 will prevent the sliding block 410 from moving. Simultaneously, the rotating block 411 will drive the connecting strip 415 to rotate. The rotation of the connecting strip 415 will drive the first valve 416 to rotate. At this time, when the first valve port 417 rotates to communicate with the second valve 418, water will flow into the valve core mechanism 4. Then, the water will flow from the valve core mechanism 4 to the filter mechanism 3, achieving the effect of opening the angle valve 1. If the first valve port 417 rotates to close the second valve 418,Water will not enter valve core mechanism 4, thus achieving the effect of closing angle valve 1.

[0029] Furthermore, the sliding groove 409 and the sliding block 410 form a sliding structure, and the second engaging groove 412 engages with one end of the cap 2. By forming a sliding structure with the sliding groove 409 and the sliding block 410, the rotation of the rotating block 411 can be restricted, thereby making the rotation angle of the first valve 416 reasonable and allowing the first valve 416 to be adapted to the second valve 418. By setting the second engaging groove 412 to engage with one end of the cap 2, the rotational motion of the cap 2 can be better transmitted to the rotating block 411.

[0030] Furthermore, the cap 2 is fixedly connected to the threaded hole 413 by bolts, and the outer shell 401 is movably abutted against the second waterproof rubber ring 406. The fixed connection of the cap 2 to the threaded hole 413 by bolts makes the disassembly or installation of the cap simple and convenient, which helps to improve the efficiency of inspection or replacement. The movable abutment between the outer shell 401 and the second waterproof rubber ring 406 can ensure that water flow will not penetrate into the surface and interior of the rotating base 408, thereby ensuring that the rotation of the rotating base 408 will not be affected by water seepage and extending the service life of the valve core mechanism 4.

[0031] Furthermore, the first waterproof sleeve 420 is in movable contact with one side of the inside of the angle valve 1, and the second waterproof sleeve 421 is in movable contact with one side of the inside of the angle valve 1. Improving the movable contact between the first waterproof sleeve 420 and one side of the inside of the angle valve 1 ensures that water will not seep into the outer surface of one side of the valve core mechanism 4, thus extending the service life of the valve core mechanism 4. Improving the movable contact between the second waterproof sleeve 421 and one side of the inside of the angle valve 1 ensures that water will not seep out from the surface of one side of the valve core mechanism 4, thus increasing the service life of the valve core mechanism 4.

[0032] Furthermore, the second waterproof sleeve 421 is made of nitrile rubber (NBR), and the angle valve 1 is made of brass. The use of NBR for the second waterproof sleeve ensures its durability due to the special properties of the materials. The brass material for the angle valve 1 ensures a longer service life than ordinary alloys. Additionally, brass is less susceptible to corrosion from water flow compared to ordinary alloys, further increasing the service life of the angle valve 1 and reducing costs.

[0033] Furthermore, the first valve 416 is made of ceramic, and the connecting strip 415 is connected to the rotating base 408 by a bearing. With the ceramic material of the first valve 416, the ceramic material itself will not react chemically with water, and the ceramic material is not easily corroded by water, which increases the service life and reduces the cost. The connection between the connecting strip 415 and the rotating base 408 by a bearing can ensure that the connecting strip 415 can rotate smoothly in the rotating base 408 without being affected.

[0034] Furthermore, the connecting strip 415 and the rotating block 411 are fixedly connected, and the connecting rod 407 and the housing 401 are fixedly connected. The fixed connection between the connecting strip 415 and the rotating block 411 allows the rotational motion of the rotating block 411 to be better transmitted to the first valve 416. The fixed connection between the connecting rod 407 and the housing 401 ensures that the limiting effect of the sliding groove 409 on the sliding block 410 is better transmitted to the first valve 416, thereby ensuring a better cooperation between the first valve 416 and the second valve 418 and improving work efficiency.

[0035] Working Principle: During use, the filter mechanism 3 filters the water flow. It can be disassembled or replaced by rotating, allowing for replacement of the filter mechanism 3 without replacing the angle valve 1, thus saving costs. The fixed connection between the first waterproof rubber ring 303 and one side of the angle valve 1 ensures no leakage at the connection point. The polyester filter screen 302 is more durable and corrosion-resistant, increasing its service life. When installing or removing the valve core mechanism of the angle valve 1, first manually loosen the screw connecting the cap 2 and the rotating block 411, remove the cap 2, and then manually remove the outer casing 401 using pliers. The valve core mechanism 4 can then be removed from the angle valve 1, and a new valve core mechanism 4 can be installed to replace it. When it is necessary to adjust the water flow, the cap 2 can be manually rotated. The rotation of the cap 2 will drive the rotating block 411 to rotate, and the rotation of the rotating block 411 will drive the sliding block 410 to rotate in the sliding groove 409. When the sliding block 410 abuts against one side of the inner wall of the sliding groove 409, if a torque in the same direction is applied to the cap 2, the sliding block 410 will not move. At the same time, the rotating block 411 will drive the connecting strip 415 to rotate, and the rotation of the connecting strip 415 will drive the first valve 416 to rotate. At this time, when the first valve port 417 rotates to communicate with the second valve 418, the water flow will flow into the valve core mechanism 4, and then the water flow will exit from the valve core mechanism. 4. Water flows to the filter mechanism 3, achieving the effect of opening the angle valve 1. If the first valve port 417 rotates to the point where the second valve 418 is closed, the water flow will not enter the valve core mechanism 4, achieving the effect of closing the angle valve 1. The sliding structure formed by the sliding groove 409 and the sliding block 410 can limit the rotation of the rotating block 411, thereby making the rotation angle of the first valve 416 more reasonable and allowing the first valve 416 to adapt to the second valve 418. The setting of the second engaging groove 412 engaging with one end of the cap 2 allows the rotational movement of the cap 2 to be better transmitted to the rotating block 411. The setting of the cap 2 being fixedly connected to the threaded hole 413 by bolts makes the disassembly or installation of the cap simple and convenient, which is conducive to improving the efficiency of inspection or replacement. The movable contact between the high outer shell 401 and the second waterproof rubber ring 406 ensures that water flow will not penetrate the surface or interior of the rotating base 408, thus preventing water seepage from affecting the rotational movement of the rotating base 408 and extending the service life of the valve core mechanism 4. The use of nitrile rubber (NBR) for the second waterproof ring 421 ensures its durability due to the material's special properties. The brass angle valve 1 ensures a longer service life than ordinary alloys. Furthermore, brass is less susceptible to water corrosion than ordinary alloys, further increasing the lifespan of the angle valve 1 and reducing costs. The ceramic first valve 416...The inherent properties of ceramic material prevent it from chemically reacting with water, and its resistance to water corrosion increases its service life and reduces costs. The connection between the connecting strip 415 and the rotating base 408 via a bearing ensures smooth and unaffected rotation of the connecting strip 415 within the rotating base 408. The fixed connection between the connecting strip 415 and the rotating block 411 allows for better transmission of the rotating motion of the rotating block 411 to the first valve 416. The fixed connection between the connecting rod 407 and the outer casing 401 ensures that the limiting effect of the sliding groove 409 on the sliding block 410 is better transmitted to the first valve 416, thereby ensuring better cooperation between the first valve 416 and the second valve 418 and improving work efficiency.
