Description

Technical Field

[0001] This utility model relates to the field of angle valve technology, and specifically to an angle valve. Background Technology

[0002] Currently, with the increasing variety of water-using sanitary ware products, the requirements for water quality are also becoming more stringent in order to enhance the enjoyment and user experience of daily life. For example, in some areas, the water contains a lot of impurities such as sediment and rust, which can cause blockages or blockages in water-using sanitary ware, leading to poor water flow or even leaks. In other areas, the water contains high levels of calcium and magnesium ions, which can form limescale over time, affecting the normal function and aesthetic experience of sanitary ware.

[0003] Chinese utility model patent CN 201502715U discloses a filter angle valve, including a cylindrical valve body with an outlet on the side and an inlet at the bottom. An axially movable valve stem is located within the valve body. A valve plate on the valve stem, when moved upwards, blocks the communication channel between the inlet and outlet. A spring is fitted onto the valve stem, pressing against the valve body to lift the stem. An axially movable switch cap, sealing the valve body, is located at the upper opening of the valve body. The upper end of the valve stem rests below the switch cap. A cylindrical filter screen, covering the space between the inlet and outlet, is located below the switch cap. Twisting the switch cap moves the valve stem downwards or upwards, causing the valve plate to disengage from or block the communication channel between the inlet and outlet, thereby controlling water flow or shut-off.

[0004] This angle valve has a valve plate fixedly mounted on the valve stem, with the upper end of the stem resting under the switch cap and the lower end passing through the screw nut. However, due to the long length of the valve stem and the lack of a fixed connection between the upper end of the stem and the switch cap, the valve stem swings left and right as the switch cap is turned, making it prone to breakage. Once the valve stem breaks, the valve plate must be replaced simultaneously, increasing maintenance costs. Therefore, we provide an angle valve to address this issue. Utility Model Content

[0005] In order to overcome the above-mentioned shortcomings in the existing technology, the purpose of this utility model is to provide an angle valve that is safe to use and not easily damaged.

[0006] This utility model is achieved through the following technical solution: An angle valve includes a valve body, an inlet port, an outlet port, and a filter chamber formed on the valve body. The filter chamber is connected to both the inlet port and the outlet port. The valve body has an axially movable valve stem. The valve stem has a sealing part that can block the communication channel between the inlet port and the outlet port when it moves upward. The upper opening of the valve body has an axially movable switch knob that seals with the valve body. The filter chamber has a filter screen cylinder fixed by the switch knob. The switch knob has a positioning groove that cooperates with the valve stem for positioning. The valve body has a valve assembly hole for the valve stem to pass through. The assembly hole is located at the junction of the inlet port and the filter chamber. The valve stem has two non-rigid limiting parts located in the filter chamber. The non-rigid limiting parts are symmetrically distributed on the left and right sides of the valve stem. The distance between the two non-rigid limiting parts is greater than the diameter of the assembly hole.

[0007] As a further improvement of the angle valve of this utility model, the switch knob includes a connecting section, a sealing section, a threaded section and a support section integrally formed from top to bottom, and the filter screen cylinder is fixed in the support section.

[0008] As a further improvement to the angle valve of this utility model, a sealing device is provided between the sealing section and the valve body.

[0009] As a further improvement of the angle valve of this utility model, the sealing device is a sealing ring, and the sealing section is provided with a first sealing groove along the circumference for the sealing ring to be embedded in. The sealing ring is embedded in the first sealing groove.

[0010] As a further improvement to the angle valve of this utility model, the bottom of the valve stem is also provided with a pressure-bearing part integrally formed therewith, and the outer diameter of the pressure-bearing part is larger than the diameter of the assembly hole.

[0011] As a further improvement to the angle valve of this utility model, the pressure-bearing part is provided with a second sealing groove for fixing the sealing part.

[0012] As a further improvement to the angle valve of this utility model, the upper opening of the valve body is provided with an internal thread for assembly with the threaded section of the switch knob, and the switch knob can be screwed onto the internal thread of the opening along the axial direction.

[0013] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0014] 1. This utility model has a positioning groove at the lower end of the switch knob for fixing the valve stem, so that the valve stem remains fixed in the positioning groove when it moves upward. This can prevent the valve stem from swinging left and right as the switch cap is turned due to its excessive length, which could easily lead to breakage. This reduces the cost of use and increases the service life of the product.

[0015] 2. This utility model has limiting parts on both sides of the valve stem, so that the angle valve can be installed in the vertical or horizontal pipeline, thus not being restricted by the direction of the pipeline.

In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] like Figures 1 to 3 As shown, an angle valve includes a valve body 1, an inlet port 10, an outlet port 11, and a filter chamber 12 formed on the valve body 1. The filter chamber 12 is connected to both the inlet port 10 and the outlet port 11. The valve body 1 has an axially movable valve stem 2. The valve stem 2 has a sealing part 3 that can block the communication channel between the inlet port 10 and the outlet port 11 when it moves upward. The upper opening 13 of the valve body has an axially movable switch knob 4 that seals with the valve body 1. The filter chamber 12 has a filter screen cylinder 5 fixed by the switch knob 4. The switch knob 4 has a positioning groove 6 that cooperates with the valve stem 2 for positioning. The valve body 1 is equipped with a valve stem 2 through which the filter stem 2 passes. The valve stem 2 has a non-rigid limiting part 20 located in the filter chamber 12. The non-rigid limiting part 20 is provided on the valve stem 2 and is symmetrically distributed on the left and right sides of the valve stem 2. The distance between the two non-rigid limiting parts 20 is greater than the diameter of the mounting hole 14. Since the limiting part is made of non-rigid material, it has a certain toughness. During installation, the valve stem enters the filter chamber through the inlet water inlet. When the non-rigid limiting part 20 passes through the mounting hole 14, it is squeezed by the inner wall of the mounting hole, causing the non-rigid limiting part 20 to deform outward of the valve stem and pass through the mounting hole, so that the valve stem can be fixed in the valve body.

[0032] When the valve stem 2 moves downward or upward, the sealing part 3 leaves or blocks the assembly hole 14 to control the angle valve to discharge or close.

[0033] As a further improvement, the switch knob 4 also includes a connecting section 40, a sealing section 41, a threaded section 42 and a support section 43 integrally formed from top to bottom. The filter screen cylinder 5 is fixed inside the support section 43. Specifically, the upper end of the filter screen cylinder 5 is connected to the inside of the switch knob 4. When the filter screen cylinder needs to be cleaned, the switch knob can be turned off directly to remove the filter screen cylinder for rinsing.

[0034] As a further improvement, in order to improve the water tightness between the switch knob and the valve body, a sealing device 7 is provided between the sealing section 41 and the valve body 1. The sealing device 7 is a sealing ring. The sealing section 41 is provided with a first sealing groove 410 along the circumference for the sealing ring to be embedded in. The sealing ring is embedded in the first sealing groove 410.

[0035] As a further improvement, the bottom of the valve stem 2 is also provided with a pressure-bearing part 21 integrally formed therewith. The outer diameter of the pressure-bearing part 21 is larger than the diameter of the assembly hole 14. The pressure-bearing part 21 is provided with a second sealing groove 210 for fixing the sealing part 3. When the switch knob is removed, the valve stem will move upward under the action of water pressure, so that the sealing part blocks the assembly hole 14. At the same time, the pressure-bearing part 21 abuts against the outer edge of the assembly hole 14, so that the water in the pipeline will not leak into the assembly hole 14, ensuring good water tightness between the sealing part and the assembly hole 14.

[0036] As a further improvement, the upper opening 13 of the valve body is provided with an internal thread 15 that is fitted to the threaded section 42 of the switch knob 4. The switch knob 4 can be screwed onto the internal thread 15 of the opening along the axial direction, thereby facilitating the disassembly and assembly of the switch knob.

[0037] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
