Description

Technical Field

[0001] This utility model belongs to the field of angle valve technology, and in particular relates to a water-stop angle valve. Background Technology

[0002] As a control component for the flow of water in pipelines, the stop valve is widely used in various places where fluid flow needs to be controlled, such as water pipe systems, steam pipelines, chemical, food, pharmaceutical, petroleum, power, and water treatment industries.

[0003] Traditional stop valves typically consist of a valve body and an inlet and an outlet end perpendicularly positioned on the side of the valve body. The valve is opened or closed by adjusting the valve core within the main body. A stop valve structure is usually installed at the outlet end to prevent water from entering after the water pipe is separated from the outlet. The snap-fit ​​connector used to install the stop valve structure is usually threaded or welded to the outlet end of the valve body. This means the snap-fit ​​connector is typically manufactured separately from the valve body, posing a risk of leakage and affecting reliability and sealing. Existing technologies have adopted designs that directly mold the snap-fit ​​connector onto the valve body, but these typically use easily machinable materials, such as plastic, to create an integrated snap-fit ​​connector and valve body structure. However, this results in poor structural strength and requires improvement. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned technical problems by providing a water-stop angle valve that achieves the effect of using metal materials to manufacture the snap-fit ​​connector and valve body in one piece, eliminating the risk of leakage and improving reliability and sealing.

[0005] In view of this, the present invention provides a water-stop angle valve, comprising:

[0006] The valve body contains a valve core.

[0007] The water inlet end is formed on the side of the valve body;

[0008] The water outlet is formed on the bottom surface of the valve body and has a snap-fit ​​connector integrally formed.

[0009] The valve body, inlet, outlet, and snap-fit ​​connectors are all made of metal.

[0010] Furthermore, the above technical solution also includes:

[0011] The water-stop core is installed inside the snap-fit ​​connector;

[0012] The snap-fit ​​connector is detachably connected to a water pipe with a quick connector, and includes a connecting part that connects to the water outlet and a slot for snapping the quick connector. The snap-fit ​​connector also has a chamber inside for installing a water-stop core.

[0013] In the above technical solution, further:

[0014] The valve body has an installation cavity, and the inner wall of the installation cavity has an inlet that communicates with the inlet end and an outlet that communicates with the outlet end.

[0015] The chamber, water outlet, and installation cavity are sequentially opened in the vertical direction.

[0016] In the above technical solution, the water-stopping core further includes:

[0017] The core is slidably installed in the chamber, and a blocking part is provided at one end near the valve core. The surfaces of the blocking part and the core form a water passage gap with the inner wall of the chamber.

[0018] The blocking part has an arc-shaped concave surface on the side closest to the valve core, and the radial cross-sectional area of ​​the blocking part is larger than the radial cross-sectional area of ​​the core.

[0019] In the above technical solution, further:

[0020] An annular protrusion is provided on the inner wall of the chamber at the end away from the valve core, and an annular groove is provided between the core and the blocking part, and a sealing ring is installed in the annular groove.

[0021] When the sealing ring mates with the annular protrusion, it can achieve a seal.

[0022] In the above technical solution, further:

[0023] The core body has a strip groove on its surface, and a radial water passage hole is formed on the inner wall of the strip groove on the side away from the valve core.

[0024] The end of the core away from the valve core has an axial water passage that communicates with the radial water passage.

[0025] In the above technical solution, further:

[0026] The core has multiple slots at one end of the axial water passage hole, forming multiple hook parts;

[0027] The hook and the blocking part are located on both sides of the annular protrusion.

[0028] In the above technical solution, further:

[0029] The valve body includes a main body and an end cap that is detachably connected to the inner wall of the mounting cavity, and one end of the valve core extends out of the end cap and is provided with a switch handle.

[0030] The beneficial effects of this utility model are as follows:

[0031] 1. By directly molding the snap-fit ​​connector to the outlet end of the valve body in one piece and using metal material, the structural strength of the stop valve can be guaranteed while effectively eliminating the risk of leakage and improving the reliability and sealing performance of the stop valve.

[0032] 2. By setting the snap-fit ​​connector as a connecting part and a slot part, the connection strength between the snap-fit ​​connector and the outlet end of the valve body is ensured, thereby ensuring the reliability of the connection between the stop valve and the water pipe with quick connector. In addition, the opening of the chamber facilitates the installation of the stop valve core and allows the outlet end to be closed in time if the water pipe with quick connector is accidentally dislodged, ensuring reliability.

[0033] 3. The water passage gap design allows the water outlet to be opened by the quick-connect fitting when the water pipe with the quick-connect fitting is installed on the snap-fit ​​fitting, ensuring water output efficiency. The arc-shaped concave surface on the blocking part can increase the impact force of the water flow on the blocking part. In the event of accidental detachment of the water pipe with the quick-connect fitting, the water outlet can be quickly stopped by pushing the water stop core. Attached Figure Description

Detailed Implementation

[0039] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0040] Example 1:

[0041] This embodiment provides a water-stop angle valve, including:

[0042] Valve body 1, with valve core 2 installed inside;

[0043] Water inlet end 3 is formed on the side of valve body 1;

[0044] The water outlet 4 is formed on the bottom surface of the valve body 1 and has a snap-fit ​​connector 5 integrally formed.

[0045] Among them, the valve body 1, the inlet end 3, the outlet end 4, and the snap-fit ​​connector 5 are all made of metal, and can be made of stainless steel.

[0046] Meanwhile, the integrated molding process of valve body 1, inlet end 3, outlet end 4, and snap-fit ​​connector 5 involves mixing stainless steel powder and plastic granules as a binder in a certain proportion, then mixing them in a mixer and injection molding them to form a fluid plastic material at high temperature. This material is then injected into a mold to form a green blank. The binder in the green blank is then removed by a high-temperature catalytic degreasing process. Finally, the degreased green blank is vacuum sintered to form a blank. Through the above process steps and with existing equipment, it is possible to achieve the integrated molding of snap-fit ​​connector 5 and valve body 1 made of metal. This can be achieved by those skilled in the art using existing equipment and the above process steps, and will not be elaborated further here.

[0047] As can be seen from this embodiment, by directly molding the snap-fit ​​connector 5 and the outlet end 4 of the valve body 1 into a single piece and using metal material, the structural strength of the water-stop angle valve can be guaranteed while effectively eliminating the risk of leakage and improving the reliability and sealing performance of the water-stop angle valve.

[0048] Furthermore, the valve body 1 part of the water-stop angle valve obtained by the above process has better surface finish and precision compared to parts formed by casting.

[0049] Example 2:

[0050] This embodiment provides a water-stop angle valve, which, in addition to the technical solutions of the above embodiments, also has the following technical features, and further includes:

[0051] Water-stopping core 6 is installed inside snap-fit ​​connector 5;

[0052] The snap-fit ​​connector 5 is detachably connected to a water pipe with a quick connector, and includes a connecting part 50 connected to the water outlet 4 and a slot part 51 for snapping the quick connector. The snap-fit ​​connector 5 has a chamber 52 inside for installing the water-stop core 6.

[0053] Meanwhile, the specific structure of the quick connector is a mature existing technology, and the specific shape of the slot 51 is adapted to the quick connector, which is also a mature existing technology, and will not be elaborated here.

[0054] As can be seen from this embodiment, by setting the snap-fit ​​connector 5 as a connecting part 50 and a slot part 51, the connection strength between the snap-fit ​​connector 5 and the water outlet 4 of the valve body 1 is ensured, thereby ensuring the reliability of the connection between the water stop angle valve and the water pipe with quick connector. Furthermore, the opening of the chamber 52 facilitates the installation of the water stop core 6, and facilitates the timely closure of the water outlet 4 after the water pipe with quick connector accidentally falls off, thus ensuring reliability.

[0055] Example 3:

[0056] This embodiment provides a water-stop angle valve, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0057] The valve body 1 has an installation cavity 10, and the inner wall of the installation cavity 10 has an inlet 11 that communicates with the inlet end 3 and an outlet 12 that communicates with the outlet end 4.

[0058] The chamber 52, the outlet 12, and the installation chamber 10 are sequentially opened in the vertical direction.

[0059] As can be seen from this embodiment, the installation cavity 10 facilitates the installation of the valve core 2. The chamber 52, the outlet 12, and the installation cavity 10 are opened in sequence along the vertical direction, which facilitates the sequential installation of the water-stopping core 6 and the valve core 2, and improves the ease of assembly.

[0060] Example 4:

[0061] This embodiment provides a water-stop angle valve, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the water-stop core 6 includes:

[0062] The core 60 is slidably installed in the chamber 52, and a blocking part 61 is provided at one end near the valve core 2. The surfaces of the blocking part 61 and the core 60 form a water passage gap 62 with the inner wall of the chamber 52.

[0063] Among them, the blocking part 61 has an arc-shaped concave surface 63 on the side near the valve core 2, and the radial cross-sectional area of ​​the blocking part 61 is larger than the radial cross-sectional area of ​​the core 60.

[0064] As can be seen from this embodiment, the water passage gap 62 facilitates the opening of the water outlet 4 by pushing the water stop core 6 from inside the quick connector when the water pipe with quick connector is installed on the snap connector 5, thus ensuring water output efficiency. The arc-shaped concave surface 63 on the blocking part 61 can increase the impact force of the water flow on the blocking part 61. In the event of accidental detachment of the water pipe with quick connector, the water stop core 6 can be quickly pushed to stop the water flow at the water outlet 4.

[0065] Example 5:

[0066] This embodiment provides a water-stop angle valve, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0067] An annular protrusion 53 is provided on the inner wall of the end of the chamber 52 away from the valve core 2, and an annular groove 64 is provided between the core 60 and the blocking part 61, and a sealing ring 7 is installed in the annular groove 64.

[0068] Among them, the sealing ring 7 can be sealed when it is engaged with the annular protrusion 53;

[0069] Meanwhile, the sealing ring 7 can be made of rubber.

[0070] As can be seen from this embodiment, by forming an annular protrusion 53 on the inner wall of the chamber 52 in the snap-fit ​​connector 5, and with the cooperation of the other sealing rings 7, it is possible to achieve water flow pushing the water-stopping core 6 to seal the sealing rings 7 and the annular protrusion 53 after the water pipe with the quick connector accidentally leaks, thus effectively stopping the water flow, preventing the waste of a large amount of water resources when no one is around, and ensuring the reliability of the water-stopping angle valve.

[0071] Example 6:

[0072] This embodiment provides a water-stop angle valve, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0073] The core 60 has a strip groove 65 on its surface, and a radial water passage hole 66 is provided on the inner wall of the strip groove 65 on the side away from the valve core 2.

[0074] Among them, the end of the core 60 away from the valve core 2 is provided with an axial water passage 67 that communicates with the radial water passage 66;

[0075] Meanwhile, the surface of the annular protrusion 53 is slidably connected to the surface of the core 60.

[0076] As can be seen from this embodiment, by setting the strip groove 65, the radial water passage hole 66, and the axial water passage hole 67, the water passage area of ​​the water passage gap 62 entering the radial water passage hole 66 can be increased, thereby effectively ensuring the water passage efficiency of the water stop angle valve.

[0077] Furthermore, the surface of the annular protrusion 53 is slidably connected to the surface of the core 60, which can effectively improve the stability of the water-stopping core 6 when it moves.

[0078] Example 7:

[0079] This embodiment provides a water-stop angle valve, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0080] The core 60 has multiple slots 68 at one end of the axial water passage 67, and forms multiple hook parts 69;

[0081] The hook portion 69 and the blocking portion 61 are located on both sides of the annular protrusion 53, respectively.

[0082] Meanwhile, four slots 68 can be used, with equal spacing around the circumference.

[0083] As can be seen from this embodiment, the multiple slots 68 opened at one end of the core 60 enable the core 60 to form a hook portion 69. After the core 60 is installed, both ends of the core 60 can be restricted to the two sides of the annular protrusion 53, preventing the water-stop core 6 from falling off the snap-fit ​​connector 5 and improving the installation stability of the water-stop core 6. Furthermore, the design of the hook portion 69 allows the water-stop core 6 to be pressed down during installation so that the hook portion 69 passes through the annular protrusion 53, making assembly quick and convenient.

[0084] Example 8:

[0085] This embodiment provides a water-stop angle valve, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0086] The valve body 1 includes a main body and an end cap 13 that is detachably connected to the inner wall of the mounting cavity 10, and the valve core 2 extends out of the end cap 13 and is provided with a switch handle 14.

[0087] The detachable connection between the main body and the end cap 13 can be a threaded connection.

[0088] As can be seen from this embodiment, by using an end cap 13 that is detachably connected to the inner wall of the mounting cavity 10, the stability of the valve core 2 installation is improved, and the switch handle 14 can facilitate the adjustment of the valve core 2, thus improving the ease of use.

[0089] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
