Description

Technical Field

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

[0002] Angle valves are common switching devices used in daily life to connect to water supply networks. These networks often contain solid debris such as scale and sediment. The inventors have developed a new angle valve structure in which a sliding valve tube is inserted within the inlet pipe. A water-stop ring is installed at the bottom of the valve tube, allowing for both closing and opening of the inlet through axial movement.

[0003] During the test, it was found that if mud and sand enter the gap between the water valve pipe and the water inlet pipe, it can easily affect the smooth sliding of the water valve pipe relative to the water inlet pipe of the angle valve housing.

[0004] In view of this, the inventor conducted in-depth research on the aforementioned deficiencies in the prior art, which led to the creation of this case. Utility Model Content

[0005] The main purpose of this utility model is to provide an angle valve water inlet structure and an improved angle valve.

[0006] To achieve the above objectives, the solution of this utility model is:

[0007] An angle valve inlet structure includes an angle valve housing and a water passage valve pipe. The angle valve housing has an inlet pipe, and the water passage valve pipe passes through the inlet pipe and is slidably connected to the inner cavity of the inlet pipe. A water-stop ring for opening or closing the opening of the inlet pipe is provided at the lower part of the water passage valve pipe. A side water passage is formed on the side wall of the water passage valve pipe above the water-stop ring. The water passage valve pipe has a sliding section located above the side water passage. A water passage center cavity is formed axially in the sliding section, and the lower part of the water passage center cavity communicates with the side water passage. A blocking rubber ring is provided on the outer wall of the sliding section near the side water passage. The blocking rubber ring remains in contact with the inner wall of the inlet pipe during the sliding process of the water passage valve pipe.

[0008] Furthermore, the blocking rubber ring is an O-ring seal.

[0009] Furthermore, the sliding section is provided with a mounting groove for installing the blocking rubber ring, and the distance between the lower edge of the mounting groove and the upper edge of the side water outlet is less than or equal to 1 mm.

[0010] Furthermore, the lower edge of the blocking rubber ring is flush with the upper edge of the side water inlet.

[0011] Furthermore, the rotating cross-section of the blocking rubber ring is T-shaped or L-shaped.

[0012] Furthermore, the water-passing valve pipe has an upper limit position and a lower limit position relative to the water inlet pipe; when the water-passing valve pipe is in the upper limit position, the water-stop ring blocks the opening of the water inlet pipe; when the water-passing valve pipe is in the lower limit position, the lower edge of the blocking rubber ring is still higher than the opening of the water inlet pipe.

[0013] Furthermore, the opening of the water inlet pipe is formed with a conical guide portion, and the water stop ring has an upper conical surface; the upper conical surface and the conical guide portion contact each other when the water inlet pipe is blocked; when water is flowing, a guiding space is formed between the upper conical surface and the conical guide portion to guide the water flow to the side outlet.

[0014] Furthermore, the side water inlets are arranged in annular intervals on the side of the water valve pipe, and axially arranged connecting ribs are provided between adjacent side water inlets.

[0015] An improved angle valve includes the aforementioned angle valve inlet structure and a hand-tightening control unit. The upper part of the angle valve housing has a mounting cavity with an internal thread. The hand-tightening control unit has a handle and a contact portion. The side wall of the contact portion has an external thread, and the contact portion is connected to the internal thread of the mounting cavity via the external thread. A handle is provided on the upper part of the contact portion. The lower part of the contact portion abuts against the upper part of the water-passing valve pipe, and a spring is fitted over the water-passing valve pipe to push it towards the contact portion.

[0016] Furthermore, a receiving cavity is formed at the top of the abutting part, and a counterweight is disposed in the receiving cavity; the handle is fastened to the outside of the abutting part and covers the receiving cavity; a locking tooth structure is provided between the handle and the upper part of the abutting part.

[0017] With the above structure, the angle valve inlet structure and improved angle valve of this utility model have at least the following beneficial effects:

[0018] 1. The blocking rubber ring blocks the gap between the sliding section above the side water inlet and the water inlet pipe, preventing impurities such as mud and scale from entering and affecting the smooth sliding of the water valve pipe.

[0019] 2. The blocking rubber ring is fixedly connected to the outer wall of the water inlet valve pipe through the mounting groove, and the blocking rubber ring slides against the inner wall of the water inlet pipe as the water inlet valve pipe moves.

[0020] Third, by minimizing the gap between the lower edge of the blocking rubber ring and the upper edge of the side water outlet, the space for sediment retention is reduced, thus reducing the impact of sediment on the smoothness of the water valve pipe.

[0021] Fourth, the guiding space formed by the conical guide and the upper conical surface allows water to flow more smoothly through the side water outlet, reducing the amount of sediment remaining in the side water outlet.

[0022] 5. The hand-tightening control unit rotates to move axially relative to the angle valve housing, thereby adjusting the axial position of the water valve pipe and regulating water flow. A counterweight is installed inside the hand-tightening control unit, and the handle engages with the control unit to prevent water droplets from entering the receiving cavity and corroding the counterweight.

[0023] Compared with the prior art, this utility model provides a blocking rubber ring on the outer wall of the sliding section near the side water outlet, which blocks the gap between the sliding section and the inner wall of the water inlet pipe, thus preventing mud and sand from entering and affecting the smooth sliding of the water valve pipe.

Detailed Implementation

[0037] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0038] like Figures 1 to 3 and Figure 10 As shown, this utility model relates to a water inlet structure for an angle valve, comprising an angle valve housing 1 and a water inlet valve pipe 2. The angle valve housing 1 has a water inlet pipe 11, and the water inlet valve pipe 2 passes through the water inlet pipe 11 and is slidably connected to the inner cavity of the water inlet pipe 11. A water stop ring 21 for opening or closing the opening of the water inlet pipe 11 is provided at the lower part of the water inlet valve pipe 2. A side water outlet 22 is formed on the side wall of the water inlet valve pipe 2 above the water stop ring 21. The water inlet valve pipe 2 has a sliding section 24 located above the side water outlet 22. A water inlet center cavity 23 is formed axially in the sliding section 24, and the lower part of the water inlet center cavity 23 is connected to the side water outlet 22. A blocking rubber ring 25 is provided on the outer wall of the sliding section 24 near the side water outlet 22. The blocking rubber ring 25 remains in contact with the inner wall of the water inlet pipe 11 during the sliding process of the water inlet valve pipe 2.

[0039] Thus, the angle valve inlet structure and improved angle valve of this utility model block the gap between the sliding section 24 above the side water outlet 22 and the water inlet pipe 11 by the blocking rubber ring 25, so as to prevent impurities such as mud and scale from entering and affecting the smooth sliding of the water valve pipe 2.

[0040] Preferably, such as Figures 1 to 3 As shown, the blocking rubber ring 25 is an O-ring seal.

[0041] Preferably, the sliding section 24 is provided with a mounting groove 241 for installing the blocking rubber ring 25, and the distance between the lower edge of the mounting groove 241 and the upper edge of the side water outlet 22 is less than or equal to 1 mm. The blocking rubber ring 25 is fixedly connected to the outer wall of the water valve pipe 2 through the mounting groove 241, and the blocking rubber ring 25 slides against the inner wall of the water inlet pipe 11 as the water valve pipe 2 moves. The lower edge of the mounting groove 241 is as close as possible to the upper edge of the side water outlet 22 so that the blocking rubber ring 25 is as close as possible to the side water outlet 22; the mounting groove 241 can be used to install O-ring seals, or it can be used to rotate blocking rubber rings 25 with a T-shaped or L-shaped cross section (such as...). Figure 11 The rotating section shown is a T-shaped blocking rubber ring 25.

[0042] like Figure 8 As shown, the lower edge of the blocking rubber ring 25 is flush with the upper edge of the side water outlet 22. This completely blocks the gap between the sliding section 24 of the side water outlet 22 and the inlet pipe 11. By minimizing the gap between the lower edge of the blocking rubber ring 25 and the upper edge of the side water outlet 22, the space for sediment accumulation is reduced, thus minimizing the impact of sediment on the smoothness of the water flow valve pipe 2.

[0043] Preferably, the water-passing valve pipe 2 has an upper limit position and a lower limit position relative to the water inlet pipe 11; when the water-passing valve pipe 2 is in the upper limit position, the water-stop ring 21 seals the opening of the water inlet pipe 11, such as... Figure 2 As shown.

[0044] When the water valve pipe 2 is in the lower limit position, it is in a water-flow state, and the lower edge of the blocking rubber ring 25 is still higher than the opening of the water inlet pipe 11. Figure 1 As shown, this prevents the rubber ring 25 from being firmly confined between the water valve pipe 2 and the inner wall of the water inlet pipe 11, making it less likely to fall off and fail.

[0045] Preferably, the opening of the water inlet pipe 11 is formed with a conical guide portion 111, and the water-stop ring 21 has an upper conical surface 211; the upper conical surface 211 and the conical guide portion 111 contact each other when the water inlet pipe 11 is blocked; when water is flowing, a guiding space is formed between the upper conical surface 211 and the conical guide portion 111 to guide the water flow to the side water outlet 22. The guiding space formed by the conical guide portion 111 and the upper conical surface 211 allows the water flow to pass through the side water outlet 22 more smoothly, reducing the amount of sediment remaining in the side water outlet.

[0046] Preferably, the side water inlets 22 are arranged in a ring at intervals on the side of the water valve pipe 2, and axially arranged connecting ribs 221 are provided between adjacent side water inlets 22. By circumferentially arranging multiple side water inlets 22, water can be passed through in all directions and sediment can be avoided, ensuring the water flow rate.

[0047] This utility model also provides an improved triangular valve, such as Figures 4 to 9 As shown, the device includes the aforementioned angle valve inlet structure and a manual control unit 3. The upper part of the angle valve housing 1 has a mounting cavity 12, and the mounting cavity 12 has an internal thread 121. The manual control unit 3 has a handle 31 and an abutment part 32. The side wall of the abutment part 32 has an external thread 321, and the abutment part 32 is connected to the internal thread 121 of the mounting cavity 12 via the external thread 321. The upper part of the abutment part 32 has a handle 31. The lower part of the abutment part 32 abuts against the upper part of the water passage valve pipe 2, and a spring 4 is fitted around the water passage valve pipe 2 to push it towards the abutment part 32. The manual control unit 3 rotates to achieve axial movement relative to the angle valve housing 1, thereby adjusting the axial position of the water passage valve pipe 2 and regulating water flow.

[0048] A filter screen 322 can also be installed on the abutment part 32 below the external thread 321. Water flows through the filter screen 322 and then flows out from the water outlet pipe 13 on the side of the angle valve housing 1 to collect solid debris such as scale.

[0049] Preferably, the top of the abutment portion 32 is formed with a receiving cavity 323, such as... Figure 8 and Figure 9 As shown, a counterweight 324 is provided inside the receiving cavity 323; the handle 31 is fastened to the outside of the abutment portion 32 and covers the receiving cavity 323; a locking tooth engagement structure is provided above the handle 31 and the abutment portion 32. The counterweight 324 is provided inside the hand-tightening control part 3, and the handle 31 is fastened to the hand-tightening control part 3 to prevent water droplets from entering the receiving cavity 323 and corroding the counterweight 324. The locking tooth engagement structure includes several locking blocks 311 located on the handle 31 and several locking slots 325 located at the top of the receiving cavity 323, and the locking blocks 311 can be locked into the locking slots 325.

[0050] Compared with the prior art, the present invention provides a blocking rubber ring 25 on the outer wall of the sliding section 24 near the side water outlet 22, which blocks the gap between the sliding section 24 and the inner wall of the water inlet pipe 11, thus preventing mud and sand from entering and affecting the smooth sliding of the water valve pipe 2.

[0051] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
