Description

Technical Field

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

[0002] An angle valve is a type of valve similar to a ball valve. The inlet and outlet channels of an angle valve are set at a 90-degree angle, and it is used for water outlet connections in special locations, such as connecting washing machine pipes, toilet pipes, and shower pipes.

[0003] Most existing angle valves use a valve core structure, utilizing the interaction of fixed and moving ceramic discs to open and close the water flow. However, this structure may have the following problems:

[0004] First, by setting through holes on the moving ceramic plate for water to flow through, the through holes are small, resulting in a small water flow, especially when the water pressure is low, which affects the use.

[0005] Secondly, the valve core structure not only requires a more complicated assembly process, but also results in a higher overall cost.

[0006] Therefore, the inventors specifically designed an angle valve structure, which led to this invention. Utility Model Content

[0007] This utility model addresses the technical problem by providing an angle valve structure that overcomes at least one of its defects; the technical solution adopted is:

[0008] An angle valve structure includes an outer shell, a ball head disposed inside the outer shell for cutting off water flow, and a valve stem for driving the ball head to rotate and rotatably connected to the outer shell;

[0009] The outer casing has an internal cavity for mounting a ball head. A water inlet channel communicating with the cavity is provided on the lower part or side wall of the outer casing. An installation channel communicating with the cavity is provided above the inlet channel for mounting a valve stem. A first limiting step is provided on the inner side wall of the installation channel near the opening to restrict the rotation of the valve stem. A second limiting step is provided on the valve stem.

[0010] Furthermore, the angle valve structure also includes a connector connected to the outer casing. The connector is hollow inside and has a water outlet channel. The central axis of the water inlet channel is perpendicular to the central axis of the water outlet channel.

[0011] Furthermore, the ball head has a water passage at a 90-degree angle that connects the inlet and outlet water passages. The receiving cavity has sealing gaskets located on both sides of the ball head, and the inner side of the sealing gaskets is fitted to the ball head.

[0012] Furthermore, the ball head has a T-shaped water passage inside. By setting the T-shaped water passage, the ball head can be installed arbitrarily, as long as the second connecting section is embedded in the slot.

[0013] Furthermore, when the angle valve structure is open, the water passage connects the inlet channel and the outlet channel; when the angle valve structure is closed, the ball head blocks the connection between the inlet channel and the outlet channel; a first clearance hole is provided in the middle of the sealing gasket near the joint.

[0014] Furthermore, the valve stem is rotated relative to the outer casing via a knob.

[0015] Furthermore, a first external thread is provided on the outer shell and on the outer wall of the water inlet channel, the first external thread being close to the opening of the water inlet channel.

[0016] Furthermore, a limiting groove is formed between the two first limiting steps, and the second limiting step rotates within the groove to limit the rotation angle of the valve stem.

[0017] Furthermore, the valve stem sequentially includes a first connecting section, a rotating section, a sealing section, and a second connecting section. The rotating section and the sealing section are located within the installation channel, and the second limiting step is disposed on the outer wall of the rotating section.

[0018] Furthermore, at least one first sealing ring is fitted onto the outer wall of the sealing section, and the first sealing ring is located between the sealing section and the installation channel.

[0019] Furthermore, at least one annular groove is provided on the outer wall of the sealing section, and the first sealing ring is fitted inside the annular groove.

[0020] The first connecting section is located on the outside of the outer casing and is used to connect the knob.

[0021] Furthermore, the rotating section includes a rotating part and a limiting part located within the installation channel, the limiting part being located below the first limiting step and the second limiting step being located outside the rotating part.

[0022] Furthermore, a slot for embedding the second connecting segment is provided above the ball head.

[0023] Furthermore, the first connecting segment adopts a quadrilateral structure, and the knob is provided with a connecting groove for matching the quadrilateral structure.

[0024] Furthermore, the outer wall of the connector is threadedly connected to the outer casing.

[0025] Furthermore, a second sealing ring is provided between the connector and the outer casing.

[0026] The angle valve structure of this utility model greatly improves the flow rate by replacing the existing valve core with a ball head and using the valve stem to drive the ball head to rotate. At the same time, the overall structure is simple and does not require complicated assembly, which not only improves assembly efficiency but also reduces costs. Furthermore, the first limiting step of this utility model is set at the opening of the installation channel, which is easy to process. The first limiting step can not only limit the rotation angle of the valve stem but also restrict the valve stem to the outer shell. Attached Figure Description

Detailed Implementation

[0044] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of this application. Example 1

[0045] Please see Figures 1 to 11This invention provides an angle valve structure as an embodiment 1, comprising a housing 100, a ball head 200 disposed inside the housing 100 for cutting off water flow, a valve stem 300 for rotating the ball head 200 and rotatably connected to the housing 100, and a connector 400 connected to the housing 100; the housing 100 has a receiving cavity 110 for mounting the ball head 200 inside, an inlet channel 120 communicating with the receiving cavity 110 is provided below or on the side wall of the housing 100, and an installation channel 130 for mounting the valve stem 300 and communicating with the receiving cavity 110 is provided above it; the connector 400 is hollow inside and has an outlet channel 410, with the central axis of the inlet channel 120 and the central axis of the outlet channel 410 being perpendicularly aligned. In this invention, the central axes of the inlet channel 120 and the installation channel 130 are on the same straight line, allowing the valve stem 300 to pass through the inlet channel 120 and be installed into the installation channel 130. The outer shell 100 and connector 400 of this utility model facilitate the overall installation of the angle valve structure, and both can be made of metal, such as stainless steel, which can improve the service life of the angle valve structure. The sealing gasket 500 is made of Teflon or silicone.

[0046] Please see Figure 3 The ball head 200 has a 90-degree water passage 210 inside, which connects the inlet channel 120 and the outlet channel 410. Sealing gaskets 500 are located inside the receiving cavity 110 on both sides of the ball head 200, with the inner side of the sealing gaskets 500 fitting against the outer wall of the ball head 200. Alternatively, the ball head 200 may have a T-shaped water passage 210 inside. This T-shaped water passage allows for arbitrary installation of the ball head 200, improving installation efficiency and eliminating concerns about incorrect installation. Specifically, when the angle valve structure is open, the water passage 210 connects the inlet channel 120 and the outlet channel 410; when the angle valve structure is closed, the ball head 200 blocks the connection between the inlet channel 120 and the outlet channel 410. A first clearance hole is provided in the middle of the sealing gasket 500 near the connector 400.

[0047] Please see Figure 1 , 2 A first external thread 150 is provided on the outer shell 100 and on the outer wall of the water inlet channel 120. The first external thread 150 is close to the opening of the water inlet channel 120. The first external thread 150 can facilitate the installation of the entire angle valve structure onto the wall. The angle valve structure can be locked or tightened by manually rotating the outer shell.

[0048] Please see Figure 3 , 67. A first limiting step 131 is provided on the inner side wall of the opening of the installation channel 130 to limit the rotation of the valve stem 300. A second limiting step 3211 is provided on the valve stem. A limiting groove 132 is formed between the two first limiting steps 131. The second limiting step 3211 rotates within the limiting groove 132 to limit the rotation angle of the valve stem 300. The first limiting step 131 is provided at the opening of the installation channel 130 to facilitate machining, reduce machining difficulty, save machining costs, and improve machining efficiency. Moreover, the first limiting step 131 can not only limit the rotation angle of the valve stem 300, but also restrict the lower part of the valve stem 300 inside the outer shell 100.

[0049] Please see Figure 2 , 4 The valve stem 300 sequentially includes a first connecting section 310, a rotating section 320, a sealing section 330, and a second connecting section 340. The rotating section 320 and the sealing section 330 are located within the mounting channel 130. The valve stem 300 of this invention has an integral structure with sufficient strength, improving its service life. At least one first sealing ring 700 is fitted onto the outer wall of the sealing section 330, and the first sealing ring 700 is located between the sealing section 330 and the mounting channel 130. Specifically, the first connecting section 310 is located outside the outer shell 100 and is used to connect the knob 600; the outer wall of the sealing section 330 is provided with at least one annular groove 331, and the first sealing ring 700 is fitted inside the annular groove 331; the rotating section 320 includes a rotating part 321 and a limiting part 322 located in the installation channel 130. The limiting part 322 is located below the first limiting step 131, and the second limiting step 3211 is located outside the rotating part 321. The first limiting step 131 can not only restrict the rotation of the valve stem 300, but also prevent the valve stem 300 from detaching from the outer shell 100. This not only improves the installation efficiency of the valve stem 300, but also makes the whole structure more stable after the valve stem 300 is installed in place.

[0050] Please see Figure 5 Above the ball head 200, a slot 220 is provided for the second connecting section 340 to be inserted. When using a T-shaped water passage 210, the ball head 200 can be installed arbitrarily, as long as the second connecting section 340 is inserted into the slot 220. After the ball head 200 is installed in place, the second connecting section 340 is inserted into the slot 220, so that rotating the valve stem 300 can drive the ball head 200 to rotate, thereby controlling the opening and closing of the water flow.

[0051] Please see Figure 4 , 67. At least one limiting groove 132 and one limiting step 3211 are provided in this utility model. In this embodiment, two first limiting steps 131 are provided to form two limiting grooves 132, and two second limiting steps 3211 are also provided. Specifically, the first limiting step 131 is provided inside the mounting channel 130 opening, and the limiting groove 132 is formed between the two first limiting steps 131. The limiting step 3211 is located outside the rotating part 321 and abuts against the limiting part 322. The limiting groove 132 and the limiting step 3211 can limit the rotation stroke of the valve stem 300. When the valve stem 300 is at the beginning or end of its stroke, the ball valve structure is in an open or closed state. The limiting groove 132 is directly formed inside the mounting channel 130, making the overall processing more convenient and improving the overall integrity.

[0052] Please see Figure 3 The outer wall of the connector 400 is threaded to the outer shell 100. Specifically, the outer wall of the connector 400 is provided with a second external thread, and the outer shell 100 is provided with an internal thread. The connector 400 is installed by means of threaded connection. At the same time, a second sealing ring 800 is also provided between the connector 400 and the outer shell 100. The outer wall of the connector 400 is also provided with a third external thread to facilitate the connection of other components.

[0053] Please see Figure 1 , 89. The valve stem 300 is rotated relative to the outer casing 100 by the knob 600. The first connecting section 310 is non-cylindrical to facilitate the rotation of the valve stem 300 by the knob 600, while ensuring that it can pass through the installation channel 130. In this embodiment, the upper part of the first connecting section 310 of the valve stem 300 adopts a quadrilateral structure, that is, the cross-section is rectangular or square. The corresponding knob 600 is provided with a connecting groove 611 for matching the quadrilateral structure. The connecting groove 611 can be fixed to the first connecting section 310 by interference fit or glue. The knob 600 includes a handle seat 610, a counterweight 620 disposed in the handle seat 610, and a cover plate 630 disposed on the handle seat 610. The connecting groove 611 is disposed on the handle seat 610, and a first rib is disposed inside the connecting groove 611. 6111, preferably, the center of each of the four sides of the connecting groove 611 is provided with a first rib 6111, which, together with glue, allows the first connecting segment 310 to be better locked in the connecting groove 611. The connecting groove 611 on the handle seat 610 forms a circular step 612 inside the handle seat. Therefore, the counterweight is provided with a first clearance hole 621 to avoid the circular step 612. The inner side wall of the handle seat 610 and the outer side wall of the circular step 612 are provided with a second rib 613. The counterweight 620 can be better restrained in the handle seat 610, and the two are fixed together by glue or other means. The cover plate 630 is directly fixed to the top of the handle seat 610 by glue or other means to cover the counterweight 630, making the overall appearance more beautiful. The counterweight 630 also improves the feel of turning the knob 600.

[0054] The installation method of the angle valve structure of this utility model is as follows:

[0055] The valve stem 300, fitted with the first sealing ring 700, enters through the water inlet channel 120, passes through the water inlet channel 120 and the receiving cavity 110 in sequence, and is then placed into the installation channel 130. A sealing gasket 500 can be inserted from the side opening of the receiving groove, and then the ball head 200 is inserted. When the ball head 200 is inserted, the second connecting section 340 needs to be embedded in the slot 220 to ensure the smooth insertion of the ball head 200 (i.e., the valve stem 300 is in the closed position). Then, the other sealing gasket 500 is inserted, and finally, the connector 400 fitted with the second sealing ring 800 is screwed to the outer shell 100. Example 2

[0056] Please see Figures 12 to 13This is an angle valve structure provided as Embodiment 2 of the present invention. The difference between this embodiment and Embodiment 1 lies in the fixing method between the knob 600 and the valve stem 300, which is fixed by bolts 900. The specific structure of the knob 600 is also different, and the shape of the first connecting section 310 of the valve stem 300 is different. Specifically, the knob 600 includes a handle seat 610, a counterweight 620 disposed within the handle seat 610, and a cover plate 630 disposed on the handle seat 610. In this embodiment, the connecting groove 611 is disposed in… The counterweight 620 has a hollow handle seat 610 with a second clearance hole 614 for the first connecting section 310 to pass through. A stepped hole 622 communicating with the connecting groove 611 is also provided above the counterweight 620. The bolt 900 passes through the stepped hole and is screwed into the first connecting section 310 within the connecting groove 611. This method allows the knob 600 to be better fixed or restrained above the valve stem, preventing it from falling off. An internal threaded hole is provided above the first connecting section 310 for connection with the bolt 900. The first connecting section 310 is non-cylindrical to allow the knob 600 to rotate the valve stem 300, while also ensuring it can pass through the mounting channel 130.

[0057] In summary, the angle valve structure of this utility model, by replacing the existing valve core with a ball head and using the valve stem to drive the ball head to rotate, can greatly improve the flow rate of the angle valve structure. At the same time, the overall structure is simple, requiring no complicated assembly, which not only improves assembly efficiency but also reduces costs. Furthermore, the optimized structure makes the whole unit lighter, reducing transportation costs. Moreover, the first limiting step of this utility model is set at the opening of the installation channel, which is easy to process. The first limiting step can not only limit the rotation angle of the valve stem but also restrict the valve stem to the outer shell.
