Description

Technical Field

[0001] This utility model belongs to the field of angle valve technology, specifically a simple high-flow angle valve. Background Technology

[0002] Angle valves are commonly used control components in fluid pipeline systems and are widely used in scenarios such as domestic water supply and industrial fluid transportation. Especially in situations where flow regulation and on / off control are required (such as water equipment in bathrooms and kitchens, or spray gun connections in high-pressure cleaning operations), the application demand for high-flow angle valves continues to grow because they can meet the needs of high-flow fluid transportation.

[0003] In existing technologies, the structure of a high-flow angle valve typically includes a valve body, valve core, valve stem, inlet pipe, and outlet pipe. By rotating the valve stem, the valve core is moved to achieve the opening and closing of the pipeline and the regulation of the flow rate. When it is necessary to connect a hose spray gun to the outlet of the high-flow angle valve (such as for high-pressure cleaning, precision water supply, etc.), the existing connection methods mostly rely on the connection structure at the end of the spray gun hose to directly match the outlet of the angle valve. Common matching forms include threaded connection, snap-fit ​​connection, or flange connection.

[0004] Among them, threaded connection is the most widely used method in the existing technology, which is to fix it by screwing the internal thread of the spray gun hose connection end with the external thread of the angle valve outlet. Snap-fit ​​connection is fixed by the elastic snap on the connection structure engaging with the slot of the outlet. Flange connection is suitable for larger flow scenarios, but it needs to be tightened with bolts.

[0005] The existing technology has the following shortcomings:

[0006] The process of fixing and disassembling is often quite laborious: when using threaded connections, in order to ensure sealing performance and connection stability, the threads of the hose connection end and the angle valve outlet need to be fully screwed together, and tools are often needed to apply a large torque. This is not only cumbersome to operate, but also easy to cause thread wear after repeated disassembly and assembly, further increasing the difficulty of disassembly and assembly.

[0007] When using snap-fit ​​connections, existing snap-fit ​​structures often rely on a single elastic element to provide the locking force. To prevent the connection from falling off under high flow and high water pressure, the locking force is usually designed to be large, which means that a large external force is required to separate the snap-fit ​​during disassembly, making the operation inconvenient. Utility Model Content

[0008] To overcome the above-mentioned defects, this utility model provides a simple high-flow angle valve, which solves the technical problems mentioned in the background art.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a simple high-flow angle valve, comprising an angle valve body, a valve core threadedly connected to the inner side of the angle valve body, a valve cover rotatably connected to the top of the angle valve body, a valve stem disposed between the valve cover and the valve core, an inlet pipe disposed at the bottom of the angle valve body, an outlet pipe opened on one side of the angle valve body, a first fixing ring integrally formed on the outer side of the outlet pipe, a sleeve threadedly connected to the outer side of the outlet pipe, a second fixing ring fixedly connected to one end of the sleeve, and a ring spring disposed on the inner side of the second fixing ring. The annular spring has multiple sets of compression blocks on its outer side, and the compression blocks movably penetrate the sleeve. The end of the sleeve is snapped with a connecting pipe, and the outside of the connecting pipe is fixedly connected to multiple sets of connecting rods. The connecting rods are snapped with the compression blocks. A rotating ring is rotatably connected to the outside of the sleeve, and a first magnetic block is fixedly connected to the outside of the rotating ring. The ends of the connecting rods are all fixedly connected to second magnetic blocks. The first magnetic block and the second magnetic block are magnetically attracted to each other. The two sides of the first magnetic block are fixedly connected with baffles that cooperate with the first magnetic block in a symmetrical structure.

[0010] As a further embodiment of this utility model: the inner side of the extrusion block is provided with a slot for use with the annular spring, and a movable plate is fixedly connected to the bottom of the extrusion block. The inner side of the movable plate has a semi-arc structure, and the movable plate is located inside the sleeve.

[0011] As a further embodiment of this utility model: a waterproof block is fixedly provided at one end of the connecting pipe, the waterproof block is located inside the sleeve, and an annular mounting groove for use with the waterproof block is provided at the end of the sleeve.

[0012] As a further embodiment of this utility model: an annular groove is provided on the outer side of the sleeve to cooperate with the annular spring, a first movable groove is provided on the inner side of the sleeve to cooperate with the extrusion block, and a second movable groove is provided on the outer side of the second fixed ring to cooperate with the extrusion block.

[0013] As a further embodiment of this utility model: the water inlet pipe has an external thread on its outer side, and the connecting pipe has an internal thread on its outer side.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. Through the threaded connection between the sleeve and the outlet pipe, the cooperation between the first fixing ring and the second fixing ring, the snap-fit ​​connection between the squeezing block and the connecting rod, and the magnetic fixation of the magnetic block, a multi-layered stable structure is formed. When water is flowing, the water pressure can enhance the fitting effect of the squeezing block, effectively preventing the connecting pipe from falling off under high water pressure, and improving the reliability of use in high flow scenarios.

[0016] 2. Disassembly is easy without the need for strenuous threading. Simply close the valve core and use the ring spring's reset action and magnetic attraction for convenient separation. This makes the operation more labor-saving and convenient. Meanwhile, the design of various components, such as the threaded connection between the sleeve and the water outlet pipe, and the snap-fit ​​connection between the connecting pipe and the sleeve, ensures both tightness and sealing of the assembly, reducing the risk of leakage. Furthermore, the integrally formed first fixing ring and snap-fit ​​components in the overall structure not only ensure structural stability but also reduce assembly difficulty. It can be adapted to use with spray guns without large-scale modifications, improving versatility and practicality. Attached Figure Description

[0023] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0024] like Figures 1-5 As shown, this utility model provides a technical solution:

[0025] A simple high-flow angle valve includes a valve body 1, a valve core 2 threadedly connected to the inside of the valve body 1, a valve cover 3 rotatably connected to the top of the valve body 1, a valve stem disposed between the valve cover 3 and the valve core 2, an inlet pipe 4 disposed at the bottom of the valve body 1, an outlet pipe 5 disposed on one side of the valve body 1, a first fixing ring 6 integrally formed on the outside of the outlet pipe 5, a sleeve 7 threadedly connected to the outside of the outlet pipe 5, a second fixing ring 8 fixedly connected to one end of the sleeve 7, an annular spring 11 disposed inside the second fixing ring 8, and multiple sets of ring springs disposed outside the annular spring 11. The extrusion block 12 is movably connected through the sleeve 7. The end of the sleeve 7 is snapped to the connecting tube 14. Multiple sets of connecting rods 16 are fixedly connected to the outside of the connecting tube 14. The connecting rods 16 are snapped to the extrusion block 12. A rotating ring 9 is rotatably connected to the outside of the sleeve 7. A first magnetic block 10 is fixedly connected to the outside of the rotating ring 9. A second magnetic block 17 is fixedly connected to the end of each connecting rod 16. The first magnetic block 10 and the second magnetic block 17 are magnetically attracted to each other. Baffles that cooperate with the first magnetic block 10 are fixedly connected to both sides of the first magnetic block 10 in a symmetrical structure.

[0026] Specifically, during installation, first connect the water inlet pipe 4 at the bottom of the angle valve body 1 to the external water inlet end securely. Then, align the connecting pipe 14 (external spray gun hose) with the end of the sleeve 7 and snap it together. During this process, the connecting rod 16 on the outside of the connecting pipe 14 will form a snap-fit ​​with the compression block 12 that moves through the sleeve 7. At the same time, rotate the rotating ring 9 on the outside of the sleeve 7 so that the first magnetic block 10 on the rotating ring 9 and the second magnetic block 17 at the end of the connecting rod 16 are magnetically attracted to achieve initial fixation. The baffles on both sides of the first magnetic block 10 can prevent the position from shifting during the magnetic attraction process. Then, rotate the valve stem by rotating the valve cover 3 at the top of the angle valve body 1, which drives the valve core 2 to adjust the thread inside the angle valve body 1, thus completing the overall assembly.

[0027] When water is supplied, valve core 2 is opened, and water flows from inlet pipe 4 into angle valve body 1, and then through outlet pipe 5 to sleeve 7 and connecting pipe 14. At this time, water pressure will push the squeezing block 12 inside sleeve 7, so that it will fit more deeply with the snap-fit ​​structure of connecting pipe 14 under the cooperation of ring spring 11. At the same time, the magnetic attraction of the first magnetic block 10 and the second magnetic block 17 is further strengthened, ensuring that the connection between connecting pipe 14 and sleeve 7 is stable and avoiding separation due to excessive water pressure.

[0028] When disassembling, first close the valve core 2 to stop the water flow. After the water pressure disappears, the ring spring 11 drives the squeezing block 12 to reset. Then, directly pull the connecting pipe 14 out from the end of the sleeve 7 to separate the first magnetic block 10 from the second magnetic block 17 and release the magnetic fixation to complete the disassembly.

[0029] Through the threaded connection between the sleeve 7 and the outlet pipe 5, the cooperation between the first fixing ring 6 and the second fixing ring 8, the snap-fit ​​connection between the squeezing block 12 and the connecting rod 16, and the magnetic fixation of the magnetic block, a multi-layered stable structure is formed. When water is flowing, the water pressure can enhance the fitting effect of the squeezing block 12, effectively preventing the connecting pipe 14 from falling off under high water pressure, and improving the reliability of use in high flow scenarios.

[0030] During disassembly, there is no need to forcefully tighten the threads. Simply close the valve core 2 and use the reset action of the ring spring 11 and the convenient separation of the magnetic attraction to easily complete the disassembly. The operation is more labor-saving and convenient. At the same time, the design of each component, such as the threaded connection between the sleeve 7 and the water outlet pipe 5, and the snap-fit ​​connection between the connecting pipe 14 and the sleeve 7, takes into account the tightness and sealing of the assembly, reducing the risk of water leakage. In addition, the integrally formed first fixing ring 6 and snap-fit ​​components in the overall structure not only ensure the structural stability, but also reduce the assembly difficulty. It can be adapted to the spray gun hose without large-scale modification, and has strong versatility and practicality.

[0031] The inner side of the extrusion block 12 is provided with a slot 18 for use with the annular spring 11. The bottom of the extrusion block 12 is fixedly connected to a movable plate 13. The inner side of the movable plate 13 has a semi-arc structure. The movable plate 13 is located inside the sleeve 7. One end of the connecting pipe 14 is fixedly provided with a waterproof block 15. The waterproof block 15 is located inside the sleeve 7. The end of the sleeve 7 is provided with an annular mounting groove for use with the waterproof block 15. The outer side of the sleeve 7 is provided with an annular groove 21 for use with the annular spring 11. The inner side of the sleeve 7 is provided with a first movable groove 19 for use with the extrusion block 12. The outer side of the second fixed ring 8 is provided with a second movable groove 20 for use with the extrusion block 12. The outer side of the water inlet pipe 4 is provided with an external thread. The outer side of the connecting pipe 14 is provided with an internal thread.

[0032] Specifically, during installation, the angle valve body 1 is first securely connected to the external water inlet end through the external thread on the outside of the water inlet pipe 4. Then, the waterproof block 15 at one end of the connecting pipe 14 is aligned with the annular mounting groove at the port of the sleeve 7 and embedded, so that the waterproof block 15 is located inside the sleeve 7 to achieve a preliminary seal.

[0033] Then, the annular spring 11 is placed in the annular groove 21 on the outside of the sleeve 7. The pressing block 12 is engaged with the annular spring 11 through the inner slot 18. At the same time, the pressing block 12 passes through the first movable slot 19 of the sleeve 7 and the second movable slot 20 of the second fixed ring 8. The semi-arc movable plate 13 at its bottom is placed inside the sleeve 7. At this time, after the connecting pipe 14 is connected to the sleeve 7, the movable plate 13 can fit against the outer wall of the connecting pipe 14 for auxiliary positioning.

[0034] When water is supplied, the water pressure pushes the movable plate 13, which in turn moves the squeezing block 12 along the first and second movable grooves 20. The annular spring 11 deforms with the squeezing block 12 due to the limiting effect of the slot 18, further strengthening the squeezing block 12's fixation of the connecting pipe 14. At the same time, the waterproof block 15 fits tightly with the annular mounting groove to improve the sealing performance.

[0035] When disassembling, turn off the water supply. The ring spring 11 will reset and drive the squeezing block 12 and the movable plate 13 to move back. Then, pull out the connecting pipe 14 directly. The waterproof block 15 will detach from the ring mounting groove.

[0036] The working principle of this utility model is as follows:

[0037] First, the angle valve body 1 is securely connected to the external water inlet end using the external thread on the outside of the water inlet pipe 4. Then, the sleeve 7 is connected to the external thread of the water outlet pipe 5. The position of the sleeve 7 is limited by the cooperation of the first fixing ring 6 and the second fixing ring 8. At the same time, the annular spring 11 is placed in the annular groove 21 on the outside of the sleeve 7, so that the squeezing block 12 is engaged with the annular spring 11 through the inner slot 18 and passes through the first movable groove 19 of the sleeve 7 and the second movable groove 20 of the second fixing ring 8, so that the semi-arc movable plate 13 at the bottom of the squeezing block 12 is located inside the sleeve 7, thus completing the basic assembly of the angle valve body 1 and the connecting parts.

[0038] Secondly, the waterproof block 15 at one end of the connecting pipe 14 is embedded into the annular mounting groove at the port of the sleeve 7 to achieve initial sealing. At the same time, the connecting rod 16 on the outside of the connecting pipe 14 and the compression block 12 form a snap-fit ​​engagement. Then, the rotating ring 9 on the outside of the sleeve 7 is rotated so that the first magnetic block 10 and the second magnetic block 17 at the end of the connecting rod 16 are magnetically attracted. The baffles on both sides of the first magnetic block 10 prevent magnetic displacement, forming a double fixation of snap-fit ​​and magnetic attraction. Then, by rotating the valve cover 3 on the top of the angle valve body 1, the valve stem is driven to adjust the valve core 2 to achieve the on / off control of the water circuit.

[0039] It is worth mentioning that when water is supplied, the water pressure will further enhance the connection stability and sealing. After the valve core 2 is opened, the water flows from the inlet pipe 4 into the angle valve body 1, and flows through the outlet pipe 5 to the sleeve 7 and the connecting pipe 14. At this time, the water pressure pushes the movable plate 13, which drives the squeezing block 12 to move along the first and second movable grooves 20. The ring spring 11 is limited by the slot 18 and deforms with the squeezing block 12, so that the squeezing block 12 fits the buckle structure of the connecting pipe 14 more deeply. At the same time, the waterproof block 15 fits tightly with the ring mounting groove under the action of water pressure. The magnetic attraction is also more stable with the enhanced connection tightness, effectively preventing the connecting pipe 14 from falling off and leaking under high water pressure.

[0040] Finally, after the water circuit is closed, each component can automatically reset to achieve convenient disassembly. After the valve core 2 is closed and the water supply is stopped, the water pressure disappears, and the ring spring 11 drives the squeezing block 12 and the movable plate 13 to reset. The magnetic attraction of the first magnetic block 10 and the second magnetic block 17 can be easily separated. The disassembly can be completed by directly pulling out the connecting pipe 14 without having to twist the threads. The operation is convenient.

[0041] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
