Description

Technical Field

[0001] This utility model relates to the field of angle valve technology, and in particular to an angle valve that prevents accidental opening. Background Technology

[0002] Most angle valves currently on the market use a single rotary control structure, lacking specific anti-accidental opening designs. This makes them prone to safety hazards in daily use due to unforeseen circumstances. For example, in high-water-use scenarios such as kitchens and bathrooms, angle valves may be accidentally opened due to accidental contact with a person's body, scratches from cleaning tools, or children turning the control components out of curiosity. This not only wastes tap water but may also lead to secondary problems such as flooded floors, damp furniture, and even slips and falls, causing inconvenience and property damage to users. Furthermore, while some existing angle valves attempt to incorporate simple limit structures, these are mostly single-protection mechanisms with limited effectiveness in preventing accidental opening and cannot comprehensively address various accidental operation scenarios. Utility Model Content

[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide an angle valve that prevents accidental opening. Traditional angle valves are prone to safety hazards due to accidental contact, accidental operation, or child misoperation. Through a dual protection mechanism, the push block is first rotated to align with the limiting structure, and then the button is pressed to unlock, which solves the problem of water flow accidental due to unintentional operation. At the same time, the problem of insufficient sealing performance and easy leakage of traditional angle valves is also solved. By using the seals between the valve core and the valve body, between the rotating rod and the valve core, and the gasket under the valve core, the leakage path is blocked, which can solve the problems of water leakage and component corrosion.

[0004] This utility model also provides an angle valve with the above-mentioned method for preventing accidental opening, comprising: a valve body, a valve core threadedly connected to the inner side wall of the valve body, a rotating rod slidably connected to the inner side wall of the valve core, a rotating block fixedly connected to one end of the rotating rod, a ceramic plate one detachably connected to the lower surface of the rotating block, a ceramic plate two detachably connected to the inner side wall of the valve core, and a gasket detachably connected to the lower surface of the valve core. A spring is fixedly connected to the lower bottom wall of the rotating rod. A connecting rod is fixedly connected to the end of the spring away from the rotating rod. A sliding rod is fixedly connected to the side surface of the connecting rod, and a stop is slidably connected to the side surface of the sliding rod. Through these components and a dual protection mechanism, the control component can only be rotated after the push block is rotated to align the limiting structure and then pressed to unlock it. This effectively prevents accidental contact, accidental operation, or child misoperation from opening the angle valve, significantly improving safety.

[0005] According to the present invention, an angle valve for preventing accidental opening is provided, wherein a push block is rotatably connected to the end of the connecting rod away from the spring, and a locking block is fixedly connected to the side surface of the push block, allowing the push block to move within a rotating groove.

[0006] According to the present invention, an angle valve designed to prevent accidental opening is provided with a rotating groove at the end of the rotating rod away from the rotating block, and the push block is movably connected to the rotating rod. The push block can only be pressed when the locking block aligns with the groove on the rotating groove.

[0007] According to the present invention, an angle valve for preventing accidental opening is provided, wherein the side surface of the stop block is slidably connected to the rotating rod, and the end of the stop block away from the sliding rod is in contact with the valve core during operation. The stop block is engaged with the valve core, thereby restricting the movement of the rotating rod.

[0008] According to the present invention, an angle valve for preventing accidental opening is provided, wherein the side surface of ceramic plate one is rotatably connected to the valve core, and the end of ceramic plate one away from the rotating block is attached to ceramic plate two. The opening and closing state of the angle valve is controlled by ceramic plate one and ceramic plate two.

[0009] According to the present invention, an angle valve for preventing accidental opening includes a sealing ring fixedly connected to the side surface of the valve core, the sealing ring being located between the valve core and the valve body. The sealing ring enhances the sealing and securing effect between the valve core and the valve body.

[0010] According to the present invention, an angle valve for preventing accidental opening includes a second sealing ring fixedly connected to the side surface of the rotating rod, located between the rotating rod and the valve core. The second sealing ring enhances the sealing effect between the rotating rod and the valve core.

[0011] According to the present invention, an angle valve for preventing accidental opening has an outlet fixedly connected to the side surface of the valve body, and an inlet fixedly connected to the end of the valve body away from the valve core. This allows water to enter from the inlet below the angle valve and flow out from the outlet on the side of the valve body.

[0012] Beneficial effects: This technical solution's angle valve, designed to prevent accidental opening, employs a dual protection mechanism. Users must first rotate the push block to align the limiting structure, then press to unlock before rotating the control component. This effectively prevents accidental opening due to contact, accidental operation, or child error, significantly improving safety. Simultaneously, the device features a multi-layered sealing structure. Seals between the valve core and valve body, and between the rotating rod and valve core, along with a gasket beneath the valve core, effectively block water leakage paths, reducing the risk of leakage and ensuring sealing reliability and lifespan. Furthermore, the rotation of the ceramic disc adjusts the water flow, providing precise and stable control. The water flow state can be flexibly switched according to actual needs. The rational connection of all components balances ease of operation and structural stability, making it suitable for various water usage scenarios, including household and industrial applications, and highly practical.

[0015] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0016] Reference Figure 1-6 This utility model provides an angle valve to prevent accidental opening, comprising: a valve body 1, a valve core 4 threadedly connected to the inner side wall of the valve body 1, a rotating rod 5 slidably connected to the inner side wall of the valve core 4, a rotating block 11 fixedly connected to one end of the rotating rod 5, a ceramic plate 12 detachably connected to the lower surface of the rotating block 11, a side surface of the ceramic plate 12 rotatably connected to the valve core 4, an end of the ceramic plate 12 away from the rotating block 11 being fitted with a ceramic plate 13, a ceramic plate 13 detachably connected to the inner side wall of the valve core 4, and a washer 7 detachably connected to the lower surface of the valve core 4; Specifically, the valve body 1 is equipped with a valve core 4. During use, the rotating rod 5 inside the valve core 4 is rotated, which drives the ceramic disc 12 to rotate through the rotating block 11. This adjusts the alignment of the through holes on the ceramic disc 12 and the ceramic disc 13 to control the water flow. When the through holes on the ceramic disc 12 and the ceramic disc 13 are fully aligned, the water flows through; when they are misaligned, the water flow is blocked. A washer 7 is also installed below the valve core 4. The washer 7 is located between the valve core 4 and the water inlet 3 of the valve body 1 to improve the sealing between the valve core 4 and the valve body 1. A spring 15 is fixedly connected to the lower bottom wall of the rotating rod 5. A connecting rod 14 is fixedly connected to the end of the spring 15 away from the rotating rod 5. A sliding rod 17 is fixedly connected to the side surface of the connecting rod 14. A stop block 9 is slidably connected to the side surface of the sliding rod 17. The side surface of the stop block 9 is slidably connected to the rotating rod 5. The end of the stop block 9 away from the sliding rod 17 is in contact with the valve core 4 during operation.

[0017] Specifically, the rotating rod 5 has stops 9 on both sides, and the connecting rod 14 and the stops 9 are connected by the slide rod 17. When the angle valve needs to be opened, the connecting rod 14 is pressed by the push block 6. The connecting rod 14 will drive the slide rod 17 to move downward and compress the spring 15. At the same time, the slide rod 17 will slide along the groove on the stop 9, thereby driving the stop 9 to slide into the rotating rod 5, releasing the locking state between the rotating rod 5 and the valve core 4. Thus, the rotating rod 5 can be rotated, driving the ceramic disc 12 to rotate. After use, the rotating rod 5 is reset and the push block 6 is released. At this time, the spring 15 will push the connecting rod 14 to reset, thereby causing the slide rod 17 to drive the stop 9 to re-lock into the groove in the valve core 4, so that the rotating rod 5 can no longer rotate.

[0018] A push block 6 is rotatably connected to the end of the connecting rod 14 away from the spring 15. A locking block 16 is fixedly connected to the side surface of the push block 6. A rotating groove 18 is provided at the end of the rotating rod 5 away from the rotating block 11. The push block 6 is movably connected to the rotating rod 5.

[0019] Specifically, the end of the connecting rod 14 is equipped with a push block 6, and both ends of the push block 6 are provided with locking blocks 16. Before use, the locking blocks 16 on the push block 6 limit the push block 6 so that the push block 6 can only rotate within the rotating groove 18. When in use, the push block 6 is rotated so that the locking blocks 16 can be aligned with the through groove on the rotating groove 18. Only then can the push block 6 be used to push the connecting rod 14 to release the locking state of the rotating rod 5. Through the double protection method, the angle valve is prevented from being opened by mistake.

[0020] A sealing ring 8 is fixedly connected to the side surface of the valve core 4. The sealing ring 8 is located between the valve core 4 and the valve body 1. A sealing ring 10 is fixedly connected to the side surface of the rotating rod 5. The sealing ring 10 is located between the rotating rod 5 and the valve core 4. An outlet 2 is fixedly connected to the side surface of the valve body 1. An inlet 3 is fixedly connected to the end of the valve body 1 away from the valve core 4.

[0021] Specifically, the rotating rod 5 and the valve core 4 are respectively equipped with sealing ring 10 and sealing ring 8 to improve the overall sealing effect of the angle valve. The valve body 1 is also provided with inlet 3 and outlet 2. When opened, the water flows into the valve core 4 from the inlet 3 below the valve body 1 and flows out from the through hole on the valve core 4, so that the water flows out from the outlet 2.

[0022] Working principle: Before use, rotate the push block 6 to align the locking block 16 on the side surface of the push block 6 with the through groove of the rotating groove 18 at the end of the rotating rod 5. Then, press the push block 6 to move the connecting rod 14 down and compress the spring 15. The sliding rod 17 on the side surface of the connecting rod 14 slides along the sliding groove of the stop block 9, causing the stop block 9 to retract into the rotating rod 5, releasing the locking state between the rotating rod 5 and the valve core 4. After unlocking, rotate the rotating rod 5, and the rotating block 11 at one end drives the ceramic disc 12 to rotate. The water flow is controlled by adjusting the alignment of the ceramic disc 12 with the through hole of the ceramic disc 13 on the inner wall of the valve core 4. When the through holes are fully aligned, the water... The water flows in through the inlet 3 of the valve body 1, passes through the valve core 4, and exits through the outlet 2. When the through hole is misaligned, the water flow is blocked. When closing, first rotate the rotating rod 5 in the opposite direction to misalign the through holes of ceramic disc 12 and ceramic disc 13 to cut off the flow. Then release the push block 6, the spring 15 returns to its original position and pushes the connecting rod 14. The slide rod 17 drives the stop block 9 to re-engage in the groove of the valve core 4. Finally, turn the push block 6 back to limit the position of the locking block 16 to achieve double locking to prevent accidental opening. At the same time, the sealing ring 8 between the valve core 4 and the valve body 1, the sealing ring 10 between the rotating rod 5 and the valve core 4, and the gasket 7 between the valve core 4 and the inlet 3 together ensure the sealing performance of the angle valve.

However, the present utility model 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 utility model.
