Description

Technical Field

[0001] This utility model relates to the field of valve technology for water supply equipment, and more specifically to an adjustable valve for water supply equipment. Background Technology

[0002] In water supply equipment, valves are often used to control, regulate, or cut off water flow. In water supply systems, there may be a high pressure difference on both sides of the valve, especially for valves on the main pipeline. When closed, the water flow impact and pressure will cause the valve disc (such as gate valve and butterfly valve) to experience great resistance. Moreover, the handwheel equipped with the valve is usually not very large in diameter, and a large torque is required to turn the handwheel, which is quite laborious when using it. Therefore, it is urgent to design an adjustable valve for water supply equipment to solve the above problems. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides an adjustable valve for a water supply device to solve the problems existing in the background art.

[0004] This utility model provides the following technical solution: an adjustable valve for a water supply device, including a valve body, a rotating ring, three fixed handle assemblies, and three adjustable handle assemblies. The rotating ring is rotatably mounted on the valve body, and the three fixed handle assemblies and the three adjustable handle assemblies are all circumferentially and equidistantly fixed on the outer circumference of the rotating ring. The fixed handle assembly includes a first fixed rod and a first grip. The first fixed rod is fixedly installed on the outer circumference of the rotating ring, and the first grip is fixedly installed on one end of the first fixed rod. The adjustable handle assembly includes a second fixed rod, a sliding rod, and a second grip. The second fixed rod is fixedly installed on the outer circumference of the rotating ring, the sliding rod is slidably installed on the second fixed rod, and the second grip is movably installed on one end of the sliding rod.

[0005] Furthermore, the adjustable handle assembly also includes a slider, which is fixedly installed inside the sliding rod. A groove is provided on the second fixed rod, and the slider is slidably installed inside the groove.

[0006] Furthermore, the adjustable handle assembly also includes a bending spring, an arc-shaped block, and a plug rod. An arc-shaped groove is provided on the top of the second grip, the arc-shaped block is slidably installed in the arc-shaped groove, the bending spring is fixedly installed between the arc-shaped block and the arc-shaped groove, the plug rod is fixedly installed at one end of the arc-shaped block, and the plug rod slides through the second grip. A slot is provided at one end of the first grip, and the plug rod is adapted to the slot.

[0007] Furthermore, the adjustable handle assembly also includes a spring, a connecting block, and a fixing block.

[0014] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 ~Attached Figure 4 The present invention will be further described below.

[0015] An adjustable valve for a water supply device includes a valve body 1, a rotating ring 2, three fixed handle assemblies 3, and three adjustable handle assemblies 4. The rotating ring 2 is rotatably mounted on the valve body 1, and the three fixed handle assemblies 3 and the three adjustable handle assemblies 4 are all circumferentially fixedly mounted on the outer circumference of the rotating ring 2. The fixed handle assembly 3 includes a first fixed rod 301 and a first grip 302. The first fixed rod 301 is fixedly installed on the outer circumference of the rotating ring 2, and the first grip 302 is fixedly installed on one end of the first fixed rod 301. The adjustable handle assembly 4 includes a second fixed rod 401, a sliding rod 403, and a second grip 407. The second fixed rod 401 is fixedly installed on the outer circumference of the rotating ring 2, the sliding rod 403 is slidably installed on the second fixed rod 401, and the second grip 407 is movably installed on one end of the sliding rod 403.

[0016] Specifically, the adjustable handle assembly 4 also includes a slider 404, which is fixedly installed in the sliding rod 403. A groove 402 is provided on the second fixed rod 401, and the slider 404 is slidably installed in the groove 402.

[0017] Specifically, the adjustable handle assembly 4 also includes a bending spring 409, an arc-shaped block 410, and a plug rod 411. The top of the second grip 407 is provided with an arc-shaped groove 408. The arc-shaped block 410 is slidably installed in the arc-shaped groove 408. The bending spring 409 is fixedly installed between the arc-shaped block 410 and the arc-shaped groove 408. The plug rod 411 is fixedly installed at one end of the arc-shaped block 410 and slides through the second grip 407. One end of the first grip 302 is provided with a slot 303, and the plug rod 411 is adapted to the slot 303.

[0018] In this embodiment, the sliding arc block 410 slides within the arc groove 408 and compresses the bending spring 409. The sliding of the arc block 410 causes the insertion rod 411 to slide out of the slot 303, thereby unlocking the second grip 407.

[0019] Specifically, the adjustable handle assembly 4 also includes a spring 412, a connecting block 413, and a fixing block 414. One end of the sliding rod 403 has a circular groove 405. One end of the spring 412 is fixedly installed on the inner wall of one end of the circular groove 405. The connecting block 413 is fixedly installed on the other end of the spring 412. The fixing block 414 is fixedly installed on the second grip 407. The fixing block 414 and the connecting block 413 are rotatably connected, and both the fixing block 414 and the connecting block 413 can be slidably installed in the circular groove 405.

[0020] Specifically, the adjustable handle assembly 4 also includes two locking blocks 415, which are symmetrically fixed on the fixed block 414. One end of the sliding rod 403 has four slots 406 equidistantly spaced around its circumference, and the locking blocks 415 are adapted to the slots 406.

[0021] Specifically, the top circumference of the arc-shaped block 410 is provided with several grooves at equal intervals.

[0022] In this embodiment, the groove can increase the friction between the arc-shaped block 410 and the user's hand, making it easier for the user to slide the arc-shaped block 410.

[0023] Working principle: When it is necessary to open or close the valve, hold the second handle 407 and then slide the arc-shaped block 410, causing it to slide within the arc-shaped groove 408 and compress the bending spring 409. The sliding of the arc-shaped block 410 will cause the insertion rod 411 to slide out of the slot 303, thereby unlocking the second handle 407. At this time, pulling the second handle 407 and the sliding rod 403 outward will extend the distance between the second handle 407 and the rotating ring 2. The sliding rod 403 will cause the slider 404 to slide within the groove 402. When the slider 404 slides to the end of the groove 402, continue to pull the second handle 407. At this time, the second handle 407 will cause the fixing block 414 and the connecting block 413 to slide outward and stretch the spring 412. Sliding outwards will also cause the two locking blocks 415 to disengage from two of the locking slots 406. At this time, rotating the second grip 407 will cause the fixing block 414 to rotate at one end of the connecting block 413. Rotating the second grip 407 ninety degrees will cause the fixing block 414 to rotate the two locking blocks 415 ninety degrees. Then, releasing the second grip 407 will cause the spring 412 to contract and drive the connecting block 413 and the fixing block 414 to slide into the circular groove 405. At the same time, it will drive the two locking blocks 415 into the other two locking slots 406, locking the second grip 407. At this time, the second grip 407 is in a vertical state, making it easier to pull or push, and it is farther away from the rotating ring 2. According to the lever principle, the force required to pull or push the second grip 407 will be smaller.

[0024] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
