Description

Technical Field

[0001] This utility model relates to the field of ball valve technology, specifically to a ball valve ball that prevents misalignment. Background Technology

[0002] A ball valve is a type of valve that controls the flow of fluid by rotating a ball.

[0003] The opening and closing element of a ball valve is a ball with a circular through-hole, which is connected to the valve stem. When the handle or actuator rotates the valve stem, the ball also rotates. After the ball rotates 90 degrees, it changes the shape of the channel inside the valve body, thereby opening or closing the valve. Specifically, when the ball rotates to a certain position, its orifice aligns with or offsets from the channel of the valve body, thus controlling the flow of fluid.

[0004] During fluid transport, the fluid impacts the ball, causing it to rotate within the valve body. This impact can lead to a misalignment of the ball's rotational position, affecting fluid transport and hindering the use of the ball valve. Therefore, we propose a ball valve ball designed to prevent misalignment. Utility Model Content

[0005] The purpose of this invention is to provide a ball valve ball that prevents misalignment, so as to solve the problems mentioned in the background art.

[0006] A ball valve ball for preventing misalignment, comprising a ball valve and an anti-misalignment unit disposed on the ball valve, the anti-misalignment unit comprising:

[0007] A connecting seat is provided on the ball valve, and a rotating rod is fixedly connected inside the connecting seat. A drive motor is fixedly connected to the end of the rotating rod.

[0008] A fixing base is fixedly connected to a connecting base, and a slot is provided in the fixing base;

[0009] The snap-fit ​​connector is inserted into the slot of the fixed base, and the rotation of the fixed base is limited by the snap-fit ​​connector.

[0010] Preferably, the ball valve includes:

[0011] Valve body;

[0012] A ball is rotatably connected inside the valve body, and the end of the ball is fixedly connected to the connecting seat.

[0013] Preferably, a telescopic rod is fixedly connected to the top end face of the snap-fit ​​seat, and a compression seat is fixedly connected to the top end face of the telescopic rod.

[0014] Preferably, a spring is sleeved on the outer peripheral wall of the telescopic rod, and the two ends of the spring are fixedly connected to the compression seat and the snap-fit ​​seat, respectively.

[0015] Preferably, the top end face of the compression seat is fixedly connected to the push seat.

[0016] Preferably, a connecting flange is bolted to the top end face of the valve body, and the connecting flange is located above the compression seat.

[0017] Preferably, the push seat is slidably connected to the inner wall of the connecting flange, and the push seat and the connecting flange are fixed by bolts.

[0018] By adopting the above technical solution, the rotation of the ball within the valve body is limited, and the position of the ball within the valve body is limited, thus ensuring the normal and stable transmission of liquid.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: When the sphere is transporting fluid, the fluid impact causes the sphere to shake. At this time, the sphere drives the connecting seat and the fixed seat to rotate. The rotation of the fixed seat generates a thrust on the locking seat. Under the reaction force of the spring, a push is generated on the locking seat, limiting the rotation of the fixed seat. Even when the impact force is too large, causing the fixed seat to push the locking seat to move, the locking seat pushes the spring to compress, increasing the spring's thrust on the locking seat and further limiting the rotation of the locking seat, thereby limiting the rotation of the connecting seat and the sphere. When the fluid impact force disappears, under the push of the spring, the locking seat is pushed to squeeze the fixed seat, pushing the sphere to rotate to the initial position, avoiding affecting normal fluid transmission.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1:

[0026] Please see Figs. 1-3 This utility model provides a technical solution: a ball valve ball for preventing misalignment, comprising a ball valve 1 and an anti-misalignment unit 2 disposed on the ball valve 1, the anti-misalignment unit 2 comprising:

[0027] A connecting seat 21 is mounted on the ball valve 1. A rotating rod is fixedly connected inside the connecting seat 21, and a drive motor is fixedly connected to the end of the rotating rod. The drive motor is a mature existing structure, model YE2-112M-4, which will not be described in this application.

[0028] The fixing seat 22 is fixedly connected to the connecting seat 21, and the fixing seat 22 has a slot.

[0029] The locking socket 23 is inserted into the slot of the fixing seat 22, and the rotation of the fixing seat 22 is limited by the locking socket 23.

[0030] Ball valve 1 includes:

[0031] Valve body 11;

[0032] The ball 12 is rotatably connected inside the valve body 11. The end of the ball 12 is fixedly connected to the connecting seat 21. When it is necessary to rotate the ball 12 to control the opening and closing of the valve, the connecting seat 21 is driven to rotate by the drive motor, so that the ball 12 rotates in the valve body 11 to control the opening and closing of the valve.

[0033] A telescopic rod 24 is fixedly connected to the top end face of the snap-fit ​​seat 23, and a compression seat 26 is fixedly connected to the top end face of the telescopic rod 24.

[0034] A spring 25 is sleeved on the outer periphery of the telescopic rod 24. The two ends of the spring 25 are fixedly connected to the compression seat 26 and the snap-fit ​​seat 23 respectively. When the ball 12 is transporting fluid, the fluid impact causes the ball 12 to shake. At this time, the ball 12 drives the connecting seat 21 and the fixed seat 22 to rotate. Under the rotation of the fixed seat 22, a thrust is generated on the snap-fit ​​seat 23.

[0035] Under the reaction force of the spring 25, a push is generated on the locking seat 23, which limits the rotation of the fixed seat 22. Even when the impact force is too large, the fixed seat 22 pushes the locking seat 23 to move. At this time, the locking seat 23 pushes the spring 25 to compress, which increases the thrust of the spring 25 on the locking seat 23, further limiting the rotation of the locking seat 23, and thus limiting the rotation of the connecting seat 21 and the ball 12.

[0036] When the fluid impact force disappears, the spring 25 pushes the snap-fit ​​seat 23 to press against the fixed seat 22, pushing the ball 12 to rotate to the initial position, thus avoiding affecting normal fluid transmission.

[0037] The top end face of the compression seat 26 is fixedly connected to the push seat 27.

[0038] When the control ball 12 rotates in the valve body 11, the ball 12 drives the connecting seat 21 to rotate, causing the fixed seat 22 to push the snap-fit ​​seat 23 to move upward. When fully closed, the snap-fit ​​seat 23 coincides with the slot on the fixed seat 22. At this time, under the rebound of the spring 25, the snap-fit ​​seat 23 is pushed to re-insert into the fixed seat 22, thus limiting the position of the ball 12.

[0039] Example 2:

[0040] A connecting flange 28 is bolted to the top end face of the valve body 11, and the connecting flange 28 is located above the compression seat 26.

[0041] The push seat 27 is slidably connected to the inner wall of the connecting flange 28, and the push seat 27 and the connecting flange 28 are fixed by bolts;

[0042] When it is necessary to change the limiting force of the locking seat 23 on the fixed seat 22 according to the impact of the water flow on the ball 12, the bolts between the push seat 27 and the connecting flange 28 are removed, and the push seat 27 is pushed to drive the compression seat 26 to move. At this time, the telescopic rod 24 extends and retracts, and the compression seat 26 further compresses the spring 25, increasing the compression force of the spring 25 on the locking seat 23.

[0043] Working principle: When ball valve 1 is needed for liquid transfer, the drive motor drives the connecting seat 21 to rotate, so that the ball 12 rotates in the valve body 11, thereby controlling the opening and closing of the valve.

[0044] When the ball 12 rotates 90 degrees in the valve body 11, the ball 12 is opened to the maximum, and the fluid is transported through the valve body 11 and the ball 12.

[0045] When the control ball 12 rotates in the valve body 11, the ball 12 drives the connecting seat 21 to rotate, causing the fixed seat 22 to push the snap-fit ​​seat 23 to move upward. When fully closed, the snap-fit ​​seat 23 coincides with the slot on the fixed seat 22. At this time, under the rebound of the spring 25, the snap-fit ​​seat 23 is pushed to re-insert into the fixed seat 22, thus limiting the position of the ball 12.

[0046] When the ball 12 is transporting fluid, the fluid impact causes the ball 12 to shake. At this time, the ball 12 drives the connecting seat 21 and the fixed seat 22 to rotate. Under the rotation of the fixed seat 22, a thrust is generated on the snap-fit ​​seat 23.

[0047] Under the reaction force of the spring 25, a push is generated on the locking seat 23, which limits the rotation of the fixed seat 22. Even when the impact force is too large, the fixed seat 22 pushes the locking seat 23 to move. At this time, the locking seat 23 pushes the spring 25 to compress, which increases the thrust of the spring 25 on the locking seat 23, further limiting the rotation of the locking seat 23, and thus limiting the rotation of the connecting seat 21 and the ball 12.

[0048] When the fluid impact force disappears, the spring 25 pushes the snap-fit ​​seat 23 to press against the fixed seat 22, pushing the ball 12 to rotate to the initial position, thus avoiding affecting normal fluid transmission.

[0049] When it is necessary to change the limiting force of the locking seat 23 on the fixed seat 22 according to the impact of the water flow on the ball 12, the bolts between the push seat 27 and the connecting flange 28 are removed, and the push seat 27 is pushed to drive the compression seat 26 to move. At this time, the telescopic rod 24 extends and retracts, and the compression seat 26 further compresses the spring 25, increasing the compression force of the spring 25 on the locking seat 23.
