Description

Technical Field

[0001] This utility model relates to the field of ball valve technology, and more specifically, to a ball valve that is easy to open. Background Technology

[0002] Ball valves, as a common type of fluid control valve, are widely used in various pipeline systems. In traditional ball valves, the ball is usually in direct contact with the valve body or seat, and the ball is rotated by a drive component to achieve the cutting off or opening of the flow path.

[0003] Most existing ball valves use surface contact or bushing contact between the ball and valve body, resulting in significant frictional resistance during rotation and making opening and closing difficult, especially in high-pressure, large-diameter valves. Furthermore, the ball is prone to wear and sinking after prolonged use, further increasing rotational resistance and affecting the smoothness of opening and closing. To address these issues, some existing technologies incorporate support structures within the valve body to support the ball. However, these structures are mostly fixed or integral, failing to effectively reduce friction between the ball and valve body. They also lack convenience for ball disassembly and maintenance; repairs or ball replacement often require removing the entire valve from the pipeline, which is time-consuming and labor-intensive. Therefore, there is an urgent need for a ball valve structure that allows for flexible rotation and easy disassembly and assembly to improve operational convenience and maintenance efficiency. Utility Model Content

[0008] This utility model has the following advantages: through the cooperation of the bottom replacement port and the arc-shaped rotating groove, the lower rotating part can be rotated and inserted into the replacement port, and then locked by the fixing part. During installation, only the lower rotating part needs to be rotated to complete the positioning. During disassembly, the ball can be removed by reversing the operation. There is no need to disassemble the valve body, which significantly improves the efficiency of ball disassembly and maintenance.

[0011] The present invention is further configured such that: a limiting groove is formed on the upper rotating part, and a limiting protrusion that cooperates with the limiting groove is protruding on the valve body.

[0012] The present invention has the following effects: the limiting groove of the upper rotating part cooperates with the limiting protrusion on the valve body to circumferentially limit the upper rotating part, prevent it from rotating with the ball, ensure that the upper rotating part remains fixed in the valve body, and make the ball rotate smoothly.

[0013] The present invention is further configured such that: a control groove is provided on the upper rotating part, the driving member passes through the control groove and is connected to the ball, a cross groove is formed on the connecting part, and a plug-in part protruding on the driving member to cooperate with the cross groove.

[0019] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] Reference Figures 1 to 4 The embodiments of this utility model will be further described below.

[0022] The device includes a valve body 1, which has a flow channel (not shown in the figure) for the medium to flow through. A ball (not shown in the figure) is placed inside the flow channel. A drive component (not shown in the figure) is provided on the valve body 1 to connect the ball. The drive component drives the ball to cut off the flow channel.

[0023] The valve body 1 is provided with an upper rotating part 2 and a lower rotating part 3, which are respectively located at the upper and lower ends of the ball. Both the upper rotating part 2 and the lower rotating part 3 include a rotating block 4 and a rotating frame 41. The rotating block 4 has a recessed connecting groove 42, and the ball has a protruding connecting part 43 that mates with the connecting groove 42. A rotating ball (not shown in the figure) is disposed within the rotating frame 41, rotatably positioned within the rotating frame 41, causing the rotating block 4 to be rotatably connected to the rotating frame 41. During assembly, the connecting part 43 of the ball is inserted into the connecting groove 42 of the rotating block 4, achieving circumferential fixation between the ball and the rotating block 4. When the ball rotates, the rotating block 4 rotates with the ball, and the rotating block 4 forms a rolling friction fit between the rotating ball and the rotating frame 41, significantly reducing frictional resistance.

[0024] A replacement port 5 is provided at the bottom of the valve body 1 for inserting and removing the ball. A rotating groove 51 is formed on the lower rotating part 3, and the rotating groove 51 is arc-shaped. A snap-fit ​​part 52 is formed on the valve body 1 at the replacement port 5. When installing the lower rotating part 3, align the rotating groove 51 of the lower rotating part 3 with the snap-fit ​​part 52, rotate the lower rotating part 3 so that it rotates along the arc-shaped rotating groove 51 and snaps into the replacement port 5, thus achieving the initial positioning of the lower rotating part 3. The valve body 1 is provided with a fixing member for fixing the upper rotating part 2 and the lower rotating part 3.

[0025] The end of the rotating groove 51 is connected to a fixing groove 44. The fixing component includes a fixing cover (not separately labeled in the figure), and a limiting groove that mates with the fixing cover is formed at the bottom of the valve body 1. A locking block 54 protrudes from the fixing cover and forms a limiting part 53. After the lower rotating part 3 rotates into position, the fixing cover is installed at the bottom of the valve body 1, so that the limiting part 53 is engaged with the limiting groove, and at the same time, the locking block 54 abuts against the fixing groove 44, restricting the circumferential rotation of the lower rotating part 3, thereby fixing the lower rotating part 3 inside the valve body 1.

[0026] A limiting groove 55 is formed on the upper rotating part 2, and a limiting protrusion (not shown in the figure) protrudes from the valve body 1 to cooperate with the limiting groove 55. When the upper rotating part 2 is installed in place, the limiting protrusion is engaged in the limiting groove 55 to circumferentially limit the upper rotating part 2, prevent it from rotating with the ball, and ensure that the upper rotating part 2 remains fixed in the valve body 1.

[0027] A control groove 61 is provided on the upper rotating part 2, and the driving component passes through the control groove 61 to connect with the ball. A cross groove 62 is formed on the connecting part 43 of the ball, and a plug-in part 63 protrudes from the driving component to mate with the cross groove 62. After the driving component passes through the control groove 61 of the upper rotating part 2, it is inserted into the cross groove 62 through the plug-in part 63, realizing the transmission connection between the driving component and the ball. At the same time, the control groove 61 guides and limits the driving component. The control groove 61 is filled with sealing packing 65, which can effectively prevent the medium inside the valve body 1 from leaking outward along the gap between the driving component and the control groove 61.

[0028] The assembly process of this embodiment is as follows: First, the upper rotating part 2 is inserted from above the valve body 1, aligning the limiting groove 55 with the limiting protrusion on the valve body 1 to complete the circumferential positioning of the upper rotating part 2. Then, the ball is inserted into the valve body 1 through the replacement port 5, so that the connecting part 43 at the upper end of the ball is inserted into the connecting groove 42 of the upper rotating part 2. Next, the lower rotating part 3 is inserted through the replacement port 5, aligning the rotating groove 51 with the snap-fit ​​part 52, and the lower rotating part 3 is rotated to snap into the replacement port 5, while the connecting part 43 at the lower end of the ball is inserted into the connecting groove 42 of the lower rotating part 3. Finally, the fixing cover is installed at the bottom of the valve body 1, so that the limiting part 53 snaps into the limiting groove and the locking block 54 abuts against the fixing groove 44 to complete the locking of the lower rotating part 3. The driving component is passed through the control groove 61, so that the insertion part 63 is inserted into the cross groove 62 of the ball, and the sealing filler 65 is filled into the control groove 61 to complete the assembly.

[0029] When disassembly is required, simply remove the fixing cover, rotate the lower rotating part 3 in the opposite direction to dislodge it from the replacement port 5, and the ball can be removed from the replacement port 5 without disassembling the valve body 1.

[0030] The above structure achieves rolling friction through a rotating ball, significantly reducing the operating torque during ball valve opening and closing. The combination of the replacement port, arc-shaped rotating groove, and fixed cover enables quick assembly and disassembly of the ball. The control groove and sealing packing ensure the sealing performance of the drive component. This embodiment features a compact structure, effortless operation, and convenient maintenance, making it particularly suitable for ball valve products requiring frequent maintenance or operation.
