Description

Technical Field

[0001] This utility model relates to the field of sealing equipment technology, and in particular to a sealing component with a compensation function. Background Technology

[0002] A ball valve is a valve in which the opening and closing element (ball) is driven by the valve stem and rotates around the valve's axis. It can also be used for fluid regulation and control. Ball valves are classified according to their actuation method: pneumatic ball valves, electric ball valves, and manual ball valves.

[0003] When a ball valve is in use, the valve core and valve body inside the ball valve are tightly fitted together to ensure sealing. Therefore, friction will occur between the valve core and valve body during the opening and closing of the ball valve. After long-term use, the valve core and valve body will wear due to long-term friction, which will lead to a decrease in sealing effect. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a sealing component with a compensation function.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a sealing component with a compensation function, comprising a hollow valve body, a valve core rotatably disposed within the valve body, a guide rod fixedly disposed on the upper surface of the valve body, a water passage hole penetrating the outer wall of the valve core, a rotating groove penetrating the upper surface of the guide rod, the rotating groove penetrating the valve body and communicating with the interior of the valve body, a rotating rod rotatably disposed within the rotating groove, the rotating rod being fixed to the upper end of the valve core, and a control component for controlling the up-and-down movement of the valve core disposed within the guide rod.

[0006] By adopting the above technical solution, when the operator needs to open the ball valve, they need to rotate the rotating rod, which in turn rotates the valve core under the action of the rotating rod, so that the water passage hole is aligned with the hole in the valve body, allowing water to flow from one end of the valve body to the other through the water passage hole. Subsequently, when the operator needs to close the ball valve, they need to rotate the rotating rod in the opposite direction, which in turn rotates the valve core under the action of the rotating rod, thereby closing the water passage hole and closing the ball valve. When the operator rotates the rotating rod, the control component can control the rotating rod to move upward, thereby reducing the probability of friction between the valve core and the valve body, thus reducing the probability of wear on the valve core and valve body, and thus improving the sealing performance of the device.

[0007] Furthermore, a sliding groove is formed through the outer wall of the rotating rod, and an arc-shaped groove is formed through the inner bottom wall of the sliding groove. An installation groove is formed on the inner wall of the valve body. The control component includes a limiting rod slidably disposed in the sliding groove and a compensating component installed in the installation groove. The limiting rod is rotatably connected to the arc-shaped groove. The limiting rod passes through the guide rod and is fixed to the guide rod. The compensating component is a compensating component made of rubber.

[0008] By adopting the above technical solution, when the operator rotates the rotating rod, the operator needs to slide the rotating rod upwards, causing the sliding groove and the limiting rod to slide relative to each other. Subsequently, when the limiting rod is aligned with the arc-shaped groove, the operator rotates the rotating rod, thereby driving the valve core to rotate. In this process, the valve core moves first and then rotates, thus reducing the probability of friction between the valve core and the valve body, thereby reducing the probability of wear on the valve core and valve body, and improving the sealing performance of the device. In addition, the compensating component reduces the probability of water leakage when the valve core moves, thereby further improving the sealing performance of the device.

[0009] Furthermore, an annular groove is formed on the inner wall of the rotating groove, and an annular block is rotatably arranged in the annular groove. The annular block is fixed to the rotating rod. A limiting spring is sleeved on the outer wall of the rotating rod. The lower end of the limiting spring abuts against the upper part of the annular block, and the upper end of the limiting spring abuts against the inner top wall of the annular groove.

[0010] By adopting the above technical solution, when the operator moves and rotates the rotating rod, the annular block moves and rotates in the annular groove under the action of the rotating rod. During this process, the limiting spring controls the limiting rod to abut against the inner top wall of the slide groove, thereby reducing the probability of the valve core moving due to external force during use, thus improving the stability of the device.

[0011] Furthermore, a sealing groove is provided on the inner wall of the rotating groove, and a sealing ring is installed in the sealing groove. The sealing ring is made of rubber.

[0012] By adopting the above technical solution, the sealing ring reduces the probability of water flowing into the rotating groove, thereby improving the sealing performance of the device.

[0013] Furthermore, a limiting groove is formed on the inner wall of the arc-shaped groove, and the limiting groove matches the limiting rod.

[0014] By adopting the above technical solution, when the operator opens the ball valve, the limiting rod is aligned with the limiting groove. At this time, the rotating rod slides under the action of the limiting spring, thereby causing the rotating rod to slide into the limiting groove. This reduces the probability of the rotating rod rotating due to external force during use, thus improving the stability of the device.

[0015] Furthermore, connecting plates are fixedly installed at both ends of the valve body, and multiple fixing holes are provided through the side wall of the connecting plates.

[0016] By adopting the above technical solution, the connecting plate and fixing hole reduce the difficulty for workers to connect the ball valve, thereby reducing the difficulty of their work.

[0017] Furthermore, a rotating handwheel is fitted on the outer wall of the rotating rod, and the rotating handwheel is fixed to the rotating rod.

[0018] By adopting the above technical solution, rotating the handwheel reduces the difficulty for workers to turn the rotating rod, thereby reducing the difficulty of their work.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. In this application, when an operator needs to open the ball valve, the operator needs to rotate the rotating rod, which causes the valve core to rotate under the action of the rotating rod, so that the water passage hole is aligned with the hole in the valve body, allowing water to flow from one end of the valve body to the other through the water passage hole. Subsequently, when the operator needs to close the ball valve, the operator needs to rotate the rotating rod in the opposite direction, which causes the valve core to rotate under the action of the rotating rod, thereby closing the water passage hole and closing the ball valve. When the operator rotates the rotating rod, the control component can control the rotating rod to move upward, thereby reducing the probability of friction between the valve core and the valve body, thus reducing the probability of wear on the valve core and valve body, and thus improving the sealing performance of the device.

[0021] 2. In this application, when the operator rotates the rotating rod, the operator needs to slide the rotating rod upwards, causing the sliding groove and the limiting rod to slide relative to each other. Subsequently, when the limiting rod is aligned with the arc-shaped groove, the operator rotates the rotating rod, thereby driving the valve core to rotate. In this process, the valve core is moved first and then rotated, which reduces the probability of friction between the valve core and the valve body, thereby reducing the probability of wear on the valve core and valve body, and thus improving the sealing performance of the device. In addition, the compensating component reduces the probability of water leakage when the valve core moves, thereby further improving the sealing performance of the device.

[0022] 3. In this application, when the operator moves and rotates the rotating rod, the annular block moves and rotates in the annular groove under the action of the rotating rod. During this process, the limiting spring controls the limiting rod to abut against the inner top wall of the slide groove, thereby reducing the probability of the valve core moving due to external force during use, thus improving the stability of the device.

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] like Figure 1-4 As shown in the figure, this application discloses a sealing assembly with a compensation function, including a valve body 1, a valve core 11, a guide rod 12, a rotating rod 15, a control assembly 3, an annular block 41, and a limiting spring 42. The valve core 11 is rotatably disposed inside the valve body 1, and a water passage hole 13 is formed through the outer wall of the valve core 11. The guide rod 12 is fixedly disposed on the upper surface of the valve body 1, with its axis vertical. A rotating groove 14 is formed through the upper surface of the guide rod 12, and the rotating groove 14 penetrates the valve body 1 and communicates with the interior of the valve body 1. The rotating rod 15 is a round rod structure, and its axis coincides with the axis of the guide rod 12. The rotating rod 15 is rotatably disposed in the rotating groove 14, and the rotating rod 15 is fixed to the upper end of the valve core 11.

[0030] When the operator needs to open the ball valve, they need to rotate the rotating rod 15, which in turn rotates the valve core 11 under the action of the rotating rod 15. This aligns the water passage 13 with the hole in the valve body 1, allowing water to flow from one end of the valve body 1 to the other through the water passage 13. Subsequently, when the operator needs to close the ball valve, they need to rotate the rotating rod 15 in the opposite direction, which in turn rotates the valve core 11 under the action of the rotating rod 15. This closes the water passage 13, thereby closing the ball valve. When the operator rotates the rotating rod 15, the control component 3 can control the rotating rod 15 to move upward, thereby reducing the probability of friction between the valve core 11 and the valve body 1, thus reducing the probability of wear on the valve core 11 and the valve body 1, and improving the sealing performance of the device.

[0031] A groove 2 is formed through the outer wall of the rotating rod 15, and an arc-shaped groove 21 is formed through the inner bottom wall of the groove 2. An installation groove 22 is formed on the inner wall of the valve body 1. A control component 3 is disposed within the guide rod 12 and is used to control the up-and-down movement of the valve core 11. The control component 3 includes a limiting rod 31 and a compensating member 32. The limiting rod 31 is a round rod with a horizontal axis. The limiting rod 31 is slidably disposed within the groove 2 and rotatably connected to the arc-shaped groove 21. The limiting rod 31 passes through the guide rod 12 and is fixed to the guide rod 12. The compensating member 32 is installed within the installation groove 22 and is made of rubber.

[0032] When the operator rotates the rotating rod 15, they need to slide the rotating rod 15 upwards, causing the slide groove 2 and the limiting rod 31 to slide relative to each other. Then, when the limiting rod 31 is aligned with the arc-shaped groove 21, the operator rotates the rotating rod 15, causing the valve core 11 to rotate. During this process, the valve core 11 is moved first and then rotated, thus reducing the probability of friction between the valve core 11 and the valve body 1, thereby reducing the probability of wear on both the valve core 11 and the valve body 1, and improving the sealing performance of the device. Furthermore, the compensating component 32 reduces the probability of water leakage when the valve core 11 moves, further improving the sealing performance of the device.

[0033] An annular groove 4 is formed on the inner wall of the rotating groove 14. An annular block 41 is rotatably disposed in the annular groove 4, and its axis coincides with the axis of the rotating rod 15. The annular block 41 and the rotating rod 15 are fixed to each other. A limiting spring 42 is sleeved on the outer wall of the rotating rod 15. The lower end of the limiting spring 42 abuts against the upper part of the annular block 41, and the upper end of the limiting spring 42 abuts against the inner top wall of the annular groove 4.

[0034] When the operator moves and rotates the rotating rod 15, the annular block 41 moves and rotates in the annular groove 4 following the rotating rod 15. During this process, the limiting spring 42 controls the limiting rod 31 to abut against the inner top wall of the slide groove 2, thereby reducing the probability of the valve core 11 moving under external force during use, thus improving the stability of the device.

[0035] To improve the sealing performance of the device, a sealing groove 5 is provided on the inner wall of the rotating groove 14, and a sealing ring 51 made of rubber is installed in the sealing groove 5. The sealing ring 51 reduces the probability of water flowing into the rotating groove 14, thereby improving the sealing performance of the device.

[0036] To improve the stability of the device, a limiting groove 6 is formed on the inner wall of the arc-shaped groove 21, and the limiting groove 6 matches the limiting rod 31. When the operator opens the ball valve, the limiting rod 31 is aligned with the limiting groove 6. At this time, the rotating rod 15 slides under the action of the limiting spring 42, thereby causing the rotating rod 15 to slide into the limiting groove 6, thus reducing the probability of the rotating rod 15 rotating due to external force during use, and thus improving the stability of the device.

[0037] To reduce the difficulty of the work for operators, connecting plates 7 are fixedly installed at both ends of the valve body 1, and multiple fixing holes 71 are opened through the side wall of the connecting plates 7. The connecting plates 7 and the fixing holes 71 reduce the difficulty for operators to connect the ball valve, thereby reducing the difficulty of the work for operators.

[0038] To reduce the difficulty of the work for the staff, a rotating handwheel 8 is fitted on the outer wall of the rotating rod 15, and the rotating handwheel 8 is fixed to the rotating rod 15. The rotating handwheel 8 reduces the difficulty for the staff to rotate the rotating rod 15, thereby reducing the difficulty of the work for the staff.

[0039] The operating principle of a sealing component with compensation function in this embodiment is as follows: When the operator needs to open the ball valve, the operator needs to rotate the rotating rod 15, which causes the valve core 11 to rotate under the action of the rotating rod 15, so that the water passage hole 13 is aligned with the hole of the valve body 1, allowing water to flow from one end of the valve body 1 to the other end through the water passage hole 13. Subsequently, when the operator needs to close the ball valve, the operator needs to rotate the rotating rod 15 in the opposite direction, which causes the valve core 11 to rotate under the action of the rotating rod 15, thereby closing the water passage hole 13 and closing the ball valve. When the operator rotates the rotating rod 15, the control component 3 can control the rotating rod 15 to move upward, thereby reducing the probability of friction between the valve core 11 and the valve body 1, thus reducing the probability of wear between the valve core 11 and the valve body 1, and thus improving the sealing performance of the device.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
