Description

Technical Field

[0001] The utility model relates to the technical field of gas safety valves, and specifically, to a novel gas safety valve. Background Art

[0002] Gas safety valves are applied in many fields such as industrial production, petrochemical industry, natural gas transportation, pharmaceuticals, and food. Gas safety valves undertake the important task of controlling the pressure not to exceed the specified value, and play a crucial role in protecting personal safety, preventing equipment damage, and ensuring the smooth progress of the production process. A gas safety valve includes a gas ball valve, and the gas ball valve mainly consists of a valve body, a valve stem, a ball, etc. The ball is a key component of the gas ball valve, and the opening and closing control of the gas pipeline is realized by rotation. The gas ball valve is widely used in various industrial fields and civil fields. In industries such as coal chemical industry, petrochemical industry, rubber, paper making, and pharmaceuticals, the gas ball valve is used as a device for medium shunting, confluence, or flow direction switching. In the civil field, the gas ball valve is mainly used for the opening and closing control of household gas pipelines.

[0003] There are some drawbacks in the existing devices during use. For example, during the use of the existing gas safety valve, if an operator accidentally touches the handle, the handle will be pushed and rotated. When the ball core moves due to the accidental rotation of the handle, the state of the gas pipeline will change. If the ball core moves from the closed state to the open state, it will lead to the risk of gas leakage. Gas leakage not only wastes resources, but may also cause serious accidents such as fires and explosions. Similarly, if the ball core moves from the open state to the closed state, it may interrupt the normal supply of gas and affect the normal use of users. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a novel gas safety valve, which solves the problem that the handle of the gas safety valve is pushed and rotated when an operator accidentally touches it during use.

[0005] The utility model provides the following technical solution: a novel gas safety valve, including a valve body. A valve ball is arranged inside the valve body. A connecting groove is formed on the outer wall of one side of the valve ball. A rotating rod is arranged inside the connecting groove. The rotating rod is fixedly connected to the valve ball through the connecting groove. One end of the rotating rod away from the valve ball vertically penetrates through the outer wall of one side of the valve body and is rotatably connected to the valve body. An annular fixing column is rotatably sleeved on the outer side of the rotating rod. The bottom end of the annular fixing column is fixedly connected to the outer wall of one side of the valve body. A sealing component is arranged on the rotating rod. The top end of the rotating rod is fixedly connected to a handle, and a locking component is arranged on the handle.

[0006] In the above solution, the valve ball is fixedly connected to the rotating rod through the connecting groove, so that the handle drives the rotating rod to drive the valve ball to rotate, realizing the control of gas flow. This design ensures the flexibility and accuracy of valve opening and closing. The sealing component prevents leakage during valve use. When the valve is in the open or closed state, the locking component locks it in that position to prevent valve movement caused by external factors.

[0007] As an optimization of the above technical solution, the sealing component includes two sealing grooves annularly formed on the outer side of the rotating rod. The two sealing grooves are arranged vertically, and sealing rings are respectively sleeved on the two sealing grooves.

[0008] In the above solution, the double-sealing effect is achieved through two vertically arranged sealing grooves and corresponding sealing rings. This design can significantly improve the sealing performance and reduce the leakage risk.

[0009] As an optimization of the above technical solution, the locking component includes a sliding groove formed on the handle. A sliding rod is slidably connected to the inner side of the sliding groove. The top end of the sliding rod is fixedly connected to a sliding button, and the bottom end of the sliding rod is fixedly connected to a limiting block. A toothed portion is fixedly sleeved on the outer side of the top of the annular fixed column. The limiting block is used in cooperation with the toothed portion. The bottom end of the handle is fixedly connected to a U-shaped mounting block. Mounting columns are respectively fixedly connected to the opposite inner side walls of the limiting block and the U-shaped mounting block. Springs are sleeved on the outer sides of the two mounting columns.

[0010] In the above solution, by pushing the sliding button to drive the sliding rod to move in the sliding groove, the limiting block is further moved to disengage from the toothed portion. When the limiting block disengages from the toothed portion, rotate the handle to drive the rotating rod and the valve ball to rotate to open the valve. When the valve reaches the required opening position or is fully opened, release the sliding button, and the compression force of the spring is released, pushing the sliding rod and the sliding button to move, so that the limiting block contacts the toothed portion again, locking the handle in the current position. When the valve needs to be closed, push the sliding button again to separate the limiting block from the toothed portion, and rotate the handle in the reverse direction to drive the rotating rod and the valve ball to rotate to close the valve. When the handle rotates to the closed position, release the sliding button, and the compression force of the spring pushes the sliding rod and the sliding button to move, so that the limiting block is fully engaged with the toothed portion, locking the closed state of the valve.

[0011] As an optimization of the above technical solution, the two ends of the spring are respectively fixedly connected to the opposite inner side walls of the corresponding limiting block and the U-shaped mounting block.

[0012] In the above solution, since the two ends of the spring are fixedly connected, the spring is more stable during operation. The tension of the spring can ensure that the limiting block contacts the toothed portion accurately and reliably, thereby ensuring that the valve can be stably maintained at the required position.

[0013] As a preference of the above technical solution, transverse chutes are respectively arranged on the opposite inner walls of the U-shaped mounting blocks, sliding blocks adapted to the sizes of the chutes are respectively fixedly connected to the opposite outer walls of the limit blocks, and the limit blocks are slidably connected to the U-shaped mounting blocks through the sliding blocks.

[0014] In the above solution, the chutes provide stable guidance for the sliding of the limit blocks, ensuring the stability and accuracy of the limit blocks during movement.

[0015] As a preference of the above technical solution, flange plates are respectively fixedly sleeved on the outer sides of both ends of the valve body.

[0016] In the above solution, the design of the flange plates makes the connection between the valve body and other pipelines or devices closer. Through bolt fastening, a tight seal can be achieved, effectively preventing gas leakage.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] In the present utility model, through the contact and separation mechanism between the limit block and the teeth, the valve can be reliably locked during the opening or closing process, which avoids accidental opening and closing of the valve caused by misoperation of the operator or external interference, thus significantly improving the safety of valve operation. After the compression force of the spring is released, it can automatically push the sliding rod and the sliding button to move, making the limit block contact the teeth again, realizing the automatic locking of the handle. This automatic locking function ensures that the valve can stably stay in that position after reaching the required position, further enhancing the safety of the valve.

Detailed implementation

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] Embodiment 1

[0027] As Figures 1-3 shown, the present invention provides a technical solution: a new type of gas safety valve, including a valve body 10, a valve ball 11 is arranged inside the valve body 10, a connection groove 12 is opened on the outer wall of one side of the valve ball 11, a rotating rod 13 is arranged inside the connection groove 12, the rotating rod 13 is fixedly connected with the valve ball 11 through the connection groove 12, the end of the rotating rod 13 away from the valve ball 11 vertically penetrates the outer wall of one side of the valve body 10 and is rotatably connected with the valve body 10, an annular fixing column 14 is rotatably sleeved outside the rotating rod 13, the bottom end of the annular fixing column 14 is fixedly connected to the outer wall of one side of the valve body 10, a sealing component is arranged on the rotating rod 13, the top end of the rotating rod 13 is fixedly connected with a handle 15, and a locking component is arranged on the handle 15. In the specific use process, the valve ball 11 is fixedly connected with the rotating rod 13 through the connection groove 12, so that the handle 15 drives the rotating rod 13 to drive the valve ball 11 to rotate, realizing the control of gas flow. This design ensures the flexibility and accuracy of valve opening and closing. The sealing component prevents leakage during valve use. When the valve is in the open or closed state, the locking component locks it in this position to prevent valve movement caused by external factors.

[0028] As an implementation method in this embodiment, as Figure 3 shown, the sealing component includes two sealing grooves 20 annularly opened on the outer side of the rotating rod 13, the two sealing grooves 20 are arranged up and down, and two sealing rings 21 are respectively sleeved in the two sealing grooves 20. In the specific use process, through the two sealing grooves 20 arranged up and down and the corresponding sealing rings 21, the effect of double sealing is realized. This design can significantly improve the sealing performance and reduce the leakage risk.

[0029] As an implementation method in this embodiment, as Figure 4 and Figure 5As shown in the figure, the locking component includes a sliding groove 30 formed in the handle 15. A sliding rod 31 is slidably connected to the inner side of the sliding groove 30. The top end of the sliding rod 31 is fixedly connected to a sliding button 32, and the bottom end of the sliding rod 31 is fixedly connected to a limiting block 33. A toothed part 34 is fixedly sleeved on the outer side of the top of the annular fixing column 14. The limiting block 33 is used in cooperation with the toothed part 34. The bottom end of the handle 15 is fixedly connected to a U-shaped mounting block 35. Mounting columns 36 are respectively fixedly connected to the opposite inner side walls of the limiting block 33 and the U-shaped mounting block 35. A spring 37 is sleeved on the outer sides of the two mounting columns 36. In the specific use process, by pushing the sliding button 32, the sliding rod 31 is driven to move in the sliding groove 30, so that the limiting block 33 moves away from the contact with the toothed part 34. When the limiting block 33 is separated from the contact with the toothed part 34, the handle 15 is rotated to drive the rotating rod 13 and the valve ball 11 to rotate to open the valve. When the valve reaches the required opening position or is fully opened, the sliding button 32 is released, and the compression force of the spring 37 is released, pushing the sliding rod 31 and the sliding button 32 to move, so that the limiting block 33 contacts the toothed part 34 again, locking the handle 15 in the current position. When it is necessary to close the valve, the sliding button 32 is pushed again to separate the limiting block 33 from the toothed part 34, and the handle 15 is rotated in the reverse direction to drive the rotating rod 13 and the valve ball 11 to rotate to close the valve. When the handle 15 is rotated to the closed position, the sliding button 32 is released, and the compression force of the spring 37 pushes the sliding rod 31 and the sliding button 32 to move, so that the limiting block 33 is fully engaged with the toothed part 34, locking the closed state of the valve.

[0030] As an implementation manner in this embodiment, as Figure 4 and Figure 5 shown, the two ends of the spring 37 are respectively fixedly connected to the opposite inner side walls of the corresponding limiting block 33 and the U-shaped mounting block 35. In the specific use process, since the two ends of the spring 37 are fixedly connected, the spring 37 is more stable during the working process. The tension of the spring 37 can ensure that the limiting block 33 contacts the toothed part 34 accurately and reliably, so as to ensure that the valve can be stably maintained at the required position.

[0031] As an implementation manner in this embodiment, as Figure 4 and Figure 5 shown, the opposite inner walls of the U-shaped mounting block 35 are respectively provided with transverse sliding grooves 40. The opposite outer walls of the limiting block 33 are respectively fixedly connected with sliding blocks 41 adapted to the size of the sliding grooves 40. The limiting block 33 is slidably connected to the U-shaped mounting block 35 through the sliding blocks 41. In the specific use process, the sliding grooves 40 provide stable guidance for the sliding of the limiting block 33, ensuring the stability and accuracy of the limiting block 33 during the movement.

[0032] As an implementation manner in this embodiment, as Figure 1 and Figure 2As shown, flange plates 50 are fixedly sleeved on the outer sides of both ends of the valve body 10. In the specific use process, the design of the flange plates 50 makes the connection between the valve body 10 and other pipelines or devices closer. Through bolt fastening, a tight seal can be achieved, effectively preventing gas leakage.

[0033] Working principle: Push the sliding button 32 to drive the sliding rod 31 to move in the sliding groove 30, so that the limiting block 33 disengages from the engagement with the ratchet teeth 34. Rotate the handle 15. The handle 15 is fixedly connected to the rotating rod 13 through the connecting groove 12, thereby driving the rotating rod 13 and the valve ball 11 to rotate. As the valve ball 11 rotates, the gas passage gradually opens to allow gas to pass through. When the valve reaches the required opening position or is fully opened, release the sliding button 32. The compression force of the spring 37 is released, pushing the sliding rod 31 and the sliding button 32 to reset, so that the limiting block 33 contacts the ratchet teeth 34 again, locking the handle 15 in the current position to prevent the valve from closing accidentally. When it is necessary to close the valve, push the sliding button 32 again to drive the sliding rod 31 to move, so that the limiting block 33 disengages from the engagement with the ratchet teeth 34. Rotate the handle 15 in the reverse direction to drive the rotating rod 13 and the valve ball 11 to rotate to close the gas passage. When the handle 15 rotates to the closed position, release the sliding button 32. The compression force of the spring 37 pushes the sliding rod 31 and the sliding button 32 to move, so that the limiting block 33 is fully engaged with the ratchet teeth 34, locking the closed state of the valve.

[0034] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
