Description

Technical Field

[0001] This utility model relates to the technical field of ball valves, specifically to a straight-through self-locking ball valve. Background Technology

[0002] The straight-through ball valve adopts a straight flow channel, and the fluid does not change direction from the inlet to the outlet. The resistance coefficient is comparable to that of a pipe section of the same length, and the flow resistance is extremely small. At the same time, the straight-through ball valve is a sub-type of ordinary ball valve that focuses on low flow resistance and fast opening and closing.

[0003] Ball valves generally do not have a self-locking mechanism, or the self-locking method is cumbersome. During use, the valve stem can be easily actuated due to operation or collision, causing the opening and closing parts to rotate and resulting in leakage. Furthermore, when the valve core is directly rotated by the valve shaft, the opening angle error is relatively large, making it difficult to control the flow rate of the ball valve. Summary of the Invention

[0004] The purpose of this invention is to provide a straight-through self-locking ball valve to solve the above-mentioned defects caused by the prior art.

[0005] A straight-through self-locking ball valve includes a valve body one, a control box, and an electromagnet plate. A valve body two is bolted to one side of the valve body one. A control mechanism is located on the top of the valve body one. The control mechanism adjusts the rotation angle of the ball core, thereby facilitating precise flow control and preventing excessive rotation speed from causing the ball core to open and resulting in uncontrollable flow. Flanges are provided on both sides of the valve body one and valve body two. A locking mechanism is provided inside the control box. The locking mechanism magnetically positions the top of the drive gear to prevent external personnel from pressing down the handle, which would cause the drive gear and driven gear to mesh and transmit power.

[0006] Preferably, the control mechanism includes a valve seat, a ball core, a drive gear, a driven gear, a valve stem, and an infusion through hole. The valve seat is installed directly above the valve body. The valve stem is disposed inside the valve seat. The bottom end of the valve stem is connected to the ball core. An infusion through hole is formed on the outer side of the ball core. The top end of the valve stem is connected to the driven gear. A driven gear is disposed on one side of the drive gear. The driven gear is disposed inside the control box. The bottom end of the handle is connected to the top end of the drive gear.

[0007] Preferably, the ball core is connected to the outside of the drive gear via a valve stem located at its top.

[0008] Preferably, the locking mechanism includes a control box, a cover plate, a handle, a spring post, and an electromagnet. The control box is installed directly above the valve seat, and a cover plate is provided directly above the control box. A handle is connected through the outer side of the cover plate. The bottom end of the handle is connected to the top end of the spring post, and the bottom end of the spring post is connected to the outer side of the cover plate. An electromagnet is connected to the internal wires of the control box, and the electromagnet is positioned directly above the drive gear.

[0009] Preferably, the handle engages with the outer side of the driven gear via a driving gear located at its bottom end.

[0010] Preferably, the control box is fitted with the outer side of the drive gear via an internally installed electromagnet.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] 1. By controlling the gear ratio of the drive gear and the driven gear, when the gear ratio is 2:1, the output shaft speed is reduced by 50% and the torque is increased by about 1 time. The gear set can further amplify the adjustment precision, realize the micron-level displacement control of the valve core, and thus accurately control the opening angle of the ball core. At the same time, by pressing down the handle, the drive gear and the driven gear are connected and meshed, thus preventing accidental contact by outsiders. The drive gear directly drives the driven gear and valve stem for selection.

[0013] 2. When the valve stem is controlled, the handle is moved vertically upward by the spring column, so that the driving gear and the driven gear are vertically separated. At the same time, the electromagnet is used to magnetically attract the outside of the driving gear, thereby preventing outsiders from pressing down on the driving gear and accidentally touching the ball core. The spring column is also used to lift the handle, increasing the difficulty of pressing down and connecting. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 5 As shown, a straight-through self-locking ball valve includes a valve body 1, a control box 6, and an electromagnet 16. A valve body 2 is bolted to one side of the valve body 1. A control mechanism 3 is provided on the top of the valve body 1. The control mechanism 3 adjusts the rotation angle of the ball core 10, thereby facilitating precise flow control and preventing excessive rotation speed from causing the ball core 10 to open with an uncontrollable flow. Flanges 4 are provided on both sides of the valve body 1 and the valve body 2. A locking mechanism 9 is provided inside the control box 6. The locking mechanism 9 magnetically positions the top of the drive gear 12 to prevent external personnel from pressing down the handle 8, causing the drive gear 12 to mesh with the driven gear 13.

[0023] In this embodiment, the control mechanism 3 includes a valve seat 5, a ball core 10, a drive gear 12, a driven gear 13, a valve stem 14, and an infusion through hole 15. The valve seat 5 is installed directly above the valve body 1. The valve stem 14 is disposed inside the valve seat 5. The bottom end of the valve stem 14 is connected to the ball core 10. The infusion through hole 15 is opened through the outer side of the ball core 10. The top end of the valve stem 14 is connected to the driven gear 13. The driven gear 13 is disposed on one side of the drive gear 12. The driven gear 13 is disposed inside the control box 6. The bottom end of the handle 8 is connected to the top end of the drive gear 12.

[0024] In this embodiment, the ball core 10 is connected to the outside of the driven gear 13 via the valve stem 14 at the top. The driven gear 13 drives the ball core 10 to rotate, thereby precisely controlling the opening angle.

[0025] In this embodiment, the locking mechanism 9 includes a control box 6, a cover plate 7, a handle 8, a spring column 11, and an electromagnet plate 16. The control box 6 is installed directly above the valve seat 5. The cover plate 7 is located directly above the control box 6. The handle 8 is connected through the outer side of the cover plate 7. The bottom end of the handle 8 is connected to the top end of the spring column 11. The bottom end of the spring column 11 is connected to the outer side of the cover plate 7. The electromagnet plate 16 is connected to the internal wires of the control box 6. The electromagnet plate 16 is located directly above the drive gear 12. The cover plate 7 de-energizes the electromagnet plate 16 to control the drive gear 12.

[0026] In this embodiment, the handle 8 is connected to the outer side of the driven gear 13 via the driving gear 12 at its bottom end. The rotation speed is controlled by the engagement of the driving gear 12 and the driven gear 13.

[0027] In this embodiment, the control box 6 is attached to the outside of the drive gear 12 by an electromagnet plate 16 installed inside it, and the drive gear 12 is magnetically attracted by the electromagnet plate 16 to prevent the drive gear 12 from shaking.

[0028] In practical applications, this type of straight-through self-locking ball valve includes the following functions:

[0029] Step 1: Before assembly, first insert the spring post 11 through the outside of the handle 8, so that the bottom end of the spring post 11 contacts the cover plate 7 set at the top of the control box 6. At the same time, use the outside of the handle 8 to connect with the drive gear 12 by key, so that the electromagnet plate 16 is installed at the bottom of the cover plate 7, so that the electromagnet plate 16 contacts the surface of the drive gear 12. By opening the electromagnet plate 16, the drive gear 12 is magnetically attracted, so as to prevent outsiders from pressing down the handle 8 and causing the drive gear 12 to move down.

[0030] Step 2: During use, the flanges 4 on both sides are connected to the corresponding pipes. Then, the liquid is injected into the sealed chamber formed by the connection of valve body 1 and valve body 2. The liquid is blocked by the ball core 10 inside valve body 1. When it is necessary to open the ball core 10, the electromagnet 16 is closed, so that the electromagnet 16 loses its ability to magnetically attract the surface of the drive gear 12.

[0031] Step 3: The operator then presses down the handle 8, causing the spring column 11 at the bottom of the handle 8 to deform. This causes the drive gear 12 at the bottom of the handle 8 to mesh with the outer side of the driven gear 13. The drive gear 12 then drives the driven gear 13 to rotate, which in turn drives the ball core 10 to rotate. This causes the outer side of the ball core 10 to rotate through the infusion through hole 15, thus controlling the opening surface of the infusion through hole 15.

[0032] Step 4: After the infusion through-hole 15 is opened through the outer side of the ball core 10 to meet the flow delivery requirements, the handle 8 is released, so that the spring column 11 pushes the bottom end of the handle 8 to reset, so that the meshing state of the drive gear 12 and the driven gear 13 is separated, and then the drive gear 12 is put into contact with the electromagnet plate 16. Then the power supply of the electromagnet plate 16 is turned on to magnetically position the drive gear 12.

[0033] Therefore, the above-disclosed embodiments are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
