Description

Technical Field

[0001] This utility model relates to the field of ball valve technology, specifically a ball valve with a positioning function. Background Technology

[0002] In existing ball valve technology, the flanges on both sides of the ball valve need to be bolted to the flanges of the pipes on both sides of the ball valve during actual use. Since the pipes are often at a certain height above the ground, the user needs to lift the ball valve to place it between the two pipes, which makes the installation process labor-intensive and inconvenient for the user.

[0003] According to a ball valve with positioning function disclosed in the public notice (publication number: CN221170846U), the above application includes a valve body and a control end. The control end is provided at the middle position of the top of the outer peripheral surface of the valve body. The valve body has symmetrically distributed connecting pipes on both sides. The bottom of the outer peripheral surface of the valve body is fixed with a support base. A movable shaft is rotatably connected through the middle position of the support base. The movable shaft has symmetrically distributed internal threaded holes on both sides of its inner cavity. The internal threads of the internal threaded holes are connected to threaded blocks.

[0004] However, in actual installation, the positioning device on the outside of the ball valve requires the user to first lift the ball valve between the pipes and align its flange with the pipe flange before the positioning device can function. In the lifted state, the ball valve needs to achieve precise alignment of its vertical height, horizontal position, and rotation angle simultaneously, which requires repeated adjustments and is inefficient. In view of this, we propose a ball valve with positioning function. Summary of the Invention

[0005] The purpose of this invention is to provide a ball valve with a positioning function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a ball valve with a positioning function, comprising a ball valve body, a pipe disposed on the side wall of the ball valve body, and a positioning component disposed on the outer wall of the ball valve body, the positioning component comprising:

[0007] A connecting frame 1, wherein a hinge rod is hinged to the side wall of the connecting frame 1, and a ratchet is fixedly connected to the side wall of the hinge rod;

[0008] A rotating rod, wherein a pawl is sleeved on the side wall of the rotating rod;

[0009] A limiting frame, which is fixedly connected to the side wall of the connecting frame one;

[0010] The second connecting frame has a rotating block rotatably connected to its side wall, and a baffle is fixedly connected to its side wall.

[0011] Preferably, a flange one is fixedly connected to the side wall of the ball valve body, and a flange two is fixedly connected to the end face of the pipe. The axes of flange one and flange two coincide, and flange one and flange two abut against each other.

[0012] Preferably, the connecting frame is disposed on the outer wall of the ball valve body, and the hinge rods are symmetrically disposed on the side walls of the connecting frame.

[0013] Preferably, the rotating rod is fixedly connected to the side wall of the connecting frame, and the pawl engages with the ratchet.

[0014] Preferably, the limiting frame is movably connected to the outer wall of the pawl, and the limiting frame is located below the pawl. The limiting frame restricts the rotation direction of the pawl, thereby allowing the ratchet and the hinge rod to rotate only in one direction.

[0015] Preferably, the connecting frame two is disposed on the outer wall of the pipe, the rotating block is sleeved with the hinge rod, the bottom of the baffle is movably connected to the hinge rod, and the baffle limits the hinge rod. When the axis of the ball valve body coincides with that of the pipe, the axes of the ball valve body, the pipe and the hinge rod are located in the same plane. At this time, the baffle prevents the hinge rod from continuing to rotate.

[0016] Preferably, the inner walls of the first connecting frame and the second connecting frame are fixedly connected to a slide rail, and the slide rail is inserted into the abutment frame.

[0017] Compared with the prior art, this utility model provides a ball valve with positioning function, which has the following beneficial effects:

[0018] 1. This ball valve with positioning function, through its positioning component, first connects the pipeline to the ball valve body, then raises the ball valve body to the appropriate position. After release, the pawl engages the ratchet, and the limit bracket prevents it from rotating, keeping the ball valve body suspended at the current height. This avoids the worker constantly lifting the valve, reducing manual labor. The worker can install the valve with their hands free while it is being supported, avoiding the clumsy operation of lifting and aligning simultaneously, thus improving alignment accuracy. The stop action of the baffle allows the ball valve body to automatically maintain axial alignment with the pipeline, eliminating the need to rely entirely on experience or visual inspection. The baffle provides physical limitation, preventing the ball valve body from deviating from the pipeline due to excessive rotation of the hinge rod during installation, preventing over-rotation or under-rotation that could cause alignment errors, ensuring accurate flange alignment, and ensuring precise positioning.

[0019] 2. This ball valve with positioning function can adapt to different diameters of pipelines and the outer wall of the ball valve body through the set abutment bracket, improving its versatility. The abutment bracket is in close contact with the pipeline and the outer wall of the ball valve body, which can stabilize the ball valve in the correct position, prevent the ball valve from shaking during lifting or installation, and improve the flange alignment accuracy.

[0026] like Figures 1-5 As shown, this utility model provides a technical solution: a ball valve with positioning function, including a ball valve body 1, a pipe 2 provided on the side wall of the ball valve body 1, a flange 1 fixedly connected to the side wall of the ball valve body 1, a flange 2 fixedly connected to the end face of the pipe 2, the axes of flange 1 and flange 2 coincide and abut against each other, and a positioning component 3 is provided on the outer wall of the ball valve body 1, the positioning component 3 including a connecting frame 1 301, a hinge rod 302, a ratchet 303, a rotating rod 304, a pawl 305, a limiting frame 306, a connecting frame 2 307, a rotating block 308, and a baffle 309.

[0027] In one embodiment of this utility model, a connecting frame 301 is disposed on the outer wall of the ball valve body 1, and a hinge rod 302 is hinged to the side wall of the connecting frame 301. The hinge rods 302 are symmetrically disposed on the side wall of the connecting frame 301, and a ratchet 303 is fixedly connected to the side wall of the hinge rod 302.

[0028] The rotating rod 304 is fixedly connected to the side wall of the connecting frame 301. A pawl 305 is sleeved on the side wall of the rotating rod 304, and the pawl 305 meshes with the ratchet 303.

[0029] The limiting frame 306 is fixedly connected to the side wall of the connecting frame 301. The limiting frame 306 is movably connected to the outer wall of the pawl 305. The limiting frame 306 is located below the pawl 305. The limiting frame 306 restricts the rotation direction of the pawl 305, thereby making the ratchet 303 and the hinge rod 302 rotate only in one direction.

[0030] The second connecting bracket 307 is installed on the outer wall of the pipe 2. A rotating block 308 is rotatably connected to the side wall of the second connecting bracket 307. The rotating block 308 is sleeved with the hinge rod 302. A baffle 309 is fixedly connected to the side wall of the second connecting bracket 307. The bottom of the baffle 309 is movably connected to the hinge rod 302. The baffle 309 limits the hinge rod 302. When the axis of the ball valve body 1 coincides with that of the pipe 2, the axes of the ball valve body 1, the pipe 2 and the hinge rod 302 are in the same plane. At this time, the baffle 309 prevents the hinge rod 302 from continuing to rotate.

[0031] Connector 1 301 is fitted onto ball valve body 1, connector 2 307 is fitted onto pipe 2, and hinge rod 302 is inserted into rotating block 308. First, pipe 2 is connected to ball valve body 1. Then, ball valve body 1 is lifted using lifting equipment or manually. At this time, hinge rod 302 rotates counterclockwise, ratchet 303 rotates to push pawl 305 away, releasing the lifting force on ball valve body 1. Limit bracket 306 restricts the reverse rotation of pawl 305, preventing hinge rod 302 and... With the clockwise rotation of the ratchet 303, the operator only needs to use lifting equipment or manpower to raise the ball valve body 1 to a suitable position in the initial stage. After releasing, the pawl 305 will lock the ratchet 303, and the limit bracket 306 will prevent it from rotating back, keeping the ball valve body 1 suspended at the current height. This avoids the worker having to lift it continuously, reducing the manual burden. The worker can use both hands to install the ball valve body 1 while it is being supported, avoiding the clumsy operation of lifting and aligning at the same time, and improving the alignment accuracy.

[0032] When the axis of the ball valve body 1 coincides with that of the pipe 2, the axes of the ball valve body 1, the pipe 2, and the hinge rod 302 are in the same plane. At this time, the baffle 309 prevents the hinge rod 302 from continuing to rotate. When the worker operates the hinge rod 302, the stopping action of the baffle 309 can automatically keep the axis of the ball valve body 1 and the pipe 2 aligned, without relying entirely on experience or visual inspection. The baffle 309 provides physical limit to prevent the ball valve body 1 from deviating from the pipe 2 due to excessive rotation of the hinge rod 302 during installation, and to prevent over-rotation or under-rotation from causing misalignment, ensuring accurate flange alignment and precise positioning.

[0033] In addition, the inner walls of connecting bracket 1 301 and connecting bracket 2 307 are fixedly connected to slide rail 4. The slide rail 4 is inserted into the abutment bracket 5. The abutment bracket 5 abuts against the outer wall of the pipe 2 and the ball valve body 1. After connecting bracket 1 301 is put on the ball valve body 1 and connecting bracket 2 307 is put on the pipe 2, by inserting abutment brackets 5 of different sizes in the slide rail 4, different diameters of the outer wall of the pipe 2 and the ball valve body 1 can be adapted, solving the problem that a single fixing device cannot be compatible with multiple specifications, improving versatility. The abutment bracket 5 is in close contact with the pipe 2 and the outer wall of the ball valve body 1, which can stabilize the ball valve in the correct position, prevent the ball valve from shaking during lifting or installation, and improve the flange alignment accuracy.

[0034] In this invention, during use, the hinge rod 302 is inserted into the rotating block 308, and the ball valve body 1 is lifted using a lifting device or by hand. At this time, the hinge rod 302 rotates counterclockwise, and the ratchet 303 rotates to push the pawl 305 away. After the lifting force on the ball valve body 1 is released, the limit bracket 306 restricts the reverse rotation of the pawl 305, preventing the hinge rod 302 and the ratchet 303 from rotating clockwise. After being released, the pawl 305 will lock the ratchet 303, and the limit bracket 306 will prevent it from rotating back, thus keeping the ball valve body 1 suspended at the current height. Workers can install the ball valve body 1 with their hands free while it is being supported, avoiding the clumsy operation of lifting and aligning at the same time, and improving the alignment accuracy. The stopping action of the baffle 309 allows the ball valve body 1 and the pipeline 2 to automatically maintain axial alignment, without relying entirely on experience or visual inspection, preventing over-rotation or under-rotation from causing alignment errors, and ensuring accurate flange alignment.

[0035] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
