Description

Technical Field

[0001] This utility model relates to the field of ball valve technology, and in particular to an anti-clogging ball valve. Background Technology

[0002] A ball valve is a type of valve that controls the flow of fluid by rotating a ball with a through hole. A ball valve consists of a valve body, a sealing ring, a ball, and a valve stem. When using a ball valve, the valve body is installed on the pipeline via a flange connection. Rotating the valve stem 90 degrees causes the ball to rotate, allowing water to flow out through the through hole in the ball. Rotating the valve stem 90 degrees again causes the ball to engage with the sealing ring, thus preventing water from flowing out.

[0003] In their daily work, the inventor discovered that when using ball valves, in order to prevent mud and sand in the water from affecting the ball valve, a filter pipe is usually added to the inlet end of the valve body. The filter pipe is equipped with a filter screen to filter the water. However, since the filter screen is fixedly connected inside the filter pipe, after a long period of filtration, some mud and sand with a pore size similar to the filter screen may get stuck in the filter screen pores, which will clog the filter screen and thus affect the water flow of the filter screen. Utility Model Content

The filter pipe is equipped with a filter screen to filter the water. However, since the filter screen is fixedly connected inside the filter pipe, after a long period of filtration, some mud and sand with a pore size similar to the filter screen may get stuck in the filter screen pores, thus clogging the filter screen and affecting the water flow of the filter screen. Therefore, an anti-clogging ball valve is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an anti-clogging ball valve, comprising a valve body, wherein a ball is disposed inside the valve body, and sealing rings are fixedly connected to both sides of the inner wall of the valve body.

An mounting plate is slidably connected to the inner wall of the grooved rotating rod. A brush bristle is fixedly connected to the left end of the mounting plate, and the brush bristle is flexible.

[0006] The effect achieved by the above components is as follows: by setting up the cleaning component, when preventing the filter screen from clogging, the grooved rotating rod is rotated by the drive mechanism, which causes the bristles on the mounting plate to rotate accordingly. The bristles penetrate the filter screen holes and poke out the stuck mud and sand particles, thereby achieving the effect of preventing the filter screen from clogging as much as possible.

[0007] Preferably, a first spring is fixedly connected to the right end of the mounting plate, and the other end of the first spring is fixed to the grooved rotating rod.

[0008] The effect achieved by the above components is as follows: by setting the first spring, when the brush bristles come into contact with the filter screen, the first spring is compressed, so that its directional force pushes the mounting plate, thereby making the brush bristles fully contact the filter screen.

[0009] Preferably, the inner wall of the filter tube is provided with a rotating ring rotatably connected by a first bearing, and the grooved rotating rod is fixed to the rotating ring.

[0010] The effect achieved by the above components is as follows: the rotating ring rotates, causing the grooved rotating rod to rotate; the outer ring of the first bearing is fixed to the rotating ring; and the inner ring of the first bearing is fixed to the filter tube.

[0011] Preferably, the arc surface of the filter tube is provided with a sprocket rotatably connected by a second bearing, and the sprocket is used to connect an external chain.

[0012] The effect achieved by the above components is as follows: the sprocket is connected to the external chain, the chain is driven by an external motor, which drives the sprocket to rotate, and the attraction mechanism drives the rotating ring to rotate. The inner ring of the second bearing is fixed to the filter tube, and the outer ring of the second bearing is fixed to the sprocket.

[0013] Preferably, a first magnetic sheet is fixedly connected to the inner arc surface of the sprocket, and a second magnetic sheet is fixedly connected to the arc surface of the rotating ring, with the first and second magnetic sheets attracting each other.

[0014] The effect achieved by the above components is as follows: by setting the first magnetic plate and the second magnetic plate, the sprocket rotates, which drives the rotating ring to rotate, and the filter tube can be a plastic tube.

[0015] Preferably, the arc surface of the filter tube is provided with a disassembly assembly, the disassembly assembly including a disassembly block inserted into the arc surface of the filter tube, and the surface of the disassembly block is provided with a sealing strip.

[0016] The effect achieved by the above components is that dragging the disassembly block separates it from the filter tube, thereby discharging the mud and sand accumulated on one side of the filter screen, allowing workers to periodically remove the mud and sand.

[0017] Preferably, the filter tube has fixed semicircular blocks on both sides of its arc surface, and the lower fixed semicircular block is fixed to the disassembly block.

[0018] The effect achieved by the above components is as follows: the disassembly block is inserted into the filter tube, then the upper fixing semicircular block is placed against the lower semicircular block, and then the fixing mechanism is used to fix it.

[0019] Preferably, the upper fixed semicircular block has screws inserted at both ends, and the lower fixed semicircular block has a nut that matches the screws at its lower end.

[0020] The effect achieved by the above components is to bring the upper fixed semicircular block against the lower semicircular block and fix it by screws and nuts.

[0021] In summary, the beneficial effects of this utility model are as follows:

[0022] In this invention, by setting up a cleaning component, when preventing the filter screen from clogging, the grooved rotating rod is rotated by a drive mechanism, causing the bristles on the mounting plate to rotate accordingly. The bristles penetrate the filter screen mesh and poke out the stuck mud and sand particles, thereby maximizing the effect of preventing the filter screen from clogging. This solves the problem that in order to avoid mud and sand in the water affecting the ball valve, a filter pipe is usually added to the inlet end of the valve body. The filter pipe is equipped with a filter screen to filter the water. However, since the filter screen is fixed inside the filter pipe, after a long period of filtration, some mud and sand with a diameter similar to that of the filter screen mesh may get stuck in the filter screen mesh, thus clogging the filter screen and affecting the water flow of the filter screen.

A mounting plate 22 is slidably connected to the inner wall of the grooved rotating rod 21. A brush bristle 23 is fixedly connected to the left end of the mounting plate 22. The brush bristle 23 is flexible. By setting the cleaning component 2, when preventing clogging of the filter screen 8, the grooved rotating rod 21 rotates via a drive mechanism, causing the brush bristle 23 on the mounting plate 22 to rotate accordingly. The brush bristle 23 inserts into the mesh of the filter screen 8, dislodging the stuck mud and sand particles, thereby maximizing the anti-clogging effect on the filter screen 8. A first spring 24 is fixedly connected to the right end of the mounting plate 22. The other end of the first spring 24 is fixed to the grooved rotating rod 21. By setting the first spring 24, when the brush bristle 23 contacts the filter screen 8, the first spring 24 is compressed, causing its directional force to push the mounting plate 22, thereby ensuring full contact between the brush bristle 23 and the filter screen 8. The inner wall of the filter tube 7 is provided with a rotatable connection via a first bearing 29. The rotating ring 25 has a grooved rotating rod 21 fixed to it. When the rotating ring 25 rotates, the grooved rotating rod 21 rotates.

[0031] Working principle:

[0032] When using the ball valve, the valve body 1 is installed on the pipeline via a flange connection. Rotating the valve stem 6 90 degrees causes the ball 4 to rotate, allowing water to flow through the through-hole of the ball 4. Rotating the valve stem 6 90 degrees again causes the ball 4 to engage with the sealing ring 5, preventing water from flowing out. To prevent clogging of the filter screen 8, the sprocket 26 is connected to an external chain driven by an external motor, causing the sprocket 26 to rotate. By setting the first magnetic plate 27 and the second magnetic plate 28, the rotation of the sprocket 26 causes the rotating ring 25 to rotate. The filter tube 7 can be a plastic tube. The inner ring of the second bearing 210 is fixed to the filter tube 7, and the outer ring of the second bearing 210 is fixed to the sprocket 26. The rotation of the rotating ring 25 causes the grooved rotating rod 21 to rotate. The outer ring of the first bearing 29 is connected to the rotating ring 25. Ring 25 is fixed, and the inner ring of the first bearing 29 is fixed to the filter tube 7, so that the bristles 23 on the mounting plate 22 rotate with it. The bristles 23 insert into the mesh of the filter screen 8 and poke out the stuck mud and sand particles, thereby achieving the effect of preventing the filter screen 8 from clogging as much as possible. By setting the first spring 24, when the bristles 23 come into contact with the filter screen 8, the first spring 24 is compressed, so that its directional force pushes the mounting plate 22, thereby making the bristles 23 fully contact the filter screen 8. Dragging the disassembly block 31 separates it from the filter tube 7, thereby discharging the mud and sand accumulated on one side of the filter screen 8. Workers can periodically discharge the mud and sand. The disassembly block 31 is inserted into the filter tube 7, and then the upper fixed semicircular block 32 is placed against the lower semicircular block, and then fixed by using the screw 33 and nut 34.
