[0002] A ball valve is a valve in which the valve stem drives the valve to rotate around the valve axis. It can be used for fluid regulation and control. An inlet pipe and an outlet pipe are installed on both sides of the valve body. During the use of a ball valve, the fluid medium often contains impurities. If it is not filtered, these impurities will clog the valve core as the fluid flows through the inlet pipe, making it difficult to open and close the ball valve and affecting its normal use.

[0003] Therefore, a new solution is needed to address this problem. Utility Model Content

[0007] Preferably, the clamping assembly includes a lead screw, two threaded blocks, and two clamping plates. The clamping plates are fixedly connected to the side of the threaded blocks near the filter plate and are used to abut against the filter plate. A fixed plate with an L-shaped cross-section is fixedly connected to the side of the connecting plate away from the liquid outlet pipe. The lead screw passes through the connecting plate and one end is rotatably mounted on the fixed plate. The lead screw includes a left-handed part and a right-handed part. The helix direction of the left-handed part is opposite to that of the helix direction of the right-handed part. The two threaded blocks are respectively threadedly connected to the left-handed part and the right-handed part.

[0008] Preferably, the clamping plate includes a horizontal part and a vertical part, the vertical part and the horizontal part are integrally formed, the threaded block is fixedly connected to the vertical part, and the filter plate is provided with a slot for the horizontal part to be engaged.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] Example:

[0019] A high-pressure resistant ball valve, such as Figures 1 to 4 As shown, the device includes a valve body 1 and an inlet pipe 2 and an outlet pipe 3 welded to both sides of the valve body 1. The inlet pipe 2 and the outlet pipe 3 are coaxially arranged. The valve body 1 is made of carbon steel. A filter plate 4 is slidably installed inside the inlet pipe 2. The filter plate 4 moves in a direction relatively perpendicular to the axial direction of the inlet pipe 2. An arc-shaped groove 5 communicating with the interior is opened on the outer peripheral wall of the inlet pipe 2, and a receiving frame 6 corresponding to the arc-shaped groove 5 is welded to the outer peripheral wall of the inlet pipe 2. The arc-shaped groove 5 and the receiving frame 6 are internally connected. One side of the receiving frame 6 is an arc-shaped concave surface and is welded to the outer peripheral wall of the inlet pipe 2. The top and bottom of the receiving frame 6 are open. The filter plate 4 is away from the outlet pipe 3. Multiple blades 8 are rotatably mounted on one side via a rotating assembly 7. An arc-shaped groove 5 is used for the filter plate 4, blades 8, and rotating assembly 7 to pass through. A cover plate 9 is provided on the filter plate 4 to close the top of the receiving frame 6. A connecting plate 10 is installed on the outer peripheral wall of the filter plate 4 near the arc-shaped groove 5. The connecting plate 10 is located inside the receiving frame 6 and the arc-shaped groove 5 respectively. The cover plate 9 is welded to the side of the connecting plate 10 away from the filter plate 4. The side of the connecting plate 10 near the filter plate 4 is an arc-shaped concave surface and fits against the outer peripheral wall of the filter plate 4. The rotating assembly 7 is installed on the side of the connecting plate 10 away from the liquid outlet pipe 3. A clamping assembly 11 for clamping the filter plate 4 is installed on the connecting plate 10.

[0020] The clamping assembly 11 includes a lead screw 111, two threaded blocks 112, and two clamping plates 113. The lead screw 111 passes through the two threaded blocks 112 respectively. The clamping plates 113 are welded to the side of the threaded blocks 112 near the filter plate 4 and are used to abut against the filter plate 4. A fixing plate 12 with an L-shaped cross-section is welded to the side of the connecting plate 10 away from the liquid outlet pipe 3. The lead screw 111 passes through the connecting plate 10 and one end is rotatably mounted on the fixing plate 12. The lead screw 111 includes a left-handed part 1111 and a right-handed part 1112. The helix of the left-handed part 1111... The direction of the spiral of the right-handed part 1112 is opposite to that of the spiral of the left-handed part 1111. The end of the lead screw 111 near the left-handed part 1111 is rotatably mounted on the fixed plate 12. Two threaded blocks 112 are threadedly connected to the left-handed part 1111 and the right-handed part 1112, respectively. The clamping plate 113 includes a horizontal part 1131 and a vertical part 1132. The vertical part 1132 and the horizontal part 1131 are integrally formed. The threaded blocks 112 are welded to the vertical part 1132. The filter plate 4 has two slots 13 for the horizontal part 1131 to be inserted.

[0021] The rotating assembly 7 includes a motor 701 and a rotating rod 702. The axis of the rotating rod 702 is perpendicular to the axis of the inlet pipe 2. A mounting plate 14 is welded to the side of the connecting plate 10 away from the outlet pipe 3. The motor 701 is mounted on the mounting plate 14 with screws, and the output end of the motor 701 passes through the mounting plate 14 and is welded to one end of the rotating rod 702. The blade 8 is welded to the outer peripheral wall of the rotating rod 702. A sealing gasket 15 for contacting the top of the receiving frame 6 is embedded and bonded to the cover plate 9. Fixing ears 16 are welded to the side walls of both the cover plate 9 and the receiving frame 6. The fixing ears 16 on the cover plate 9 and the receiving frame 6 are set one-to-one. The corresponding fixing ears 16 are fixedly installed by bolts. The bolts are wing bolts. The fixing ears 16 have threaded holes for connecting with the bolts.

[0022] As the fluid gradually flows through the inlet pipe 2 through the valve body 1, the motor 701, located inside the receiving frame 6, drives the rotating rod 702 to rotate. During the rotation of the rotating rod 702, multiple blades 8 rotate, which crushes larger impurities in the fluid, reducing the likelihood of blockage caused by larger impurities. The blades 8 do not contact the filter plate 4 during rotation. After the impurities are crushed by the rotating blades 8, they continue to flow until they adhere to the filter plate 4. At this time, the horizontal part 1131 is embedded in the slot 13, which can retain impurities and achieve a filtering effect. This reduces the likelihood of blockage caused by impurities as the fluid gradually flows through the inlet pipe 2 through the valve body 1. After filtration, the fluid continues to flow through the valve body 1 and the outlet pipe 3. The valve body 1 is made of carbon steel, which has high pressure resistance, thus improving the high pressure resistance of the valve body 1. The sealing gasket 15 on the cover plate 9 abuts against the top of the receiving frame 6, increasing the sealing between the cover plate 9 and the receiving frame 6.

[0023] When impurities adhere to both the filter plate 4 and the blade 8 and require cleaning, the rotation of the rotating rod 702 and the blade 8 is stopped by turning off the motor 701 until the axis of the blade 8 is perpendicular to the axis of the inlet pipe 2. Then, the bolts are tightened to disengage them from the threaded holes in the fixing ears 16 located in the cover plate 9 and the receiving frame 6, respectively. Afterward, the user pulls the cover plate 9, which moves the connecting plate 10, the clamping assembly 11, the rotating assembly 7, the filter plate 4, the blade 8, and the sealing gasket 15, so that the sealing gasket 15 is no longer in contact with the receiving frame 6. The tops abut against each other, allowing the filter plate 4 and blade 8 to pass sequentially through the arc-shaped groove 5 and the receiving frame 6. During movement, the filter plate 4 and blade 8 do not contact the inner walls of the arc-shaped groove 5 and the receiving frame 6, until the connecting plate 10, clamping assembly 11, rotating assembly 7, filter plate 4, and blade 8 are all disengaged from the inlet pipe 2. This facilitates the removal of the blade 8 and filter plate 4 from the inlet pipe 2, allowing for separate cleaning of the blade 8 and filter plate 4. When both the filter plate 4 and blade 8 are removed from the inlet pipe 2 and the filter plate 4 shows signs of damage... When the screw needs to be replaced, rotate the lead screw 111 clockwise. The lead screw 111 includes a left-handed portion 1111 and a right-handed portion 1112. The helix direction of the left-handed portion 1111 is opposite to that of the right-handed portion 1112. Two threaded blocks 112 are threaded onto the outer peripheral walls of the left-handed portion 1111 and the right-handed portion 1112, respectively. When the user holds the lead screw 111 close to one end of the right-handed portion 1112 and rotates it clockwise, the two threaded blocks 112 will then be engaged in the left-handed portion 1111 and the right-handed portion 1112, respectively. As part 1112 moves, the two threaded blocks 112 gradually move away from each other. When the threaded blocks 112 move, they drive the clamping plates 113 to move, so that the two clamping plates 113 move away from each other at the same time as the two threaded blocks 112 move away from each other. At this time, the horizontal part 1131 gradually disengages from the slot 13 until the horizontal parts 1131 of the two clamping plates 113 are both disengaged from the slots 13 on both sides of the filter plate 4, and the vertical part 1132 does not contact the filter plate 4. Then it is convenient to remove the filter plate 4 from the connecting plate 10 for replacement.

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.
