[0031] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0032] In the present invention, unless otherwise stated, directional words such as "upper, lower, inside, outside" contained in a term merely represent the orientation of the term in normal usage, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0033] like Figure 1-7 As shown, a ball valve for a breaker hammer pipeline comprises: a ball valve body 1 and at least one set of filter units connected to the corresponding ends of the ball valve body 1, wherein the filter unit comprises a pipe body 2, a pair of first sealing covers 3 assembled on both ends of the pipe body 2, a filter element slidably arranged inside the pipe body 2, and an adjustment mechanism assembled on the pair of first sealing covers 3 for pushing the filter element to slide inside the pipe body 2, and a pair of connection ports 4 evenly distributed along the circumferential direction are arranged in the middle of the pipe body 2;

[0034] The filter element includes at least three spacer plates 5 whose outer walls are evenly fitted and in contact with the inner wall of the tube body 2 and are arranged at equal intervals along the axial direction of the tube body 2. A pair of arc plates 6 coaxially arranged with the spacer plates 5 and whose outer walls are in contact with the inner wall of the tube body 2 are arranged between two adjacent spacer plates 5. The two ends of each arc plate 6 are respectively fixedly connected to the two adjacent spacer plates 5. The connecting port 4 is located between the pair of arc plates 6. A group of filtering mechanisms fitted and connected to the inner walls of the arc plates 6 are arranged between two adjacent spacer plates 5.

[0035] In the above technical solution, during the continuous use of the filter mechanism, the impurities filtered and intercepted will gradually block the gaps on the filter mechanism, reducing the oil flow rate of the filter mechanism. At this time, the filter element can be pushed to slide in the tube body 2 through the adjustment mechanism, so that the other filter mechanism is moved to face the connection port 4. At this time, the filter unit can be used normally without the need to directly replace the internal filter element on site. It can be replaced in spare time later, thereby improving the replacement fault tolerance rate.

[0036] The two adjacent spacer disks 5 and the corresponding pair of arc-shaped plates 6 also form a slag storage space opening toward the connecting port 4. The impurities intercepted by the filtration will be located in the slag storage space. When the filter element is pushed to slide in the tube body 2 through the adjustment mechanism, the impurities located in the slag storage space will also be taken away. Because the two adjacent spacer disks 5 are staggered from the connecting port 4, the filtered impurities will not be mixed into the oil again, and the service life of the other filtering mechanism can also be extended.

[0037] In a preferred embodiment of the invention, the filtering mechanism includes a base plate 7 fixedly connected to two adjacent spacer disks 5 and a filter plate 9 assembled on the base plate 7 by a plurality of mounting bolts 8, a plurality of oil holes 10 are provided on the base plate 7, and the two side edges of the base plate 7 adjacent to the spacer disks 5 are respectively fitted and fixedly connected to the corresponding arc plates 6, and the base plate 7 is located in the middle of the two side edges of the arc plates 6.

[0038] In the above technical solution, the oil will pass through the filter plate 9 and the oil through hole 10 , while the impurities will be intercepted by the filter plate 9 .

[0039] In a preferred embodiment of the invention, the number of the spacer discs 5 is three, and at least two positioning grooves 11 are provided on one side of the spacer disc 5 located at the end close to the first sealing cover 3, and the adjustment mechanism includes at least two sealing bolts 12 assembled on the same first sealing cover 3 and at least two adjusting bolts 13 assembled on another first sealing cover 3, and the first sealing cover 3 is penetrated with a threaded through hole opposite to the positioning groove 11, and the end of the adjusting bolt 13 can be inserted into the corresponding positioning groove 11;

[0040] The heads of the sealing bolt 12 and the adjusting bolt 13 are tightly pressed against the corresponding first sealing end covers.

[0041] In the above technical solution, when it is necessary to push the filter element to slide in the tube body 2, the adjusting bolt 13 and the sealing bolt 12 are both removed, and the sealing bolt 12 is installed on the threaded through hole where the original adjusting bolt 13 is installed, and the adjusting bolt 13 is installed on the threaded through hole where the original sealing bolt 12 is installed. At this time, the adjusting bolt 13 will push the filter element to move in the tube body 2, so that the filter element contacts the first sealing cover 3 away from the adjusting bolt 13, and the end of the adjusting bolt 13 is inserted into the positioning groove 11 to prevent the filter element from rotating during normal use.

[0042] In a preferred embodiment of the present invention, the adjusting bolt 13 and the sealing bolt 12 are both sleeved with a first rubber ring 14 .

[0043] In the above technical solution, the first rubber ring 14 can improve the sealing performance between the sealing bolt 12 and the adjusting bolt 13 and the first sealing cover 3 .

[0044] In a preferred embodiment of the invention, a first threaded portion is provided on the inner wall of the end of the tube body 2, and an annular flange portion 15 is coaxially protruded from the inner wall of the end of the tube body 2 and is located near the connecting port 4 on the first threaded portion. The outer wall of the first sealing cover 3 is threadedly mounted on the first threaded portion, and a second rubber ring 16 is provided between the first sealing cover 3 and the annular flange portion 15.

[0045] In the above technical solution, the second rubber ring 16 can improve the sealing performance between the first sealing cover 3 and the annular flange portion 15 .

[0047] In the above technical solution, the second sealing cover 17 can further improve the sealing performance of the filter unit. The end of the tube body 2 has two sealing measures, the first sealing cover 3 and the second sealing cover 17. The third rubber ring 18 can improve the sealing performance between the second sealing cover 17 and the end of the tube body 2.

[0048] In a preferred embodiment of the present invention, a polygonal groove 19 is provided on a side of the first sealing cover 3 away from the filter element.

[0049] In the above technical solution, the polygonal groove 19 facilitates the insertion of a tool to tighten the first sealing cover 3 .

[0050] In a preferred embodiment of the invention, at least one coaxial annular groove is recessed on the side wall of the spacer disk 5 , and a sealing ring 20 that can fit in contact with the inner wall of the tube body 2 is arranged in the annular groove.

[0051] In the above technical solution, the sealing ring 20 is made of rubber material, which can improve the sliding sealing between the filter element and the inner wall of the tube body 2.
