[0021] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0022] Reference Figures 1 to 5The utility model embodiment is a filter ball valve, which includes a valve body 1: a valve ball 2 is arranged in the valve body 1, and a positioning block 3 is fixedly connected to the top of the valve body 1, a rotating block 4 is arranged above the positioning block 3, and a rotating rod 5 is fixedly connected to the bottom of the rotating block 4, and the bottom end of the rotating rod 5 passes through the positioning block 3 and the valve body 1, and is fixedly connected to the valve ball 2, flanges 6 are fixedly connected to both sides of the valve body 1, and a filter screen 7 is arranged in the valve body 1, and a vertical rod 8 is fixedly connected to the filter screen 7, a sealing block 9 passes through the side wall of the valve body 1, and a pair of first bolts 10 pass through the sealing block 9, a pair of threaded grooves matching the first bolts 10 are opened on the valve body 1, and a slag guide pipe 11 is fixedly connected to the bottom of the valve body 1, a slag blocking cover 12 is sleeved on the slag guide pipe 11, an internal thread is opened on the inner wall of the slag blocking cover 12, and an external thread matching the internal thread is opened on the outer wall of the slag guide pipe 11, and a slag outlet 13 is opened at the bottom of the valve body 1.

[0023] The force is evenly distributed, which improves the installation stability of the filter ball valve. A pair of flanges 6 are symmetrically arranged about the central axis of the valve body 1.

[0024] The force is evenly distributed, thereby improving the installation stability of the sealing block 9 , and a pair of first bolts 10 are symmetrically arranged about the central axis of the sealing block 9 .

[0025] The filter screen 7 is limited so as to improve the installation stability of the filter screen 7 , and a limiting block 14 is fixedly connected to the inner wall of the valve body 1 .

[0026] The rotating rod 5 is limited to improve the stability of the valve ball 2 in the closed state. A second bolt 15 passes through the positioning block 3. A positioning groove 16 matching the second bolt 15 is opened on the rotating rod 5. A rectangular ring 17 is fixedly connected to the side wall of the second bolt 15.

[0027] To improve the surface friction of the rectangular ring 17, anti-slip grooves are provided on the outer wall of the rectangular ring 17.

[0028] In order to improve the surface friction of the rotating block 4, anti-skid grooves are provided on the outer wall of the rotating block 4.

[0029] Working principle: When the utility model is used, the filter ball valve is installed on the pipeline through the flange 6. When the filter ball valve needs to be opened, the rectangular ring 17 is rotated, and the rectangular ring 17 drives the second bolt 15 away from the positioning groove 16. At this time, the rotating block 4 is rotated, and the rotating block 4 drives the valve ball 2 to rotate through the rotating rod 5 until the opening on the valve ball 2 is parallel to the inner cavity of the valve body 1. The fluid can pass through the valve body 1. During the fluid circulation process, impurities in the fluid are filtered through the filter screen 7, and the impurities are introduced into the slag guide pipe 11 through the slag outlet 13. When the filter screen 7 needs to be replaced, the first bolt 10 is unscrewed, the sealing block 9 is removed, and then the vertical rod 8 is held and pulled upward, so as to pull out the filter screen 7 through the vertical rod 8. At this time, the new filter screen 7 is inserted into the valve body 1, and the sealing block 9 is covered, and the first bolt 10 is re-screwed to complete the replacement of the filter screen 7.
