[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Example: Figure 1-6 As shown, the utility model provides a forged steel stop valve with a filtering function, including a valve body 1 and a valve cover 11. The valve cover 11 is arranged on the top of the valve body 1 and a valve cavity is formed between the two. A valve core 13 is provided in the valve body 1. A valve stem 12 is passed through the center of the valve body 1 and the valve cover 11. The bottom end of the valve stem 12 is fixedly connected to the valve core 13 and the valve stem 12 can drive the valve core 13 to realize reciprocating motion along the axial direction of the valve stem 12. A water outlet 14 and a water inlet 15 connected or blocked by the valve core 13 are provided in the valve body 1. A valve handle 16 is fixedly connected to the top of the valve stem 12. A first slot 5 is opened in the valve body 1 on the side of the water inlet 15. The first slot 5 is provided with an insert plate 2, and a circular groove 23 is provided in the insert plate 2 to match the filter plate 4. The valve body 1 is provided with a second slot 52 below the first slot 5, and the bottom of the insert plate 2 can be inserted into the second slot 52. The same third slot 6 is provided on both sides of the second slot 52, and a card block 61 is slidably provided in the third slot 6. A telescopic rod 62 is fixedly connected to the third slot 6, and the other end of the telescopic rod 62 is fixedly connected to the card block 61. The card block 61 and the third slot 6 are also connected by a spring 63 sleeved on the telescopic rod 62. Fourth slots 611 that match the card block 61 are also provided on both sides of the bottom end of the insert plate 2.

[0020] The four corners of the circular groove 23 are each provided with a first slide groove 24, and the filter plate 4 can slide in the circular groove 23 through the first slide groove 24; a latch 3 is inserted through the center of the top of the plug plate 2 and the filter plate 4; when installing or replacing the filter plate 4, it can be installed or removed at will through the first slide groove 24, and the filter plate 4 is fixed and limited by the latch 3.

[0021] Two symmetrically distributed first sliders 22 are fixedly connected to one side of the plugboard 2, and a second slide groove 51 that fits with the first slider 22 is opened on the inner side of the first slot 5. The plugboard 2 can slide in the second slide groove 51 through the first slider 22; a handle 21 is fixedly connected to the top of the plugboard 2; when the plugboard 2 needs to be inserted or pulled out, the handle 21 can be used to cooperate with the first slider 22 and the second slide groove 51 to better operate and limit the plugboard 2 at the same time.

[0022] The clamping block 61 is located below one side of the spring 63 and is fixedly connected to an insertion rod 64 that passes through the valve body 1; the insertion rod 64 is rotatably connected to a rotating rod 65 at one end away from the clamping block 61, and a clamping groove 651 that fits with the rotating rod 65 is provided on the valve body 1; when it is necessary to plug or unplug the plug plate 2, it is only necessary to pull the insertion rod 64 and then rotate the rotating rod 65 so that the rotating rod 65 is clamped into the clamping groove 651 for fixed limit.

[0023] The bottom of the plug plate 2 and the second slot 52 are narrower than the top of the plug plate 2, so that the top of the plug plate 2 can fit the valve body 1, and at the same time, the plug plate 2 can be better inserted into the second slot 52, which facilitates the limiting operation of the plug plate 2.

[0024] Working principle: When the staff needs to install or replace the filter plate 4, they only need to pull the insertion rod 64 and then rotate the rotating rod 65 so that the rotating rod 65 can be locked in the locking groove 651 for fixed limit, and then pull out the plug plate 2 through the handle 21, and then pull out the latch 3, and then cooperate with the first slide groove 24 to install or replace the filter plate 4. After the replacement or installation is completed, insert the latch 3, and then align the first slider 22 fixedly connected on the plug plate 2 with the second slide groove 51 and insert it. After the insertion is completed, pull and rotate the rotating rod 65 to make the rotating rod 65 disengage from the locking groove 651, and then under the action of the spring 63 and the telescopic rod 62, the card block 61 is locked into the fourth slot 611, thereby fixing the plug plate 2 and completing the operation of installing or replacing the filter plate 4. This operation is more convenient, saves the workload of the staff, and at the same time achieves the purpose of filtering through the filter plate 4.
