[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0025] Refer to Figures 1-5 , an embodiment provided by the present utility model: a jacketed thermal insulation ball valve, including a valve body 1, a fixed frame 2 is fixedly connected to the left side of the top of the valve body 1, a mounting plate 6 is arranged on the inner wall of the fixed frame 2, a filter screen 7 is fixedly connected to the inner wall of the mounting plate 6, a connecting pipe 9 is fixedly connected to the top of the valve body 1, a groove 10 is opened at the top of the connecting pipe 9, and a mounting ring 15 is arranged on the inner wall of the groove 10. The left side of the inner wall of the protective cover 4 is fixedly connected with a spring 5, a limit groove 8 is opened on the inner wall of the mounting plate 6, the outer wall of the clamping rod 3 is arranged on the inner wall of the limit groove 8, the shape of the inner wall of the limit groove 8 fits the clamping rod 3, and the right end of the spring 5 is fixedly connected to the left end of the fixed frame 2.

[0026] Specifically, when the valve body 1 is in use, the liquid flows from left to right, and the solid particles or impurities in the liquid are filtered by the filter screen 7, which can prevent solid particles or impurities from entering the pipeline system and related equipment, thereby prolonging the service life of the equipment and reducing the maintenance cost. When the filter screen 7 needs to be replaced or cleaned, first pull the clamping rod 3 to the left, take out the clamping rod 3 from the limit groove 8, release the limit on the mounting plate 6, and then the mounting plate 6 can be taken out upward, so as to facilitate the replacement or cleaning of the filter screen 7, improve work efficiency, and at the same time, the protective cover 4 can prevent dust from affecting the service life of the spring 5.

[0027] One end of each button 12 facing inwards is fixedly connected to a bidirectional telescopic rod 13. Opposite ends of the bidirectional telescopic rods 13 are fixedly connected to clamping blocks 14. A plurality of clamping grooves 16 are formed in the outer wall of the mounting ring 15. The middle part of the outer wall of the bidirectional telescopic rod 13 is fixedly connected to the inner wall of the fixed ring 11. The outer walls of the clamping blocks 14 are arranged on the inner walls of the clamping grooves 16. The shape of the clamping block 14 fits the clamping groove 16. The inner wall of the fixed ring 11 is fixedly connected to the outer wall of the connecting pipe 9. The shape of the mounting ring 15 fits the groove 10.

[0028] Specifically, when it is necessary to repair the valve body 1, only need to press the button 12 inward on one side. The button 12 drives one side of the bidirectional telescopic rod 13 to expand and contract, and at the same time the other side expands and contracts simultaneously, driving the clamping block 14 to move, taking the clamping block 14 out of the clamping groove 16, and then the mounting ring 15 can be taken out upwards, and the mounting ring 15 and the operating handle can be quickly disassembled from the connecting pipe 9, thus facilitating the workers to repair the inside of the valve body 1.

[0029] Working principle: When the valve body 1 is in use, the liquid flows from left to right. The filter screen 7 filters the solid particles or impurities in the liquid, which can prevent the solid particles or impurities from entering the pipeline system and related equipment, thereby prolonging the service life of the equipment and reducing the maintenance cost. At the same time, when it is necessary to replace and clean the filter screen 7, first pull the clamping rod 3 to the left, take the clamping rod 3 out of the limiting groove 8, release the limit on the mounting plate 6, and then the mounting plate 6 can be taken out upwards, thus facilitating the replacement or cleaning of the filter screen 7 and improving the work efficiency. During installation, insert the mounting plate 6 into the fixed frame 2, pull the clamping rod 3, align the clamping rod 3 with the limiting groove 8, and then release the clamping rod 3. Through the spring 5, drive the protective cover 4 and the clamping rod 3 to move to the right, and snap the clamping rod 3 into the limiting groove 8 to limit the mounting plate 6, and the installation can be completed. At the same time, when it is necessary to repair the valve body 1, only need to press the button 12 inward on one side. The button 12 drives one side of the bidirectional telescopic rod 13 to expand and contract, and at the same time the other side of the bidirectional telescopic rod 13 expands and contracts simultaneously, driving the clamping block 14 to move, taking the clamping block 14 out of the clamping groove 16, and then the mounting ring 15 can be taken out upwards, and the mounting ring 15 and the operating handle can be quickly disassembled from the connecting pipe 9, thus facilitating the workers to repair the inside of the valve body 1. During installation, first snap the mounting ring 15 into the groove 10, align the clamping groove 16 with the clamping block 14, and then press the button 12 to snap the clamping block 14 into the clamping groove 16 to limit the mounting ring 15, and the installation can be completed. The operation is simple.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
