[0023] Reference Figures 1 to 5 As shown, to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a ball valve ball, comprising a ball body 1, a through hole 2 for medium to pass through is opened in the middle of the ball body 1, a mounting ring 3 is provided in the through hole 2, a filter assembly 4 is detachably mounted on the mounting ring 3, and the filter assembly 4 includes a fixing ring 41 and a filter screen 42, the fixing ring 41 is detachably mounted on the mounting ring 3, and together with the mounting ring 3, forms an installation space for installing the filter screen 42;

[0024] A guide arc surface 31 is provided on the opposite side of the fixing ring 41 and the mounting ring 3 , and a rubber ring 32 is provided on the opposite side of the fixing ring 41 and the mounting ring 3 .

[0025] By installing the filter assembly 4 in the spherical body 1, the fluid medium can be filtered through the filter assembly 4 when the medium is flowing, thereby reducing impurities in the fluid medium. When the spherical body 1 is closed, the filter assembly 4 can be separated from the liquid, thereby avoiding the filter assembly 4 being immersed in the liquid for a long time.

[0026] Furthermore, the design of the rubber ring 32 and the guide arc surface 31 can serve as a protective device during the liquid impact process, thereby increasing the service life of the equipment.

[0027] And because the fixing ring 41 and the mounting ring 3 are both provided with the guide arc surface 31 and the rubber ring 32, the ball valve can be used in both directions. Figure 1 For example, the liquid medium can flow from left to right and from right to left.

[0028] The utility model is further configured as follows: the filter screen 42 includes a connecting portion 43 and a mesh portion 44 , the connecting portion 43 is configured in an I-shaped structure, and the middle portions of both sides of the connecting portion 43 are provided with assembly grooves 431 that cooperate with the rubber ring 32 .

[0029] like Figure 2 As shown, the rubber ring 32 can be embedded between the fixing ring 41 and the filter screen 42 respectively, thereby fixing the rubber ring 32 .

[0030] The present invention is further configured as follows: a rubber groove 33 is provided on both the mounting ring 3 and the fixing ring 41 , the rubber ring 32 is detachably mounted in the rubber groove 33 , and the rubber groove 33 is configured to be a “convex” structure.

[0031] As Figure 2 shown, the cross-sections of the rubber groove 33 and the rubber ring 32 are both convex structures, which can facilitate the installation of the rubber groove 33, thereby improving the installation strength of the rubber ring 32.

[0032] The present utility model is further configured as: a first fixing groove 34 is provided inside the rubber groove 33, and a second fixing groove 35 is provided outside the rubber groove 33;

[0033] The connecting portion 43 includes a first fixing edge 432 located inside and a second fixing edge 433 located outside;

[0034] When the rubber ring 32 is snapped into the assembly groove 431, the first fixing edge 432 and the second fixing edge 433 are respectively inserted into the first fixing groove 34 and the second fixing groove 35.

[0035] The design of this structure has the following installation process: 1. Install the two rubber rings 32 into the rubber grooves 33 of the fixed ring 41 and the mounting ring 3 respectively;

[0036] 2. Insert the first fixing edge 432 and the second fixing edge 433 on both sides of the filter net 42 into the first fixing groove 34 and the second fixing groove 35 of the fixed ring 41 and the mounting ring 3 respectively to form the fixation of the filter net 42;

[0037] 3. Snap the mounting ring 3 and the fixed ring 41 together and then fix them with bolts. (As Figure 2 , Figure 4 , Figure 5 shown, a connection hole is penetrated through the fixed ring 41, and a fixing block is provided on the mounting ring 3. Through the cooperation of the fixing block and the connection hole, and then a bolt is screwed on the fixing block, the fixation of the mounting ring 3 and the fixed ring 41 can be formed, and at the same time, the filter net 42 is fixed)

[0038] The present utility model is further configured as: both the filter assembly 4 and the mounting ring 3 are installed in the middle of the through hole 2.

[0039] The present utility model is further configured as: a valve rod 11 is connected to the upper end of the middle part of the sphere body 1, a limiting rod 12 is rotatably connected inside the valve rod 11, a limiting hole 411 is provided at the upper end of the fixed ring 41, a linkage groove communicating with the through hole 2 is provided on the sphere body 1, a linkage rod 13 is slidably connected in the linkage groove, the upper end of the linkage rod 13 is in linkage cooperation with the limiting rod 12, and the lower end is used for inserting into the limiting hole 411.

[0040] The design of this structure, as Figure 1 and Figure 5As shown in the figure, the connection methods of the limit rod 12 include the following two types: 1. The limit rod 12 is screwed into the valve rod 11 and can move up and down along the valve rod 11 when the limit rod 12 rotates; 2. The limit rod 12 rotates idly in the valve rod 11. The lower end of the limit rod 12 is provided with a high surface and a low surface. When the high surface abuts against the linkage rod 13, the linkage rod 13 can move downward until it is inserted into the limit hole 411. When it rotates until the low surface faces the linkage rod 13, the linkage rod 13 separates from the limit hole 411 under the action of the return spring.

[0041] As Figure 5 shown in the figure, a return spring is arranged on the outer side of the linkage rod 13, and the linkage rod 13 can realize the reset operation of moving up and down through the return spring.
