[0002] As an efficient and multifunctional valve, the core of the ball valve is a sphere with a circular channel as an opening and closing element. The sphere rotates along an axis perpendicular to the fluid channel to open and close the channel. The traditional ball valve design usually includes a sphere with a through hole, which is carefully placed on the valve seat. Through a simple rotation action, the flow of the fluid can be easily controlled; ball valves have the advantages of low fluid resistance, simple structure, tight and reliable, easy operation, fast opening and closing, and a wide range of applications.

Since the ball valve lacks a filtering structure, when a medium containing impurities enters the ball valve, the impurities will aggravate the wear of the valve core and the valve seat, affecting the service life of the ball valve. Moreover, when replacing the valve core and the valve seat, it is necessary to first turn the locking nut to remove it, and then remove the joint, the sealing ring and the valve bonnet in turn, and then release the connection between the valve stem and the valve core, and finally take the valve seat and the valve core out of the valve body in turn. The replacement and maintenance process of the valve seat and the valve core is complicated, and due to the limited field of view, it is not conducive to the maintenance and replacement of the valve seat and the valve core, and the operation is difficult.

[0025] The left valve body 1 and the right valve body 2 are detachably connected. Specifically, the left valve body 1 is provided with a plurality of mounting holes 15, and the right valve body 2 is provided with a plurality of mounting holes 16 corresponding to the mounting holes 15. A fixing bolt 17 is passed through the mounting hole 15, and the fixing bolt 17 is threadedly connected with the mounting hole 16. The fixing bolt 17 cooperates with the mounting hole 15 and the mounting hole 16 to achieve the connection between the left valve body 1 and the right valve body 2. The connection is stable and reliable. When disassembling, it is only necessary to rotate the fixing bolt 17 to release the threaded connection between the fixing bolt 17 and the mounting hole 16. After the fixing bolt 17 is removed, the left valve body 1 can be separated from the right valve body 2. The disassembly is convenient and quick.

[0026] Furthermore, a positioning protrusion 13 is provided on the left valve body 1. Preferably, there are several positioning protrusions 13 and they are integrally arranged with the left valve body 1. A positioning groove 14 is provided on the right valve body 2. Preferably, there are several positioning grooves 14 and they correspond one to one with the several positioning protrusions 13. The positioning protrusion 13 can be inserted into the positioning groove 14. During installation, the positioning protrusion 13 is inserted into the positioning groove 14 to ensure the relative stability of the left valve body 1 and the right valve body 2 during installation, so that the mounting hole 15 is aligned with the mounting hole 2 16, which can effectively improve the efficiency during installation and reduce the difficulty during installation.

[0027] The valve core 3 is rotatably arranged in the right valve body 2, one end of the valve stem 6 is connected to the valve core 3, and the other end of the valve stem 6 extends out of the right valve body 2 and is connected to the handle 7. After rotating the handle 7, the valve core 3 can be driven to rotate through the valve stem 6. It should be noted that, in the present embodiment, a limiting block 18 is arranged on the valve stem 6, and a mounting seat 19 is installed on the right valve body 2. The right valve body 2 and the mounting seat 19 are connected by two limiting bolts 20. The handle 7 can drive the limiting block 18 to rotate so that the side walls of the limiting block 18 are respectively abutted against the side walls of the two limiting bolts 20. The circumferential limit of the limiting block 18 is achieved by the two limiting bolts 20, thereby trying to limit the rotation angle of the valve stem 6 and the valve core 3.

[0028] The limit block 18 is provided with a linkage hole 21 , and the handle 7 is provided with a linkage protrusion 22 , which is inserted into the linkage hole 21 , that is, when the handle 7 rotates, the limit block 18 can be driven to rotate through the linkage protrusion 22 cooperating with the linkage hole 21 .

[0029] The left valve body 1 cooperates with the valve core 3 to press the valve seat 1 4, and the right valve body 2 cooperates with the valve core 3 to press the valve seat 2 5, so as to ensure the stability of the valve seat 1 4, valve seat 2 5 and the valve core 3, and because the valve seat 1 4 is pressed by the left valve body 1 and the valve core 3, and the valve seat 2 5 is pressed by the right valve body 2 and the valve core 3, after the left valve body 1 is separated from the right valve body 2, the valve seat 1 4 and the valve body 2 can be directly removed, which is simple to operate and convenient for later maintenance. It should be noted that since the left valve body 1 is separated from the right valve body 2, the user's field of view during operation is expanded, which is more conducive to the maintenance and replacement of the valve core 3, and reduces the difficulty of operation.

[0030] The left valve body 1 is provided with a water inlet 8 , the right valve body 2 is provided with a water outlet 9 , and the valve core 3 is provided with a water through hole 10 , which can connect the water inlet 8 with the water outlet 9 .

[0031] A sealing gasket 26 is provided between the left valve body 1 and the right valve body 2. The sealing gasket 26 is annular and is used to seal the left valve body 1 and the right valve body 2 to ensure the sealing performance therebetween.

[0032] A positioning groove 11 is provided in the left valve body 1, and a filter screen 12 is detachably provided in the positioning groove 11. The left valve body 1 cooperates with the valve seat 1 4 to press the filter screen 12 into the positioning groove 11, so as to ensure the stability of the filter screen 12. The impurities in the fluid are filtered through the filter screen 12 to prevent the impurities from aggravating the wear of the valve core 3, the valve seat 1 4 and the valve seat 2 5, thereby affecting the service life.

[0033] The left valve body 1 is provided with a sewage channel 23 connected to the outside. The sewage channel 23 is inclined, and a plug 24 is detachably connected to the outlet of the sewage channel 23. The plug 24 is threadedly connected to the outlet of the sewage channel 23. A guide slope 25 is provided in the left valve body 1. The guide slope 25 extends from top to bottom to the entrance of the sewage channel 23, and the higher end of the guide slope 25 is close to the filter 12. Impurities in the medium are blocked by the filter 12. In order to avoid the accumulation of impurities in the left valve body 1, the impurities are guided by the guide slope 25, so that the impurities enter the sewage channel 23. After the user removes the plug 24, the impurities in the sewage channel 23 can be discharged.

[0034] The specific embodiments described in this article are merely examples of the spirit of the utility model; technicians in the technical field to which the utility model belongs can make various modifications or additions to the described specific embodiments or replace them in a similar manner, but will not deviate from the spirit of the utility model or exceed the scope defined by the attached claims.
