Description

Technical Field

[0001] The utility model relates to the technical field of rotary ball valves, in particular to a novel rotary ball valve. Background Art

[0002] The rotary ball valve is a type of valve that combines the characteristics of a ball valve and a butterfly valve, and controls the flow of fluid by rotating the ball. The rotary ball valve has the advantages of large flow, small opening and closing force, and good sealing, and is suitable for control and regulation on pipelines. It is usually used in occasions where frequent adjustment or closing of fluids is required, and is one of the commonly used valve types.

[0003] However, the existing rotary ball valve is not provided with a filtering structure. Since there are impurities in the fluid, there are impurities in the valve body of the rotary ball valve, which will subsequently affect the normal use of the valve disc and shorten the service life of the rotary ball valve. Utility Model Content

[0004] The main purpose of the utility model is to provide a new type of rotary ball valve, which has solved the above-mentioned problems.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a novel rotary ball valve, including a rotary ball valve body and a filtering structure;

The filter screen is arranged in the cylinder, an opening is arranged at the lower end of the cylinder, the collecting frame is arranged at the lower end of the opening, and an openable closing plate is arranged at the lower end of the collecting frame.

[0007] The beneficial effect is that the fluid first passes through the filter screen in the cylinder and then enters the valve body of the rotary ball valve. When the fluid passes through the filter screen, the filter screen filters the impurities in the fluid, and the impurities after long-term filtration enter the collection frame through the opening for unified collection. After a period of time, the closing plate is opened, and the personnel can clean out the impurities in the collection frame, and then the closing plate can be used again to close the lower end of the collection frame, and then the impurities in the collection frame are cleaned uniformly regularly to avoid residual impurities in the cylinder and affect the filtering effect of the filter screen, and the filtering structure can also be removed from the rotary ball valve for overall cleaning, so that there will be no impurities in the valve body of the rotary ball valve, the valve disc will not be affected in subsequent use, and the service life of the rotary ball valve can be extended.

[0008] The cylinder is detachably connected to the rotary ball valve body through a flange.

[0009] Ear plates are respectively arranged on both sides of the lower end of the collecting frame, and insertion holes are arranged on the ear plates on both sides. Connecting holes are respectively arranged on both sides of the closing plate, and the insertion holes and the connecting holes are used for inserting bolts.

[0010] A rotating rod is arranged at the front side of the filter screen, one end of the rotating rod is rotatably connected to the inner wall of the cylinder, the other end of the rotating rod is arranged to pass through one side of the cylinder, and a plurality of cams are arranged in the radial direction on the rotating rod.

[0016] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0017] like Figures 1 to 4 As shown, the utility model provides a novel rotary ball valve, comprising a rotary ball valve body 10 and a filter structure 20;

[0018] The filter structure 20 is detachably connected to one side of the rotary ball valve body 10, and includes a cylinder 21, a filter screen 22 and a collection frame 23. The filter screen 22 is arranged in the cylinder 21, and an opening 24 is arranged at the lower end of the cylinder 21. The collection frame 23 is arranged at the lower end of the opening 24, and an openable closing plate 25 is arranged at the lower end of the collection frame 23.

[0019] During the working process, the fluid first passes through the filter screen 22 in the cylinder 21 and then enters the valve body 11 of the rotary ball valve 10. When the fluid passes through the filter screen 22, the filter screen 22 filters the impurities in the fluid. The impurities filtered for a long time enter the collection frame 23 through the opening 24 for unified collection. After a period of time, the closing plate 25 is opened, and the personnel can clean up the impurities in the collection frame 23. Then, the closing plate 25 can be used again to close the lower end of the collection frame 23. Through the function of the filter screen 22, the impurities in the fluid are first filtered, and then the impurities in the collection frame 23 are uniformly cleaned regularly to avoid residual impurities in the cylinder 21 and affect the filtering effect of the filter screen 22. In addition, the filter structure 20 can also be disassembled from the rotary ball valve 10 for overall cleaning, so that there will be no impurities in the valve body 11 of the rotary ball valve 10, and the valve disc 8 will not be affected in subsequent use, which can extend the service life of the rotary ball valve 10.

[0020] The cylinder 21 is detachably connected to the ball valve body 10 via the flange 5 .

[0021] Ear plates 31 are respectively provided on both sides of the lower end of the collecting frame 23, and insertion holes (not shown in the drawings) are provided on the ear plates 31 on both sides. Connecting holes (not shown in the drawings) are respectively provided on both sides of the closing plate 25, and the insertion holes and the connecting holes are used for inserting bolts 32.

[0022] The personnel unscrew the nut 33 on the bolt 32, and then the bolt 32 is removed from the connecting hole and the insertion hole, so that the closing plate 25 is separated from the collecting frame 23, and the impurities collected in the collecting frame 23 can be cleaned. Then, the closing plate 25 is closed at the lower end of the collecting frame 23 by the action of the bolt 32 and the nut 33.

[0023] A rotating rod 41 is arranged at the front side of the filter screen 22 , one end of the rotating rod 41 is rotatably connected to the inner wall of the cylinder 21 , and the other end of the rotating rod 41 is arranged to pass through one side of the cylinder 21 . A plurality of cams 42 are arranged in the radial direction on the rotating rod 41 .

[0024] By manually rotating the rotating rod 41, the cam 42 on the rotating rod 41 contacts the filter 22, knocking the filter 22 to knock off the impurities on the filter 22, thereby preventing the impurities on the filter 22 from affecting the filtering effect of the filter 22.

[0025] In addition, the ball valve body 10 is a prior art, and will not be described in detail here.

[0026] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
