Description

Technical Field

[0001] The invention relates to the technical field of stop valves, and in particular to a stop valve with a cleaning function. Background Art

[0002] The stop valve, also known as the gate valve, is a forced sealing valve. When the valve is closed, pressure must be applied to the valve disc to force the sealing surface to prevent leakage. When the medium enters the valve from under the valve disc, the resistance that the operating force needs to overcome is the friction between the valve stem and the packing and the thrust generated by the pressure of the medium. The force to close the valve is greater than the force to open the valve, so the diameter of the valve stem must be large, otherwise the valve stem will bend.

[0003] After searching, the existing patent (publication number: CN208221614U) discloses a stop valve, including a valve seat, a spherical cavity is welded at the bottom of the valve seat, and row pipes are welded on the left and right sides of the spherical cavity, and disks are welded on the left and right sides of the row pipes, and a filter seat is clamped on the inner side of the disk, and a flow cavity is opened in the middle of the filter seat, and the inner cavity of the filter seat is symmetrically opened with notches, and a semicircular filter disc is arranged in the notch, and the filter disc is opened with filter holes, and a connecting block is welded on one side of the filter disc, and a bearing is installed on the side of the connecting block away from the filter disc. The stop valve can filter impurities in sewage before the sewage enters the stop valve by setting a filtering mechanism, so that the water flowing into the stop valve is clean and free of impurities, thereby preventing the stop valve from being blocked. At the same time, the stop valve can also remove impurities such as dust in the air to prevent dust from entering the inside of the stop valve.

[0004] However, in the implementation of the relevant technology, it was found that the above-mentioned problem exists: when the above-mentioned stop valve filters impurities in the water through the overlap of two semicircular filter discs, the filtered impurities will adhere to the surface of one side of the filter disc. After long-term use, the impurities will accumulate on the surface of the filter disc, which may further cause the filter disc and the stop valve itself to be blocked, and it is difficult to clean the impurities on the surface of the filter disc.

[0021] A plurality of through holes 9 are formed through the side wall of the swivel 5, and the plurality of through holes 9 are distributed in a circular shape at equal intervals on the side wall of the swivel 5. By setting the plurality of through holes 9, the impurities cleaned from the filter 4 can more fully pass through the through holes 9 and fall directly into the sewage outlet 10, and the impurities are prevented from falling on the inner wall of the swivel 5 and accumulating.

[0022] During use, when it is necessary to clean the impurities on the surface of one side of the filter 4, the driving mechanism 8 drives the swivel 5 to rotate, and the swivel 5 will drive the several cleaning components 6 to rotate, so that the several cleaning components 6 rotate along the surface of one side of the filter 4, and the several cleaning components 6 can clean the impurities on the surface of one side of the filter 4. These cleaned impurities will directly fall into the drain outlet 10 at the bottom of the inner wall of the water inlet head 2. The driving mechanism 8 will also drive the drain mechanism 7 to discharge the impurities that fall into the drain outlet 10, so that the impurities cleaned from the filter 4 can be discharged to the outside of the valve body 1, and the cleaning process of the filter 4 can be completed.

[0031] See also Figure 4 , Figure 5 and Figure 6 The driving mechanism 8 includes a motor 81, a first transmission member and a second transmission member. The motor 81 is fixedly connected to the lower end of the connecting tube 71.

The second transmission member is arranged between the opposite ends of the two extrusion screws 78, and the output end of the motor 81 is connected to the second transmission member through a rotating shaft.

[0035] The working principle and use process of the present invention are as follows: during use, when it is necessary to clean the impurities on the surface of one side of the filter disc 4, first, by respectively regulating the two second electric cylinders 73, the output ends of the two second electric cylinders 73 will respectively pull the two baffles 74 to open outward, so that the connecting pipe 71 can be opened, and then, by starting the motor 81, the output end of the motor 81 will drive the rotating shaft to rotate, and the rotating shaft will drive the gear 83 to rotate, and the gear 83 will drive the annular surface gear 82 to rotate, and the annular surface gear 82 will drive the rotating ring 5 to rotate, and the rotating ring 5 will drive a plurality of cleaning soft brushes 62 to rotate, so that the plurality of cleaning soft brushes 62 rotate along the surface of one side of the filter disc 4, and the plurality of cleaning soft brushes 62 can clean the impurities on the surface of one side of the filter disc 4, and these cleaned impurities will directly fall into the sewage outlet 10 at the bottom of the inner wall of the water inlet head 2, and the impurities will directly fall into the sewage outlet 10 after falling into the sewage outlet 10. When the filter 4 is cleaned, the motor 81 drives the first bevel gear 84 to rotate through the rotating shaft. The first bevel gear 84 drives the two second bevel gears 85 to rotate at the same time. The two second bevel gears 85 drive the two extrusion screws 78 to rotate at the same time. The impurities falling into the connecting pipe 71 are respectively extruded into the two extrusion pipes 76 through the two rotating extrusion screws 78. Finally, these impurities are discharged through the two drain pipes 77 respectively, so that the impurities cleaned from the filter 4 can be discharged to the outside of the valve body 1, and the cleaning process of the filter 4 can be completed. After cleaning, the two second electric cylinders 73 are respectively regulated, and the output ends of the two second electric cylinders 73 respectively push the two baffles 74 to merge together, so that the connecting pipe 71 can be sealed and blocked to prevent water from entering the connecting pipe 71.
