Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of valves, in particular to a filtering ball valve. Background Art
[0002] Valves are control components in fluid delivery systems and have functions such as shutoff, regulation, flow diversion, backflow prevention, pressure stabilization, flow diversion or overflow pressure relief. Ball valves, as a type of valve, are mainly used in pipelines to cut off, distribute and change the flow direction of the medium. They can be closed tightly by simply rotating 90 degrees and using a very small torque.
[0003] Filter ball valves are widely used. The working principle of the filter ball valve is: a filter screen is arranged inside the ball valve. When the fluid medium passes through the ball valve, the filter screen can filter it to remove impurities and dirt. Since sewage often carries obstacles that can easily block the filter screen, when the filter screen is saturated, it will cause the water flow in the flow channel to be blocked. In summary, a filter ball valve is proposed to solve the above problems. Utility Model Content

[0006] By adopting the above technical solution, the turntable is sent into the flow by the sliding rod, and the control component can control a number of scraping hooks to move toward the filter to scrape the obstructions on the filter, disrupting the saturated state of the filter and effectively clearing the filter.
[0007] It is further configured that: the outer scraping contour surface formed by the rotation of the scraping hook is in contact with a side of the filter screen facing the scraping hook.
[0008] By adopting the above technical solution, the obstacles can be scraped off the filter screen more effectively by arranging the outer scraping contour surface to fit the side of the filter screen facing the scraping hook.
[0009] It is further configured as follows: the control component includes a driving rope connected to the driving part, which is arranged on the sliding rod and has a connecting channel extending to the outside world along the length direction of the sliding rod. The free end of the driving rope passes through the connecting channel and extends to the outside world to form a control end. The reset part is provided with a reset spring that resets the turntable to a state perpendicular to the sliding rod.
[0010] By adopting the above technical solution, through the setting of the control end, the control end can be pulled from the outside to control the driving rope, and the operation is simple; the reset spring can cooperate with the driving rope to realize a plurality of reciprocating movements of the scraping hooks, and when the reset spring resets the turntable to a vertical state with the sliding rod, the obstacle located on the lower side of the turntable is brought into the collecting bottle by the turntable during the movement of the sliding rod to the side of the collecting bottle, so that the filter is not easy to be saturated.
[0011] It is further configured as follows: a limiting ring is installed at the entrance of the flow channel, a pipe sleeve is provided between the limiting ring and the seal and is attached to the inner wall of the flow channel, the filter screen is installed in the pipe sleeve, and a receiving ring is provided in the pipe sleeve at a position between the flow channel opening and the turntable, the receiving ring is used for fluid to pass through, and when the fluid impacts the receiving ring, the receiving ring drives the seal to move toward the side of the sphere through the sleeve.
[0012] By adopting the above technical solution, when the fluid impacts the receiving ring, the sleeve gives the seal a pressing force toward the ball, which can effectively prevent leakage between the dynamic seal and the valve body.
[0013] It is further configured as follows: the limiting sleeve is threadedly connected to the flow channel, and the receiving ring and the filter screen are both threadedly connected to the pipe sleeve.
[0014] By adopting the above technical solution, the limiting sleeve is threadedly connected to the flow channel, so that the pipe sleeve can be easily taken out of the flow channel, so that the filter screen and the receiving ring can be replaced.
[0015] It is further configured that: a sealing ring is provided between the collecting bottle and the sliding rod, and between the sliding rod and the driving rope.
[0016] By adopting the above technical solution and setting the sealing ring, leakage of the fluid can be effectively prevented. BRIEF DESCRIPTION OF THE DRAWINGS
