Description

Technical Field

[0001] The invention relates to the technical field of kettle bottom ball valves, and in particular to a kettle bottom ball valve with an anti-leakage structure. Background Art

[0002] The kettle bottom ball valve is a valve installed at the bottom of the pressure vessel. It is mainly used to control and regulate the flow of the medium in the container. It has the characteristics of rapid switching, good sealing performance, simple structure and easy maintenance. It is widely used in chemical, petroleum, pharmaceutical and other industries to cut off or connect the fluid in the pipeline.

[0003] When the kettle bottom ball valve is in use, the medium is cut off by the rotation of the ball valve, but a part of the medium is likely to remain in the internal channel of the ball valve, and the remaining medium will be washed away after the next opening. If the flowing medium cannot be retained for a long time, part of the medium inside the ball valve is likely to change in quality after the medium is cut off. After the next opening, it will be mixed with the new medium, which will easily affect the quality of the new medium and make it inconvenient to use. Based on these problems, Chinese patent CN115654169A discloses a kettle bottom ball valve sealing assembly. After the ball valve body cuts off the medium, the fixing bolt is rotated to unlock the sliding rod, and the sliding rod is pushed upward to drive the pulling rod to move upward, so that the blocking plug moves upward and the discharge hole is opened. Then the auxiliary ring is rotated to lock the sliding rod with the cooperation of the mounting block, and the remaining medium in the ball valve body flows out along the discharge hole and the sliding groove, thereby achieving the purpose of conveniently discharging the remaining medium in the ball valve body. It is simpler, more convenient and more practical to use.

[0004] If there are particles in the medium cut off by the ball valve body, some of the medium will adhere to the inner wall of the discharge hole when the medium is discharged from the discharge hole. If the particle medium accumulates under the plugging plug, it is easy to cause the bottom surface of the plugging plug to fail to fit tightly with the top surface of the discharge hole, thereby causing medium leakage.

[0009] As a further description of the above technical solution: One end of the outer wall of the bottom valve shell and the top valve shell is fixedly connected with a first arc ring, and the other end of the outer wall of the bottom valve shell and the top valve shell is fixedly connected with a second arc ring. The first arc ring and the second arc ring are each provided with two groups, and the first arc ring and the second arc ring are of the same size.

[0010] As a further description of the above technical solution: One end of the inner wall of the bottom valve shell and the top valve shell is sleeved with an insert ring, one end face of the insert ring is fixedly connected to an outer tube, one end of the outer wall of the outer tube is fixedly connected to a first flange, the first flange and the second arc-shaped ring inner wall are both inserted with a second threaded rod, and one end of the outer wall of the second threaded rod is threadedly connected with a second nut.

[0011] As a further description of the above technical solution: A second flange is fixedly connected to the outer edge of one end face of the outer tube, a collar is sleeved on the inner wall of the second flange, an inner tube is fixedly connected to the bottom end of the collar, a first screen is fixedly connected to the bottom end of the inner wall of the collar, and a second screen is fixedly connected to the bottom end of the inner wall of the inner tube.

[0012] As a further description of the above technical solution: A hollow tube is fixedly connected to the bottom of the discharge tube, a second shaft ring is fixedly connected to the bottom of the hollow tube, an inner wall of the second shaft ring is rotatably connected to an axis core, and a turntable is fixedly connected to the bottom of the axis core.

[0013] As a further description of the above technical solution: A baffle is fixedly connected to the top of the shaft core, a scraper is fixedly connected to one end of the top of the baffle, a discharge pipe runs through the bottom end of the inner wall of the hollow tube, and a sealing cap is threadedly connected to one end of the outer wall of the discharge pipe.

[0014] As a further description of the above technical solution: A side block is fixedly connected to the bottom end of one side of the inner wall of the U-shaped frame, a return spring column is installed in the side block, and an insert block is fixedly connected to the bottom end of the return spring column.

[0015] As a further description of the above technical solution: The outer wall of the second shaft ring is fixedly connected with a fan-shaped plate, and both ends of the fan-shaped plate are provided with plug holes penetrating up and down, and the outer wall of the plug block can be plugged with the inner walls of the plug holes at both ends of the fan-shaped plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The opposite surfaces of the first rubber strip and the second rubber strip are tightly attached to each other, which can improve the sealing performance of the connection between the bottom valve shell and the top valve shell, thereby achieving a leakage prevention effect. The convex arc surface of the arc-shaped slide plate is tightly attached to the arc-shaped concave surface of the arc-shaped hollow plate, which has a blocking effect on the discharge hole. The outer wall of the arc-shaped scraper rod can rotate along the inner wall of the ball valve body to remove the particles attached to the inner wall of the ball valve body. When the turntable is rotated, the arc-shaped slide plate and the arc-shaped scraper rod at the top of the vertical rod will rotate together. At this time, the arc-shaped slide plate will remove the particles accumulated at the discharge hole. At the same time, the residual medium in the ball valve body will flow out normally from the discharge hole. After the residual medium is discharged, the convex arc surface of the arc-shaped slide plate is re-attached to the arc-shaped concave surface of the arc-shaped hollow plate, thereby avoiding medium leakage.

[0017] By setting a connecting structure between the second mounting plate, the first threaded rod and the first nut, the bottom valve shell and the top valve shell can be fixed together. By setting a simple connecting method between the first nut and the first threaded rod, the disassembly and assembly steps between the bottom valve shell and the top valve shell are made more convenient and quick.

[0018] By setting the second flange, the kettle bottom ball valve can be fixed under the reactor, and the outer wall of the collar is in close contact with the inner wall of the second flange. When the medium flows into the collar, the medium will not flow into the gap between the outer wall of the collar and the inner wall of the second flange, which is beneficial to improve the comprehensiveness of the first screen to screen the medium. The thickness of the collar is less than the thickness of the second flange. When the second flange is installed under the reactor, the surface of the connection position of the second flange and the reactor can be in close contact with each other, thereby preventing the medium from overflowing from the gap between the connection position of the second flange and the reactor, thereby avoiding leakage of the medium. By setting the first screen and the second screen, large-volume particulate matter in the medium can be filtered, which is helpful to improve the quality of the finished product of the outflowing medium.

[0019] When the turntable is rotated, the baffle and the scraper will also rotate together. The scraper can rotate close to the inner wall of the hollow tube, so as to remove the particles attached to the inner wall of the hollow tube. Both ends of the fan-shaped plate are provided with plug holes that penetrate up and down. The outer walls of the plug blocks are plugged into the inner walls of the plug holes at both ends of the fan-shaped plate, which fixes the fan-shaped plate and prevents the ball valve body on the discharge pipe at the top of the hollow tube from rotating. The movable rod inside the reset spring column is lifted upward, so that the plug block can be pulled out of the fan-shaped plate, and the fan-shaped plate can rotate at this time.
