Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a high-pressure ball valve with filtering. Background Art

[0002] A high-pressure ball valve is a switch that cuts off a pipeline. The interior of the high-pressure ball valve is equipped with components such as a valve seat and a rotating shaft. By controlling the rotation of the rotating shaft, the valve seat can be driven to block the medium inside the high-pressure ball valve, and the flow of the medium inside two sets of connected pipelines can be controlled. It is widely used in industries such as chemical, papermaking, and electric power.

[0003] Different medium circulation requires the selection of different high-pressure ball valves. In the case of impurities inside the medium, a high-pressure ball valve equipped with a filter plate will be selected. These high-pressure ball valves can filter some impurities through the internal filter plate to ensure the purity of the medium in the next pipeline. The filter plate is usually fixedly installed at the inlet end of the high-pressure ball valve, and the circumferential position of the filter plate is connected to the inlet of the high-pressure ball valve through multiple sets of fixing bolts. Since the impact force of the medium inside the high-pressure ball valve is relatively large, after the filter plate has been used for a period of time, the filter plate will be deformed and the filtering capacity will be reduced due to the impact of the medium. The filter plate needs to be replaced. When replacing, the high-pressure ball valve needs to be disconnected from the connecting pipe and the multiple sets of fixing bolts need to be removed by tools. After replacing the new filter plate, the connecting pipe is connected to the ball valve. It is very troublesome to use. In order to solve this technical problem, the utility model proposes a high-pressure ball valve with filtration. Utility Model Content

A filter plate 5 is installed on one side of the connecting plate 4. The connecting plate 4 can move linearly inside the limit plate 3. When the filter plate 5 is installed, it can ensure that the filter plate 5 is vertically installed inside the fixed shell 2 to avoid the filter plate 5 from tilting during installation.

[0025] A sealing cover 6 is slidably connected to the upper surface of the fixed shell 2, and the upper part of the fixed shell 2 can be sealed by the sealing cover 6. When the filter plate 5 is replaced, the sealing cover 6 can be opened to take out the filter plate 5 for replacement without disconnecting the ball valve body 1 and the connecting pipe. A sealing plate 15 is fixedly installed on the lower surface of the sealing cover 6, and a plurality of groups of positioning rods 16 are fixedly installed on the outer surface of the sealing plate 15. The outer surfaces of the plurality of groups of positioning rods 16 are slidably connected to the inner wall of the fixed shell 2, and the outer surfaces of the plurality of groups of positioning rods 16 are slidably connected to the outer surface of the limit plate 3. By setting a plurality of groups of positioning rods 16, it is possible to ensure that the various positions of the sealing plate 15 and the sealing cover 6 move up and down synchronously, avoid tilting of a single position of the sealing cover 6, and ensure that the various ends of the sealing cover 6 move synchronously.

[0026] A support rod 13 is fixedly installed on the inner wall of the limit plate 3, and the outer surface of the support rod 13 is slidably connected to the inside of the connecting plate 4. A spring 14 is sleeved on the outside of the support rod 13, and the spring 14 can be auxiliary fixed by the support rod 13 to ensure the stability of the spring 14 when in use. One end of the spring 14 is connected to the inner wall of the limit plate 3, and the other end of the spring 14 contacts the inner wall of the connecting plate 4. When the sealing cover 6 is opened, the spring 14 can push the connecting plate 4 to move. At this time, the filter plate 5 can be controlled to move toward the inside of the fixed shell 2, which is convenient for the staff to replace it.

[0027] Both ends of the sealing cover 6 are connected to multiple groups of fixed shafts 7, and the outer surface of the fixed shaft 7 is rotatably connected to a fixed plate 8, which can drive the fixed shaft 7 to move, and can seal the upper end of the sealing cover 6 to the fixed shell 2.

The movement of the moving block 10 can be limited by the clamping plates 17, and the moving block 10 can be controlled to move up and down in a straight line inside the limiting plate 12 to ensure the stability of the moving block 10 when moving. A rotating handle 18 is connected to one end of the threaded rod 11, and the rotation of the threaded rod 11 can be controlled by rotating the handle 18, and no additional tools are needed when replacing the filter plate 5.

The rotation of the threaded rod 11 can control the moving block 10 to slide inside the limit plate 2 12. At this time, the moving block 10 will drive one end of the fixed plate 8 to move and push the sealing cover 6 up through the fixed plate 8. When the moving block 10 moves to the upper position of the limit plate 2 12, the sealing cover 6 is disengaged from the fixed shell 2. At this time, the connecting plate 4 will be pushed out of the limit plate 3 under the action of the spring 14, and the filter plate 5 can be replaced at this time. When replacing the filter plate 5, the connecting plate 4 is installed along the direction of the support rod 13, and the sealing cover 6 is vertically placed into the fixed shell 2 through the sealing plate 15 and the positioning rod 16. The threaded rod 11 is rotated to drive the moving block 10 to move downward, and the moving block 10 controls the fixed plate 8 to be fixed with the sealing cover 6.
