Description

Technical Field

[0001] The present application relates to the technical field of valves, and in particular to a quick-release filter ball valve. Background Art

[0002] Ball valves are used to regulate and control fluids. The internal opening and closing parts (balls) are driven by the valve stem and rotate around the axis of the ball valve. There are many types of valves, such as ball valve bodies, relief valves, regulating valves, etc., which can be used to regulate and control fluids.

[0003] Both ends of the existing ball valve are equipped with flanges, which are used to connect to the pipeline through the flanges and bolts, and then the ball is driven to rotate by the valve stem to control the opening or closing of the entire pipeline and the flow rate of the liquid in the pipeline. When the pipeline transports sewage, the sewage contains impurities, which will clog the pipeline during long-term use. In order to facilitate the collection and cleaning of impurities in the sewage, a mounting shell is usually integrally formed on the shell of the ball valve, and a filter cylinder is installed in the mounting shell. The filter cylinder is tilted. When the pipeline transports sewage, the impurities in the sewage can be blocked by the filter cylinder, and then some of the impurities will adhere to the filter cylinder, and the other part will fall to the bottom of the mounting shell under the action of gravity, so that the impurities that fall to the bottom of the mounting shell can be cleaned through the sewage outlet.

[0004] In the above-mentioned related technologies, during the long-term use of the filter mesh cylinder, more and more impurities will be attached to the inner wall of the filter mesh cylinder, which will affect the passage of the entire sewage on the one hand, and on the other hand, when the impurities are completely attached to the filter mesh cylinder, water will not be able to pass through the entire filter mesh cylinder. At this time, the staff is required to disconnect the entire pipeline, and then open the installation shell to clean the impurities attached to the filter mesh cylinder, which will affect the water flow of the entire pipeline when the impurities on the filter mesh cylinder are cleaned. Utility Model Content

[0005] In order to not affect the water flow of the entire pipeline when cleaning impurities in the filter screen, the present application provides a quick-release filter ball valve.

[0006] The quick-release filter ball valve provided in this application adopts the following technical solution:

[0007] A quick-release filter ball valve comprises a ball valve body and a mounting shell arranged on the ball valve body, a filter screen cylinder is arranged in the mounting shell, a mounting ring is rotatably connected to the mounting shell, the mounting ring and the filter screen cylinder are arranged coaxially, and a cleaning rod is arranged on the mounting ring, the cleaning rod is arranged along the axial direction of the filter screen cylinder, and the cleaning rod abuts against the inner wall of the filter screen cylinder.

[0008] By adopting the above technical solution, during the use of the entire ball valve body, impurities will adhere to the inner wall of the filter screen cylinder. Then, when it is necessary to clean the impurities on the inner wall of the filter screen cylinder, the mounting ring is rotated diameterwise, and the mounting ring drives the cleaning rod to rotate, thereby cleaning the impurities on the inner wall of the filter screen cylinder. Therefore, it is not necessary to disconnect the entire pipeline during cleaning, and it will not affect the water flow of the entire pipeline, which makes it more convenient to use.

[0009] Optionally, a drain port for discharging impurities from the mounting shell is formed at one end of the mounting shell away from the ball valve body, and a sealing plate for sealing the drain port is threadedly connected to the mounting ring.

[0010] By adopting the above technical solution, when it is necessary to clean the impurities in the installation shell, the sealing plate is directly rotated to open the sewage outlet, and then the impurities in the installation shell are directly cleaned, so that it is more convenient to clean the impurities.

[0011] Optionally, a support rod is fixedly mounted on the sealing plate, and when the support rod is used to abut against the end surface of the filter screen cylinder, the support rod is used to support and limit the filter screen cylinder in the mounting shell.

[0012] By adopting the above technical solution, under the action of the support rod, the filter screen cartridge in the installation shell can be easily supported, thereby achieving the purpose of facilitating the installation and removal of the filter screen cartridge.

[0013] Optionally, a plurality of support rods are provided, and the plurality of support rods are spaced apart along the circumference of the sealing plate.

[0014] By adopting the above technical solution, under the action of multiple support rods, the supporting effect of the filter cylinder is better.

[0015] Optionally, one end of the support rod away from the sealing plate is rotatably connected to an abutment ball, and the abutment ball is used to abut against the end surface of the filter screen cylinder.

[0016] By adopting the above technical solution, since the abutment ball abuts against the end surface of the filter screen cylinder, the friction between the support rod and the filter screen cylinder can be reduced when the support rod rotates.

[0017] Optionally, the cleaning rod is fixedly mounted on the sealing plate, and when the sealing plate is separated from the mounting shell, the cleaning rod is also separated from the filter screen cartridge.

[0018] By adopting the above technical solution, since the cleaning rod is arranged on the sealing plate, when the filter screen cartridge needs to be replaced, the sealing plate needs to be removed. At this time, the sealing plate drives the support rod and the cleaning plate to separate from the mounting shell, thereby achieving the purpose of facilitating the replacement of the filter screen cartridge.

[0019] Optionally, both the outer surface of the mounting ring and the outer surface of the mounting shell are provided with a sliding groove, and a fixed block is slidably connected in the sliding groove. When the sealing plate needs to be installed or removed, the fixed block is placed in the sliding groove on the mounting ring and also in the sliding groove of the mounting shell. At this time, the mounting ring cannot rotate.

[0020] By adopting the above technical solution, when the sealing plate needs to be installed or removed, the fixing block is directly pushed so that the fixing block is in the slide grooves on the mounting ring and the mounting shell at the same time. At this time, the mounting ring is fixed on the mounting shell. When the mounting ring needs to be rotated, the fixing block is in the slide groove on the mounting ring. At this time, the rotation of the mounting ring can drive the sealing plate to rotate.

[0021] Optionally, a push rod is threadedly connected to the mounting ring, and the push rod moves on the mounting ring in a direction perpendicular to the axis of the filter cylinder, and one end of the push rod extends out of the outer side surface of the mounting ring. When the push rod extends out of the inner wall of the mounting ring and abuts against the cleaning rod, the mounting ring is rotated, and the mounting ring drives the cleaning rod to rotate on the sealing plate.

[0022] By adopting the above technical solution, when the filter cylinder is supported and fixed by the support rod, the push rod is rotated at this time, the push rod extends into the mounting shell and abuts against the side of the cleaning rod, and finally the mounting ring is directly rotated, and the mounting ring mobilizes the push rod and the support rod and the cleaning rod to rotate, so that the cleaning rod cleans the impurities in the filter cylinder.

[0023] Optionally, the ball valve body is provided with a quick-release assembly for connecting to a pipeline; the quick-release assembly includes a mounting cylinder slidably connected to the ball valve body and a plurality of abutment blocks sliding on the mounting cylinder, the mounting cylinder is used to be sleeved on the pipeline, the abutment block slides along an axis perpendicular to the mounting cylinder, and the plurality of abutment blocks are arranged at intervals along the circumference of the mounting cylinder, the ball valve body is provided with a second push spring for pushing the mounting cylinder to move away from the ball valve body, a push surface is provided on the ball valve body, and when the second push spring pushes the mounting cylinder to move away from the ball valve body, the push surface pushes the plurality of fixed blocks to abut against the surface of the pipeline to clamp and fix the pipeline.

[0024] By adopting the above technical solution, when the ball valve body is installed on the pipeline, the installation cylinder is directly pushed to move toward the ball valve body. At this time, the installation cylinder is sleeved on the pipeline. As the ball valve body moves, the installation sleeve is completely sleeved on the water pipe. Then the installation cylinder is released. Under the action of the second push spring, the installation cylinder and the abutment block on the installation cylinder are pushed to move away from the ball valve body at the same time. During the movement of the installation cylinder, the pushing surface pushes the abutment block to move toward the surface of the pipeline, thereby achieving clamping and fixing of the pipeline, which makes installation more convenient. When disassembly is required, the installation cylinder is directly pushed in the opposite direction to pull out the pipeline. BRIEF DESCRIPTION OF THE DRAWINGS

At the same time, a sliding groove 3 is provided on the outer side of the mounting ring 23, and a fixing block 31 is slidably connected in the sliding groove 3. The fixing block 31 slides along the axial direction of the mounting ring 23, and a sliding groove 3 is also provided on the outer shell. When the fixing block 31 is in the sliding groove 3 on the mounting shell 11 and the sliding groove 3 on the mounting ring 23 at the same time, the position of the mounting ring 23 is fixed, and it is convenient to rotate the sealing plate 22 at this time, so that the sealing plate 22 can be installed on the mounting ring 23 or detached from the mounting plate.

[0035] Reference Figure 3 and Figure 4 In this embodiment, the cross-sections of the fixed block 31 and the slide groove 3 are both set to a T-shaped structure, and the fixed block 31 is set in a rubber material. When the fixed block 31 is in the slide groove 3, the fixed block 31 is in an extruded deformation state, so that the fixed block 31 is not easy to slide and fall off when it is in the slide groove 3 on the mounting shell 11 and the slide groove 3 on the mounting ring 23 at the same time. In addition, in order to facilitate the movement of the fixed block 31, a push block 32 is bonded to the fixed block 31, and the push block 32 protrudes from the surface of the mounting ring 23, and an anti-slip pattern is set on the push block 32; at the same time, chamfers are set at both ends of the fixed block 31, and under the effect of the chamfers, it is easy for the fixed block 31 to move into the slide groove 3 on the mounting shell 11.

[0036] Reference Figure 3 and Figure 4 A plurality of support rods 4 are fixedly mounted on the sealing plate 22, and the plurality of support rods 4 are arranged at intervals along the circumference of the mounting ring 23, and abutment balls 41 are rotatably connected to the side of each support rod 4 away from the sealing plate 22, and the surface of the abutment balls 41 abuts against the end surface of the filter screen cylinder 2 away from the limiting ring 21, thereby fixing the position of the filter screen cylinder 2; at the same time, a cleaning rod 42 is fixedly mounted on the sealing plate 22, and the cleaning rod 42 is arranged along the axial direction of the filter screen cylinder 2, and the cleaning rod 42 is used to abut against the inner side surface of the filter screen cylinder 2, and at the same time The cleaning rod 42 is arranged obliquely on the inner side surface of the filter screen cylinder 2. When the inner wall of the filter screen cylinder 2 needs to be cleaned, the mounting ring 23 is directly rotated. The mounting ring 23 drives the sealing plate 22 and the support rod 4 and the cleaning rod 42 fixed on the sealing plate 22 to rotate. While the cleaning rod 42 rotates, the impurities attached to the inner wall of the filter screen cylinder 2 can be cleaned, thereby achieving the purpose of cleaning the impurities on the inner wall of the filter screen cylinder 2 without disconnecting the pipeline, thereby reducing the purpose of impurities clogging the filter screen cylinder 2.

[0037] Reference Figure 1 and Figure 5, a quick-release assembly 5 is provided on the ball valve body 1. Since both ends of the ball valve body 1 need to be connected to the pipeline, two quick-release assemblies 5 are provided on the ball valve body 1. Under the action of the quick-release assembly 5, it is easy to install and disassemble with the pipeline; the quick-release assembly 5 includes a mounting cylinder 51 slidably connected to the ball valve body 1, the mounting cylinder 51 is used to be sleeved on the surface of the pipeline, and a plurality of abutment blocks 52 are slidably connected to the mounting cylinder 51. The plurality of abutment blocks 52 are arranged at intervals along the circumference of the mounting cylinder 51, and the sliding direction of the abutment blocks 52 slides along a direction perpendicular to the axis of the mounting cylinder 51. At the same time, a pushing surface 6 is provided on the ball valve body 1, and one end of the abutment block 52 abuts on the pushing surface 6. When the mounting cylinder 51 is to be moved away from the ball valve body 1, under the action of the pushing surface 6, the plurality of abutment blocks 52 are pushed to move toward the axis of the mounting cylinder 51, thereby clamping and fixing the pipeline. At the same time, a sealing ring 61 is provided on the ball valve body 1, and the sealing ring 61 is used to be sleeved on the pipeline and used to seal the pipeline.

[0038] Reference Figure 1 and Figure 5 A second push spring 62 is arranged inside the ball valve body 1, one end of the second push spring 62 is arranged on the ball valve body 1, and the other end abuts on the end surface of the mounting tube 51. At the same time, the second push spring 62 is used to push the mounting tube 51 to move away from the ball valve body 1. When the pipeline needs to be fixed, the mounting tube 51 is pushed in the direction close to the ball valve body 1. At this time, the pushing surface 6 does not abut on the abutting block 52. The pipeline is directly inserted into the mounting tube 51, so that the sealing ring 61 is also sleeved on the pipeline, and then the mounting tube 51 is released. Under the action of the second push spring 62, the mounting tube 51 is pushed to move away from the ball valve body 1, so that the pushing surface 6 pushes the abutting block 52 to abut on the surface of the pipeline to achieve the fixation of the pipeline. Conversely, when disassembling, the mounting tube 51 can be removed from the mounting tube 51 by pushing it in the reverse direction.

[0039] The implementation principle of a quick-release filter ball valve in the embodiment of the present application is as follows: when the ball valve body 1 is used for a long time, when there are too many impurities attached to the inner wall of the filter screen cylinder 2, the mounting ring 23 is directly rotated, and the mounting ring 23 drives the sealing plate 22 and the cleaning rod 42 to rotate. During the rotation of the cleaning rod 42, the impurities on the inner wall of the filter screen cylinder 2 can be cleaned, and thus the impurities attached to the filter screen cylinder 2 can be cleaned without disconnecting the pipeline, which is more convenient during use.

[0040] Embodiment 2

[0041] The difference from the first embodiment is that a push rod 7 (not shown in the figure) is threadedly connected to the mounting ring 23, and the push rod 7 moves in a direction perpendicular to the axis of the mounting ring 23, and one end of the push rod 7 extends out of the outer side surface of the mounting ring 23. When the filter screen cartridge 2 needs to be installed or removed, the push rod 7 is directly placed in the mounting ring 23 without extending out of the inner side surface of the mounting ring 23. When the filter screen cartridge 2 is installed, the push rod 7 is directly rotated, and one end of the push rod 7 extends out to the inner side surface of the mounting ring 23 and abuts against the side surface of the support rod 4. At this time, it can be ensured that the rotating ring rotates while driving the sealing plate 22 and the support rod 4 to rotate at the same time, thereby preventing the rotating ring and the sealing plate 22 from rotating at different times.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
