Technical Field

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

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters of the conveying medium. There are many types of valves, such as gate valves, overflow valves, regulating valves, etc.

[0003] The existing traditional gate valve includes a gate valve body and flanges arranged at both ends of the gate valve body. The flange is provided with a mounting hole, and bolts are inserted into the mounting hole. The bolts are connected to the flange on the water pipe, thereby realizing the installation of the gate valve between the two pipes, and the opening of the gate valve controls the opening of the entire pipe. However, during the water flow of the pipe, in order to reduce impurities at the outlet, a filter assembly is installed in the gate valve body. The filter assembly includes a mounting shell, and the mounting shell and the gate valve body are integrally formed. A filter screen is arranged in the mounting shell. After the water at the water inlet passes through the filter screen, part of the impurities will be blocked by the filter screen, thereby achieving the purpose of filtering the water.

[0004] In the above-mentioned related technologies, during long-term use, some impurities will be adsorbed on the inner wall of the filter cylinder, affecting the water flow rate of the entire pipeline. At this time, the staff is required to open the installation shell, and then remove the filter from the installation shell for cleaning. During the process of cleaning the filter cylinder, the entire pipeline needs to be in a water-free state, which will affect the water supply efficiency of the entire pipeline. Utility Model Content

[0017] Optionally, a pushing rod is slidably connected to the connecting rod, the pushing rod is fixedly mounted on the fixing block, and the pushing rod is arranged along the length direction of the fixing rod.

DETAILED DESCRIPTION

[0028] The following is combined with Figure 1-4 This application is described in further detail.

[0029] The present application embodiment discloses a quick-release filter gate valve. Figure 1 A quick-release filter gate valve comprises a gate valve body 1, on which a filter assembly 2 is arranged, and the filter assembly 2 is used for filtering water passing through the gate valve body 1, thereby reducing impurities in the water at the outlet end.

[0030] Reference Figure 1 and Figure 2 The filter assembly 2 includes an outer shell 21 and a filter screen cartridge 22. The outer shell 21 and the gate valve body 1 are integrally formed, and the outer shell 21 is tilted below the gate valve body 1. In this embodiment, the outer shell 21 is configured as a cylindrical structure, and one end of the outer shell 21 away from the gate valve body 1 is configured as an opening, which is convenient for installing the filter screen cartridge 22 in the outer shell 21 and also convenient for taking the filter screen cartridge 22 out of the outer shell 21. The filter screen cartridge 22 and the outer shell 21 are coaxially configured, and a limiting ring is configured in the gate valve body 1. The filter screen cartridge 22 is used to abut against the limiting ring. A blocking plate 11 is configured on the outer shell 21. The blocking plate 11 is threadedly connected to the outer shell 21, and the blocking plate 11 is used to block the opening on the outer shell 21.

[0031] Reference Figure 1 and Figure 2 When the filter screen cartridge 22 is installed in the shell 21, one side of the filter screen cartridge 22 is connected to the inside of the gate valve body 1, and the other side abuts against the inner wall of the shell 21. At this time, the part that is connected to the filter screen cartridge 22 and the gate valve body 1 plays a filtering role. In this embodiment, in the initial state, the part that is connected to the inside of the filter screen cartridge 22 and the gate valve body 1 is defined as the first contact surface 12, that is, the part used to filter impurities, and the other side abutting against the inner wall of the shell 21 is defined as the second contact surface 13.

[0032] Reference Figure 2 and Figure 3A fixing rod 14 is provided on the blocking plate 11, and the fixing rod 14 is rotatably connected to the blocking plate 11, and one end of the fixing rod 14 extends out of the blocking plate 11, and the other end is in the housing 21. The end of the fixing rod 14 extending into the housing 21 is provided with a mounting assembly 3, and the fixing rod 14 is fixedly connected to the filter screen cylinder 22 through the mounting assembly 3. Since the filter screen cylinder 22 is fixed on the fixing rod 14, when the first contact surface 12 is adsorbed by impurities, the water passing efficiency of the entire gate valve body 1 will decrease. At this time, by rotating the fixing rod 14, the fixing rod 14 can drive the filter screen cylinder 22 to rotate, so that the second contact surface 13 and the first contact surface 12 can exchange positions. At this time, the first contact surface 12 adsorbed by impurities abuts against the inner wall of the housing 21, and the second contact surface 13 continues to filter water.

[0033] Reference Figure 2 and Figure 3 In addition, a fixing nut 15 is threadedly connected to the fixing rod 14, and the fixing nut 15 is used to abut against the end face of the blocking plate 11. When the fixing rod 14 and the filter screen cylinder 22 need to be fixed in position, the fixing nut 15 is directly rotated to make the fixing nut 15 abut against the blocking plate 11.

One end of the fixing spring 44 is fixedly installed on the fixing block 32, and the other end is fixed on the connecting rod 31. At the same time, a fixing groove 4 is opened on the inner wall of the filter screen cylinder 22. When the filter screen cylinder 22 is fixed, the fixing groove 4 and the fixing block 32 are made to correspond. Then, under the action of the fixing spring 44, the fixing block 32 is pushed to move into the fixing groove 4, thereby fixing the filter screen cylinder 22. When the fixing block 32 moves into the fixing groove 4, the fixing rod 14 is rotated, and the fixing rod 14 can drive the filter screen cylinder 22 to rotate. In addition, in order to facilitate the installation of the filter screen cylinder 22 on the connecting rod 31, a plurality of fixing grooves 4 are opened on the inner wall of the filter screen cylinder 22, and the plurality of fixing grooves 4 are arranged at intervals along the circumference of the filter screen cylinder 22.

[0035] Reference Figure 2 and Figure 3 A push rod 41 is fixedly installed on the fixed block 32. The push rod 41 is arranged in a length direction perpendicular to the fixed rod 14, and the push rod 41 is also slidably connected to the connecting rod 31. When the filter screen cartridge 22 needs to be replaced, the fixed block 32 is directly driven to disengage from the fixed groove 4 through the push rod 41. At this time, the fixed spring 44 is in a compressed state, thereby achieving the purpose of facilitating the replacement of the filter screen cartridge 22.

[0036] Reference Figure 2 and Figure 3 A cleaning assembly 5 is provided on the sealing plate 11. The cleaning assembly 5 is used to clean the impurities on the inner wall of the filter screen cylinder 22. The cleaning assembly 5 includes a mounting plate 51 and a cleaning plate 52. A mounting ring 42 is fixedly mounted on the mounting plate 51. The outer surface of the mounting ring 42 abuts against the inner wall of the outer shell 21. At the same time, one end face abuts against the end face of the filter screen cylinder 22, and the other end face abuts against the sealing plate 11. When the sealing plate 11 is completely threadedly connected to the outer shell 21, the sealing plate 11 presses and fixes the mounting ring 42 to clean The plate 52 is slidably connected to the mounting plate 51, and the cleaning plate 52 is arranged along the length direction of the housing 21. A pusher 43 is arranged on the mounting plate 51, and the pusher 43 is used to push the cleaning plate 52 to abut against the inner wall of the filter screen cylinder 22. In this embodiment, the pusher 43 is arranged as a push spring, one end of the push spring is fixed on the mounting plate 51, and the other end is fixedly mounted on the cleaning plate 52, so that when the filter screen cylinder 22 is rotated, the cleaning plate 52 can scrape and clean the impurities adsorbed on the inner wall of the filter screen cylinder 22. In addition, when there is a certain amount of impurities in the housing 21, the blocking plate 11 is directly rotated to open the opening on the housing 21, so as to facilitate the cleaning of the impurities in the housing 21.

[0037] Reference Figure 1 and Figure 4 , a quick-release assembly 6 is provided on the gate valve body 1. Since both ends of the gate valve body 1 need to be connected to the pipeline, two quick-release assemblies 6 are provided on the gate valve body 1. Under the action of the quick-release assembly 6, it is convenient to install and disassemble with the pipeline; the quick-release assembly 6 includes a mounting cylinder 61 slidably connected to the gate valve body 1, the mounting cylinder 61 is used to be sleeved on the surface of the pipeline, and a plurality of abutment blocks 62 are slidably connected to the mounting cylinder 61. The plurality of abutment blocks 62 are arranged at intervals along the circumference of the mounting cylinder 61, and the sliding direction of the abutment blocks 62 slides along a direction perpendicular to the axis of the mounting cylinder 61. At the same time, a pushing surface 7 is provided on the gate valve body 1, and one end of the abutment block 62 abuts on the pushing surface 7. When the mounting cylinder 61 is to be moved away from the gate valve body 1, under the action of the pushing surface 7, the plurality of abutment blocks 62 are pushed to move toward the axis of the mounting cylinder 61, thereby clamping and fixing the pipeline. At the same time, a sealing ring 8 is provided on the gate valve body 1, and the sealing ring 8 is used to be sleeved on the pipeline and used to seal the pipeline.

At the same time, the second push spring 71 is used to push the mounting tube 61 to move away from the gate valve. When the pipeline needs to be fixed, the mounting tube 61 is pushed toward the gate valve body 1. At this time, the pushing surface 7 does not abut against the abutting block 62. The pipeline is directly inserted into the mounting tube 61, so that the sealing ring 8 is also sleeved on the pipeline, and then the mounting tube 61 is released. Under the action of the second push spring 71, the mounting tube 61 is pushed to move away from the gate valve body 1, so that the pushing surface 7 pushes the abutting block 62 to abut against the surface of the pipeline to fix the pipeline. Conversely, when disassembling, the mounting tube 61 can be removed from the mounting tube 61 by pushing it in the reverse direction.

[0039] The implementation principle of a quick-release filter gate valve in an embodiment of the present application is as follows: when filtering water, when impurities are adsorbed on the first contact surface 12, the water flow through the first contact surface 12 will become smaller, and then the fixing nut 15 is rotated so that the fixing nut 15 no longer abuts the blocking plate 11, and then the fixing rod 14 is rotated. The fixing rod 14 drives the filter mesh cylinder 22 to rotate, so that the second contact surface 13 contacts the water in the gate valve body 1, and the second contact surface 13 abuts on the inner wall of the outer shell 21. At this time, the water flow in the entire gate valve body 1 returns to normal, so that there is no need to close the entire pipeline when cleaning impurities.

[0040] 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.
