When cleaning is required, simply remove the detachable filter cartridge, process it, and then reinstall it.

[0003] After searching, the Chinese patent publication number CN115920511B discloses a T-type filter, including an inlet pipe and an outlet pipe, and a filter pipe is arranged between the water inlet pipe and the outlet pipe, the port of the filter pipe is fixed with a cover plate through a connecting plate, a filter cartridge is arranged on the cover plate, the filter cartridge is inserted into the filter pipe, the filter cartridge includes an outer layer and an inner layer, the outer layer is connected to the cover plate through a connecting piece, a sliding hole is opened at the bottom of the outer layer and the sliding hole is connected to the filter hole on the filter cartridge, the inner layer is inserted and slides in the sliding hole, a lifting assembly is arranged between the inner layer and the cover plate, and a push-sweeping assembly is arranged between the connecting plate and the filter pipe.

[0004] The above patent has the following deficiencies: it does not have the ability to resist impact. When the water pressure on the water inlet side suddenly increases and generates impact force, the filter will be affected by the force of the water flow and will also bear the impact force, causing the filter to deform and be damaged.

[0005] To this end, the present invention proposes a T-type filter based on impact protection. Summary of the Invention

[0006] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a T-type filter based on impact protection.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A T-type filter based on impact protection, comprising a "T"-shaped tube,

[0009] The three end faces of the "T"-shaped tube are all fixed with connecting flange 1, and one of the connecting flanges 1 of the "T"-shaped tube is connected to an opening ball valve through connecting flange 2, an opening control mechanism is provided on one side of the opening ball valve, and an impact-resistant filter assembly for filtering is provided on the top of the connecting flange 2;

[0010] The impact-resistant filter assembly includes a hollow outer cylinder fixed to a second connecting flange and a hollow inner cylinder rotatably connected to the inner wall of the hollow outer cylinder. The side wall of the hollow outer cylinder is provided with a uniform waist-shaped hole 1, and the side wall of the hollow inner cylinder is provided with a uniform waist-shaped hole 2. The waist-shaped hole 1 and the waist-shaped hole 2 cooperate with each other to form a filter hole.

[0011] Preferably, a fixed plate is fixedly embedded in the inner wall of the second connecting flange, and a movable plate is slidably connected to the bottom of the hollow inner cylinder via a guide rod.

[0012] Furthermore: a first through hole is opened on the inner wall of the fixed plate, and a second through hole is opened on the inner wall of the movable plate, and the projections of the first through hole and the second through hole in the vertical direction do not overlap with each other.

[0013] Based on the above solution: a spring 1 is provided on the outer wall of the guide rod.

[0014] A better solution among the above solutions is: a spiral groove 1 is opened on the inner wall of the hollow outer cylinder, a limiting protrusion 1 is fixed on the outer wall of the movable plate, and the limiting protrusion 1 is movably limited and matched with the inner wall of the spiral groove 1.

[0015] As a further solution of the present invention: the opening ball valve includes a shell and a ball core rotatably connected to the inner wall of the shell through a valve stem, and a flow channel is opened on the inner wall of the ball core.

[0016] At the same time, a guide shell is fixed on the top of the shell, and a movable block is slidably connected to the inner wall of the guide shell. A spiral groove 2 is opened on the outer wall of the valve stem, and a limiting protrusion 2 that cooperates with the spiral groove 2 is fixed on the inner wall of the movable block.

[0017] As a preferred embodiment of the present invention: the inner wall of the guide shell is slidingly connected to a limiting arc head boss, the limiting arc head boss is used to limit the movable block, and when the movable block contacts the limiting arc head boss, the opening of the flow channel is maximum, and the limiting arc head boss is connected to the guide shell through spring three.

[0018] At the same time, the opening control mechanism includes a cylinder body fixed to the end of the guide shell and a piston slidably connected to the inner wall of the cylinder body. The bottom of the piston is connected to the movable block through a connecting rod. The top of the piston is buckled with spring 2, and the other end of spring 2 is buckled to the inner wall of the cylinder body.

[0019] As a more preferred solution of the present invention: the top of the cylinder is connected to a connecting pipe, and the other end of the connecting pipe is connected to the water inlet side of the shell.

[0020] The beneficial effects of the present invention are:

[0021] 1. The present invention provides an impact-resistant filter assembly as a combination of a hollow outer cylinder and a hollow inner cylinder. The rotation of the hollow inner cylinder can change the size of the filter holes, thereby increasing the area of ​​the filter holes and reducing the blocking effect on the water flow when the filter is impacted, thereby reducing the force of the water flow, reducing the impact force, and preventing the hollow outer cylinder and the hollow inner cylinder from being damaged.

[0022] 2. The present invention, by providing a movable plate and a fixed plate as well as a spiral groove and a limiting protrusion, utilizes the barrier effect of the movable plate on the water flow and the linear transmission characteristics of the impact. On the one hand, the movable plate can absorb part of the impact force. On the other hand, the displacement characteristic of the movable plate in absorbing the impact force can be utilized to enable the automatic rotation of the hollow inner cylinder, thereby realizing automatic anti-impact control.

[0023] 3. The present invention sets an opening ball valve. When the water pressure on the water inlet side increases, the movable block can be controlled to descend, thereby utilizing the limiting effect of the second limiting protrusion and the second spiral groove to make the valve stem drive the ball core to rotate, thereby reducing the opening of the flow channel. At this time, reducing the flow cross-sectional area will resist the impact to a certain extent and prevent it from being transmitted to the downstream.

[0024] 4. The present invention, on the basis of setting the opening to resist impact, drives the movable block through a piston, and the power of the piston comes from the water pressure on the water inlet side, so that after an impact occurs on the water inlet side, the flow channel opening is automatically reduced, achieving an automated control process.

[0033] The technical solution of the present invention will be further described in detail below in conjunction with specific implementation methods.

[0034] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0035] Example 1:

[0036] A T-type filter based on impact protection, such as Figure 1-Figure 7 As shown, it includes a "T"-shaped tube 1, and the three end faces of the "T"-shaped tube 1 are fixed with connecting flanges 1 2, and one of the connecting flanges 1 2 of the "T"-shaped tube 1 is connected to an opening ball valve 4 through a connecting flange 2 3, an opening control mechanism 5 is provided on one side of the opening ball valve 4, and an impact-resistant filter component 6 for filtering is provided on the top of the connecting flange 2 3.

[0037] The impact-resistant filter assembly 6 includes a hollow outer cylinder 7 fixed to the connecting flange 2 3 and a hollow inner cylinder 8 rotatably connected to the inner wall of the hollow outer cylinder 7. The side wall of the hollow outer cylinder 7 is provided with a uniform waist-shaped hole 1 9, and the side wall of the hollow inner cylinder 8 is provided with a uniform waist-shaped hole 2 10. The waist-shaped hole 1 9 and the waist-shaped hole 2 10 cooperate with each other to form a filter hole 11.

[0038] When the device is in use, the filter hole 11 formed between the waist-shaped hole 1 9 and the waist-shaped hole 2 10 can be used for filtering. Waste water enters from the bottom of the open ball valve 4, and then enters the interior of the hollow outer cylinder 7 and the hollow inner cylinder 8. It is filtered when flowing through the filter hole 11, and then flows out through both sides of the "T"-shaped tube 1. When the water pressure on the water inlet side increases and is impacted, the hollow inner cylinder 8 will rotate, thereby increasing the overlapping area of ​​the waist-shaped hole 1 9 and the waist-shaped hole 2 10, and the area of ​​the filter hole 11 increases, reducing the blocking effect on the water flow.

[0039] This device, by setting the impact-resistant filter component 6 as a combination of a hollow outer cylinder 7 and a hollow inner cylinder 8, can change the size of the filter hole 11 by rotating the hollow inner cylinder 8, so that when it is impacted, the area of ​​the filter hole 11 can be increased, reducing the blocking effect on the water flow, thereby reducing the force of the water flow, reducing the impact force, and preventing the hollow outer cylinder 7 and the hollow inner cylinder 8 from being damaged.

[0040] In order to solve the problem of automatic driving; Figure 3 、 4 As shown, a fixed plate 15 is fixedly embedded in the inner wall of the second connecting flange 3 , and a movable plate 14 is slidably connected to the bottom of the hollow inner cylinder 8 through a guide rod 12 .

[0041] The inner wall of the fixed plate 15 is provided with a first through hole 16 , and the inner wall of the movable plate 14 is provided with a second through hole 17 . The projections of the first through hole 16 and the second through hole 17 in the vertical direction do not overlap with each other.

[0042] The outer wall of the guide rod 12 is sleeved with a spring 13 .

[0043] The inner wall of the hollow outer cylinder 7 is provided with a spiral groove 18 , and the outer wall of the movable plate 14 is fixed with a limiting protrusion 19 , which is movable and limitedly fitted on the inner wall of the spiral groove 18 .

[0044] When no water flows through, the movable plate 14 moves downward under the elastic force of the spring 13, and the movable plate 14 fits with the fixed plate 15 to achieve end face sealing. When water flows through, the movable plate 14 will be moved upward by the water flow pressure, thereby entering the hollow inner cylinder 8 through the through hole 16, the through hole 2 17 and the gap between the movable plate 14 and the fixed plate 15. When the pressure on the water inlet side suddenly increases and the pressure is gradually transmitted along the direction of the water flow, when it is transmitted to the position of the movable plate 14, the movable plate 14 will also be impacted and moved upward, thereby driving the movable plate 14 to rotate through the cooperation of the spiral groove 18 and the limiting protrusion 19, causing the hollow inner cylinder 8 to rotate, thereby increasing the area of ​​the filter hole 11.

[0045] This device, by providing a movable plate 14 and a fixed plate 15, a spiral groove 18 and a limiting protrusion 19, utilizes the barrier effect of the movable plate 14 on the water flow and the characteristic of linear transmission of impact. On the one hand, the movable plate 14 can absorb part of the impact force. On the other hand, the displacement characteristic of the movable plate 14 in absorbing the impact force can be utilized to enable the automatic rotation of the hollow inner cylinder 8, thereby realizing automatic anti-impact control.

[0046] In order to solve the opening control problem; Figure 5 As shown, the opening ball valve 4 includes a shell 20 and a ball core 21 rotatably connected to the inner wall of the shell 20 through a valve stem 22 , and a flow channel 30 is opened on the inner wall of the ball core 21 .

[0047] A guide shell 24 is fixed on the top of the shell 20, and a movable block 23 is slidably connected to the inner wall of the guide shell 24. A spiral groove 24 is opened on the outer wall of the valve stem 22, and a limiting protrusion 23 is fixed on the inner wall of the movable block 23 to cooperate with the spiral groove 24 for movable limiting.

[0048] When the water pressure on the water inlet side increases, the flow rate is directly accelerated. If the flow cross-sectional area is reduced at this time, the impact will be resisted to a certain extent to prevent it from being transmitted to the downstream. Therefore, when the water pressure on the water inlet side increases, the movable block 23 can be controlled to descend, so that the limiting effect of the limiting protrusion 23 and the spiral groove 24 can be utilized to make the valve stem 22 drive the ball core 21 to rotate, thereby reducing the opening of the flow channel 30.

[0049] This device is provided with an opening ball valve 4. When the water pressure on the water inlet side increases, the movable block 23 can be controlled to descend, thereby utilizing the limiting effect of the limiting protrusion 33 and the spiral groove 34 to allow the valve stem 22 to drive the ball core 21 to rotate, thereby reducing the opening of the flow channel 30. At this time, reducing the flow cross-sectional area will resist the impact to a certain extent and prevent it from being transmitted to the downstream.

[0050] When the present embodiment is in use, the filter hole 11 formed between the waist-shaped hole 19 and the waist-shaped hole 2 10 can be used for filtering. Waste water enters from the bottom of the open ball valve 4, and then enters the interior of the hollow outer cylinder 7 and the hollow inner cylinder 8. It is filtered when flowing through the filter hole 11, and then flows out through both sides of the "T"-shaped tube 1. When the water pressure on the water inlet side increases and is impacted, the hollow inner cylinder 8 will rotate, thereby increasing the overlapping area of ​​the waist-shaped hole 19 and the waist-shaped hole 2 10, and the area of ​​the filter hole 11 increases, reducing the blocking effect on the water flow. When no water flows through, the movable plate 14 moves downward under the elastic force of the spring 13, and the movable plate 14 fits with the fixed plate 15 to achieve end face sealing. When water flows through, the movable plate 14 will move upward under the pressure of the water flow, thereby utilizing the through hole 16, the through hole 2 17 and the movable plate 14 and the fixed plate 15 enter the hollow inner cylinder 8. When the pressure on the water inlet side suddenly increases, and the pressure will gradually be transmitted along the direction of water flow, when it is transmitted to the position of the movable plate 14, the movable plate 14 will also be impacted and move upward, thereby driving the movable plate 14 to rotate through the cooperation of the spiral groove 18 and the limiting protrusion 19, so that the hollow inner cylinder 8 rotates, increasing the area of ​​the filter hole 11. At the same time, since the water pressure on the water inlet side increases, it directly leads to an increase in the flow rate. If the flow cross-sectional area is reduced at this time, the impact will be resisted to a certain extent to prevent it from being transmitted to the downstream. Therefore, when the water pressure on the water inlet side increases, the movable block 23 can be controlled to descend, thereby utilizing the limiting effect of the limiting protrusion 2 33 and the spiral groove 2 34 to make the valve stem 22 drive the ball core 21 to rotate, thereby reducing the opening of the flow channel 30.

[0051] Example 2:

[0052] A T-type filter based on impact protection, such as Figure 1 As shown, in order to solve the problem of automatic control of the opening; this embodiment makes the following improvements on the basis of embodiment 1: the inner wall of the guide shell 24 is slidably connected with a limiting arc head boss 32, the limiting arc head boss 32 is used to limit the movable block 23, and when the movable block 23 contacts the limiting arc head boss 32, the opening of the flow channel 30 is the largest, and the limiting arc head boss 32 is connected to the guide shell 24 through spring three 31.

[0053] The opening control mechanism 5 includes a cylinder 27 fixed to the end of the guide shell 24 and a piston 26 slidably connected to the inner wall of the cylinder 27. The bottom of the piston 26 is connected to the movable block 23 through a connecting rod 25. The top of the piston 26 is buckled with a spring 28, and the other end of the spring 28 is buckled to the inner wall of the cylinder 27.

[0054] A connecting pipe 29 is connected to the top of the cylinder body 27 , and the other end of the connecting pipe 29 is connected to the water inlet side of the housing 20 .

[0055] When this embodiment is in use, when water enters the water inlet side of the housing 20, the water pressure of the inlet water will also be transmitted to the inner cavity of the cylinder body 27, thereby causing the piston 26 to move downward until it moves down to the movable block 23 and fits with the limiting arc head boss 32. At this time, the flow channel 30 is opened to the maximum. When an impact occurs on the water inlet side, the impact will also be transmitted to the inner cavity of the cylinder body 27, causing the water pressure on the piston 26 to increase suddenly. Then the movable block 23 overcomes the resistance of the limiting arc head boss 32 and moves downward, thereby causing the ball core 21 to rotate excessively, reducing the opening of the flow channel 30.

[0056] This device, on the basis of setting the opening to resist impact, drives the movable block 23 through the piston 26, and the power of the piston 26 comes from the water pressure on the water inlet side, so that after an impact occurs on the water inlet side, the opening of the flow channel 30 is automatically reduced, achieving an automated control process.

[0057] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
