Description

Technical Field

[0001] The utility model relates to the technical field of one-way valves, in particular to a one-way valve filtering device. Background Art

[0002] In fluid transmission and control systems, the primary function of a check valve is to allow fluid to flow freely in one direction while preventing it from flowing in the opposite direction. However, in practical applications, fluids often contain impurities and particulate matter. These impurities can become lodged within the check valve as it flows through it, affecting its proper opening and closing, or even causing it to fail. Therefore, integrating a filter into the check valve to pre-treat the fluid and remove impurities is crucial for ensuring its long-term, stable operation.

[0003] Currently, the filter device of the one-way valve needs to be cleaned or replaced after long-term use to ensure subsequent filtration efficiency. However, the disassembly and assembly of the filter device is relatively cumbersome, consumes a lot of time and energy, and is not practical enough.

[0004] In view of the above problems, the utility model proposes a one-way valve filtering device. Utility Model Content

[0005] The purpose of the utility model is to provide a one-way valve filtering device, in which a middle connecting block is threadedly connected to the outer wall of a threaded rod, the end of the middle connecting block away from the threaded rod is fixedly connected to the second connecting plate, the inner wall of one end of the threaded rod is slidingly connected to an inner connecting column, the inner connecting column is rotatably connected to the second connecting plate, and the end of the middle connecting block away from the threaded rod is fixedly connected to the first positioning rod and the second positioning rod, thereby solving the problems in the background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a one-way valve filter device, comprising a valve body, and a first receiving plate mounted on one end of the valve body, a second receiving plate being provided at one end of the first receiving plate, a filter cartridge being mounted at an end of the second receiving plate close to the first receiving plate, and a control assembly being mounted at an end of the second receiving plate away from the filter cartridge, the control assembly comprising a control handle and a threaded rod, the control handle being fixedly connected to the threaded rod;

[0007] The outer wall of the threaded rod is threadedly connected to a middle connecting block, and the end of the middle connecting block away from the threaded rod is fixedly connected to the second connecting plate. The inner wall of one end of the threaded rod is slidably connected to an inner connecting column, and the inner connecting column is rotatably connected to the second connecting plate. The end of the middle connecting block away from the threaded rod is fixedly connected to the first positioning rod and the second positioning rod.

[0008] Furthermore, two groups of connection slot bodies are respectively formed inside the first connection plate and the second connection plate, and positions of the two groups of connection slot bodies correspond to positions of the first positioning rod and the second positioning rod respectively.

[0009] Furthermore, the first positioning rod and the second positioning rod are symmetrically distributed about the center of the middle connecting block.

[0010] Furthermore, the middle connecting block has a T-shaped structure.

[0011] Furthermore, a reinforcement block A and a reinforcement block B are fixedly connected to both sides of the first positioning rod and the second positioning rod, respectively, and the reinforcement block A and the reinforcement block B are symmetrically distributed about the center of the second positioning rod.

[0012] Furthermore, the reinforcement block A and the reinforcement block B are both components made of rubber material.

[0013] Furthermore, when the reinforcement block A and the reinforcement block B are in the cavity of the connection slot body, the reinforcement block A and the reinforcement block B are both in a compressed state.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] The utility model proposes a one-way valve filter device, which rotates a control handle and utilizes the control handle to drive the threaded rod to rotate. The threaded rod drives the middle connecting block to move outward on the outer wall of the threaded rod itself through the cooperation of the internal connecting column, so that the second connecting plate gradually moves away from the first connecting plate, driving the first positioning rod and the second positioning rod to gradually separate from the first connecting plate, thereby removing the filter cartridge from the inner wall of the valve body, making it easy to clean and replace. This solves the problem that the filter device of the one-way valve needs to be cleaned or replaced after long-term use, thereby ensuring the subsequent filtering efficiency. However, the disassembly and assembly operations of the filter device are relatively cumbersome, consume a lot of time and energy, and lack practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1-4 In order to solve the problem that the filter device of the one-way valve needs to be cleaned or replaced after long-term use to ensure the subsequent filtering efficiency, however, the disassembly and assembly of the filter device is relatively cumbersome, time-consuming and labor-intensive, and lacks practicality, the following preferred technical solutions are provided:

[0023] A one-way valve filtering device comprises a valve body 1 and a first receiving disc 2 installed at one end of the valve body 1, a second receiving disc 3 is provided at one end of the first receiving disc 2, a filter cartridge 4 is installed at one end of the second receiving disc 3 close to the first receiving disc 2, and a control component 5 is installed at one end of the second receiving disc 3 away from the filter cartridge 4. The control component 5 comprises a control handle 51 and a threaded rod 52, the control handle 51 is fixedly connected to the threaded rod 52, the outer wall of the threaded rod 52 is threadedly connected with a middle connecting block 53, the end of the middle connecting block 53 away from the threaded rod 52 is fixedly connected to the second receiving disc 3, the inner wall of one end of the threaded rod 52 is slidably connected with an inner connecting column, the inner connecting column is rotatably connected to the second receiving disc 3, and the end of the middle connecting block 53 away from the threaded rod 52 is fixedly connected to the first positioning rod 54 and the second positioning rod 55. Two sets of connecting groove bodies 6 are opened in the interior of the first receiving disc 2 and the second receiving disc 3, and the positions of the two sets of connecting groove bodies 6 correspond to the positions of the first positioning rod 54 and the second positioning rod 55 respectively.

[0024] The first positioning rod 54 and the second positioning rod 55 are symmetrically distributed about the center of the middle connecting block 53, and the middle connecting block 53 has a T-shaped structure. The first positioning rod 54 and the second positioning rod 55 are respectively fixedly connected with reinforcement blocks A7 and reinforcement blocks B8 on both sides. The reinforcement blocks A7 and reinforcement blocks B8 are symmetrically distributed about the center of the second positioning rod 55. The reinforcement blocks A7 and reinforcement blocks B8 are both components made of rubber material. When the reinforcement blocks A7 and reinforcement blocks B8 are in the cavity of the connecting groove body 6, the reinforcement blocks A7 and reinforcement blocks B8 are both in a compressed state.

[0025] Specifically, when the filter cartridge 4 needs to be cleaned or replaced after long-term use, the control handle 51 is turned, and the control handle 51 is used to drive the threaded rod 52 to rotate. The threaded rod 52 drives the middle connecting block 53 to move outward on the outer wall of the threaded rod 52 itself through the cooperation of the internal connecting column, so that the second receiving plate 3 gradually moves away from the first receiving plate 2, driving the first positioning rod 54 and the second positioning rod 55 to gradually separate from the first receiving plate 2, thereby removing the filter cartridge 4 from the inner wall of the valve body 1, facilitating cleaning and replacement, and solving the problem that the filter device of the one-way valve needs to be cleaned or replaced after long-term use, thereby ensuring subsequent filtering efficiency. However, the disassembly and assembly operation of the filter device is relatively cumbersome, consumes a lot of time and energy, and is not practical enough.

[0026] When installing the filter cartridge 4, it is only necessary to align the two sets of connecting groove bodies 6 of the first receiving plate 2 and the second receiving plate 3, and then rotate the control handle 51 in the opposite direction to drive the second receiving plate 3 close to the first receiving plate 2, so that the first positioning rod 54 and the second positioning rod 55 are inserted into the connecting groove body 6 of the first receiving plate 2. Since the reinforcement blocks A7 and B8 are in the cavity of the connecting groove body 6, the reinforcement blocks A7 and B8 are in a compressed state, so after being inserted into the connecting groove body 6, the connection is extremely stable.

[0027] Working principle: When disassembling, turn the control handle 51 and use the control handle 51 to drive the threaded rod 52 to rotate. The threaded rod 52 drives the middle connecting block 53 to move outward on the outer wall of the threaded rod 52 itself through the cooperation of the internal connecting column, so that the second receiving plate 3 gradually moves away from the first receiving plate 2, driving the first positioning rod 54 and the second positioning rod 55 to gradually separate from the first receiving plate 2, thereby moving the filter cartridge 4 out from the inner wall of the valve body 1. When installing, align the two groups of connecting groove bodies 6 of the first receiving plate 2 and the second receiving plate 3, and then rotate the control handle 51 in the opposite direction to drive the second receiving plate 3 close to the first receiving plate 2, so that the first positioning rod 54 and the second positioning rod 55 are inserted into the connecting groove body 6 of the first receiving plate 2.
