Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to an easy-to-clean valve which is convenient for removing impurities and filtering. Background Art

[0002] Valves are control components in fluid delivery systems with functions such as shutoff, regulation, diversion, backflow prevention, pressure stabilization, diversion or overflow pressure relief. Valves used in fluid control systems can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. The flow rate of the liquid can be adjusted by adjusting the valve. Therefore, the demand for valves that are easy to adjust the flow rate is growing.

[0003] Existing valves generally do not have a filtering mechanism inside, because long-term use will cause the filter to become clogged, making it inconvenient to clean, resulting in a decrease in water flow and affecting circulation. Therefore, an easy-to-clean valve that is easy to remove impurities and filter is needed to improve the above problem. Utility Model Content

[0004] The purpose of the utility model is to provide an easy-to-clean valve that is convenient for removing impurities and filtering, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A valve that is easy to clean and is convenient for removing impurities and filtering, comprising a valve body, a drain port and a water inlet being respectively provided on both sides of the valve body, a lower sewage outlet being provided at the lower part of the valve body between the drain port and the water inlet, a threaded sleeve being provided at the lower end of the lower sewage outlet, a motor being fixedly provided at the bottom of the threaded sleeve, a rotating plate being provided for transmission at the upper end of the motor, an annular limiting groove being provided on the upper surface of the rotating plate, and a filter cartridge being provided on the inner side of the groove.

[0007] As a preferred solution of the present invention, the filter cartridge includes a mesh cartridge, a funnel-shaped partition and a collecting cartridge. The funnel-shaped partition is arranged between the mesh cartridge and the collecting cartridge, and the mesh cartridge is arranged corresponding to the drain outlet.

[0008] As a preferred solution of the present invention, a scraper is fixedly provided at the upper end of the lower sewage outlet. The scraper is arranged in a triangular shape, and the sharp corners of the scraper are fitted and connected to the inner surface of the mesh cylinder.

[0009] As a preferred solution of the present invention, a valve stem is threadedly connected to the interior of the valve body, a runner is fixed to the upper end of the valve stem, and a valve plug is fixed to the lower end of the valve stem.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. In the utility model, the valve stem is rotated and raised by the rotary wheel, thereby driving the valve plug to rise and open the valve. The liquid flows into the filter cartridge from the water inlet and is filtered through the mesh cylinder. The heavier debris gradually descends inside the mesh cylinder under the action of water flow and its own weight, passes through the funnel-shaped partition and enters the bottom collection cylinder. Since the collection cylinder is blocked by the funnel-shaped partition at the upper end, it is difficult for the water flow to flush out the internal debris. The lighter debris will adhere to the surface of the mesh cylinder and accumulate over time. After a period of use, the motor can be started once to drive the rotating plate to rotate, thereby driving the filter cartridge to rotate. It can not only adjust the filtering surface, but also remove some debris adhering to the surface through the scraper. When cleaning, just unscrew the threaded sleeve for cleaning.

[0022] A valve that is easy to clean and filter, comprising a valve body 2, with a drain port 6 and a water inlet 11 provided on both sides of the valve body 2, a lower drain port 7 provided between the drain port 6 and the water inlet 11, a threaded sleeve 8 provided at the lower end of the lower drain port 7, a motor 9 fixed at the bottom of the threaded sleeve 8, a rotating plate 10 provided at the upper end of the motor 9, an annular limit groove provided on the upper surface of the rotating plate 10, and a filter cartridge 5 provided inside the groove, the valve stem 3 is driven to rotate and rise by the runner 1, thereby driving the valve plug 4 to rise and open the valve, and the liquid flows into the filter cartridge 5 from the water inlet 11 and passes through the mesh The cylinder 13 is used for filtering, and the heavier debris gradually descends inside the mesh cylinder 13 under the action of water flow and its own weight, passes through the funnel-shaped partition 14 and enters the bottom collection cylinder 15. Since the collection cylinder 15 is blocked by the funnel-shaped partition 14 at the upper end, it is difficult for the water flow to flush out the internal debris. The lighter debris will adhere to the surface of the mesh cylinder 13 and accumulate over time. After a period of use, the motor 9 can be started once to drive the rotating plate 10 to rotate, thereby driving the filter cylinder 5 to rotate, which can not only adjust the filtering surface, but also remove some debris adhering to the surface through the scraper 12. When cleaning, unscrew the threaded sleeve 8 to clean it.

[0023] As an example of the present invention, the filter cartridge 5 includes a mesh cartridge 13 , a funnel-shaped partition 14 and a collecting cartridge 15 . The funnel-shaped partition 14 is disposed between the mesh cartridge 13 and the collecting cartridge 15 , and the mesh cartridge 13 is disposed corresponding to the drain outlet 6 .

[0024] As an example of the present invention, a scraper 12 is fixedly provided at the upper end of the lower sewage outlet 7 . The scraper 12 is arranged in a triangular shape, and the sharp corners of the scraper 12 are fitted and connected to the inner surface of the mesh cylinder 13 .

[0025] As an example of the present invention, a valve stem 3 is threadedly connected to the interior of the valve body 2 , a runner 1 is fixed to the upper end of the valve stem 3 , and a valve plug 4 is fixed to the lower end of the valve stem 3 .

[0026] Working principle: When in use, the valve stem 3 is rotated and lifted by the runner 1, thereby lifting the valve plug 4 to open the valve. The liquid flows into the filter cartridge 5 from the water inlet 11 and is filtered through the mesh tube 13. The heavier debris gradually descends inside the mesh tube 13 under the action of water flow and its own weight, passes through the funnel-shaped partition 14 and enters the bottom collection tube 15. Since the collection tube 15 is blocked by the funnel-shaped partition 14 at the upper end, it is difficult for the water flow to flush out the internal debris. The lighter debris will adhere to the surface of the mesh tube 13 and accumulate over time. After a period of use, the motor 9 can be started once to drive the rotating plate 10 to rotate, thereby driving the filter cartridge 5 to rotate. It can not only adjust the filtering surface, but also remove some debris adhering to the surface through the scraper 12. When cleaning, unscrew the threaded sleeve 8 to clean it.
