Description

Technical Field

[0001] The utility model relates to the technical field of filter valves, in particular to an environmentally friendly self-cleaning double filter valve. Background Art

[0002] The filter valve is an indispensable device in the pipeline series for conveying media. It is usually installed at the inlet end of hydraulic control valves, pressure reducing valves, pressure relief valves, water level valves and other equipment to eliminate impurities in the medium and prevent granular impurities from entering the channel and causing wall plugs, so as to protect the accessories on the equipment pipeline from wear and blockage. When cleaning is required, just take out the detachable filter cartridge, process it and reinstall it. Therefore, it is extremely convenient to use and maintain.

[0003] During use of the existing filter valve, a filter cartridge is embedded inside the filter valve, which filters the internal water flow through the filter cartridge. However, since the impact force of the water source is relatively large when it flows, the filter cartridge will directly contact the impacting water source during filtering. The large impact of the water source will cause the filter cartridge to deform, resulting in incomplete filtration. Utility Model Content

When filtered impurities are accumulated inside the filter cartridge, the drain valve pipe is opened, so that the impurities filtered inside the filter cartridge can quickly enter the drain valve pipe through the arc-shaped base, so that impurities accumulation can be avoided, thereby achieving an environmental protection effect.

[0024] The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows:

[0025] Embodiment 1:

[0026] This embodiment provides a specific structure of an environmentally friendly self-cleaning double filter valve, such as Figure 1-4 As shown, it includes a filter valve body 1 and a filter assembly 3 embedded in the filter valve body 1, and the filter assembly 3 and the filter valve body 1 are detachably installed;

[0027] The filter assembly 3 includes a filter cartridge 31 connected to the filter valve body 1, and an arc filter plate 32 is embedded in the filter cartridge 31. When the filter cartridge 31 is impacted, the stability of the filter cartridge 31 is improved under the support of the arc filter plate 32. A limiting plate 34 is provided at one end of the filter cartridge 31, and a base 33 is provided at the inner wall of the filter cartridge 31 at one end of the limiting plate 34. When filtered impurities are accumulated in the filter cartridge 31, the drain valve pipe 9 is opened, so that the impurities filtered in the filter cartridge 31 can quickly enter the drain valve pipe 9 through the base 33 of the arc structure, thereby avoiding the accumulation of impurities and achieving an environmental protection effect. The base 33 is an arc structure, and a filter cartridge 31 is provided inside the filter assembly 3, and an arc filter plate 32 is provided inside the filter cartridge 31. The arc filter plate 32 is located on one side of the water outlet pipe 5. When water source enters from the water inlet pipe 4, the impact force on the filter cartridge 31 itself can be reduced through the arc filter plate 32, and deformation can also be avoided while the filter cartridge 31 filters the water source.

[0028] An end cover 2 is provided at the intersection of the filter valve body 1 and the filter assembly 3, which is used to limit the filter assembly 3 installed inside the filter valve body 1. The end cover 2 is located on the filter cartridge 31 and is provided with a drain valve pipe 9. A plurality of connecting holes 10 are provided around the end cover 2. If it is necessary to clean the filter cartridge 31, the valve inside the outlet pipe 5 is closed, and then the drain valve pipe 9 inside the end cover 2 is opened. Water flows in from the inside of the water inlet pipe 4, and impurities inside the filter cartridge 31 are discharged from the drain valve pipe 9.

[0029] By adopting the above technical solution:

[0030] A filter cartridge 31 is provided inside the filter assembly 3, and an arc-shaped filter plate 32 is provided inside the filter cartridge 31. The arc-shaped filter plate 32 is located on one side of the water outlet pipe 5. When water enters from the water inlet pipe 4, the arc-shaped filter plate 32 can reduce the impact force on the filter cartridge 31 itself, thereby avoiding deformation while the filter cartridge 31 filters the water.

[0031] Embodiment 2:

[0032] This embodiment provides a specific structure of an environmentally friendly self-cleaning double filter valve, such as Figure 1-4 As shown, a water inlet pipe 4 is provided at one end of the filter valve body 1, and a water outlet pipe 5 is provided at the other end of the filter valve body 1. A plurality of circular holes are provided inside the water inlet pipe 4 and the water outlet pipe 5. Water is introduced from the inside of the water inlet pipe 4, flows through the filter cartridge 31, and the water is filtered by the filter cartridge 31. The filtered water can be discharged from the water outlet pipe 5.

[0033] A first baffle 7 and a second baffle 8 are respectively provided on both sides of the filter cartridge 31 inside the filter valve body 1. When the filter cartridge 31 and the filter valve body 1 are installed with each other, one end of the filter cartridge 31 contacts with the first baffle 7 and the second baffle 8 respectively, and the first baffle 7 and the second baffle 8 play a role of limiting the filter cartridge 31.

[0034] The filter valve body 1 is provided with a limiting groove 6 at the intersection of the end cover 2. When the filter assembly 3 and the filter valve body 1 are connected to each other, the limiting plate 34 inside the filter assembly 3 contacts the limiting groove 6 inside the filter valve body 1, so that the filter assembly 3 and the filter valve body 1 can be tightly connected without loosening deviation.

[0035] The filter valve body 1 is located at one end of the water inlet pipe 4 and has a concave structure. When the water inlet pipe 4 enters the water source, the water source and the filter assembly 3 contact each other, and a part of the water source will impact the filter valve body 1. A concave structure is set at the impact position between the filter valve body 1 and the water source, so that when the water source impacts, the concave structure can better withstand the impact of the water source.

[0036] By adopting the above technical solution:

[0037] When the filter cartridge 31 and the filter valve body 1 are installed with each other, one end of the filter cartridge 31 contacts with the first baffle plate 7 and the second baffle plate 8 respectively, and the filter cartridge 31 is limited by the first baffle plate 7 and the second baffle plate 8. At the same time, when the filter assembly 3 and the filter valve body 1 are connected with each other, the limiting plate 34 inside the filter assembly 3 contacts with the limiting groove 6 inside the filter valve body 1, so that the filter assembly 3 and the filter valve body 1 can be tightly connected without loose deviation.

[0038] Working principle: when the water source enters the water inlet pipe 4, the water source and the filter assembly 3 contact each other, and a part of the water source will impact each other with the filter valve body 1. An inward-concave structure is set at the impact position between the filter valve body 1 and the water source, so that when the water source impacts, the inward-concave structure can better withstand the impact of the water source. The water source is introduced from the inside of the water inlet pipe 4 and flows through the filter cartridge 31. The inside of the filter cartridge 31 is provided with an arc-shaped filter plate 32, and the arc-shaped filter plate 32 is located on one side of the water outlet pipe 5. When the water source enters from the water inlet pipe 4, the arc-shaped filter plate 32 can reduce the impact force on the filter cartridge 31 itself, and deformation can be avoided while the filter cartridge 31 filters the water source. The water source is filtered by the filter cartridge 31, and the filtered water source can be discharged from the water outlet pipe 5.

[0039] If it is necessary to clean the filter cartridge 31 , close the valve inside the outlet pipe 5 , then open the drain valve pipe 9 inside the end cover 2 , allow water to flow in from the water inlet pipe 4 , and discharge the impurities inside the filter cartridge 31 from the drain valve pipe 9 .

[0040] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
