Specific implementation
[0026] In order to make the person in the technical field better understand the technical scheme in the utility model, the technical scheme in the embodiment of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, rather than all the embodiments. Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without creative labor should belong to the protection scope of the utility model.
[0027] As shown in the utility model one embodiment of a kind of anti-blocking valve, including valve body 1 and valve core 2, valve core 2 is installed in the inside of valve body 1. Figures 1-2 As shown in the utility model one embodiment of a kind of anti-blocking valve, including valve body 1 and valve core 2, valve core 2 is installed in the inside of valve body 1.
[0028] Figures 1-2 As shown in the utility model one embodiment of a kind of anti-blocking valve, including valve body 1 and valve core 2, valve core 2 is installed in the inside of valve body 1.
[0029] As Figures 1-4 The lower end of the second valve body 6 is detachably mounted with a cover body 7, and the lower end of the second valve body 6 is provided with an opening, and the cover body 7 can seal the opening of the second valve body 6. When the impurities in the second valve body 6 are too much, the cover body 7 can be detached, so that part of the sewage flows out from the second valve body 6, and at the same time, the impurities in the second valve body 6 are also washed out, realizing the cleaning of the valve. It is worth noting that this way is generally suitable for the transportation of small pressure in the valve and pipeline, that is, the valve of the utility model is suitable for the transportation task of slow flow rate and small flow of sewage.
[0030] Specifically, as Figure 4 A plurality of first through holes 601 are formed in the second valve body 6, and a second through hole 701 matched with the first through hole 601 is formed in the cover body 7, and a bolt 8 matched with the second through hole 701 is mounted on the cover body 7, one end of the bolt 8 passes through the second through hole 701 and the first through hole 601, and the end passing through the first through hole 601 is threadedly connected with a nut 9, and the bolt 8 and the nut 9 are threadedly connected, and when the bolt 8 and the nut 9 are tightened, the second valve body 6 and the cover body 7 are fixed.
[0031] In order to avoid the situation that the filter screen 5 is blocked by impurities after long-term use, a cleaning mechanism 11 is mounted on the first valve body 4, which can clean the filter screen 5 and the inner wall of the second valve body 6, and is beneficial to remove the impurities blocked by the filter screen 5 in the valve body 1.
[0032] Specifically, as Figures 1-6 The third valve body 10 matched with the second valve body 6 is fixedly connected to the first valve body 4, the third valve body 10, the first valve body 4 and the second valve body 6 can form a channel, and the cleaning mechanism 11 is slidably connected in the channel. The cleaning mechanism 11 contacts the filter screen 5 and the inner wall of the second valve body 6 during sliding, so as to scrape off the impurities.
[0033] As Figures 1-6 The cleaning mechanism 11 comprises a rubber column 12 slidably connected in the channel, a first connecting rod 13 fixedly connected to the rubber column 12, and one end of the first connecting rod 13 penetrating through one end face of the third valve body 10 away from the second valve body 6. A plurality of first sealing rings 1001 matched with the first connecting rod 13 are fixedly connected to the third valve body 10, and the first sealing ring 1001 and the first connecting rod 13 are in interference fit, so as to avoid the leakage of sewage from the connection between the third valve body 10 and the first connecting rod 13 as much as possible.
[0034] Specifically, the first connecting rod 13 is further fixedly connected with a first handle 14. By pressing the first handle 14 downward, the rubber cylinder 12 can be moved to be close to one end of the filter screen 5 and the second valve body 6. In the process that the rubber cylinder 12 contacts with the inner wall of the filter screen 5 and the second valve body 6, the impurities on the inner wall of the filter screen 5 and the second valve body 6 can be scraped.
[0035] In addition, when the impurities in the second valve body 6 need to be discharged, the rubber cylinder 12 can be pushed to a position matched with the first valve body 4, so that the rubber cylinder 12 blocks the first valve body 4. In this process, the sewage cannot continue to flow, and the sewage is blocked by the rubber cylinder 12. Then, the cover body 7 is disassembled, the impurities in the second valve body 6 are cleaned, and then the cover body 7 is installed. In this way, the excessive sewage discharged from the second valve body 6 when the cover body 7 is opened can be reduced as much as possible.
[0036] In order to further improve the cleaning effect of the cleaning mechanism 11 on the inner wall of the second valve body 6 and the filter screen 5, as shown in Figures 5-6 , the rubber cylinder 12 is internally provided with a receiving groove 1201, the receiving groove 1201 is internally installed with a cleaning brush 16, the first connecting rod 13 is provided with a third through hole 1301, the cleaning brush 16 is fixedly connected with a second connecting rod 17 matched with the third through hole 1301, and a plurality of groups of second sealing rings 15 are further fixedly connected between the first connecting rod 13 and the second connecting rod 17. The second sealing rings 15 can reduce the situation that the sewage in the valve body 1 is discharged from the connection position of the first connecting rod 13 and the second connecting rod 17.
[0037] As shown in Figures 5-6 , the second connecting rod 17 is further fixedly connected with a second handle 18 at an end away from the cleaning brush 16. By pressing the second handle 18 toward one end of the second valve body 6, the cleaning brush 16 can be driven to move toward one end of the second valve body 6. The cleaning brush 16 is provided with a plurality of hard bristles. The hard bristles can clean the filter holes of the filter screen 5 and brush the inner wall of the second valve body 6. Compared with the rubber cylinder 12, the cleaning brush 16 has a better brushing effect. In the process that the cleaning brush 16 cleans the filter screen 5 and the inner wall of the second valve body 6, the anti-blocking valve can also operate normally.
[0038] In use, first, the direction of sewage discharge is confirmed, that is, the sewage passes through the first valve body 4 and then the main valve body 3. The filter screen 5 in the first valve body 4 can block impurities. When the anti-clogging valve is used for a period of time, impurities will accumulate on the filter screen 5 and in the second valve body 6. The impurities on the filter screen 5 and the second valve body 6 need to be cleaned. First, the second handle 18 is pressed. The second handle 18 drives the cleaning brush 16 to slide in the channel through the second connecting rod 17. The cleaning brush 16 contacts the inner wall of the filter screen 5 and the second valve body 6 and can be rotated to achieve better cleaning effect. After the filter screen 5 and the second valve body 6 are cleaned by the cleaning brush 16, the first handle 14 is pressed downward. The first handle 14 drives the rubber cylinder 12 to push the rubber cylinder 12 to the position of blocking the first handle 14 through the first connecting rod 13. Then, the second valve body 6 and the cover body 7 can be separated by disassembling the bolt 8 and the nut 9. The impurities remaining in the second valve body 6 can be discharged.
[0039] Preferably, an observation window matched with the channel can be further formed in the valve body 1. The first valve body 4, the filter screen 5 and the second valve body 6 can be observed through the observation window, so that the position of the rubber cylinder 12 and whether the impurities need to be cleaned can be determined.
[0040] It is apparent for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, but can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application.
