Description

Technical Field

[0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an anti-clogging valve for sewage treatment. Background Art

[0002] During sewage treatment, in order to regulate the water flow in the pipeline and ensure the normal operation of the sewage treatment system, the opening and closing of the regulating valve is often used to control the flow rate to ensure that the final sewage output meets the requirements of the treatment process.

[0003] At present, some stop valves are controlled by the up and down movement of the valve disc. When dealing with sewage containing grease and particulate matter, when the stop valve is closed, the particulate matter in the sewage is very likely to settle in the pipe directly below the valve disc. Even if the valve disc moves up to open, the accumulated particulate matter will still block the water flow, thereby causing the valve to become clogged, which is not convenient for practical use. At the same time, because most stop valves are kept open for a long time, sewage will enter the gap between the valve stem and the valve seat. Under the action of grease, it is very easy for sediment to adhere to the gap between the valve stem and the valve seat, and the valve stem and the valve seat will adhere to the sediment, forcing the valve stem to be unable to normally control the closing and opening of the valve disc, and it is very easy to cause the valve to not be fully closed, which is not convenient for practical use. In addition, due to the unique low inlet and high outlet of the stop valve, some small strips such as hair, paper, fibers, etc. will be attached to the sealing surface. The existing valve disc cannot be cleaned when closed, which can easily cause the valve to be loosely closed, which is not convenient for practical use. Summary of the Invention

A second rubber tube is sleeved on the movable rod, and one end of the inner wall of the second rubber tube is fixedly connected to the inner wall of the sealing groove, and the other end of the inner wall of the second rubber tube is fixedly connected to the inner wall of the valve disc.

[0008] Preferably, the sealing assembly includes a first rubber tube, a rotating shaft and a sealing layer, a movable hole is opened on the rotating shaft, and the rotating shaft is sleeved on the valve stem, a sealing thread is provided on the outer wall of the rotating shaft, a thread groove is fixedly opened on the inner wall of the top hole, the sealing thread is sealedly connected to the thread groove, a sealing layer is fixedly installed on the bottom of the rotating shaft, the sealing layer is located above the valve disc, and the side wall of the sealing layer is in sealing contact with the inner wall of the valve seat, the first rubber tube is sleeved on the valve stem, and the upper and lower ends of the first rubber tube are respectively fixedly connected to the bottom of the sealing layer and the top of the valve disc.

[0009] Preferably, sliding grooves are symmetrically provided on both sides of the inner wall of the movable hole, and plug blocks are symmetrically installed on both sides of the outer wall of the valve stem, and the plug blocks are embedded in the inner sides of the sliding grooves.

[0010] Preferably, a through hole is provided on the upper part of the valve stem, a rotating rod is provided inside the through hole, the rotating rod is L-shaped, and slots are provided at equal intervals on the side wall of the valve seat. The diameter of the rotating rod is smaller than the diameter of the slot, and rubber extrusion strips are symmetrically installed on both sides of the inner wall of the slot.

[0011] Preferably, a chimeric block is fixedly mounted on the inner wall of the slot near the upper and lower ends thereof, and a fixing hole is opened at one end of the rotating rod near the valve seat, and the chimeric block can pass through the rotating rod through the fixing hole.

[0012] Preferably, the water outlet is a T-shaped hole, and the diameter of the water outlet is greater than the length of the rotating plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) The present invention is provided with a valve stem, a lifting rod and a rotating plate. When opening the stop valve, the user can rotate the valve stem. Since the movable rod is inserted into the bottom of the valve stem through the sliding of the lifting rod, when the valve stem rotates, the side wall of the lifting rod squeezes the inner wall of the lifting hole, thereby synchronously driving the movable rod to rotate. Since the bottom of the movable rod is fixedly connected to the rotating plate, the operator can use the rotating rotating plate to loosen the long-term accumulation under the valve disc when opening the stop valve, thereby ensuring smooth water flow when the stop valve is opened. This solves the problem that particulate matter in sewage is easily deposited in the pipe directly below the valve disc. Even if the valve disc moves up to open, the accumulated particulate matter will still block the water flow, thereby causing the valve to be blocked.

[0015] (2) The present invention is provided with a valve stem, a valve seat and a sealing layer. When the user opens the stop valve, the rotation of the valve stem will synchronously drive the rotating shaft to rotate through the interlocking connection between the plug and the slide groove. Since the rotating shaft is threadedly connected to the valve seat, when the rotating stem starts to rotate, the rotating shaft immediately moves upward inside the valve seat, causing the sealing layer to contact the inner wall of the valve body. The sealing layer and the first rubber tube block the direct contact between the sewage and the valve stem, the rotating shaft and the valve cover, thereby preventing the valve stem from being unable to normally control the normal closing and opening of the valve disc due to oil adhesion.

DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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 Figure 1-Figure 4 As shown, the present invention provides the following technical solutions: an anti-clogging valve for sewage treatment includes a valve body 11, a Z-shaped sealing surface 27 is fixedly installed inside the valve body 11, a water outlet 26 is provided at the center of the surface of the sealing surface 27, a valve seat 5 is fixedly installed above the surface of the valve body 11, a top hole 23 is provided on the valve seat 5, a valve stem 15 is passed through the top hole 23, the valve stem 15 and the valve seat 5 are sealed and movably connected by a sealing component, the sealing component is used to control the up and down sliding of the valve stem 15, a valve disc 8 is fixedly connected to the bottom of the valve stem 15, the valve disc 8 is embedded in the water outlet 26, and the valve The bottom of the petal 8 is connected to the rotating plate 9 through a movable component. Through holes 10 are opened at equal intervals on the surface of the rotating plate 9. The movable component is used to control the distance between the rotating plate 9 and the sealing layer 6. The movable component includes a lifting rod 12, a movable rod 22 and a second rubber tube 17. A linkage groove 30 is opened in the bottom center of the valve stem 15. The movable rod 22 is inserted into the linkage groove 30. A lifting hole 18 is opened on the upper part of the side wall of the movable rod 22. The lifting rod 12 is passed through the lifting hole 18. The two ends of the lifting rod 12 are fixedly connected to the inner wall of the linkage groove 30, and the bottom of the movable rod 22 is fixedly connected to the top of the rotating plate 9.

[0023] Through the above technical solution, since the lifting rod 12 is arranged inside the lifting hole 18, when in use, the user can rotate the valve stem 15 and use the lifting rod 12 to squeeze the side wall of the lifting hole 18, thereby driving the movable rod 22 and the rotating plate 9 at the bottom of the movable rod 22 to rotate, and use the side wall of the rotating plate 9 to loosen the sediment deposited on the sealing surface 27 and under the water outlet 26 through multiple squeezing. When the stop valve is opened, the operator uses the rotating rotating plate 9 to loosen the long-term accumulation under the valve disc 8, thereby ensuring smooth water flow when the stop valve is opened, and solves the problem that particulate matter in sewage is easily deposited in the pipe directly below the valve disc 8. Even if the valve disc 8 moves up and opens, the accumulated particulate matter will still block the water flow, thereby causing the valve to be blocked.

[0024] In addition, during normal use, the sewage will first contact the rotating plate 9 before passing through the sealing surface 27, and the through holes 10 opened on the rotating plate 9 will be used to wrap around the flocs to prevent them from hanging on the sealing surface 27. Before closing the stop valve, the rotating plate 9 can also be driven to rotate by rotating the rotating rod 2, thereby wrapping up part of the lower end of the flocs and separating them from the sealing surface 27, lowering the valve flap 8 so that it cannot be completely closed, resulting in a problem of loose closure.

[0025] Furthermore, a sealing groove 16 is provided on the surface of the movable rod 22, and the sealing groove 16 is located below the adjusting hole 20. A second rubber tube 17 is sleeved on the movable rod 22, and one end of the inner wall of the second rubber tube 17 is fixedly connected to the inner wall of the sealing groove 16, and the other end of the inner wall of the second rubber tube 17 is fixedly connected to the inner wall of the valve disc 8.

[0026] Please refer to Figure 1 and Figure 3 Since the second rubber tube 17 has a certain degree of flexibility and the movable rod 22 is inserted into the linkage groove 30, when the user rotates the valve stem 15 to slowly drive the valve disc 8 to move up and open the water outlet 26, the rotating plate 9, under the action of its own gravity, causes the lifting rod 12 to move downward inside the lifting hole 18, ensuring that the water outlet 26 is opened while ensuring that the rotating plate 9 is always in contact with the sediment below the water outlet 26, thereby improving the loosening effect and pulling the second rubber tube 17 to deform. While ensuring the normal movement of the movable rod 22, the second rubber tube 17 blocks the contact between the sewage and the lifting rod 12, thereby preventing the particles in the sewage from filling the lifting hole 18 and causing the movable rod 22 to be unable to move normally.

[0027] Furthermore, the sealing assembly includes a first rubber tube 7, a rotating shaft 3 and a sealing layer 6. A movable hole 19 is opened on the rotating shaft 3, and the rotating shaft 3 is sleeved on the valve stem 15. A sealing thread 24 is provided on the outer wall of the rotating shaft 3, and a thread groove 25 is fixedly opened on the inner wall of the top hole 23. The sealing thread 24 is sealed with the thread groove 25. The bottom of the rotating shaft 3 is fixedly installed with a sealing layer 6. The sealing layer 6 is located above the valve disc 8, and the side wall of the sealing layer 6 is in sealing contact with the inner wall of the valve seat 5. The first rubber tube 7 is sleeved on the valve stem 15, and the upper and lower ends of the first rubber tube 7 are fixedly connected to the bottom of the sealing layer 6 and the top of the valve disc 8 respectively. Slide grooves 13 are symmetrically opened on both sides of the inner wall of the movable hole 19, and plug blocks 21 are symmetrically installed on both sides of the outer wall of the valve stem 15. The plug blocks 21 are embedded in the inside of the slide groove 13. The water outlet 26 is a T-shaped hole, and the diameter of the water outlet 26 is greater than the length of the rotating plate 9.

[0028] Please refer to Figure 1-Figure 4When the user rotates the valve stem 15, since the plug 21 is embedded in the inside of the slide groove 13, when the valve stem 15 starts to rotate, the rotating shaft 3 is also driven to rotate synchronously, and then the threaded connection of the sealing thread 24 and the thread groove 25 is used to push the rotating shaft 3 to start rotating and move upward, and pull the first rubber tube 7 to deform, forcing the distance between the side wall of the sealing layer 6 and the bottom of the valve seat 5 to gradually shorten, so that the side wall of the sealing layer 6 and the bottom of the valve seat 5 are in close contact with each other to form a seal. At this time, the valve disc 8 is still rotating inside the water outlet 26. After ensuring that the sealing layer 6 and the bottom of the valve seat 5 are sealed, the valve stem 15 can be lifted to drive the plug 21 to move upward inside the slide groove 13, pulling the valve disc 8 to open the water outlet 26 and open the stop valve. The sewage is blocked by the sealing layer 6 and the first rubber tube 7 from direct contact with the valve stem 15, the rotating shaft 3 and the valve seat 5, thereby preventing the valve stem 15 from being unable to normally control the normal closing and opening of the valve disc 8 due to oil adhesion.

[0029] In addition, since the diameter of the water outlet 26 is greater than the length of the rotating plate 9, during routine maintenance, the user can remove the valve seat 5 to release the fixed connection between the valve seat 5 and the valve body 11, and then directly lift the valve seat 5 to remove the valve stem 15, the rotating shaft 3, and the movable rod 22 directly from the inside of the valve body 11 for cleaning and maintenance, which is convenient for cleaning the flocs on the rotating plate 9 and achieving the purpose of convenient use.

[0030] Furthermore, a through hole 1 is provided on the upper part of the valve stem 15, and a rotating rod 2 is passed through the inside of the through hole 1. The rotating rod 2 is L-shaped, and slots 4 are provided at equal intervals on the side walls of the valve seat 5. The diameter of the rotating rod 2 is smaller than the diameter of the slot 4. Rubber extrusion strips 14 are symmetrically installed on both sides of the inner wall of the slot 4. A chimeric block 28 is fixedly installed on the inner wall of the slot 4 near its upper and lower ends. A fixing hole 29 is provided at one end of the rotating rod 2 near the valve seat 5, and the chimeric block 28 can pass through the rotating rod 2 through the fixing hole 29.

[0031] Please refer to Figure 1-Figure 2 Since the rotating rod 2 is inserted into the through-hole 1 on the valve stem 15, when the user rotates the valve stem 15, the length of the lever arm of the rotating rod 2 can be adjusted by pushing the rotating rod 2, thereby ensuring that when the stop valve is seriously blocked, the user can still quickly loosen the deposits through the rotating plate 9, thereby achieving the effect of convenient use. When normally closed or opened, one end of the rotating rod 2 can be embedded in the interior of the card slot 4, and the rotating rod 2 can be fixed by the interlocking connection of the interlocking block 28 and the fixing hole 29 to prevent the valve disc 8 from moving up due to excessive water pressure when closing.

[0032] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
