Abstract
The utility model discloses a counterbalanced flap valve. The counterbalanced flap valve comprises a water outlet pipe, a flap valve pipe and a flap valve and is characterized in that the middle lower part of a balanced bar is movably arranged on a hinged bracket at the top of the right end of the flap valve pipe by a hinge shaft; the outer wall of the upper end of the flap valve is fixed at the lower end of the balanced bar; a balanced cast iron block is fixed at the upper end of the balanced bar; and an anti-corrosion layer consisting of an asphalt coiled material or epoxy coal tar is respectively arranged on the inner wall and the outer wall of a water outlet pipe. The counterbalanced flap valve is arranged at a water outlet of an urban sewer water channel and adopts the lever principle; and the hinge shaft connected with the bracket serves as a center, the lower end of the balanced bar serves as a flap valve counterweight, and the upper end of the balanced bar is weighted by the cast iron block. The weighted balanced cast iron can meet the requirement of the flap valve on the set opening, so that the flap valve can be opened or closed automatically and can be operated automatically. When flood occurs in an outer river, the flap valve is closed automatically. When the water level of the outer river is lower than that in the water channel, the flap valve can be burst through due to the water quantity of a sewer, the opening of the flap valve can be maintained, and the water in the sewer can be drained successfully.
Description
Technical field
The utility model relates to flood gate, especially relate to a kind of can solve the municipal sewage system delivery port flood season flood pour in down a chimney the balance weight type flap valve of problem.
Background technology
At present, what the flood gate of sewer delivery port adopted is common flap valve, because flap valve is to flexibly connect by door hinge and flap valve pipe, flap valve is near the water outlet hole of flap valve pipe, and the weight of flap valve is heavier, even bigger impact of water is arranged in the sewer, also can only reluctantly flap valve be washed open a narrow crack between a door and its frame, this moment, less rubbish can be gone out from narrow crack between a door and its frame, and bigger rubbish will get lodged in the crack between a door and its frame mouth and block flap valve, and make more follow-up rubbish get lodged in the crack between a door and its frame place, greatly influence draining; When flood took place in outer river, because bigger rubbish blocks flap valve and can't fasten, outer river can enter sewer from flap valve again to flap valve, causes flood to pour in down a chimney and goes down town again.In addition, because opening and closing device will be installed, just need influence bigger to civic landscape at surface construction framed bent and management house.
Summary of the invention
The purpose of this utility model just provides that the inside and outside water level situation flap valve of a kind of basis can be opened or close automatically, operation automation, flap valve aperture in the time of solving the sewer water outlet, prevent that when flood takes place flood from pouring in down a chimney the balance weight type flap valve of going down town, satisfy civic landscape.
The purpose of this utility model is achieved in that
A kind of balance weight type flap valve, comprise outlet pipe, flap valve pipe and flap valve, outlet pipe is identical with flap valve pipe diameter, outlet pipe is sleeved on the outer wall of sewer delivery port, the left end of outlet pipe is fixedly mounted on the flood control wall by screw, the left end of the right-hand member of outlet pipe and flap valve pipe is fixed together by flange, feature is: the top at flap valve pipe right-hand member is equipped with articulated stand, the middle and lower part of balancing pole is movably arranged on the articulated stand by hinge, the upper end outer wall of flap valve is fixed on the lower end of balancing pole, is fixed with the balance casting pig in the upper end of balancing pole.
Be provided with the anticorrosive coat that asphalt felt or coal-tar epoxy constitute at the inside and outside wall of the outlet pipe of making by cast iron pipe or steel pipe.
The utility model adopts lever principle, is the center with the hinge of articulated stand, and the lower end of balancing pole is that flap valve is heavy, and increase the weight of the upper end of balancing pole cylinder iron piece.What the balance casting pig that increases the weight of can reach flap valve drafts the aperture requirement, make flap valve balance casting pig heavy and that increase the weight of reach balance, realize the automatic unlatching of flap valve or close, reach the purpose of operation automation, thus the problem of flap valve aperture when having solved the sewer water outlet.The weight of balance casting pig can be determined by the debugging of installation process, and is simple in structure.The balance weight type flap valve can directly be built in the manhole of sewer delivery port, need not surface structures, can not influence civic landscape, can satisfy the requirement of civic landscape.
The utlity model has following advantage:
1, at the delivery port place of municipal sewage system the balance weight type flap valve is set, it can be according to inside and outside water level situation, utilize inside and outside water-head, flap valve can be opened or close automatically, make the operation automation of flap valve, the flap valve aperture that meets design requirement during the sewer draining, and keep the flap valve aperture and do not change with sewer delivery port flow effect.When the flood level in outer river was higher than water level 0.1m in the sewer, flap valve can be closed under the effect of water pressure outside automatically.When the water level in outer river was lower than water level 0.1m in the sewer, the water yield of sewer can be washed flap valve open, and keeps the flap valve aperture, and the water of sewer is effluxed smoothly, avoids flap valve to result in blockage near the hole, influences draining.
2, the flood gate of sewer delivery port adopts the balance weight type flap valve, and directly builds in the manhole of sewer delivery port, need not above ground structure, can not influence civic landscape, can satisfy the requirement of civic landscape.
