Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of flap doors, in particular to an energy-saving free side-turning flap door. Background Art
[0002] The flap gate is mainly installed at the tail end of the drainage pipe to prevent external water from backflowing. It is composed of four parts: valve seat (valve body), valve plate, sealing ring and hinge. It is only used for round and square water outlets with one-way water flow. It has a strict structure and reliable operation. It does not require manual operation. The opening and closing force comes from the water source pressure. When the water pressure inside the flap gate is greater than the pressure outside the flap gate, it will open; otherwise it will close.
[0003] Water flows into the river through the drain pipe. The traditional flap gate plays a check function. When the water pressure in the pipeline is higher than that outside, the valve plate opens instead of opening it manually, thereby achieving energy saving. Since large impurities (floating objects) often float in the water flow, and the valve seat port of the flap gate does not have a filtering effect, a large amount of impurities will float in the discharged water and block the river. Utility Model Content
[0004] The utility model aims to provide an energy-saving free-side-flipping flap door, which has the purpose of filtering larger floating impurities, so as to solve the above-mentioned background technical problems.
[0005] The technical solution of the utility model for solving the above technical problems is as follows: an energy-saving free side-flipping flap door comprises a valve seat, a port on the inner surface of the valve seat is integrally fixedly connected with a cylinder, a valve plate is hinged on the surface of the cylinder by a hinge, the inner ring of the valve plate is located on the outer surface of the cylinder, the inner surface of the cylinder is provided with a filter cover, the outer surface of the filter cover and the inner surface of the cylinder are tightly fitted with the inner surface of the cylinder, the inner surface of the cylinder is annularly fixedly connected with a connecting plate, the connecting plate is fixedly connected with a guide cylinder on the side away from the inner surface of the cylinder, the inner surface of the guide cylinder is slidably connected with a sliding handle, the axis of the sliding handle is fixedly connected with a guide rod, the two end surfaces of the guide rod penetrate the guide cylinder and extend to the outer surface of the guide cylinder, the surface of the guide rod is sleeved with a spring, the spring is fixedly connected to one end of the sliding handle and the inner wall of the guide cylinder respectively, the end surface of the guide rod close to the filter cover is fixedly connected with a connecting seat, and the connecting seat and the filter cover are detachably connected.
[0006] Preferably, a threaded hole is opened at the axis of the connecting seat, and the inner surface of the threaded hole is threadedly connected with a mounting screw, the mounting screw passes through the filter cover and extends to the outside of the filter cover, and is tightly fitted by a sleeve gasket.
[0007] Preferably, a rubber ring is sleeved on the outer surface of the filter cover, and the outer surface of the rubber ring is tightly fitted with the inner surface of the cylinder.
[0008] Preferably, a sealing ring may be sleeved between the inner surface of the valve plate and the outer surface of the cylinder, and the sealing ring is tightly fitted to the inner surface of the valve plate.
[0009] Preferably, the distance that the filter cover extends into the inner surface of the cylinder is greater than the moving distance of the guide rod on the inner surface of the guide cylinder.
[0010] 1. The beneficial effects of the utility model are as follows: when water flows out from the valve seat and the cylinder, the valve plate will be lifted up due to the pressure of the water flow, and the valve plate will be opened through the hinge. At the same time, the water pressure will push out the filter cover, and the filter cover will drive the guide rod to move through the connecting seat. At the same time, the guide rod slides on the inner surface of the guide cylinder through the sliding handle, and the spring is stretched through the sliding handle, and the filter cover is buffered by the action force of the spring to avoid damage to the filter cover due to long-term water flow pressure. At the same time, the filter cover can filter larger floating objects in the water flow. When the floating objects accumulate to a certain amount, the filter cover can be opened by disassembly to deal with the floating objects accumulated in the valve seat and the cylinder, thereby avoiding a large amount of floating impurities from clogging the river.
[0011] 2. The utility model facilitates assembly and disassembly between the filter cover and the connecting seat by providing a threaded connection between the mounting screw and the threaded hole provided in the connecting seat.
[0012] 3. The utility model sets a rubber ring on the outer surface of the filter cover, and the outer surface of the rubber ring is closely fitted with the inner surface of the cylinder, which can reduce the gap between the cylinder and the filter cover and increase the filtration of floating objects during water flow.
[0013] 4. The utility model has a filter cover extending into the inner surface of the cylinder by a distance greater than the moving distance of the guide rod on the inner surface of the guide cylinder, thereby preventing the filter cover and the cylinder from falling off due to excessive sliding distance of the guide rod on the guide cylinder.
