Description
Technical Field
The utility model belongs to the flap valve field especially relates to a self-closing flap valve.
Background
The flap valve is widely applied to irrigation and drainage stations, hydropower stations, riverways, aquaculture, reservoirs, sewage treatment, municipal environmental protection and other hydraulic engineering. The flap valve consists of a door seat and a door cover which are connected through a hinge. The flap valve is a one-way valve arranged at the outlet of the drain pipe, and is opened when the water pressure in the flap valve is greater than the outside pressure, and is closed otherwise.
However, the existing flap valve has the main problems that the flap valve cannot be closed automatically or cannot be closed completely, so that a door cover and a door seat cannot be closed reliably, the sealing effect is poor, and water leakage is serious; sometimes, the door cover enters a movable dead zone due to an overlarge opening angle and cannot be closed, so that a large accident of the water delivery system is caused.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: the utility model aims at providing a can realize closing and close thorough flap valve from the time.
The technical scheme is as follows: the utility model discloses a self-closing flap valve, which comprises a door seat and a door cover hinged with the door seat; the door seat is provided with a door seat hinge support in an extending mode, the door seat hinge support is provided with a spiral sliding ladder-shaped support seat, the door cover is provided with a door cover hinge support corresponding to the door seat hinge support in an extending mode, the door cover hinge support is provided with a spiral sliding ladder-shaped support lug matched with the spiral sliding ladder-shaped support seat, and the door cover hinge support and the spiral sliding ladder-shaped support lug are fixedly connected through a hinge column.
Preferably, the flap valve may have a double-door type door cover.
Furthermore, the door seat hinge support and the door cover hinge support are provided with limit blocks. And a sealing part is arranged on the door seat corresponding to the sealing part of the door cover. The door seat is also provided with a magnet.
Furthermore, the spiral slide ladder-shaped supporting seat, the door seat hinge support and the door seat can be integrally arranged. The spiral sliding ladder-shaped supporting lug, the door cover hinged support and the door cover can be integrally arranged.
Has the advantages that: compared with the prior art, the utility model has the advantages that: the flap valve is provided with the corresponding spiral sliding ladder-shaped supporting seat and the spiral sliding ladder-shaped supporting lug through the door seat hinge support and the door cover hinge support, so that the door cover is automatically closed through energy conversion, the spiral sliding ladder-shaped supporting seat and the supporting lug are arranged, the condition that the opening angle of the door cover is free of dead zones is ensured, and meanwhile, the flap valve is tighter under the action of magnetic force when the door cover is close to the door seat through the magnet arranged on the door seat.

Detailed Description
The technical solution of the present invention will be further described in detail with reference to the accompanying drawings.
As shown in fig. 1 and 2, the self-closing flap valve of the present invention includes a door seat 1 and a double-open door cover 2, i.e. a left door cover and a right door cover, hinged to the door seat. Wherein, the symmetry extends on the door seat 1 and is equipped with door seat hinge bracket 3, and what correspond, the extension is equipped with on the door closure 2 with door seat hinge bracket 3 matched with door closure hinge bracket 5. The door seat hinge support 3 is provided with a support seat 4, the support seat 4 is in a spiral slide shape, similarly, the door cover hinge support 5 is provided with a support lug 6 corresponding to the support seat 4, and the support lug 6 is in a spiral slide shape matched with the support seat 4, as shown in fig. 3 and 4. The supporting seat 4 and the supporting lug 6 are fixedly connected through a hinge column 7 (namely a pin shaft).
Furthermore, the utility model discloses be equipped with stopper 8 on the door seat articulated mounting 3 and the door closure articulated mounting 5 of flap valve. The sealing part corresponding to the door cover 2 on the door seat 1 is provided with a sealing element 9 which can be a sealing ring, the door seat 1 is further provided with a magnet 10, the sealing element 9 ensures that the door cover 1 and the door seat 2 are watertight, and the magnet 10 is closed more tightly under the action of magnetic force when the door cover 2 is close to the door seat 1, so that the sealing effect is improved. The spiral sliding ladder-shaped supporting seat 4, the door seat hinge support 3 and the door seat 1 are arranged integrally or in a split mode. The spiral sliding ladder-shaped supporting lug 6, the door cover hinged support 5 and the door cover 2 can be arranged integrally or in a split way.
The working principle is as follows: when the water pump works, under the pushing of water flow pumped by the water pump (or pressure water flow in a pipeline), the door cover 2 rotates around the hinge column 7 and rises along the spiral steps at the same time, the door cover 2 is opened, and the water flow flows along the required direction; when the water pump is closed, the water pump stops working, the door cover 2 rotates around the hinge post 7 along the spiral steps under the action of gravity to be closed, and water flow is cut off.
