Preferably, the winch is arranged on a beam trolley, and the beam trolley can roll on the cross beam.

Preferably, the flap door installation angle is 5 °.

The utility model has the advantages of it is following:

1. the utility model discloses a two sliding flap valve simple structure, it is extensive to use, can be applicable to the play water flow way of different forms.

2. Two flap doors are pulled open towards two sides through a winch, the middle part of the flap doors is acted by a movable pulley, the required door opening force can be greatly reduced, the flap doors can be quickly closed by self weight when being closed, the buffer rubber in the middle of the two flap doors can play a role of leakage, the flap doors are pulled open towards the side direction, and the impact force on a water outlet flow channel can be ignored.

3. The utility model discloses a flap valve lay angle is 5, can utilize the dead weight to realize the sealed effect of manger plate under flap valve closed state.

Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.

As shown in fig. 1, the utility model relates to a double-pull flap valve, including circular water outlet flow channel 1, left flap valve 2, right flap valve 3, pivot 4, supporting member 5, buffering rubber 6, connecting axle 7, movable pulley 8, pulley spindle 81, roof beam car 9, hoist engine 91, hawser one 10, wheel 11, crossbeam 12, hawser two 13.

The water outlet section surface cutoff device of the circular water outlet runner 1 is composed of two semicircular flap doors, which are respectively: a left flap door 2 and a right flap door 3.

The left flap valve 2 and the right flap valve 3 are symmetrically distributed and are respectively connected with the supporting member 5 on the water outlet flow passage 1 through a rotating shaft 4, the left flap valve 2 can be opened in a left-side rotating mode around the rotating shaft 4, and the right flap valve 3 can be opened in a right-side rotating mode around the rotating shaft 4.

The outer sides of the two flap valves are respectively provided with a connecting shaft 7, and the connecting shafts 7 are fixedly connected with a movable pulley 8 through a first cable 10. One end of a cable II 13 passing through the movable pulley 8 is connected to the winch 91, and the other end is fixed on the side wall of the water outlet pool. The winch 91 on the beam car 9 achieves the purpose of opening the flap valve by pulling the movable pulley 8.

The inner sides of the two flap door leaves are provided with buffer rubbers 6 which can play a role of reducing impact force when the flap door is closed.

The placing angle of the two flap doors is 5 degrees, so that the flap doors can achieve the water retaining and sealing effects by utilizing the dead weight.

The beam car 9 comprises a winch 91 and wheels 11, is arranged on a beam 12, and can be adjusted in position on the beam 12 through rolling of the wheels 11.

The utility model relates to an application method of sideslip formula doublestage flap valve as follows:

when the flap valve needs to work, the winch 91 is used for pulling the second cable 13 to lift the movable pulley 8, and the movable pulley 8 is lifted to drive the left flap valve 2 and the right flap valve 3 to open towards two sides; when water outlet is finished, the winch 91 in the beam car 9 releases force, the flap doors can slide off and close freely from two sides by utilizing the dead weights of the left flap door and the right flap door, and the buffering rubber arranged in the two flap doors can play a role in buffering and stopping water.

The foregoing has outlined rather broadly the present invention in terms of general words and detailed description, but not of limitation, and modifications thereof that may be made without departing from the spirit of the invention are intended to be covered by the appended claims.
