Description

Flushing flap valve

Technical Field

The utility model belongs to the technical field of gates, and particularly relates to a flushing flap valve.

Background

The cleaning flap valve is mainly used for controlling water flow, storing water and flushing channels in urban underdrains. Is arranged at the middle upstream or the discharge port of the drop channel. Because the garbage in the sewage of the underdrain can be deposited and blocked at the downstream of the channel after a period of time, the channel is prevented from being blocked by the garbage, but the garbage in the underdrain is difficult to clean. The channel is not internally provided with light rays, is full of toxic gas and cannot be manually cleaned. Therefore, the flap valve needs to be cleaned and opened quickly, and a large amount of water flows in the channel quickly to achieve the purpose of washing the channel.

The washing flap valve is normally in a closed state, and water in the channel can be blocked before the flap valve when the flap valve is closed. When the flap valve is quickly opened when a certain water level is reached, water accumulated in the channel quickly flows in the channel to clean garbage and sundries deposited in the channel. Flushing the garbage out of the underdrain.

The existing flushing gate is applied, and the drop height of a channel has flap valves with various specifications and models according to the size of the channel. The single existing flap valve has certain problems:

(1) because the flap valve needs the retaining of longer time, the flap valve needs to be closed during the retaining, and when the retaining water level was great, the easy fatigue of flap valve locking mechanical system was become flexible, leads to the flap valve to leak, can't play the retaining effect.

(2) The flap valve is not opened slowly to drain water slowly when the opening speed of the flap valve is high. Otherwise the flushing effect is not achieved as well. The existing flap valve has the conditions that unlocking is not fast enough and water is discharged not fast enough.

(3) After the water is drained and the flushing is finished, the flap valve cannot be accurately reset, and the secondary locking is difficult.

SUMMERY OF THE UTILITY MODEL

The technical problems solved by the utility model are as follows: the flushing flap valve is stable in locking, good in sealing effect and capable of being opened and closed quickly.

The technical scheme is as follows: in order to solve the technical problems, the technical scheme adopted by the utility model is as follows:

a washing flap valve comprises a base and a flap valve, wherein the upper end of the flap valve is hinged on the base, and the lower end of the flap valve is provided with a locking mechanism; the locking mechanism comprises a locking connecting rod, a rotating lever, a locking shaft and a driver, the locking shaft is arranged on the flap valve, the driver is arranged on the base, one end of the rotating lever is hinged to the locking connecting rod, the other end of the rotating lever is hinged to the driver, meanwhile, the rotating lever is rotatably arranged on the base, a locking clamp is fixed on the locking connecting rod, the driver acts to drive the rotating lever to rotate and drive the locking connecting rod to horizontally move, the locking clamp movably hooks the locking shaft on the flap valve, and the flap valve is fixed to the base.

Preferably, a connecting rod fixing seat is arranged on the base, a limiting rod is arranged on the connecting rod fixing seat, a stroke groove is formed in the locking connecting rod, and the limiting rod penetrates through the stroke groove and is fixed on the connecting rod fixing seat.

Preferably, the connecting rod fixing seat, the limiting rod and the stroke groove are all provided with a plurality of corresponding positions.

Preferably, the flap door is provided with a plurality of ear plates, and the flap door is hinged to the ear plates through the eyebolt and the pin shaft, so that the flap door can rotate around the pin shaft to be opened or closed.

Preferably, a water outlet is formed in the base, a sealing surface connected with the water outlet is arranged on the periphery of the water outlet, and the sealing surface and the base are inclined.

Preferably, a sealing ring is arranged on the flap valve, and when the flap valve is in a closed state, the sealing ring is tightly attached to the sealing surface.

Preferably, the base is formed by welding steel plates, and the flap valve is formed by welding section steel and steel plates.

Preferably, the locking clip is in the shape of an open hook with a bevel, the opening facing the driver; the driver acts to drive the rotating lever to rotate, the locking connecting rod is driven to move horizontally, the locking clamp moves to hook the locking shaft on the flap valve, and the flap valve is fixed with the base.

Has the advantages that: compared with the prior art, the utility model has the following advantages:

(1) the washing flap valve changes the closing and locking direction of the flap valve in the past, and the former locking direction is the same as the opening direction of the flap valve. The reaction force of the flap valve water storage is caused to be in the same direction as the locking direction, and the reaction force is directly acted on the locking driver. The flap valve is locked for a long time and is easy to loosen slowly, so that the flap valve is not sealed tightly, and water leakage occurs. The locking direction of the locking card of the prior flap valve is changed through a connecting rod mechanism, and the locking direction is vertical to the opening direction of the flap valve. Therefore, the counterforce of the stored water can not directly act on the locking driving device, and the driver can be kept for a long time, so that the flap valve can be locked stably.

(2) In the past, most drivers and locking devices are in direct connection structures, and the locking stroke directly influences the opening speed of the flap valve. After the locking direction of the flap valve is changed, the flap valve is connected with the driver through the locking connecting rod. A rotating lever is arranged between the locking connecting rod and the driver, and the locking stroke can be changed through the lever proportion. The actuator can thus actuate the opening and closing of the locking device with a small stroke. The opening action of the flap valve is completed quickly.

(3) After the water is discharged and the flushing is finished, the flap valve returns to the closed position due to gravity. In order to enable the flap valve to return to the closed position more accurately, the flap valve discharge opening sealing surface and the wall surface have a certain angle of travel, so that the flap valve can completely lean against the sealing surface due to gravity to return to the closed state and is ready for locking again.
