Abstract
Complicated, of high cost and the technical issues of cannot open flap valve for existing flap valve device, the utility model provides a kind of flap valve buffering mechanism, simple in structure, at low cost, can also assist to open flap valve and flap valve is not easy to be damaged when closed.Its technical solution is such：It includes fixed pulley, stent, the flap valve for being installed on outer wall, it is characterised in that：The stent is located at the flap valve top and passes through wall, the stent both ends are equipped with fixed pulley, the flap valve is connect with steel wire rope, and the steel wire rope is around on the fixed pulley of described stent one end through walls, is around on the fixed pulley of the other end across wall and is connect with the hoist engine on the inside of wall.
Description
Technical field
The utility model is related to a kind of check valve, specifically a kind of flap valve buffering mechanism.
Background technology
Flap valve is a kind of check valve with hinge for preventing from water pump being caused to reverse because of water body refluence when pumping plant is shut down, and is pacified
It realizes to close by dead weight at runner exit, during cut-off water by slap door and blocks flow.The flap valve that 70-80 age China is built is exhausted
Most of is formula of freely rising and falling, and this flap valve structure is reliable, it is simple, cheap to safeguard.Flap valve opening angle is big, and resistance is small, energy
Consume low, but impact force is big, jeopardizes flap valve self structure and the safety of building.It is being changed without flap valve, generally use liquid
Pressure or oil pressure carry out buffering percussive force, can also change door weight and structure, such as use binodal flap valve instead, but cost is high, difficult in maintenance
With the problems such as unreliable that stops.
A patent disclosed in early stage, publication number are found by retrieval：CN203960817U.This flap valve buffering mechanism flap valve
One end be also connected on steel wire rope, but the other end connection be electromagnetic generator.During work, pass through sensor sensing water
Position, sends signals to electromagnetic generator, and change the size of electric current on electromagnetic generator, so as to change size of current；Flap valve
During decline, electromagnetic generator is pulled, due to the repulsive force by one end magnet so as to reduce speed.Although it can be seen that flap valve
Speed is reduced, but it is complicated, and cost is higher, and this device can not achieve the unlatching of flap valve.
Utility model content
It is complicated, of high cost and the technical issues of flap valve cannot be opened for existing flap valve device, the utility model
A kind of flap valve buffering mechanism is provided, it is simple in structure, at low cost, can also assist to open flap valve and flap valve is not easy when closed
It is damaged.
Its technical solution is such：A kind of flap valve buffering mechanism including fixed pulley, stent, is installed on outer wall
Flap valve, it is characterised in that：The stent is located at the flap valve top and across wall, and the stent both ends, which are equipped with, determines cunning
Wheel, the flap valve are connect with steel wire rope, and the steel wire rope is around on the fixed pulley of described stent one end through walls, is around in across wall
It is connect on the fixed pulley of the other end with the hoist engine on the inside of wall.
Further characterized in that：
Angularly disposed another stent having for supporting the stent below the stent；
Wire netting is with outside the hoist engine.
After with such a structure, when flap valve, which is under pressure, to be begun to decline, hoist engine can be by steel wire rope to bat
Door provides a pulling force and then slows down the speed of decline, avoids that closing velocity is too fast to damage flap valve；Because device only by
Steel wire rope, stent, fixed pulley, hoist engine composition, thus it is simple in structure, it is of low cost；In addition, when needing to open flap valve,
Steel wire rope can be pulled to open flap valve by opening hoist engine, thereby using very convenient.
Description of the drawings
Fig. 1 is the structure chart of the utility model.
Specific embodiment
The utility model is described in detail below in conjunction with the accompanying drawings：
A kind of flap valve buffering mechanism as shown in Figure 1, including fixed pulley 3 and fixed pulley 4, stent, steel pipe and steel wire rope 2
The flap valve 1 of connection, the other end of steel wire rope 2 are equipped with hoist engine 6.Wire netting 5 is with outside hoist engine 6, can prevent sundries into
Entering hoist engine 6 influences work.Stent is angularly disposed on the metope on 1 top of flap valve, and another stent is located at tilted supporter top simultaneously
Wall is horizontally through, inclined support plays a supportive role to stent through walls, and stent through walls plays a supportive role to steel wire rope 2；It is through walls
Stent both ends are fixed with fixed pulley 3 and fixed pulley 4, and top is equipped with steel pipe through walls；Steel wire rope 2 is around on one end fixed pulley 3, is passed through
The steel pipe is around on the fixed pulley 4 of the other end, so as to be connected with the hoist engine 6 of the wall other end.
Operation principle is particularly solved below：
Switch off the pump 8 when, the motor 7 that first switches off the pump, at this time flap valve 1 opened under the action of its own gravity and hydraulic pressure
Begin to close downwards, open hoist engine 6 at this time, slowly discharge steel wire rope 2, wherein steel wire rope 2 passes through indoor fixed pulley 4, passes through
Steel pipe in wall is connected to by outdoor fixed pulley 3 on flap valve 1, and bumper and absorbing shock is carried out so as to which hoist engine 6 holds flap valve 1,
Until flap valve 1, which is closed, completes cutout requirement；In addition, when water pump 8 to be opened, the motor 7 of water pump is first opened, is similarly beaten at this time
It opens hoist engine 6 and shrinks steel wire rope 2, slowly pull-up flap valve 1, and flap valve 1 is fixed after fully opening.
Claims (3)
1. a kind of flap valve buffering mechanism, including fixed pulley, stent, the flap valve for being installed on outer wall, it is characterised in that：It is described
Stent is located at the flap valve top and across wall, and the stent both ends are equipped with fixed pulley, and the flap valve is connect with steel wire rope,
The steel wire rope is around on the fixed pulley of described stent one end through walls, across wall be around on the fixed pulley of the other end in wall
The hoist engine connection of side.
