Description
Technical field
It the utility model is related to a kind of drainage pipeline flap valve device, especially a kind of buoyancy tank flap valve dress with pooling feature
Put.
Background technology
Buoyancy tank flap valve is a kind of using differential water pressures and dead weight keying, installed in pump drain pipe water outlet, for preventing water
The one-way water stop valve of flow backwards when pump is shut down, it generally has stainless steel, cast iron or composite material etc. to be made.What is used now is floating
Case flap valve generally comprises gate seat, door leaf and sealing rubber strip.Described gate seat one end is installed on the row through the drainage pipeline of wall
Water end (W.E.) is connected with the drainage pipeline, and the other end of the gate seat is discharge outlet, and the door leaf, the gate seat are housed before discharge outlet
There is sealing rubber strip between the door leaf, gate seat, door leaf and sealing rubber strip interact and seal.When door leaf is closed,
Due to being influenced be subject to door leaf dead weight and differential water pressures, a larger effect acted on gate seat and sealing rubber strip can be produced
Power.Long-time service, since the shock of active force can make sealing rubber strip be badly damaged, so that flap valve loses leakproofness, occurs
The phenomenon of leak.In addition active force of the long duration of action on gate seat also easily makes door leaf, gate seat, hinge leaf and axis pin be damaged change
Shape, influences the service life of flap valve.
The content of the invention
The purpose of the utility model is to overcome the deficiencies in the prior art, there is provided a kind of door leaf closing time is controllable, water pump
The controllable buoyancy tank flap valve device with pooling feature of water pump reversing time after shutdown, and with simple in structure, easy for installation
The advantages of：
The utility model adopts the following technical solution：
A kind of buoyancy tank flap valve device with pooling feature, including gate seat and door leaf, gate seat and door leaf rotation connection, in door
Seat is equipped with sealing rubber strip, and the door leaf is babinet with interior cavity, and water is perfused with the cavity of the babinet.
Compared with prior art, the utility model has the following advantages that：
（1）The utility model uses water filling babinet, carries out counterweight to door leaf, makes it have pooling feature.It is especially logical
The screw thread inlet opening and threaded drain hole for being opened in door leaf top and bottom are crossed, can be poured water from upper screwed hole, from lower threaded hole
Discharge water, control the irrigation quantity of door leaf babinet, realize the counterweight on demand to door leaf, so as to control the proportion of door leaf, control door leaf
Proportion can control the closing time of door leaf, so control water pump shut down after due to outside drainage pipeline flow backwards cause water pump anti-
The time turned.
（2）One hydraulic bjuffer is housed, after water pump termination of pumping, flap valve water outlet pressure is more than on the buoyancy tank flap valve device
Water inlet pressure, flap valve accelerate, door leaf connects first when that will close in the case of door leaf dead weight and differential water pressures
The impact head on the hydraulic bjuffer head with noise reduction set is touched, hydraulic bjuffer has buoyancy tank flap valve door after the pressure that is collided
The kinetic energy brought during page closure is given to piston through impact head and piston rod, it is moved to no bar oil pocket.Originally buffer internal pressure
A return spring, piston and hydraulic oil are housed in cylinder.Fluid in the movement extruding working chamber of piston, makes return spring pressure
Contracting, while fluid is squeezed out from no bar oil pocket, there is bar oil pocket into annular oil cavity, then from annular oil cavity entrance.Work as door leaf
During in closure state, resistance is also stable at maximum.The process that buffer is compressed is done work by piston press fluid
Process.This process consumes a large amount of kinetic energy, plays cushioning effect.When door leaf is opened, piston is pushed into original by return position spring
Beginning position, complete a working cycles.Non-return valve wherein in hydraulic bjuffer, is a kind of check valve, when buoyancy tank flap valve door leaf
Closure hit hydraulic bjuffer impact head, make piston to no bar oil pocket move when, at this moment non-return valve does not work, piston slowly squeezes
Pressure oil liquid and make piston to no bar oil pocket slowly movement so that door leaf slowly closes.When buoyancy tank flap valve door leaf is opened, piston
Home position is pushed into by return spring, at this moment non-return valve works, and the fluid for making to have bar oil pocket rapidly flows towards no bar oil pocket, makes work
Plug is rapid to be resetted, the drag reduction for bearing spring, increases the service life of spring., can be with the action of hydraulic bjuffer
Weaken shock impulse force during buoyancy tank flap valve door leaf closure, further improve the service life of buoyancy tank flap valve.
（3）In the utility model, gate seat, door leaf and sealing rubber strip, which cooperate, can be used for the unlatching of control outlet pipe close
Close, wherein door leaf is the babinet of closing.
