Description
Technical field
The utility model relates to a kind of check valve with hinge of water conservancy and hydropower, specifically a kind of electromagnetic buffer flap valve.
Background technology
Flap valve prevents from while being pumping plant shutdown causing because water body flows backwards a kind of check valve with hinge that water pump reverses, and is arranged on runner exit place, realizes closing block current during cut-off water by slap door by deadweight.The flap valve of 70-80 age China construction is most is the formula of freely rising and falling, this flap valve reliable in structure, safeguard simple, cheap.Flap valve opening angle is large, and resistance is little, and energy consumption is low, but impact is large, jeopardizes the safety of flap valve self structure and building.Do not changing in flap valve situation, conventionally adopting hydraulic pressure or oil pressure to carry out buffering percussive force, also can change a weight and structure, as use binodal flap valve etc. instead, but cost is being high, the difficult in maintenance and cutout problem such as unreliable.Also can select better rubber buffer, but impact makes rubber deformation greatly, affects sealing.
Summary of the invention
In order to solve the above problems, the purpose of this utility model is to provide a kind of electromagnetic type buffer, thereby realizes the drawback that traditional flap valve buffering mechanism cost is high or service life is low.
To achieve the above object, the utility model has adopted following technical scheme: small and medium-sized pumping station flap valve electromagnetic buffer device, it mainly comprises: pump line, flap valve, wire rope, limit sensors, hinge seat, support, pulley, electromagnet generator, guide rail, level sensor, permanent magnet, current controller, signal amplifier, limit switch, described pump line is provided with support, on described support, is fixed with pulley; Wire rope one place is around on pulley, and flap valve end is fixed in wire rope one end, and the other end is fixed on electromagnet generator; Described electromagnet generator is located on guide rail, and guide rail end is fixed with permanent magnet;
Described flap valve is articulated with on hinge seat, and described hinge seat is provided with limit sensors;
One place of pump line is provided with level sensor, and described level sensor is controlled current controller after amplifying by signal amplifier signal;
Described electromagnet generator size of current is controlled by current controller;
On described limit sensors, limit switch is installed; Described limit switch is controlled the open and close circuit of electromagnet generator.
On above-mentioned pump line mouth, flap valve, be all covered with caulking gum skin.
The beneficial effects of the utility model: intelligent controlling: the outer water level of flap valve is higher, hydraulic pressure is just high, just larger to the active force of flap valve, impact when flap valve is closed is just larger, electromagnetic buffer device is to check water level height by induction type digital water level sensor, export corresponding electric current, when water level is higher, the electric current of output is just larger, and electric current is transformed into voltage through signal conditioning circuit, and voltage signal is controlled the electric current of electromagnet, electric current is large, magnetic field intensity is large, and between electromagnet, repulsive force is large, and buffering effect is better.The cushioning effect of common spring, hydraulic pressure, oleo cushion equipment can not change with SEA LEVEL VARIATION.Stickiness is good: electromagnetic buffer device is when flap valve is about to contact caulking gum, and limit switch disconnects, and tripping magnet power supply makes the flap valve laminating mouth of pipe, completes cutout; Little to caulking gum shock, stickiness is good.Common spring, oleo cushion equipment are when flap valve is completely closed, and reaction force is large, is unfavorable for that flap valve contacts with caulking gum.Consume energy low: after unlatching, electromagnet energising, electromagnetic repulsive force effect, pulls wire rope, and power-assisted flap valve aperture reduces discharge loss, consumes electric energy and reduces.
Accompanying drawing explanation

The specific embodiment
Below in conjunction with accompanying drawing 1-2, the specific embodiment of the present utility model is made a detailed explanation.
Embodiment: small and medium-sized pumping station flap valve electromagnetic buffer device, it mainly comprises: pump line 1, flap valve 2, wire rope 3, limit sensors 4, hinge seat 5, support 6, pulley 7, electromagnet generator 8, guide rail 9, level sensor 10, permanent magnet 11, current controller 12, signal amplifier 13, limit switch 14, described pump line 1 is provided with support 6, on described support 6, is fixed with pulley 7; Wire rope 3 one places are around on pulley 7, and flap valve 2 ends are fixed in wire rope 3 one end, and the other end is fixed on electromagnet generator 8; Described electromagnet generator 8 is located on guide rail 9, and guide rail 9 ends are fixed with permanent magnet 11;
Described flap valve 2 is articulated with on hinge seat 5, and described hinge seat 5 is provided with limit sensors 4;
One place of pump line 1 is provided with level sensor 10, and described level sensor 10 is controlled current controller 12 after amplifying by signal amplifier 13 signals;
Described electromagnet generator 8 size of current are controlled by current controller 12;
On described limit sensors 4, limit switch 14 is installed; Described limit switch 14 is controlled the open and close circuit of electromagnet generator 8.
On 1 mouthful described of pump line, flap valve 2, be all covered with caulking gum skin.
For operating principle, carrying out one below separates concretely:
When pumping plant is shut down, flap valve 2, under the gravity and hydraulic pressure of self, starts to rotate around hinge seat 5, the non-standard current signal of induction type level sensor 10 output, current signal, through signal amplifier 13, is controlled the size of current of electromagnet generator 8, thereby controls the magnetic field intensity of electromagnet; Flap valve 2 hauls motor magnet generator 8 by wire rope 3 and moves forward along track 9, because the permanent magnet 11 arranging is the electromagnet that homopolarity is relative with electromagnet generator 8, its repulsive force is to reduce and increase with distance, therefore electromagnet generator 8 speed fast-descendings, and then pulling flap valve 2 cushions, damping.When flap valve is about to contact caulking gum, limit switch 14 disconnects, and tripping magnet generator 8 power supplys make 1 mouthful of flap valve 2 laminating pump line, complete cutout requirement.
The utility model is claimed is the mechanical component of electromagnetic buffer device.Therefore limit sensors 4, electromagnet generator 8, level sensor 10, current controller 12, signal amplifier 13, its internal circuit is configured in this application and does not launch, and those skilled in the art, all knowing those accessories is all that communal technique (can be realized by mcu programming, and the approach realizing has multiple), what therefore unnecessary burden repeated is described.So the application of this patent does not exist technology point to disclose inadequate saying.
