Abstract
The invention discloses an automatic flap valve device of a water pump and a manufacturing method of the automatic flap valve device. The automatic flap valve device comprises a water pump outlet and a flap valve, a supporting plate is arranged on the lower portion of the water pump outlet, the flap valve is movably connected to the supporting plate through a fixing plate, and counterweight iron is arranged at the lower end of the flap valve. When the water pump is started, water flow bursts open the flap valve, the flap valve is pressed by water flowing out, and therefore no resistance is applied to the water pump outlet; when the water pump stops drawing water, the flap valve loses pressure, the counterweight iron descends, the flap valve is lifted and attached to the water pump outlet to block the water pump outlet, and the water is prevented from flowing back along a pipeline.
Description
Technical field
The application relates to water pump flap device, particularly relates to the automatic flap valve device of a kind of water pump and manufacture method thereof.
Background technique
In existing middle-size and small-size water pump, flap valve is very important structural fittings, and it mainly controls channel water when water pump is shut down and does not reflux.But the flap valve of routine upwards starts, the coupling shaft of flap valve and water pump pipe is suitable for reading at water pump pipe, and starting of it continues jack-up flap valve by pumping for water pump impulse force, to close flap valve during shutdown by gravity.The light then tens kilogram weights then hundreds of kilogram of conventional middle-size and small-size water pump flap, relying on pumping for water pump impulse force flap valve to be continued jack-up needs to consume much electricity.
For reducing energy consumption, improve pumping station operation efficiency, a kind of opening angle is disclosed large in prior art, unresisted energy-saving automatic turnover flap valve when drawing water, according to mechanics principle, originally the flap valve being arranged on water outlet top is changed into and is arranged on water outlet bottom, flap valve bottom is provided with the balance weight iron being greater than flap valve weight, utilizing gravity to be lifted by flap valve is fitted on water outlet, water outlet is arranged to angle of inclination simultaneously, when flap valve closes, balance weight iron also has certain torsion and is applied on water outlet, when opening water pump, current wash flap valve open, the hydraulic pressure flowed out is utilized to live flap valve, therefore resistance be there is no to water outlet, stop pumping, flap valve loses pressure, balance weight iron decline is lifted flap valve and is fitted on water outlet, thus start the effect of blocking current and declining along outlet pipe, the type flap valve has following technical characterstic: 1, without the need to any start-stop device, can automatic on-off.2, safety and stability, efficient energy-saving.Non-resistance when this flap valve runs, when to close, impact force is little, the whirlpool produced when eliminating water hammer and water outlet; Without the need to hand, electricity, gas, hydraulic control system, not manual operation, saves a large amount of manpower and materials, improves pumping station operation reliability and unit efficiency, reduces operation expense, reduces pumping plant energy consumption.In actual motion, detect test center's test through national Ministry of Water Resources, this flap valve is than suspension type flap valve saving power 22.5%.3, easy to maintenance, long service life.Flap valve and accessory thereof adopt stainless steel material, can not corrosion, and its cushion is changed convenient, and sealing is reliable, and product structure advantages of simple, working life can reach more than 30 years, and easy to maintenance.
