Description
Technical field
The application relates to water pump field of drawing water, and particularly relates to the construction method of a kind of automatic flap valve of irrigation and drainage water pump.
Background technology
In the water pump of existing middle-size and small-size water drainage or irrigation, flap valve is critically important structural fittings, and it is mainly at water
When pump is shut down, stop the water backflow that will take out in upper/channel.But the flap valve of routine upwards starts, flap valve and water
The connecting shaft of pump line is on water pump water outlet mouth of pipe top, and it is when drawing water, pumping for water pump impulse force jack-up to be continued flap valve, leans on during shutdown
Flap valve self gravitation closes, light then the most hundreds of kilogram of tens kilogram weights of the flap valve of the conventional middle-size and small-size water pump for irrigation and drainage, depends on
By pumping for water pump impulse force, flap valve is continued jack-up, it is therefore desirable to consume much electricity.
For reducing energy resource consumption, improve pumping station operation efficiency, it is proposed that one is arranged on pump outlet bottom, opening angle
Degree is big, unresisted energy-saving automatic turnover flap valve when drawing water, and according to mechanics principle, originally will be arranged on outlet top
Flap valve changes into being arranged on outlet bottom, and flap valve is arranged on counter-jib and supports left end, and balance weight body is arranged on counter-jib and supports right-hand member,
Flap valve, when opening, is positioned at and supports the flap valve of left end and be positioned at the balance weight body weight balancing supporting right-hand member, therefore hinder outlet
Power is less, stops pumping, and flap valve is because right-hand member moment is bigger and backwater suction lid is on outlet, thus plays stop current along going out
The effect of water pipe backflow, the type flap valve has techniques below feature: 1, without any headstock gear, can automatic open close；2, peace
Complete stable, efficient energy-saving；3, non-resistance when this flap valve runs, when closing, impact force is little, produces when eliminating water hammer and water outlet
Whirlpool；4, control without hands, electricity, air-liquid, not manual operation, save a large amount of manpower and materials, improve pumping station operation reliability and
Unit efficiency, reduces operation expense；5, reducing pumping plant energy consumption, this flap valve is clapped than suspension type in actual motion after tested
Door saves energy 22.5%；6, flap valve and accessory thereof use stainless steel material, will not corrosion, its rubber sheet gasket is changed convenient, close
Envelope is reliable, and product structure advantages of simple, service life is up to more than 30 years and easy to maintenance.

Sheet 2 sticks with glue or pressing plate is fixed in supporting flap valve spacer groove 31；
6) application of flap valve: when opening water pump, current wash the flap valve 3 outside outlet 1 open, and flap valve 3 lies in outlet 1
Bottom, the balance weight body 11 at counter-jib 5 rear portion is anterior-posterior balance state with anterior flap valve 3 in bearing 6 junction, flap valve 3 not shadow
Ringing outlet 1, less to water resistance, water pump stops pumping, and closes at out owing to the effect of backwater power makes flap valve 3 automatically lift
On the tube wall of front end, the mouth of a river 1, the tube wall of outlet 1 fits tightly with ring-shaped rubber pad 2 groove 21 being arranged on flap valve 3, keeps away
Exempt from water to reflux along pipeline.
The present embodiment also discloses the construction method of a kind of automatic flap valve of irrigation and drainage water pump, and its feature includes following technique and step
Rapid:
1) installation of irrigation and drainage water pump is with the installation of conventional water pump, the mounted water pump water outlet mouth of pipe is set to top and turns forward
Oblique outlet 1, its angle of inclination is 40-80 °, and preferred angle of inclination is 45 °, sets on the tube wall of pump outlet 1 bottom
Putting bearing 6, bearing 6 is provided with connecting hole；
2) connecting hole of the connecting hole of bearing 6 with the support 8 on counter-jib 5 is flexibly connected with axle 7；
3) by the connecting hole of flap valve connector 4, flap valve 3 being arranged on counter-jib 5 front end with axle 7, flap valve 3 is provided with pad
Sheet 2, pad 2 is provided with groove 21；
4) active connection 9 is connected to counter-jib 5 rear end by axle 7, is provided with counterweight connector in active connection 9 bottom
10, connect in counterweight connector 10 lower end and have spherical weights body 11；
5) after above-mentioned 4 steps set, flap valve 3 is fitted on outlet 1, and when opening water pump, current are washed open outside outlet 1
Flap valve 3, flap valve 3 lies in outlet 1 bottom, the balance weight body at counter-jib 5 rear portion 11 and anterior flap valve 3 supporting 8, bearing
6 junctions are anterior-posterior balance state, and flap valve 3 does not affect outlet, do not have resistance, water pump to stop pumping, due to backwater to water outlet
The effect of power makes flap valve 3 automatically lift to close on outlet 1, the front end tube wall of outlet 1 and the annular being arranged on flap valve 3
Rubber sheet gasket groove 21 fits tightly, it is to avoid water refluxes along pipeline.
Above-described embodiment counter-jib, torque arm length, flap valve, counterweight be respectively: supporting 8 front portions is 60 centimeters, supports 8 rear portions
Being 20 centimeters, flap valve 3 mass is 20 kilograms, and supporting 8 anterior counter-jib 5 mass is 3 kilograms, and supporting 8 rear portion counter-jib 5 mass is
1 kilogram, balance weight body 11 mass is 64.5 kilograms, and water pump water outlet actinal surface and horizontal plane angle are 45 °, and left side moment is M1, right side
Moment is M2, and the impact of equipment frictional force, buoyancy of water and current rotation nest is disregarded.
When drawing water, counter-jib 5 is in level, two end moments are:
M1=20*9.8*0.6+3*9.8*0.3=126.42 cattle rice
M2=64.5*9.8*0.2+1*9.8*0.1=127.40 cattle rice
Because two end moments are more or less the same, so the head of water pump water outlet is affected less by flap valve.
When water pump is cut off the water, owing to right-hand member moment is bigger and the effect of backwater pulling force makes flap valve 3 automatically be combined in pump line water outlet
On mouthful 1, at this moment counter-jib supports the moment at 8 two ends and is:
M1=20*9.8*0.30+3*9.8*0.15=63.21 cattle rice
M2=64.5*9.8*0.1+1*9.8*0.05=63.70 cattle rice
Right-hand member moment is more than left end moment, so flap valve is in stable closed state after closing.
In order to regulate right-hand member moment size, counterweight ball-type cast iron can left and right fine setting on counter-jib.Because Model of pump is different,
Outlet size is the most different, according to above-described embodiment, size and the weight of automatic flap valve can be done corresponding adjustment.
