Description
Technical field
The application is related to water pump field of drawing water, more particularly to a kind of construction method of the 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 in water
When pump is shut down, prevent to flow back in the water taken out in upper/channel.But conventional flap valve starts upwards, flap valve and water
The connecting shaft of pump line is on water pump water outlet mouth of pipe top, and, when drawing water, pumping for water pump impulse force will continue to jack up flap valve for it, leans on during shutdown
Flap valve self gravitation closes, light then then hundreds of kilograms of tens kilogram weights of flap valve of the conventional middle-size and small-size water pump for irrigation and drainage, according to
Flap valve is continued to jack up by pumping for water pump impulse force, it is therefore desirable to consume much electricity.
To reduce energy resource consumption, pumping station operation efficiency is improved, it is proposed that one kind 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, will be arranged on delivery port top originally
Flap valve is changed to be arranged on delivery port bottom, and flap valve is arranged on counter-jib support left end, and balance weight body is arranged on counter-jib support right-hand member,
Flap valve is when opening, the flap valve positioned at support left end and the balance weight body weight balancing positioned at support right-hand member, therefore delivery port is hindered
Power is smaller, stops pumping, and flap valve stops current along going out because right-hand member torque is bigger and backwater suction lid is on delivery port, so as to play
The effect of water pipe backflow, the type flap valve have following technical characterstic：1st, can automatic open close without any headstock gear；2nd, pacify
It is complete stable, efficient energy-saving；3rd, non-resistance when this flap valve is run, impact is small when closing, eliminates caused by water hammer and water outlet
Whirlpool；4th, without hand, electricity, air-liquid control, should not manual operation, save a large amount of manpower and materials, improve pumping station operation reliability and
Unit efficiency, reduce operation expense；5th, pumping plant energy consumption is reduced, this flap valve is clapped than suspension type in actual motion after tested
Door saves electric energy 22.5%；6th, flap valve and its accessory use stainless steel material, will not corrosion, it is convenient that its rubber sheet gasket is changed, close
Envelope is reliable, product structure advantages of simple, and service life is and easy to maintenance up to more than 30 years.
The content of the invention

Delivery port 1 is rung, smaller to water resistance, water pump stops pumping, and is closed at out because the effect of backwater power makes flap valve 3 lift automatically
On the front end tube wall of the mouth of a river 1, the tube wall of delivery port 1 is brought into close contact with the groove 21 of ring-shaped rubber pad 2 being arranged on flap valve 3, is kept away
Exempt from water to flow back along pipeline.
The present embodiment also discloses a kind of construction method of the automatic flap valve of irrigation and drainage water pump, and its feature includes following technique and step
Suddenly：
1) the mounted water pump water outlet mouth of pipe is set to top and turned forward by the installation of irrigation and drainage water pump with the installation of conventional water pump
Oblique delivery port 1, its angle of inclination are 40-80 °, and preferable angle of inclination is 45 °, is set on the bottom tube wall of pump outlet 1
Bearing 6 is put, bearing 6 is provided with connecting hole；
2) connecting hole of bearing 6 is flexibly connected with the connecting hole of the support 8 on counter-jib 5 with axle 7；
3) flap valve 3 is arranged on by the front end of counter-jib 5 by the connecting hole of flap valve connector 4 with axle 7, flap valve 3 is provided with pad
Piece 2, pad 2 are provided with groove 21；
4) active connection 9 is connected to the rear end of counter-jib 5 by axle 7, and counterweight connector is provided with the bottom of active connection 9
10, it is connected with spherical weights body 11 in the lower end of counterweight connector 10；
5) after above-mentioned 4 step is set, flap valve 3 is fitted on delivery port 1, and when opening water pump, current are washed open outside delivery port 1
Flap valve 3, flap valve 3 lies in the bottom of delivery port 1, and the balance weight body 11 at the rear portion of counter-jib 5 is with anterior flap valve 3 in support 8, bearing
6 junctions are anterior-posterior balance state, and flap valve 3 does not influence delivery port, do not have resistance to water outlet, and water pump stops pumping, due to backwater
The effect of power makes automatic lift of flap valve 3 close on delivery port 1, the front end tube wall of delivery port 1 and the annular being arranged on flap valve 3
Rubber sheet gasket groove 21 is brought into close contact, and avoids water from being flowed back along pipeline.
Above-described embodiment counter-jib, torque arm length, flap valve, counterweight are respectively：Anterior support 8 is 60 centimeters, supports 8 rear portions
For 20 centimeters, the mass of flap valve 3 is 20 kilograms, and the 8 anterior mass of counter-jib 5 of support are 3 kilograms, and the support mass of 8 rear portion counter-jib 5 is
1 kilogram, the mass of balance weight body 11 is 64.5 kilograms, and pump outlet face and horizontal plane angle are 45 °, and left side torque is M1, right side
Torque is M2, and the influence of equipment frictional force, the buoyancy of water and current rotation nest is disregarded.
When drawing water, counter-jib 5 is in horizontality, two end moments are：
M1=20*9.8*0.6+3*9.8*0.3=126.42 ox rice
M2=64.5*9.8*0.2+1*9.8*0.1=127.40 ox rice
Because two end moments are more or less the same, so head influence of the flap valve on water pump water outlet is smaller.
When water pump is cut off the water, because right-hand member torque is bigger and the effect of backwater pulling force makes flap valve 3 from dynamic circuit connector in pump line water outlet
On mouth 1, the torque at 8 both ends of at this moment counter-jib support is：
M1=20*9.8*0.30+3*9.8*0.15=63.21 ox rice
M2=64.5*9.8*0.1+1*9.8*0.05=63.70 ox rice
Right-hand member torque is more than left end torque, so flap valve is in stable closed state after closing.
In order to adjust right-hand member torque size, counterweight ball-type cast iron can left and right fine setting on counter-jib.Because Model of pump is different,
Delivery port size is also different, can do corresponding adjustment to the size and weight of automatic flap valve according to above-described embodiment.
