Description
Technical field
This application involves water pump field of drawing water, more particularly to a kind of manufacture 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, 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, and when shutdown leans on
Flap valve self gravitation closes, light then then hundreds of kilograms of tens kilogram weights of the 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 consumption, pumping station operation efficiency is improved, it is proposed that one kind is arranged on pump outlet lower part, opening angle
Degree is big, unresisted energy-saving automatic turnover flap valve when drawing water, and according to mechanics principle, will be installed on water outlet top originally
Flap valve is changed to be installed on water outlet lower part, and flap valve is arranged on counter-jib support left end, and weight body is arranged on counter-jib support right end,
Flap valve is when opening, the flap valve positioned at support left end and the weight body weight balancing positioned at support right end, therefore water outlet is hindered
Power is smaller, stops pumping, and flap valve stops current along going out because right end torque is bigger and backwater suction lid is on water outlet, so as to play
The effect of water pipe reflux, the type flap valve have following technical characterstic：1st, can automatic open close without any headstock gear；2nd, pacify
It is complete to stablize, it is energy-efficient；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, reduces operation expense；5th, pumping plant energy consumption is reduced, in actual operation after tested, this flap valve is clapped than suspension type
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 replaced, close
Envelope is reliable, product structure advantages of simple, and service life is and easy to maintain up to more than 30 years.

Lower part, the weight body 11 at 5 rear portion of counter-jib are anterior-posterior balance state in 6 junction of bearing with anterior flap valve 3, the not shadow of flap valve 3
Water outlet 1 is rung, smaller to water resistance, water pump stops pumping, and is closed at out since the effect of backwater power makes flap valve 3 lift automatically
On 1 front end tube wall of the mouth of a river, the tube wall of water outlet 1 is fitted closely with 2 groove 21 of ring-shaped rubber gasket 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, 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 water outlet 1, its angle of inclination are 40-80 °, and preferable angle of inclination is 45 °, is set on 1 lower part tube wall of pump outlet
Bearing 6 is put, bearing 6 is equipped 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 axis 7；
3) flap valve 3 is arranged on by 5 front end of counter-jib by the connecting hole of flap valve connector 4 with axis 7, flap valve 3 is equipped with pad
Piece 2, gasket 2 are equipped with groove 21；
4) active connection 9 is connected to 5 rear end of counter-jib by axis 7, is equipped with 9 lower part of active connection with reconnection
Part 10, spherical weights body 11 is connected with 10 lower end of counterweight connector；
5) after above-mentioned 4 step is set, flap valve 3 is fitted on water outlet 1, and when opening water pump, current are washed open outside water outlet 1
Flap valve 3, flap valve 3 lies in 1 lower part of water outlet, and the weight body 11 at 5 rear portion of counter-jib is with anterior flap valve 3 in support 8, bearing
6 junctions are anterior-posterior balance state, and flap valve 3 does not influence water outlet, 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 water outlet 1, the front end tube wall of water outlet 1 and the annular being arranged on flap valve 3
Rubber sheet gasket groove 21 fits closely, and avoids water from flowing 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, 3 mass of flap valve is 20 kilograms, and 5 mass of anterior counter-jib of support 8 is 3 kilograms, and support 8 rear portion counter-jib, 5 mass is
1 kilogram, 11 mass of weight body is 64.5 kilograms, and pump outlet face angle with horizontal plane is 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 oxen rice
M2=64.5*9.8*0.2+1*9.8*0.1=127.40 oxen rice
Because two end moments are not much different, so head influence of the flap valve on water pump water outlet is smaller.
When water pump is cut off the water, since right end 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 oxen rice
M2=64.5*9.8*0.1+1*9.8*0.05=63.70 oxen rice
Right end torque is more than left end torque, so flap valve is in stable closed state after closing.
In order to adjust right end torque size, counterweight ball-type cast iron can left and right fine setting on counter-jib.Because Model of pump is different,
Water outlet size is also different, can do corresponding adjustment to the size and weight of automatic flap valve according to above-described embodiment.
