5) pad make: the pad described in step 1 be rubber note make or add in rubber magnetic note make, described annular groove adopts softer bipeltate or latex to make, or in bipeltate or latex, also add magnetic make, pad is fixed in supporting flap valve spacer groove with gluing or pressing plate;
6) application of flap valve: when opening water pump, current wash the flap valve outside water outlet open, flap valve lies in water outlet bottom, balance post-brachial balance weight body supporting with anterior flap valve, bearing joint is anterior-posterior balance state, mercury in balance arm in mercury tube is parallel in mercury tube, flap valve does not affect water outlet, resistance is not had to water outlet, water pump stops pumping, effect due to backwater power makes flap valve automatically lift, balance arm disequilibrium, mercury in the mercury tube of balance arm inside drops on mercury tube Lower Half, namely mercury weight offset is to support the right, thus the reset of acceleration flap valve closes on water outlet, front end tube wall and the ring-shaped rubber pad groove be arranged on flap valve of water outlet fit tightly, water is avoided to reflux along pipeline.
10. the method for construction of the automatic flap valve of a kind of water pump with mercury tube according to claim 1 or 9, its feature comprises following technology and step:
1) installation of water pump is with the installation of conventional water pump, and the mounted water pump water outlet mouth of pipe is set to the water outlet that top turns forward, its angle of inclination is 40-85 °, and pump outlet bottom tube wall arranges bearing, and bearing is provided with attachment hole;
2) attachment hole of the attachment hole of bearing with the support on balance arm is flexibly connected with axle, in balance arm, is provided with mercury tube;
3) by the attachment hole of flap valve link, flap valve is arranged on balance arm front end with axle, flap valve is provided with pad, and pad is provided with groove;
4) active connection is connected to balance arm rear end by axle, is provided with counterweight link in active connection bottom, is provided with balance weight body in counterweight link lower end;
5) after above-mentioned 4 steps set, flap valve is fitted on water outlet, mercury in the inner mercury tube of balance arm drops on mercury tube Lower Half, namely mercury weight offset is to support the right, when opening water pump, current wash the flap valve outside water outlet open, flap valve lies in water outlet bottom, balance post-brachial balance weight body supporting with anterior flap valve, bearing joint is anterior-posterior balance state, mercury in balance arm in mercury tube is parallel in mercury tube, flap valve does not affect water outlet, resistance is not had to water outlet, water pump stops pumping, effect due to backwater power makes flap valve automatically lift, balance arm disequilibrium, mercury in the mercury tube of balance arm inside drops on mercury tube Lower Half, namely mercury weight offset is to support the right, thus the reset of acceleration flap valve closes on water outlet, front end tube wall and the ring-shaped rubber pad groove be arranged on flap valve of water outlet fit tightly, water is avoided to reflux along pipeline.
