Embodiment

Such as Fig. 1, Fig. 2, Fig. 3, a kind of automatic pump comprises the pump housing 1, pressurized tank 2, outlet pipe 3; One end of the described pump housing is provided with water intake 4, and the other end of the pump housing is provided with one and swings flap valve 5, is provided with water outlet 6 on the top of the pump housing, is provided with an one-way valve 7 in described water inlet; Described pressurized tank is arranged on the upper end of the pump housing, and the described water outlet of the pump housing is communicated with described pressurized tank, is provided with tank body safety check 8 between the water outlet of the pump housing and pressurized tank; Described outlet pipe is vertically mounted on a side of pressurized tank, and the lower end of outlet pipe is communicated with the bottom of pressurized tank by 90 ° of elbows, is provided with out Water Check Valve 9 at the vertical pipeline section of outlet pipe; Outlet pipe extends upwardly to described automatic water lift of pump position.

Described swing flap valve is provided with the lower end and is installed in wobble plate 12 in the rotating shaft 11, described wobble plate is provided with the inclination angle towards pump housing inboard and with horizontal plane, wobble plate swings flap valve and opens when rotate pump housing inner chamber side below, wobble plate swings flap valve and closes when rotate the side top; Be provided with adjusting bolt 13 and balancing weight 14 at wobble plate.

Be provided with hand driving lever 16 at wobble plate, be provided with drag hook in the termination of described hand driving lever, hand driving lever is threaded connection and is fixed on the wobble plate.

One-way valve in described water inlet is an one-way valve that is provided with valve 17, and one-way valve is mounted on the water intake of the pump housing by flange.

The lower end of described tank body safety check is provided with conical gasket 18, end face at pump housing water outlet is provided with the taper hole corresponding with described conical gasket, be provided with balance weight iron 19 in the upper end of tank body safety check, the valve rod 20 of tank body safety check stretches in the pump housing by the through hole that is provided with at pump housing water outlet center, be set with a stage clip 21 at the valve rod that stretches into pump housing section, the two ends of described stage clip are crimped on pump housing internal surface and are installed between the set screw nut 22 of valve rod lower end.

Go out Water Check Valve and comprise valve seat 23, valve gap 24, valve core frame 25 and valve plate 26, described valve gap is installed in the upper end of valve seat by flange, described valve core frame is fixed in the inner chamber of valve seat by valve gap, valve core frame is the cross-bar-shaped that is provided with four legs, described valve plate is a circular copper plate, valve plate is installed in the valve core frame, and the external diameter of valve plate cooperates with the inner slide of described valve core frame leg, and valve plate can move up and down in valve core frame; Be provided with the sealing platform of protrusion in the bottom surface of valve base cavity, when valve plate is in the position, whereabouts, be pressed on the end face of described sealing platform and use Water Check Valve and close.

Automatic pump described in the utility model is installed in the place, water source of drop; Automatic pump swings the balancing weight on the wobble plate of flap valve when mounted according to height of water configuration, wobble plate can not opened under Action of Gravity Field when having current to flow out to swing flap valve, reaches when setting flow velocity wobble plate and closes flowing out the current that swing flap valve; Then adjust described adjusting bolt and stretch out the length of wobble plate, limit the maximum open amount of wobble plate.

In use, current are after the water intake of the pump housing enters pump housing inner chamber, and the hand driving lever on the wobble plate is stirred in operation by hand, makes the wobble plate opening and closing for several times, thereby automatic pump is entered from working state; Utilize the drag hook of hand driving lever termination can carry out easily the push-and-pull operation.

Such as Fig. 4, automatic pump enters under working state, when swinging the flap valve unlatching, current through one-way valve from water intake inflow pump intracoelomic cavity, flow out through swinging flap valve, when current reach the setting flow velocity, current promote the wobble plate of swing flap valve and close rapidly, such as Fig. 5, current moment of pump housing inner chamber stops to flow and producing water hammer effect, and the hydraulic pressure of pump housing inner chamber significantly raises rapidly, this moment the body water inlet closed check valve, current can not reflux, and the high water pressure pushing tank body safety check of pump housing inner chamber is opened, in the current feed pressure tank; The hydraulic pressure of pump housing inner chamber drops to normality subsequently, swings the wobble plate of flap valve under the effect of self gravitation, rotates to the pump housing is inboard, the swing flap valve is opened, current continue to flow out by swinging flap valve, and with this reciprocation cycle, current continue to be pressed into pressurized tank with certain frequency.

When the position of the water outlet of the water level Overpressure of a safety valve tank in the pressurized tank, the pressure in the pressurized tank raises, and current flow into outlet pipe; Under the pressure-acting of current, the valve plate that goes out Water Check Valve that is installed on the outlet pipe moves upward, and goes out Water Check Valve and opens, and current are risen to through outlet pipe sets lift; During the situation of the pressure drop in pressurized tank occurs, the water outlet closure of check ring prevents that current from flowing back in the pressurized tank.

Through experiment, be installed in the automatic pump at place, 1.5 meters height of water water sources, H-Max can reach 100 meters.
