Abstract

The utility model relates to a hand-operated water pump belonging to the technical field of water pumps, which is mainly composed of a piston, a cylinder, two self control pressure water valves and a hand-operated lever. Water enters the cylinder from the self control pressure water valve in a water absorption position under the action of the piston, and then, the water is transported from the self control pressure water valve in a water transporting position; ensured by two self control pressure water valves, the water can flow towards one direction and can not flow back; so the water absorbed from low position and transported for water demand position can be ensured.

Description

Hand-operated water pump

The utility model relates to a kind of non-mechanomotive force water pump, belongs to the pump technology field.

Used Lever type hand water pump has only one can control the water valve that water refluxes (below be referred to as the automatic control pressure water valve) automatically in the cylinder barrel bottom surface, raises and hoist () function or at a distance when water not being sucked up again.

The purpose of this utility model provides a kind of improved pumping plant.When sucking up water effectively, it raises hoist (or at a distance) again.

The purpose of this utility model is achieved in that in existing bottom surface or the side with Lever type hand water pump cylinder barrel installs an automatic control pressure water valve again.Promptly a hand water pump is installed two automatic control pressure water valves.When drinking up by first automatic control pressure water valve under the effect of water at piston, go by second automatic control pressure water valve output again and can not reflux.Piston can to-and-fro motion make the gas leakage of can not leaking between piston and the casing wall again in cylinder barrel.

The utility model is because only refill an automatic control pressure water valve on former hand water pump, thus simple in structure, reached water simultaneously and when sucking up, transferred to eminence (or at a distance) again and can not reflux.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the sectional drawing according to a kind of hand water pump that the utility model proposes.

Describe details and working condition in detail below in conjunction with Fig. 1 according to a kind of hand water pump that the utility model proposes.

Among Fig. 1,1,3 and 15 3 coupling shaft, 2 hand levers, 4 supporting rods, 5 cylinder barrels, 6 cross bars, ball chambers 7,11,8,12 balls, 9,10,13 pipe joints, 14 pistons, 16 connecting rods.

By cross bar 6, ball chamber 7, ball 8 and pipe joint 9 are formed the automatic control pressure water valve of suction place, by ball chamber 11, ball 12, pipe joint 10 and 13 is formed the automatic control pressure water valve of water delivery place.

Hand lever 2 is connected with piston 14 by connecting rod 16 by supporting rod 4 supportings, and supporting rod 4 is fixed on the thick stick tube 5, and piston 14 can to-and-fro motion in cylinder barrel 5 under the effect of hand lever 2.The cylinder barrel bottom surface is ball chamber 7 fixedly, the bottom fixed tube joint 9 of ball chamber 7, and the middle and upper part fixed transverse rod 6 of ball chamber 7 has ball 8 in the chamber.At the side or the bottom surface fixed tube joint 10 of cylinder barrel 5, the top of pipe joint 10 is ball chamber 11 fixedly, and there is ball 12 11 inside, ball chamber, and the top of ball chamber 11 is pipe joints 13.

When static, hand lever 2, piston 14 is in free state, ball 8 sealed pipe joints 9, ball 12 sealed pipe joints 10.

During work, the handle end of hand lever 2 lifts, the other end moves downward piston 14 by connecting rod 16, water in the cylinder barrel 5 is by 10 balling-ups 12 of pipe joint, go from pipe joint 13 outputs, ball 8 is sealed tube joint 9 at this moment, after hand lever 2 handle ends lift, when stopping, ball 12 is sealed tube joint 10 simultaneously.When the handle end of hand lever 2 was depressed, the other end moved upward piston 14 by connecting rod 16.Beneath water will come up by pipe joint 9 jack-up balls 8.Ball 8 can not be run out of ball chamber 7 owing to stopping of cross bar 6.Like this, motion and so forth, water will be drunk up continuously, and output comes.

Ball 8 and ball 12 also can be other shapes with said function.

Claims

1, a kind of by hand lever by the cylinder type hand water pump that connecting rod links to each other with piston, it is characterized in that cylinder bucket bottom surface installs two automatic control pressure water valves.
