Abstract

The utility model relates to a hand convenient pump, comprising a suction tube, an outlet stop valve and a convenient pump nozzle. The hand convenient pump is characterized in that the convenient pump nozzle fixedly connected with the other end of the suction pipe is circular inside and hollow; a spherical body floating up and down is arranged in the hollow part; a gap is arranged between the spherical body and an inner circle wall of the convenient pump nozzle; the specific gravity of the spherical body is larger than the specific gravity of liquid; the upper part of the convenient pump nozzle is provided with a hollow limit crosspiece, and the lower part is hollow; the diameter of the hollow lower part is smaller than the diameter of the spherical body. The utility model has the advantages of wide application range, simple structure, portability, economy, utility, high safety, sanitation, and direct suction without a power supply.

Description

Manually make things convenient for pump

The utility model relates to a kind of manual liquid pump.

At present, people are extracting various liquid, during tap water, mostly adopting motor to connect the drive pump housing aspirates, this is for for a long time, comparatively convenient when measuring big extraction, but in the open air, non-transformer area or some small-sized workshops, family, the laboratory, in the wine-making industry, when people only need do the extraction of some small amount of liquid, the very inconvenience that but seems, and some people is in order to scheme conveniently, for example: when the extraction of the gasoline in petrol drum part is used for the use of vehicle, then adopt an end of a suction pipe to insert petrol drum, the other end aspirates with mouth, under the pressure reduction siphonage, after the gasoline suction, insert in fuel tank or the container, when aspirating like this, often in the gasoline suction nozzle, extremely unhygienic, and infringement people's health.

The purpose of this utility model is to provide a kind of power supply that need not, and simple in structure, safe in utilization, easy to carry, and what have widely-used scope manually makes things convenient for pump.

The technical solution of the utility model is finished like this: the pump suction nozzle that makes things convenient for of fixedlying connected with the suction pipe the other end is interior round hollow shape, have in the hollow one can upper and lower suspension spheroid, spheroid with make things convenient for pump suction nozzle inner round wall that certain interval is arranged, and the proportion of spheroid overweights the proportion of liquid, make things convenient for pump suction nozzle top to be provided with the spacing crosspiece of a hollow out, the bottom is hollow out also, and the diameter of hollow out is less than sphere diameter.

The utlity model has following advantage: the utility model can be widely used in mountain area, field, island, building site, rural area, small-sized machine maintenance engineering, wine-making industry, agricultural and water various liquid such as dripping a jar, chemical plant, laboratory, family and transfer, annotate, allocate system etc., be specially adapted to the maintenance of automobile, agricultural machinery and various motor vehicle, the modulation of agricultural chemicals, fire-fighting equipment medicine and family, and simple in structure, easy to carry, economical and practical, safe and sanitary need not power supply and directly aspirate.

Fig. 2 is Figure 1A-A sectional view.

Fig. 3 is the utility model working principle schematic representation.

1 is container containing among the figure, 2 outlet shutoff valves, and 3 suction pipes, 4 liquid-containers, 5 make things convenient for the pump suction nozzle, 6 liquid

Now in conjunction with further describing embodiment as face: this manually makes things convenient for pump to comprise suction pipe, outlet shutoff valve, make things convenient for pump suction nozzle etc., one end of its suction pipe and outlet shutoff valve are fixing pegs graft, the other end is fixed grafting with making things convenient for the pump suction nozzle, suction pipe adopts the flexible pipe that has the metallic conduction silk, twitch fast to prevent liquid, producing static in the flow process may, outlet shutoff valve is a ball valve, as ending of controlling liquid flow or time-out liquid outflow, making things convenient for the pump suction nozzle is interior round hollow shape, have one can go up in the hollow, the spheroid of low suspension, spheroid with make things convenient for pump suction nozzle inner round wall that certain interval is arranged, and the proportion of spheroid overweights the proportion of liquid, make things convenient for pump suction nozzle top to be provided with the spacing crosspiece of a hollow out, the spacing crosspiece of this hollow out can adopt in-line or cross shape, and the bottom is hollow out also, the diameter of hollow out is less than sphere diameter, and unlikely falling to makes things convenient for outside the pump suction nozzle when falling like this.

When using this manually to make things convenient for pump; earlier the outlet shutoff valve of flexible pipe one end is opened; insert in the container containing; the flexible pipe the other end made things convenient for the pump suction nozzle; insertion has in the container of liquid; go up subsequently; following rapid movement; the spheroid that makes things convenient for hollow in the pump suction nozzle this moment under hydraulic coupling and the liquid level reaction force also with on; following motion; since spheroid with make things convenient for pump suction nozzle inwall that certain interval is arranged; and suction nozzle top is the spacing crosspiece of hollow out; therefore the liquid that whenever the moves upward certain altitude that just from the spacing crosspiece of hollow out on gap and suction nozzle top, upwards flows; then go up repeatedly again; following motion realizes siphon height in liquid level reaches body; liquid just constantly flows out to outlet end; suction makes the spheroid that makes things convenient for hollow in the pump suction nozzle and makes things convenient for hollow out place, pump bottom to maintain certain interval because liquid upwards flows under siphonage; therefore; liquid is constantly flowing; when need not pumping liquid, need only angle of the rotation of the switch on the stop valve; after closing; suction can be suspended or stop in the limit; need only angle of switch rotation when use next time, be in opening state and get final product stop valve.

Claims (3)

1. one kind manually makes things convenient for pump, comprise suction pipe, outlet shutoff valve, one end of suction pipe is fixedlyed connected with outlet shutoff valve, it is characterized in that the pump suction nozzle that makes things convenient for of fixedlying connected with the suction pipe the other end is interior round hollow shape, have in the hollow one can upper and lower suspension spheroid, spheroid with make things convenient for pump suction nozzle inner round wall that certain interval is arranged, and the proportion of spheroid overweights the proportion of liquid, make things convenient for pump suction nozzle top to be provided with the spacing crosspiece of a hollow out, the bottom is hollow out also, and the diameter of hollow out is less than sphere diameter.

2. the pump that manually makes things convenient for according to claim 1 is characterized in that the spacing crosspiece of described hollow out can also be a cross shape.
