Description

The hand high-pressure water pump of family expenses

Affiliated technical field

The utility model relates to a kind of improvement of family expenses hand water pump, and it is applicable to family's water intaking, the sprinkling irrigation in farmland and orchard.

Technical background

Piston type domestic water pump uses considerably general in the rural area, it simple in structure, cheap, easy to use, easily damaged parts occurs often, increase many troubles to the user, for this reason, constantly there is the people that relevant technology is proposed improvement project, for example, Chinese patent CN03236300.1 number it comprises handgrip about " high pressure manual water pump ", the pump housing, the pump housing is by base, steel bushing is formed up and down, last steel bushing is connected with following steel bushing bolt, and following steel bushing is connected with bolt of lower base, and handgrip is installed in a side of the pump housing, base is communicated with pumped well, press fork one end and handgrip to flexibly connect, the other end and push rod flexibly connect, and push rod is positioned at the outside of steel bushing on the pump housing, its top and piston rod are movably connected, the piston rod the other end is connected with piston, and places in the pump housing, check valve is housed in the base protects frame, check valve protects check valve in the frame, base exterior also is provided with water inlet, water outlet, the water outlet upper and lower settings be two with the pump housing in communicate.This water pump operation is light, and pressure is big, but easily damaged parts appears in complex structure easily.

Summary of the invention

Task of the present utility model is to provide a kind of family expenses hand high-pressure water pump, and this water pump operation is light, and pressure is big, the lift height, and long service life, high working efficiency, rational in infrastructure, can apply in vast rural area.

Task of the present utility model is to carry out in such a way, in the pump housing of the hand high-pressure water pump of this family expenses upper piston and lower piston are housed, upper piston is made of punch holder and die holder and the rubber disk in the middle of their, and lower piston is made of punch holder and die holder and the rubber disk in the middle of their, the punch holder of upper piston is bigger than die holder, and the punch holder of lower piston is littler than die holder, and intake pipe and outlet pipe all are equipped with check valve.Work as piston rod like this and move up under the drive of handle, the rubber disk of lower piston is bent downwardly, and the rubber disk of upper piston also is bent downwardly, and upper piston is not worked, and lower piston work drinks up well water; When piston rod moved down under handle drives, rubber ring in the lower piston and the rubber disk in the upper piston were bent upwards, and upper piston work is pressed onto the well water that drinks up in another outlet pipe and goes, and lower piston is not worked.In the pump housing bottom intake pipe and an outlet pipe are arranged, and at intake pipe and outlet pipe place a check valve is housed all, do not allow well water produce the refluence phenomenon, thereby realize improving hydraulic pressure, its lift can reach more than 10 meters.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is the hand high-pressure water pump sectional views of family expenses of the present utility model.

Among the figure 1, handle, 2, piston rod, 3, support, 4, the pump housing, 5, intake pipe, 6, outlet pipe, 7, upper piston; 8, lower piston, 9, punch holder, 10, die holder, 11, punch holder, 12, die holder, 13,14, the rubber disk, 15,16, check valve.

Embodiment

As we know from the figure, the hand high-pressure water pump of this family expenses is by handle (1), piston rod (2), support (3), the pump housing (4), intake pipe (5) and outlet pipe (6) are formed, handle (1) and support (3), piston rod all flexibly connects between (2), upper piston (7) and lower piston (8) are housed in the pump housing (4), upper piston (7) is made of punch holder (9) and die holder (10) and the rubber disk (13) in the middle of their, and lower piston (8) is made of punch holder (11) and die holder (12) and the rubber disk (14) in the middle of their, the punch holder (9) of upper piston (7) is bigger than die holder (10), and the punch holder (11) of lower piston (8) is littler than die holder (12), upper piston (7) is different with the effect of lower piston (8) like this, when handle (1) drives piston rod (2) when moving up, the rubber disk (13) of upper piston (7) is bent downwardly, do not produce active force between the upper piston (7) and the pump housing (4), because the die holder (10) of upper piston (7) is little, leave the space each other, otherwise the rubber disk (14) of lower piston (8) also is bent downwardly, and the die holder (12) of lower piston (8) is big, they and the pump housing (4) do not interspace each other, well water will move up and rises along with piston rod (2), so lower piston (8) plays the water intaking function; When handle (1) drives piston rod (2) when moving down, the rubber disk (13) of upper piston (7) is bent upwards, because its punch holder (9) is bigger than die holder (10), the pump housing (4) and rubber disk (13) and punch holder (9) drive fit, upper piston (7) produces active force like this, flow to outlet pipe (6) after well water is under pressure and transfer out, at this moment the rubber disk (14) of lower piston (8) also is bent upwards, because the punch holder (11) of lower piston (8) is little, also leave the space between the lower piston (8) and the pump housing (4), so lower piston (8) does not produce active force, upper piston (7) plays the setting-out function.Because intake pipe (5) is equipped with check valve (15), outlet pipe (6) is equipped with another check valve (16), so well water can not flow backwards.The hand high-pressure water pump of this family expenses rational in infrastructure, easy to use, lift can reach more than 10 meter, and working efficiency improves greatly, and prolong working life.

Claims (1)

1. one kind by handle (1), piston rod (2), support (3), the pump housing (4), the hand high-pressure water pump of family expenses that intake pipe (5) and outlet pipe (6) are formed, it is characterized in that: upper piston (7) and lower piston (8) are housed in the pump housing (4), upper piston (7) is made of punch holder (9) and die holder (10) and the rubber disk (13) in the middle of their, and lower piston (8) is made of punch holder (11) and die holder (12) and the rubber disk (14) in the middle of their, the punch holder (9) of upper piston (7) is bigger than die holder (10), and the punch holder (11) of lower piston (8) is littler than die holder (12), intake pipe (5) is equipped with check valve (15), and outlet pipe (6) is equipped with another check valve (16).
