The utility model, for solving the problem, is achieved through the following technical solutions:
A kind of water pumper apparatus for demonstrating, comprise the reserve tank of water inlet pipe, rising pipe and upper end open, also comprise the first cylinder, the second cylinder and rocking bar, all be equipped with one in first, second cylinder can slide up and down and piston close-fitting with cylindrical wall, described piston is connected with the piston rod providing power, and described piston rod is in the top of cylinder and be coupling with rocking bar; There is a valve positioner lower end of the first cylinder and the second cylinder respectively by tubes connection, described valve positioner is the hollow cavity of upper and lower opening, the lower end of hollow cavity is provided with inlet valve and is connected with the reserve tank built with aqueous solution by water inlet pipe, and the middle upper end of hollow cavity is provided with drain tap and is connected with rising pipe.
The downside of described rocking bar can be provided with a supporting base, and described supporting base is affixed with rocking bar between two-piston bar.
In such scheme, described inlet valve and drain tap can be the valve that can only upwards open.
For making the clearer job step intuitively arriving each step of water pumper of people, the housing of described first cylinder, the second cylinder and hollow cavity is preferably white clear body.
The beneficial effects of the utility model are:
The utility model water pumper apparatus for demonstrating can demonstrate the principle of work of piston-type water pump, this water pumper apparatus for demonstrating has simple, reliable, the easy to operate feature of structure, and component is transparent directly perceived, with low cost, be specially adapted to the ultimate principle of school of vast middle and primary schools as teaching aid demonstration water pumper, contribute to the understanding of student to this physical knowledge of atmospheric pressure, improve the learning interest of student.
Accompanying drawing explanation
Fig. 1 is the structural representation of this water pumper apparatus for demonstrating.
Number in the figure is: 1, reserve tank; 2, the first cylinder; 3, the second cylinder; 4, valve positioner; 5, conduit; 6, rocking bar; 7, water inlet pipe; 8, rising pipe; 9, piston; 10, supporting base; 11, piston rod; 12, inlet valve; 13, drain tap.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further explained illustrates, but not in order to limit the utility model.
As shown in Figure 1, a kind of water pumper apparatus for demonstrating, comprise the reserve tank 1 of water inlet pipe 7, rising pipe 8 and upper end open, also comprise the first cylinder 2, second cylinder 3 and rocking bar 6, all be equipped with one in first, second cylinder can slide up and down and piston 9 close-fitting with cylindrical wall, described piston 9 is connected with the piston rod 11 providing power, described piston rod 11 is in the top of cylinder and be coupling with rocking bar 6, the downside of described rocking bar 6 is provided with a supporting base 10, and described supporting base 10 is affixed with rocking bar 6 between two-piston bar 11.The lower end of the first cylinder 2 and the second cylinder 3 is connected with a valve positioner 4 respectively by conduit 5, described valve positioner 4 is the hollow cavity of upper and lower opening, in the present embodiment, first cylinder 2 and the second cylinder 3 are connected to the side of hollow cavity respectively by conduit 5, be specifically connected on the wall body between inlet valve 12 and drain tap 13 that is provided with in hollow cavity.
The lower end of described hollow cavity is provided with inlet valve 12 and is connected with the reserve tank 1 built with aqueous solution by water inlet pipe 7, and the middle upper end of hollow cavity is provided with drain tap 13 and is connected with rising pipe 8.In the present embodiment, described inlet valve 12 and drain tap 13 are the valve that can only upwards open.In order to make, people are clearer intuitively arrives each job step of water pumper, and the housing of described first cylinder 2, second cylinder 3 and hollow cavity is preferably white clear body.
The principle of work of this water pumper apparatus for demonstrating is: air is discharged in moving up and down of utilizing piston in cylinder, and causes inner and outer air pressure difference and makes water under gas pressure, rising and extract out:
1) when rocking bar 6 acts on downwards, known by the principle of lever: the piston 9 of the first cylinder 2 presses down, the piston 9 of the second cylinder 3 rises, then now the inlet valve 12 of the first cylinder 2 is closed and drain tap 13 is opened; The drain tap 13 of the second cylinder 3 is closed simultaneously, inlet valve 12 is opened, under the atmospheric effect in the external world, water from water inlet pipe 7 by inlet valve 12 from the hollow cavity flowing to the second cylinder 3 in reserve tank 1, when water level is to the junction of cylinder and hollow cavity, water some from hollow cavity flow to temporary in the second cylinder 3, in addition a part be temporary in hollow cavity;
2) when rocking bar 6 upwards time, known by the principle of lever: the piston 9 of the first cylinder 2 rises, the piston 9 of the second cylinder 3 presses down, then now the drain tap 13 of the first cylinder 2 is closed, inlet valve 12 is opened, under the atmospheric effect in the external world, water from water inlet pipe 7 by inlet valve 12 from the hollow cavity flowing to the first cylinder 2 in reserve tank 1, when water level is to the junction of cylinder and hollow cavity, water some from hollow cavity flow to temporary in the first cylinder 2, in addition a part be temporary in hollow cavity; And now the inlet valve 12 of the second cylinder 3 is closed and drain tap 13 is opened, under the atmospheric effect in the external world, water flows out from the drain tap 13 of hollow cavity, is discharged by rising pipe 8.
By rocking bar 6 upwards, action downwards, and by lever principle, drive the first cylinder 2 and the second cylinder 3 to be ceaselessly cycled to repeat above-mentioned 1), 2) two steps, reach object of constantly drawing water.This apparatus for demonstrating adopts two cover piston-type water pumps to be combined through series connection together, and no matter rocking bar 6 is vertical motion or down maneuver, and each action has water to take out to flow out, and traditional piston-type water pump be upper and lower two is a set of action, just understands water outlet.With traditional piston-type water pump unlike: the utility model can realize operating at full capacity in use, apply in real life will play save strength, raise the efficiency high feature.
