Abstract
A water pressure/gas pressure pumping demonstrator, comprising a water container, a sealed pressure reducer, a water absorbing tube and a water discharging tube. The sealed pressure reducer is disposed with two inserting holes, the water absorbing tube and the water discharging tube are respectively inserted into the sealed pressure reducer, wherein the inserting length of the water absorbing tube is longer than one half of depth of the sealed pressure reducer, the sealed pressure reducer is sealed via filling water, with one half depth of the sealed pressure reducer, the sealed pressure reducer is sealed and inversely placed, of which the water absorbing tube is inserted under water level of the water container, the water discharging tube is installed outside of the water container, in order to consequently compose a water pressure/gas pressure pumping demonstrator. The utility model has advantages of simple structure, intuitive demonstration, suitable for demonstration on water pressure/gas pressure principle.
Description
Technical field
The utility model relates to physical teaching aid, particularly relates to a kind of hydraulic pressure air pressure demonstration device that draws water.
Background technology
Utilize the hydraulic pressure air pressure principle of drawing water make to be fit to the water pumper in mountain area, this kind water pumper is extracted into mountain Xia Shui on the mountain and irrigates, can only introduce the principle of drawing water on the classroom, in fact Hydropneumatic water pumping apparatus exists size big, structure is complicated, can not enter the classroom helps classroom instruction, the hydraulic pressure air pressure demonstration device that draws water to help the student deeper to understand principle about the pressure and the air pressure of water.
Summary of the invention
The technical problems to be solved in the utility model provides hydraulic pressure air pressure that a kind of student of help the understands hydraulic pressure air pressure principle demonstration device that draws water.
The technical scheme that adopts is:
A kind of hydraulic pressure air pressure demonstration device that draws water comprises water container, sealing decompressor, suction hose, rising pipe.Described sealing decompressor is provided with two insertion holes, suction hose and rising pipe insert in the sealing decompressor by insertion hole respectively, wherein suction hose insertion length is dark greater than sealing decompressor 1/2nd, the dress water seal, the depth of water is sealing decompressor 1/2nd, and with described sealing decompressor sealing and inversion, its suction hose inserts the water surface below of water container, rising pipe is contained in water container outside, constitutes a kind of hydraulic pressure air pressure demonstration device that draws water.
Above-mentioned suction hose and rising pipe all are equipped with retaining valve.
The utlity model has advantage simple in structure, directly perceived, as to be fit to the theory teaching of water pressure, atmospheric pressure.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
A kind of hydraulic pressure air pressure demonstration device that draws water comprises water container 1, sealing decompressor 2, suction hose 3, rising pipe 4.Described sealing decompressor 2 is provided with two insertion holes, suction hose 3 and rising pipe 4 insert in the sealing decompressor by insertion hole respectively, wherein suction hose 3 insertion length are dark greater than sealing decompressor 1/2nd, the dress water seal, the depth of water is sealing decompressor 1/2nd two, with described sealing decompressor sealing and inversion, its suction hose 3 inserts on the water surface of water container 1, rising pipe 4 is contained in water container 1 outside, and suction hose 3 and rising pipe 4 all are equipped with retaining valve 5, constitutes a kind of hydraulic pressure air pressure demonstration device that draws water.
Principle of work:
When open check valve 5, sealing decompressor 2 first halves are pressure reduction space, and its pressure is less than atmospheric pressure, and the water of water container 1 promotes water at atmospheric pressure and rises along suction hose 3, and produces fountain.
