Problems solved by technology

[0002] The development of fluid mechanics plays an important role in the development of modern industrialization. Almost all heavy machinery and equipment inevitably need to use the relevant scientific theories of fluid mechanics. However, the teaching of fluid mechanics is quite boring and interactive, and it is difficult to stimulate students interest, which limits the improvement of the teaching efficiency of fluid mechanics

Embodiment 1

[0019] The fluid mechanics teaching equipment that entertains and educates is characterized by: including the first hydraulic cylinder G1, the second hydraulic cylinder G2, the adjustable valve F, the one-way valve DXF, the first handle L1, the second handle L2, and liquid;

[0020] The first hydraulic cylinder G1 has a first piston S1;

[0021] The second hydraulic cylinder G2 has a second piston S2;

[0022] The first hydraulic cylinder G1 communicates with the second hydraulic cylinder G2 via the adjustable valve F;

[0023] The first hydraulic cylinder G1 communicates with the second hydraulic cylinder G2 via the one-way valve DXF;

[0024] The flow restriction direction of the one-way valve DXF is to allow the fluid of the second hydraulic cylinder G2 to flow into the first hydraulic cylinder G1 through the one-way valve DXF, and not to allow the fluid of the first hydraulic cylinder G1 to flow into the second hydraulic cylinder G2 through the one-way valve DXF ;

Abstract

This fluid mechanics teaching equipment for teaching through lively activities comprises a first hydraulic cylinder (G1), a second hydraulic cylinder (G2), an adjustable valve (F), a check valve (DXF), a first handle (L1), a second handle (L2) and liquid. The first hydraulic cylinder (G1) is provided with a first piston; the second hydraulic cylinder is provided with a second piston; the first hydraulic cylinder (G1) is communicated with the second hydraulic cylinder through an adjustable valve (F); the first hydraulic cylinder is communicated with the second hydraulic cylinder through a one-way valve; the flow direction of the one-way valve is limited as follows: liquid in the second hydraulic cylinder is allowed to flow into the first hydraulic cylinder through the one-way valve; the flow of the adjustable valve is adjustable, and the adjustable valve (F) can be completely closed; the first handle is connected with a first piston of the first hydraulic cylinder; the second handle isconnected with a second piston of the second hydraulic cylinder; and liquid is poured into the first hydraulic cylinder and the second hydraulic cylinder. The teaching equipment is low in cost and canimprove the teaching efficiency.

Description

technical field [0001] The invention belongs to the field of fluid mechanics teaching, and specifically designs fluid mechanics teaching equipment that combines teaching and entertainment. Background technique [0002] The development of fluid mechanics plays an important role in the development of modern industrialization. Almost all heavy machinery and equipment inevitably need to use the relevant scientific theories of fluid mechanics. However, the teaching of fluid mechanics is quite boring and interactive, and it is difficult to stimulate students interest, which limits the improvement of fluid mechanics teaching efficiency. Contents of the invention [0003] In order to overcome the above problems, the present invention designs a fluid mechanics teaching equipment that entertains and educates. [0004] The specific plan is: fluid mechanics teaching equipment that entertains and educates, including the first hydraulic cylinder G1, the second hydraulic cylinder G2, th...
