Embodiment 1

[0039] Such as Figure 1-3 As shown, the teaching demonstration equipment of one-way valve principle for entertaining and entertaining includes demonstration valve F, right hydraulic cylinder G-Y, left hydraulic cylinder G-Z, right handle L-Y, left handle L-Z; right hydraulic cylinder G-Y has right piston S-Y; The cylinder G-Z has a left piston S-Z; the right handle L-Y is connected with the right piston S-Y of the right cylinder G-Y; the left handle L-Z is connected with the left piston S-Z of the left cylinder G-Z;

[0040] Demonstration valve F includes main chamber F-F, left chamber F-Z, right chamber F-Y, left bell mouth F-Z1, right bell mouth F-Y1, right port F-Y2, left port F-Z2, valve ball F-Q; main chamber F-F The left side communicates with the big end of the left bell mouth F-Z1; the right side of the main chamber F-F communicates with the big end of the right bell mouth F-Y1; the right interface F-Y2 communicates with the small end of the right bell mouth F-Y1; the...

Embodiment 2

[0066] Such as Figure 4 As shown, improvements are made on the basis of Example 1. The valve ball F-Q of the demonstration valve F is a multi-layer ball, the outer layer is a rubber layer F-Q-XJC, and the inner layer is an iron core F-Q-TX, and the iron core F-Q-TX has a cavity T-Q-KX; reduce the cracking pressure of demonstration valve F one-way conduction function.

Embodiment 3

[0068] The one-way valve principle teaching and demonstration equipment for entertaining and entertaining described in the embodiment is used for training teaching institutions to carry out teaching and training.

Abstract

The invention discloses a fluid mechanics teaching method for a training teaching institution. One-way valve principle teaching demonstration equipment for teaching through lively activities is used for teaching contents in the training teaching institution. The one-way valve principle teaching demonstration equipment for teaching through lively activities comprises a demonstration valve (F), a right hydraulic cylinder (G-Y), a left hydraulic cylinder (G-Z), a right handle (L-Y) and a left handle (L-Z). The right hydraulic cylinder (G-Y) is provided with a right piston (S-Y); the left hydraulic cylinder (G-Z) is provided with a left piston (S-Z); the right handle (L-Y) is connected with a right piston (S-Y) of the right hydraulic cylinder (G-Y); and the left handle (L-Z) is connected witha left piston (S-Z) of the left hydraulic cylinder (G-Z). The method is low in cost and can improve the teaching efficiency.

Description

technical field [0001] The invention belongs to the field of fluid mechanics teaching, and in particular relates to a fluid mechanics teaching method for training and teaching institutions. 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. [0003] The check valve is an important part of the fluid mechanics device. The application of the check valve in the automation system is very extensive and very important. It is necessary to explain it as a key point. [0004] However, the application teaching of fluid mechanics is rather boring and interactive, which is difficult to arouse students' interest and limits the improvement of fluid mechanics teaching efficiency. Contents of the invention [0005] In order to overcome the above problems, the present invention designs a fl...
