A jet device suitable for physics teaching

Abstract

The invention discloses a jet apparatus suitable for physics teaching. A high-pressure plunger pump is fixedly connected to a water storage tank and a constant water level tank through pipelines. An energy dissipation chamber is disposed inside the constant water level tank and is arranged at the bottom of the constant water level tank. The constant water level tank is fixedly connected to the water storage tank through a drainpipe. A vertical jet device is fixedly connected to the constant water level tank through a first jet pipeline. A vertical nozzle is disposed inside a jet chamber and is fixedly connected to the first jet pipeline. A symmetrical curved surface is disposed inside the jet chamber and is arranged above the vertical nozzle. A physics demonstration device is fixedly connected to the vertical jet device through a second jet pipeline. The jet apparatus suitable for physics teaching employs a constant hydraulic pressure device, so that water can be recycled, the hydraulic pressure is constant, resources are saved, and an environmental protection energy-saving concept is embodied. Energy can be dissipated through glass balls and buffer boards in the energy dissipation chamber which is disposed inside the constant water level tank, so that the water level in the constant water level tank can be stable.

Description

technical field [0001] The invention relates to the technical field of physics teaching appliances, in particular to a jet device suitable for physics teaching. Background technique [0002] In the process of middle school physics teaching, the Torricelli experiment still needs to be realized by inverting the glass tube filled with mercury. It is very dangerous to invert the glass tube filled with mercury. This kind of experiment does not allow students to correctly understand the concept of vacuum. The Magdeburg hemisphere experiment needs to be vacuumed by a vacuum pump. The oil vapor of the vacuum pump in the prior art is a carcinogen, so the whole operation process will pollute the environment in the classroom, which is not good for the physical and mental health of teachers and students. [0003] The prior art has improved the above-mentioned problems, such as a jet device for physics teaching disclosed in the Chinese patent application number CN201120436257.3, the upp...

[0002] In the process of middle school physics teaching, the Torricelli experiment still needs to be realized by inverting the glass tube filled with mercury. It is very dangerous to invert the glass tube filled with mercury. This kind of experiment does not allow students to correctly understand the concept of vacuum

The Magdeburg hemisphere experiment needs to be vacuumed by a vacuum pump. The oil vapor of the vacuum pump in the prior art is a carcinogen, so the whole operation process will pollute the environment in the classroom and be detrimental to the physical and mental health of teachers and students.

[0003] The prior art has improved the above-mentioned problems, such as a jet device for physics teaching disclosed in the Chinese patent application number CN201120436257.3, the upper end of the jet vacuum pump is connected with a vacuum pump tee joint to provide a vacuum Air pumping pipe, the vacuum pumping pipe of the vacuum pump three-way joint is connected with a vacuum gauge through the vacuum meter three-way joint, the end of the vacuum pumping pipe is fixedly connected with the physical demonstration device, and the vacuum on the left side of the physical demonstration device A one-way valve device is arranged on the exhaust pipe, and the extension pipe of the faucet outlet is fixedly connected with the upper port of the vacuum pump tee joint. The faucet is provided with a faucet control handle. The overall structure of the invention is simple, and the operation is convenient and stable. , high reliability, and the use of the invention is beneficial to students' understanding and mastery of physics concepts, but the invention not only cannot make water recycling, waste water resources, consume a lot of energy, and the pressure is unstable, but also has a small scope of application for physics teaching
