Throttle type laminar experiment pressure stabilizer and method thereof

Abstract

The invention discloses a throttle type laminar experiment pressure stabilizer and a method thereof. The throttle type laminar experiment pressure stabilizer is provided with a water pump outlet pipe, a valve with at least one orifice, a pressure stabilizing tank and an experimental pipeline water supply pipe, wherein one or more orifices are formed in a valve plate of the valve. When the valve is fully opened, pressure water led from a water pump before the valve flows to an experimental pipeline through the orifices. When the small flow flows through the orifices, water pressure fluctuations caused by the water pump before the valve can be preferably eliminated by the orifices, so as to achieve good fluctuation eliminating and pressure stabilizing effects. The secondary pressure stabilization is performed through the pressure stabilizing tank, so that the pressure stabilizing precision is within plus or minus 0.5 millimeters, therefore, the laminar experiment pressure stabilizing water supply requirement can be satisfied under the condition of direct supply of the water pump, and the laminar experiment stabilizing problem which is difficult to solve for a long time under the condition of direct supply of the water pump is solved. The pressure stabilizer has the advantages of simple structure, convenience in operation and low cost and can also be used in small flow systems with high pressure stabilizing performance requirements.

Description

technical field [0001] The invention relates to a teaching experiment instrument. In particular, it relates to a throttling laminar flow experimental voltage stabilizer and a method thereof. Background technique [0002] In the teaching experiment of fluid mechanics and hydraulics, the along-path resistance experiment is a basic experiment item widely used in colleges and universities. The resistance tester used in it is usually directly supplied by a water pump, which is a self-circulating water supply tester. Due to the pressure fluctuation in the self-circulating pipeline system caused by the water pump of this experimental instrument, the accuracy and stability of the experiment will be seriously affected. The following is an example of the traditional along-line resistance tester of 7 mm experimental pipeline to illustrate its technical background. The technical data involved in the following descriptions are all based on this example. [0003] The resistance tes...

AI Technical Summary

Problems solved by technology

This voltage stabilization method has the following two problems: one is that the pressure-resistant requirements of the pressure-stabilizing tank are high, and the manufacturing cost of the tank is high; the other is that there is no such tank that can meet the pressure-stabilizing requirements in the market.

An experimental instrument with a pressure fluctuation of more than 2 mm cannot meet the requirements of teaching experiments.
