Abstract
The utility model belongs to the field of physics teaching aids and particularly relates to a simple pressure gauge. The simple pressure gauge is characterized in that the other end of a U-shaped glass pipe is communicated with a right cavity body of a cube box through a rubber pipe, and the left cavity body and the right cavity body of the cube box are separated into independent cavity bodies through a partition plate. Therefore, the simple pressure gauge has the advantages of simple structure and accurate experimental result.
Description
Technical field: the utility model belongs to physics teaching apparatus field, is specifically related to a kind of simple and easy piezometer.
Background technology: at present, the piezometer of physics student experiment usefulness is made up of the circular box of rubber diaphragm sealing by a proofed sleeve and " U " type glass tube, when equating, all directions pressure need rotate circular box at the same degree of depth liquid of research, make rubber membrane up, down, towards the side, the same degree of depth is difficult for grasping when rotating, liquid level in " U " type glass tube can change, and can not accurately reach a conclusion.
Summary of the invention: the purpose of this utility model provides a kind of simple in structure, the simple and easy accurately piezometer of experimental result.
The technical solution of the utility model is: a kind of simple and easy piezometer, form by the cube box of rubber diaphragm sealing by being fixed in " U " type glass tube and the both sides that interior dress on the support has color water, " U " type glass tube one end is communicated with cube box left cavity body by proofed sleeve, it is characterized in that: " U " type glass tube other end is communicated with cube box right cavity body by proofed sleeve, and left and right cavity is separated into individual cavity by dividing plate.
Owing to adopt technique scheme, studying liquid internal when all directions pressure equates, the cube box is put into the beaker that fills water, the rubber membrane of two sides of cube box is in the same degree of depth in the liquid, the film sinking degree that can observe two sides is identical, the liquid level of " U " type glass tube is also identical, rotate the direction of cube box, also can draw same result, this has proved two sides, the cube left and right sides suffered liquid pressure direction difference, but the conclusion that pressure equates, thereby have simple in structurely, experimental result is advantage accurately.
Description of drawings: come the technical solution of the utility model is described in further details below in conjunction with the drawings and specific embodiments.
Accompanying drawing is a structural representation of the present utility model.
Embodiment: with reference to the accompanying drawings.A kind of simple and easy piezometer has " U " type glass tube 2 of color water and the cube box that both sides are sealed by rubber diaphragm by the interior dress that is fixed on the support 1
Form, " U " type glass tube 2 one ends pass through proofed sleeve
Be communicated with cube box 4 left cavitys, " U " type glass tube 2 other ends are communicated with cube box 4 right cavitys by proofed sleeve 5, and left and right cavity is separated into individual cavity by dividing plate.
