Abstract
The utility model relates to a fluid pressure demonstrates appearance mainly includes transparent basin and a breather pipe, and the breather pipe both ends are connected with that two sizes are the same to have elastic bobble, and the design of breather pipe middle part has the air inlet, is stamped sealed lid on the air inlet. The utility model discloses simple structure, convenient operation, through experiment demonstration, transfer student's interest in learning, the help student understands the existence of mastering liquid internal pressure pressure.
Description
Technical field
The utility model relates to a kind of teaching and experiment equipment, particularly relates to a kind of fluid pressure demonstration instrument.
Background technology
At present in primary school nature science or middle school physical curriculum, there is the instruction of pressure pressure about liquid internal, comparatively abstract and be not easy by student's understand and master, therefore become a difficult point in teaching always.Therefore, propose a kind of demonstration instrument of the education experiment for this aspect, student observes by experiment, and getting final product visual in image ground understand and master focal points, is very necessary.
Summary of the invention
The purpose of this utility model is to solve in middle and primary schools' teaching, is difficult to explanation and knows that liquid internal exists the problems such as pressure pressure, provides a kind of structure simple, demonstrates teaching and experimental demonstration instrument easily.
The utility model is realized by following measures: a kind of fluid pressure demonstrator, mainly comprise transparent tank and a snorkel, snorkel two ends are connected with that two sizes are identical has flexible bead, be designed with air intake opening, air intake opening is stamped gland bonnet in the middle part of snorkel.
The utility model structure is simple, easy to operate, demonstrates by experiment, the learning interest of mobilizing students, helps the existence of student's understand and master liquid internal pressure pressure.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
embodiment:
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1, a kind of fluid pressure demonstrator, mainly comprises transparent tank 1 and a snorkel 2, snorkel 2 two ends are connected with two identical beads 3 of size, and two beads 3 are made into by flexible material, are designed with air intake opening in the middle part of snorkel 2, air intake opening are stamped gland bonnet 4.
During use, inject liquid, be blown into air at air intake opening at transparent tank 1, namely two beads 3 expand and become large, and size is identical.Cover tightly gland bonnet 4, pick up a wherein bead 3 and slowly insert in tank 1 liquid, the bead 3 in tank 1, toward bottom land sinking watching, will progressively diminish, and the bead 3 outside tank 1 slowly becomes large.Illustrate thus, there is pressure pressure in tank 1 liquid and bead 3 in groove is diminished, air goes to bead 3 groove from bead in groove 3, makes the outer bead 3 of groove become large.
Claims (2)
1. a fluid pressure demonstrator, is characterized in that: mainly comprise a transparent sink and a snorkel, and snorkel two ends are connected with that two sizes are identical has flexible bead, be designed with air intake opening, air intake opening is stamped gland bonnet in the middle part of described snorkel.
2. a kind of fluid pressure demonstrator according to claim 1, is characterized in that: two described beads, and a bead is inserted in the liquid of transparent sink, and one is placed on outside transparent sink.
