Abstract
The utility model relates to an experimental apparatus. The experimental apparatus comprises a bracket and a base which are integrally molded, and the bracket is provided with scales. The experimental apparatus is characterized in that the experimental apparatus further comprises a funnel which is integrally molded with a water pipe, and the other end of the water pipe is connected with a sprayer; the water pipe is divided into two parts including a hosepipe and a hard pipe, wherein the hosepipe is connected with the funnel and the hard pipe is connected with the sprayer; and a water pressure test bar is arranged on the bracket and corresponds to the position between the sprayer and the funnel. The experimental apparatus has the advantages that the structure is simple, students can know the changing regularity of water pressure through experiments, and the interests of the students on scientific discovery and research can be aroused.
Description
Technical field
The utility model relates to a kind of experimental provision.
Background technology
Existing junior middle school physics teaching does not also have the device of hydraulic pressure test, and teacher generally by the explanation of the example in the daily life, allows the student understand the knowledge of this respect, and like this, the effect of study is not so good.
The utility model content
The purpose of this utility model provides a kind of experimental provision of testing hydraulic pressure, and the technical scheme of taking is: this experimental provision comprises a support and a base, this support and base are integrated, be carved with scale on this support, it is characterized in that: also comprise a funnel, funnel and water-supply-pipe are one-body molded, the other end of water-supply-pipe is connected with shower nozzle, water-supply-pipe is divided into two parts, and a part is a flexible pipe, and a part is a hard tube, wherein the flexible pipe part is connected with funnel, and the hard tube part is connected with shower nozzle; On the support corresponding to the position between shower nozzle and the funnel place height, be provided with the hydraulic pressure test bar.
Funnel is fixed on arbitrary height by the live splint on the support.The position that joins at funnel and water-supply-pipe is provided with switch valve.
The hard tube of this water-supply-pipe partly is the U type, is used for supporting shower nozzle.
Advantage of the present utility model is: simple in structure, and can allow the student vividly understand the Changing Pattern of hydraulic pressure by experiment, cause the interest of student to scientific discovery research.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment.
Embodiment
This experimental provision comprises a support 1, with a base 2, this support and base are integrated, are carved with scale on this support, it is characterized in that: also comprise a funnel 3, funnel and water-supply-pipe 4 are one-body molded, and the other end of water-supply-pipe is connected with shower nozzle 5, and water-supply-pipe is divided into two parts, a part is a flexible pipe, a part is a hard tube, and wherein the flexible pipe part is connected with funnel, and the hard tube part is connected with shower nozzle; On the support corresponding to the position between shower nozzle and the funnel place height, be provided with hydraulic pressure test bar 6.
Funnel is fixed on arbitrary height by the live splint on the support 8.The position that joins at funnel and water-supply-pipe is provided with switch valve 7.
The hard tube of this water-supply-pipe partly is the U type, is used for supporting shower nozzle.
During use, existing the valve of flexible pipe is tightened, funnel is full of the water of constant weight, funnel is fixed on the height of setting.Open valve then, by the pressure release of water, water can impact reference test bar, according to the height of regulating reference test bar, determines the size of hydraulic pressure.
