Abstract
The utility model relates to a demonstrator for relationship between liquid pressure and range, which comprises a water trough, a supporting frame, a water tank and a water container. The water trough is of a strip-shaped trough body with an opening at the top; one end of the water trough is vertically provided with the supporting frame; the water tank is horizontally arranged on the supporting frame; a mounting container is fixed between the water tank and the water trough; the bottom surface of the water tank is communicated with the container through a water pipe, and the surface of the water pipe is provided with a water stopping clamp; the side surface of the container is provided with a row of permeable holes from upside to downside, the top of the side surface of the container is movably connected with a pressure rod, and hole plugs are respectively installed on the inner side surface of the pressure rod corresponding to the permeable holes; scale length is arranged along the surface of the water trough; the surface of the container is provided with volume scales. The water tank is additionally provided with a water-filling pipe, the other end of the water filling pipe is connected with a water faucet. A water discharge pipe is communicated on the container closing to the top, and the other end of the water discharge pipe is inserted into the water trough. The demonstrator has advantages of reasonable structure, simple operating, good process and obvious effect.
Description
Technical field the utility model relates to a kind of experimental facilities, especially a kind of liquid pressure and range relation demonstration instrument.
Background technology is in senior middle school physics teaching, teachers and students need to do the experiment of liquid pressure and range relation, in experimentation, because present teaching aid is simple and crude and situation such as complex operation, therefore bigger to the experimental result influence, often cause low, the weak effect of experimental result precision.
The summary of the invention the purpose of this utility model provides a kind of liquid pressure and range relation demonstration instrument of observing and demonstrating be convenient to.
The utility model comprises tank, bracing frame, water tank and dress hydrophone ware, and tank is open-topped strip cell body, and bracing frame at one end vertically is installed, and sets up water tank in the bracing frame level; Fixedly mount vessel between water tank and tank, water tank bottom surface and vessel are connected by water pipe, and the water pipe surface is provided with tongs; Offer row's permeable hole in the vessel side from top to bottom, and flexibly connect depression bar in the vessel side top, the corresponding permeable hole of depression bar inner surface position processes stopple respectively; Along flume surface marking length scale; In vessel surface marking containing mark.Water tank is established water injection pipe in addition, and the water injection pipe other end is connected with water swivel.Connect a drainpipe at vessel near the place, top, the drainpipe other end inserts tank.
After adopting said structure, when experiment was used, the user clamped tongs earlier, injected an amount of water to water tank again.Open tongs then, make the water in the water tank flow to vessel along water pipe, and spray from the permeable hole of vessel side, the user writes down the distance of water column ejection and finishes laboratory report; The water column of ejection falls in the tank of below, avoids drenching table top.Vessel can enter tank to superfluous water near the drainpipe at top, keep the water surface in the vessel certain.
The utility model has the advantages that: rational in infrastructure, easy and simple to handle, technology is exquisite, effect is obvious, presentation time is long, also can keep testing health.
Description of drawings Fig. 1 is a planar structure sketch of the present utility model.
Embodiment is shown in Fig. 1 planar structure sketch of the present utility model, the utility model comprises tank 1, bracing frame 2, water tank 3 and dress hydrophone ware 4, tank is open-topped strip cell body, and bracing frame at one end vertically is installed, and sets up water tank in the bracing frame level; Fixedly mount vessel between water tank and tank, water tank bottom surface and vessel are connected by water pipe 5, and the water pipe surface is provided with tongs 6; Offer row's permeable hole 7 in the vessel side from top to bottom, and flexibly connect depression bar in the vessel side top, the corresponding permeable hole of depression bar inner surface position processes stopple 8 respectively; Along flume surface marking length scale 9; In vessel surface marking containing mark 10.Water tank is established water injection pipe 11 in addition, and the water injection pipe other end is connected with water swivel.Connect a drainpipe 12 at vessel near the place, top, the drainpipe other end inserts tank.
