The utility model has the advantages that compared with the prior art, the utility model adopts the transparent straight pipe section for replacing U-shaped double pipes, the liquid pressure intensity is enlarged when the liquid level rises, the liquid pressure intensity is reduced when the liquid level falls down, and the change results of the pressure intensity is intuitive, and can be easily accepted by students. Compared with a small single-film box in the prior art, the utility model is provided with two rubber films, in addition, the dimension is large, and the defection effect is obvious.
Description
Technical field
The utility model relates to a kind of hydraulic detection device, relates in particular to a kind of hydraulic pressure detecting device that is applied in student experimenting, teacher's demonstration " liquid internal pressure " physical phenomenon experimental technique.
Background technology
In student experimenting, teacher demonstration " liquid internal pressure " physical phenomenon experimental technique, generally be to adopt " U " type pipe hydraulic ga(u)ge, the experimental phenomena according to the variation of two liquid level differences proves the variation of liquid internal pressure size, its shortcoming is:
1, for the classmate of difficulty of learning, the result of variations of pressure size is directly perceived inadequately, accepts comparatively difficulty.Change rubber diaphragm towards the time, the liquid level registration changes emulsion tube in " U " type pipe hydraulic ga(u)ge because of bending causes, classmates easily draw " the same degree of depth of liquid internal place does not wait to the pressure of all directions " mistake conclusion;
2, the deformation of rubber membrane is obvious inadequately, teacher's demonstration: because the deformation of rubber membrane when causing the experiment of the variation of two liquid level differences in " U " type pipe hydraulic ga(u)ge, is sitting in the deformation that front-seat classmate can't see rubber membrane clearly, also can only listen teacher to give an oral account passively.
The utility model content
In order to address the above problem, the utility model provides a kind of hydraulic pressure detecting device, the tangible inadequately problem of deformation directly perceived inadequately with the result of variations that solves pressure size of the prior art, rubber membrane.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of hydraulic pressure detecting device comprises a container, and described container is provided with vent port, it is characterized in that, described container comprises liquid container main body and the transparent straight pipe section that is arranged on the liquid container main body, and described transparent straight pipe section is provided with scale; The sidewall of described liquid container main body is provided with the film with flexible ability.
Described vent port is arranged on the top of described transparent straight pipe section.
Described container is provided with a gas outlet, and described gas outlet is provided with described vent port.
The internal diameter of described transparent straight pipe section is 3mm-6mm.
Described film is a rubber membrane.
Described liquid container main body is the cylindricality round barrel shape, respectively is provided with a film on the pair of sidewalls of described liquid container main body.
Described liquid container main body is Fang Tizhuan.
Described container is a transparent vessel.
The beneficial effects of the utility model:
Compared with prior art, it is two-tube that the utility model adopts a transparent straight pipe section to substitute " U " type, and liquid pressure is big when liquid level rises, and liquid pressure is little when liquid level descends, and the result of variations of pressure size very intuitively is easier to the student and receives.
Compare with " the monofilm capsule " of prior art, two rubber membranes are arranged in the utility model, and size is bigger, deformation effect is clear.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is a structural representation of the present utility model.
The right view of Fig. 2 Fig. 1.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1 and 2, a kind of hydraulic pressure detecting device comprises a container 100, and container 100 is a transparent vessel.Described container 100 comprises liquid container main body 110 and the transparent straight pipe section 120 that is arranged on the liquid container main body 110, and this transparent straight pipe section 120 is provided with scale 121.The internal diameter of transparent straight pipe section 120 is 3mm-6mm.
In the present embodiment, liquid container main body 110 is cylindricality round barrel shape (Fang Tizhuan or other shape all can), respectively is provided with a film 111 with flexible ability on the pair of sidewalls of liquid container main body.This film 111 can be rubber membrane.This film 111 is of a size of 3cm*3cm.
Container is provided with vent port, and in the present embodiment, container is provided with a gas outlet 130, and gas outlet 130 is provided with described vent port 131.On this vent port 131, be with a hood 132.Certainly, also vent port can be arranged on the top of transparent straight pipe section 120.
Using method of the present utility model:
1. in a tank, inject an amount of water.
2. open the hood of hydraulic pressure detecting device, in the hydraulic pressure detecting device, inject blue liquid, liquid level reset scale mark.
In the water with hydraulic pressure detecting device submergence tank, observe the rubber membrane variation that liquid level position takes place in liquid internal different depth transparent straight pipe section? rubber membrane pressurized generation deformation degree?
Experimental phenomena: intraluminal fluid face lifting height, rubber membrane sinking degree increase with liquid depth.
Preliminary conclusion: in density liquid of the same race, the pressure that liquid produces increases with liquid depth.
3. the hydraulic pressure detecting device is immersed in the liquid of different densities, observes rubber membrane in the same degree of depth of liquid internal
The variation that liquid level position takes place in the transparent straight pipe section? rubber membrane pressurized generation deformation degree?
Experimental phenomena: liquid level lifting height, rubber membrane sinking degree increase with density of liquid.
Preliminary conclusion: at the same degree of depth of liquid internal place, the pressure that liquid produces increases with density of liquid.
The utility model is simple in structure, and is easy to use.Compared with prior art, it is two-tube that the utility model adopts a transparent straight pipe section to substitute " U " type, liquid pressure is big when liquid level rises, liquid pressure is little when liquid level descends, only need variation according to the liquid level lifting height, can judge the variation of liquid internal pressure, more directly perceived, be easier to the student and receive.
Compare with " the monofilm capsule " of prior art, two rubber membranes are arranged in the utility model, and size is bigger, deformation effect is clear.
More than show and described ultimate principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in the foregoing description and the instructions is principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in the claimed scope of the present utility model.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
