Abstract
The invention discloses a kind of Reynolds experiment device color water flow two-stage regulating devices, including the infusion regulator being arranged in liquid pipe and the plastic spiral regulating valve that liquid pipe lower end is arranged in.Reynolds experiment device color water flow is adjusted control mode and is improved to two-stage by single-stage by the present invention, solve single-stage and adjust that the operation of control mode difficulty, error is more, failure is more, the defect of maintenance difficulty etc., have many advantages, such as that adjusting control mode is easy to operate, malfunction less, failure is few, maintenance is easy, it is at low cost, flexible for installation, draw materials it is convenient；Meanwhile the included color water of structure of the invention goes out water needle head and blocks maintenance function.
Description
Technical field
The present invention relates to experimental provision fields, and in particular to a kind of Reynolds experiment device color water flow two-stage adjusting dress
It sets.
Background technique
Reynolds experiment device is Reynolds number and the frictional head loss etc. measured under different fluidised forms of the color water in flow tube
Device the understanding to pipe stream difference fluidised form is deepened by the analysis of the different conditions to color water in pipe, grasp laminar flow,
The kinematics characteristic and kinetic characteristics of turbulent two kinds of fluidised forms.And color water enters flow, flow velocity, fineness of flow tube etc. is
The key of the experiment, so the superiority and inferiority that color water flow adjusts control element plays very important effect, currently, existing thunder
Color water flow used by promise experimental provision adjusts the generally existing following defect of control element:
(1) color water flow adjusts control mode as single-stage control, and method is single；
(2) being out of order, probability is big, maintenance load is more, is the bottleneck of reynolds experiment；
(3) operation difficulty is big, is easy error；
(4) method for maintaining is backward, maintenance mode is single, maintenance process is complicated.
Summary of the invention
To solve the above problems, being adopted the present invention provides a kind of Reynolds experiment device color water flow two-stage regulating device
With two-step evolution, composition is simple, and increased costs are seldom, and operation is simpler, and maintenance is more convenient, convenient for operation implementation.
To achieve the above object, the technical scheme adopted by the invention is as follows:
A kind of Reynolds experiment device color water flow two-stage regulating device, including the infusion regulator being arranged in liquid pipe and sets
Set the plastic spiral regulating valve in liquid pipe lower end.
When two-stage regulating device of the invention is adjusted, the unlatching of fixed first order adjusting control valve, that is, plastic spiral regulating valve
Degree, generally standard-sized sheet make its lumen become larger or become smaller to adjust stream by the regulating wheel extruding liquid pipe on sliding infusion regulator
Measure flow velocity.
When the needle tubing of two-stage regulating device of the invention blocks maintenance, the open degree of fixed plastics adjustable diameter and screw adjusting valve, generally
For standard-sized sheet, liquid pipe is squeezed by the regulating wheel on sliding infusion regulator, so that its intraluminal pressure is become larger or is become smaller, to make
It must block in needle tubing and positive pressure or negative pressure occur, dredge syringe needle.
The invention has the following advantages:
Reynolds experiment device color water flow is adjusted into control mode, two-stage is improved to by single-stage, solved single-stage and adjust controlling party
The operation of formula difficulty, error is more, failure is more, the defect of maintenance difficulty etc., has that adjusting control mode is easy to operate, malfunction less, failure is few, ties up
Repair the advantages that easy, at low cost, flexible for installation, materials facilitate；Meanwhile the included color water of structure of the invention goes out water needle head and blocks dimension
Repair function.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of traditional Reynolds experiment device.
Fig. 2 is the structural schematic diagram of the embodiment of the present invention.
Fig. 3 is the scheme of installation of infusion regulator in the embodiment of the present invention.
In figure: 1- liquid pipe；2- infusion regulator；3- plastic spiral regulating valve；4- color water water storage cup；5- water storage tank.
Specific embodiment
The present invention is described in detail combined with specific embodiments below.Following embodiment will be helpful to the technology of this field
Personnel further understand the present invention, but the invention is not limited in any way.It should be pointed out that the ordinary skill of this field
For personnel, without departing from the inventive concept of the premise, various modifications and improvements can be made.These belong to the present invention
Protection scope.
As shown in Fig. 2-Fig. 3, adjusts and fill the embodiment of the invention provides a kind of Reynolds experiment device color water flow two-stage
It sets, including the infusion regulator 2 being arranged in liquid pipe 1 and the plastic spiral regulating valve 3 of 1 lower end of liquid pipe is set.
As shown in Figure 1, being the structural schematic diagram of traditional Reynolds experiment device, when operating, passes through and adjust plastic spiral
The open degree of regulating valve changes the color water flow for entering needle tubing, flow velocity etc.；The open degree of plastic spiral regulating valve is to pass through rotation
Turn change, wherein the position of black O-ring be difficult control, failure it is more；It is changed into clear when blocking there is a situation where needle tubing
Water is poured into from above, positive pressure wash dredging；Or detaching equipment element, taking-up needle tubing rinse dredging, operation is extremely inconvenient.
And two-stage regulating device of the invention is when adjusting, fixed first order adjusting control valve, that is, plastic spiral regulating valve is opened
Qi Du, generally standard-sized sheet make its lumen become larger or become smaller to adjust by the regulating wheel extruding liquid pipe on sliding infusion regulator 2
Flow velocity.
After needle tubing is blocked, when maintenance, the open degree of fixed plastics adjustable diameter and screw adjusting valve 3, generally standard-sized sheet pass through sliding
Regulating wheel on infusion regulator 2 squeezes liquid pipe, its intraluminal pressure is made to become larger or become smaller, so that occurring in blocking needle tubing
Positive pressure or negative pressure dredge syringe needle.
Specific embodiments of the present invention are described above.It is to be appreciated that the invention is not limited to above-mentioned
Particular implementation, those skilled in the art can make a variety of changes or modify within the scope of the claims, this not shadow
Ring substantive content of the invention.In the absence of conflict, the feature in embodiments herein and embodiment can any phase
Mutually combination.
