Abstract
It is connected the utility model discloses a kind of from below exhaust direct-reading multipoint pressure measure pipe, including top water tank, pressure-measuring pipe and hose, the top water tank with several pressure-measuring pipes, pressure-measuring pipe is connected by hose with model pipeline, and the pressure-measuring pipe is equipped with scale.Certainly the exhaust direct-reading multipoint pressure measure pipe of the utility model, the water in the water tank of top can be controlled to be carried out to pressure-measuring pipe from exhaust by inlet valve, the water surface reading of each pressure-measuring pipe can be quickly and easily read according to the pressure-measuring pipe of differentiation scale, and then piezometric head is determined by datum level, and the when dynamic hydraulic pressure for extrapolating according to measuring point elevation each measuring point is strong.And multiple measuring points can be measured at the same time, including horizontal, longitudinal or each diverse location, easily operated, accuracy is high, and practicality is extremely strong.
Description
Technical field
It the utility model is related to from exhaust direct-reading multipoint pressure measure pipe, belong to hydraulic model test field.
Background technology
In hydraulic model test, often refer to then move the strong measurement of hydraulic pressure, at present the measurement dress on hydraulic model
Put and utilize law of connected vessels, generally using hose, connect at required measurement pressure, then secure the hose to somewhere,
Treat to carry out reading after stable level, calculate to obtain thus according to corresponding relation to take and move hydraulic pressure intensity values.With regard to current
For device, there are some shortcomings, hose itself material problem and caliber is meticulous be easy to cause water under the action of surface tension
Easily form partition bubble so that measurement result is inaccurate, the influence that bubble produces in order to prevent, in use, needing to take height
The method of pressure injection water is exhausted, so cumbersome and time consuming, simultaneously because hose, yielding, in reading, precision is opposite
Also it is poor.
Utility model content
Purpose of utility model：In order to overcome the deficiencies in the prior art, the utility model provides a kind of straight from being vented
Reading formula multipoint pressure measure pipe, can directly read data from being vented, while can measure multiple spot, including horizontal, longitudinal or each
The pressure-measuring pipe of diverse location is necessary, and during experiment, not only test data is more accurate reliable, and greatlys save
Time and human cost.
Technical solution：In order to solve the above technical problems, the utility model is a kind of from exhaust direct-reading multipoint pressure measure pipe, bag
Top water tank, pressure-measuring pipe and hose are included, is connected below the top water tank with several pressure-measuring pipes, pressure-measuring pipe passes through hose and mould
Type pipeline connects, and the pressure-measuring pipe is equipped with scale.
Preferably, the top water tank is equipped with water inlet pipe.
Preferably, the top water tank is installed on rigid frame, pressure-measuring pipe is fixed on the water tank of top.
Preferably, the pressure-measuring pipe is connected by ozzle made of pmma material with hose.
Beneficial effect：Certainly the exhaust direct-reading multipoint pressure measure pipe of the utility model, can control top water by inlet valve
Water in case carries out pressure-measuring pipe, from being vented, the water of each pressure-measuring pipe can be quickly and easily read according to the pressure-measuring pipe of differentiation scale
Face reading, and then piezometric head is determined by datum level, and the when dynamic hydraulic pressure for extrapolating according to measuring point elevation each measuring point is strong.
And multiple measuring points can be measured at the same time, including horizontal, longitudinal or each diverse location.The present invention can be tried in hydraulic model
Middle use is tested, easily operated, accuracy is high, and practicality is extremely strong.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Embodiment
As shown in Figure 1, the utility model is a kind of from exhaust direct-reading multipoint pressure measure pipe, including top water tank 1, inlet valve
2nd, pressure-measuring pipe 3, pressure measurement ozzle 4, hose 5 and rigid frame 6.At the trial, inlet valve 2 is opened, injects one in top water tank 1
Quantitative water, open inlet valve 2, to pressure-measuring pipe carry out water filling exhaust, after close inlet valve 2.It is easy to operate, greatly save
Time and human cost.
The pressure-measuring pipe 3 is made of pmma material, bore 1cm.3 upper end of pressure-measuring pipe connects with top water tank 1
Connect, the lower end of pressure-measuring pipe 3 is connected by pressure measurement ozzle 4 and hose 5 with model pressure measuring point.Break up mm scales on pressure-measuring pipe 3, it is full
Sufficient routine test needs.The pressure measurement ozzle 4 is made of pmma material, and pressure-measuring pipe 3 and hose 5 are connected.It is soft
Pipe 5 is by pressure-measuring pipe 3 with being connected at model pressure measuring point.The rigid frame 6 plays top water tank 1, the fixation of the grade of pressure-measuring pipe 2
Come, for ensureing that device is stablized.
The implementation process of the present invention is as follows：At the trial, inlet valve 2 is opened, is injected by water inlet pipe in top water tank 1
A certain amount of water, open inlet valve 2, to pressure-measuring pipe carry out water filling exhaust, after close inlet valve 2.Treat that model water level is stablized
Afterwards, the water surface reading of each pressure-measuring pipe 3 can quickly and easily be read according to the pressure-measuring pipe 3 of differentiation scale, and then passes through datum level
Determine piezometric head, and the when dynamic hydraulic pressure for extrapolating according to measuring point elevation each measuring point is strong.Whole implementation process is easy to operate,
Data accuracy is high, and practicality is extremely strong.
The above is only the preferred embodiment of the utility model, it should be pointed out that：For the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
