Description
Technical field
The present invention relates to measuring instrument and fields of measurement, more particularly, to a kind of aperture wind field Flow speed measurer.
Background technology
It is frequently necessary in scientific research and engineering construction impact point or region are carried out tachometric survey, but owing in the smaller range at aperture, gas velocity gradient is big, and flowing is possible and unstable at single aperture, fluctuating within the specific limits, what accurate stable all had no idea by the most most of anemobiagraphs measures the speed of gas at aperture.Directly using common anemobiagraph to measure the numerical value obtained and may differ relatively big with actual value, or reading can not well be stablized when measuring, this all makes measured value not use.
Summary of the invention
The present invention is to overcome at least one defect (not enough) described in above-mentioned prior art, it is provided that a kind of aperture wind field Flow speed measurer.
For solving above-mentioned technical problem, technical scheme is as follows:
A kind of aperture wind field Flow speed measurer, including base, barretter and measurement chip, described barretter be arranged on base top and with base UNICOM, described measurement chip is arranged in barretter；Described base is used for guiding air-flow, described measurement chip to be used for measuring air-flow.
Further as optimal technical scheme, also include that pressure-measuring pipe, the dismountable connection of described pressure-measuring pipe are connected to the other end of barretter.
Further as optimal technical scheme, also including that packing ring, described packing ring are arranged on base bottom, described packing ring is fabricated from a flexible material.
Further as optimal technical scheme, described packing ring is vacuum packing ring.
Further as optimal technical scheme, also including display screen, described display screen is connected for showing measurement result with measuring chip.
Further as optimal technical scheme, it is smooth contracted section between top cross-section area, and the bottom of base and top that the bottom section area of described base is more than.
Further as optimal technical scheme, removably connect between described barretter and base.
Further as optimal technical scheme, it is connected by screw thread facing between described barretter and base.
Compared with prior art, technical solution of the present invention provides the benefit that:
The impact of flowing instability is decreased so that more stable accurately to the tachometric survey reading at aperture by the measurement that porous is average.The design of base makes measurement more convenient.

Accompanying drawing being merely cited for property explanation, it is impossible to be interpreted as the restriction to this patent；In order to the present embodiment is more preferably described, some parts of accompanying drawing have omission, zoom in or out, and do not represent the size of actual product；To those skilled in the art, in accompanying drawing, some known features and explanation thereof may will be understood by omission；The corresponding same or analogous parts of same or analogous label；Term the being merely cited for property explanation of position relationship described in accompanying drawing, it is impossible to be interpreted as the restriction to this patent.
Detailed description of the invention
With embodiment, technical scheme is described further below in conjunction with the accompanying drawings.
Embodiment 1
A kind of aperture wind field Flow speed measurer, including base 1, barretter 2, measures chip 3, packing ring 4 and display screen 5, described barretter 2 be arranged on base 1 top and with base 1 UNICOM, removably connected by screw thread facing between barretter 2 and base 1；Described measurement chip 3 is arranged in barretter 2；Described base 1 is used for guiding air-flow, described measurement chip to be used for measuring air-flow；Display screen 5 is connected for showing measurement result with measuring chip 3.
Packing ring 4 is arranged on bottom base 1, and packing ring 4 is fabricated from a flexible material, and the present embodiment is preferably vacuum packing ring.
It is smooth contracted section between top cross-section area, and the bottom of base 1 and top that the bottom section area of base 1 is more than.
Using method: collected the gas flowing through single or multiple aperture during use by base, when gas flows through barretter, flowing tends to be steady, thus use in barretter stage casing and measure the chip stable flow velocity of measurement, obtain the most multiple aperture mean flow raties by area ratio conversion.Further, base uses vacuum packing ring in use, instrument can be made to be adsorbed in measuring surface, not only ensure that sealing but also can be convenient for measuring measuring surface is not plane when.And base dimensions can be determined according to the little hole count of actually required measurement and aperture distributed dimension, choose the base of respective model.Simultaneously because measure chip have the measurement upper limit, minimum diameter needed for barretter can be determined according to estimating velocity interval at aperture, in guaranteeing barretter, gas velocity is in Active Area, choose suitable barretter model, if reading is less than normal, it is considered to increase and measure little hole count or choose the barretter that internal diameter is less, if reading exceedes range, can consider to reduce and measure little hole count or choose the barretter that internal diameter is bigger, by screw thread facing method, the base chosen is installed and barretter measures.In use base use smooth contracted section design make air-flow through time local energy loss less.
Use example: measure a working face horizontal porous working face as shown in Figure 3.Hole diameter 1mm, pitch of holes 2mm.According to the estimated data of gas velocity at the aperture of plate face, choose 4 apertures of measurement, the corresponding base using diameter 47mm and the barretter of internal diameter 6mm.Open air pump, start after a period of time to measure, measure scope as shown in Figure 4.Through twice duplicate measurements to measured zone, two secondary data are the most identical, measure and have repeatability.Can find, use aperture Flow speed measurer that reading can be made more stable accurately.
Embodiment 2
The present embodiment is similar to embodiment 1, as shown in Figure 4, also includes that pressure-measuring pipe 6, the dismountable connection of described pressure-measuring pipe are connected to the other end of barretter.
During use, the when of measuring aperture pressure, pressure-measuring pipe 6 is connected to barretter, by reading at aperture and the difference of atmospheric pressure, to obtain force value at aperture further.
Obviously, the above embodiment of the present invention is only for clearly demonstrating example of the present invention, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here without also cannot all of embodiment be given exhaustive.All any amendment, equivalent and improvement etc. made within the spirit and principles in the present invention, within should be included in the protection domain of the claims in the present invention.
