Abstract
A pressure measurement device of fluid is prepared for forming tube by hard transparent material, setting piston in tube, making pressure scale on tube body, setting pressure-measurement and pressure-regulation interface connected to tested gas on end of said tube, setting calibration gas hole on another end of said tube and arranging sealed switch on said calibration gas hole.
Description
Affiliated technical field
The present invention relates to a kind of device that can measure fluid pressure.
Background technology
Pressure and vacuum measurement technology have widely in industries such as manufacturing, electronics, aviation, traffic, metallurgy, the energy, materials to be used, and can play the effect of technical support to industrial and development of science and technology.At present, known gas pressure intensity measuring principle has: one, fluid column relative height mensuration; Two, by pressure transducer pressure signal is converted to displacement signal or electric signal, combines measuring method with displacement, electric signal measurement Displaying Meter.Yet use the measurement mechanism volume of first kind of principle big, range is restricted; Adopt the measurement mechanism cost of second kind of principle higher, can not require directly use under nontoxic, the aseptic condition.More than two kinds of pressure measurers be difficult to all directly accomplish that volume is little, nontoxic aseptic, it is little not have a kind of volume in the market, broad quantum, to make use cost low, non-transformer, nontoxic, aseptic pressure measurer.
Summary of the invention
The invention provides a kind of pressure measurer, adopt under the temperature-resistant situation gas pressure intensity and the volume principle that is inversely proportional to, this installs not only broad quantum, it is low to make use cost, non-transformer, volume can be by measuring accuracy, range requirement design, and can be nontoxic, aseptic, can be in industrial or agricultural, medical industry widespread use.
The technical solution adopted for the present invention to solve the technical problems is: a kind of gas pressure intensity measurement mechanism, it is characterized in that: make by the hard transparent pipe, in piston is arranged, pipe shaft indicates the pressure scale, one end has the pressure measuring and regulating interface that communicates with tested gas, one end is provided with the calibration blow vent, on the calibration blow vent enclosed switch is arranged.The hard transparent pipe can be that a pipe is formed, and also can be made up of interior pipe and outer tube; Piston can be a solid, also can be liquid.
Description of drawings
Fig. 1, Fig. 2 are negative pressure measurement mechanism structural drawing, and Fig. 3 is positive pressure measuring device structural drawing.1, annular seal space, 2, pressure measuring cavity, 3, piston, 4, the pressure measuring and regulating interface, 5, the calibration blow vent, 6, enclosed switch, 7, scale.
The present invention is further described below in conjunction with accompanying drawing.
One, zeroing
Open enclosed switch, annular seal space is communicated with atmosphere, Fig. 1, Fig. 3 adopt the solid material piston, by pressure modulating opening regulating piston to 0 scale mark; Fig. 2 adopts liquid as piston, and inside and outside two chambeies are divided into annular seal space and pressure measuring cavity.By adding liquid, make liquid level to 0 scale mark; Close enclosed switch and make annular seal space and big flow of QI being obstructed.
Two, the pressure measurement interface is communicated with tested gas
Observe piston (interior pipe liquid level) and scale mark, both can read tested gas pressure intensity.
The invention has the beneficial effects as follows, this pressure measurer not only broad quantum, to make use cost low, non-transformer, volume can design by measuring accuracy, range requirements, can get rid of temperature disturbance.And can be nontoxic, aseptic, can especially be fit to gas pressure intensity and measure in industrial or agricultural, medical industry widespread use.
Claims (3)
1. fluid pressure measurer is characterized in that: make by the hard transparent pipe, in piston is arranged, pipe shaft indicates the pressure scale, an end has the pressure measuring and regulating interface that communicates with tested gas, an end is provided with the calibration blow vent, on the calibration blow vent enclosed switch is arranged.
2, the described hard transparent pipe of claim 1 is characterized in that: can be a pipe, also can be made up of interior pipe and outer tube.
