Abstract
The utility model discloses a U-shaped tube differential gauge which is convenient to measure and read and can reduce reading frequency, shorten reading time and improve measuring accuracy. The U-shaped tube differential gauge comprises a U-shaped tube, wherein the U-shaped tube is fixed on a back panel; the back panel is provided with at least one graduated scale which moves along the height of a liquid column; a graduation line 0 of the graduated scale is aligned with the bottom end of the liquid column during measurement; and the graduation line of the graduated scale aligned with the top end of the liquid column is the tested pressure.
Description
Technical field
The utility model relates to a kind of plurality of fluid pressure gauges, relates in particular to a kind of U-shaped pipe differential pressure gauge.
Background technology
In fields such as scientific research, production, usually to use the pressure that U-shaped pipe differential pressure gauge is measured fluid.U-shaped pipe differential pressure gauge is simple and reliable because of it, has obtained using widely.The U-shaped pipe differential pressure gauge that is adopted at present is as shown in Figure 1, is fixed on the glass tube of a U-shaped on the backboard, and fixing simultaneously rule has just been formed U-shaped pipe differential pressure gauge.
U-shaped pipe differential pressure gauge institute measuring pressure is high more, and the liquid-column height difference of both sides is big more, and the scale that deducts opposite side with the scale of a side during reading just obtains tested force value.When pressure changed, the height of U-shaped pipe differential pressure gauge both sides fluid column changed simultaneously, and a side raises, and a side descends, and this is that the structure of U-shaped pipe differential pressure gauge determines.Therefore, when reading the differential pressure value of U-shaped pipe differential pressure gauge measurement, read the liquid-column height of both sides, the liquid-column height value of both sides added and subtracted just can be obtained measured differential pressure value.The survey differential pressure value is big or institute's measuring pressure constantly changes, when fluctuating, all more loaded down with trivial details to U-shaped pipe differential pressure gauge accurate reading, strengthened the number of times of reading and calculating, increased and measured the required time, also cause the error of measurement easily.
The utility model content
The purpose of the utility model provides a kind of measurement, easy-to-read U-shaped pipe differential pressure gauge be convenient to exactly for addressing the above problem, and can reduce the reading number of times, shortens the reading duration, improves accuracy of measurement.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of U-shaped pipe differential pressure gauge; It comprises the U-shaped pipe, and the U-shaped pipe is fixed on the backboard, and said backboard is provided with at least one rule that moves along the liquid-column height direction; 0 scale mark of rule is aimed at the fluid column bottom when measuring, and the rule scale of being aimed at by the fluid column top is institute's measuring pressure.
Said backboard is provided with slide rail, and rule is installed on the slide rail.
Said backboard is provided with groove, and rule slides and is inlaid in the groove.
The utility model is installed a rule that can move along the liquid-column height direction on existing U-shaped pipe differential pressure gauge, during measurement, move this rule, makes its 0 scale aim at the bottom of fluid column, reads the scale on fluid column top, just can obtain the pressure of being surveyed.Owing to only need read scale one time, just can obtain institute's measuring pressure, improved efficiency of measurement and accuracy of measurement.As required, also a more than transportable rule can be installed on U-shaped pipe differential pressure gauge, use with convenient.
The beneficial effect of the utility model is: simple in structure, easy to use, cost is lower, and the accuracy of measurement obviously improves.
Description of drawings
Fig. 1 is existing U-shaped pipe differential pressure gauge synoptic diagram.
Fig. 2 is the structural drawing of the utility model U-shaped pipe differential pressure gauge user mode one.
Fig. 3 is the structural drawing of the utility model U-shaped pipe differential pressure gauge user mode two.
Wherein, 1.U shape pipe, 2. backboard, 3. rule.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Among Fig. 2, Fig. 3, it comprises backboard 2, and U-shaped pipe 1 is fixedly mounted on the backboard 2.Be provided with the rule 3 that moves with respect to backboard 2 in backboard 2 upper edge liquid-column height directions, the connected mode that rule 3 and backboard are 2 has multiple, and for example: on backboard 2, be provided with slide rail, rule 3 is installed on the slide rail; Perhaps, backboard 2 is provided with groove, and rule 3 slides and is inlaid in the groove.Certainly also can adopt other variety of ways, but as long as guarantee that rule 3 can slide on backboard 2.
During measurement, move this rule, make its 0 scale aim at the bottom of fluid column, read the scale on fluid column top, just can obtain the pressure of being surveyed.Owing to only need read scale one time, just can obtain institute's measuring pressure, improved efficiency of measurement and accuracy of measurement.
