Abstract
The utility model relates to a meter to test the liquid pressure. The utility model comprises a steady plate, a scale plate fixed on the steady plate, a U shape pipe fixed on the scale plate and a pressure box connected with the U shape pipe; the U shape pipe is connected with the upper end of the supporting pipe through the soft pipe; the lower end of the supporting pipe is connected with the pressure box; the pressure box is connected with the U shape pipe through the steel supporting pipe to avoid the influence of the deformation of the soft pipe to the testing precision; the steel supporting pole is provided with scale to read the depth of the pressure box; and the adjusting handle can adjust the direction of the pressure box through the pulling rope. Therefore the utility model is convenient to be used and has an accurate positioning.
Description
Technical field
The utility model relates to a kind of instrument of measuring liquid pressure.
Background technology
An experiment of measuring the pressure of different depth liquid is arranged in middle and primary schools' Physical Experiment Course, the piezometer that uses comprises the scaleplate that is fixed on the base plate, have " U " shape glass tube on the scaleplate, liquid is arranged in the glass tube, with glass tube and a pressure cell soft pipe connection.Like this, when pressure cell being placed in the liquid of different depth, just can on scaleplate, read pressure and pressure.There is following deficiency in this piezometer: 1) can not directly read the liquid depth of pressure cell present position from pressure gauge, use cumbersome, if measure the precision also can influence measurement with ruler.Will inevitably immerse liquid by some flexible pipe, the accuracy that influence is measured when 2) pressure cell is put into liquid.3) end of " U " shape pipe has one and ends the gas folder, when the two ends of " U " shape pipe liquid level keeps balance, has equal pressure, folder on only gas press from both sides and just can record pressure values accurately.But because rubber hose unavoidably will produce distortion when folder ends the gas folder, make the two ends pressure of " U " shape pipe different big, produce experimental error.Be difficult to guarantee that the degree of depth of pressure cell is constant when 4) the rotational pressure box is measured the pressure of different directions; On the other hand, also make flexible pipe produce torsional deformation during the rotational pressure box easily, water discharge changes, the accuracy that influence is measured.
Summary of the invention
The purpose of this utility model provides a kind of easy to use, Manometer that measuring accuracy is high.
For achieving the above object, the utility model adopts following technical scheme:
Manometer described in the utility model comprises steadying plate, be fixed on scaleplate on the steadying plate, be fixed on " U " shape pipe on the scaleplate, manage the pressure cell that is communicated with " U " shape, it is characterized in that: " U " shape pipe is communicated with the upper end of stay pipe by flexible pipe, and the lower end of stay pipe is communicated with pressure cell.
As to further improvement of the utility model, can also have the runner that is connected in one with pressure cell in the junction of pressure cell and stay pipe lower end, one end of drag-line is wrapped on the runner, the other end is wrapped on the adjusting handle, and adjusting handle is fixed on the upper end of stay pipe by the clamped-in style support.
After adopting technique scheme, the stay pipe by rigidity between pressure cell and " U " shape pipe is connected, and has avoided the influence of the torsional deformation of flexible pipe to measuring accuracy, can also engrave scale on the support bar of rigidity, can directly read the degree of depth of pressure cell; The direction that adjusting handle is regulated pressure cell by drag-line, easy to use, accurate positioning.
Description of drawings
Accompanying drawing is the structural representation of an embodiment of the present utility model.
Embodiment
As shown in drawings, Manometer described in the utility model comprises steadying plate 1 as base plate, be fixed on scaleplate 2 on the steadying plate 1, be fixed on " U " shape pipe 3 on the scaleplate 2, " U " shape pipe 3 is communicated with the upper end of stay pipe 6 by flexible pipe 5, and the lower end of stay pipe 6 is communicated with pressure cell 4.Stay pipe 6 can be selected corrosion resistant metal tube for use, engraves the scale of the expression degree of depth at its outer wall.The lower end of stay pipe 6 is square elbows, and this square elbow is connected with the interface of pressure cell 4.Interface at pressure cell 4 has the runner 7 that is connected in one with pressure cell 4, and an end of drag-line 8 is wrapped on the runner 7, and the other end is wrapped on the adjusting handle 9, and adjusting handle 9 is fixed on the upper end of stay pipe 6 by clamped-in style support 10.
In addition, " U " shape pipe 3 ends that communicate with atmosphere can also be provided with two sharp mouths that opening is less, one of them is connected with stay pipe 6 by flexible pipe, and another replaces ending the gas clamp with rubber cap and closes " U " shape pipe 3, can avoid the error that produces when only gas presss from both sides grip both hose.
When pressure cell is put into water, can directly read the degree of depth from support bar 6, the direction that the rotation adjusting handle just can be regulated pressure cell, easy to use, the accuracy height of measurement.
