Detailed Description
The utility model provides a portable U type pressure gauge of complex environment wide range. In order to make the objects, technical solutions and effects of the present invention clearer and clearer, the following description of the present invention will refer to the accompanying drawings and illustrate embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
The utility model provides a large-range portable U-shaped pressure gauge in complex environment, which comprises an adjustable base 70, a fixed shell 20, a double-sided graduated scale 30, a damping valve 60, a communicating pipe 50 with a balance valve, a first U-shaped pipe 10 and a second U-shaped pipe 11; the medium can be selected from tap water and the like, and the utility model is not limited; fixing the first U-shaped pipe 10, the second U-shaped pipe 11 and the double-sided graduated scale 30 by using the fixed shell 20; the level 40 is disposed at the bottom of the stationary housing 20.
The adjustable base 70 is used for adjusting the fixed shell 20, the observation level gauge 40 enables the liquid column to be in the middle position, and the first U-shaped pipe 10, the second U-shaped pipe 11, the double-faced graduated scale 30 and the like are guaranteed to be in the vertical direction integrally. The adjustable base 70 is adjusted by adjusting the height of the 4 adjustable legs 80.
The communicating pipe 50 with the balance valve is connected with the first U-shaped pipe 10 and the second U-shaped pipe 11, the balance valve is opened to communicate with the atmosphere during medium filling, so that the first U-shaped pipe 10 and the second U-shaped pipe 11 are continuously filled with the medium, the liquid level is filled to a certain height position of the double-sided scale 30 (for reading convenience, the scale position of 0 point is suggested), and then the balance valve is closed, so that the first U-shaped pipe 10 and the second U-shaped pipe 11 are in a sealed serial state.
During testing, the first U-shaped pipe 10 is connected to the pressure measuring end, and the damping valve 60 is installed on the side, connected with the atmosphere, of the second U-shaped pipe 11. The damper valve 60 is used to avoid situations where the equilibrium pressure fluctuations cause rapid fluctuations in the liquid level that cannot be read.
When reading, only the height difference h (mm) of the first U-shaped pipe 10 or the second U-shaped pipe is read, the corresponding pressure is g h (Pa), and the actual pressure is 2 times g h (g is 9.8 m/s) 2 ). Actual number of readingsDuring the value measurement, the height difference of the first U-shaped pipe 10 and the second U-shaped pipe 11 can be respectively read by two persons, and finally the average value of the readings of the first U-shaped pipe and the second U-shaped pipe is taken as a measurement result so as to reduce the final pressure deviation caused by visual errors and improve the measurement precision.
