An Intelligent Piston Pressure Gauge Automatic Loading Structure

Abstract

The invention relates to an intelligent piston-type pressure gauge automatic loading structure. A base, a self-rotating piston assembly, an upper bearing beam, two bearing beam connection rods, a lower bearing beam, a thrust bearing, a T-shaped weight supporting rod, at least one cylinder driving-type double-hook weight suspension device, a ring-shaped weight, two fixing board supporting rods, two limiting rollers, two limiting roller supports, a cylinder fixing board, and a solenoid directional valve are connected to form the structure. The intelligent piston-type pressure gauge automatic loading structure has the beneficial effects that the upper bearing beam at the upper end of the piston of the self-rotating piston assembly and the lower bearing beam at the lower end are cable of bearing, the force bearing gravity of the piston is below the piston, force bearing is uniform, sensitivity is high, bearing is accurate, and the problems that the required number of tiny mass weights is large and the mass is small can be solved.

Description

technical field [0001] The invention relates to an intelligent piston pressure gauge for pressure detection, in particular to an automatic loading structure of the intelligent piston pressure gauge. Background technique [0002] At present, domestic high-precision intelligent piston pressure gauges can generally only be used for integer value pressure calibration, and the gravity acceleration, air density, piston deformation, temperature and other factors of the place of use have been corrected when the weight is balanced. The counterweight must be used under specific temperature and environmental conditions. A fully automatic pressure gauge verification device with the patent number CN02284501.1 realizes automatic correction of factors such as the acceleration of gravity, air density, piston deformation, and temperature. But because the weight bearing rod is long, the weight is located above the piston, and the load-bearing center of gravity is high, the sensitivity of the ...

Problems solved by technology

[0002] At present, domestic high-precision intelligent piston pressure gauges can generally only be used for integer value pressure calibration, and the gravity acceleration, air density, piston deformation, temperature and other factors of the place of use have been corrected when the weight is balanced. The counterweight must be used under specific temperature and environmental conditions. A fully automatic pressure gauge verification device with the patent number CN02284501.1 realizes automatic correction of factors such as the acceleration of gravity, air density, piston deformation, and temperature. But because the weight bearing rod is long, the weight is located above the piston, and the load-bearing center of gravity is high, the sensitivity of the piston is limited. The addition and subtraction of the correction weight is realized through the patent No. CN02284499.6 weight correction compensation mechanism. Due to the mechanism and The quality requirements are limited, the number and the minimum weight quality are limited, so the uncertainty can only reach 0.01%
