Problems solved by technology

[0009] In order to solve the problem that it is difficult to replace the elastic ball in the existing two-way volume tube, the present invention provides a solution for storing a spare elastic ball in the volume tube, and the spare elastic ball can be used without opening the volume tube quick-opening blind plate. Ball for flowmeter verification to verify elastic ball damage

Abstract

The invention provides a built-in standby ball system of a bidirectional volume tube, comprising a volume tube provided with a quick-open blind plate, a device which comprises a spring telescopic mandrill and prevents a ball from falling, and a ball launching device. The volume tube is internally and additionally provided with a standby ball which can enter into a ball storage chamber under the pushing of verification liquid; the connection tube of the quick-open blind plate and the volume tube is provided with the ball storage chamber, so that the replacement of the running ball without stopping and emptying the volume tube can be easily realized. The invention can conveniently detect whether the original running ball loses effectiveness by a mode of comparing the two balls, and has high running efficiency of the volume tube as well as simple and convenient operation of ball replacement.

Description

Technical field [0001] The invention relates to a two-way standard volume tube used for calibrating flow meters. In a specially processed and coated tube section determined by volume, an elastic ball called a displacer is placed. The elastic ball can move freely in the tube section. But it must form a sliding seal with the inner wall of the tube, and its moving speed in the tube is exactly the same as the speed of the liquid flowing through the tube, which can be used to calibrate the flowmeter. Background technique [0002] The accuracy of the flowmeter is the most important index among the characteristics of the flowmeter. The so-called calibration of the flowmeter is to compare it with the indication value of the standard measuring instrument with higher accuracy, and it is generally expressed by the error percentage corresponding to the maximum value of the flowmeter. The calibration of the flowmeter was first based on the mass method, that is, the mass of the liquid pa...
