Abstract

The invention discloses a verification system of a pressure measuring instrument. The verification system comprises a measured pressure meter, a standard meter, a working liquid pipeline, a working piston, a weight, a weight piston and a propelling hand wheel system. The measured pressure meter and the standard meter are arranged on branch path pipelines of the working liquid pipeline, the working piston is arranged at one end of the working liquid pipeline, the weight piston is arranged at the other end of the working liquid pipeline, the weight is arranged on the weight piston, and the propelling hand wheel system is arranged at the end of the working piston. The verification system is simple in structure, precise in measuring and long in service life. The weight is a metering instrument, due to the fact that the mass of the weight is known, the pressure magnitude of a measured medium can be known through reading of the weight, and the standard meter is used as reference contrast.

Description

A kind of pressure instrumentation verification system
Technical field
The present invention relates to survey instrument field, particularly relate to a kind of pressure instrumentation verification system.
Background technology
In Chemical Manufacture, pressure is a very important parameter, and it affects efficiency and the progress of whole reaction.The method of existing measurement pressure is all arrange tensimeter on tested pipeline, and the object measured is wished by measuring the actual value obtaining measured parameter, but due to a variety of causes, the harmful effect etc. of as perfect not to the utmost in measuring method, pick-up unit defect, environmental factor and human factor, cause the measured value of measured parameter and actual value and inconsistent, between them, always there is certain error.Then design and be a kind ofly used for measuring pressure and the technical tool that can obtain measurand exact value seems particularly important.
Summary of the invention
The present invention, in order to overcome the deficiency of above-mentioned technical matters, provides a kind of pressure instrumentation verification system, can solve the problems of the technologies described above completely.
The technical scheme solved the problems of the technologies described above is as follows:
A kind of pressure instrumentation verification system, comprise tested tensimeter, standard scale, working liquid pipe, working piston, counterweight, counterweight piston and advance hand wheel system, described tested tensimeter and standard scale are arranged in the bypass line of working liquid pipe, one end of described working liquid pipe arranges working piston, the other end arranges counterweight piston, described counterweight upper piston area is provided with counterweight, and the end of described working piston is provided with propelling hand wheel system.
Structure of the present invention is simple, measures precisely, long service life.Counterweight in the present invention is a kind of measurement instrument, and the quality due to counterweight is known, therefore can know the pressure size of measured medium according to the reading of counterweight, standard scale be intended for reference to contrast.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention;
Embodiment
A kind of pressure instrumentation verification system as shown in Figure 1, comprise tested tensimeter 1, standard scale 2, working liquid pipe 3, working piston 4, counterweight 7, counterweight piston 6 and advance hand wheel system 5, described tested tensimeter 1 and standard scale 2 are arranged in the bypass line of working liquid pipe 3, one end of described working liquid pipe 3 arranges working piston 4, the other end arranges counterweight piston 6, described counterweight piston 6 top is provided with counterweight 7, and the end of described working piston 4 is provided with and advances hand wheel system 5.
Structure of the present invention is simple, measures precisely, long service life.Counterweight in the present invention is a kind of measurement instrument, and the quality due to counterweight is known, therefore can know the pressure size of measured medium according to the reading of counterweight, standard scale be intended for reference to contrast.
