Abstract

The utility model relates to the technical field of flow meters, particularly to a detector for detecting a gas flow meter with a bell jar type device serving as a standard device. The detector for detecting the gas flow meter with the bell jar type device serving as the standard device comprises a bell jar, a distribution box and a detected meter. The detector is characterized in that a travel disc is arranged on a support of the bell jar and sleeved with a travel pipeline; one end of the travel pipeline is connected with a weight, and the other end of the travel pipeline is connected with a liquid tank; a pressure outlet is arranged on the liquid tank and provided with a plurality of ports; one end of the pressure outlet of the liquid tank is connected with one end of a fluid pipeline of the detected meter through an air pipeline, and the other end of the pressure outlet of the liquid tank is connected with a meter pressure transmitter on the detected meter through the air pipeline. Compared with the prior art, the detector has the advantages that a micro-positive-pressure standard gas flow device is adopted, the operation is simple, in addition, by the aid of conversion of pressure compensation, the precision of correction results is high, and the quality of products is guaranteed.

Description

A kind ofly using bell-jar device and as standard, detect the pick-up unit of gas meter
Technical field
The utility model relates to flowmeter technology field, specifically a kind ofly usings bell-jar device and as standard, detects the pick-up unit of gas meter.
Background technology
Tradition is very complicated, loaded down with trivial details for the work of various gas meter table inspections, and need different detection parts to carry out its detection, expend a large amount of manpower and materials, because artificial detection unavoidably can be because work fatigue is neglected a certain procedure wherein, be easy to make underproof product to come into the market, cause certain potential safety hazard.
Summary of the invention
The utility model is for overcoming the deficiencies in the prior art, adopts the gas flow standard device of pressure-fired, simple to operate, and through pressure compensated conversion, and the precision that makes to proofread and correct result is high, guarantees the quality of product.
For achieving the above object, design a kind of pick-up unit of bell-jar device as standard detection gas meter of usining, comprise bell jar, panel box, tested table, it is characterized in that: the support of bell jar is provided with stroke disk, on stroke disk, be arranged with stroke pipeline, one end of stroke pipeline connects weight counterweight, and the other end of stroke pipeline connects liquid bath; Described liquid bath is provided with pressure export, and pressure export is provided with some ports, one end of the pressure export of liquid bath connects one end of the fluid circuit of tested table by air pipe line, the other end of the pressure export of liquid bath connects the gauge pressure transmitter on tested table by air pipe line.
The front end of described stroke disk is provided with pressure compensation mechanism.
Described stroke disk and the stroke pipeline between liquid bath are provided with scrambler.
The power supply place of described bell jar connects panel box.
The utility model compared with the existing technology, adopts the gas flow standard device of pressure-fired, simple to operate, and through pressure compensated conversion, and the precision that makes to proofread and correct result is high, guarantees the quality of product.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Referring to Fig. 1,1 is, 2 is stroke disk, and 3 is scrambler, and 4 is pressure compensation mechanism, and 5 is liquid bath, and 6 is gauge pressure transmitter, and 7 is absolute pressure transmitter, and 8 is fluid circuit, and 9 is tested table, and 10 is weight counterweight, and 11 is stroke pipeline.
Embodiment
With reference to the accompanying drawings the utility model is described further below.
As shown in Figure 1, the support of bell jar is provided with stroke disk 2, is arranged with stroke pipeline 11 on stroke disk 2, and one end of stroke pipeline 11 connects weight counterweight 10, and the other end of stroke pipeline 11 connects liquid bath 5; Described liquid bath 5 is provided with pressure export, and pressure export is provided with some ports, one end of the pressure export of liquid bath 5 connects one end of the fluid circuit 8 of tested table 9 by air pipe line, the other end of the pressure export of liquid bath 5 connects the gauge pressure transmitter 6 on tested table 9 by air pipe line.
The front end of stroke disk 2 is provided with pressure compensation mechanism 4.
Stroke pipeline 11 between stroke disk 2 and liquid bath 5 is provided with scrambler 3.
The power supply place of bell jar connects panel box 1.
By movable bell jar and fixing liquid bath 5, form the sealed cavity of a variable volume.In bell jar decline process, by pressure compensation mechanism 4, make its internal gas pressure keep certain value, the degree of depth not immersing in seal fluid with bell jar changes.Volume between bell jar two baffle plates is fixed, and measures the time that two baffle plates successively experience by photoelectric signaling device, can calculate instantaneous delivery, is directly presented on tested table 9, the quality of tested table 9 detected fast, intuitively.
