Carry out the dismounting of pressure gauge.It being capable of on-line checking pressure meter device for this purpose, being badly in need of one kind.
Therefore, how to provide it is a kind of can on-line checking pressure meter device be asking for those skilled in the art's urgent need to resolve
Topic.
Utility model content
In view of this, the utility model provides a kind of pressure gauge on-line measuring device, improves work efficiency, reduce
Goods and materials are lost, and the device is easy to operate, and production scene is suitble to use.
To achieve the goals above, the utility model adopts the following technical solution:
A kind of pressure gauge on-line measuring device, including:Pressure generator, master gauge, the first shut-off valve, tested pressure
Table, the second shut-off valve and main line;
The pressure generator is sequentially connected the first shut-off valve, the second shut-off valve and main line;Wherein, the pressure occurs
It is connected with the master gauge between device and first shut-off valve;Between first shut-off valve and second shut-off valve
It is connected with the tested pressure gauge.
Preferably, the master gauge by triple valve access the pressure generator and first shut-off valve it
Between.
Preferably, the tested pressure gauge by triple valve access first shut-off valve and second shut-off valve it
Between.
It can be seen via above technical scheme that compared with prior art, the utility model, which discloses, provides a kind of pressure gauge
On-line measuring device can examine and determine online or spare pressure gauge, save measuring cost, alleviate the labor of operator
Fatigue resistance improves work efficiency, and reduces goods and materials loss, and the device is easy to operate, of low cost, is relatively suitble to production
Onsite application.
Description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment

Referring to attached drawing 1, the utility model embodiment discloses a kind of pressure gauge on-line measuring device, including:Pressure occurs
Device 1, master gauge 2, the first shut-off valve 3, tested pressure gauge 4, the second shut-off valve 5 and main line 6;
Pressure generator 1 is sequentially connected the first shut-off valve 3, the second shut-off valve 5 and main line 6;Wherein, pressure generator 1
And first be connected with master gauge 2 between shut-off valve 3;It is connected with tested pressure between first shut-off valve 3 and the second shut-off valve 5
Table 4.
Online or spare pressure gauge can be examined by pressure gauge on-line measuring device provided by the utility model
It is fixed, measuring cost has been saved, the labor intensity of operator has been alleviated, improves work efficiency, has reduced goods and materials loss, and should
Device is easy to operate, of low cost, relatively production scene is suitble to use.
Above-mentioned technical proposal is advanced optimized, master gauge 2 is ended by triple valve cut-in pressure generator 1 and first
Between valve 3.
Above-mentioned technical proposal is advanced optimized, pressure gauge 4 is detected and the cut-off of first shut-off valve 3 and second is accessed by triple valve
Between valve 5.
The detection device of pressure gauge provided by the utility model only needs slightly modified on the basis of former pipeline.Mark
Quasi- pressure gauge and tested pressure gauge are accessed by triple valve in pipeline, and access between master gauge and tested pressure gauge the
One shut-off valve accesses the second shut-off valve tested between pressure gauge and main line.
The detecting step of pressure gauge on-line measuring device provided by the utility model is described below.
When detection, the second shut-off valve is closed, cuts off the connection between main line and tested pressure gauge, opens the first cut-off
Valve, cut-in pressure generator, master gauge and tested pressure gauge.
Pressure gauge calibrating is carried out according to JJG52 vertification regulations, and records related data;
After calibrating, the first shut-off valve is closed, the tested connection between pressure gauge and pressure generator of cut-out opens the
Two shut-off valves are connected to and are detected pressure gauge and main line.
Each embodiment is described by the way of progressive in this specification, the highlights of each of the examples are with other
The difference of embodiment, just to refer each other for identical similar portion between each embodiment.For device disclosed in embodiment
For, since it is corresponded to the methods disclosed in the examples, so description is fairly simple, related place is said referring to method part
