Description
Technical field
The utility model relates to motor valve detection devices, in particular relate to a kind of gas meter, flow meter built-in motor valve sealing propertytest
Device.
Background technique
It is mounted on the motor valve inside gas meter housing and is called built-in motor valve, many all includes in present domestic gas meter
There is built-in motor valve.Often built-in motor valve is detected when producing or repairing built-in motor valve, especially motor
The leakproofness of valve, so that it is determined that can it working properly.In the prior art, generally by the way of interim connecting detection system pair
Built-in motor valve leakproofness is detected, and more unprofessional detection device pays little attention to detection, so detecting
During built-in motor valve leakproofness, often will appear it is micro- leakage and be not easy the phenomenon that being found, occur manual operation inaccuracy and
The disadvantages of randomness is big.Finished gas table is caused to be easy to appear practical phenomena such as using gas and inconsistent metering.
Summary of the invention
Problem to be solved in the utility model is to propose a kind of gas meter, flow meter built-in motor valve device for detecting sealability, is improved
Gas meter, flow meter quantification stability makes automation degree of equipment and production efficiency increase, and prolongs the service life.
The utility model provides a kind of gas meter, flow meter built-in motor valve device for detecting sealability, it is characterised in that: is detected by 1#
Tooling 1,2# detecting tool 2, pneumatic thread straight-through connector 3 and leak detector 4 form, and connection relationship is: 1 side of 1# detecting tool
It is formed with a threaded hole 6, is installed on threaded hole 6 after unsintered tape 7 being wound at pneumatic 3 screw thread of thread straight-through connector；It will leak detection
Steam hose 8 on instrument 4 is connected to pneumatic thread straight-through connector 3；By built-in motor valve 5 with peace at the air inlet of 1#O type circle 9
Mounted in 1 top of 1# detecting tool, 2# detecting tool 2 is installed at gas outlet of the built-in motor valve 5 with 2#O type circle 10.
The beneficial effects of the utility model are: compared to the built-in motor valve detection system temporarily connected, the built-in motor
Valve device for detecting sealability can make detection process more codes and standards, not only convenient and efficient, and can exclude such as poor contact
Deng interference, keep testing result more accurate.
Detailed description of the invention
Fig. 1 the utility model structure diagram.
In figure: 1,1# detecting tool, 2,2# detecting tool, 3, pneumatic thread straight-through connector, 4, leak detector, 5, built-in motor
Valve, 6, threaded hole, 7, unsintered tape, 8, steam hose, 9,1#O type circle, 10,2#O type circle, 11, valve.
Specific embodiment
A specific embodiment of the invention is discussed in detail below in conjunction with attached drawing.
Embodiment 1: the utility model discloses a kind of gas meter, flow meter built-in motor valve device for detecting sealability, by 1# detecting tool
1,2# detecting tool 2, pneumatic thread straight-through connector 3 and leak detector 4(FL-295C FUKUDA company) composition.The 1# detects work
1 is filled for detecting 5 inner sealing of built-in motor valve；The 2# detecting tool 2 seals outside built-in motor valve 5 for detecting
Property；The pneumatic thread straight-through connector 3 is installed in 1# detecting tool 1；The leak detector 4 is connected to pneumatic thread straight-through connector
3。
The 1# detecting tool 1 and 2 material of 2# detecting tool are duralumin 2A12,1 He of 1# detecting tool that such material is done
2# detecting tool 2 is unlikely to deform and intensity is high.
1 lateral layout of 1# detecting tool has a threaded hole 6, and unsintered tape 7 will be wound at pneumatic 3 screw thread of thread straight-through connector
After be installed on threaded hole 6；The steam hose 8 of leak detector 4 is connected to pneumatic thread straight-through connector 3；By 5 valve of built-in motor valve
11 close, and by built-in motor valve 5 with 1#O type circle 9 air inlet at be mounted in 1# detecting tool 1.1# detects work at this time
Filling 1 inner space is closed space, and after instrument 4 of stopping leakage in the roof starts, leak detector 4 can ventilate to 1# detecting tool 1, thus detecting
When, gassy in 1 inner space of 1# detecting tool, the gas filled to inspection 1 inner space of 1# detecting tool passes through leak detection
Instrument 4 controls certain pressure, and the size of pressure is depending on detection pressure required by built-in motor valve 5.When 1# detecting tool 1
Instrument 4 of stopping leakage in the roof is observed after the interior pressure for applying calibration shows data, when leakage rate is greater than requirement data set by leak detector 4,
Leak detector 4 can issue unqualified prompt and with too sound；When leakage rate is less than or equal to requirement set by instrument 4 of stopping leakage in the roof
When data, instrument 4 of stopping leakage in the roof can prompt qualification.The fit dimension of the 1# detecting tool 1 and built-in motor valve 5 is according to built-in motor
9 size of 1#O type circle at the air inlet of valve 5 and change, can be good at guaranteeing its leakproofness after cooperation.
The above are 5 inner sealing detection methods of built-in motor valve.
Embodiment 2: 5 valve 11 of built-in motor valve is opened, and built-in motor valve 5 is installed to the side of 1#O type circle 9
1# detecting tool 1, the other side with 2#O type circle 10 are installed to 2# detecting tool 2, and, with embodiment 1, the above are built-in for other
5 outside method for conducting leak test of motor valve.
5 outside sealing propertytest of built-in motor valve is depending on the design feature of built-in motor valve 5, some built-in motor valves
5 do not have to detect external leakproofness, should be detected according to the practical situation of built-in motor valve 5.
The device for detecting sealability and method that present embodiment provides, by the gas in simulation actual environment, to built-in
Motor valve leakproofness is detected.The method for conducting leak test uses the built-in motor valve device for detecting sealability, tool
Have the characteristics that simple and effective.
The above is preferred embodiments of the present invention, it is noted that for the ordinary skill of the art
For personnel, without departing from the principle of this utility model, several improvement etc. can also be made, these improvement are also considered as this
The protection scope of utility model.
