Testing stand, belong to the field of measuring technique of flow.
Background technology
National Specification, the water meter that every production is dispatched from the factory, which has to pass through, tests table test step.And this procedure is almost
Account for the 50% of water meter production hour.So the production capacity of a water meter factory is typically by being determined with the production capacity for testing table test
's；In other words, production capacity is by water meter check test device（Fig. 1）Number of units determine.
Traditional large quantities of water gauge Product checkings, usually the water meter that 4-5 platforms need to detect is connected with short tube, clamping exists
Water meter is tested on table testboard, and verification water meter is tested by the way that flow velocity is the stable current of Q1, Q2, Q3, Q4.
Due to low discharge Q1, Q2 than big flow Q3、Q480 times to more than 200 times are at least differed, low discharge Q1、Q2's
The time needed for water meter is examined almost to account for examining more than the 95% of water meter man-hour.
The Q of big flow3、Q4It is bigger by the pressure loss of water meter.The pressure loss of water meter, it is to restrict when water meter verifies
Water Meter quantity can only 4-5 platforms key reason.
The Q of low discharge1、Q2It is almost nil by the pressure loss of water meter.Then there is the special of 20-30 platform water meters of connecting
Door detection low discharge Q1、Q2Water meter test table testboard.By low discharge and big flow test process, respectively in two clampings（Water meter
Quantity）The different water meter of ability tests the operation of table testboard, though improve the efficiency of water meter detection.But this method exist it is following
Shortcoming：
1) by loading and unloading a water meter, the task for loading and unloading water meter twice is increased to.Particularly often load and unload the wired electricity of 4-5 platforms
During sub- water meter, it is also necessary to plug 64-80 joint line（The bus of every electronic water meter has 4 cores）Time；
2) water meter is tested into table testboard with short tube series connection clamping in water meter（Taken out stitches with wiring）Time, almost account for whole inspections
Test the time more than 40%.
The content of the invention
The utility model proposes it is a kind of for electronic water meter test table test water meters in series connection testing stand the purpose is to for
Solve the defects of water meter present in prior art tests table detection efficiency deficiency, part, to improve water meter product detection efficiency, again
Increase water meter tests the frock clamp of table testboard utilization rate.
Technical solution of the present utility model：Water meters in series connection testing stand, its structure includes total line bracket, bus plug is inserted
Seat, pipe joint, pipe connect balladeur train, end support, 1 pair of water meter axial guidance with locking device, wherein total line bracket and bus plug
One end of socket connects, the other end pipe joint of bus plug socket, and the pipe on pipe joint connects sliding linking end support.
The advantages of the utility model：
1) more movable water meters in series connection testing stands can be manufactured, it has 1 pair of water meter axial guidance with locking device.
Each water meters in series connection testing stand, can be with independently installed 4-5 platforms water meter；
2) rill water gauge check test device workbench, can be with the water meter of 4-6 water meters in series connection testing stand of clamping（20-
30 tables；
3) for the water meters in series connection testing stand of Wired electronic water meter test, there is a total line bracket on testing stand.Bus
There are 5 total wire clamp seats of 4 cores being connected in series on support, the communication bus of 5 water meters of water meter test group can be accessed；Before and after bus
Respectively there is 1 bus plug socket at both ends, can be with the bus of connecting detection computer, or connect other water meters in series connection testing stands
Bus；
4) clamping of water meter, due to not carried out on water meter check test device, water meter check test device is improved
Utilization rate of equipment and installations.Meanwhile the clamping set-up procedure of water meter check test work also accordingly reduces by 4/5 time.
