Abstract
The utility model discloses a multi-port pressure gage test stand which comprises an oil cup, a hand pump and parallel-connection test pipelines, wherein the oil cup is connected with a rodless cavity of the hand pump through an oil supply pipeline, and the rodless cavity of the hand pump is connected with the five parallel-connection test pipelines through a connection pipe. A gage valve and a standard gage port are sequentially connected onto one parallel-connection test pipeline in series, and a standard gage is arranged on the standard gage port. A gage valve and a test gage port are sequentially connected onto each of the other four parallel-connection test pipelines in series, the four test gage ports include three standard pressure gage ports and one English standard pressure gage port, and a needle valve is arranged between the connection pipe and the oil supply pipeline. The multi-port pressure gage test stand is provided with four test gage ports for selection, is simple to operate, improves test efficiency and is prolonged in service life.
Description
Technical field
The utility model relates to a kind of tensimeter testing table, particularly relates to a kind of multiport tensimeter testing table.
Background technology
The hand piston pressure meter calibration stand all is two man-to-man designs of interface usually: an interface dress standard scale, an interface dress is by checklist, conventional equipment for daily verification test in the manometer gage work, but for tensimeter factory and the construction of construction and installation project instrument, because manometer model, the quantity of installing are a lot, construction period is tight, and increasing along with present joint venture, external manometric inch screw thread joint is very common, and the working-yard is not easy supporting such connector.Under tight execution conditions of large duration of workload, conventional single interface piston pressure checking table just seems that efficient is low, complex operation, make experiment work dull, and in a large amount of pressure checking table pressure testing tests, the rubber sealing ring of piston pressure pump is easy to wear-out failure in using frequently, makes the work efficiency reduction even experiment work is stagnated.
The utility model content
The technical problems to be solved in the utility model provides the multiport tensimeter testing table that a kind of efficient is high, simple to operate, the life-span is long.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of multiport tensimeter testing table, comprise lubricating cup, wobble pump, the Parallel test pipeline, lubricating cup is communicated with the rodless cavity of wobble pump through oil feed line, the rodless cavity of wobble pump is through connecting pipe and five Parallel test pipeline connections, meter in series valve successively on Parallel test pipeline wherein, the standard scale port, installation code table on the standard scale port, meter in series valve successively on other Parallel test pipelines, the test card port, four test card ports are respectively three master gauge ports and an inch standard tensimeter port, between connecting pipe and the oil feed line needle valve are installed.
Multiport tensimeter testing table of the present utility model, connect successively on the wherein said oil feed line filter screen, non-return valve.
The utility model multiport tensimeter testing table, being designed with 4 road test card ports can be for selecting, and operates simplyr, has improved test efficiency, has prolonged the serviceable life of instrument testing table.
Below in conjunction with accompanying drawing multiport tensimeter testing table of the present utility model is described further.
Description of drawings
Fig. 1 is the systematic schematic diagram of the utility model multiport tensimeter testing table.
Embodiment
As shown in Figure 1, the utility model multiport tensimeter testing table comprises lubricating cup 1, wobble pump 5, non-return valve 3, Parallel test pipeline 11, lubricating cup 1 is communicated with through the rodless cavity of oil feed line 12 with wobble pump 5, the filter screen 2 of connecting successively on the oil feed line 12, non-return valve 3, the rodless cavity of wobble pump 5 is communicated with five Parallel test pipelines 11 through connecting pipe 4, meter in series valve 9 successively on four Parallel test pipelines 11 wherein, test card port 8, meter in series valve 91 successively on another Parallel test pipeline, standard scale port 81, installation code table 6 on the standard scale port 81 is installed needle valve 10 between connecting pipe 4 and the oil feed line 12.Four test card ports 8 are respectively three master gauge ports (M20*1.5) and an inch standard tensimeter port (G1/2 ").
The utility model multiport tensimeter testing table, to be installed in test card port 8 by checklist 7 during detection, lubricating cup can be according to being injected castor oil or transformer oil by the pressure model of checklist during work, when tensimeter is tested, test in wobble pump 5 is pumped to pump housing rodless cavity, is equipped with a non-return valve 3, during applied voltage test with Medium Oil between lubricating cup 1 and wobble pump 5, needle valve 10 is closed, and Medium Oil flows into Parallel test pipeline 11 through connecting pipe 4 and tests.
The utility model multiport tensimeter testing table, being designed with 4 road test card ports according to the test needs can be for selecting, no port is closed corresponding instrument valve 9 at the trial and is got final product, according to law of connected vessels, when Medium Oil flows into test card port 8 through connecting pipe 4 and gauge valve 9, make standard scale 6 and be calibrated table 7 indication corresponding numerical value (standard scale 6 is identical with the pressure that is calibrated table 7 in theory), the manual adjustments piston pump, carry out standard scale 6 and the Comparison calibration test that is calibrated table 7 by boosting with step-down, and the record experimental data.
The utility model multiport tensimeter testing table can carry out opening needle valve 10 after having tested with the manometric test calibration of the 1-4 piece of range simultaneously, shakes piston pump, the Medium Oil in the pipeline is drawn back lubricating cup, in order to next time test.
Above-described embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of the utility model claims.
