Between water tank 11.
Further, the electronic balance 13 is located at 11 bottom of water tank.
Further, the detection device further includes second branch 20, and described 20 one end of second branch and the water tank 11 connect
It connects；The end of the other end is connect with the first branch 10, and the end of the other end is located at the air-driven hydraulic pump 14 and institute
It states between pneumatic stopping valve 15；
Transparent pipe 21, flow restriction control valve 22, pneumatic liter/pressure-relief valve 23 are disposed in the second branch 20, it is described
Transparent pipe 21 is close to the water tank 11, and the pneumatic liter/pressure-relief valve 23 is close to the second branch 20.
Further, the detection device further includes third branch, and one end of the third branch is connect with the water tank 11,
The other end of the third branch is connect with the first branch 10, and the end of the other end of the third branch is close to described
Pressure sensor 17, the third branch road are equipped with Manual pressure relief valve.
Further, the detection device further includes control cabinet and hydraulic fluid tank, the first branch 10, the second branch 20
It is arranged in the hydraulic fluid tank with the third branch, the control cabinet is electrically connected with the hydraulic fluid tank, so that the control
Case controls the first branch 10, the second branch 20 and the third branch in the hydraulic fluid tank.
Specific embodiment: mobile gas cylinder internal test method water pressure test detection device, mainly include control cabinet and hydraulic fluid tank,
Control cabinet mainly includes the equipment such as computer, display, and control cabinet and hydraulic fluid tank are electrically connected, to control in hydraulic fluid tank
Each road equipment open or close state.
The first branch 10, second branch 20 and third branch are placed in hydraulic fluid tank, thus the entire detection device made
It is easy to remove, and then detection device can be made to be able to detect the gas cylinder in some special occasions.
The first branch 10 of detection device is main road, and connects water tank 11, other end connection in one end of the first branch 10
By trial jar 19, by the way that air-driven hydraulic pump 14, pneumatic stopping valve 15, pressure sensor 17, close pressure are arranged in the first branch 10
Power table to measure the data of gas cylinder during the experiment in real time；Electronic balance 13 also wherein is set in 11 bottom of water tank, for real
When monitoring water tank 11 in water variation；And temperature sensor 12 is set in water tank 11, water temperature in real-time monitoring water tank 11
Variation, in order to keep the structure of the present apparatus more compact, therefore temperature sensor 12 is arranged in the first branch 10, and temperature passes
Sensor 12 is proximate to water tank 11.
The air-driven hydraulic pump 14 of the present apparatus uses double acting air-driven hydraulic pump 14, and operator has surprisingly found that, by setting
Setting double acting air-driven hydraulic pump 14 can make the testing result of the present apparatus more accurate, during operator constantly explores
It was found that the existing power three plunger electrodynamic pumps that commonly use boost, but three plunger electrodynamic pumps are during the test,
Since the position shut down every time is different, so that the water retained in pump is different, and then cause in the variation for measuring water
There is a certain error in journey, and then influence entirely to test as a result, and operator using double acting air-driven hydraulic pump 14
Afterwards, because of the special construction of double acting air-driven hydraulic pump 14, as shown in the figure, no matter shut down when, the water in pump is all
Constant, thus reduce because in pump water it is different due to caused by error, and then avoid a possibility that experimental result is inaccurate,
Therefore the accuracy rate that experiment can be effectively improved using double acting air-driven hydraulic pump 14, especially can be improved rate of residual
Accuracy rate.
The second branch 20 of this detection device, includes pneumatic liter/pressure-relief valve 23, flow restriction control valve 22 and transparent pipe 21,
During experiment, often there is more fortuitous event and occur, such as by the tie point of trial jar 19 and the first branch 10
In the presence of unsteady situation is connected, will carry out unloading press operation on the way in experiment, and second branch 20 can do special circumstances
Emergency relief processing, is adjusted the pressure in whole device by opening pneumatic liter/pressure-relief valve 23 and flow restriction control valve 22,
Pass through the more intuitive the case where observing adjusting of transparent pipe 21.
In previous stress-relief process, carried out by the filter 16 in the first branch 10 to by the water in trial jar 19
Filter found by the long-term and unremitting effort of operator, by usually containing more anvil cinder in the water in trial jar 19, and it is tested
Water in bottle 19 flows back during water tank 11, and its equipment for being easy each road of blocking, influences subsequent detection device
Use, therefore this detection device setting filter 16 be unidirectional filter 16, can only for by trial jar 19 water flow back
To water tank 11, play filtering, the reason of so as to avoid because of anvil cinder, the entire detection device service life is caused to shorten
The problem of.
The third branch road setting Manual pressure relief valve of the present apparatus, main function are manual releases when generation emergency is.
It is easy to remove that the bottom of the hydraulic fluid tank of the present apparatus also sets up idler wheel, pull rod is also set up at the top of hydraulic fluid tank, convenient for taking
Band.
Specific test procedure is as follows；
The first step first carries out the equipment in the equipment and control cabinet in hydraulic fluid tank when to being detected by trial jar 19
Detection, and connect；
Second step will be connected to the end of the first branch 10 by trial jar 19, start to test, closes pneumatic liter/pressure-relief valve 23,
And start double acting air-driven hydraulic pump 14, so that the first branch 10 is gradually boosted, shut down after reaching specified pressure, and close pneumatic
Shut-off valve 15 opens pneumatic liter/pressure-relief valve 23, carries out pressure maintaining, and pass through temperature sensor 12, electronic balance 13, pressure sensing
Device 17 and compacting pressure table obtain corresponding data, test corresponding data, in order to keep the effect of pressure maintaining more preferable, therefore are shutting down
Afterwards, double acting air-driven hydraulic pump 14 is kept apart, and de-ballast pump end pressure, leak source is unloaded in reduction, to reach pressure holding effect very
Good effect.
Third step, pressure maintaining reach after a certain period of time, open pneumatic stopping valve 15, start release, during release, lead to
The flow that throttling regulating valve 22 limits release under high pressure is crossed, to avoid because return pressure process recirculation water is gone out in stress-relief process
Water tank 11, a possibility that causing test failure, and pass through temperature sensor 12, electronic balance 13, pressure sensor 17 and close
Pressure gauge obtains corresponding data, finally feeds back in control cabinet, calculates test result data.
The present apparatus is easy to carry and mobile, can be effectively solved in the prior art because special occasions cannot do gas cylinder test
Operation, and the present apparatus can measure corresponding data in real time, so that the present apparatus testing efficiency made is high.
While there has been shown and described that the embodiments of the present invention, it will be understood by those skilled in the art that
Are as follows: these embodiments can be carried out with a variety of variations, modification, replacement in the case where not departing from the principles of the present invention and objective and become
Type, the scope of the utility model are defined by the claims and their equivalents.
