Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, a kind of watertightness performance testing inspection of the utility model system, comprising: water supplying unit, its outlet is communicated with testing container 3 by pipeline, and water supplying unit is used for providing pressure stability and the water source of pressure adjustable joint to testing container 3; Flow detection unit, is arranged on the pipeline between described water supplying unit and testing container 3, and flow detection unit is used for the fluctuations in discharge in signal piping, and testing result is fed back; Alarm unit, is connected with flow detection unit, for receiving the signal of flow detection unit feedback, and judges whether to give the alarm.
Concrete, described flow detection unit comprises sensor 4 and is connected to described sensor 4 imports and exports the first valve 7 and the second valve 9 on pipeline, and sensor 4 is for the water volume flow rate in signal piping.And described flow detection unit is parallel with branch road, described branch road is provided with the 3rd valve 8.Before test, need, first to water filling in testing container 3, to close the first valve 7 and the second valve 9, open the 3rd valve 8 on branch road, open the solenoid valve between variable frequency pump 1 and accumulator 2, start water filling; The water of the pressure stability that accumulator 2 flows out directly enters testing container 3 from branch road, until the vent port of testing container 3 there are flowing out, illustrates in testing container 3 and is full of water, shut electromagnetic valve, stops water filling, and closes the vent port of variable frequency pump 1 and testing container 3.In the injecting process, current are without sensor 4, play the object of protection sensor 4, extend its serviceable life.
Described alarm unit comprises the processor 5 be connected with described sensor 4 and the hummer 6 be connected with described processor 5; The information that described processor 5 detects for receiving, processing described sensor 4, and judge whether to send alarm command to hummer 6 according to result; Described hummer 6 is for the alarm command that receives described processor 5 and send and give the alarm.Described processor 5 is connected with display module, for showing the water volume flow rate that described sensor 4 detects.
As shown in Figure 2, after water filling terminates, close the 3rd valve 8, open the first valve 7 and the second valve 9, make current through the probe of sensor 4; According to the pressure values of operating mode free setting primary pressure, final pressurization value, pressure difference, voltage stabling control step by step between pressurization, build the pressure the parameters such as time, open variable frequency pump 1 to pressurize, when the pressure in pipeline reaches setting value, the rotating speed of adjustment variable frequency pump 1, makes manifold pressure keep stable; Then system enters the state of building the pressure, build the pressure certain time, build the pressure in process, the flow velocity of water in the real-time testing pipes of sensor 4, and change the data measured into electric signal and feed back to processor 5, processor 5 pairs of data process, and obtain the flow parameters in pipeline, and are transferred to display module and show; If the flow parameter after process exceedes setting value, illustrate that testing container 3 has leakage, processor 5 sends alarm command signal, and hummer 6 Received signal strength starts to give the alarm.
Do not report to the police in process if build the pressure, illustrate that container does not leak, now continue pressurization, repeat above-mentioned steps, again carry out voltage stabilizing, build the pressure, detect operation, until pressurization value reaches final pressurization value, if No leakage, then measured; If find that there is flow variation in measuring process or report to the police, then testing container 3 is defective.
Described water supplying unit comprises variable frequency pump 1 and accumulator 2, and described accumulator 2 is communicated with the outlet of variable frequency pump 1 and flow detection unit respectively; Variable frequency pump 1 is for providing the current of pressure adjustable, and accumulator 2 is for the pressure of stationary flow.Pipeline between described variable frequency pump 1 and accumulator 2 is connected with solenoid valve.Variable frequency pump 1 can provide the water of different pressure, but its water pressure fluctuations of discharging is comparatively large, and cannot be directly used in detection, therefore connect accumulator 2 later, the glassware for drinking water that water supplying unit is discharged has stable pressure, ensures normally carrying out of detection; For convenience of controlling, simultaneously in order to protect variable frequency pump 1, the pipeline between variable frequency pump 1 and accumulator 2 is provided with solenoid valve; at the end of test; first shut electromagnetic valve, then close variable frequency pump 1, when avoiding pressure release, in pipeline, pressure declines suddenly and to cause damage to variable frequency pump 1.
The entrance of described variable frequency pump 1 is connected with tank, and described tank is provided with moisturizing module and for by drainpipe thoroughly emptying for tank.Described moisturizing module comprises: liquid supply device and the liquid level gauge for measuring tank liquid level, and described liquid level gauge is electrically connected with described liquid supply device; Described liquid supply device is used for carrying out moisturizing when tank reaches low liquid level, and stops moisturizing when tank reaches high liquid level.This arranges and can ensure to have in testing process continuously water source for variable frequency pump 1, to ensure normally carrying out of detection.
For the ease of transport, conveniently the testing container 3 being arranged on diverse location is tested, described flow detection unit and alarm unit are installed on same moveable carriage, easy to use.
As can be seen from the above embodiments, the utility model, by continuing the water passing into different pressure in testing container 3, has fluctuations in discharge when detecting on supply channel simultaneously, thus the sealing of simulation container under different pressure.The utility model can simulate the pressure values of the known water surface degree of depth, and test result is truer; The utility model goes for the performing leak test of engineering construction field, in order to measure the impervious parameter of closed container under water, also can be used on vessel fabrication enterprise in order to detect the sealing of its product.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and replacement, these improve and replace and also should be considered as protection domain of the present utility model.
