It is simple that the utility model object provides a kind of structure, by vacuumizing the sealing property detecting valve with inflatable body two kinds of modes, improves accuracy of detection, can improve the technical scheme of the dirigibility of detection simultaneously:
A kind of high pressure valve sealing property detection device, mainly comprise air pump, pipe, the first valve, the second valve, valve to be measured and tank, one end of pipe connects air pump gas outlet, the gas humidity detector that pipe is provided with the first valve, detects the gas gauge of gaseous tension in pipe, detects gas humidity, the pipe other end connects valve to be measured, and valve to be measured is by three-way pipeline connection water channel and pressure tester respectively.
As preferably, arrange the second valve pressure measuring device between three-way pipeline and pressure tester and be provided with pressure tap, the second valve is connected with pressure tap.
As preferably, pressure tester is pointer micromanometer or pressure transducer.
As preferably, valve one end to be measured is connected with pipe port with the first hoop by the first drum rim, and the valve other end to be measured passes through the second drum rim and is connected with flexible pipe with the second hoop, and flexible pipe is connected with three-way pipeline.
As preferably, air pump is pressurized air air pump or vacuum pump.
The beneficial effects of the utility model are:
(1) the utility model structure is simple, and the air pump of employing is pressurized air air pump or vacuum pump, by vacuumizing the sealing property detecting valve with inflatable body two kinds of modes, can improve accuracy in detection.
(2) the utility model arranges pressure tester between valve to be measured and tank, gas leakage can be detected in time when valve leak to be measured, improves the dirigibility of detection.
accompanying drawing illustrates:
Fig. 1 is systematic schematic diagram of the present utility model.
embodiment:
For making goal of the invention of the present utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
As shown in Figure 1, a kind of high pressure valve sealing property detection device, mainly comprise air pump 1, pipe 2, first valve 3, second valve 4, valve to be measured 5 and tank 6, air pump 1 is pressurized air air pump or vacuum pump.One end of pipe 2 connects air pump 1 gas outlet, pipe 2 is provided with the first valve 3, detect the gas gauge 7 of gaseous tension in pipe, detect the gas humidity detector 8 of gas humidity, pipe 2 other end connects valve 4 to be measured, valve 4 to be measured is by three-way pipeline 6 connection water channel 10 and pressure tester 11 respectively, second valve 4 is set between three-way pipeline 6 and pressure tester 11, pressure tester 11 is provided with pressure tap 111, second valve 4 is connected with pressure tap 111, valve 5 one end to be measured is connected with pipe 2 port with the first hoop 52 by the first drum rim 51, valve 5 other end to be measured is connected with flexible pipe 9 with the second hoop 54 by the second drum rim 53, flexible pipe 9 is connected with three-way pipeline 6, pressure tester 11 is pointer micromanometer or pressure transducer.
During detection, in tank 10, load a certain amount of water.Two ports of valve 5 to be measured are sealedly connected on pipe 2 and flexible pipe 9 respectively by the first drum rim 51 and the first hoop 52, second drum rim 53 and the second hoop 54.Now, the first valve 3 on pipe 2 is in open mode, and the second valve 4 is open mode.First the first valve 3 on pipe 2 is closed, start pressurized air air pump, inflate in pipe 2, when gas gauge 7 reaches certain value, need to close the first valve 3 on pipe 2, close valve 5 to be measured, and the change of the pressure observing pressure tester 11 pressure sensor detect within a period of time, thus can detect whether valve 5 to be measured leaks.When adopting vacuum pump, close the second valve 4, close valve 5 to be measured, open the first valve 3, booster air pump 1, vacuumize in pipe 2, when gas gauge 7 reaches certain value, need to close the first valve 3 on pipe 2, if valve 5 to be measured has leakage, in pipe 2, gaseous tension diminishes, and the water in tank 10 can enter in pipe, and within a period of time, observe the change of gas humidity detector 8, if gas humidity becomes large, then represent that valve 5 to be measured leaks, water enters in pipe, causes gas humidity to become large.The utility model structure is simple, the air pump adopted is pressurized air air pump or vacuum pump, can by vacuumizing the sealing property detecting valve with inflatable body two kinds of modes, improve accuracy in detection, pressure tester is set between valve to be measured and tank simultaneously, gas leakage can be detected in time when valve leak to be measured, improve the dirigibility of detection.
