Abstract
The utility model relates to a vacuum pressure test fixture which is characterized by comprising a vacuum valve, a control valve, a product link port and a control system, wherein the vacuum valve, the control valve and the product link port are connected sequentially through pipelines, the product link port is connected with products to be tested, the control system is communicated with the vacuum valve and the control valve separately, a vacuum degree meter and a test meter are arranged between the product link port and the control valve. According to the vacuum pressure test fixture, the vacuum valve is used as a vacuum generating system, and the pump-down time and the test time are controlled through a pipeline control system, so that the test accuracy is high, the noise is low, and the communication function is also provided.
Description
Technical field
The utility model relates to a kind of pressure test tool, especially relates to a kind of vacuum pressure measurement jig of electronic product, is used for the water resistance of detected electrons product, belongs to pressure test tool technical field.
Background technology
In the prior art, the method for waterproof product vacuum test commonly used is done air tightness test, and traditional tool manufacturer adopts noise bigger when doing the testing water-proof product tool usually, and cost is than higher vacuum pump, and measuring accuracy is poor.
Summary of the invention
For solving the deficiency of prior art, the purpose of the utility model is to provide the vacuum pressure measurement jig that a kind of measuring accuracy is high, noise is low, cost is low.
For achieving the above object, the utility model is to realize through following technical scheme:
The vacuum pressure measurement jig; It is characterized in that; Comprise vacuum valve, operation valve, product connectivity port and control system, vacuum valve, operation valve and product connectivity port are linked in sequence through pipeline, and described product connectivity port is connected with product to be measured; And described control system is communicated with vacuum valve and operation valve respectively, between product connectivity port and operation valve, also is provided with vacuum meter and test chart.
Described control system comprises and vacuumizes chronotron and test chronotron that the described chronotron that vacuumizes all is communicated with described vacuum valve and operation valve with the test chronotron, in order to control pumpdown time and test duration.
In addition, on the pipeline between described operation valve and the vacuum valve, also be connected with baffle-box.
And that described connectivity port can also be provided with is a plurality of, is connected with operation valve through pipeline respectively.
The beneficial effect of the utility model is: the utility model adopts vacuum valve as vacuum generating system, carries out the control of pumpdown time and test duration through air-path control system, makes that measuring accuracy is high, noise is low and have communication function.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment.
The main mark implication is following in the accompanying drawing:
1, operation valve 2, baffle-box 3, vacuum valve 4, pipeline
5, test chart 6, vacuum meter 7, control system 8, product connectivity port.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done concrete introduction.
Fig. 1 is the structural representation of the utility model one embodiment.
As shown in Figure 1: the vacuum pressure measurement jig; Comprise vacuum valve 3, operation valve 1, product connectivity port 8 and control system 7; Vacuum valve 3, operation valve 1 and product connectivity port 8 are linked in sequence through pipeline 4; Described product connectivity port 8 is connected with product to be measured, and described control system 7 is communicated with vacuum valve 3 and operation valve 1 respectively, between product connectivity port 8 and operation valve 1, also is provided with vacuum meter 6 and test chart 5.
Above-mentioned control system 7 comprises and vacuumizes chronotron and test chronotron that the described chronotron that vacuumizes all is communicated with described vacuum valve 3 and operation valve 1 with the test chronotron, in order to control pumpdown time and test duration.
In addition; On the pipeline between described operation valve 1 and the vacuum valve 3, also be connected with baffle-box 2, be used for moment of closing, if the outside has gas to get at operation valve 1 and vacuum valve 3; Then baffle-box then can cushion; And can not let gas get into the pipeline 4 between operation valve 1 and the product connectivity port 8, therefore, can not cause to measure and forbidden.
In addition, above-mentioned connectivity port 8 can also be provided with a plurality of, is connected with operation valve 1 through pipeline respectively, with test pipeline and the product connectivity port 8 that forms a plurality of parallel connections, can carry out the performing leak test of a plurality of products.
The course of work of the utility model is: at first product to be measured is connected on the product connectivity port 8, opens solenoid valve 3 and operation valve 1 then, total system is vacuumized, the moment that solenoid valve 3 and operation valve are being started working; To vacuumizing the chronotron transmission signals, vacuumize the chronotron timing and begin, arrived the time of setting after, control system control vacuum valve 3 cuts out with operation valve 1; Quit work, after testing chronotron then and receiving signal, pick up counting, reach the test duration after; The product test process finishes, and in the process that vacuumizes, vacuum meter 6 shows the vacuum tightness reading; In test process, test chart 5 shows the vacuum tightness reading, if the vacuum tightness reading that test chart 5 shows is in the scope of regulation; Then the water resistance of product has reached requirement, otherwise, then do not reach requirement.
The utility model adopts vacuum valve 3 as vacuum generating system, carries out the control of pumpdown time and test duration through air-path control system, makes that measuring accuracy is high, noise is low and have communication function.
The foregoing description does not limit the utility model in any form, and all employings are equal to the technical scheme that mode obtained of replacement or equivalent transformation, all drop in the protection domain of the utility model.
