In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0046] like Figure 1 and Figure 2 As shown, this embodiment provides a water pressure testing method. The method includes the following steps:

[0047] S100, connecting the internal water channels of a plurality of workpieces 10 to be tested in series through a pipeline 10;

[0048] S200, connecting one end of the pipeline 10 to the flushing device 20, and the other end to the water outlet pipe 30, the water outlet pipe 30 is provided with a switch valve 50, and connecting the detection device 40 to the pipeline 10;

[0049] S300, close the switch valve 50 and perform water pressure detection;

[0050] S400, perform pressure holding test;

[0051] S500 , draining the water from the plurality of workpieces 100 to be tested and the pipeline 10 .

[0052] When the above method is used for water pressure testing, since the internal water channels of the multiple workpieces 100 to be tested are connected in series with the pipeline 10, after the flushing device 20 is opened, the water flow can flow along the pipeline 10 to the interior of the multiple workpieces 100 to be tested, so as to perform subsequent testing, thereby avoiding the situation where each workpiece 100 to be tested needs to be individually connected to the detection device 40 and the flushing device 20, thereby saving the pipeline 10 and the installation steps; correspondingly, after the test is completed, the water in all the workpieces 100 to be tested can be completely drained through the switch valve 50, without the need to drain the water one by one, thereby greatly improving the operating efficiency and testing speed.

[0053] It should be noted here that, in order to ensure the convenience of use, the multiple workpieces 100 to be tested can be detachably connected to the pipeline 10. A detachable relationship can be formed by a clamp connection or a threaded connection, which is not specifically limited in this embodiment. The detachable connection method can facilitate subsequent maintenance and replacement, thereby improving convenience.

[0054] Before testing, it is necessary to flush water into the multiple workpieces 100 to be tested through the pipeline 10. However, if there is a small amount of gas inside the workpiece 100 to be tested, the water flow will not be able to smoothly enter the interior, resulting in low detection accuracy. To solve this problem, step S200 also includes step S210, which specifically opens the switch valve 50 and the flushing device 20, and the water flow can flow through the pipeline 10 and the multiple workpieces 100 to be tested, so that the water flow can discharge the gas in the multiple workpieces 100 to be tested. This method is not only simple to operate, but also can efficiently discharge the gas inside the workpiece 100 to be tested, ensuring that the subsequent test can be successfully completed.

[0055] In addition, step S200 also includes step S220, that is, when water flows through the pipeline 10 and the multiple workpieces 100 to be tested, it is possible to detect whether there is water leakage at the connection between the workpiece 100 to be tested and the pipeline 10. This step can ensure that the pipeline 10 and the workpiece 100 to be tested are well connected before the test, and can effectively deal with the leaking connection in time to ensure a tight connection effect, thereby ensuring a good and accurate test effect.

[0056] After completing the above operations, it is necessary to perform a test, and the corresponding step S300 includes S310 and S320, wherein the step S310 is to observe the displayed number of the detection device 40. When the displayed value is equal to the preset pressure value, the multiple workpieces 100 to be tested are all finished products; the step S320 is to observe the displayed number of the detection device 40. When the displayed value is equal to the preset pressure value, the multiple workpieces 100 to be tested are defective products. In this process, the detection device 40 is connected to the pipeline 10, and can detect and display the actual pressure in the pipeline 10. When the value of this actual pressure is equal to the preset pressure value, it proves that the air tightness of the multiple workpieces 100 to be tested meets the actual processing standards, and then it can be judged that they are all finished products. When the value detected and displayed by the detection device 40 is different from the preset value, it proves that there are defective products with poor air tightness among the multiple workpieces 100 to be tested.

[0057] Correspondingly, in order to facilitate the determination of which of the multiple workpieces 100 to be tested is a defective product with poor airtightness, step S300 also includes S330, that is, when the displayed number is not equal to the preset pressure value, the workpiece 100 to be tested that is leaking is determined to be a defective product with poor airtightness. Since the switch valve 50 is in a closed state, when there is a problem with the airtightness of the workpiece 100 to be tested, a water leakage problem will occur, and then it can be determined that the workpiece 100 to be tested that is leaking is a defective product.

[0058] To detect whether a batch of samples is qualified, their pressure bearing capacity must also be tested. In this regard, a pressure holding test of step S400 is proposed. Step S400 includes S410 and S420, wherein S410 is to close the flushing device 20, the water pressure between the flushing device 20 and the switch valve 50 is kept constant, and multiple workpieces 100 to be tested are all judged to be finished products. S420 is that the water pressure between the flushing device 20 and the switch valve 50 changes, and there are defective products among the multiple workpieces 100 to be tested. In step S410, the water pressure between the flushing device 20 and the switch valve 50 is also the water pressure in the pipeline 10. If the detection device 40 can detect that the pressure value remains constant within a period of time, it proves that the workpiece 100 to be tested has a certain pressure holding capacity and can be judged as a finished product; if the display value of the detection device 40 changes during this period of time, it proves that there are defective products with insufficient pressure bearing capacity among the multiple workpieces 100 to be tested.

[0059] Correspondingly, in order to facilitate the determination of which of the multiple workpieces 100 to be tested is a defective product with weak pressure bearing capacity, step S400 also includes S430, that is, when the water pressure between the flushing device 20 and the switch valve 50 changes, the leaking workpiece 100 to be tested is determined as a defective product. When the pressure bearing capacity of the workpiece 100 to be tested is weak, it cannot continuously maintain the pressure, which will cause local cracks, etc., and then water leakage will occur. Therefore, according to which specific workpiece 100 to be tested is leaking, it can be determined which one is a defective product with weak pressure bearing capacity. The operation is simple and the result is intuitive.

[0060] After completing the above operations, the entire test process can be realized, and drainage can be performed at this time. Step S500 includes S510, that is, opening the switch valve 50 to connect the pipeline 10 with the water outlet pipe 30 for drainage. In this step, the problem of draining water one by one for multiple workpieces 100 to be tested is omitted, thereby improving the overall work efficiency and reducing the working time.

[0061] In addition, step S500 further includes S520, connecting the water outlet pipe 30 to the water storage tank of the flushing device 20. According to this step, water can be recycled, reducing costs and saving resources.

[0062] In summary, the water pressure testing method in this embodiment can flush water quickly with high efficiency and can drain water quickly, thereby improving detection efficiency.

[0063] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here.
