DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0030] When the pulse electromagnetic valve is detected, the durability of the valve needs to be detected. The existing detection operation is only to open and close the valve for more than 100 times, and then observe whether the action of the valve is consistent. However, in the use process, the water flow may impact the valve at multiple angles or in multiple styles, and thus the detection method is difficult to comprehensively test the pulse electromagnetic valve.

[0031] Therefore, the present application provides a pulse electromagnetic valve test bench and a detection method, as shown in Figures 1-5 The utility model discloses a pulse electromagnetic valve test bench and a detection method, as shown in

[0032] When the pulse electromagnetic valve body 6 needs to be tested, it can be placed on the support assembly, then the water tank 1 introduces water flow into the turbulence mechanism through the flow guide mechanism, then the water flow can be transformed into a spiral shape into the inside of the pulse electromagnetic valve body 6, and then when the valve inside the pulse electromagnetic valve body 6 is opened and closed, the state of the water flow can be changed to test it. When the turbulence assembly is not enabled, the water flowing into the inside of the pulse electromagnetic valve body 6 can directly hit the valve inside the pulse electromagnetic valve body 6, and the turbulence mechanism can be intermittently opened and closed, thereby improving the changing state of the water flow during the test process, and the test of the pulse electromagnetic valve body 6 can be more comprehensive.

[0033] Specifically, referring to Figures 1-5 As shown in the figure, the turbulence mechanism includes a water inlet pipe 7, a flow guide pipe 8, a sealing ring pad 9, a groove 10, a baffle 11, an arc-shaped turbulence plate 12, a limiting plate 13, a rotating assembly, the pulse electromagnetic valve body 6 is fixedly connected with the water inlet pipe 7 at the end, the water inlet pipe 7 is slidably connected with the flow guide pipe 8 at the end, the flow guide pipe 8 is fixedly connected with the sealing ring pad 9 at the end, the sealing ring pad 9 is slidably connected with the water inlet pipe 7, a plurality of grooves 10 are formed in the flow guide pipe 8, a plurality of baffles 11 are fixedly connected with the grooves 10 at the end, the arc-shaped turbulence plate 12 is slidably connected with the baffles 11 inside, and the limiting plate 13 is fixedly connected with the arc-shaped turbulence plate 12 in the middle.

[0034] The rotating assembly includes a support rod 14, a circular ring 15, a rotating handle 16, a pull rod 17, and a hinge ball 18. A plurality of support rods 14 are slidably connected inside the flow guide pipe 8, a plurality of support rods 14 are fixedly connected with the circular ring 15 at the end, the rotating handle 16 is rotatably connected with the circular ring 15 in the middle, the pull rod 17 is rotatably connected with the rotating handle 16 in the middle, and the hinge ball 18 is fixedly connected with the pull rod 17 at the end. The hinge ball 18 is hingedly connected with the limiting plate 13.

[0035] The rotating assembly further includes a retaining rod 19 and a connecting rod 20. The retaining rod 19 is fixedly connected with the circular ring 15 in the middle, and a plurality of connecting rods 20 are fixedly connected with the circular ring 15 in the middle. The connecting rods 20 are clamped with the water inlet pipe 7 at the end.

[0036] The flow guide mechanism includes a ball filter 21, a water pump 22, and a water guide pipe 23. The ball filter 21 is fixedly connected with the water tank 1 inside in the middle, the water pump 22 is fixedly connected with the water tank 1 side, the water guide pipe 23 is fixedly connected with the water pump 22 in the middle, and the water guide pipe 23 is slidably connected with the sealing ring pad 9 at the end.

[0037] The support assembly includes a support rod 2, a protective disc 3, an electric push rod 4, and a circular groove support disc 5. A plurality of support rods 2 are fixedly connected with the water tank 1 in the middle, the support rod 2 is fixedly connected with the protective disc 3 at the end, a plurality of electric push rods 4 are fixedly connected with the protective disc 3 in the middle, the electric push rod 4 is fixedly connected with the circular groove support disc 5 at the end, and the circular groove support disc 5 is slidably connected with the pulse electromagnetic valve body 6.

[0038] When the water flow entering the pulse solenoid valve body 6 needs to be made into a spiral shape, the arc spoiler 12 can be pulled by the rotating assembly, and then the arc spoiler 12 can slide in the groove 10. The arc spoiler 12 and the flow guide pipe 8 can be fixed by the cooperation of the limiting plate 13 and the baffle 11. When the water flow passes through the flow guide pipe 8, the water flow in the flow guide pipe 8 can be rotated by the arc spoiler 12. When the water flow enters the pulse solenoid valve body 6, it becomes a spiral state. When the pulse solenoid valve body 6 is tested, the internal valve can be more comprehensively impacted and detected. When the arc spoiler 12 needs to be pulled out of the groove 10, the circular ring 15 can rotate in the middle of the flow guide pipe 8. At this time, the multiple support rods 14 can support the circular ring 15. Under the pulling action of the pull rod 17, the arc spoiler 12 can slide in the groove 10. At this time, the pull rod 17 can rotate in the middle of the rotating handle 16. By the action of the hinge ball 18, the angle between the pull rod 17 and the arc spoiler 12 can be changed more conveniently when the pull rod 17 pulls the arc spoiler 12. When the circular ring 15 is reversely rotated, the arc spoiler 12 can be pushed into the groove 10 under the action of the pull rod 17, so that the water flow in the flow guide pipe 8 becomes a straight flow state. When the circular ring 15 needs to be rotated, the circular ring 15 and the water inlet pipe 7 can be fixed by the action of the ball filter 21. The fixed rod 19 can connect and fix multiple circular rings 15. At this time, the flow guide pipe 8 can be rotated, so that the flow guide pipe 8 and the circular ring 15 can relatively rotate, and then the arc spoiler 12 can be pulled out of the groove 10. When the water flowing in the flow guide pipe 8 needs to be made into a spiral shape, the rotation of the flow guide pipe 8 can be more quickly realized. When the water needs to be introduced into the flow guide pipe 8, the water pump 22 can be started, and then the water flow in the water tank 1 can be introduced into the pulse solenoid valve body 6 through the water inlet pipe 23. By the action of the ball filter 21, the water in the water tank 1 can be filtered, so that the damage of impurities in the water tank 1 to the pulse solenoid valve body 6 can be reduced. When the pulse solenoid valve body 6 needs to be tested, the pulse solenoid valve body 6 can be placed in the middle of the circular groove support disc 5, and then the pulse solenoid valve body 6 can be supported by the action of the circular groove support disc 5. At this time, multiple electric push rods 4 can be started, so that the height of the pulse solenoid valve body 6 can be adjusted. The protective disc 3 can isolate and protect the pulse solenoid valve body 6 and the water tank 1 when the pulse solenoid valve body 6 is tested, so that the damage of the pulse solenoid valve body 6 can be reduced during the test.

[0039] Further, referring to Figures 1-6The middle of the protection disc 3 is provided with a plurality of sliding grooves 25, and the end of each sliding groove 25 is provided with a clamping groove 26. A round rod 24 is slidably connected in the middle of the clamping groove 26. The end of the round rod 24 is fixedly connected with an extendable drain pipe 27. The extendable drain pipe 27 is slidably connected with the bottom of the pulse electromagnetic valve body 6.

[0040] The bottom of the extendable drain pipe 27 is provided with a plurality of drain grooves 28.

[0041] During operation, after the water flow passing through the inside of the pulse electromagnetic valve body 6 is tested, it can be discharged into the inside of the water tank 1 through the extendable drain pipe 27. When it is necessary to install the extendable drain pipe 27 and the pulse electromagnetic valve body 6, the round rod 24 can be placed in the sliding groove 25, then slid upwardly and placed in the clamping groove 26. Thus, the extendable drain pipe 27 and the pulse electromagnetic valve body 6 can be connected and fixed. Thus, when the pulse electromagnetic valve body 6 is tested, the stability of the connection between the extendable drain pipe 27 and the pulse electromagnetic valve body 6 can be improved. When the water flow in the middle of the pulse electromagnetic valve body 6 is discharged into the inside of the water tank 1 through the extendable drain pipe 27, the extendable drain pipe 27 can be extended to contact the bottom of the water tank 1. Then, through the action of the drain groove 28, the water flow in the extendable drain pipe 27 can be discharged from the side. Thus, when the pulse electromagnetic valve body 6 is tested, the water in the water tank 1 can be prevented from splashing everywhere.

[0042] The detection method of the pulse electromagnetic valve is mainly suitable for the pulse electromagnetic valve testing table. The method mainly includes the following steps:

[0043] S1: First, the pulse electromagnetic valve body 6 to be tested is selected, and then it is fixed at the middle position of the testing table. When placed, the appearance can be checked, and then the working sound is listened to determine whether the valve core is normally attracted;

[0044] S2: After the pulse electromagnetic valve body 6 is fixed, the electrical performance test can be carried out, such as insulation resistance test, voltage resistance performance test and pulse signal verification;

[0045] S3: Finally, the function and air tightness test can be carried out. The repetitive test can be carried out many times to reduce the problems of valve core jamming or reset spring fatigue

[0046] In summary, the durability of the valve can be tested when the pulse electromagnetic valve is tested. The existing detection operation only continuously opens and closes the valve for more than 100 times, and then observes whether the action of the valve is consistent. However, in the use process, the water flow may impact the valve at multiple angles or in multiple styles. The detection method is difficult to comprehensively test the pulse electromagnetic valve.
