[0025] like Figure 1-2 As shown, a valve core leakage detection device includes a box body 1 and a cleaning door 2, the cleaning door 2 is movably connected to the front side of the box body 1, and also includes a leakage detection component, which is arranged in the box body 1.

[0026] The air leakage detection component is used to stably position the valve core and efficiently detect air leakage.

[0027] like Figure 1-5 As shown, in order to efficiently detect air leakage of the valve core, the air leakage detection assembly includes a cross plate 3, a clamping block 4, a top plate 5, a linear guide 6, a slider 7, a delivery pump 8 and a nozzle 9. The cross plate 3 is fixedly connected between the inner walls of the box body 1, the clamping block 4 is fixedly connected to the cross plate 3, and they are arranged at equal intervals. The top plate 5 is fixedly connected between the inner walls of the box body 1, the linear guide 6 is fixedly installed at the bottom of the top plate 5, the slider 7 is slidably set on the linear guide 6, the delivery pump 8 is fixedly installed at the bottom of the slider 7, and the nozzle 9 is fixedly connected to the output end of the delivery pump 8.

[0028] By lateral placement of multiple valve cores and lateral position adjustment of the nozzle 9 , efficient detection can be completed.

[0029] like Figure 1-5 As shown, in order to increase the stability of the valve core during the detection process, the leakage detection assembly also includes an electric push rod 10, a connecting plate 11 and a rubber band 12. The electric push rod 10 horizontally passes through one side of the box body 1 and is fixedly connected thereto. The connecting plate 11 is fixedly connected to the free end of the electric push rod 10. The outer wall of the connecting plate 11 is fixedly connected with a protrusion 13, and the protrusions 13 are symmetrically distributed in pairs. The rubber band 12 is fixedly connected between the opposite side walls of the protrusion 13, and the rubber band 12 is respectively arranged on the upper and lower sides of the horizontal plate 3.

[0030] The placement stability of the valve core on the clamping block can be increased by moving the position of the rubber band 12 .

[0031] In order to filter and recycle the used soap water or foam agent, a filter plate 14 is fixedly connected between the inner walls of the box body 1. The bottom of the box body 1 is set with high sides and low middle. A drainage pipe 15 is provided at the bottom of the box body 1.

[0032] Among them, the clamping block 4 is U-shaped, the clamping block 4 is made of elastic material, and there is a gap between the two sides of the clamping block 4 and the horizontal plate 3. An observation window 16 is provided on the front side of the box body 1, and the observation window 16 is made of transparent material. The outer wall of the connecting plate 11 is fixedly connected to a guide rod 17, and one end of the guide rod 17 horizontally passes through the box body 1 and is slidably connected thereto, and the guide rods 17 are symmetrically distributed.

[0033] During specific use, the valve core to be tested is respectively stuck in the corresponding block, and then the electric push rod 10 is controlled to extend, and the connecting plate 11 drives the rubber band 12 to elastically clamp the upper and lower ends of the valve core to increase its stability when placed. The input end of the delivery pump 8 is connected to the box with soapy water or foaming agent outside. When the delivery pump 8 is turned on, the soapy water or foaming agent can be sprayed on the valve core through the nozzle 9, and it can be observed through the observation window 16. The observation window 16 is to prevent soapy water or foaming agent from splashing on the staff. If bubbles emerge from the valve core, it means that the valve core has air leakage. The linear guide 6 is controlled to make the slider 7 slide, and the position of the nozzle 9 can be adjusted to test other valve cores. The filter plate 14 filters the excess soapy water or foaming agent and discharges it through the drain pipe 15 for secondary use, saving resources.
