When the main body 8 leaks, the first eardrum 13 has elasticity, so that when the gas on the inner wall of the main body 8 leaks, the gas pushes the first eardrum 13 to drive the electromagnetic sheet 16 to move and fit with the electromagnetic sheet 16 at the bottom of the second eardrum 14. When the main body 8 leaks and the sealing is insufficient, it can be warned in time, and the warning light 5 is used to warn personnel, so that personnel can check the main body 8 in time to confirm the condition of the vacuum valve, thereby improving the practicality of the device. The main body 8 is clamped by two stabilizing plates 7, and the spring 12 is compressed by the stabilizing plate 7 through the round rod 11, so that the round rod 11 forms a sliding sleeve on the inner wall of the short rod 10, which increases the stability of the main body 8 and avoids the displacement of the main body 8 during operation.
