And an air inlet channel is arranged in the center of the plug.

After the ICV valve is sleeved in the sealing tank, one end of the ICV valve is sealed by a product sealing ring arranged on the ICV valve and the inner wall of the sealing tank.

According to the technical scheme of the utility model, when airtight detection, the operator packs the ICV valve into the seal tank body, puts it on the U-shaped seat for positioning, then starts the plugging cylinder, and the end cap on the output shaft of the plugging cylinder extrudes and clamps the seal tank, and the sealing ring is matched to make the product in a sealed environment, and the sealed tank is inflated through the air inlet channel of the end cap, airtight detection is carried out, and judgment is made, and after the airtight detection is finished, the plugging cylinder loosens the end cap to remove the gas in the air tank;

when opening force detection is carried out, the ICV valve is required to be arranged in a sealing tank body and is placed on a U-shaped seat for positioning, then a plugging cylinder is started, a plug on an output shaft of the plugging cylinder extrudes and clamps the sealing tank, then a guide motor is started, an output shaft of the guide motor rotates to drive a movable seat to move towards one side of a sensor, when a valve core of a product is in contact with a pressure probe extending into the sealing tank, pressure and displacement can be recorded, judgment is made, after the judgment is finished, the movable seat returns to an original position, and the plugging cylinder loosens the sealing tank.

This equipment has accomplished the detection to the leakproofness of ICV valve, opening force simultaneously, compares with traditional detection mode, and efficiency is higher, detection effect is better. Through statistics, the ICV valve is detected by using the device, so that 90% of detection time can be saved, and the working efficiency is greatly improved. Therefore, the utility model discloses detection efficiency is high, the detection accuracy is high, can realize the invention purpose of online full examination function completely realized.
