[0002] Valves are mainly used to block the flow of media in pipes and usually need to have high sealing performance.

[0003] The existing detection method mainly uses the air blowing pressure measurement method, which is achieved by blowing in standard pressure gas and then detecting its pressure movement. However, due to the extremely small sealing gap between some rubber rings and valve baffles, the gas pressure fluctuation is not obvious during the faster factory detection time, resulting in the inability to accurately detect whether there is a gap, causing unqualified products to flow out. Summary of the invention

[0004] In order to solve the above problems existing in the prior art, the present invention aims to provide an automatic valve line sealing test device which has a fast speed and can effectively detect the fine sealing gap of the valve.

Lifting push rods are provided at both ends of the lifting block, and both ends of the lifting push rods are slidably connected to the beveled edges of the beveled push plates on the adjacent clips.

[0010] In one embodiment, the sliding cross bar is also provided with a leakage indicating mechanism, and the leakage indicating mechanism includes a liquid barrel, which is arranged in the middle of the other end of the valve to be inspected away from the detection mechanism, and a plurality of liquid spraying ports are arranged on the liquid barrel. The inner cavity of the liquid barrel is provided with a liquid pushing plug, one end of the liquid pushing plug passes through and is slidably connected to the inner cavity of the liquid barrel, and the other end of the liquid pushing plug passes through and is slidably connected to the sliding cross bar.

[0011] In one embodiment, a touch plate is further provided in the middle of the liquid pushing plug, and when the lifting push rod moves away from the bevel push plate, it touches the touch plate and then pushes the liquid pushing plug to squeeze the liquid in the liquid barrel.

[0017] After the operator first starts the lifting rod to adjust the height, the first rotating motor and the second rotating motor rotate in the same direction, and the fixing mechanism on the first rotating disk of Da Ai moves to the top of the valve to be inspected on the conveyor belt. After the lifting rod continues to descend and drives the arc plate in the dial rod to fall into the inner cavity of the valve to be inspected, the second rotating motor is rotated to drive the second rotating disk to rotate, and the guide rod is guided by the transverse groove to the first inclined groove, so that the clamp is away from the suspension rod. In the process of the clamp moving away from the suspension rod, the lifting push rod pushes the bevel push plate to make the clamps on both sides move away from each other, and further drives the dial rods under the resistance block on the sliding block to move away from each other, clamping the valve to be inspected below. Since the outer side of the valve to be inspected is usually irregular, clamping the inner wall of the valve to be inspected can effectively improve the adaptability of clamping and lifting of different valves to be inspected. At the same time, since the resistance block is guided by the sliding guide block in the guide groove, it can slide on the outside of the expansion block, and change the spacing between the dial rods on the two sets of resistance blocks while sliding, so as to better match valves to be inspected with different pipe diameters.

[0018] After the buckle is completed, the first rotating motor and the second rotating motor continue to rotate at the same time, and after driving the valve to be inspected to fall above the detection mechanism, the lifting rod is driven to drop the valve to be inspected above the fitting barrel, and the inspection is started by tightly fitting the valve to be inspected through the telescopic rod, and the air in the fitting barrel is sucked away through the air suction hole. During the air suction process, the wind chime swings and makes a sound. Since the wind chime is usually connected by a silk thread, there is almost no indirect contact with the vibration medium. Until the inside of the fitting barrel is vacuumed, the sound of the wind chime inside the fitting barrel cannot be transmitted through the vacuum cavity, so it can be judged whether the valve to be inspected is sealed. Any tiny gap will emit the sound of the wind chime, so it can be judged whether it is sealed. If there is a sound, the second rotating motor is rotated to drive the guide rod to flow from the first inclined groove into the second inclined groove, so that the lifting push rod pushes the touch plate to push the liquid plug to push the liquid in the liquid filling barrel through the liquid spray port to the edge of the valve to be inspected. This time, wax liquid is preferably used. Under the action of the air suction hole, the valve to be inspected is sealed to complete the inspection.

[0019] The device has a simple structure and uses the property that sound is not easily transmitted in a vacuum to quickly detect tiny gaps in the valve to be inspected. At the same time, it can adapt to valves to be inspected with different diameters and accurately locate the gaps. It has good practicality and economy, and is beneficial to the promotion and use of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

Wax liquid is preferably used this time, and the valve to be inspected 2 is sealed under the action of suction through the exhaust hole 33.

[0038] Working principle of the present invention:

[0039] After the operator starts the lifting rod 62 to adjust the height, the first rotating motor 64 and the second rotating motor 641 rotate in the same direction, and the fixing mechanism 4 on the first rotating disk 642 of Da Ai moves to the top of the valve 2 to be inspected on the conveyor belt 1. After the lifting rod 62 continues to descend and drives the arc plate in the connecting rod 441 to fall into the inner cavity of the valve 2 to be inspected, the second rotating motor 641 is rotated to drive the second rotating disk 643 to rotate, and the guide rod 661 is guided by the transverse groove 6431 to the first inclined groove 6432, so that the clamp is away from the hanging rod 65. In the process of the clamp moving away from the hanging rod 65, the lifting push rod 42 pushes The beveled push plate 43 makes the clamps on both sides move away from each other, further driving the connecting rod 441 below the resistance block 44 on the sliding block 431 to move away from each other, clamping the valve 2 to be inspected below. Since the outer side of the valve 2 to be inspected is usually irregular, clamping the inner wall of the valve 2 to be inspected can effectively improve the adaptability of clamping and lifting of different valves 2 to be inspected. At the same time, since the resistance block 44 is guided by the sliding guide block 442 in the guide groove 433, it can slide on the outside of the expansion block 432, and change the distance between the connecting rods 441 on the two groups of resistance blocks 44 while sliding, so as to better match the valves 2 to be inspected with different pipe diameters.

[0040] After the buckling is completed, the first rotary motor 64 and the second rotary motor 641 continue to rotate simultaneously, driving the valve 2 to be inspected to fall above the detection mechanism 3, and then driving the lifting rod 62 to drop the valve 2 to be inspected above the fitting barrel 31, and then the valve 2 to be inspected is tightly fitted with the telescopic rod 34 to start the inspection, and the air in the fitting barrel 31 is sucked away through the suction hole 33. During the suction process, the wind chime 312 swings and makes a sound. Since the wind chime 312 is usually connected by a silk thread, there is almost no indirect contact with the vibration medium. Until the inside of the fitting barrel 31 is vacuumed, the sound of the wind chime 312 inside the fitting barrel 31 cannot be heard. By propagating in the vacuum cavity, it can be determined whether the valve 2 to be inspected is sealed. Any tiny gap will emit the sound of the wind chime 312, so as to determine whether it is sealed. If there is sound, the second rotating motor 641 is rotated to drive the guide rod 661 to flow from the first inclined groove 6432 into the second inclined groove 6433, so that the lifting push rod 42 pushes the touch plate 521 to push the liquid push plug 52 to push the liquid in the liquid filling barrel 51 through the liquid spray port 512 to flow into the edge of the valve 2 to be inspected. Wax liquid is preferably used this time. Under the action of suction through the air suction hole 33, the valve 2 to be inspected is sealed to complete the inspection.
