Description

Technical Field

[0001] The utility model relates to the technical field of helium detection, in particular to a helium detection sealing device. Background Art

[0002] Helium seal detection is a commonly used method for detecting leaks. It is used to detect tiny leaks in boxes, tanks, pipes and other items to detect the seals of containers and pipes to ensure the equipment's waterproof, dustproof, and gas leakage-proof properties. When detecting leaks, soap solution is usually applied to the outer surface of the object to be tested to make the gas sprayed from the leak point blow out bubbles. However, applying soap solution in this way is very cumbersome and easy to miss, resulting in the inability to detect all leaks, which is very energy-consuming for workers. Utility Model Content

[0003] The utility model aims to provide a helium detection sealing device to solve the problem that the application of soap solution is cumbersome and easy to leak in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a helium detection sealing device, comprising an outer frame, a conical platform is fixedly installed on the outer surface of the outer frame, and the conical platform protrudes from the outer surface of the outer frame, a sealing gasket is fixedly installed inside the outer frame, and the side surface of the sealing gasket is in contact with the outer surface of the outer frame, an upper frame is arranged on the side of the outer frame close to the conical platform, and the upper frame is a box made of transparent material, and one end of the upper frame is tightly fitted with the outer surface of the sealing gasket, and a circulating extraction mechanism is arranged between the upper frame and the outer frame, and the soap solution can be recycled through the circulating extraction mechanism to conveniently spray the seal to be tested.

[0005] Preferably, the circulating extraction mechanism includes: a liquid suction pump, which is fixedly installed on the outer surface of the upper frame, and an atomizing nozzle is fixedly installed inside the upper frame, the input end of the atomizing nozzle is connected to the output end of the liquid suction pump, and the input end of the liquid suction pump passes through the outer surface of the upper frame, and a liquid suction pipe is fixedly installed on the inner side of the upper frame, and the liquid suction pipe is connected to the input end of the liquid suction pump.

[0006] By adopting the above technical scheme, the soap solution poured into the outer frame can be sucked into the suction pump through the suction tube, and sprayed to the detection tank body inserted on the upper end of the conical table through the atomizing nozzle, so that the outer surface of the detection tank body is evenly sprayed with the soap solution, and helium is injected into the detection tank body to check whether bubbles emerge, thereby eliminating the tedious process of applying the soap solution, and at the same time, the surface of the tank body can be continuously moistened, and the sprayed soap solution can be sucked back for reuse.

[0007] Preferably, a helium tank is installed in a plug-in manner on the side surface of the outer frame, and the helium tank passes through the side surface of the outer frame, an air pressure valve is fixedly installed on the side surface of the outer frame, and one end of the air pressure valve is connected to the helium tank, an electromagnetic valve is fixedly installed between the helium tank and the air pressure valve, an insertion port is installed in a plug-in manner on the outer surface of the conical table, and the plug-in port is connected to the air pressure valve, and a piece to be tested is installed in a plug-in manner on one end of the plug-in port located inside the upper frame.

[0008] By adopting the above technical solution, the tank to be tested can be fixed on the outer surface of the conical table through the plug interface, and the amount of air injected into the helium tank can be controlled by the solenoid valve to maintain the pressure in the test tank, and whether the tank is leaking can be judged by observing the air pressure valve.

[0009] Preferably, a sliding mechanism is provided between the outer frame and the upper frame, and the upper frame is lifted by the sliding mechanism to facilitate the removal of the tested object, and at the same time, the outer frame and the upper frame can be tightly fitted to maintain a seal.

[0010] By adopting the above technical solution, the outer frame and the upper frame can be easily separated, and the items on the plug-in interface can be removed. At the same time, the outer frame and the upper frame can clamp the sealing gasket to ensure the sealing between the outer frame and the upper frame.

[0011] Preferably, the sliding mechanism includes: a sliding support rod, the sliding support rod is fixedly mounted on both sides of the outer frame, a sliding block is fixedly mounted on the outer surface of one end of the upper frame away from the conical table, and the outer surface of the sliding block is penetrated by the sliding support rod, an electric push rod is fixedly mounted on the end of the sliding support rod away from the outer frame, and the output end of the electric push rod is connected to the sliding block, and the outer surface of the upper frame is in contact with the inner surface of the outer frame.

[0012] By adopting the above technical solution, the upper frame can be pushed out by the sliding block driven by the electric push rod, so that the sliding block moves along the direction of the sliding support rod, so that the upper frame squeezes the sealing gasket, so that the sealing gasket is clamped by the frame and the outer frame to maintain the sealing between the outer frame and the upper frame.

[0013] Preferably, a pipeline mechanism is provided between the outer frame and the conical platform, and the extraction and pressure relief of the gas in the upper frame can be controlled through the pipeline mechanism, so that the sealing of the test piece can be measured more quickly.

[0015] Preferably, the pipeline mechanism includes: an air inlet pipe, which passes through the outer surface of the conical table, a helium recovery machine is fixedly installed on the side surface of one end of the outer frame, and a vacuum pump is arranged between the helium recovery machine and the outer frame, and the input end of the vacuum pump passes through the outer surface of the conical table, the output end of the vacuum pump is connected to the helium recovery machine, and the end of the vacuum pump located inside the conical table is designed to be horizontal.

[0016] By adopting the above technical solution, the gas in the upper frame can be quickly extracted by the vacuum pump to form a vacuum state. When it is necessary to restore the normal pressure in the upper frame, it is only necessary to open the air inlet pipe and cooperate with the vacuum pump to extract the helium leaked in the upper frame, and then the helium can be sucked into the helium recovery machine for recovery.

[0017] Compared with the prior art, the utility model has the following beneficial effects: the helium detection sealing device:

[0018] 1. Connect the tank to be tested to the plug-in interface and close the upper frame, then start the suction pump, so that the soap liquid inside the outer frame is sucked into the suction pump through the suction pipe and pumped out to the atomizing nozzle. The atomized soap liquid is evenly sprayed on the outer surface of the tank through the atomizing nozzle. At the same time, the falling soap liquid returns to the groove of the outer frame and the cone table for recirculation, which reduces the time of applying the soap liquid, improves efficiency, and reduces the probability of missing brushing;

[0019] 2. After the tank to be tested is installed, the electric push rod can be started to push out the sliding block, so that the sliding block pushes out the upper frame along the sliding support rod, so that the upper frame squeezes the sealing gasket, so that the sealing gasket fits tightly with the outer frame and the upper frame to maintain the sealing of the outer frame and the upper frame. At the same time, the soap liquid can be observed during vacuuming to determine whether there is leakage between the outer frame and the upper frame. After the inspection is completed, the electric push rod is contracted to drive the sliding block to separate the outer frame from the upper frame to facilitate the removal of the tank, so that the tested tank can be easily removed, while ensuring the sealing between the outer frame and the upper frame;

[0020] 3. After the tank is coated with soap solution, the vacuum pump can be started to evacuate the upper frame and inject helium into the tank to be tested. The negative pressure in the upper frame and the positive pressure in the tank make it easier for the helium to be discharged from the leaking point of the tank. Observe whether the pressure valve pointer changes and whether bubbles are generated on the surface of the tank to quickly determine whether there is a leak in the tank. When the test is completed, the upper frame can be depressurized by opening the air inlet pipe. Then, the leaked helium can be pumped into the helium recovery machine for recycling by starting the vacuum pump. This makes it easy to determine which tank is leaking and can also recover the leaked helium. BRIEF DESCRIPTION OF THE DRAWINGS
