Description

Technical Field

[0001] The invention belongs to the technical field of leak detection, in particular to a gas leak detection machine. Background Art

[0002] A gas leak detector refers to a machine or equipment that uses detection technology to detect whether there are surface cracks or gaps, thereby achieving airtightness detection of gas leakage problems. For the inspection of automobile transmissions and ventilation ducts, a leak detector is usually used to detect whether there is a risk of leakage on the surface of the structure.

[0003] The gas leakage detection machine in the prior art adopts a gas input method and a blocking method during use. When the open end is sealed, the gas is input into the structure to be tested, and the air pressure is detected to detect whether the ventilation gas pressure is increased to determine the leakage. However, in the actual detection process, the leakage gap is generally very small, and the internal gas leakage is not obvious under low pressure. In addition, for the structure with a large inner cavity, the actual ventilation time is relatively long. During the airtightness detection process, only the leakage judgment is realized. It is difficult to effectively judge the specific leakage location, and usually additional equipment is required for specific positioning detection. The actual detection is difficult and time-consuming, and it is difficult to achieve quick and limited positioning search, and the use effect is not good.

[0004] In addition, during the use of the gas leak detection machine in the prior art, the plugging process of the structure to be tested is affected by the structure of the sealing end. The currently used spiral sleeve sealing method has low adaptability. At the same time, during the plugging process, due to the large structural differences in the open ends of the structures to be tested, the universal ability is weak. At the same time, the plugging effect is general during the plugging and sealing process, and the plugging effect for the heterogeneous opening ends is even worse. When the sealing effect is weak, there is also air leakage at the open end, which affects the final leak detection structure. The actual gas leak detection effect is general and the accuracy is poor.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] like Figures 1 to 10 As shown, an embodiment of the present invention provides a gas leak detection machine, including a base 1, a support frame 2 is fixedly connected to the side of the base 1, an air supply component 6 is fixedly installed on the top of the support frame 2, a spray ring 3 is slidably provided on the top of the base 1, and a spray hole 4 is opened on the inner surface of the spray ring 3, a liquid supply component 5 is provided at one end of the base 1, and the liquid supply component 5 is connected to the spray ring 3, a main air pipe 7 is fixedly connected to the bottom of the air supply component 6, a cover plate 8 is fixedly connected to the bottom end of the main air pipe 7, a liquid pipe 9 is fixedly sleeved inside the cover plate 8, a retaining ring 11 and an annular air bag 12 are respectively provided on the bottom surface of the cover plate 8, a clamping component 13 fixed to the bottom of the cover plate 8 is provided inside the annular air bag 12, a connecting cover 15 is fixedly connected to the top of the cover plate 8, a mounting tube 16 is sleeved on the outer surface of the liquid pipe 9, a switching component 17 is provided inside the mounting tube 16 and the liquid pipe 9, and an intermediate tube 19 is fixedly connected between the mounting tube 16 and the connecting cover 15.

[0032] First embodiment: The object to be tested is placed on the top of the base 1 (may be supported by a support rod, etc., not shown in the figure), the cover plate 8 and the liquid pipe 9 are sleeved on the open end of the object to be tested, the gas supply component 6 is started, so that the gas state is passed into the annular airbag 12, so that the annular airbag 12 expands and blocks the open end of the object to be tested, the external liquid pump connected to the liquid pipe 9 is started, the sodium iodide solution is pumped into the liquid pipe 9, and the sodium iodide is easily passed into the inner cavity of the object to be tested. As the sodium iodide solution is continuously pumped, a small amount of sodium iodide solution penetrates into the gap on the outer surface of the object to be tested, the liquid supply component 5 is started, so that bromine water is injected into the spray ring 3 through the hydraulic pump 52 and the inlet pipe 55, and the spray ring 3 is pushed to move horizontally, so that the spray ring 3 sprays toward the outer surface of the object to be tested through the spray hole 4. As the yellow bromine water is sprayed on the outer surface of the object to be tested, the sodium iodide solution overflowing from the leaking place mixes with the bromine water and turns red. The color change of the surface of the object to be tested is observed to determine the surface leakage position.

[0033] First, by introducing colorless sodium iodide solution and yellow bromine water, after the liquid pipe 9 and the cover plate 8 are sealed with the open end of the test piece, the sodium iodide is directly introduced into the inner cavity of the test piece, and at the same time, the spray ring 3 located outside the test piece is cooperated, and the liquid supply component 5 is used to realize the introduction of bromine water, and at the same time, the outer surface of the test piece is sprayed in cooperation with the moving spray ring 3, so that a layer of yellow bromine water is attached to the outer surface of the test piece. As more and more sodium iodide solution is fed into the test piece, the internal hydraulic pressure is enhanced, and the sodium iodide solution seeps out along the leakage gap of the test piece, and changes color to red when it contacts with the yellow bromine water sprayed on the outer surface. By observing the color change of the outer surface of the test piece, the leakage of the test piece surface is directly obtained, and the leakage point and the leakage amplitude are determined, which greatly improves the detection of the leakage of the device during the actual air tightness detection. The actual leak detection is simple and convenient, and the leak detection result is intuitive and comprehensive, avoiding the detection step of adding leakage points, improving the detection effect, and comprehensively improving the actual detection efficiency, and the use effect is good.

[0034] In addition, by adopting the internal and external feeding of sodium iodide solution and bromine water, combined with the color change characteristics of sodium iodide solution and bromine water, there is no need to use additional sensors to realize leak detection during the leak detection of the test piece, which reduces the cost of sensor investment and avoids increasing the failure rate by adding electronic components. The mechanical structure and liquid are used to comprehensively improve the application performance of the leak detector, with good stability and good use effect.

As the external liquid pump passes the solution into the liquid pipe 9, the liquid enters the mounting hole 18 through the gap 176, and enters the connecting cover 15 along the middle pipe 19, and is distributed to each group of clamping assemblies 13 through the connecting cover 15. The liquid fills the fixed pipe 131 and pushes the push rod 133 in the side pipe 132, so that the surrounding push rods 133 move laterally and clamp in the open end to be tested, and support the cover plate 8 to complete the sealing.

The push rod 133 located in the annular airbag 12 is utilized to deform the annular airbag 12 and clamp and support the opening end of the piece to be tested. At the same time, the subsequent inflation of the annular airbag 12 is cooperated to adapt to the clamping, fixing and sealing of the opening end of the piece to be tested, which greatly improves the application range of the sealing. At the same time, the annular airbag 12 is cooperated to complete the enhanced sealing after the expansion and sealing, and combined with the liquid supply detection, the decrease in leakage detection accuracy caused by lax sealing is greatly reduced, thereby improving the detection effect.

The two ends of the through hole 14 are respectively connected to the annular airbag 12 and the main air pipe 7.

[0042] During use, the clamping assembly 13 is used to adaptively clamp and fix the open end of the test piece, and cooperates with the outer annular airbag 12 to achieve enhanced sealing.

[0044] During use, the switching assembly 17 is installed through the mounting hole 18, and the magnetic rings 178 on both sides are cooperated to ensure that the control rod 174 can maintain stable positioning after sliding back and forth to avoid movement. When the No. 1 hole 172 and the No. 3 hole 175 are connected, the detection supply is realized.
