Description

Technical Field

[0001] The utility model relates to the technical field of mufflers, and particularly relates to a resistance test tooling for a gas muffler. Background Art

[0002] In the modern industrial field, especially in industries such as mechanical manufacturing, automobile manufacturing, and aerospace, as a key component for reducing noise pollution, the performance of a gas muffler directly affects the overall operating efficiency of the equipment and the environmental quality. Among them, the resistance characteristic of the gas muffler is one of the important indicators to measure its performance. Excessive resistance will not only increase the energy consumption of the power system but also may affect the normal operation and service life of the equipment.

[0003] However, the traditional gas muffler resistance test methods often have many deficiencies. For example, the test equipment has a complex structure and cumbersome operation, resulting in low test efficiency; the test accuracy is greatly affected by environmental factors, making it difficult to ensure the accuracy and reliability of the test results; in addition, the traditional test tooling usually lacks flexibility and versatility and is difficult to meet the test requirements of different types and specifications of gas mufflers.

[0025] The following combines specific embodiments to further elaborate on the content of the present utility model:

[0026] As Figures 1-4 shown, a resistance test tooling for a gas silencer includes a first housing 1 and a second housing 2. The outer side surface of the first housing 1 is provided with an inlet pipe 6 and an outlet pipe 7. The first housing 1 is connected to the second housing 2 through a quick-release buckle 3, so as to form an accommodating space 4 between the first housing 1 and the second housing 2. A gas silencer 5 and a connecting pipe 8 are installed in the accommodating space 4. The position of the connecting pipe 8 corresponds to that of the inlet pipe 6, and both ends of the connecting pipe 8 are respectively communicated with the inlet pipe 6 and the gas silencer 5. When the first housing 1 and the second housing 2 are buckled through the quick-release buckle 3, the gas enters the gas silencer 5 through the inlet pipe 6 and the connecting pipe 8 for silencing, then enters the accommodating space 4, and finally is discharged through the outlet pipe 7. Because there is only one air outlet channel, the gas can only be discharged along one position, which is convenient for gas collection, and reduces the complexity and uncertainty that may be brought by multiple channels. During the test, multiple channels may interfere with each other when collecting gas, such as the mutual influence between airflows and pressure fluctuations. These interference factors may affect the accuracy of the test results. Reducing the number of channels helps to reduce the influence of multiple channels on the result accuracy and improve the test precision.

[0027] As a further explanation, the inlet pipe 6 and the outlet pipe 7 can also be arranged on the outer side surface of the second housing 2. The inlet pipe 6 is communicated with the gas silencer 5 through the connecting pipe 8, so that the gas can pass through the gas silencer 5 and is discharged only from one outlet pipe 7, thereby facilitating other collections and accurately measuring the flow loss.

[0028] In one embodiment, a plurality of fixing plates 9 are fixedly arranged in the accommodation space 4. The fixing plates 9 are fixed in the first housing 1. A limiting hole 91 is arranged on the fixing plate 9, and the inner wall surface of the limiting hole 91 matches the outer wall surface shape of the gas silencer 5. The gas silencer 5 is snap-fitted in the limiting hole 91, so that the gas silencer 5 can be firmly fixed in the limiting hole 91, preventing it from shifting or falling off under complex working conditions, thereby enhancing the stability of the entire silencing system. To a certain extent, it can also reduce the swaying of the gas silencer 5 caused by air flow impact or mechanical vibration, which is beneficial to protecting the gas silencer 5 from damage and extending its service life. Among them, the fixing plate 9 protrudes relative to the side wall of the first housing 1, and the protruding position is provided with a chamfer, so that the first housing 1 and the second housing 2 can be assembled more smoothly, reducing the assembly difficulty and time and improving the assembly efficiency.

[0029] In another embodiment, the fixing plate 9 is fixed in the second housing 2. When the first housing 1 and the second housing 2 are buckled with each other, the gas silencer 5 is fixed in the limiting hole 91 to prevent it from loosening due to vibration or external force during operation. And the fixing plate 9 protrudes relative to the side wall of the second housing 2, and the protruding position is provided with a chamfer.

[0030] Furthermore, as Figures 5-6 shown, the quick-release buckle 3 includes a fixed end 32 and a mobile end 31. First ribs 10 and second ribs 11 are respectively arranged on the inner walls of the first housing 1 and the second housing 2. The positions of the plurality of first ribs 10 correspond to the position of the mobile end 31, and the positions of the plurality of second ribs 11 correspond to the fixed end 32. The mobile end 31 and the fixed end 32 are respectively installed on the first housing 1 and the second housing 2 through screws, and the screws penetrate through the first housing 1 and the second housing 2 and are fixed on the first ribs 10 and the second ribs 11, so that there is no gap in the connection between the quick-release buckle 3 and the first housing 1 and the second housing 2, improving the airtightness between the housings and preventing gas leakage from affecting the test of flow loss.

[0031] To reduce the influence of vibration on the test results when the gas silencer 5 is in use, the first ribs 10 and the second ribs 11 protrude relative to the inner walls of the corresponding first housing 1 and the second housing 2. When the first housing 1 and the second housing 2 are buckled, the second rib 11 is inserted between the two first ribs 10, forming a mutually nested structure, making the cooperation between the first housing 1 and the second housing 2 tighter, effectively preventing relative movement or misalignment between the housings, thereby enhancing the stability of the overall structure and reducing the influence brought by vibration. After the second rib 11 is inserted between the first ribs 10, the gap between them is effectively reduced, which helps to improve the sealing performance between the housings.

[0032] To improve the airtightness between the first housing 1 and the second housing 2, two contact surfaces of the first housing 1 and the second housing 2 are respectively provided with a recess 12 and a protrusion 13, which are arranged along the contours of the corresponding first housing 1 and second housing 2. The recess 12 matches the protrusion 13, and a sealing ring is provided between the recess 12 and the protrusion 13 when the first housing 1 and the second housing 2 are buckled. The sealing ring can be closely attached between the recess 12 and the protrusion 13, effectively preventing leakage of substances such as gas, improving the overall sealing performance, and in a vibration or impact environment, the sealing ring can play a certain buffering role, reducing the impact of vibration on the housing.

[0033] The implementation principle of this embodiment:

[0034] When performing the resistance test on the gas silencer 5, the gas silencer 5 is fixed in the limit hole 91 on the fixed plate 9, and the air inlet of the gas silencer 5 is connected to the connecting pipe 8. Subsequently, the quick-release buckle 3 is buckled. At this time, the second rib 11 is inserted into the two first ribs 10, and the protrusion 13 and the recess 12 also match each other, increasing the airtightness and stability of the first housing 1 and the second housing 2, preventing gas leakage or vibration from affecting the test. The gas enters the gas silencer 5 through the inlet pipe 6 and the connecting pipe 8, and then the gas enters the accommodation space 4 through the gas silencer 5 and is discharged only through one outlet pipe 7, facilitating the collection of gas, and measuring the flow loss according to the flow rates of the inlet and outlet gases.

[0035] The above embodiments are only for explaining the technical concept and characteristics of the present invention, and their purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it accordingly, and cannot be used to limit the protection scope of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-limiting.

Therefore, it is intended to include all changes falling within the meaning and scope of the equivalent elements of the claims in the present invention.
