Description

Technical Field

[0001] This utility model belongs to the field of mechanical equipment and relates to an airtightness testing device, particularly a simple pneumatic brake airtightness testing device. Background Technology

[0002] Pneumatic brakes are brakes that use air pressure to actuate the brakes. Compared to electromagnetic brakes, pneumatic brakes can achieve braking by mechanically filling the brake with air, preventing loss of braking function after power failure.

[0003] However, because pneumatic brakes require air pressure to achieve braking function, they are subject to air tightness requirements. Currently, there is no corresponding testing equipment on the market. The only way to test air tightness is to manually seal the pneumatic brake and inflate it with air. This is time-consuming, labor-intensive, and prone to errors, making it easy to miss unqualified products. Utility Model Content

[0008] In the aforementioned simple pneumatic brake air tightness testing device, a drain valve is provided at the bottom of the booster pump, and a handle is provided on the drain valve.

[0009] In the aforementioned simple pneumatic brake air tightness testing device, the pressure relief valve is equipped with a torsion cap.

[0010] Compared with the prior art, the advantages of this utility model are: by filling the pneumatic brake connected to the detection tube with compressed air to test the air tightness of the pneumatic brake, the detection speed is fast, the air tightness is judged by a pressure gauge to improve the detection accuracy, reduce the energy consumption of the staff when testing products, shorten the detection time, and improve work efficiency.

[0014] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0015] like Figure 1 and Figure 2 As shown, this utility model can be implemented through the following embodiments: A simple pneumatic brake air tightness testing device includes an air inlet pipe 1 and a testing pipe 2. The air inlet pipe 1 is connected to a booster pump 3. A pressure gauge 4 is installed next to the booster pump 3. The booster pump 3 is connected to a ball valve 5. A pressure relief valve 6 is connected to the ball valve 5. A pressure gauge 7 is connected to the pressure relief valve 6. The other end of the pressure gauge 7 is connected to the testing pipe 2.

[0016] The detection tube 2 is used to connect to the pneumatic brake to be tested, and the air inlet tube 1 is used to introduce air; the booster pump 3 is used to compress air to increase atmospheric pressure and to detect the air pressure in the detection tube 2; the ball valve 5 is used to control whether compressed air is input into the detection tube 2; the pressure relief valve 6 is used to release the air pressure in the equipment; the pressure gauge 7 is used to detect the air pressure in the detection tube 2 to ensure that the airtightness test feedback is correct.

[0017] like Figure 1 and Figure 2 As shown, a pressure regulating valve 31 is provided on the top of the booster valve. The pressure regulating valve 31 is used to adjust the target air pressure compressed by the booster pump 3, so as to detect whether the pneumatic brake can achieve the braking function within the specified threshold while detecting the airtightness, and different models of pneumatic brakes can be replaced for testing.

[0018] like Figure 1 and Figure 2 As shown, ball valve 8 is connected between ball valve 5 and pressure relief valve 6. Ball valve 8 is used to isolate the passage between booster pump 3 and detection pipe 2 to ensure that the air pressure in detection pipe 2 is not affected by booster pump 3; at the same time, it is used to detect whether there are any problems in the air passage between ball valve 5 and ball valve 8, as well as between ball valve 8 and detection pipe 2, so as to facilitate quick location of leaks.

[0019] like Figure 2As shown, a drain valve 32 is provided at the bottom of the booster pump 3, and a handle 321 is provided on the drain valve 32. The drain valve 32 is used to remove moisture from the stored air inside the booster pump 3; the handle 321 facilitates manual control.

[0020] like Figure 1 and Figure 2 As shown, the pressure relief valve 6 is equipped with a torsion cap 61. The torsion cap 61 is used by the user to actively relieve pressure, thereby allowing the user to discharge the compressed air in the test tube 2 to the outside, ending the test, and preventing the compressed air from being ejected and causing injury to the worker when disassembling the pneumatic brake under test.

[0021] The working principle of this utility model is as follows: The pneumatic brake to be tested is inserted into the test tube 2, and then air is introduced into the booster pump 3. After the air is compressed by the booster pump 3, the ball valve 5 is opened, so that the compressed air enters the ball valve 8. The ball valve 8 is opened, so that the compressed air passes through the pressure relief valve 6 and the pressure gauge 7, and then enters the pneumatic brake to be tested. After the pointer of the pressure gauge 7 stabilizes, the ball valve 8 is closed, and the reading of the pressure gauge 7 is observed to see if it decreases, thereby testing the airtightness of the pneumatic brake.

[0022] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0023] Although this document uses a variety of terms, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention.
