Description

Technical Field

[0001] This utility model relates to the field of airtightness testing tooling technology, specifically to an airtightness testing device for pneumatic actuators. Background Technology

[0002] Pneumatic actuators are widely used in petroleum, chemical, metallurgical, power, environmental protection, manufacturing and automotive industries. Pneumatic actuators are actuators that use air pressure to open, close or regulate valves. Therefore, the airtightness test of pneumatic actuators is an indispensable part of the production process. Existing pneumatic actuator airtightness test devices mostly use the method of immersing pneumatic actuators. However, after soaking, the pneumatic actuators are not further treated, and the gaskets and metal parts are easily adversely affected, resulting in damage to the function of the pneumatic actuator. Utility Model Content

[0003] To address the shortcomings of existing pneumatic actuator airtightness testing devices that fail to treat pneumatic actuators after water immersion, which can lead to adverse effects on gaskets and metal components and impair the function of the pneumatic actuator, this invention provides a pneumatic actuator airtightness testing device that treats pneumatic actuators after water immersion, preventing damage to gaskets and metal components and ensuring the function of the pneumatic actuator.

[0004] This utility model provides the following technical solution:

[0005] It includes a testing box, which is connected to a water storage tank below it via a supporting water pipe. A vortex pump is installed on one side of the water storage tank. The pump's suction pipe and delivery pipe are respectively connected to the water storage tank and the testing box. A drying box is installed on the back of the testing box. The testing box and the drying box are interconnected, and an isolation plug is provided at the connection point. Drying fans are installed side by side inside the drying box, and positioning columns are installed between the drying fans. The isolation plug is connected to the positioning columns by bolts, thereby disconnecting the testing box and the drying box.

[0006] Its further features are:

[0007] A movable cover is slidably mounted on the top of the testing box, and a slider is snapped onto the end of the movable cover and fixedly connected by bolts;

[0008] The bottom of the testing box is equipped with positioning brackets, which are used to position the pneumatic actuator. A drain valve is provided on the front of the testing box.

[0009] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0010] The setup of the testing chamber, drying chamber, and vortex pump allows the testing chamber to dry the pneumatic actuators after immersion testing, preventing the sealing gaskets and metal parts of the pneumatic actuators from being affected by liquid water, thus ensuring the functionality of the pneumatic actuators.

[0011] The test tank and the water storage tank are connected to a vortex pump to form a closed-loop water flow. The test water will not be used only once and then disposed of, reducing waste and promoting green production for enterprises. Attached Figure Description

[0019] This utility model provides, for example Figure 1 This invention discloses a pneumatic actuator airtightness testing device, comprising a testing chamber 1, which is connected to a water storage tank 2 below it via a supporting water pipe 3. A vortex pump 4 is installed on one side of the water storage tank 2, and the pump's suction pipe and delivery pipe are connected to the water storage tank 2 and the testing chamber 1, respectively. A movable cover 5 is slidably mounted on the top of the testing chamber 1, and a drying chamber 9 is installed on the back of the testing chamber 1. The testing chamber 1 and the drying chamber 9 are interconnected, and an isolation plug 8 is provided at the connection point. Figure 5 Drying fans 11 are installed side by side inside the drying chamber 9, and positioning columns 10 are installed between the drying fans 11. The isolation plug 8 is connected to the positioning columns 10 by bolts, thereby disconnecting the test chamber 1 and the drying chamber 9.

[0020] See Figure 4 The end of the movable box cover 5 is fitted with a slider 6 and is fixedly connected by bolts;

[0021] See Figure 3 The bottom of the test box 1 is equipped with a positioning bracket 12, which is used to position the pneumatic actuator. The front of the test box 1 is equipped with a drain valve 7, which is used to drain the liquid water after the test.

[0022] Working principle of this utility model:

[0023] Refer to the instruction manual appendix Figures 1-5 When using this utility model, first pull the movable cover 5 to fix the pneumatic actuator on the positioning bracket 12. Then turn on the vortex pump 4 and add water from the water tank 2 to the test box 1 until the pneumatic actuator is completely submerged. Carefully observe whether there are bubbles in the pneumatic actuator. If there are, it means that the airtightness is not qualified; otherwise, it is qualified. Then open the drain valve 7, and the liquid water in the test box 1 will flow back into the water tank 2. Then unscrew the bolts to open the isolation plug 8, remove the isolation plug 8, and push the movable cover 5 to put the test box 1 into a closed state. Then open the drying box 9 and the drying fan 11 to dry the inside of the test box 1. After completion, it can be taken out.
