Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0020] Reference Figure 1-6 A condenser leak detection instrument includes a detection cylinder 3, an airbag chamber 302 on the detection cylinder 3, an airbag 304 installed on the airbag chamber 302, a first communication port 303 inside the detection cylinder 3, a second communication port 305 inside the detection cylinder 3, a test tube cavity 306 inside the detection cylinder 3 that communicates with and penetrates the second communication port 305, an indicator tube 5 installed inside the test tube cavity 306, a scale 501 marked on the indicator tube 5, a sliding cavity 502 inside the indicator tube 5, a spring 503 fixedly connected inside the indicator tube 5, a sliding plate 504 fixedly connected to the other end of the spring 503, and an inlet / outlet valve 50 at the port of the indicator tube 5. 5. The open end of the indicator tube 5 is connected to the second connecting port 305. The detection head 1 is provided with a detection port 101. An L-shaped buckle 102 is fixedly connected to the detection head 1. A magnet 103 is fixedly connected to the L-shaped buckle 102. A thread 301 is provided on the detection cylinder 3. A connecting sleeve 2 is threaded to the detection cylinder 3. An L-shaped groove 201 is provided on the connecting sleeve 2. A circular groove 202 is provided at the end of the L-shaped groove 201. A magnet 203 is installed in the circular groove 202. A sealing ring 105 is installed on the detection head 1. The L-shaped buckle 102 and the L-shaped groove 201 are used in conjunction with the magnet 103 and the magnet 203.

[0021] When using the device, select the corresponding test head 1 according to the specifications of the condenser being tested, and install the sealing ring 105 on the test head 1. Then install the connecting sleeve 2. When installing the connecting sleeve 2, align the L-shaped buckle 102 fixedly connected on the test head 1 with the L-shaped slot 201 opened on the connecting sleeve 2 and insert and rotate it so that the magnet 103 on the L-shaped buckle 102 and the magnet 203 installed in the circular slot 202 attract and cooperate to make the connection firm. Then install the test cylinder 3. The operator holds the test cylinder 3 and aligns it with the connecting sleeve 2 so that the thread 301 and the thread 204 cooperate to make the test cylinder 3 and the connecting sleeve 2 threadedly connected.

[0022] Then check the airbag 304 for sealing, and check if the red sliding plate 504 installed inside the transparent indicator tube 5 is at the initial scale of the scale 501. Then check if the value on the display screen 4 is normal. After preparation, the operator holds the instrument and places the test port 101 at the port of the condenser to be tested and presses it firmly. Then the operator inflates the condenser from the other end port, allowing air to circulate inside the condenser. At this time, the gas in the condenser will enter the pressure measuring chamber 104 through the circulation. At this time, the airbag 304 installed on the airbag chamber 302 will deform under the influence of pressure, connecting... The sensor 3031 installed in port 303 will feed back data to the display screen 4 and display it. During the deformation of the airbag 304, the air in the airbag 304 will be squeezed into the indicator tube 5 installed in the second connecting port 305 through the second connecting port 305. At this time, the air pressure in the indicator tube 5 will increase, and drive the red sliding plate 504 to compress the spring 503. At this time, the air between the sliding plate 504 and the inlet / outlet valve 505 in the indicator tube 5 will be discharged. At this time, the scale 501 corresponding to the sliding plate 504 in the indicator tube 5 is read. Combined with the data on the display screen 4, double measurement is performed to ensure the accuracy of the measurement.

[0023] The interchangeable detection head 1 can adapt to condensers of different specifications. The two measurement methods are based on different principles, which can avoid measurement failures caused by a single system failure to a certain extent and enhance the reliability of the measurement. In some complex environments, there may be interference with electronic equipment. The two measurement methods can minimize data errors.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
