[0001] This utility model relates to the field of four-way valve connecting pipe technology, and in particular to a three-dimensional verification device for four-way valve connecting pipe. Background Technology

[0002] The four-way valve connecting pipe is mainly welded from an inlet straight pipe, a guide bend, and an outlet bend. It is used to connect the four-way valve to refrigeration units such as compressors, gas-liquid separators, and receivers. By changing the refrigerant flow direction, it switches the cooling and heating modes of the air conditioning system. The four-way valve main valve has four connecting pipes, each with different dimensions and complex spatial positions. Deviations can occur during processing and welding, preventing the connecting pipes from being assembled and affecting the connection. Current production processes make verifying the four-way valve connecting pipes cumbersome, requiring multiple measurements of various dimensions, increasing the workload of workers and reducing production efficiency.

[0003] Therefore, this application provides a three-dimensional verification device for a four-way valve connecting pipe to meet the requirements. Utility Model Content

[0007] Preferably, the connecting pipe also includes straight pipes, which are composed of multiple sets of straight pipes, and there is an angle between adjacent straight pipes.

[0008] Preferably, multiple sets of limiting slots are provided and distributed from left to right on the base plate. The depth of the limiting slot is less than the diameter of the four-way valve connecting pipe, the width of the limiting slot is adapted to the four-way valve connecting pipe, and the position of the limiting slot is adapted to the connecting pipe, so as to achieve the effect of inspecting the planar dimensions of the four-way valve connecting pipe.

[0009] Preferably, the slider bracket has a threaded hole, the calibration handle passes through the threaded hole and is connected to a sliding plug gauge, and the calibration handle has a threaded section that matches the threaded hole, so as to verify the spatial dimensions of the four-way valve connecting pipe.

[0010] Preferably, the calibration handle is a T-shaped handle, and a limiting rod is connected to the calibration handle to limit the vertical movement distance of the calibration handle. The limiting rod is located above the threaded section, so that the vertical movement stroke of the calibration handle is limited.

[0011] In summary, the technical effects and advantages of this utility model are as follows:

Example

[0021] refer to Figure 1-4 The illustrated three-dimensional calibration device for a four-way valve connecting pipe includes a base plate 1 and a four-way valve connecting pipe 7. The four-way valve connecting pipe 7 also includes a vent copper straight pipe 71. The vent copper straight pipe 71 is connected to a connecting pipe 74 via a vent steel bend 72. The other end of the connecting pipe 74 is connected to an outlet copper bend 73. A reference plug gauge 6 for fixing the four-way valve connecting pipe 7 is provided at the front end of the base plate 1. The reference plug gauge 6 is adapted to the vent copper straight pipe 71. A slider bracket 2 is also provided at the rear end of the base plate 1. A sliding plug gauge 4 is connected to the slider bracket 2 via a calibration handle 5. The sliding plug gauge 4 is adapted to the outlet copper bend 73. Through the reference plug gauge 6 and the sliding plug gauge 4, the device can calibrate the pipe opening size of the four-way valve connecting pipe 7.

[0022] As one embodiment of this invention, in order to enable the device to inspect the planar dimensions of the four-way valve connecting pipe 7, a limit slot 3 is also installed on the base plate 1. There are three sets of limit slots 3, which are installed sequentially from front to back on the base plate 1 between the reference plug gauge 6 and the sliding plug gauge 4. The three sets of limit slots 3 are staggered, and the planar dimensions of the four-way valve connecting pipe 7 are inspected using the dedicated limit slots 3.

[0023] As one implementation method in this embodiment, in order to verify the spatial dimensions of the four-way valve connecting pipe 7, the slider bracket 2 is provided with a threaded hole, the calibration handle 5 is provided with a threaded section, and the calibration handle 5 above the threaded section is provided with a limiting rod 51 for limiting the calibration handle 5. The calibration handle 5 is engaged in the threaded hole on the slider bracket 2. By rotating the calibration handle 5, the height of the sliding plug gauge 4 is adjusted, so that the equipment can achieve the effect of verifying the spatial dimensions of the four-way valve connecting pipe 7.

[0024] The working principle of this utility model is as follows: First, place the vent copper straight pipe 71 of the four-way valve connecting pipe 7 on the reference plug gauge 6. Use the reference plug gauge 6 to verify the pipe opening size of the vent copper straight pipe 71. Then, place the connecting pipe 74 of the four-way valve connecting pipe 7 in the limiting groove 3. Use the dedicated limiting groove 3 to check the planar dimensions of the connecting pipe 74. Next, connect the outlet copper elbow 73 to the sliding plug gauge 4. When the sliding plug gauge 4 is located inside the outlet copper elbow 73, the pipe opening size of the outlet copper elbow 73 can be checked simultaneously with the three-dimensional spatial angle. When both ends of the four-way valve connecting pipe 7 are fixed on the reference plug gauge 6 and the sliding plug gauge 4 respectively, the connecting pipe 74 is simultaneously located within the three sets of limiting grooves 3. Then, rotate the calibration handle 5. The calibration handle 5 moves downward in the slider bracket 2, causing the sliding plug gauge 4 to move downward, thereby verifying the assembly dimensions and three-dimensional spatial angles of the four-way valve connecting pipe 7.
