Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning stop valve calibration devices, in particular to an air-conditioning stop valve copper pipe opening inner and outer diameter calibration device. Background Art

[0002] The air conditioning stop valve is an important component of the split air conditioner. By operating the valve stem, the internal passage of the valve can be closed, which plays the role of connecting the outdoor unit and the indoor unit, closing or opening the refrigerant circuit. The copper tube welded at the welding end of the air conditioning stop valve is an important part of the air conditioning system. It is an important carrier for connecting and transmitting refrigerant to ensure the normal operation of the air conditioning system. During the production and processing of the air conditioning stop valve, the inner and outer diameters of the copper tube need to be calibrated during production in the copper tube workshop, welding workshop and assembly workshop. The purpose of this is to ensure that when the finished air conditioning stop valve is delivered to the user, the user's piping can be more conveniently connected to the copper tube on the air conditioning stop valve, thereby improving user satisfaction. At present, two sets of calibration devices are required to calibrate the inner and outer diameters of the copper tube in the copper tube workshop, welding workshop and assembly workshop. One staff member takes a set of inner diameter calibration devices to calibrate the inner diameter of the copper tube, and the other staff member takes a set of outer diameter calibration devices to calibrate the outer diameter of the copper tube. In this way, two staff members are required to calibrate the inner and outer diameters of the copper tube, and the calibration time required is relatively long. Therefore, it is necessary to provide a solution to reduce the correction cost and improve the correction efficiency. Summary of the invention

[0026] The utility model is further described below in conjunction with the accompanying drawings:

[0027] The air conditioning stop valve is divided into two-way air conditioning stop valve and three-way air conditioning stop valve. Figure 6 and Figure 7 As shown, the structure of the two-way air-conditioning stop valve includes a valve cap end 21, a pipe nut end 22 and a welding end 24, and a mounting plate 23 is provided on the outer side of the air-conditioning stop valve 2 near the welding end 24, wherein the welding end 24 is plugged with a copper tube 3, and the end of the copper tube 3 away from the air-conditioning stop valve 2 is a pipe opening 31.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model provides an inner and outer diameter correction device for the copper tube orifice of an air-conditioning stop valve, comprising a correction device body 1. A first correction part 11 for correcting the inner diameter of the orifice 31 of the copper tube 3 is provided near one end of the correction device body 1, and the first correction part 11 is cylindrical. A second correction part 12 for correcting the outer diameter of the orifice 31 of the copper tube 3 is provided outside the correction device body 1, and the second correction part 12 is cylindrical groove-shaped. The central axis of the first correction part 11 coincides with the central axis of the second correction part 12. The first correction part 11 extends to the outside of the end of the correction device body 1, so that the inner diameter of the orifice 31 of the copper tube 3 can be corrected first. If the outer diameter of the orifice 31 of the copper tube 3 is corrected first, the correction device will block the orifice 31. When the correction device subsequently corrects the inner diameter of the orifice 31 of the copper tube 3, the staff will not be able to observe the specific correction of the inner diameter, which is inconvenient to correct the inner diameter of the orifice 31 of the copper tube 3. The diameter size of the first correction part 11 is 2.8-3.0 mm. The diameter of the second correction part 12 is 6.25-6.45 mm. The depth of the second correction part 12 is 16-30 mm. In this embodiment, the diameter of the first correction part 11 is 2.9 mm, the diameter of the second correction part 12 is 6.35 mm, and the depth of the second correction part 12 is 20 mm.

[0029] like Figure 2 and Figure 3As shown, on the basis of the above embodiment, further, the first correction part 11 is provided with a first arc portion 111 at one end away from the correction device body 1. The second correction part 12 is provided with a second arc portion 121 near the end of the correction device body 1. The first arc portion 111 and the second arc portion 121 can prevent the correction device from causing scratches when contacting with the pipe mouth 31 of the copper tube 3 on the air conditioning stop valve 2 for correction.

[0030] like Figure 2 and Figure 3 As shown, on the basis of the above embodiments, further, the first correction part 11, the second correction part 12 and the correction device body 1 are formed by one-piece processing, and the one-piece processing can ensure the accuracy of the correction device.

[0031] like Figure 1 As shown, based on the above embodiment, further, the calibration device body 1 is cylindrical or a regular quadrangular prism or a regular hexagonal prism. In this embodiment, the calibration device body 1 is cylindrical. The calibration device body 1 can also be designed into other shapes that are convenient for users to hold.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, during operation, first, a staff member holds the correction device body 1 in one hand and takes an air-conditioning stop valve 2 to be corrected in the other hand, then, the staff member aligns the first correction part 11 on the correction device body 1 with the pipe mouth 31 of the copper tube 3 on the air-conditioning stop valve 2, then, the staff member pushes the correction device body 1 so that the first correction part 11 is inserted into the pipe mouth 31 to correct the inner diameter of the pipe mouth 31, then, the staff member continues to push the correction device body 1 so that the pipe mouth 31 enters the second correction part 12, and the second correction part 12 corrects the outer diameter of the pipe mouth 31, finally, the staff member pulls the correction device body 1 out of the pipe mouth 31, and completes a correction process for the pipe mouth 31 of the copper tube 3 on an air-conditioning stop valve 2.

[0033] The above are only preferred embodiments of the present invention, and do not limit the scope of the present invention. A person skilled in the art should understand that various changes, modifications, substitutions and deformations can be made to these embodiments without departing from the principles and purposes of the present invention, which should all be included in the scope of protection of the present invention. The scope of protection of the present invention is defined by the claims and their equivalents.
