Description

Technical Field

[0001] This utility model relates to the technical field of four-way valve production equipment, and in particular to a water blowing device for the production of four-way valves. Background Technology

[0002] Four-way valves are mainly used in air conditioning systems to switch the refrigerant flow path, thereby enabling the entire system to perform cooling, heating, and defrosting functions. Figure 7 and Figure 8 As shown, the four-way valve 3 includes a main valve 31, a pilot valve 35, and a solenoid coil. The pilot valve 35 is fixed to one side of the main valve 31 by a bracket 36. The solenoid coil is fixed to the pilot valve 35 by screws. A connecting pipe 34 is also fixedly welded to the side of the main valve 31. A first end cap 32 and a second end cap 33 are fixedly installed at both ends of the main valve 31, respectively. Currently, the first end cap 32 and the second end cap 33 at both ends of the main valve 31 are welded by high-frequency welding. After welding, they need to be cooled by rinsing with cooling water. The problem that exists in the specific welding process is, for example, the main valve 31 and the first end cover 32 are welded first, and then cooled by rinsing with cooling water. Then the main valve 31 is rotated 180° and the main valve 31 and the second end cover 33 are welded. However, the cooling water is not cleaned in any way, and cooling water is easy to remain at the position of the second end cover 33. When the main valve 31 and the second end cover 33 are welded, the cooling water will evaporate, resulting in insufficient depth of solder flow. Pores will be generated between the main valve 31 and the second end cover 33, which will eventually lead to the quality problem of leakage in the finished four-way valve 3. Summary of the Invention

[0003] The purpose of this invention is to provide a water blowing device for the production of four-way valves in order to solve the above-mentioned problems.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] A water blowing device for the production of four-way valves includes a frame, on which an air blowing nozzle is fixedly mounted. A placement rack for placing the four-way valve is fixedly mounted on the top of the frame. The placement rack is a C-shaped cylinder with an open groove on one side. The placement rack covers the air blowing nozzle. Air is supplied to the air blowing nozzle through an air source so that the air blowing nozzle blows water onto the end cap of the four-way valve placed on the placement rack.

[0006] As an optional solution, the top of the air nozzle is provided with a support part for supporting the four-way valve end cover near the center position, and the top of the air nozzle is provided with an air hole near the edge position. The air hole corresponds to the position of the four-way valve end cover that needs to be blown with water. There are multiple air holes and they are evenly distributed around the support part.

[0007] As an optional solution, the number of air holes is 8 to 16.

[0008] As an optional solution, a first limiting groove adapted to the connecting pipe of the four-way valve is provided on the side of the top of the placement rack near the opening groove, and a second limiting groove adapted to the bracket of the four-way valve is provided on the other side of the top of the placement rack near the opening groove.

[0009] Alternatively, the air source may be an air pump.

[0010] As an optional solution, a workbench is also included. The frame is fixedly installed on the top of the workbench near the center. The top of the workbench is in the shape of a collection trough with baffles around it. A water outlet is provided on one side of the top of the workbench, and a water pipe is fixedly installed at the bottom of the water outlet.

[0011] The beneficial effects of this utility model are as follows: (1) This utility model has a water blowing function, which can remove the cooling water remaining in the end cap position after cooling, and avoid the welding material not flowing into the depth when the main valve and the end cap are welded, which will cause air holes between the main valve and the end cap, resulting in leakage quality problems in the four-way valve finished product, thus ensuring the quality of the four-way valve finished product; (2) The placement rack, the first limiting groove and the second limiting groove can cooperate to restrict the position of the four-way valve, ensuring that the water blowing process can be carried out stably; (3) The workbench is in the shape of a collection trough, which can recover the cooling water blown out in the water blowing process, saving water resources.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings:

[0023] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, this utility model provides a water blowing device for the production of four-way valves, including a frame 1. A through groove 12 is provided near the center of the frame 1, and an air nozzle 2 is placed within the through groove 12. The air nozzle 2 is fixedly mounted on the frame 1 with screws. A placement rack 11 for placing a four-way valve 3 is fixedly mounted on the top of the frame 1 by welding or screws. The placement rack 11 is a C-shaped cylinder with an open slot on one side. The placement rack 11 is placed vertically, and the main valve 31 of the four-way valve 3 is adapted to the placement rack 11. The placement rack 11 covers the air nozzle 2. Air is supplied to the air nozzle 2 through an air source 7, causing the air nozzle 2 to blow water onto the end cap of the four-way valve 3 placed on the placement rack 11. The air source 7 can be an air pump. This water blowing device has a water blowing function, which can remove the cooling water remaining at the end cover after cooling. This prevents the solder from flowing into the end cover incompletely during the welding of the main valve 31 and the end cover, which could cause air holes between the main valve 31 and the end cover and lead to leakage in the finished four-way valve 3, thus ensuring the quality of the finished four-way valve 3.

[0024] Based on the above embodiments, such as Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, a support portion 22 is provided near the center of the top of the air nozzle 2 to support the first end cap 32 or the second end cap 33 of the four-way valve 3. Specifically, the flat portion of the first end cap 32 or the second end cap 33 of the four-way valve 3 can fit against the support portion 22, providing support for the first end cap 32 or the second end cap 33. An air hole 21 is provided near the edge of the top of the air nozzle 2, corresponding to the position of the first end cap 32 or the second end cap 33 of the four-way valve 3 where water needs to be blown. There are multiple air holes 21, evenly distributed around the support portion 22; specifically, the number of air holes 21 is 8 to 16. In this embodiment, 14 air holes 21 are used.

[0025] Based on the above embodiments, such as Figure 2 and Figure 5 As shown, a first limiting groove 111, adapted to the connecting pipe 34 of the four-way valve 3, is provided on the top side of the placement rack 11 near the opening groove, and a second limiting groove 112, adapted to the bracket 36 of the four-way valve 3, is provided on the other side of the top of the placement rack 11 near the opening groove. The placement rack 11, the first limiting groove 111, and the second limiting groove 112 work together to restrict the position of the four-way valve 3 on the placement rack 11, ensuring the stable operation of the water blowing process.

[0026] Based on the above embodiments, such as Figure 1 As shown, it also includes a workbench 6. The frame 1 is fixedly installed on the top of the workbench 6 near the center. The top of the workbench 6 is shaped like a collection trough with baffles around its perimeter. A water outlet 61 is provided on one side of the top of the workbench 6, and a water outlet pipe 62 is fixedly installed at the bottom of the water outlet 61. The outlet of the water outlet pipe 62 can extend into the collection container. The workbench 6 is shaped like a collection trough, which allows for the recycling of cooling water blown out during the water blowing process, thus saving water resources.

[0027] During installation, this water blowing device should be installed at a separate workstation next to the welding station. For example... Figures 1 to 8 As shown, during operation, the worker takes the four-way valve 3, which has been welded to the first end cap 32 and cooled, from the welding station. Then, the worker places the main valve 31 on the placement rack 11 of the water blowing device, so that the connecting pipe 34 of the four-way valve 3 is located in the first limiting groove 111 and the bracket 36 of the four-way valve 3 is located in the second limiting groove 112. At this time, the second end cap 33 of the four-way valve 3 is in contact with the support part 22 of the air blowing nozzle 2. Then, the power supply of the air source 7 is turned on, and the air source 7 supplies air to the air blowing nozzle 2 through the air supply pipe 6. The gas in the air blowing nozzle 2 is sprayed out from the air blowing hole 21 to remove the cooling water remaining at the position of the second end cap 33. Multiple air blowing holes 21 can evenly blow away the cooling water remaining at the position of the second end cap 33, completing the water blowing process for the position of the second end cap 33 of the four-way valve 3. Finally, the staff put the four-way valve 3, which had been blown with water from the second end cap 33, back into the welding station. The welding station then welded the main valve 31 to the second end cap 33. Since there was no residual cooling water at the second end cap 33 during welding, the welding quality was high, ensuring the quality of the finished four-way valve 3.
