Description

Technical Field

[0001] The utility model mainly relates to the technical field of air-conditioning four-way valve processing, and specifically relates to a welding tooling for an air-conditioning four-way valve. Background Technique

[0002] The four-way valve is an indispensable component in refrigeration equipment and is a control valve with four oil ports. The working principle of the four-way valve is that when the solenoid valve coil is in the power-off state, the pilot slide valve moves left under the drive of the compression spring on the right side. The high-pressure gas enters the capillary tube and then enters the right-end piston cavity, and the gas in the left-end piston cavity is discharged. Due to the pressure difference between the two ends of the piston, the piston and the main slide valve move left, making the exhaust pipe communicate with the outdoor unit connection pipe, and the other two connection pipes communicate with each other, forming a refrigeration cycle. The common faults of the four-way valve include insufficient flow, poor commutation, etc.

[0003] During the processing of the four-way valve in an over-temperature environment, due to multiple plastic sliders inside it and the absence of a continuous and stable temperature control mechanism at present, the valve body is deformed or even melted due to high-temperature welding, resulting in the deformation of the plastic parts inside the four-way valve, and even melting, so that the entire air conditioner will lose its air-conditioning function, increasing the unqualified rate of the four-way valve. The repair will greatly increase, and the production cost will be increased, and the product quality will be reduced. Content of the Utility Model

[0004] The technical solution of the utility model aims at the technical problem that the existing technical solutions are too single, and provides a solution significantly different from the existing technology. Specifically, the utility model mainly provides a welding tooling for an air-conditioning four-way valve to solve the technical problem that during the processing of the four-way valve, sometimes the internal plastic slider is deformed and stuck due to high temperature and cannot move back and forth as mentioned in the above background technique.

[0005] The technical solution adopted by the utility model to solve the above technical problems is as follows:

[0006] A welding tooling for an air-conditioning four-way valve includes a valve body welding mechanism. The valve body welding mechanism includes a base. The base is provided with a first groove and a second groove, and the second groove is located above the first groove. The first groove is provided with a first through hole and a second through hole. The second groove is provided with a third through hole, and the third through hole and the second through hole are on the same central axis. A water outlet pipe is arranged in the first through hole, and a water inlet pipe is arranged in the second through hole, and the upper end of the water inlet pipe is butted against the lower edge of the third through hole.

[0007] Furthermore, baffles are arranged at the opening positions on both sides of the second groove, and the baffles are welded to the outer wall of the second groove.

[0008] Furthermore, a detachable bracket is arranged in the second groove.

[0009] Furthermore, a side frame is provided on one side of the outer wall of the first groove, and the side frame is welded to the outer wall of the first groove.

[0010] Furthermore, mounting holes are provided on the base, and the upper side of the base is welded to the outer wall of the first groove.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] By providing the base, the first groove, the second groove, the bracket, the baffle, the water inlet pipe and the water outlet pipe, the present utility model realizes that during the over-temperature welding of the four-way valve, circulating water cooling can be carried out, avoiding the valve body being in a high-temperature state, preventing the plastic slider in the four-way valve from deforming and jamming, and the problem of inability to move back and forth does not occur, reducing the unqualified rate and the return rate to the factory. Moreover, the second groove is located at the notch position of the first groove, which is conducive to the cold water in the water inlet pipe contacting the high-temperature valve body first, and at the same time enables the water that has been used and has a rising temperature to overflow from the notch position on the second groove and enter the first groove, reducing the mixing degree between the cold water and the water that has absorbed heat and increased in temperature, further improving the cooling effect, and facilitating the positioning of the four-way valve, meeting the automated processing mode in the factory, and having certain practical value.

[0021] Please refer specifically to the attached Figures 1-3 , an air-conditioning four-way valve welding tooling, including a valve body welding mechanism 1. The valve body welding mechanism 1 includes a base 11. A first groove 12 and a second groove 13 are provided on the base 11, and the second groove 13 is located above the first groove 12, which is beneficial for the cold water in the water inlet pipe 17 to contact the high-temperature valve body first. At the same time, the water that has been used and has a rising temperature overflows from the notch position on the second groove 13 and enters the first groove 12, reducing the mixing degree between the cold water and the water that has absorbed heat and increased in temperature, and improving the cooling effect. A first through hole 121 and a second through hole 122 are provided in the first groove 12. A third through hole 131 is provided on the second groove 13. The third through hole 131 and the second through hole 122 are on the same central axis. An outlet pipe 18 is provided in the first through hole 121. A water inlet pipe 17 is provided in the second through hole 122, and the upper end of the water inlet pipe 17 is butted against the lower edge of the third through hole 131.

[0022] Through the valve body welding mechanism 1, the above structure realizes that during the over-temperature welding of the four-way valve, circulating water cooling can be carried out, avoiding the valve body being in a high-temperature state, preventing the plastic slider in the four-way valve from deforming and jamming and being unable to move back and forth, reducing the unqualified rate and the return rate to the factory, and facilitating the positioning of the four-way valve, meeting the automated processing mode in the factory, and having certain practical value.

[0023] The specific operation is as follows. First, the base 11 is installed on the turntable (an existing device not shown in the figure) through bolts. Then, the valve body of the four-way valve is placed on the bracket 14 in the second groove 13. Subsequently, welding of the four-way valve is started. Meanwhile, cold water enters the second groove 13 from the water inlet pipe 17 to cool down the heated valve body. Then, the heated water overflows from the notch of the second groove 13, enters the first groove 12, and then is discharged from the water outlet pipe 18 to achieve water circulation cooling. After welding, the turntable performs station switching.

[0024] Please refer specifically to the attached Figure 2 and the attached Figure 3 On both sides of the opening of the second groove 13, baffles 15 are provided, and the baffles 15 are welded to the outer wall of the second groove 13. Through the baffles 15, the openings on both sides of the second groove 13 are sealed. A detachable bracket 14 is provided in the second groove 13. Through the bracket 14, the valve body placed in the second groove 13 is lifted to avoid the water inlet position being blocked. On one side of the outer wall of the first groove 12, a side frame 16 is provided, and the side frame 16 is welded to the outer wall of the first groove 12. Through the side frame 16, the pipes on the four-way valve are supported. The base 11 is provided with mounting holes 111, and the upper side of the base 11 is welded to the outer wall of the first groove 12. Through the mounting holes 111, it is convenient to install the base 11 on the turntable.
