Description

Technical Field

[0001] This utility model relates to the field of laser technology, and in particular to an automatic bypass adjustment switch for a water cooling system. Background Technology

[0002] Laser welding and cutting machines are widely used in various industries for welding and cutting metals and non-metals. Market demand is increasing. To meet the needs of high-power use and improve service life, water cooling is usually used for indirect cooling of lasers. Existing lasers do not have automatic cooling adjustment functions, which makes it impossible for the laser heat to be dissipated in time. Moreover, when the laser is not in use and water is flowing through it, condensation is likely to occur, resulting in poor stability of the laser body and hindering stable laser output. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a bypass automatic adjustment switch for a water-cooling system. This switch prevents condensation on the laser, allows for flexible switching between water-cooling modes for indirect cooling of the laser, reduces heat generation, improves the stability of the laser body, and facilitates stable laser output.

[0004] The embodiments of this utility model are achieved through the following technical solutions:

[0005] An automatic bypass regulating switch for a water-cooled system, comprising:

[0006] Laser unit;

[0007] A water chiller, wherein the water outlet of the water chiller is connected to the water inlet of the laser unit through a first conduit, and the water outlet of the laser unit is connected to the water inlet of the water chiller through a second conduit.

[0008] An automatic adjustment switch unit is provided between the laser unit and the water chiller. The water inlet of the automatic adjustment switch unit is connected to the first conduit, and the water outlet of the automatic adjustment switch unit is connected to the second conduit. When the water inlet of the automatic adjustment switch unit is subjected to pressure A, the automatic adjustment switch unit opens the valve to make the first conduit and the second conduit interconnected.

[0009] The laser unit is equipped with a control element at its outlet for controlling the output of cooling water.

[0010] According to a preferred embodiment, the automatic adjustment switch unit includes a flow channel body, a steel ball, a pressure spring, and a clamping block. The flow channel body has an internal cavity that extends vertically. The steel ball, the pressure spring, and the clamping block are arranged sequentially from top to bottom within the internal cavity. The steel ball fills the upper end of the internal cavity, and the upper port of the internal cavity is smaller than the diameter of the steel ball. The clamping block is located at the bottom of the internal cavity and does not block the communication between the internal cavity and the lower port of the flow channel body. When the steel ball is subjected to a downward force greater than the force of the pressure spring, the steel ball moves downward from the upper port of the internal cavity.

[0011] According to a preferred embodiment, the control element is a solenoid valve.

[0012] According to a preferred embodiment, the upper end of the inner cavity is narrower at the top and wider at the bottom.

[0013] According to a preferred embodiment, quick connectors are provided at both the upper and lower ends of the flow channel body.

[0014] The technical solution of this utility model embodiment has at least the following advantages and beneficial effects:

[0015] This utility model is equipped with an automatic adjustment switch unit. When the laser is turned off, the automatic adjustment switch unit can make the inner cavity of the flow channel body connected to the first conduit and the second conduit respectively, so that the cooling water can be directly returned to the water chiller. This avoids condensation on the laser and can flexibly switch the water cooling mode to indirectly cool the laser, thereby reducing the heat generation of the laser, improving the stability of the laser body, and facilitating the stable output of laser light.

[0024] Example

[0025] Please refer to Figures 1 to 3 An automatic regulating switch for bypassing a water-cooled system includes: a laser unit 1; a water chiller 2, the outlet of the water chiller 2 being connected to the inlet of the laser unit 1 via a first conduit 7, and the outlet of the laser unit 1 being connected to the inlet of the water chiller 2 via a second conduit 8; an automatic regulating switch unit is provided between the laser unit 1 and the water chiller 2, the inlet of the automatic regulating switch unit being connected to the first conduit 7, and the outlet of the automatic regulating switch unit being connected to the second conduit 8; when the inlet of the automatic regulating switch unit is subjected to a pressure of A, the automatic regulating switch unit opens a valve to make the first conduit 7 and the second conduit 8 interconnected; the outlet of the laser unit 1 is provided with a control element for controlling the cooling water output of the laser unit 1.

[0026] Optionally, the automatic adjustment switch unit includes a flow channel body 3, a steel ball 4, a pressure spring 5, and a clamping block 6. The flow channel body 3 has an inner cavity 9 that runs vertically through it. The steel ball 4, the pressure spring 5, and the clamping block 6 are arranged in the inner cavity 9 from top to bottom. The steel ball 4 fills the upper end of the inner cavity 9, and the upper port of the inner cavity 9 is smaller than the diameter of the steel ball 4. The clamping block 6 is located at the bottom of the inner cavity 9 and does not block the connection between the inner cavity 9 and the lower port of the flow channel body 3. When the steel ball 4 is subjected to a downward force greater than the force of the pressure spring 5, the steel ball 4 moves downward away from the upper port of the inner cavity 9.

[0027] Optionally, the control element is a solenoid valve 10.

[0028] Optionally, the upper end of the inner cavity 9 is narrower at the top and wider at the bottom.

[0029] Optionally, quick connectors 11 are provided at both the upper and lower ends of the flow channel body 3.

[0030] The working principle of this utility model:

[0031] In this embodiment, as shown in the appendix Figure 3 As shown, the arrow indicates the direction of coolant or cooling water flow. It first flows in from the upper port of the main body 3. Due to the pressure exerted by the coolant or cooling water on the steel ball 4 and the pressure spring 5, the pressure spring 5 is compressed, and the steel ball 4 is separated from the upper port of the inner cavity 9. The coolant or cooling water can flow into the inner cavity 9 through the gap between the upper port of the inner cavity 9 and the steel ball 4. The coolant or cooling water in the inner cavity 9 flows through the pressure spring 5 and the clamping block 6. The clamping block 6 has a vertically hollow channel D, which can lead the liquid in the inner cavity 9 to the lower port, and finally flow out of the quick connector 11 into the second pipe and flow back into the water chiller 2, completing the circulation of coolant or cooling water.

[0032] When the water pressure is greater than A, the water pressure overcomes the elastic force of the pressure spring 5. The coolant or cooling water compresses the pressure spring 5 downward through the steel ball 4. The pressure spring 5 can be a spring. The steel ball 4 disengages from the upper port of the inner cavity 9, forming a gap between them that allows coolant or cooling water to flow. That is, when the laser unit 1 is not working, the water outlet of the laser unit 1 can be stopped by controlling the solenoid valve 10. In other words, the first conduit 7 can no longer supply water to the inlet of the laser unit 1 (it cannot output through the output end of the laser unit 1 to form an output path). Therefore, the water pressure of the coolant or cooling water in the first conduit 7 increases, pushing the pressure spring 5 and flowing into the inner cavity 9 through the gap between the steel ball 4 and the upper port of the inner cavity 9. Finally, it flows into the second conduit 8, which flows to the water chiller 2, completing the return flow of coolant or cooling water. The pressure spring 5 can be set according to actual needs, and springs with different elastic forces can be selected. In addition, the water pressure A can be adjusted according to the external water pump or other equipment.

[0033] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
