Description

Technical Field

[0001] This application relates to the technical field of heating water valves, and in particular to a device for testing internal leakage of heating water valves. Background Technology

[0002] The heater core valve is an important component of a car's air conditioning system. It controls the flow of engine coolant to the heating system. When the driver turns on the heater, the valve opens, allowing heated coolant to flow into the heater heat exchanger, thus warming the air blowing through it and providing warmth to the car's interior. When heating is not needed, the valve closes, preventing coolant from flowing in, thereby saving energy and preventing the car interior from overheating.

[0003] A search revealed that Chinese Patent Publication No. CN212779774U discloses a test platform for internal leakage of a heating water valve. The platform includes a first flow control valve and a second flow control valve. By opening the first flow control valve and closing the second flow control valve, the water pressure flowing through the heating water valve can be increased, which can meet different test requirements. A pressure gauge can be used to detect the water pressure flowing through the heating water valve.

[0004] Regarding the aforementioned technologies, the inventors discovered the following drawbacks: it is difficult to dry the tested water valve. If the residual moisture cannot be removed, it may cause corrosion of the metal components inside the heating water valve. In particular, if the water contains electrolytes or contaminants, the risk of corrosion will be higher, thereby affecting its normal switching function and causing the heating system to malfunction.

[0021] The following is in conjunction with the appendix Figure 1 —4. This application will be described in further detail.

[0022] This application discloses a device for testing internal leakage of a heating water valve.

[0023] like Figure 1 As shown, a heating air valve internal leakage test device includes a housing 1, an air box 10 is provided on the rear side of the housing 1, a water valve 11 is provided on the top of the housing 1, an operation panel 12 is fixedly installed on the top of the housing 1, and a drying mechanism 2 is provided on the top of the operation panel 12 and inside the air box 10. The drying mechanism 2 includes a heating tube 20 for providing heat.

[0024] Please see Figure 2The drying mechanism 2 includes an air inlet slot 25 located on the rear side of the air box 10. A baffle net 26 is fixedly installed inside the air inlet slot 25. Multiple heating tubes 20 are fixedly installed on both sides of the inner wall of the air box 10. Fan frames 27 are also fixedly installed on both sides of the inner wall of the air box 10. Multiple fans 28 are fixedly installed at the bottom of the fan frames 27. The multiple fans 28 are located above the multiple heating tubes 20. An air duct 29 is fixedly connected to the top of the air box 10. The fan frames 27 are used to fix the multiple fans 28 and prevent the multiple fans 28 from vibrating and falling off during operation. The multiple heating tubes 20 are used to provide heat for the drying process. The baffle net 26 is used to block particulate dust carried in the air when the air is drawn in.

[0025] Please see Figure 2 The drying mechanism 2 also includes a drying box 21 fixedly installed on the top of the control panel 12. The other end of the air duct 29 is connected to the top of the drying box 21. A connecting pipe 22 is fixedly connected to the top of the drying box 21. An air box 23 is fixedly installed at the bottom of the connecting pipe 22. Multiple air nozzles 24 are fixedly installed at the bottom of the air box 23. By starting multiple fans 28, external air is drawn through the air inlet slot 25. At the same time as the air is drawn, the air is heated through multiple heating pipes 20. The heated air is then transported through the air duct 29 and enters the interior of the air box 23. The air is then sprayed out through the air nozzles 24 to dry the moisture on the surface and inside of the water valve 11, preventing the water valve 11 from being corroded by moisture and effectively protecting it.

[0026] The top of the control panel 12 is provided with an adjustment and fixing mechanism 3, which includes a meniscus 36 for clamping and fixing.

[0027] Please see Figure 4 The adjusting and fixing mechanism 3 includes a fixing block 31 fixedly installed on the top of the operating plate 12. A mounting block 32 is fixedly installed on the top of the fixing block 31. A threaded hole 33 is opened on the top of the mounting block 32. A threaded post 34 is threadedly connected inside the threaded hole 33. A handle 35 is fixedly installed on the top of the threaded post 34. A meniscus 36 is fixedly installed at the bottom of the threaded post 34. The hose 43 is in contact with the bottom of the meniscus 36. By manually turning the handle 35, the threaded post 34 rotates inside the threaded hole 33, so that the meniscus 36 contacts the hose 43, thereby clamping the hose 43 and preventing it from falling off during water testing, thus effectively improving stability.

[0028] The interior of the housing 1 is equipped with a testing mechanism 4, which includes a hose 43 for flushing.

[0029] Please see Figure 3The testing mechanism 4 includes a submersible pump 41 fixedly installed on the bottom wall of the housing 1. The output end of the submersible pump 41 is fixedly connected to a T-shaped pipe 42, and a hose 43 is fixedly connected to the left and right ends of the T-shaped pipe 42. The pumped water is diverted through the installed T-shaped pipe 42 for further testing.

[0030] Please see Figure 3 A mounting bracket 44 is fixedly installed on the top of the housing 1. The mounting bracket 44 is fixed to the bottom of the operating panel 12. Stabilizing blocks 45 are fixedly installed on the left and right sides of the mounting bracket 44. The hose 43 is located inside the stabilizing block 45 and is connected to the water valve 11. By starting the submersible pump 41, clean water inside the housing 1 is drawn and flows into the two hoses 43 through the T-shaped pipe 42. The hoses 43 are connected to the water valve 11 to test the leakage of the water valve 11.

[0031] Please see Figure 3 A water hopper 46 is fixedly installed at the bottom of the control panel 12, and a water box 47 is fixedly installed at the bottom of the water hopper 46. The water box 47 is connected to the housing 1. If the water valve 11 leaks, water will enter the interior of the water box 47 from the water hopper 46 and eventually return to the interior of the housing 1, realizing water recycling, effectively protecting water resources and avoiding water waste.

[0032] The installed drying mechanism 2 is used to dry the water valve 11, remove water stains from the surface of the water valve 11, prevent water stains from remaining, and prevent corrosion of the surface of the water valve 11. The installed adjustment and fixing mechanism 3 is used to fix it and keep it stable during retesting. The installed testing mechanism 4 is used for water testing, so that the water can be reused and water resources can be avoided.

[0033] The implementation principle of the heating water valve internal leakage testing device in this application embodiment is as follows: The installed drying mechanism 2 is used to dry the water valve 11, removing water stains from its surface to prevent corrosion. The installed adjusting and fixing mechanism 3 is used for fixation to ensure stability during testing. The installed testing mechanism 4 is used for water testing, allowing for water reuse and avoiding water waste. The installed fan frame 27 is used to fix multiple fans 28, preventing vibration and potential detachment during operation. Multiple installed heating tubes 20 provide heat for the drying process. The installed baffle 26 blocks airborne dust particles during air extraction. By activating multiple fans 28, external air is drawn through the air inlet slot 25. Simultaneously, air passes through multiple heating tubes. The air is heated by the duct 20 and then transported through the duct 29 into the air box 23. The air is then sprayed out through the nozzle 24 to dry the moisture on the surface and inside of the water valve 11. The handle 35 is manually turned so that the threaded post 34 rotates inside the threaded hole 33, causing the meniscus 36 to contact the hose 43 and clamp the hose 43. The water is then diverted through the installed T-tube 42 for further testing. The submersible pump 41 is started to draw clean water from inside the tank 1 and flows through the T-tube 42 into the two hoses 43. The hoses 43 are connected to the water valve 11 to test for leakage. If the water valve 11 leaks, the water will enter the leak box 47 from the leak hopper 46 and eventually return to the inside of the tank 1, realizing water recycling and effectively protecting water resources and avoiding water waste.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
